Method and device for the automatic formation of lines of predeterminable maximum length from a given text

In many offices, letters often have to be constant or at least similar texts are written using any of the known copying processes or copy processes therefore cannot use, because we wanted us for various reasons is, your recipient does not receive a letter recognizable as a duplicated letter, but to send an original letter. Letters must therefore be written in the original «although the texts are repetitive routine texts represent the same wording. This is the most common case in sales letters, in the case of reminder letters and also in the case of letters »which somehow involve obtaining one Related to the order.

The development of so-called typewriters, with which these are always repetitive original letters, it entailed, that finally a certain organizational technique arose to deal with letters as well to produce with the help of a typewriter that do not have the same text from beginning to end; because you can also get letters from constant Put together paragraphs, taking the individual TVile of a Letter can be found in a kind of card index.

Such machine units are generally aijs a hole. aggregat. for punching the control strip for the actual typewriter as well as that from a typewriter and a control unit composite typewriters.

All functions of the typewriter, such as carriage return, line feed etc., are entered in the control holes in the control strip. In the Manufacture, des> Tax strip is not to be dealt with differently than whom »one writes a letter on a normal typewriter.

Recording media are used, ζ. B. a magnetic tape, which has the advantage has that the coded recorded data and other characters can be deleted or corrected particularly easily at any time, in whole or in part.

The division of the lines of the text to be saved is in general by operating the typewriter when setting up the recording medium with simultaneous visual inspection of the sheet clamped in the printing unit. But Ks is also known, namely from the US patent 3 063 536, the line length of the text automatically combined from two different tracks of a recording medium to be determined by the machine. Often, however, the task is to arrange a text arrangement in relation to what is in the form of a letter, for example To change the text with regard to the line length depending on the sheet format; for this purpose the text had to be rewritten and the reduced or increased length of the lines can be determined by the operator in the known manner. This kind of text rearrangement is very much expensive.

The invention eliminates this disadvantage by means of a method for automatic Formation of lines of predeterminable maximum length from a given text in a certain line arrangement, in which the given text is divided into lines of a certain maximum length of the lines coded on a first recording medium scannable text with change of the maximum

* length of the cells rearranged on a second, similar recording medium

or to control a serial printing unit or both » at the same time, by scanning the data · and function characters from first recording medium intended for hyphenation, word hyphenation and end of line essential characters and character strings, such as space, Hyphen, carriage return and tabulation, possibly in conjunction with a data character, are evaluated differently, depending on whether the respective character or character sequence in the cell to be formed in accordance with the new row division within a a certain number of digits is located from the rightmost cell edge to the left extending edge area or outside this area.

Simply by setting the new desired maximum length on the printer it is thus possible according to the invention to determine the cell lengths of a text the lines of text without the intervention of the operator of the typewriter to shorten or lengthen. In the method according to the invention is for this purpose in the control circuit when recognizing or executing one of the essential characters according to the previously described method an advantageous measure according to the invention in each case one or a part represented by four rearrangement stages; these as well as the evaluation of the Individual read characters of the existing text are identified in the subclaims 2 to 17 in detail.

A particularly advantageous device for carrying out the method according to the invention is seen in the fact that this consists of an ale typewriter trained serial printer, two similar magnetic tape

Stations and a relay circuit that can be controlled via a switch and keypad exists, with one each as a switch and memory for the individual functions act ame s relay provided let. With the help of this execution can during the transmission of the text from one storage station to another the division of lines can be changed and at the same time the changed text can be printed out in the printer. This means that the original line layout of the text remains received, and d <-r the system operator can use the new line division during monitor the process. Changing the line length of a given text is referred to as "rearranging" in the following description.

When the rail 45 is pressed, an empty step takes place. When you press the Function key 46 the printer performs a carriage return operation * During certain correction processes, the 4? Key is used instead of the normal carriage return key 46. pressed. On the one shown in FIG There is also a margin lever 48 for the printer keyboard left edge and a margin setting lever 49 for the right edge.

The printer 3 is specially designed for use with the tape unit /. Its characteristics and the changes necessary for use with gang 1 are taken from Flg. 5 _S 6,? and 8 can be found. As mentioned, the writing head 50 of the printer is mounted on a carriage 51 which can be moved parallel to the platen 52 and is guided all the way to the left in accordance with the position of the edge setting lever 48. During pre-writing, the carriage 51 is shifted to the right in steps or for tabulation until it strikes the right margin setting lever 49. At the bottom of the slide 51 is a spur 53 _ä with a RandabfÜhlheb®! 54 interacts, which in turn is assigned to the edge setting lever 49 for the right edge "A part 53a of the shoe 53 is designed so that it moves the H®b" 54 a certain distance when it becomes effective "A second part 53b of the spur 53 also cooperates with the lever 54 and moves it over a longer distance®. When the Sehlitten "reached 51 sein® position at the right edge, the so-called Randbareich, in which the portion 53b d @ s shoe 53 is in contact with is d®m lever 54, a Stoppzuetanä is displayed. When the carriage 51 is between the margin setting lever for the left margin and the point where the part 53a first contacts the lever 54

809901/0176 *

if

cooperates, is located, the carriage 51 is considered to be outside the "tandbereich" located.

The term "edge area" defined by the margin setting levers determines this Behavior of the machine in response to various characters that are read from the tape in tape unit 1. According to the principles described here The machine reacts differently to the rearrangement process, depending on whether the slide is inside or outside the "edge area".

The edge sensing lever 54 has a lug 54 a, which is adjacent to a rotatably mounted bracket 55 is. If the lever 54 is moved to the right, the projection 54a acts on the bracket 55 and pivots it to the front the machine. According to FIGS. 6 and 8, the bracket 55 is mounted on a shaft which in turn is rotatably mounted in the typewriter frame. The rotary movement of the bracket 55 thus causes the shaft 56 to rotate the extreme left end of which a lever 57 is attached, which is on two shift levers 58 and 59 acts, namely by means of a respective approach 57a and 57b. When the edge sensing lever 54 (Fig. 6) has a first through the portion 53a of the " Shoe 53 is moved certain distance, the lever 57 is in turn moved to the left (Fig. 8), so that the projection 57a actuates the switching lever 58 and the associated switch 60 closes. If the carriage 51 is so far behind right has moved that the part 53b of the shoe 53 acts on the lever 54, the lever 57 is moved a further distance to the left (Fig. 8), so that

809901/0176

the projection 57b acts on the switching lever 59 and the switch 61 closes. Closing the switch 60 indicates that the carriage 51 has reached the "edge area ¹ ', closing the switch 61 indicates that the carriage 51 has reached the end of the" edge area "and that a stop condition is indicated.

When a character key is pressed on the keyboard 5, the assigned Intermediate lever 62 (Fig. 5) moved to the rear of the printer, whereby the Selector bracket 63 can be operated in different combinations and at the same time .A release bracket 64, via the linkage 65, the engagement of a single-turn clutch (not shown) and causes a pressure shaft 66 to rotate.

A movement of five selector bars 63, for example, has a corresponding one Actuation of the associated intermediate lever 67 to the front of the machine result in the rotating and tilting of the print head '50 for adjustment of a certain character. In addition, the actuated intermediate levers close various transmission contacts 68 and code checking contacts 69. The transmission contacts 68 lead to the tape unit 1 signals that the set Represent characters. The code checking contacts 69 are used to check the correct selection. .

Seven selector magnets 70 control the rotation and tilting of the write head 50. The seven magnets 70 with the designations TS ₈₁ Check Ti, R2a, Rl, R2 and

R-5 correspond to the various ones given in the code table above

Bit positions; two of the magnets, namely T1 and T2,> are assigned to the inclination movement of the writing head and four to the rotary movement Carriage return. The initiation of the function during input into the tape unit takes place under the control of intermediate levers which are assigned to the function keys on the keyboard 5. On the other hand, the initiation of the function necessary in m output operations when one of the magnetic tapes is scanned is performed under the control of the five operation selector magnets. A keyboard locking magnet 72 prevents the keys from being pressed during output and in certain other operating states,

The switching of the printer 3 is carried out under the control of an uppercase changeover solenoid 73 and a lowercase changeover solenoid 74 (Fig. 7). A toggle state contact 75 indicates whether the machine is i

is switched to uppercase or lowercase letters. There are also in the printer various other contacts provided. These include those shown in FIGS. 5, 8 and C2 pressure feedback contacts shown in Figs and the C3 uppercase and C4 lowercase contacts shown in Figures 27 and 29. The C5 contacts are closed by tabulating, stepping and switching back operations, while by a slide return or a revised carriage return, the C6 contacts are closed. the

8 09901/0176

C5 and C6 contacts are not shown in Fig. 5-8, but in Fig. 27 » indicated. In addition to the contacts listed above, there are also slide return blocking contacts 76 (Fig. 7 and 27) and tab »Locking contacts 77 (Fig. and 29).

The tape unit I will now be explained.

In the tape unit 1, two tape stations 6 and 7 are provided; this allows a shuffling of data as you type from the keyboard into the band of the Cassette 8 at the tape station 8 and from the tape of the cassette San of the station 7. In addition, individual blocks of information can be changed or searched for printing. Furthermore, both during printing from the tape of the cassette 8 or from the tape of the cassette 9 as a line rearrangement also during a transfer from tape 9 to baud 8 be made.-,

The mechanical parts of the Baadeinheil 1 are described with reference to FIGS. JB _8, 10, 11 and 12. In FIG. 9, the tape stations 6 and 7 and the associated tape cassettes 8 and 9 are shown on the right, corresponding to the front of the tape unit 1. The tape cassette 8 is also visible in FIG. The switches 78 and 79 shown in FIG. 9 indicate that the cassette 8 or for winding and unwinding the tape is in the correct position. According to FIGS. 9 and 10, a magnetic tape 80 is fed through the link © Baadstation of the tape '

For recording and reading characters on the tape 80 or 81, the magnetic heads 96 and 97 are moved back and forth with the magnetic head carriage 88 across the associated tape 80 and 81, respectively. As already mentioned in connection with FIG. 2, information bits are recorded at an angle of 45 to the direction of movement of the magnetic heads 9G and 97 note that the 45 bit positions can be read in both the transverse and the longitudinal direction of the tape. The search for a particular block of information on the tape 80 or 81 is effected in that the magnetic head slider 88 is adjusted with the heads 96 and 97 on the search-bit channel (Fig. 2). The search process can then be carried out on each tape in the longitudinal direction of the tape.

The carriage 88 has a projection 99 which slides past the armature 100 on the search magnet 98. If the magnet 98 is excited, the armature is pulled out of the path of the projection 99. If, on the other hand, a search operation is required, the magnet 98 is switched off, and as a result of the biasing action of a spring 101, the armature 100 protrudes into the path of the lug 99 during the return movement. The carriage 88 is held in the position in which the heads 96 and 97 read the search bit track. In order to return the slide 88 to its starting position, the magnet 98 is again A excited, pulls the armature 100 out of the way and enables the slide 88 to return to its starting position. The switch 102 (FIG. 9) is actuated when the carriage 88 is in the correct search position. The switches 103 are referred to as home position switches and are switched each time the carriage 88 makes a reciprocating movement.

such as B, when searching and winding quickly, it is desirable to use the pawl 118 to be released from the indexing wheel 104. That happens under the Control of a pawl magnet 113, the lever 112 against the Clockwise {Fig. 11) adjusted to remove the pawl 118 from the wheel to dig. Meanwhile, a shoe attached to a lever 115 becomes 114 brought to act on a clutch spring 116 changes the transmission ratios in the clutch and causes a fast forward of the tape. The switches 117 indicate that the pawl 118 is from Index wheel 104 has been disconnected.

