Description

INTERNAT. CLASS G06f

The invention relates to an electronic multiplier with a pulse generator that generates a group of pulses in one work cycle, which are placed on selected priority managers, and with a storage facility in which each priority unit counts the pulses applied to the corresponding output conductor, and the one electronic one Has transfer device that when the capacity of the associated Significance unit stores the carry over that occurs at the end of a work cycle under the control of a The pulse given by the pulse generator is transferred to the next place value unit.

Such multipliers have been proposed to let work synchronously, with the pulse generator at the end of its work cycle a emits first carry pulse, which actuates all carry devices at the same time. A second following one The pulse of the pulse generator is then used to reset the transmission devices. trouble result in such a synchronously operated multiplier with the »long Transfer «, for which special precautions must be taken. In addition, the maximum Speed of electronic parts not used.

Another suggestion is for devices that work purely in series, in which a factor in a Magnetic track is saved and the offsetting of two digits in the form of a capacitor charge takes place to discharge the capacitor by ten charge units in the event of a carry and to make a transfer device effective in the processing of the next highest digit

introduces a unit of charge into the capacitor.

The electronic multiplier according to the invention stands out from the older proposals the invention in that the delivery of the carry from the transfer device in the next higher value unit with increasing value takes place one after the other that the transfer devices trigger each other and the ίο last transfer device the pulse generator for the initiation of a new work cycle excited.

Since the transfer devices are energized sequentially, there is no problem with the long carry; since the transfer devices »5 excite each other and at the end of the transfer process trigger the impulse generator on their own, the result is an asynchronous mode of operation. using the maximum possible speed.

The multiplicand system _:

In Fig. 2, to which reference is made, the multiplicand system contains nine digit-representing, Grid-controlled gas discharge tubes with hot cathode, which are identified by the number »1«, »2«, »3«, »4«, »5«, »6«, »7«, »8« and »9« are marked. These are in their potential supply a working network so arranged that when a tube of lower value is ignited and placed in the conductive state, the remaining tubes of higher value, one at a time, in succession automatically, ending with the tube, which represents "9", can be made conductive. A positive electrical impulse if it is applied to the

. Pole 100 is applied, cause the "1" tube 101 becomes conductive. This process in turn causes that the "2" tube 102 becomes conductive and so on, to the "9" tube 103 is made conductive, after which the "carry-in" tube 104 is made conductive will. Each of these conductive tubes extinguishes almost instantly, in a way that will be described later. When the individual dial tube or tube 104 is ignited, the Potential of its cathode as a result of a resistance present in each cathode circuit more positive. This rise in potential, which is used as a positive potential pulse, is applied to an associated output conductor, such as the conductor 105 belonging to tube "1". The positive pulse from "carry-initiate" tube 104 is applied to conductor 106.

Each pulse output conductor, such as conductor 105, is connected via a rectifier, such as rectifier 107 to a point such as point 108, wherein the rectifier is directed to be positive Potential impulses, which arise at the cathode belonging to it, in the direction of point 108, but does not forward in the opposite direction. Points like point 108 and the one with the cathode the tube "2" via the rectifier 110 in connection standing point 109 are connected by a rectifier, such as rectifier in, which is directed in such a way that it generates positive potential impulses from point 108 in the direction of point 112, but does not forward in the opposite direction. Rectifiers, such as rectifiers 107 and 110, 85 are intended to have a mutual influence on the nine cathode supply systems to prevent by the generated impulses.

Anode potential is applied to the tubes in Fig. 2 from a + 115 volt voltage source 113 via resistors. stood 114 of 250 ohms, point 115, resistance 116 of 500 ohms and point 117 supplied. Of the Point 115 is across a stabilizing capacitor 118 of 0.5 microfarads coupled to earth. The anode of the "carry-in" tube 104 is in place with point 117 immediately and the anodes of the number display tubes protrude with point 117 a resistor 119 of 3500 ohms in connection.

The cathode of the "carry-in" tube is connected to ground through resistor 120 of 50,000 ohms connected in parallel with the 0.001 microfarad capacitor 121 coupled. Each cathode of the number-displaying tubes is, as shown in the "9" tube 103, on one side over a resistor of 15,000 ohms, like resistor 122, softer with a capacitor of 0.001 microfarads is connected in parallel with the earth and on the other hand via a resistor of 150,000 ohms, like resistor 125, a point like point 126, and a resistor of 3000000hm like Resistor 127, to the -150 volt conductor 124 coupled.

The control grid of each tube with the exception of the "ι" tube 101 is connected to the cathode supply network of the previous tube in the row is provided with control potential. Hence the grid 128 of the "carry-in" tube stands through resistor 129 of 500,000 ohms and point 130 to point 126 in Link. Similarly, the grid 131 of the tube "9" stands across the resistor 132 of 500 000 Ohm and the point 133 with the point '

134 in the cathode circuits of the "8" tube

135 in connection.

Every grid of a number tube, with the exception of the grid of tube "1", is represented by a point such as

Point 133, in the grid supply of tube "9" to the conductor 124, at which there is negative potential, via a capacitor of 0.001 microfarads, like capacitor 136. The grid 128 of the "carry-in" tube is through point 130 and capacitor 137 of FIG 0.001 microfarads connected to earth. These capacitors are just time regulators and prevent too rapid ignition of the tubes. It is clear that the "1" tube 101 is not a such timing device is needed because it is the first tube to ignite.

