Description

Recording head on writing measuring devices The invention relates on a recording head on writing measuring devices with depending on the Signals from a first signal source for recording trajectories over a writing surface moving writing element, which via electromagnetic devices with identification signals supplying signal sources and for recording additional Identification marks is set up along the course of the trajectory.

With regard to the numerous designs of fixed facilities, which is used nowadays in the training of airborne and seafaring personnel there is a need for a permanent record of the activity of students while using the training device in question. Through this Both teachers and students can check such a record in the same way to recognize, discuss, avoid etc. the mistakes made, and make this possible an increase in the performance of the students and at the same time the highest possible utilization of the training device. The need for permanent record is added those training devices particularly clear, in which the student in the course of a given task has to perform a variety of different actions. There is there are currently many chart recorders or devices for recording diagrams; none however, this device automatically plays back the many different events, which the student has to bring about in the course of solving a problem. This can be best illustrated by an example. In one of the flight training devices you can train the entire crew of a bomber plane, with the pilot and the copilot the aircraft under all foreseeable conditions and emergencies during a given flight, steer the gunner at pre-empted targets have to shoot and the bombardier drop his bombs on pretended targets Has. A common task with this type of training equipment would be at startup begin and end with the landing, and the instructor or instructor would normally pose a large number of subtasks and changes to the given conditions, an instant solution on the part of the crew members concerned require. A pictorial record of each such mock flight of the aircraft would have to keep track of the aircraft, the points at which a Enemy contact occurs, the times of the firing of the on-board weapon and the bombing and other measures taken by the crew members at any time reveal. As already mentioned, devices that write continuously are used for Graphical course recording is available, but is available with all of these Devices required, the special events occurring during the task to manually enter into the diagram what is unreliable, an amount of labor requires and regularly leads to errors.

There are also registration devices known in which markings can be controlled automatically by the events to be marked, except by hand. It is particularly a matter of attaching identification markings the registration curve itself with the help of electromagnetic actuators. Furthermore, already registering measuring instruments are known in which the Writing organ by electromagnetic means in a selective manner to generate various Operating states of characterizing features can be deflected onto the recording medium is.

The aim of the invention is to achieve the object of applying a very large number of different types of identification markings along the registration curve, taking into account the respective course of the registration curve. According to the invention, a number of separately operable electromagnets arranged one above the other, each cooperating with an armature, each of which is mechanically connected to the writing element via a rod arrangement, and a sound device, through the actuation of which each of the electromagnets can be connected to the signal sources delivering the identification signals, are provided, in such a way that the writing element can be deflected from its central position into one or more settings in accordance with the identification signal. In this case, devices can be provided by means of which, in accordance with the direction of the trajectory, only those electromagnets can be excited, through whose action identification markings are recorded in the form of lines intersecting the trajectory.

The linkage can be a pen, which is mounted on several pivot bearings on a linkage supporting plate and a linkage on each of the anchors have, one end of which is arranged in each case on a projection of an anchor is and the other end of which rests against the plate, so that this is when the relevant electromagnet by an identification signal to at least one of the pivot bearings is pivotable. The number of electromagnets can be equal to the number of pivot bearings be.

The rod member carrying the pen can expediently be arranged coaxially with the electromagnet arranged above. Farther can be arranged separately a second group of electromagnets, and the axes the two electromagnet groups can be parallel to each other and perpendicular to the plane run along the plate. The armature of the second group of electromagnets can over a linkage mechanically connected to the plate arranged above the first group stand.

The pivot bearings on the underside of the plate can be symmetrical to each other be arranged, and the pivoting linkage on the plate can rest on points between the pivot positions.

A switching device can be provided which operates on one of two simultaneously occurring identification signals responds in such a way that at least one electromagnet is turned off and a second is turned on, so that the pen for marking the simultaneous occurrence of two identification signals in a predetermined one Direction is adjusted. The switching device can respond to one of the identification signals respond so that at least one other electromagnet is excited and that the Pen is deflected one after the other in the same direction. It can also a switching device can be provided which responds to at least one of the identification signals responds so that the excitation of at least one electromagnet by another Identification signal is prevented.

The linkage of the two groups of electromagnets can be designed in this way be that one group holds the pen perpendicular to the direction of deflection distracted by the other group. The electromagnets can advantageously be ring-shaped.

Appropriately, the recording head can be on one in two on top of each other perpendicular directions movable carriage be arranged. Here you can electrically conductive members may be provided which run in grooves in the carriage.