According to FIG. 10, which shows the left station 7, but also complementary for the right station 7 applies, belt limit switches are provided to indicate the end of the belt. By means of a tensioning lever 121 with a spring 122, the band 80 held under a certain tension. A tape carrier magnet 123 actuated an angle lever 124 for lifting a pressure head 146, the causes the tape 80 to rest against the magnetic head 98. The switches 145 are closed when the pressure head 146 is raised to indicate that the tape has been properly placed against the magnetic head 96.

The indexing wheel 104 is located on a shaft 126, which in turn carries a sprocket 127, which is used to drive the belt 80 and for this purpose engages in its perforations 19 (FIG. 2). On its way through the assembly, the tape 80 runs through a tape guide 128 on a take-up

Before the detailed circuit description for the various operations First of all, the functioning of the whole system is shown using the block circuit diagram viewed from FIG. 49.

In Fig. 49, similar to Fig. 1, the tape unit 1, the printer 3, the '

Control panel and keypad 4 and the keyboard 5 are shown. Furthermore, the Schematic representation according to Fig. 49 several areas which are during recording and reading data. When recording data, they take the following route: Data and function characters are taken from the keypad or the keyboard 5 entered and via a cable harness 14 one OR circuit 15 is supplied. The output signals of this OR circuit get through the cable bundle 1? to thyratrons 150 to 157 for the purpose the excitation of the relays R59 to R37 in the relay bit register 16, their respective f

Combination represent the relevant character. Certain contacts of the Relays R59 to R37 are contained in a coding block 210 which enables the selection of the bits to be recorded are determined under the control of a selection block 211 for the magnetic pulse generator.

the pulse generator emits a sequence of clock pulses MFl to MPIl optionally via a common magnetic excitation line MPC. The pulser 90 operates in synchronism with the movement of the magnetic heads across the magnetic tapes. The selection block 211 for the pulse generator 90 controls this in such a way that a series of bits representing the character to be recorded is fed to a pulse shaper 220 one after the other via the MPC line. From there, the pulses are transmitted over lines 22Ϊ and 222 to either the write / erase driver 182 or to the write / erase driver 183. The drivers 182 and 183 are write / release coils 188bjsw. 189 assigned. The selection of the combination of driver and head is determined under the control of station address circuits 223. ί _if:

To read data previously recorded on one of the magnetic tapes at station 6 or 7, the mode selection button 20 is turned to the corresponding position rotated. Then either the left reading coil 190 and the associated amplifier 224 or the right reading coil and the associated amplifier 225 is turned on. The output signals of the Amplifiers 224 and 225, respectively, are sent through the OR block 196 to to set a bistable read flip-flop 226. The respectively read through The on or off state of the Lteekippstufe is caused by the bits Line 227 is passed on to an and circuit 228. During the read operation clock pulses are supplied by the magnetic pulse generator 90

and via selection block 211 and bus 229 of the AND circuit 228 supplied. Its output signals are fed to the OR circuit 15 and ignite the thyratrons 150 to 157 via the cable 17, whereby the Associated relays R59 to R37 in bit register 16 are excited. the Setting of relays R59 to R37 is passed on through cable 215 to control print selections or functions of printer 3.

During the return of the ^ head, a check is carried out to ensure that- ^

provide that for each character recorded on the tape an odd Bit number is available. For testing, the tape unit 1 is automatically switched to reading, and pulses that are previously recorded by the magnetic head Bits represent are provided by amplifier 224 or 225 and by the line the error flip-flop 184 and bring them in the course of the read operation in the on or off state. That is the state of the fault flip-flop 184 signal is fed to the pulse shaper 220 and checked at a certain point in time towards the end of the reading cycle. In the case of |

of an error, the output of the pulse shaper 220 is determined by the Line 217 is fed to the thyratron 186 and ignites it; thereby becomes the relay Rill energizes and indicates the error. In this way the Error toggle 184 only used during a record operation. When reading, as each character is entered into the relay bit register, the state of the register is set to the correct parity by a circuit 218 checked out.

A seek operation is under the control of a relay counter 207 and search switch 208 is executed. The latter are preset to a count that is required by the reference number selection button 27 Represents information block. The search is carried out over the length of the tape with a high Speed. When identifying reference codes, these each recognized by the search string identifying block 198. That output signal of block 198 is fed to counter 207 through line 209 and switches him on. When the count of the counter is 20? with the one position of switch 208 matches, a "block found" signal is generated delivered on line 213. Also in Fig. 49 is a line shuffling area 205 and a line revision block 206 are shown.

As mentioned, the magnetic head slide (Fig. 9 and 12) is moved back and forth during an Arbeltstaktes so that the magnetic heads 96 and 97 are moved across the magnetic tapes assigned to them. During the back and forth movement of the carriage 88, the pulse generator 90 is rotated and thus supplies clock pulses in synchronism with the movement of the carriage 88 i

and the magnetic heads 96 and 97. The circuitry for the magnetic pulser and its pickup is shown in FIG. Its output signals are fed to the pulse shaper 220 and optionally transmitted via the line 19.11 according to FIG. 21, depending on whether the respective bit position represented by the magnetic pickups 1-11 has been selected by the relay coding lines 17.02 to 17.10 which are supplied by the CB-8 in FIG. 17 lead from FIG. 19.

The output pulses of the pulse generator 90 on line 19.11 are fed to the recording of the AND blocks 180 and 181 in FIG. 21; These control the magnetic head drivers 182 and 183 assigned to them, which in turn control the write / erase coils 188 and 189, in accordance with the gate control effected by the lines 17.12 and 17.13. Depending on which of the control relays R211 and R214 has been selected by the operating mode selector button 2Q , one of the two tape stations is controlled by the lines 17.12 and 17.13. The drive relay contacts for selecting the magnetic heads are shown in FIG.

According to FIG. 13, after the bits have been stored in the bit register, the pulse generator arm begins to deliver pulses in order to effect the selection of pulse generators. The pulses are transmitted via the common pickup line to the write / erase driver for the tape station in question, and finally to the magnetic head of this station.

Meanwhile, relay R77 talks over at 130 CB-I (Fig. 29), the contact 77-5 (Fig. 25) is switched and the +48 volt voltage for the clutch energizes the on-cycle relay R66, which is held by its contact 66-3 (Fig. 25).

As before, when the belt unit is switched on, relay R34 is energized, and the +48 volt voltage reaches Flg via line 25.02. 37 and the now toggled contact 34-4 to the upper portion of the Codler switch that has been pressed. The one placed on the top of the switch + 48-volt voltage then finds its way via certain 1-BiV 3-bit, 5-bit etc. designated paths and from there via lines 37.01 to 37. 20 to prepare the thyratrons and to enter the bit representation of the character to be encoded in the relay bit register. . *

The recording of the carriage return code and the associated transport code for a subsequent line change of the printed text is carried out ta explained in more detail below.

By pressing the carriage return key 46 on the keyboard 5 of the Printer 3, a cycle is initiated in the printer, so that the contacts CS to Fig. 27 are switched. The +48 volt voltage is then available Disposal of the C2 contacts, the C5 cortacts and the C6 cortacts, the Contact 77-4, contact 90-9, contact 34-7 and the carriage return transfer contacts in Figure 27, thereby energizing the carriage return transport relay R71 and through its own contact 71-1 and a contact 8S-2 to the +48 volt line 130 (Fig. 27). As a result of addressing of relay R71, relay contact 71-4 is switched and then the Side carriage return blocking relay R69 energized. The relay R69 is held over its own contact 89-4, playback contact 90-4 and contact 71-2 through contact 85-2 to the +48 volt power line 130.

After relays R69 and R71 respond, contact C6 returns to its Rest position back. When that happens, there is a voltage of +48 VoIt in Fig. 27 available via contact 90-3 and via line 27. 03 according to Fig. 29. From there the current path runs through a contact 77-2, a Diode and the now switched carriage return blocking contact 69-1 to Management 04/29 The line 29.04 leads to Fig. 26 and via line 26.05 See also Fig. 36. In Fig. 36 it can be seen that the line 26.05 connects directly to the

80 9 901/0 176

Line 36.03 is connected, which in Fig. 26 by the stop contact 80-8 and CB-5 runs to energize the clutch.

In Fig. 36, the transport contacts 85-1 are used to create a second Cycle to generate a transport code after the carriage return code which occurs during the first cycle, hereinafter referred to as circulation. Record the carriage return code the tape is similar to that for recording a character.

The response of the relay R77 has the excitation of the in-flow relay R66 result. The one-circulation relay is always energized when the Slide return key is pressed or if the "Revised slide return" key is pressed. The in-circulation relay is not made to respond by pressing any other buttons on the printer 3. That One-cycle relay R66 switches contacts 66-12 in Fig. 27 and together with contacts 71-3 causes the transport relay to respond R85. The R85 transport relay is held on its own Contact 85-4 (Fig. 26) and via CB-2 to 48 volts on line 130. As before mentioned, the contact leads 85-1 in Flg. 36 the +48 volt voltage again via line 36-03 to energize the rotary clutch in FIG.

As can be seen from Fig. 37, contact 85-3 conducts in conjunction with a contact 34-4 the 448 volt voltage across three diodes labeled "Transport" in the upper left corner of Fig. 37 for the encryption of the transport code. This leads to the creation of

80 990 t / 0 176

Bit signals on lines 37.01, 37.02 and 37.03 of FIG energize the thyratrons to store the bits representing a transport code.

To record the '* Flsvidierter carriage return "code according to 27 shows a signal path which is comparable to the normal carriage return path is for the Revised Carriage Return transfer contacts. When switching A voltage of +48 volts is available from C6 in the printer via 77-4, 90-9, 34-7 and the "Revised carriage return" transfer contacts, to energize relay R69 directly. In this case it is Slide return transport relay R71 is not involved, and as a result no transport cycle initiated under the control of the transport relay R85, as was the case during the normal carriage return cycle.

The encryption of the reset code on a tape in the tape unit is done by pressing the backshift key 37 on keypad 4. The back « Toggle encryption switch is shown as switch 6-1 in FIG. A voltage of +48 volts is applied to line 31.02 via contact 111-1, contact 90-1 and a switch to terminal 1 of the rucksack leading circuit loop supplied. The application of this +48 volt voltage takes place in a similar way to the other encryption switches 6-2, 6-3 and so on in Fig. 37. When you press the reverse key switch 6-1 a + 48-volt voltage through the line 37.06 according to Flg. 32 headed, to Fig. 32 is the 448 volt voltage on line 37.06 via a contact 66-?

to the Itrückschaltverschschlussa-Relais Π73 and energizes it. Relay R73 is held through its own contact 73-3 and one Contact 66-1 in Fig. 32.