The grid of the tube "1" is thereby provided with control potential, in that it is connected by resistor 138 500 000 Ohm with point 139, which on the one hand via resistor 140 of 5 ^OOO ° ohms with the earth and on the other hand via the resistor 141 negative with the Potential leading conductor 124 is connected. ·

ao Under the given circumstances, lead: the cathode of the "1" 'tube 101 with respect to earth about - S volts, its grid in relation to earth - 25 volts and the anode in relation to earth + 115 volts. The other dial tubes in Fig. 2

as normally have the same anode potential, however, their grids have a potential of -50 volts with respect to earth. The »carry-over introduction "Tube 104 has the same grid and anode potential as tubes" 1 "to" 9 ", theirs However, the cathode is only connected to the earth because it is the last of the Is tubes which are ignited, and it is therefore unnecessary to create an arrangement that divides the potential in order to

prepare. ■

A positive potential pulse with a potential which is sufficient to cause the "1" tube ιοί to ignite is supplied to the input terminal 100 as often as a working cycle is to be caused in the pulse generator in FIG. This pulse comes from the multiplier system which is shown in FIG. 3 and will be described hereinafter. When the "ι" tube 101 is ignited and becomes conductive, the potential in the anode voltage conductor 143 drops when the cathode capacitor 142 is charged due to the resistors 114, 116 and 119 to an amount that is about 15 volts higher than the normal cathode potential, which is 5 volts amounts to. When the capacitor 142 goes into the charged state, the potential of the cathode of the tube "1" rises to a point which, through the resistors 114, 116 and 119 in the anode circuit, the potential drop of 15 volts inside the tube and at the Cathode resistors 144, 145 and 146 is determined. Therefore, the cathode of the "ι" tube 101 rises from -5 volts to about +77 volts (with respect to earth), which creates an impulse at point 108. Point 147 changes from -50 volts to approximately +1 volt. Meanwhile, the grid potential of the "2" tube 102 rises to a point at which the tube "2" ignites and becomes conductive. The potential of the anode voltage conductor drops when the cathode capacitor belonging to it is charged to about +10 volts and causes the "i" tube 101 to go out, since its anode potential falls below the cathode potential, which is temporarily at about + due to the charge on the capacitor 142 77 volts is held. In the same way the tubes "3", "4", "5", "6", "7", "8" and "9" ignite one after the other, with each tube extinguishing the previous tube in the series when ignited . Thereafter, the "carry initiate" tube 104 will ignite since its grid is connected to point 126 on the "9" tube 131 cathode circuit. This causes tube "9" to go out, as the potential at point 117 temporarily drops to about +10 volts while charging capacitor 121 in the cathode circuit of "carry-in" tube 104. It will be observed that while the number tubes "1" to "9" in their anode circuit have a resistance of 4250 ohms as a result of resistors 114, 116 and 119, only the Resistors 114 and 116 are located which give 750 ohms and between the 0.5 microfarad capacitor 118 and the anode only resistor 116 of 500 ohms. As a result, while the capacitor 121 is charging, a very strong current flows through the "carry-in" tube 104, which is suddenly reduced when the capacitor 121 is fully charged.

The inductance distributed in the circuits of this tube causes the sudden decrease of the current an oscillatory increase in the potential in the cathode, whereupon the flow of the Current in the tube stops and this goes out. Generated during this brief period of conduction however, the tube is in output conductor 106 and pole 148 (see. Fig. 6) a positive potential pulse, which a discharge of the "carry control" tube 439 (Fig. 6), the task of which will be explained.

When the number tubes of the pulse generator "1" to "9" are ignited one after the other, this will be each resulting increase in the potential of the cathode is in their associated points, like points 108 and 109, and always in one direction, namely in the direction of lie Item 112, propagated. It follows that point 108 has one pulse, point 109 two pulses, point 150 receives three pulses and so on up to point 112 which receives nine pulses. -

For each pulse receiving point a conductor, such as conductor 152, is provided which is equipped with a plurality of key switches, three in this embodiment, 153, 154 and 155. The switch 155 represents three in the one-decimal row and connects, when actuated, the conductor 152 to the output conductor 156, which represents the digit row io °. Similarly, the switch 154 represents three in the tens-decimal place row ι o ¹ and, when actuated, connects the conductor 152 to the output conductor 157, which the

Row of digits represents io ¹ . The switch 153 connects the conductor 152 to the output conductor 158, which represents the hundreds of digits ι o ² . It is therefore possible that when a key is pressed in the individual selected rows of digits, when the number tubes "1" to "9" execute a cycle by igniting them in succession, the individual output conductors receive pulses, the number of which corresponds to the value of the corresponds to the corresponding actuated key. 100,000 ohm resistors, such as resistor 159, connect each output conductor to ground to allow charge to drain from the conductor upon receipt of a pulse. A repeated actuation of the pulse generator, proceeding in cycles, results, assuming that the selected keys continue to be actuated during such cycles that the same arrangement of pulses is repeated and applied to the output poles 160, 161 and 162 (cf. FIG. 4) is transmitted. One cycle of the pulse generator corresponds to a single entry of the multiplicand factor which, through the digit row distributor in Fig. 4 to the adder in Figs. 6, 7 and 8 with the help of poles 170, 171, 172, 173 and 174 (Fig. 4, 6, 7 and 8 corresponding to the section of the multiplication process, which is determined by the section control system in Fig. 5 in, its effect on poles I, II and III (see. Fig. 4). Determined at the same time the section control system, which digit of the multiplier factor set in the keys of the multiplier system in FIG. 3 controls the repetition of the cycle in the pulse generator in FIG.

It is clear that the one on poles 160, 161 and 162 applied by igniting the tube "1" Pulse occurs at the same time (assuming a key has been pressed in each bank). The same applies to the delivery of the individual tubes. It is therefore clear that the in, the different Conductors 156, 157 and 158 pulses occurring are sent simultaneously to the adder and that the posting of information in the individual Rows of the adder can go on at the same time. Only between the individual cycles of the A pause is required for the pulse generator to allow time for a carry-over to be transmitted create.

The carry information is transferred one after the other in rows of digits in the adder, starting at the lowest row of digits. The transfer process between the cycles of the pulse generator is initiated through the "carry initiate" tube 104 (FIG. 2) which is a carry initiation pulse Via conductor 106 and pole 148 (see FIG. 6) to the row of digits io ° of the adder sends. When the transfer process is completed, a pulse is sent to pole 175 (see Fig. 3 and S) applied, which via the multiplier system in Fig. 3, a repetition of the cycle in the pulse generator (Fig. 2) caused by the fact that

_: .- a positive pulse is applied to pole 100 (Fig. 2) and brought to the grid of the "1" tube 101 via capacitor 176 of 0.00002 microfarads.