The invention is also in fields other than education useful e.g. B. in technology, agriculture, etc., where it is necessary to promote the business, to maintain better stability and facilitate mutual Relationship between the occurrence of a multiplicity of events Allocate messages or information of various types to one another. The invention creates hence a recorder for registering a large number of events.

The invention is explained with reference to the drawings. Two exemplary embodiments of the invention are shown in the drawings. F i g. 1 is a view of a registration system in which a transparent surface for receiving the records, each with a recording device on both sides of this surface is shown, F i g. 2 shows a perspective view of the internal components of an exemplary embodiment of the recording device according to the invention, FIG. 3 shows an example of a diagram of the recording device, FIG . 4 shows a vertical section through the recording device, FIG. 5 shows a view of the recording device from below, FIG. 6 shows a perspective illustration of a second exemplary embodiment of the invention, FIG. 7 shows another example of a diagram produced by the recorder, FIG . 8 shows an example of an electrical circuit used in connection with the present invention, and FIG. 9 a and 9 b an example of an electrical circuit which makes it possible to obtain a large number of records of events automatically.

In Fig. 1 is the application of the invention on the two devices 6 illustrates for registering events whose one each located on both sides of a recording disk. 2 The recording plate 2 is preferably made of a transparent material, as it is known for example under the trade name "Lucite", which makes it possible to make recordings simultaneously on the front and on the back of the plate. B. illustrates the course of the training aircraft and their others the course of the enemy aircraft. Each of these recording devices 6 is mounted on a carriage 4 assigned to it in such a way that a pen 8 which protrudes from one end of the recording device 6 comes into contact with the surface of the recording plate 2 at the point indicated by 10. The recorder 6 shown on the right in the figure records on the side of the mounting plate facing the viewer of the figure and therefore appears in a view from above, while the recorder 6 to the left records on the side of the plate facing away from the viewer and therefore appears in a view from below. The registration devices 6 are known by suitable means, e.g. B. the rope or belt pulley 60 (in Fig. 5), vertically movable along the carriage 4, and in a similar manner, the carriages 4 are movable in the horizontal direction with similar means across the surface. It should be noted that every course of the aircraft can be broken down into a horizontal component x and a vertical component y . These individual components are transmitted to the recorder in such a way that the horizontal components x move the carriage 4 practically over the surface of the plate 2 and the vertical components cause the recorder 6 to be driven along the carriage. The pen 8 then flawlessly draws the resultant of these two components, which corresponds to the course of the aircraft. An example of a continuous graph is in solid lines at 9 in FIG. 3 shown.

The invention is not satisfied with the technique of recording a continuous graph, but goes even further in that, as shown in FIG . 3 , which enables instant recording of special events. In Fig. 3 shows a diagram which also shows the recording of various messages by instantly entering individual markings. The embodiment of the invention illustrated here is e.g. B. arranged to make the following markings: (a) a vertical half line 11 below the line, (b) a vertical half line 12 above the line, (c) a vertical line in full length 13, (d) a horizontal half line 14 to the left of of the line, (e) a horizontal half-stroke 15 to the right of the line, (f) a horizontal stroke 16 of full length, or (g) compound marks. Each of these markings can be used to record one of the particular events of the type enumerated above, e.g. B. the bombing, the firing of guns, the dropping of flares, etc., can be used. From the further description and from FIG. 7 it can be seen that markings at an angle of 45 'or another selected angle relative to the horizontal or vertical can also be carried out with the recording device according to the invention.

As can be seen from the schematic representation of the inner parts of one embodiment of the invention in FIG. 2, the recording device 6, which is accommodated in a housing 18 ( FIG. 4), is equipped with a container 20 from which the pen can be fed by a known feed device, e.g. B. a rubber hose 22, ink is continuously supplied, which arrives there on the surface of the recording plate 2 for application. A flexible member, e.g. B. a leaf spring 24, which is attached to the underside of the housing 18 , has a bracket 26 attached to its lower surface for supporting an intermediate point of the pen outside the housing.