In addition, in FIG. 32, the. Contact 73-1 um, and the +48 volt voltage then reaches the contact 75-3 and the now closed contact 73-2 to the return magnet of the printer 3. This creates a working cycle of the printer and the ribbon unit. As a result, the collector control relay R34 is energized and its relay contacts switch. In FIG. 32, the 448 volt voltage is then available via the contact 73-1 and the contact 34-5 and on the line 32.01 leading to Fig. 37. In Fig. 37, line 32.01 leads into a set of three diodes and causes the generation of the pulses to store the switchback character on the tape. The cycle continues, and the recording of the switchback sign takes place like the recording of any other encrypted character via the three "switching back" diodes in Flg. 37 and over lines 37.03, 37.04 and 37.05 according to Fig. 20, whereby the thyratron to get prepared.

When downshifting, it is advisable under certain circumstances that the so-called error correction downshift while it is in the in other cases it may be appropriate, according to the procedure just explained proceed with encryption for switching back.

As can be seen from FIG. 17, the gate circuits run on line 17.12 and 17.13 through a break contact 75 «4 of the jerk hold relay and one Normally open contact 73-4 of the reset encryption relay. Hence finds a jerk stop code is only recorded on the tape if the downshift button 37 on the control panel in FIG. 3 is pressed. A switch back operation in printer 3 which is the result of pressing the back switch key 149 in Fig. 4 does not result in an encryption operation. Instead of recording a downshift code, pressing the The reset button on printer 3 activates the reset relay R75 (Fig. 32> and a subsequent revolution, during which the tape in the holding unit 1 is switched back step by step under the control of the devices of FIG. According to Fig. 18, a contact 75-5 opens the circuit to Rill recording error relay to provide an error indication during the rack to prevent switching circulation. The switch-back magnet for each station will excited via a conact 75-2 when this is switched (Fig. 26).

In order to recognize van foformatlonsblöcken to enable on one of the magnetic tape, each information block is a group of 51 codes expected to be recorded when the reference code key 40 is pressed on the keypad (Fig. 3). As mentioned, these 51 codes are:

Fifteen ^ Autotnaöeches search codes, fifteen "Search" codes *, twenty check or "7" -Btt codes (mine z) and a slide back «

so

The already mentioned counter controls the recording of the codes in the order mentioned. The counter was initially set to 01 and is incremented in each cycle when codes are recorded. The counter circuit is under the control of a thyratron 192 in FIG. 22, but which is controlled by a + OR block 193 and a pulse on line 19.10 which occurs in each cycle during the recording of the reference code. By pressing button 40, switch 6-5 in F.ig. 39 closed. This switch is normally fed at +48 volts through contact 111-1, contact 90-1 and line 37.19 in FIG. 37 as for each of the encryption switches shown in FIG. When switch 6-5 is closed, the +48 volt voltage is passed through contact 66-5 and energizes reset relay R148 in Flg. 39. The purpose of relay R148 is to reset certain counting units shown in FIGS. 39, 40, 43 and 44. When the relay R148 is energized, the contact 148-5 (Fig. 39) switches over, and therefore the search relay RlSl responds. The various counters are fed with a +48 volt voltage from line 130 in FIG. 43, to be precise via contact 170-2 and a line 43.03 according to FIG. 9. The switching path then runs via a break contact 148-4 and via line 30.02 according to FIG. 40 and further via line 40.01 according to FIG. 44. If any of the counter relays R18Ö, R176, Ri73 in FIGS. 39 and 40 as well as R164, R16I and RISS in Fig. 44 were / are normally held by contact 148-4 in Fig. 39 via the path just described. However, as soon as the reset relay R148 is energized, contact 148 * 4 {Fig. 39) around and MSt all previously held counter relaia fall. In addition, switching over the contacts 140-4 causes the input to respond to the relay R133 in FIG. 39, so that the initial

# 03901/0170

Position of the counter is "01".

Next, the rotation of the belt unit 1 must be initiated in order to record the sequence of 51 predetermined codes on the tape. A +48 volt voltage from line 35.05 in Figure 35 to Figure 33 and above the line 33.02 according to FIG. 41 holds the relay R148 via various contacts labeled four-tens on the earth side in Fig. 41. As soon as the various counter relays have been reset, all relay contacts from 158-8 to 158-9 in Fig. 41 have opened, and Furthermore, relay contact 183-9 has switched so that relay R148 can no longer be held. When this happens, the 448 volt voltage runs off on line 33.02 via the now closed contact 148-1, via the now switched contact 151-5, the contact 145-1, the contact 141-11 and the line 41.04 according to FIG. 26. In FIG. 26, the +48 volt voltage causes on line 41.04 the response of the circulation clutch. As long as the search stop contact 145-1 in FIG. 41 remains closed, the clutch in the belt unit 1 is freewheeling.

The first code recorded during counting intervals 1 to 14 is the "automatic search" code, which is made up of bits 1 (Rl), 3 (H2a) and 6 (T.8.) Exists.

The division of the relay register takes place under the control of the Collector control contact 34-1 in Fig. 18. As is well known, as soon as the reset relay R148 drops out, a +48 volt voltage is applied to line 33.02

80990 1/0176

in Fig. 41 via the normally closed contact 148-1; Via the switched contact 151 -5 und'via a current path and line 41.04 described above Flg. 26 and energizes the rotary clutch. At the same time as the circulating clutch responds, there is a +48 volt path via lines 26.01 and Line 32.03 to energize the collector control relay R34. The be « indicates that as soon as the circulation clutch responds, a first 'automatic search' code is stored in the relay register when the Contact 34.01 switches over in Fig. 18. The sampling pulse for advancing the counter is very late in each cycle, and before the first occurrence of the sampling pulse on line 19.10 (FIG. 22) the circulating clutch is activated addressed at 235 of the cycle as well as relay R34. This means that before the counter is advanced from position 01 a second "automatic search" character has been stored in the relay register, where it is used for recording the character in the next cycle is ready. This situation remains, so that when the counter reaches level 14 and before it is switched to level 15, the Fifteenth "automatic search" character stored in the relay register has been. This way you will find fifteen "Automatic Search" codes recorded during this interval instead of the normally expected fourteen. The thyratrons 150 to 157 in Fig. 20 are via the Lines 41.05, 41.06, 41.07 and 51.09 in Fig. 41 are controlled.

The circuit for switching the thyratrons to record the "Automatic search" codes during the reference code sequence are as follows:

According to Fig. 41, a 448 volt voltage is always available at 164-5 when the search contact 151-5 has been switched, as in the present case. During the time intervals 01 to 10, the +4 becomes 8 volt via the normally closed contact 164-5, the normally closed contact 161-4, the normally closed contact 158-3 ,, and via line 41-06 to Fig. 37 and there the three diodes with it given the name "Automatic Search". This leads to ignition the Thyratrons füi * jcia%, eü ^ glige recording of the three the "automatic SucbenV> € or representing bits, as explained above. For the purpose of recording of the twelfth, thirteenth and fourteenth "Automatic.

The fifteenth Character, also called "automatic search", is recorded via a +48 VoIt voltage across the same circuit as for the twelfth, the -thirteenth and the fourteenth characters are fed, but with. the exception that when the count reaches fourteen, the contact 176-10 switches over and the circuit then through the relay contacts 180-11 and 183-10 according to management. 41.06 and from there to FIG. 37.

If; the relay counters have reached 15, the 448 volt voltage passes through the switched contact 176-10, the normally closed contact 180-11, the switched contact 183-10 and via line 41.05 directly to FIG. 20 and ignites the thyratron there 151 for recording a bit in the 3 search track.

Now the conditions when trying to get into the void area of the tape record, explained.

On each magnetic tape in the tape unit 1 there is a section of from which the oxide is removed. This section is used to display the circumference of the band evaluated. With each tape is after it is completely in its Cassette has been wound up, the associated magnetic head first hit this empty section. When trying to make a record in the section normally an error would result. So when the arrangement determines that the tape you are driving is completely wound up is, it inevitably brings the machine into the "recording" position, to come out of the blank portion on the tape in preparation for recording on a coated portion of the tape. This is true also when the machine is switched to "playback". I.e., if the Mode selection button 29 in the playback position and the tape in the winding state is, the machine is automatically and automatically to "record" switched and the tape switched gradually out of the empty area, until it is in the correct position under the magnetic head for playing the Data has been brought.

Every time the assembly is in the wind-up position, the wind-up relay 11121 (Fig. 34) excited by a + 48- ^ olt voltage on line 41i 02 from Pig. 41, originally from iieitung "S3VÖ2'al3

Then the +4 8 volt voltage is passed through the Rel & is 211-9 or the relay 214-8, depending on which device is used, it goes through the assigned winding sensing contacts * to the winding relay Rl 21 * irritate. As can be seen from FIG. 41, the same 448 Völt voltage is applied to line 33.02 via contacts 148-1 and 151-5, the now switched contacts 121-9 and 111-2, contact 14i-11 and via line 4i.Ö4 directed according to Fig. 26 in order to excite the circulation clutch, so that the 'step-by-step indexing of the tape is continued up to the beginning of the actual information and the tape is in the correct position for Aufaufzeiefinen or

Playback is.

During this time the machine tries to record transport codes. Their encryption takes place under the control of certain Helais points, which are indicated in FIG. 34; this includes contact 151-2, contact 121-12, which is now closed because the arrangement is in the wound-up state, the collector control contact 34-6 which is now closed and line 34.04 according to FIG. 37. This leads to three diodes with the designation "Transport", and from there the +48 volt voltage arrives via lines 37.01, 37.02 and 37.03 according to FIG. 20 and prepares the thyratrons for recording the transport codes. The +48 full voltage reaching the clutch on line 41.05 in FIG. 20 causes repeated excitation of the clutch as long as an attempt is made to record transport codes in the empty area. This is based on the fact that an error is displayed with every attempt to record and that the LR-lais IJlI (■ rregi. '_ ^: 8 0 9 9 0 f / 0 1 7 6

To find a specific information block, letter or a message such as B. the previously mentioned sample text, the search operation is used, which is described in more detail below. This is an arrangement is provided which is based on reference code identification elements responds to determine the situation of a particular message. Then the principles of row rearrangement described here apply to the selected Message applied.

The search relay R151 (Fig. 39) is energized when a search code is recognized on the tape or by pressing the search switch 5-5 (Fig. 39). For a search operation, the first thing to do is to reset those discussed above Counter circuits required. The reset relay R148 will, however energized after a winding relay 87 (Fig. 24) has responded for a winding operation. In Fig. 42 are the Kiner switch and the tens switch to specify a desired information block on which the search process is directed, shown in connection with various counter relay contacts. The ten switch has a first segment 260, a single contact 261 and a second blessing nt 262. The one-switch weeps a first Segment 263, a single contact 264 and a second segment 265. When one of the switches is turned, each of the segments retains its segments, as does the individual contact the same relative position to each other, but are rotated clockwise or counterclockwise, around a different one Establish counter reading for the search operation. If the switch position and the counter position match, an output signal is sent on line 42.03 43 generated. When the relay counter reading is lower than the switch reading 43, an indication is given on line 42.04 of FIG

80 9 90 1/0 17B-

search the arrangement in the forward direction. If, on the other hand, the relay count is higher than the information defined by the switch position, block, an output signal is passed on from line 42.02 according to FIG. 33, to initiate a winding operation.