The multiplier system is therefore in constant readiness to provide a selected number of Pulses, as determined by the actuation of the multiplicand keys, to each of the output poles Output 160, 161 and 162 if on A positive pulse is applied to pole 100.

Slow down capacitors, like capacitor 177 previously described, by 0.001 microfarads the working of this impulse generator to about 10,000 impulses per second. Hence takes a cycle in which the ten tubes come to work, the time of 0.001 seconds in Claim. The adder works significantly faster. The difference in speeds is chosen on purpose so that the speed of the 'generated pulses is the recording speed of the adder does not exceed.

It will be readily understood that in the multiplicand system the number of banks of keys can be of any size without having to increase the number of tubes.

The job row distributor

As previously stated, this particular example of the invention contains three multiplicand- and three rows of multiplier digits.

In the row manifold shown in Fig. 4, the three horizontal rows of tubes provide the rows of spots of the multiplicand and the three vertical columns the three rows of digits of the multiplier Therefore the tubes 180, 183 and 186 represent the one-digit row of the multiplier, the tubes 181, 184 and 187 represent the tens digit row of the multiplier and the tubes 182, 185 and 188 the hundreds of digits of the multiplier. To simplify the designation will be these rows of ones, tens and hundreds are called Sections I, II and III, respectively.

The tubes 180, 181 and 182 represent the hundreds of digits of the multiplicand, the tubes 183rd, 184 and 185 the tens of digits of the multiplicand and the tubes 186, 187 and 188 the ones of the digits of the multiplicand. These have been designated as the digit rows io ² , io ¹ and io °, respectively.

As described, output poles are provided which represent the rows of digits io °, io ¹ , io ² , io ³ and io ⁴ and bear the numbers 170, 171, 172, 173 and 174, respectively.

A pulse that originates from the pulse generator and is applied to pole 160 is intended to to cause one of the three tubes 186, 187 and 188 to ignite, depending on which one the section control poles I, II or III is provided with the required voltage. The Pole I.

(190) provides the tubes 180, 183 and 186 with Control voltage or prepares it; the pole II

(191) prepares tubes 181, 184 and 187, and the pole III (192) prepares the tubes 182, 185 and 188 before. If the pole I (190) represents the io ° power of the multiplicand when the

the impulse; would be prepared in pole 160, then

; i; would ignite tube 186 and become conductive and thereby-emit a pulse on the diagonal output tab 193, which is in the io ° -Pol 170 ends, which is the entry point for the row of digits io ° of the adder (see FIG. 6). if

.;. instead of the pole II being prepared, the tube 187 would ignite, with the output taking place via the conductor 194, which is in connection with the pole 171, which is the input point for the row of digits io ^{1 of} the adder. If the

Each tube of the row distributor is in

'45 arranged in a circuit in such a way that it extinguishes itself when it is ignited, just as it is in connection

", -: This was explained with the" carry-in "tube 104 (Fig. 2). All tubes connected to the same diagonal output conductor have the same cathode circuits. The cathode of tube 186 is up on the

... resistor 198 of 50 000 ohms, with which capacitor 199 of 0.0005 microfarads in parallel connected to earth. Further, the cathode is through capacitor 200 of FIG g, oi microfarad with the output pole 170

It is similar with the cathodes of tubes 183 and 187, which are connected to earth by resistance 201 and the capacitor 202 parallel to it connected to earth and through the capacitor

,: r 203 ⁰ can be coupled to pole 171. The other cathode connections are similar and are as follows: the cathodes of tubes 180, 184 and 188 are connected to ground through resistor 203 and capacitor 204 and coupled to terminal 172 through capacitor 205; the cathodes of tubes 181 and 185 are connected to the '^; Ground connected by resistor 206 and capacitor 207 and coupled to pole 173 by capacitor 208, and tube 182 is connected to ground by resistor 209 and capacitor 210 and to pole 174 by capacitor 211 ^:! couples.

The anodes of all the tubes in a horizontal row are supplied from the same pole. So z. B. the anodes of the tubes 180, 181 and 182 with a potential of +75 volts'"* from the source 212 via resistor 213 'of 250 ohms, point 214 and resistor 215 of 500 ohms.'

-. The grids of all tubes, since they get their potential from the section control system in Fig. 5, normally have a strong control potential, in this way the tubes 180, 183 and ^: - 186 (Fig. 4) get their grid potential from the pole l ( 190) (see Fig. 5); the tubes 181, 184 and 187 get their grid potential from pole 191, and the tubes 182, 185 and 188 get their grid potential from pole 192 / This grid potential is normally -80 volts, but is, in preparation State reduced to -35 volts / If e.g. B. Under normal circumstances, section I of the multiplication process occurs, the pole 190 changes from -80 volts to -35 volts negative. This ^: \ change is applied to the grids of tubes 180, 183 and 186 via a resistance of ^{5 to} 500,000 ohms, such as resistor 219, a point, such as point 220, and a resistance of 500000hm, such as resistor 221. Points, like point 220, are linked with the associated · input line. Thus point 220 is coupled to conductor 222 through a capacitor 223 of 0.00002 microfarads. If via one of the poles 160, 161 and 162 with the prepared '. State of the pole 190 a pulse signal is received, the corresponding tubes i8o ^,! 183 or 186 ignite and extinguish themselves, each ignition of a tube emitting a pulse to an associated output conductor. The poles I, If " and III are prepared in sequence by the section control system. Each of them remains in the prepared state until the pulse

generator works as often as the value of the corresponding actuated multiplier key switch is equivalent to.

Section control

The section control shown in FIG

, ■■■. includes a start (start) tube 250 and three section control tubes I, II and III, which are provided with the numbers 251, 252 and 253, respectively are.