Within the housing 18 , in the preferred embodiment of the invention, five electromagnetic devices, e.g. B. field coils 28, housed for moving the pen, which are arranged in two groups, rows or stacks each coaxially and at a distance from each other and of which the left stack for moving the pen 8 in its longitudinal direction and that of the right stack for moving the Serve pin in its transverse direction. Between each pair of the annular coils 28 there is a movable horizontal member, such as an annular plate or armature 30. Each of these armatures 30 has a protrusion or tongue 32 for receiving the lower end of a vertical rod or member 34. The upper ones free ends of the rods 34 connected to the left coil stack 28 press against the lower surface of a horizontal member, e.g. B. a movable disc 36 attached to the top of a second vertical shaft or bracket 38. The support or shaft 38 extends axially through the annular coils 28 and armatures 30 of the left stack and protrudes beyond the housing. The lower projecting end of the rod 38 is attached to the pen 8 by known means, e.g. B. an inverted U-shaped clamp 40 articulated.

The toroidal coils 28 and armatures 30 of the second set or group shown in FIG. 2 is shown on the right, are connected to the movable disk 36 by means of a transmission device suitable for transmitting torques. This device for transmitting torques is equipped with rods 34 which are connected to the tongues 32 of the armature 30 in a manner similar to that described above. The upper free end of each of the rods 34 is attached to an assigned torsion arm 42 which is, in turn, each fixed to a horizontal torsion shaft 44 that is transversely extending in the housing and fixed below the movable plate 36 at a assigned similar torsion 43rd

Like F i g. 4 shows, the arrangement described above is enclosed in the housing 18. To prevent excessive deflection of the stylus to prevent 8, above the movable disc 36 damping devices, such. B. four equally spaced shock absorbers 46 (only one of which is shown), mounted so that the end of the movable members of the shock absorbers 46 against the upper surface of the movable disc 36 is applied. Each anchor 30 has a protrusion, e.g. B. od a rivet 48. The same, which is attached to the underside of the armature 30 at a point on the circumference of the same, which is opposite the tongue 32 , so that the armature is held at a distance from the underlying coil.

The housing 18 has a recess 50 ( FIG. 4) for receiving the carriage 4 which carries the recording device 6 in question. The carriage 4 is of U-shaped cross-section and has an electrically non-conductive insert with a number of grooves 52 in the underside thereof. In these grooves 52 electrically conductive members 54 are inserted, through which the recorded event messages are transmitted from some external source to the housing, where they are touched by contact members, e.g. B. brushes 56, which are in constant contact with the electrically conductive members 54. The message is then fed via lines to the relevant electromagnetic devices 28 and causes the relevant event to be recorded in the form of a marker in the manner described below.

The movable disc 36 is preferably supported with its underside on four pivot points or points 58 a, 58 b, 58 c and 58 d . These support points can be projections on the lower part 59a of the frame 59 rigidly connected to the housing, or, as in the preferred embodiment, projections on the disc 36, which are arranged symmetrically around the circumference of the movable disc (F i g. 2).

In the preferred embodiment, the two coil groups are arranged so that their axes lie in a plane parallel to the longitudinal axis of the pen 8 , and the pivot points 58 are arranged at the corners of an imaginary square, the sides of which are parallel or perpendicular to the longitudinal axis of the pen 8 . It is obvious that the two groups of electromagnets, preferably with the exception of the lower electromagnet which carries the bracket 26 and the linkage connected to them, are rotatable with respect to the axial shaft or support 38 and the pen 8 in such a way that the intended Square, in the corners of which the pivot points are located, no longer lies at right angles (with its sides parallel or at right angles) with respect to the longitudinal axis of the pen. In this way it would be possible to implement the steps shown in FIG. 3 to make markings 11 to 16 shown rotated by any arbitrarily selected angle relative to the horizontal or vertical. The relationship between the torsion shaft 44 and the pivot points would remain the same in this modified form. It will also be apparent that the preferred embodiment could be modified such that only three pivot points are provided on disk 36 so that only one electromagnet would be required in the right group (FIG. 2). With such an arrangement (see FIG. 6) , however, the number of types of markings that can be produced with the aid of the pen would be reduced. The pivot points would then be arranged in the corners of an imaginary triangle and the two torsion bars 34 of the left group would be connected to the midpoints of two sides of the triangle and the torsion shaft 44 of the right group would be connected to the midpoint of the third side of the triangle. In this way, only one point would be used in creating a given mark. In the embodiment according to FIG. 6 holding members 61, preferably three pieces, are provided, which are arranged evenly distributed around the circumference of the disk 36. These retaining members consist of downwardly projecting lugs on the frame 59 and give the disc 36 lateral support and prevent the disc from jumping out of its axial position during operation.

From Fig. 2 and 6 it can also be seen that all or parts of the electromagnets 28 may be stacked around the shaft 38 so that the torsion bar 42 and 43 and the transmission rods 44 are omitted, provided that there is sufficient vertical space.