After dividing the counter, a +48 volt voltage is available via contact 148-1 in FIG. 41. This is passed on via the now switched contact 151-5, the now switched contact 141-9 and line 41.01 according to FIG. 42, from where it passes through the relay contacts assigned to the ten switch. In accordance with the circuit shown in FIG. 42, an output signal is generated either on line 42.02 to initiate a winding operation, on line 42.03 to indicate alignment, or on line 42.04 to indicate that searching can continue in the forward direction. The very first time the +48 volt voltage comes across the circuit of FIG. 42, in the event that it finds its way through leads 42.03 or 42.04, the voltage across contact 150-2 is turned into passed Fig. 43 and through the line 43.01 in FIG. 33, to excite the A ufwickelrelais 87th The state of the "First Search" relay R150 therefore determines which functions the tape unit performs. The relay decode pyramid circuits in FIG. 42 and the switches may have been set to a counting state, represented by a voltage on line 42.02, to give the winding indication immediately to FIG. The response of the winding relay R87 results in the closing of the contact 87-5 in FIG. 41 and the discussion of the "first search" relay R150. After winding up and after

809901/0176 .. «, ... *. *

when the "first search" relay Rl 50 responds, the following impulses arrive via lines 42.03 and 42.04 in FIG. 43 through the now switched Contact 150-2 'and via line "43.02 according to Fig." 25. ' In Fig. 25 comes the Voltage through contact 147-1, contact 6G-3 and through conduction 25.07 according to FIG. 26 and energizes the rotating clutch 92.

At the beginning of the search operation, the magnetic head slider is moved œi3 über'das magnetic tape out, and the search-position solenoid 98 in Fig. 9 is held in the non-energized state, so that the armature of the magnet M

Kopfsoniitten Sß takes with him on the way back and holds the magnetic head over the search track (Fig. 36). The contact 151-1 is open because the simmering magnet 151 is energized, and therefore the contact 141-1 is switched and prevents a pulse from reaching the search position magnet 90 and energizing. In order to initiate the search operation, the pawl magnet 113 (FIG. 11) must be excited in order to lift the pawl 118 off the ratchet wheel 104 and thus bring the shoe 114 to interact with the clutch spring 116. The circuits for exciting the two pawl magnets are shown in Fig. 33 Λ

shown. During the seek operation, the tape unit reads do bits on the center track previously recorded during any recording operation. The circuits are switched in such a way that only six of the search bits or ten search bits are recognized, which generates an output signal for incremental advancement of the counters. 22, the bits that are read either by the left reading coil 190 or by the right reading coil Ii) I are read by the sensor block 194 or 11) 5 or by the "OR" block 19C donrSiichverbindc-Ittenti-15) 0 7.ιι ₍ "Λ'ίϋ1ΐΓΐ, the outside of the cathedral via an UborKotzerblock of

the line 10.02 in FIG. 22 is controlled. Whenever sufficient Bit number is recognized, the thyratron 192 is ignited via line 43.04, to energize ring 1 relay 170 in FIG.

As mentioned, the reference code consists of fifteen "automatic search" codes, fifteen search codes, twenty check codes and a carriage return code. The "Automatic Search" codes are used during the search sequence are not recognized, but are used to prevent further movement from the end of a block of information during normal read operations. In addition, this area serves as an acceleration area on the belt. The twenty check codes following the "automatic search" bits in the reference code arrangement are used for braking if the required Information block has been found. The ring 1 and ring 2 relay R170 and R1G7 control the step circuit of the counter relays Rl73 and Rl76 in Fig. 40, R180 and R183 in Fig. 39 and R158, Π161 and R164 in Fig. 44. The counter can count to 79. The excitation of the ring 1 relay Rl70 causes the switchover of contact 170-2 in Fig. 43 and the subsequent response of relay R167. When relay R167 responds, relay contact 167-1 opens and that Relay 170 in Fig. 43 drops out. This in turn causes relay R167 to drop out, and ring relays R167 and Rl70 are in their previous ones reset in the unactuated state.

This is done in such a way that the relay counter incrementally advances to the state have been searched for by one counting level above the Zühlstufe.des Blocks of information. Therefore, the relay counters are based on the count of the next information block, if this is the one after the one just found Block next is needed.

When the IU45 responds, the contact 145-2 in FIG. 30, M opens

and thereby the search magnet 151 is turned off. In Fig. 36, as soon as the search magnet drops out, the contact 151-1 closed, and the search position magnet 9Ä is excited and pulls its armature out of the path of the magnetic head carriage 88 so that it can return to the starting position. In Fig. 36 the initial position contact is closed as soon as the magnetic head is issued in the search position. This contact forms part of the switch arrangement 103 in FIG. 9.

In order to gradually move out of the area of the winding codes in the reference code area on the tape, the jump relay R114 has to be energized and the tape stepping mechanism has to be switched in the forward direction in order to get to the first character position of the information block. This function is brought about by the jumping relay in conjunction with the Zefien return relay.

The pulses from the pulse generators are different in the playback operation can be used than in a recording operation. The latter is used the pulse from the pulse generator 3 (the pulse generators are in the following for themselves numbered consecutively) to record the Hit-I location on the tape containing the Pulse from the pulse generator 4 to record the 2-IUt-S ^ eIIe, the pulse from the pulse generator 5 for the 3-bit digit, the one from the pulse generator ß for the 4-bit position that comes from the pulse generator 7 for recording the search bit position, the one from the pulse generator 8 for recording the Γ> «bit position, the one from the pulse generator 0 to record the 6-bit part that comes from the pulse generator 10 for recording the 7-bit digit and that from the pulser 11 for recording the 8-bit position of the tape.

According to Ι; 'ig. 18, CB-4 supplies a voltage of + 48-VoIt from 25 to 245 of the reading cycle. The +48 volt voltage is determined by a search contact 151-11 and a recording contact 3-6 is routed to the energization of the relays in the relay register according to the bits read from the tape. The relays are held in the bit register via line 29.06 from CB-I, the at 130 ° of the rotation closes and opens at 350 °. Also excites CB-I (Fig. 29) the relay 11.77, which responds in each cycle to start the time in the cycle show for which a character has been stored in the relay register. The information in the relay register are still through the line 29. 05 in Fig. 18 applied +48 volt voltage maintained. This line is the Holding coil of relay 1177 (Fig. 29) assigned, and a +48 volt voltage must have reached this relay in order for the information to continue in the Relay register can be held.

From Fig. 14 it can be seen that in order to keep the bits in the bit register certain printer folders normally have to remain closed until the printer accepts the character stored in the register Print aiB selected or the function defined by the character carried out has, e.g. tabulating, space, etc. A line called "Print ^ '" Line is used to indicate whether the printer has used the character stored in the relay register or not. According to FIG. 27, this begins

fitang with the +48 volt voltage on line 130 and runs through the contacts C2, C5 and CG and the now closed contact 90-3 and line 27 ^ 03 according to Fig. 29, where these to a now switched contact '77- 3

and from there the current path goes through contacts 116-8 and 119-1, various relay contacts with the designation Rl-Bit, R2-Bit etc. and via lines 250 and 251 to contact 114-2, then further through the collector control contact 33-11, the transport contact 85-5 to the holding coil of relay 1177, which holds it until the printer receives the Evaluates characters, d. H. brings to print. So that this current path just described is maintained, the relays in the relay register must also be the correct number of bits have been energized, d. i.e., with straight, i.e. wrong Bitzalü, leave the various relay contacts Rl-BiI, R2-Bit etc. in Fig. 29 the +40 volt voltage does not reach the holding coil of relay R77. If the number is even, the 448 volt voltage will be across the line instead '252 sent to energize the playback error relay Rl 12, which acts as a locking relay.

According to Fig. "29, a current path goes through the contact 65-9, the capital letter contact C3, the lower case letter C4, the tabulator contact and the type of changeover no. 1 contact to the up-shift and down-shift solenoids in the printer. When the printer is in the one switching position and the character just read from the bundle unit is in a different switching position must either the up-shift solenoid or the down-shift solenoid in Fig. 29 can be energized so that the switching position of the printer is matched to that of the character to be printed. Then a circuit runs through contact 37-5 or 37-6 depending on the condition of the. Printer and via line -2WÖ6 ria "ch Fig. 30. This reaches a contact

56-5 in Fig. 30. From the code table given earlier it can be seen that

80 990 1/0 176 ^; ■ '" ^:

they always contain an R2a bit and no H2 bit. Therefore, when a function sign is encountered, the circuit goes through the closed one

Contact 56-5 and the switched contact 53-5 and via line 30. 04 to the function magnet in Fig. 31. If an information sign is encountered 30, the path continues through the various contacts R2-bit, R2a-bit. Hl -bit and associated relay contacts to optionally to the rotation and tilt magnets contained in box 255 in FIG to be guided. The excitation 'either of the functional magnets in Fig. 31 or the character selection rotation and inclination magnet in Fig. causes the printer to circulate and the relevant function to be carried out or the printing of the relevant character. While running this During the process in the printer, the various printer contacts C 2, C5 switch and C6 in Fig. 27 and break the conduction through the test circuit in Fig. 29 and to the hold coil of relay R77. Via various feedback contacts the printer also initiates one more revolution of the belt unit. One of the last operations in the belt unit during each revolution is the step-by-step advancement of the tape to the next to be read Sign. However, if an error is detected, the tape will not advance but will stop so that the same character can be read again. This is different from the recording operation in which the stepping takes place before the detection of a recording error, after which the tape must then be switched back to the previous position.

The step control for the tape unit is shown in FIG. Of the Playback error contact 112-2 prevents the tape unit from advancing. If an error is detected during the recording operation.

the step has already taken place, and the error correction backspace key 14 on the keyboard 5 in FIG. 4 is to be operated to switch back both the printer and the tape in the tape unit 1.

The timing in the read operation is shown in FIG. As can be seen, various impulses are available via the MPC line, which correspond to all eleven pulse generator pulses. The read flip-flop is reset on the trailing edge of any MPC pulse and set whenever a bit has been sensed from the tape. The read flip-flop reset follows the sensing of the first bit and is generated by the trailing edge of the pulse "2" from the magnetic pulse generator causes. Set the "bit detected" pulses 1, 3, 5, 7 and 8 in FIG the times of ignition of the thyratron under the control of the read flip-flop and the MPC pulses described above.

The reproduction of function characters will now be described.

The printer's function characters are "carriage return", "tabulator", "space" and "switch back". These characters are recognized by the read flip-flop and stored in the relay register like the information characters. During playback, they are checked as well as the information signs. The "D ruck" line to Relaiskontaktprüfschaltung in Fig. 29 extends from the side out on line 29.06 in FIG. 30. In the case of function sign is the change-over position of the printer without significance, and the printer keeps its previous position in U ms ehalt.