The cathode of the starting tube 250 is connected to the earth via the resistor 254 of 50,000 ohms Link. Your grid is made by the resistance

255 of 50,000 ohms connected to points 256 and 257. The point 257 is on the one hand on the Resistor 258 of 500,000 ohms, conductor 259 with a negative potential of 150 volts, and on the other hand through resistor 260 of 350,000 ohms, point 261, resistor 262

ao of 5000 Ohm, point 263, resistor 264 of 2500hm in connection with the start button switch 265, which when closing makes contact with pole 266 for positive potential (+115 volts) manufactures. The point 263 is determined by the stabilization

a5 setting capacitor 267 of 0.5 microfarads and point

256 coupled to ground through the 0.01 microfarad capacitor 268. When the capacitor 26S charges when the button 265 is closed, the negative voltage is drawn from the grid of the starting tube 250 removed, igniting the tube and increasing the potential of its cathode. This Voltage rise is caused by capacitor 271 from 0.00005 microfarads to point 270 transfer. The anodes of tubes 251, 252 and 253 receive their potential from point 263 via the resistor 272 of 3000 ohms. During the slight delay of perhaps 0.001 seconds, during the ignition of the starting tube 250, the potential supply network of the tubes I (251), II (252) and III (253) stabilized; likewise the control voltages which the grids of the tubes of the row distributor in FIG. 4 through poles 190, 191 and 192. The cathode each of the tubes I, II and III is on the one hand over a resistance of 150000hm, like resistance 273, and the parallel capacitor of 0.002 microfarads, like capacitor 274, which with a resistance of 1000 ohms, like resistor 275, is connected in series with the earth and on the other hand via a resistance of 100,000 ohms, such as resistor 276, a point,

. like point 277, as well as a resistor like resistor 278, with the -150 volt conductor 259 in Link. The grid of the tube I (251) is across the resistor 280 of 50,000 ohms, the Point 270 and resistor 281 of 500,000 ohms in connection with point 282, which through resistor 283 of 50,000 ohms to earth and through resistor 284 of 250,000 ohms

• 60 is connected to the —150 volt conductor 259. The grid of the tube II (252) is connected to the point 277 and receives its control potential from this. When the tube, I (251) is in the conductive state, this point will assume a higher potential, so that a positive potential pulse, which is applied to the conductor 285, is connected to the grids of the tubes II and III via a capacitor , such as capacitor 286, of 0.00002 microfarads which connects to point 287 in the grid circuit of tube II which will ignite tube II and not tube III. The normal grid potential of tubes II and III with respect to the cathode is approximately -80 volts. When it is prepared due to the conduction in the previous tube, it will be about -35 volts. The ignition pulses applied to input conductor 285 are adapted to ignite only one prepared tube. Therefore, the sequential operation of the section control system in Fig. 5 begins with the ignition of the starting tube 250. After a short interval during which the supply networks adapt themselves, the tube I ignites and becomes conductive. This process, as has been explained, causes the potential of the cathode of tube I to rise, thereby preparing the grid of tube II. This preparation potential is also applied via point 288 and conductor 289 to pole 190 (cf. FIG. 4), which prepares the grid of column Γ of the tubes of the row distributor 180, 183 and 186 (FIG. 4). The increase in potential in the cathode of the section I tube 251 (FIG. 5) is also passed on, through conductor 290 to pole 291 (see FIG. 3), in order to operate the cycle of the multiplier system. At the end of a cycle of the multiplier system, a positive potential signal is applied to pole 292 (see FIGS. 3 and 4) under the control of one of the rows of keys The consequence is that the I-tube 25i is extinguished, since the potential of its anode falls when the capacitor 293 of the cathode of the tube II is charged, while the capacitor 274 is discharged at the same time. The ignition of tube II (252) also causes the potential at poles 191 and 294 to rise, thereby priming tubes 181, 184 and 187 (Fig. 4) of the row distributor, and causes a duty cycle of the multiplier unit under control to begin the keys in the row of digits io ¹ . At the end of this cycle of the multiplier io ¹ , the pole 292 (FIGS. 3 and 5) receives a further potential pulse which causes: the ignition of the section III control tube 253 (FIG. 5), the extinction of the section II control tube 252 , the preparation of pole III (192) which affects the tubes 182, 185 and 188 (FIG. 4) of the row manifold. It also causes a potential increase at pole 295 (FIGS. 5 and 3) in order to initiate a working cycle of the multiplier ^{unit under the control of the keys in the row io 2.} At the end of cycle io ^{2 of} the multiplier unit in FIG. 3, a pulse is applied to pole 292

created, which remains ineffective; there is no

;. ^{: there are} further section tubes that can be ignited. At this point the multiplication process is complete, the start button can be opened and the button switches of the multiplier and multiplicand system can be used.

'■,' can be returned to their inoperative position. It should be noted that the last impulse at pin 292 can be used to have some means of automatically resetting the keys to control, namely by setting up a tube, which after the Section III control tube ignites and z. B. can operate an electromagnet.