The above-mentioned pulley 60 is attached to the lower side of the recorder 6 ( Fig. 5) , and a second such pulley, not shown, is located on the upper side. These two rope disks cause the recorder to move up and down on the carriage 4. As already described, the pen 8 is carried by the bracket 26 , which in turn is attached to the flexible member 24, and this is fastened to the housing 18 by means of any suitable fastening means 62 .

The normal mode of operation of the recording device 6 is shown in FIG. 1 and 3 can be seen. The ones in the lower left corner of FIG. 3 confirming curve 9 indicates the flight path of the aircraft when flying to the east. This curve comes about in that the carriage 4 is moved from left to right over the mounting plate 2, while the recording device 6 maintains a fixed position with respect to the carriage 4. When the aircraft turns to the northeast, the carriage 4 continues its movement from left to right across the plate 2, but the recorder 6 simultaneously travels from the bottom upwards along the carriage 4, and with these simultaneous movements the one under 450 arises against the horizontal inclined portion of the curve 9. When the aircraft is heading north, the carriage 4 stops moving in the transverse direction over the plate 2 and the recorder 6 continues to move along the carriage 4 from bottom to top only, so that the vertical section of the curve 9 shown is produced.

The mode of operation of this embodiment of a recording device is best shown in FIG. 2 can be seen. The general mode of operation is based on the fact that one of the ring coils 28 is excited in accordance with a message signal received from an external transmitter. This input signal, which is generated when an event to be registered occurs, is referred to below as the intermittently occurring input signal. The excited coil attracts the armature 30 adjacent to it and lifts it together with the rod 34 attached to its tongue 32. As it moves vertically, the rod 34 pushes the movable disk 36 upwards, and it pivots about the pivot points 58 furthest away from the rod 34. When the movable disk 36 is raised, the shaft 38 is also moved upwards because it is attached to the movable one Disc is rigidly attached, and with it the pen attached to this shaft is lifted. It should be noted that when the rod 34 pushes the movable disk 36 upward, that movable disk has the normal tendency to evade the thrust so that normally no effect would be obtained except that the shaft 38 may be appreciably bent. The pivot points or bearing tips 58 are therefore inserted into small recesses provided in the frame 59 for receiving them, thus ensuring that the movable disc is properly pivotable and secured against sliding and that the shaft 38 moves in the intended direction instead of just bending.

To record the in FIG. The markings shown in FIG. 3 require four toroidal coils and four armatures and consequently also four rods, with the aid of which four different markings can be generated when the four coils are excited independently of one another. It is readily apparent that a full-length vertical or horizontal line consists of two half-lines produced one after the other. In order to produce four markings, the pen 8 must therefore be movable from its position 10 ( shown in full lines in the lower left corner of FIG. 2) to four positions indicated by the broken lines 10a, 10b, 10c and 10d and this requires the movable disk 36 to be movable in four directions. If one considers the in F i g. 2 parts shown on the left, it can be seen that this is achieved in the following way. When the uppermost toroidal coil 28 attracts the armature 30 below it, the rod 34 is brought to abut the movable disc 36 , and this is pivoted about the pivot bearing tips 58 a and 58 b , with the result that the shaft 38 and the Pen 8 are moved to position 10 d , the horizontal half-line 15 being created to the right of the curve. When the next lower toroidal coil 28 is excited, the armature 30 below it is raised, the rod 34 is brought to abut the movable disk 36 , the disk is pivoted about the pivot bearing tips 58 c and 58 d and consequently the shaft 38 and the pen 8 in brought the position 10 a , the horizontal half line 14 arises on the left side of the curve.

The remaining markings are activated by energizing the in F i g. 2 ring coils shown on the right are generated. When the upper toroidal coil 28 is energized, the armature 30 immediately below it is raised, the rod 34 (as shown in full lines) causes the torsion arm 42, the horizontal torsion shaft 44 and the torsion arm 43 under the movable disc 36 in FIG to rotate counterclockwise direction indicated by an arrow, which has the consequence that the movable disc is pivoted on the pivot bearing tips 58 a and 58 c, so that the shaft 38 and dei pen 8 are moved into the position 10 c, whereby the below the curve lying, vertical half line 13 is generated. When the next lower toroidal coil 28 of the right group is energized, the armature 30 below is raised, the rod 34 (partially invisible in the figure) is caused to move the torsion arm 42, the horizontal torsion shaft 44 and the torsion arm 43 below the movable disc 36 to pivot in the clockwise direction indicated by an arrow, which results in a pivoting of the movable disc about the pivot bearing tips 58 b and 58 d , in which the shaft 38 and the pen 8 are moved into the position 10 b and the vertical half line 12 arises above the curve.