Contact 56-5 in Fig. 30 remains closed for each function symbol, and contact 53-5 toggles so that the "print" line voltage can then reach line 30.04 according to FIG. In Fig. 31 the line 30.04 leads to a relay contact 59-5. Certain of those shown in FIG Relay contacts are the decryption relay contacts for energizing the Carriage return magnets, tab magnets, or step hold magnets that are contained in box 136. The downshift magnet is shown in Fig. and is treated slightly differently than the other three functional magnets. When the printer performs the function in question, it sends in Feedback signal back to the tape unit indicating that it is going around is in progress and initiates another revolution of the belt unit. this happens generally via line 27.04 of FIG. 26, line? 6. 41, the line 41.04 again to FIG. 26 and via CB-5, whereby the circulating clutch is energized. The carriage return is similar caused by C6. The downshift function is a little different because for the Sequence of certain error correction processes two different downshift situations are provided.

According to FIG. 36, there is an encryption reset contact 73-6 and a reset contact 75-2 in the earth side of the reset magnet right and left for the tape unit. If a switch-back character is read from the tape and stored in the relay register, this leads to a switch-back operation of the printer. However, the circuits are set up in such a way that the tape unit does not switch back. The back hold magnet In the printer, via line 31.01, and in FIG. 32, it is excited by a connection to contact 73-2.

Now is the recognition of function signs that affect the tape unit, explained. ;

A transport code is read from the tape like any other character and stored in the relay register. The +48 volt voltage is generated by the Relay pyramid test circuit and routed to line 30. 04 according to FIG. In Fig. 31, the +48 volt voltage goes through toggled contact 59-5, contacts 203-4 and 50-6 and the switched contact 47-6 to line 31.06, which leads to FIG. In Fig. 27, this leads to direct excitation of transport relay 1185 held over CB-2 on line 130 in FIG will as well as through his own contact 85-4. When the transport relay Ii85 responds, the "pressure" line is interrupted and the clutch is disconnected (Fig. 26) and the relay R'34 energized. As a result of the response of relay R34 the contact '34-11 in Fig. 29 is toggled and the "character stored" relay R77 drops. This indicates that the tape unit has this mark done and ready for another character.

When recognizing eities "automatic search" codes on the tape changes the order to search. If the reference number in window 28 in the control panel 4 is the same in Fig. 3, a wind-up operation is initiated to return to the beginning of the previously selected information block.

When a search code is recognized, the relay R147 (Fig. 31) is energized and held via its own contact 147-2 in FIG. One contact 147-3 39 switches over and causes the search relay R151 to respond.

80990-1 / 0176 · = ■

A recognized stop code is deciphered in Fig. 31, where the function deciphering voltage on line 30.04 through contact 203-4, the switched relay contact 50-6 and via line 31.03 according to Fig. 26. In ' 26 causes the voltage on line 31.03 to directly energize the stop relay R80. The contact 80-8 in Fig. 26 is then switched over and the rotary clutch switched off, except when there is voltage on the in-circulation line 25.07 arises because the start button is on the control panel of the belt unit has been pressed.

An alternating code is recognized just like the other characters and in the bit register saved. The -H8 volt voltage on line 30.04 is through routed the relay contact in Fig. 31 to the changeover relay 11209 to irritate. If the relay R209 responds, the +48 volt voltage is over-extended contact 209-2 in FIG. 31 and line 31.05 according to FIG. 30. There it then arrives back via line 30.03 to FIG. 31 and via line 31.04 to FIG Fig. 27 and energizes the transport relay R85. This acts as a switch and initiates another clutch cycle in the belt unit.

According to FIG. 31, either the contact 211-8 or the contact - 214-12 is switched over, depending on whether the left or the right station has been activated beforehand. The changeover contact 209-1 in Figure 31 sends the -f 48 volt voltage to one of the "change from" relays R207 or R208 to initiate the change from one station to another. The "change from the right" or "change from the left" relay contacts are used in FIG. 24 to reverse the switching state of relays R211 and R214. A new cycle is only started when the pressure head at the new station has been brought into the position indicated by one of the pressure head switches in FIG.

809901 / Π 176 ORIGINAL INSPECTED

Then the +48 VoIt voltage comes to contact 209-3 in Figure 36 and to the transport contact 85-1 to line 36.03 and energizes the circulation clutch for the next round.

The following describes the transfer of information from a tape to the others in the tape unit.

To prepare the tape unit for a transfer operation, the mode dial 29 in Fig. 3 is set to "Transfer with Print" or "Over- %

wear with ordering "set. The switch contacts are shown in FIG. When the switch is moved to one or the other of these positions, the relay H203 in Fig. 24 responds.

"Transfer with print" means that the information on the tape is transferred to the is transmitted from the right station to the left station, and at the same time becomes a recording medium printed without being rearranged.

With "Transfer with filing", the information on the tape is saved in the transfer the right station to the belt in the left station in the same order, but the printing of the recording medium takes place accordingly the cell rearrangement conditions to be explained.

For information transfer from the tape in the right station to the tape in the left station, the reading reel 191 at the right station and the The write / erase coil of the magnetic head 96 at the left station is switched on.

The gate signal for the left station is shown in Figure 17; it is from CB-8 via contact 75-4, via contact 3-2 and the now switched contact 203-10 and via the "control left" contact 211-5 and line 17.13 derived from FIG. 21. In Fig. 21, line 17.13 controls the driver 183 and the write / erase spool on the left station. As from Fig. 17 can be seen, the now switched contact 203-7 sends a gate control signal to line 17.11 and to translation block 199 in FIG. 22, to the sensor block 195 in order to pass the bits read by the right reading coil 191 through the -Or block 196 and via line 197 to the read flip-flop. the Storage of bits in the I, e se flip-flop (FIG. 22) becomes the delay flip-flop (Fig. 2IJ shown leading line 22.04. The read flip-flop controls the delay flip-flop so that the positive edges of the Signals on the MFC line bring them into the E in state.

When a bit from the right band is recognized, the read flip-flop is brought into the on state. It is reset by the trailing edge of the next pulse that occurs on the MPC line 19.11. The ^Ä state of Lesekippstufe on line 22/4 brings the Verzögerungskippstufe in Fig. In the on state. When the read flip-flop is reset by the trailing edge of the next pulse on line 19.11, the delay flip-flop also returns to its off state. When this happens, there is a gating voltage on line 187 (FIG. 21) leading to the -and block 181. When the next pulse on the IPC line 19. II occurs after the one who has just reset the read flip-flop to complete the control of the -and block 181, an output pulse is sent to the write! , öschtreiber 182,

has previously been controlled by line 17.13, and it becomes a Bit written on the left station tape. The delay operations described above are necessary because between the reading gap the right station and the write / 1 xjsch gap at the left station there is a difference of 2.25 mm.

When the jump key 32 on the control panel 4 in Fig. 3 is pressed, speaks the relay Rl 14 in Fig. 25 on. This will make the transmission relay 1120 3 turned off in Fig. 24, and information only on the right band are skipped. Pressing the skip button will step through the band and skip characters during each Circulation, in which the jump key is pressed, a corresponding effect has a jump code in the band. -

The transmission stop code is recognized in the same way as the stop code, only one extra bit involved. This code is used to stop a transfer operation in which information from the "

B ad on the right can be transferred to the tape on the left station. During a transmission operation, just like any other character, stop codes alone are transmitted from one tape to another. The only code which can be used to stop the transmission is the transmission ■ stop code. The electrical circuits of the machine are only then for the excitation of the Stop relay R80 prepared when a transmission stop code has been recognized.

The correction method for changing the line arrangement will now be described.

net to possibly later when the line is extended by one character to be used. If more space is required for the expansion, the transport codes from several lines are used, which means that the relevant Lines need to be rewritten. In addition, during the correction operations, the carriage return revision key 47 in FIG. 4 is used instead the normal carriage return button 46 is used.

When writing the original message above, the word "various" was accidentally spelled with just "sh". In order to correct the information recorded on the tape so that the word is spelled correctly, provisions are made to correct the word using the procedures described below. It is assumed that the mode select button 29 has been set to playback for either the left or right band. The writing of the information from the tape during playback takes place under the control of the start button 26 in FIGS. 3 and 28. As mentioned, this start button 26 has five positions, namely "automatic start", "automatic", "line", " Word "and. '! Sign". With the positions "Automatic start" and "Automatic ¹¹ the tape unit for the continuous automatic

Playback of the information prepared. When the start button 26 is in the "Line" position is brought, the tape unit gives one line of information again and stops each time a carriage return code is recognized. When the start button 26 is turned to the "word" position (Fig. 31, the tape unit stops after each word is written. If the Start button 26 is brought into the "character" position, the tape unit returns only one character at a time and stops after each character. The portions of the start switch in Fig. 28 are labeled IA and IB.

Preparing the belt unit to stop in the various through the position of the start switch shown in Fig. 28 for certain situations is determined by various hot contacts assigned to the switch and are immediately to the right of the switch in FIG.

When the switches IA, IB and IC in Fig. 28 are in the "automatic start" or "automatic" position, only a stop code or a transmission stop code will stop the tape unit. If the switches are in the "line ^u" position, a stop occurs whenever a stop code / transmission stop code or a carriage return code is detected.

In the event that the word "various" has been misspelled, as indicated above, the unit is now switched to automatic playback up to the fourth line that ends with "Examples"; at this time the start button must be set to the "line" position. If the carriage return code is detected at the end of this line, the machine will brought to a stop as follows: IHne +48 volt voltage is applied across the Contact 90-.7 in Fig. 28, the now switched contact 77-11, the switch sliding contact IR, the terminal 3 of the switch IB, the Ilelais contact 59-8, the Sliding contact of switch IA, terminal 3 of switch IA, the relay contact 43-8, the Ilelais contact 50-8, the Ilelais contact 56-8, the relay contact which has now been switched as a result of the detection of the carriage return code 53-8, the line return cort act 116-9, the now switched contact 77-9 and passed through line 28.04 directly to FIG Stop relay R80 to be energized. .

Each time the start button is pressed, a certain amount of information is printed according to the setting of the start button 26. Next, the start switch 26 is now in the "word" position (FIG. 28) _; brought. Now the space following each word in the first part of the fifth line, _/ :: of the sample text causes the unit to stop.

is printed, in the present case the word "from", the button is brought into the "character" position and the tape unit now stops after recognizing each character, namely for the space following the word "from" and for the first four characters "vers" of the word "different". The circuit for stopping the unit after each character is as follows: A 448 volt voltage is excited via the switched Kentakt 90-7 (Fig. 28), the switched contact 77-11, terminal 1 of the switch IB and directly via the relay contact llß-9 and the switched relay contact 77-9 and line 28.04 the stop relay R80 A

in Fig. 26 after each revolution,

The character "c" is now entered and recorded on the tape. After inserting the additional "c", the rest of the line can be written are, namely "carried out" up to and including. This time, however not the carriage return button 46 on the printer (Fig. 4) in the usual manner pressed, but the "carriage return revision" key 47. As shown in the figure, the "carriage return revision" transfer contacts are direct connected to the slide return blocking relay R69, and the slide return transport relay R71 is bypassed so that no transport code is recorded on the tape, as would normally be the case if the Slide return button 46 would have been actuated.

With the help of the jump button 32 on the control panel 4 (Fig. 3) can from the tape read information can be completely skipped at will. How much information is skipped depends on the position of the Start switch 36 off. The spring operating modes are effective for "automatic

Most often, the jump mode is used when the start button 26 is in the "word" or "character ^11" position is. The stop process in the tape unit is set during the jump mode as well as during a printing process when the characters that are effective during the various modes appear, ie for "automatic", "line", "word" or "characters" the position of the start switch 26.