ao The multiplier system shown in Fig. 3 comprises nine number tubes "i", "2", "3", "4", "5", "6", "7", "8" and "9" , which have the numbers 300, 301, 302, 303, 304, 305 306, 307 and 308, as well as a relay tube 9, which is used to generate a pulse to take a step in the operation of the section control system on the way via pole 292 effect, two delay tubes 310 and 311, which regulate the delivery of the pulses on pole 100, which cause the repetition of the cycles in the multiplicand system, as well as three banks of digits with nine digit key switches, which represent the rows of units, tens and hundreds of decimal places which for the sake of simplicity is referred to under io °, io ¹ and io ² rows of digits. When multiplying, the multiplier factor is set by closing a key switch in each selected bank. The multiplier system operates in cycles, with each bank of keys controlling the operation of the dial tubes during one of the cycles by determining which of the nine dial tubes will begin operating a cycle and therefore how many tubes will operate in that cycle . The dial tubes are connected to operate in sequence, one at a time, toward tube "9" in response to pulses received from the grids of all tubes collectively via conductor 320 sent from the last transfer control tube 321 (Fig. 8) originate and are applied to the pole 175. In this way, the transmission cycle takes place after the multiplicand factor has been booked in the adder. At the end of the transmission cycle, a pulse in pole 175 causes a step in the operation of the tubes of the multiplier system. Consequently, the number of tubes that work in a single digit series cycle of the multiplier system determines how often the multiplicand factor is booked into the adder. In which row of digits of the adder it is booked is determined by the row of digits distributor, which is controlled by the section control system together with the multiplier system / in order to bring the multiplication process into line with the row of digits of the multiplier system that controls. If you z. If, for example, you want to multiply by 5, the "5" key322 in the io ° part row is pressed, the "o" keys 340 and 341 in banks io ¹ and io ² are pressed, the multiplicand factor is set, and the start key 265 (Fig. 5) is closed. The tubes 180, 183 ^: and 186 (Fig. 4) of the row distributor are prepared, and a positive potential pulse is applied to the pole 291 (Figs. 5 and 3), which is generated by the rectifier 323 (Fig. 3), which is passed through the Resistor 324 of 500,000 ohms is shunted and through the capacitor 325 of 0.01 microfarads, the conductor 299 to initiate the section and the key switch 322 to the point 326 in the grid circuit of the tube "5" (304) is temporarily conducted, the normal Eliminates control potential and ignites it and puts it in a conductive state. The cathode potential supply circuit provided for the tube 304 contains a resistance of 15,000 ohms which causes a sudden increase in the cathode potential of the tube. This is passed through conductor 327 and capacitor 328 go from 0.001 microfarads to the common multiplier output conductor 329 at point 330 and from there via capacitor 331 from 0.0002 microfarads to cause delay tube 310 to ignite, which in turn delay tube 311 to ignite, which emits a positive potential pulse via its cathode to the pole 100 to cause a cycle of the multiplicand system and to enter the multiplicand in the adder under the control of the section I tubes and the row distributor. At the end of the entry of the multiplicand, the transfer cycle takes place in the adder, and at the end of the transfer cycle a pulse is applied to pole 175 (FIGS. 8 and 3). This pulse is generated by individual capacitors, such as capacitor 332 of 0.00005 MikiOfarads. transferred to the grid circuits of all nine tubes of the multiplier system. Each grid of these tubes has a normal / 110 control potential, which is reduced to close to the ignition point if the dial tube of the next lower value is in a conductive state. Therefore this preparation has the effect that the positive potential pulse in conductor 320 causes tube "6" (305) to ignite, to the exclusion of all other dial tubes of the multiplier system. This makes a positive ^; Caused a potential pulse in the conductor 329, which causes a cycle of the multiplicand system and also causes an increase in the potential of the cathodes of all the dial tubes, since these are all coupled to the conductor 329. The cathode of the conductive tube "5" is located within an area that is 15 volts away from the anode potential. The additional increase

of the .potential,: which was caused by the ignition of the tube,. ,, "6", causes the current to flow through the tube "5", which means that "it goes out. This process is repeated, The tubes "7", "8" and "9" ignite in succession and result in a total of five cycles ₍ , "of the multiplicand work, which corresponds to the value of the pressed key" 5 "(322). The conductive state in the tube "9" (308) prepares relay tube 309 by passing some of the increase in cathode potential through point ,,, 333, resistor 334, point 335, resistor 336, and conductor 337 to the grid circuit of tube 309. The grid The tube 309 is also connected to the conductor 32o _v via a capacitor 338 of 0.00005 microfarads. When a pulse is received at pole 175, the relay tube 309 becomes, while the tube "9" (308) 'is in a conductive state , ignited, the tube "9" to extinguish,. Bring a positive potential limpulse ,. which emanates from its cathode, pass on via the conductor 339 to pole 292 (see Fig. 5) to cause the section II control tube 252 (Fig. 5) to ignite and the section I control tube to go out. As a result, a pulse is applied to the pole 294 (Fig. 3 and 5), .... which, .by the actuated »Οκ key switch 340 and from.da via point 335, resistor 336 and conductor 337 is forwarded to the Bring relay tube 309 to ignite. It follows that there is no operation in the multiplicand system and the section control system is operated to ignite the section III tube 253 (FIG. 5). Thereby, a _pulse: on pole 295 (Figure 3 and 5.) Is applied which, as the "oe-button switch 341 is closed again immediately .... the relay tube 309 brings to ignite. The process is now over and the multiplicand has been entered five times in the adder. If the "o" -Tastenschalters would have been 341 key "8" (342) operated in the job number io ² ... the multiplier system in the just cited example in place, then had the last to pin 295 emp _v captured pulse tube "2" (301) ignited, and as a result the multiplicand system would have been set in motion. and the, _v multiplicand factor would have been posted to the adder under the control of the Section III tubes of the row distributor. Such an entry of the multiplicand would be made because each of the tubes "2", "3", "4", "5", "6", "7",. , "8" and "9" of the multiplier system in sequence and then the relay tube would be ignited, whereby the process would be ended. The relay tube 309 is arranged in such a circuit that it; after it has become conductive ... extinguishes itself. . _; ·., ,,,: ■■■.

The tube 310, when it has passed into the conductive state, is made to extinguish by the ignition of the tube 311, and the tube 311 causes itself to be extinguished, as can be seen .... _; when the circuits and circuit elements of Fig. 3 are detailed.