A return line switching operation will now be described.

It can happen that the tape continued to write beyond a certain line of text. In this case, pressing the Zelenrückschalttaste 35 on the control panel 4 in Fig. 3 causes the tape unit will switch back to the last recorded carriage return code. As soon as one is recognized, the tape unit stops at this point. The start switch 26 is effective in the playback mode. The return line operation is retained by pressing the return line 5-9 in Fig. 28, whereby the line return relay R1 16 is energized by the 448 volt voltage applied via the contact 66-8. This lasts via its own contact 116-4 and contact 119-3 in FIG. 28. Then the binding unit, under the control of contact 116-2 in FIG. 25, is over contact 147-1, contact 66-3 and through line 25.07 according to Fig. 26 operated, whereby the circulation clutch is energized. Switching back the The band concerned takes place under the control of the contact 116-12 in Fig.

if.

As soon as the carriage return code is now during the skid shifting and reading of the tape (R2a bit) is recognized, the contact 53-9 (Fig. 28) switches over. Then a +48 volt voltage is applied across contact 90-7, which is now toggled Contact 77-12 and contacts 53-9, 56-9, 59-9, 47-9, 40-9, 37-9, 43-9 and the now switched contact 116-11 forwarded and energizes the return stop relay Rl 19. When the relay responds R119, the line return relay R116 drops out because the relay contact 119-3 (Fig. 28) is switched. At the same time, the stop relay R80 is activated via the 28 discussed above in FIG.

The same process is indicated by a line return code on the tape triggered.

This illustrates the handling of multiple carriage return codes.

This illustrates the treatment of CR - TAB

This clarifies the treatment of hyphenated words, such as ~ for example FM transmitter or Hamburg-Harburg.

In addition, in the edge area of each line space codes are treated as carriage return characters while carriage return characters read outside the edge area as space characters be treated.

For particularly long words that appear in the margin area of a line, the slide to the very edge switched to where he was by the margin stop is stopped.

Space V characters outside the edge area are treated as space code, and carriage return characters in the edge area are also evaluated as such, namely as carriage return characters.

The left margin at character position 21 had been retained while however, the right edge from the character position 75 to the character position 57 has been changed has been. It goes without saying that the shifting of the right edge to the right, for example to the character position 85, could also be assumed will.

As in connection with the shoe 53 on the carriage 51 in FIG. 6 and the associated island sensing lever 54, bracket 55 and switch 60 and 61 has already been explained, determines the position of the margin lever 49 (Fig. 6) "

the so-called border area, which extends over about ten to thirteen characters extends. The length of the edge area corresponds to the thinge of part 53a of the shoe 53 on the carriage 51. As long as the part 53a of the shoe 53 cooperates with the edge sensing lever 54, the first switch 60 (FIG. 8) is closed held. As soon as the part 53b slides up on the lever 54, the switch 61 is closed and thus shows the end of the edge area at.

Different function characters and data characters become different recognized and trigger other processes, depending on whether they are between the left edge and the beginning of the right edge area or in the edge area perform yourself. In this description, “edge area” is understood to mean the defined area of the right line edge.

The new reproduction of the original text must be carried out accordingly the shorter available line length means that the text lines are also shorter will. For example, the hyphenated word

"Magnet-" at the end of the first line in the original text and the rest Combine "band-unit" at the beginning of the second line into a complete word without a hyphen. The same goes for several other words. On the other hand, others keep words that are already hyphenated in themselves like Hamburg-Harburg, their hyphen is also used in the compilation of the amended text. Numerous other conditions of this type are also taken into account.

The following reorganization stages occur during a reorganization process:

Reorder shortens the original lines recorded on the tape or extended, depending on the margin settings in printer 3, for the For an explanation of the rearrangement, reference is made to Figs. 45, 46, 47 and 48a to 48ni taken. 45, 46 and 47 illustrate various conditions that can occur during a rearrangement and show, in block form, like the arrangement according to the characters appearing and the others Conditions works. Figures 48a through 48m illustrate various actual situations that may arise during the rearrangement, as well as stages 1, 2, 3 or 4, which are initiated under different conditions.

A typical rearrangement is first discussed with reference to FIG. 45, at which the carriage return code is decrypted, whereby the relays involved are also mentioned. Handling of the carriage return code during A rearrangement depends first of all on whether the character is in the edge zone is located or not. ,.:

When the carriage 51 of the printer 3 is in the edge zone, i. H., when the shoe 53 is first engaged with the edge sensing lever 54 in FIG cooperates, the zone switch 60 is closed. The border area relay R108 (Fig. 38) is energized as follows. : A +48 volt voltage has been reached from line 130 (Fig. 27 °) via the Cl contact in the printer, via the, Line 27.02 to Fig. 38, where you can use the now closed zone contact 60, the now closed playback relay 141-10 and directly through the holding

and excitation coils of the relay R108 gets * Jim to excite it. If the

Carriage 51 is at the edge and a carriage return code is detected, as indicated by the "Yes" line in Fig. 45, the printer must execute the carriage return. The slide return transmission contacts in FIG. 27 close, whereby the slide return blocking relay RG9 is energized; this is maintained via its own contact 69-4 in FIG. 27. In FIG. 38 it can be seen that the "repeat carriage return or tabulation" relay R104 is energized and held by switching over the contact 69-6. When relay R104 responds, contact 104-4, ή opens

whereby the edge area relay R108 is brought to drop out and thereby indicates that the printer carriage has returned to an area outside the margin. The decryption of a tab code in the edge area results in a tabulation, whereby the slide is moved to the end of the edge area and stopped.

Becomes a carriage return or tab code outside the margin area decrypted and recognized, the processes proceed according to the path on the left in FIG. 45. By recognizing the carriage return or tab code the relay IUOl in Fig. 31 is made to respond (Mg. 45), and via the usual decryption relay contacts from line 30.04. Whenever a carriage return or tab code is outside the margin is detected, the circuit causes the printer to perform a space rather than a page tick or tab operation. In addition, an indication that a carriage return or tab code has occurred must be stored 'wef & eh. The space operation in the printer is indicated by the same +48 volt voltage on line 30.04 in FIG

809901/0175

initiated, by which the relay RlOl has been energized. This circuit goes through the now switched contact 101-3, the contact 106-04 and directly to the space magnet in the printer.

The "save carriage return or tab" relay R103 is shown in Fig. shown. It speaks of a "lock rearrangement" contact 98-1, a Contact 77-6 and the now switched contact 101-1. Relay R103 is held via its own contact 103-1 in Fig. 38. As soon as contact 103-1 switches over, the hold circuit for relay R101 "carriage return or read tab "in Fig. 38 and thereby switched off the relay R101.

In Fig. 45, the result of the blank step in the printer is another round trip the tape unit so as to cause the next character on the tape to be read. Like the arrangement after reading the next character works depends on whether it is a data character, how through the "Print" line shown in Fig. 45, or another carriage return or tab characters As indicated by the "CR« Tab "line in FIG.

If a data character to be printed is recognized, the +48 VoIt voltage is present available as usual on line 29.06 in FIG. 30; it energizes the rotation and tilt magnets in the dashed box 255 in the printer via the decryption relay contacts. Same +48 VoIt Voltage excites the "Um-" via line 30. 02 leading to FIG. *

Prevent order "-Rtlais R98. When contact 98-1 opens in Fig. 38 the relay R103 drops out and the rearrangement circuits are returned to their initial state.

If, on the other hand, another carriage return or tab code is recognized while the tape unit is rotating, the further operation of the machine depends on the status of the "carriage return or tab repeated" relay R104. Assume that this is the second carriage return or tab code that was read; therefore the relay Rl 04 does not respond now. In this case, the decision relays including relay contact 53-9 in Fig. 28 are used. _{A +48 volt voltage excites the "carriage return t} no step" via the contact 90-7 and the line 28.08 leading to FIG. VoIt voltage from line 130 in FIG. 27 via contacts C2, C5 and C6 to the now switched playback contact 90-3 and via line 27.03 according to FIG. 29. In FIG. 29, the voltage continues via the switched f

Contact 77-3 and line 29. 01 to Fig. 31, where they have a now closed Contact 102-2 energizes the carriage return magnet directly. Now the carriage return is carried out in the printer, but the tape unit does not switch any further. Therefore, the carriage return code is on the tape read a second time and the printer does another carriage return when the character is decrypted. Whenever two Carriage return codes detected on tape outside of the margin as it is after the word "can" in the first paragraph of the above

If the pattern message is the Fill, the following processes take place: Space in the printer, carriage return and again carriage return, whereby a new paragraph is added, such as the one beginning with "This clarifies" second paragraph in the sample text.

By working the printer on a carriage return, the "Slide return" blocking relay R69 in Fig. 27 is energized and relay R104 in Fig. 38 brought about the now switched contact 69-6 to respond. If a third carriage return code occurs with the Heiais 104 energized is detected on the tape, a carriage return is carried out in the printer up to the next data character that is neither a carriage return is still a tab code. If such a sign is recognized, so the "reorder inhibit" relay R98 in Fig. 24 is energized, and by the Switching the contact 98-6 in Fig. 38 causes the "repeat carriage return or tabulation" relay R104 to drop out.

What happens when a data character is recognized depends on whether it is is a hyphen or a non-hyphen character and whether the Printer is in the margin area or not. The various possible situations are based on the familiar sample text and the rest Blocks in Fig. 46. If a hyphen character is detected and relay R106 is not energized, the printer prints the hyphen, as Fig. 46 shows. If, on the other hand, a space or a hyphen has been entered beforehand has been stored by the relay R106, the further steps of the machine depend on whether the slide is inside or outside of the edge area. In the case of within the edge area, the arrangement determines whether it is switched to rearrange or not, see the diamond-shaped block labeled "Lock rearrangement". Is the machine on Rearrange switched, the rearrangement is not blocked, the machine • energizes the transport relay in the belt unit and leaves the hyphen disregarded. If rearrangement is not activated, the hyphen is printed. At the same time, the printing process causes relay R98 to respond and the Relay R106 drops out when contact 98-1 in Fig. 38 opens.

This determination is made at the beginning of the processes nsadb öer ISaatschlussiung the hyphen. The determination for hyphens is in Fig. 46, that for word hyphens in Fig. 47

Referring to the flowchart of FIG. 46, let us now look at the relay circuits involved in recognizing a syllable hyphen character! Sia * dL Referring to FIG. 30, the controls for determining whether a is printed or not are dependent on the status of the live contacts 108-2, 108-6, 108-5 and 98-4. If a hyphen is found again wfaä * , the j-j according to the previous code table is bits in the positions Ml, M2 ₀ R2a, Tl andT2.

If no space or hyphen has been saved beforehand, relay R106 is switched off. Under these conditions, mostly the impulse of the "pressure" line through the now switched contact 5S-S (Fig. 30), the switched contacts 59-12, 53-12. 4Ϊ-12, 43-12, the contact 40-12 and the normally closed contact 106-6 and by one and excite the corresponding rotation and nelgong magnets in <the dashed box 255. If the relay R106 has been energized beforehand, the contact 106- 6 (Fig. 30) switched. The current path described above ver

then passes through toggled contact 106-6 to contact 108-5. The further path of the voltage depends on the state of the all-round range relay 11108 and the "Reorganization block" relay R98. If relay R108 is not energized, indicating that the printer is operating outside the edge area, contact 108-5 will apply power to contact 98-4 in Figure 30. If relay R98 is not energized, indicating that "rearrange" is switched, the voltage is passed on via line 30.03 according to FIG. 31 and from there through line 31.04 according to FIG. 27 and M is excited

the Ti85 transport relay. If, on the other hand, relay R108 is not energized and indicates that the printer is outside the border area, but there Relay R98 energized indicating that "rearrange" is set is in progress the path through the loop described above to the rotation and tilt magnets of the printer to print the hyphen.

Consider now the relay contacts in Fig. 30 further, beginning with the Relay contact 106-6. If the edge area relay R108 is energized, what by the switching of the relay contact 108-5 and an indication that the printer is in the edge area is conditional, a voltage path runs over the now toggled contact 108-5 and the loop described above to rotate and tilt magnets in dashed box 135 energize so that the hyphen is printed.

When das.-ng.ch occurs with an I.eey ^ ohritt or hyphen Character is not a hyphen, depends on how Fit *. 46 shows how to proceed

809901/0176 'BADCRiGiNAL

the arrangement depends on whether or not the printer carriage has reached the edge area, as shown by the energization or non-energization of relay R108 in FIG. 38. If the relay ROS is not energized and thus indicates that the character has been detected outside the edge area, the character is printed by the printer 3 in the usual manner. On the other hand, when relay R108 is energized, a determination is made as to the state of relay 11106. If this is not excited, the character is printed as usual. If it is energized, there is a current path in FIG. 30 via the switched contact 108-2 and the switched contact 106-5 as well as line 30.01 according to FIG. 38 in order to trigger the "carriage return, no step" relay R102. Therefore, reading a character after the previous hyphen or a space operation in the margin area will simply result in a carriage return operation and the tape will stop without indexing so that the character can be read again after the carriage return is complete.

Reference will now be made to Fig. 47, which shows how the space or Hyphen situation is handled if it is followed by a carriage return or tab character.

Referring to Fig. 47, a character is stored in the usual manner and it is indicated that a space character has been decrypted. In this case, the blank step magnet in the printer is energized in the usual manner. In addition, when the space is recognized, the "space

3Ϊ

or hyphen "relays R100 and R106 in Fig. 38 energized sequentially. The next character is saved and a check is made to see if it is is a carriage return or a space character.

If, for example, a carriage return character is decoded after a space and rearrangement is prevented, the printer is instructed to do a Execute center return. This is done in the usual way via a Contact 98-3 and via line 30.04 in Fig. 31 to the slide return magnet. As for the blocks in the lower part of Fig. 47, if Rearrangement is switched and a carriage run 'or tabulator code is generated

is read, the procedure determines whether a space or a hyphen has been read beforehand. If a space or hyphen has been previously read, as indicated by the response of the relay R106, the circuits are such that the transport relay R85 in Fig. 27 is energized to initiate a transport step of the tape unit. The relay contacts involved are shown in FIG. 31. Whenever a carriage return or tab code is recognized, the helix R101 in Fig. 31 responds and maintains its own contact 101-2 in Fig. 38. {

At this time, the contact 101-3 in Fig. 31 is switched. Would be a before If space or hyphen code were recognized, relay would be R106 energized and the contact 106-4 in Fig. 31 has been switched. Then the function code voltage is applied on line 30.34 through the toggled contact 101-3, the switched contact 106-4 and the line 31.04 according to Fig. directs and excites the transport device R85 to take a transport step trigger in the tape unit. If the relay R106 had not been energized beforehand, the voltage on line 30.04 in FIG

8099 ni / ni7S _{6AD C} '; Ci :: al

.Jt9-

now switched contact 101-3 and the normally closed contact 106-4 directly to the Space magnet slides to cause a space in the printer.

Another criterion when reading a carriage return or tab code after a space code, the switching status "rearrange" indicates whether it is a second carriage return or tabulator character acts according to the blank step code. If this is not the case, as indicated by the switch-off state of relay R104 in Fig. 38 and relay R103 in Fig. is displayed, what to do next depends on whether the printer is in the border area or not. If the printer is not in the border area operates and the other conditions are met, the voltage on line 30.04 in Figure 31 is passed through contacts 104-5, 103-4 and 108-4 and energizes the relay RlOl. This in turn makes the work of the machine dependent on whether a blank step or a step beforehand Hyphen has been read. If no space or hyphen was read beforehand, the printer is switched one step further. If a space or hyphen code has been read, only the tape in the tape unit is advanced one step. ltet.

In Fig. 31, when the contact 108-4 is switched because the printer is switched is in the edge area, the voltage from line 30.04 is to the right to the slide return magnet and triggers a slide return. If, according to FIG. 47, relay R104 would have been energized and thus displayed would have that this would be a second carriage return or tab character a carriage return on the printer would be triggered. After a

809901/017 6

Carriage return responds to the "reorder inhibit" relay R98 in FIG. 24 and all storage conditions in the stages established by the characters previously read are turned off in preparation for new storage conditions. The response of the relay R98 depends on the printing of the first character after the carriage return. The circuit for energizing the heater 1198 over line 30.02 has already been discussed with the relay logic in FIG. 30; it depends on the switching off of the edge area relay R108, which is indicated by the fact that the contact 108-6 is in the idle state (FIG. 30).

48a to 48m show twelve sequences of operations typical of rearrangement. Reference is made to the previous description in which it is mentioned that four stages, namely stages 1, 2, 3 and 4, are established under different conditions occurring during the rearrangement.

The individual figures 48a to 48m each comprise a region having a · dashed box, the existing character and Randbereich- *

Conditions , as well as a sequence of individual operations in the tape unit and in the printer with the levels established under the various character decryption conditions and margin conditions.

Fig. 48a shows the sequence of operations that occurs when a space code is detected and the printer is outside the edge of the line. In the dashed box of Fig. 4Sa / Lst the sequence occurring on the tape is indicated as follows: character A, character B, space

809901/0176

step, character C and character D, all outside the border area. The following sequence takes place: read A, print A, read B, print B, read blank step and execute blank step, read C, print C, read D and print D. Reading the blank code results in a level 1 state, the result of which is the response of the relay R100 in FIG. The relay [1100, the space or hyphen reading relay, is also energized when a hyphen code is read. Relay R100 is held by its own contact 100-3 in Fig. 38 and a normally closed contact 106-1. Once the relay RlOO is responsive, the contact closes 100-4 in Fig. 38, and this leads to the response of the Leersehritt- or hyphenated Speicherrelai ^r R106. Relay R106 is held via its own contact 106-2. As soon as the character C is recognized and set for printing, a voltage is available on line 30.02, by means of which the rearrangement blocking relay R98 is energized. This opens contact 98-1 in Fig. 38 and the level 1 condition is ended.

Whether the arrangement is in the edge area or not, the Level 1 Be » condition is used every time a hyphen or space is stepped is encountered. According to the conditions of the stages given above, the stage-1 is reset whenever a character is printed and there is no level 4 requirement. These character recognition conditions always exist when reading a space or hyphen code outside the margin area, such as the space code between the words "this" and "is" in the first line of the sample text.

Fig. 48b shows the various processes of placing on the crane a space in the hand area. As you can see, the same occurs Sequence of characters on, but the character A is printed outside the margin area, while the action on the remaining characters is within the R-uid area occurs as shown in the dashed box in Fig. 48b.

As can be seen from FIG. 38, the closing of the edge area contact together with the toggled playback contact 141-10 during playback may trigger the relay R108, which indicates that the arrangement has entered the rearrangement area. This is because the character B has been read and is being printed and the carriage has switched to the hand area. Level 4 is then established. The voltage for energizing relay R108 is derived from line 27. 02 and via the Cl contact in the printer. After printing the character B and moving into the edge area together with the establishment of level 4, the empty ¹ step code is recognized and causes relay R100 to respond, which in turn energizes relay R106 as before. The situation now exists requires the printer to perform a carriage return f

and that the tape unit is not indexed. The reason for this is that the character C is read again after the carriage return has been carried out must work.

Referring to Figure 30, the +48 volt voltage on line 29.06 becomes the various Decryption contacts and via the now closed contact 108-2 and the now closed contact 106-5 to line 30.01 and from there to FIG. 38. In Fig. 38, the voltage energizes

400

line 30.01 the "slide return, no step" relay R102. From Fig. it can be seen that a now switched contact 102-2 is a direct excitation of the carriage return magnet as a result of the voltage the assigned line 29.01 causes.

After the carriage return operation, the level 3 condition is established (Fig. 48b) because the printer carriage has been moved to the left edge, the printer is no longer in the edge area and the character C can be read normally and printed at the beginning of the next line . The stage will be like. follows established: The carriage return transfer contact (Fig. 27) is closed by the carriage return in the printer. This in turn energizes the slide return blocking relay R69 (Fig. 27). When relay R69 responds, contact 69-6 in Fig. 38 energizes the "repeat carriage return or tabulation" relay R104. Then relay contact 104-4 (Fig. 38) opens and releases edge area relay R108, thereby removing the arrangement from the level 4 condition. However, while relays R108 and R106 _# are energized, their contacts 108-3 and 106-3, respectively, prevent the right or left forward solenoid in Fig. 36 from operating, so that the tape and tape unit remain in the same position as they were when detected of the character C were. After the carriage return, the rearrangement inhibit relay R98 (Fig. 24) is energized because the character C is read at the beginning of the next line. When relay R98 responds, the rearrangement relays are reset to their original state.

If the character strings and conditions just discussed were applied to the sample text to be rearranged, a carriage return would take place in response to the reading of a space code, for example after the word "in" at the end of the first line in the rearranged text. In the original text, however, the word "in" is followed by a space code instead of a carriage return code. However, since the space code following the word "in" occurred in the itand area of the line, as is defined by the shoe 53 on the slide 51 and the set right margin, a

both a carriage return and an empty step performed.

The string for Figure 43c is similar to that shown in Figure 48b, only occurs instead of a space code, a carriage return code. As a result of the imprint of the character B, the carriage moves into the island area and as before, level 4 is established. The subsequent reading of the carriage return code causes the carriage to return to the printer. Feedback from the printer energizes relay R6i), and contact 69-6 in Fig. 38, relay R104 energizes. The response of relay R104 causes the edge area relay R108 to drop out (Fig. 38). aside from that when the carriage moves out of the edge area, the Contact 60 in Fig. 38 is open, so that the edge area relay 11108 only then responds when the carriage moves again into the edge area. By reading and printing the character C, the level 3 condition is canceled, and all relays are reset to their original state.

With this sequence, it is unnecessary to step the tape unit prevent, since the carriage return takes place normally and before the character C is read. The reading "of the character C is under the control of the" carriage return S'jH'r relay R69 prevented. These character recognition conditions can be applied to the original sample text, in which to the word "Message" the second line is followed by a carriage return code and in which the same carriage return code after the word "message" in the third Line of rearranged text appears. The recognition of this carriage return code normally causes the carriage to return.