All anodes of the tubes "1" up to and including "9" are supplied with a positive potential of 115 volts because they are connected to the conductor 350, which through the resistor 351 of 3500 ohms, point 352, resistor 353 of 500 ohms, point 354 and resistor 355 of 250 ohms is connected to the source (356) of positive potential (+115 volts). The anode of tube "9" receives potential from point 352. Point 354 is coupled to earth through a stabilizing. · ■■■: capacitor 357 of 0.5 microfarads. The cathode of each dial tube is on the one hand across a resistance of 15,000 ohms, such as resistor 358, which belongs to tube "4", and on the other hand across a resistance of;. 100,000 ohms, like resistor 360, a point, like point 361, and a resistance of 100,000 ohms, like resistor 362, with the supply conductor 359 for negative potential (-150 volts) in connection. This gives _each,:; Cathode has a normal potential of -10 volts, which rises to +80 volts when the tube is conductive. Points like point 361 provide the grid potential for the following tube. This is normally -80 volts and rises to -35 volts when the ..:, tube belonging to it is in a conductive state. The points, such as point 361, are connected to the grid of the following tube via a resistance of 250,000 ohms, such as resistor 363, a point, such as point 326, a resistance of 250,000 ohms, such as resistor 364, a point, such as point 365 , as well as a resistor of 50000 ohms, such as resistor 366, in connection. The tube 309. which produces the impulses that bring the section control system to work, draws its anode potential from point 352 .. Its cathode is above the. Resistor 367 of 50,000 ohms and the parallel capacitor 368 of 0.0005 microfarads to earth and via resistor 369 of 650,000 ohms to the conductor for negative potential 359. The grid of the tube 309 draws its potential through the resistor 336 of 50,000 ohms and the resistor 334 of 250,000 ohms from the point 333 in the negative branch of the cathode .-.:. Circuit of the tube "9". With the circuit values just given, when tube 309 becomes conductive it will self-extinguish and when ignited will emit a pulse through conductor 339. The aforementioned delay tubes 310 and 311 are arranged in such a way that when one of the number tubes "1" through "9" is ignited they ignite in succession, the ignition of tube 311 producing a positive potential pulse in pole 100 around the pulse generator urge to work too! The task of the subsequent delay is to allow the potentials in the section control and distribution system to stabilize after a row switchover. You refer to the anode of the tube 310; Potential across resistor 371 of 3500 ohms, resistor 372 of 500 ohms, point 373 and resistor 374 of .250 \ ohms; _ which with

one pole for the supply with positive potential, (+115 volts) is connected. The point 373 is coupled to earth with the help of the 3750 capacitor of 0.5 microfarads. The cathode of the Tube 310 is on the one hand via the resistor 375 of 15,000 ohms and the condensate parallel to it

, .. sator 376 of 0.001 microfarads with the earth and on the other hand via resistor 377 of 150,000 ohms, point 378, resistor 379 of 300,000 ohms and point 380 connected to a source of negative potential of 150 volts, 387. The grid of tube 310 draws its normal control potential through resistor 381 of 50,000 ohms, point 382, resistor 383 of 500 OQO ohms and point 384, which on the one hand through resistor 385 of 50,000 ohms to earth and on the other hand through resistor 386 of 250,000 ohms is connected to the point 380, which is connected to the negative pole 387

ao (-150 volts) leads. When the tube 310 is received a pulse through capacitor 331 to. Ignite is brought, is the result Increase in the potential of the cathode through resistor 377, point 378 and resistor 388 of 500,000 ohms after charging the delay capacitor 389 of 0.001 microfarads, which couples point 390 to earth, applied to the grid of tube 311. The anode supply for tube 311 is taken from point 391, and the cathode is through the resistor 392 of 50,000 ohms and the parallel ones

_; . 0.002 microfarads capacitor 393 coupled to ground. When the tube 311 is ignited, the tube 310 is extinguished as a result of the drop in the potential of its anode, and the tube 311 sends a pulse to the pulse generator 100

The adder

There are six banks of digits in the adder

... : intended. The ones or io ° bank and the tens or io ^ bank are shown in Fig. 6, the hundreds or io ² bank and the thousands or io ^s bank are shown in Fig. 7 and the tens ^{or io 4} - Bank and the hundreds of thousands or

, _ ■■ io ⁵ banks are shown in FIG. There are ten dial tubes in each bank. In the drawings the tubes for the digits 8, 7, 6, 5, 4 and 3 have been omitted in each bank, e.g. For example, indicated in Fig. 6 by the dashed lines 400, since the tubes and circuits are merely repeated in their arrangement compared to the others which are shown in detail in each bank. It is clear that the number of tubes in a bank can be increased at will

_(.. .. or can be scaled down in order and the purposes of another number system to meet to be able to every job row bench include a Übertragerröhrc "Γ" and a carry control tube "7" C, "which-for the implementation of Stellen-

j, .- · ensure the transmission of a transfer statement. _Ί As the one-bank io ° is typical, it is described as a pattern for all banks as far as the ring of the number tube is concerned. Anode voltage of +115 volts is supplied from pole source 401 via resistor 402 of 250 ohms, point 403 and resistor 404 of 7500 ohms, as well as conductor 405, to which all anodes are directly connected. The cathode of each tube is connected to earth via a resistance of 15,000 ohms, such as resistor 406, and the parallel capacitor of 0.002 microfarads, such as capacitor 407, * and a point, via a resistance of 100,000 ohms, such as resistor 409, like point 410, and a resistor of 100,000 ohms like resistor 411 connected to a negative supply conductor 408 which '^; is supplied with -150 volts. Points such as point 410 are connected to the grid of the subsequent tube of the ring via a resistance of 500,000 ohms, such as resistor 412, a point such as point 413, and a resistance of 50,000 ohms, such as resistor 414. Points, such as point 413, are each coupled through a capacitor of 0.00002 microfarads, such as capacitor 415, to an input conductor 417 common to the row of digits. A switch / <like switch 416 is installed between the earth and the grid of each "o" tube, which works in such a way that when it is briefly closed, it ignites the tube "o" and makes it conductive. When a tube becomes conductive, it prepares the grid of the tube next in the ring, since the potential of the cathode of a conductive tube rises. The reduced control potential in the following tube makes it more susceptible to a positive input pulse on conductor 417 than any other tube in the ring. The circuit values specified for the relay tubes of the row distributor have the effect that their output in the form of impulses only ignites a prepared tube of the adding "" ■ plant and not an unprepared one; The conductor 420 closes the row ring by connecting the preparation point 421 for the cathode of the tube "o" with the preparation point 422 of the tube "1". The potential ^; of the anode supply conductor will temporarily drop as the cathode capacitor of one conductive tube charges while the capacitor associated with the cathode of the preceding preparatory tube discharges. This has the consequence that · ■■ -: the anode potential at the previous tube is temporarily interrupted and this causes it to go out. In this way, a number of pulses applied to the output conductor '417 will sequentially ignite the same number of tubes in the ring,' and the conductive tube represents the accumulated indication. The indication can be read by viewing the ignition of the tubes " observes or senses their condition electromechanically. '