The situation when the carriage return code is recognized outside the edge area of the line is illustrated in Figure 48d. F.s become the same Characters as used for Fig. 48c, only these characters appear outside of the hand area. ~

If a carriage return code is detected outside of the land area, the printer must perform a blank step instead of a carriage return. It can be seen from the sequence shown in Fig. 48d that the character Λ is read and printing, that character B is read and printed, and then the carriage return code is read. Instead of a slide return however has a Level 2 situation along with "Not Level 4" which indicates that the printer is not in the edge area "is the first step to the result.

had read. Instead of a carriage return, however, the blank step is carried out, as in the sequence discussed in Figure 48d, where a level 2 condition is established. As a result of the level 2 condition together When the second carriage return or tab character is read, a carriage return operation occurs. However, the tape unit does not lead one Step out to read the second carriage return code again enable. The reason for this is that the recording of multiple carriage return or tab code indicates the beginning of a paragraph and that a carriage return must be performed regardless of whether>

the carriage return code occurred inside or outside the margin area is.

In the sequence shown in Fig. 48e, the carriage return code encountered first is converted to a space operation because it was recognized outside the edge area of the line. This is the normal procedure for handling a carriage return code encountered in this area. However, since a second carriage return code has occurred after the first carriage return code, the second carriage return code must be converted into two carriage return operations in order to determine the start of a new paragraph, for which two line switching operations are actually necessary. The second carriage return code is read twice to perform this sequence. When the second carriage return code is read for the first time, the conditions for a carriage return operation are established, but the tape unit takes no step. With the carriage return, level 3 is restored, and level 2 and level 3 conditions both remain in place until a character is printed which is in i «'i _K. 48e around. the character B is. 8ΟΠΠΠ1 / Ο176

38, the "carriage return, no step" process is replaced by the Relay 102-1 controlled, which responds under the control of contact 103-2, since a first carriage return code has been recognized, as well as a contact 104-3, which remains closed until the actual carriage return is carried out. The "carriage return, wedge, step" contact 102-1 in Fig. 36 prevents the excitation of the forward step solenoids, and * as a result, the Tape unit are in the same character position. As a result of the feedback from the printer, the carriage return blocking relay R69 responds. Contact 69-6

in Fig. 38 causes the energization of relay R104, and by the following Opening contact 104-3 becomes the "slide return, no step" magnet switched off. The "Save Slide Return or Tabular Top Code" relay However, H103 is kept in the excited state until the character B is printed; then the rearrangement blocking relay R98 responds and opens the contact 98-1, whereby the voltage is separated from this relay.

This situation of multiple carriage return codes outside the margin can be applied to the first paragraph of the sample text, where after the last Word "may" of the first paragraph two carriage return codes have been recorded. The rearranged text is thus due to the two carriage return codes the first paragraph ended after the word "can" and then a space followed by a new paragraph, according to tlem second paragraph of the rearranged sample text.

48f shows the steps that take place when several carriage return codes be found in the edge area of the line.

Reading and pressing the letter A establishes the level 4 condition. Losing »the first carriage return code results in a carriage return and the achievement of the level« 3 condition.

If it is a normal word hyphen, such as the one in Hamburg-Harburg, you do not use the Hegels for syllable hyphens when writing, but write the hyphen l ¥ i ieduin Frxli between the connected words.

In the original text, hyphens appear in the words "FM transmitter" and "Hamburg-Harburg *. The rearranged text contains the The hyphen of "FM transmitter" is outside the right margin of the Row. Printing this hyphen is done as described in this section because it is a word hyphen, not a syllable hyphen acts.

48h illustrates the treatment of reads in the margin area Hyphens. The character A is read and printed outside the margin area, and the character B is also read outside the margin area had read. The imprint of the character B, however, leads to the fact that the carriage moves into the edge area and that the relay R108 (Fig. 3R) responds to to establish a level 4 situation.

Reading the hyphen in the edge area causes the relay to respond R100 and R106 (Figure 38). Practically the same processes are now taking place

as in the sequence shown in Fig. 48b, with a space code in the "

Edge area is determined. Under the circumstances discussed here, must the hyphen should be printed and not a space step should be executed as in the sequence of FIG. 48b. A comparison between Fig. 48b and 48h shows, however, that the reading of character C is a "carriage return, no Step "process has resulted in a carriage return and no Tape step are effected so that this is now in the position to read the character C again and to print the character C at the beginning of the next Line is.

In the rearranged text, the hyphen from 'femburg-Harburg'im Edge area identified and treated according to the consequences just discussed. According to Fig. 48h the hyphen is printed, and there it is in the edge area falls, this is followed by a carriage return, but without step feed for the tape unit as preparation for reading the character ^ "H" in the second part "Harburg" the compound word.

The sequence of steps for handling a hyphen followed by a carriage return code outside the edge area is illustrated in FIG. 48i. The string is: character A, character B, hyphen, carriage return code and characters C. ·.

Referring to Fig. 48i, the character A is read and printed as usual Character B also read and printed as usual, and also the hyphen is read and printed as usual and thus the level 1 condition is established, as discussed previously. After the hyphen has been printed, the carriage return code is recognized, but since it is outside the edge area is recognized, no carriage return needs to be carried out.

Reading and printing the hyphen will set the relay as usual H106 energized. Reading the carriage return code has the response of the Relay R101 in Fig. 31 result. However, under the conditions assumed here, the printer has not moved into the edge area, and therefore relay R108 is not energized and relay contact 108-4 is in the rest position. A +48 volt voltage comes from the line 30, 04 via the now switched Relay contact 101-3 and the now switched contact 106-4

Reading the hyphen, relays R100 and 11106 are energized as before. This establishes level 1 together with level 4. After * reading and Printing the hyphen will decrypt the carriage return code and leads to a slide return as well as to the Krrichtung of level 3. Through the

With carriage return, the printer carriage is moved out of the edge area, thereby eliminating level 4. In addition, the slide return establishes level 3 via relay R69. By reading and printing the character C, all relays are returned to their original state via relay 1198. The relay contacts involved in initiating a carriage return are shown in FIG. 31. The + 4a volt voltage from line 30.04 is applied via the relay contact circuit and via contact 108-4, which is now switched over as the printer is in Liandbureich is fed directly to the carriage return magnet in the printer in order to initiate a carriage return. As a result of the carriage return, the relay RG9 responds and the contact Gö-G (Fig. 38) is switched R108 is switched off when contact 104-4 (Fig. 38} opens (

Now if the rearranged text is considered to be the original, run the sequence of steps under these «circumstances. Starting from the word part "Hamburg-" in the rearranged text has a carriage return code after the hyphen in "Hamburg-" on the tape and it would be a Carriage return must be carried out if the situation occurred in the edge area would be, according to the position of the right margin lever. if

the carriage return code but outside the range of the hand on the hyphen follows, as in the original, now as rearranged adopted text in "Hamburg-Harburg", the characters are treated as as described in connection with Fig. 4ßi.

The handling of the> ^c äbenb £ indestrichs outside of the edge area is illustrated in Fig. 48k.

While preparing the original text taking into account When evaluating these for rearrangement processes, a certain procedure must be used whenever a syllable hyphen occurs. Included the following characters must be written: I switch back, space, Hyphen. This sequence is then used by the machine as a syllable hyphen instead of being recognized as a hyphen. Since such a hyphen is generally only written when the relevant syllable is near the end of the Line, this hyphen is always followed by a carriage return code.

In the first situation to be discussed it is assumed that the characters be encountered outside of the hand area. The ones used for recording the The hyphen specified sequence would result in the hyphen according to 48k is printed directly after the character B, where it belongs, if during the subsequent creation of a printed recording medium the Bindeslrich is found in the Tland area. This is due to, that a switch back operation moves the printer back past the character B and that a space operation moves the printer back

one step forward to the next position following the character B. is brought.

The character Λ is read and printed as usual, as is the character B, and the switch back symbol causes the printer to switch back. On the other hand, the blank step character causes the printer to take a blank step, but it sets in addition, a level 1 condition, in which the relays R100 and ROG speak to. The hyphen is found after the space character, ι

but since this consequence is not recognized and the arrangement is in the Skfe-1 situation the hyphen code is converted into a transport code in the tape unit. Nothing happens in the printer. This is done as follows reached: The +4 8 volt voltage on line 29.0G in Fig. 30 passes through the decryption relay contacts in this figure and finally arrives when decoding a hyphen to contact 106-6 des Save Space or Hyphen Code relay.

In Fig. 31 the voltage on line 30.03 via line 31.04 directly excites Fig. 27 Transport relay R85 and initiates a transport step in the belt unit a. The bit combinations shown in Figure 30 for the hyphen prevent any selection of the rotation or tilt magnets in the printer. After this The next character of the transport step in the tape unit is the carriage return code encountered, which was also converted into a transport code

By reading and printing the character D and moving the carriage to the edge area, the level 4 condition is established. When reading the retention code, only the Printer instead. However, when the space code is read, it occurs an empty step in the printer and the level 1 condition, manufactured. After recognizing the space code and after executing the space, the hyphen is recognized, and there the printer has got into the edge area, the hyphen must actually be printed and not be ignored as in Fig. 48k. As a result of the recognition of the space code, the relay R106 has remained energized. As a result of Fig. 48m was the edge relay contact 108-5 (Fig. 30) in the normal closed state and caused a transport step of the tape unit. This time, however, as the slide moves into the hand area has energized the relay R108 and the contact 108-5 switched. Now there is a closed loop for applying the +48 volt voltage to the rotate and tilt magnets to select the hyphen in the printer in Fig. -30.

After the hyphen is printed, the carriage return code is recognized. This results in a carriage return, since the carriage return magnet in FIG. 31 is excited via the contact which has now been switched. If the If the carriage of the printer is moved over to the left edge, it will come out of the edge area and the level 4 condition will end. The carriage return but causes the excitation of the slide return blocking relay R69 and the Establishing the level 3 condition. When the printer moves to the left edge

809901/0176

has moved, the tape unit then leads a further tape reading ride off, and the character C is printed geiesera uad, and the rearrangement relays and «stages are returned to their original status.

Slide return codes with the following tab codes as they are in the third paragraph of the sample text will occur, according to the explanation of Fig. 48e treated "Here both the standard return" as well as the tab code in the rearranged text.

If particularly long words appear in the edge area, printing will be done of characters across the entire edge area without a space or hyphen appearing, which in the printer causes a carriage return would trigger. As soon as the printer then reaches the outermost limit of the right edge, the switch 61 is closed because the part 53b strikes against the shoe 53 of the carriage 51 in FIG and further rotates the bracket 55 and the lever 57 in FIG. 8 by a greater amount. When the switch 61 (FIG. 38) is closed, a +48 volt voltage via the now closed contact 98-5 and line 38.01 28 and then further via a contact 116-9 and a contact 77-9, which has been switched over as a result of the storage of a character, directly to line 28.04, so that the stop relay R80 in Fig. 26 responds.

To end this state in the machine, a hyphen from Hand to be keyed. However, the start button on the belt unit can also be pressed repeatedly in order to bring the carriage out of the stop area. 8 0 9 9 0 1/0176