It is arranged so that a '423 transmitter tube will ignite every time the tube "o" ignites and thereby read a full duty cycle of the ring indicates. This transmission tube will later become the

809 522/5

Brought to extinction, in order to create an impulse,

. _ which one step in the operation in the ring the next higher row of digits. Switches, like switch 108, in the anode supply of each Γ-tubes are opened before the zero switch is closed to ignite the

r T-tubes to prevent. After the whole When adder has been set to zero, switches such as switch 418 are closed.

Input conductor 417 receives pulses from Pol 170, which is the output point for the digit row io ° from the digit row distributor (FIG. 4).

The transmitter tube 423 draws its anode potential from the + 135 volt pole 425 via switch »5 418, resistor 426 of 250 ohms, point 427 and the resistor 428 of 7500 ohms. Point 427 is made by capacitor 429 of 0.1 microfarads coupled with the earth. Tube 423 draws its cathode potential from the fact that it passes through the ao resistor 430 of 10 000 ohms connected to earth. The grid of the tube 423 refers to it Potential in that it is through the resistor 431 of 50,000 ohms, the point 432 and the resistor 433 of 500,000 ohms with point 434 in Veras connection, which on the one hand via resistance 435 of 50,000 ohms to earth and on the other hand via resistor 436 of 250,000 ohms to the - 150 volt conductor 408 is connected. the The transmitter tube is therefore usually in non-conductive state, but is caused by a positive pulse which is applied to the cathode of the "O" tube 437 when the tube "o" is ignited is put into a conductive state. This impulse will applied to grid potential point 432 through capacitor 438 of 0.00005 microfarads.

At the beginning of a transmission cycle, which is initiated by a positive potential pulse received at pole 148 leading to the grid of carry control tube 439 the tube 439 ignited. When this tube becomes conductive, the potential of it rises Cathode. This increase is propagated through capacitor 440 by 0.01 microfarads and applied to the cathode of the transmitter tube 423. If the tube 423 is in the conductive state, it is made to go out by this pulse from tube 439, with the potential of its Anode rises suddenly and the said positive pulse through the capacitor 441 of 0.0005 microfarads and rectifier 442 which is oriented to be positive , Forwards impulses to the input line for the next higher position bank.

The rectifier 442 is shunted through the resistor 443 of 50,000 ohms. If, therefore, the bank position row has passed zero during a: <cycle of the pulse generator, the transmitter tube 423 will be ignited, whereupon at the end of the cycle of the pulse generator the carry control tube 439 will ignite and extinguish the tube which generates the transmission pulse the next higher row transmits and causes the addition of a unit in this. The carry control tube 439 draws its anode potential from the -l-115-VOlt source 445, namely via the resistor 446 of 2500hm, point 447 and the resistor 448 of 4000 Ohm. Point 447 is coupled to earth through capacitor 449 ″ of 0.1 microfarads. The cathode of tube 439 draws its potential from being connected to the Ground is connected to the -150 volt source 451 through 150,000 ohms resistor 452, point 453 and 300,000 ohms resistor 454. Point 453 is coupled to ground through 0.002 microfarads delay capacitor 455. The grid the tube 439 draws its normal control potential via the resistor 456 of 50,000 ohms, point 457 and the resistor 458 of 500,000 ohms, which is connected to the point 459, on the one hand via resistor 460 of 50,000 ohms to earth and on the other hand the resistor 461 of 250,000 ohms is connected to the negative supply pole 451. The point 457 is connected to the pole 148 through the capacitor 462 of 0.00005 microfarads Eiselemente ignites the transfer control tube 439 when a positive pulse is received at pole 148 and immediately afterwards extinguishes itself, while in the meantime it has sent out a positive pulse via the capacitor 44 ° to extinguish the transfer tube if it is was in the conductive state and causes the carry unit to be added in the next higher row of digits. The increase in the potential at point 453 resulting from the ignition of the tube 439 is passed to the grid of the transfer control tube 470 of the bank io ¹ after the capacitor 455 has been charged, in order to cause it to ignite. The point 453 is the grid ^{potential point:} for the tube 470. The tube 470 is equipped with the same potentials and circuits as the tube 439 and, when ignited, causes the transmitter tube for bank io ¹ to go out, which if it was in a conductive state , via the pole 471 (see. Fig. 7) forwards ^{a pulse to the data line of the bank io 2.} Firing the carry control tube 470 for bank io ^{1 also} passes a pulse through pole 472 to fire the carry control tube for bank io ² . The input conductor 473 of the row bank io ¹ contains a rectifier 474, which passes positive potentials only in the direction of the arrow in order to prevent the absorption of positive pulses by the current circuits of the row distributor, which are generated when the transformer tube of the iao the next lower row of digits is made to go out. Such a rectifier is provided in every row except the lowest one. Each rectifier, like rectifier 474, is shunted by a resistor of 50,000 ohms, like resistor «5 475. The output signal of the

Transmitter tube from <ler row of digits io ³ goes via pole 476 (see Fig. 8), the output signal from the

; v Carry-over control tube of digit row io ³ leads over

Pole 477 ... · ....

The digit bank io ⁵ (Fig. 8), which only has the purpose of ^{receiving overflowing information and only receives impulses from the digit bank io 4} , via point 493 and rectifier 501, has the capacitor 502 of 0 as an appendix to its input circuit, 0005 microfarads, resistor 503 of 50,000 ohms, rectifier 504 and resistor 505 of 50,000 ohms to excite the circuit elements attached to the lower row banks by virtue of their connection to the row distribution system.

The transfer tube is intended to show how other "overflow" banks of digits can be added to the adder or

ao how a signal can be made to indicate a full adder.

The output from the transmitter tube of digit row io ⁵ is indicated by the dashed line 490 (Fig. 8) to indicate how over-

«5 carryings carried out in the higher rows can be.

The transmitter tube 510 is in a self-extinguishing circuit arranged and draws anode potential of +75 volts from source 511, via resistor 512 of 250 ohms, point 513 and resistor 514 of 500 ohms. Of the Point 513 is through capacitor 515 of 0.1 microfarads coupled to earth. The cathode is connected to earth via resistor 516 of 50,000 ohms and the parallel capacitor 517 of 0.0005 microfarads in connection.

The delivery of positive pulses from the carry control tube 321 of the last row leads via pole 175 to the multiplier system (Fig. 3), as already mentioned, by one step move forward.

When the row of digits io ⁵ passes zero, a signal appears in conductor 490 which can be used to indicate an overflow of information.

The circuit elements of the adder have been chosen so that this pulses with a Can absorb speed, which is twice as high as the speed with which the Pulses are generated by the pulse generator.

Way of working

With reference to FIGS. 1 is now the Operation in the multiplier summarized.

The adder is set to zero by pressing the zeroing buttons in all rows of the adder after the anode potential has been temporarily removed from the transmitter tubes. As an example of a task, 658 is selected as the multiplicand factor and 123 as the multiplier factor. These factors are set on the relevant buttons, and the start button is closed (Fig. 5), which causes the starter tube to ignite. After a short delay, the section I control tube is made to ignite, which prepares column I of the row distribution tubes and sends an impulse to the io ° input of the> multiplier system (Fig. 3), which via the key switch »3« is directed to cause the tube "7" of the multiplier system to ignite. The ignition of tube "7" causes the two delay tubes to ignite one after the other. The one that ignites last sends a pulse via pole 100 (see FIG. 2) to the multiplicand system in order to cause the nine digit tubes to ignite one after the other. As a result of this process, eight pulses are sent to pole 160, five pulses to pole 161 and six pulses to pole 162 (see FIG. 4) and go from there to the row distributor, which transfers eight pulses to the bank via pole 170 (see Fig. 6), five pulses via pole 171 and six pulses via pole 172 (see Fig. 7) and brings the adder to work accordingly. Thereafter, the carry lead tube (Fig. 2) is made to ignite, which sends out a pulse via the pole 148 (see Fig. 6) to cause the carry control tube 439 of the io ° bank of the adder to go ignite. The transfer control tubes are ignited in series, and the associated transfer tubes, if any of them are in a conductive state, are thereby extinguished in series. It is clear that no tube is in a conductive state after the first booking. The carry control tube of the row of digits io ^{5 of} the adder (Fig. 8) forwards a pulse via pole 175 (cf. Fig. 3), which causes the prepared tubes "8" 100 of the multiplier system to ignite. After the ignition of the two delay tubes, a pulse is sent via pole 100, which causes a further working cycle of the pulse generator in order to book the number 658, as previously described, into the adder. Since no transmission has taken place so far, the number 206 is in the adder. After the ^{digit row rings io ° i:} and ι o ^{2 of} the adder have passed zero and the ring io ^{2 is} at zero, the transmitter tubes of the digit row rings ίο ⁰ , ιό ¹ and io ^{2 of} the adder in the conductive state. When the transfer control tubes work in sequence, the transfer tube io ° is first brought to extinction, which ^{books a unit in the row io 1} , so that the adder is set to 216. ^{Then the carry control tube io 1} ignites, the transfer tube is made to go out and sends a unit to the ^{digit row ring io 2} , so that the setting iao of the adder 316 is. Finally, the carry-over control tube is brought io ² for igniting that io ² brings the Übertragerröhre void and a unit on the site array ring ι o ^s transmits, so that there is selected as the reading adder 1316 which is the sum of 658

plus 658 represents. The number 658 is posted again in Section I: due to the ignition of the tube "9" of the multiplier system, to which the adder 1974 shows. The end of the transmitter tube cycle sends another pulse via pole 175 to the multiplier system. This time _{t; v} ignites the section control switchover tube (Fig. 3) and sends a pulse via pole 292 (see Fig. 5), which ignites section II tube 252 and extinguishes section I tube, the section II column of the row of digits. Distribution system prepared and transmits an impulse to pole 294, which goes to the ioi key bank of the multiplier system. Since key "2" has been pressed in this, the tube "8" is accordingly ignited, the delay tubes are set to - ignite and then the multiplicand system is put into operation so that they have the same arrangement of pulses, which represent "658", ao sends to the job row distributor. At this point the tubes of Section II column;,; of the digit row distributor is prepared, and the pulses are accordingly assigned to digit rows io ¹ , io ² and io ^{3 of} the adder. After the section II bookings have been made twice, the section control system changes to section III, in which the rows of digits io ² , io ³ and io ^{4 of} the adder are activated, but the booking of the multiplicand factor is only made once, since the io ² digit of the multiplier factor is 1. Now, ·., The multiplying process is complete. The final firing of the section control switch tube 309 (Fig. 3) has no effect on the section control tubes in Fig. 5 since the HI tube 253 does not prepare any more tube. The start button can now be opened: .- ,. whereupon all tubes, with the exception of those that are in the adding unit and represent the information product, will be in the extinguished state. Now the device is ready for another multiplication process,; .. ·; which can be carried out with or without resetting the adder to zero.

It is clear that the key switches of the multiplier and multiplicand system in some way according to the well-known

,,,: drive to the automatic setting of factors can be controlled.