If a full line is to be generated, the coils concerned are energized one after the other, and this has the consequence that two half lines are generated one after the other, which together result in the full length line. It goes without saying that a simultaneous excitation of the coils concerned, so z. B. the coils for the production of the markings 12 and 13, does not lead to the fact that a mark is generated, since in this case the forces acting on the pen are equal and opposite to one another. It is readily apparent, however, that when the coils to produce the markings 12 and 14 are energized at the same time, the pen produces a mark at an angle of about 45 ', as will be explained in detail below. The different markings that can be generated by exciting individual coils and by exciting several coils at the same time are more clearly shown in FIG. 7 can be seen. Thus, the marking 80 is produced in that the two coils used to produce the markings 11 and 15 are excited simultaneously, while in the case of the marking 81 the coils for producing the markings 12 and 14 are actuated. If the marks are generated in sequence immediately 80 and 81, results in the marker 82. The simultaneous excitation of the coils for the marks 12 and 15 leads to the marking 83 while a simultaneous excitation of the coils for the marking 11 and 14 to the marker 84 leads. The successive production of the markings 83 and 84 results in the mark 85.

Some of the various combinations of markings are in the sloping portion of the curve of FIG. 7 shown. More complicated markings using various combinations are also possible if the drawing speed is slow enough.

In order to ensure that each armature 30 is attracted by the ring coil 28 assigned to it, a projection, e.g. B. in the form of a rivet 48 is used. In this way, the armatures 30 cannot lie flat on the toroidal coil below, since the rivet 48 ensures that an air gap is maintained below the armature, with the result that the magnetic lines of force pass through the armature so that it is attracted when the toroid in question is energized. - It is to be noted that, as already mentioned, above the movable plate 36 and in contact with said damping means such. B. buffer cylinder 46 are mounted, so that a dead gear of the movable disc after execution of a half stroke (half stroke) is avoided. The number of buffer cylinders 46 provided is preferably equal to the total number of directions in which the movable disc 36 is pivotable, and these buffer cylinders should be located midway between adjacent pivot bearing tips 58 opposite the rods 34 and on the outer edge of the movable disc. The buffer cylinders 46 also have the advantage that they provide the necessary return force for returning the armature 30 to their rest position when the excitation of the toroidal coils 28 ceases. If one of the toroidal coils 28 is excited, the armature 30 adjacent to it is attracted by the coil, so that it, the rod 34 and the movable disc 36 are raised, the disc 36 abuts against the buffer 46 located above the relevant rod and this squeezes. When the toroidal coil 28 is thrown off, the only force acting on the portions is that of the compressed buffer 46 which acts on the movable disc 36 and rod 34 and causes the armature to be forced back away from the toroidal coil.

Another advantage of the invention is that the device is also able to provide a discontinuous or intermittent track. This type of recording (track diagram) is required when it is desired to synchronize one or two diagrams od to make them comparable with each other. The like. Generally speaking, this may be achieved by reacting the same time all the pens by their receiving surfaces so that there are short gaps on the diagram itself. This is achieved in the embodiment described here in that an additional ring coil 28 is provided in the housing 18 , which is arranged on the bottom of the housing 18 in close proximity to the flexible member 24 on which the pen 8 is attached. This additional ring coil 28 (the lowest in the left group in FIGS. 2 and 4) is excited in the same way as described above, attracts the flexible member 24 and thus lifts the bracket 26 and with it the pen 8 . F i g. 2 and 4 show the pen 8 in its raised or upper position from the plate. In order to ensure that the pen 8 returns to the drawing surface, an elastic or loading member, e.g. B. a spring 64 is provided which is attached to the shaft 38 and engages the pen.

F i g. 8 illustrates the simplest circuit for operating the embodiment of FIG. 2. In this case, a common voltage source via manually operable switch 90 to 94 with one of the electromagnets is connected to a to e. The left part of FIG. 8 indicates the marking that is drawn with the pen or spring when the individual switches are closed. Thus, when switches 90 and 91 are closed at the same time, an input signal is generated which is not registered by a marking, while when switches 90 and 92 are closed at the same time, a line inclined to the right at 45 'is drawn under the curve. The simultaneous closing and opening of switches 90 and 93 causes the pen to draw a mark under 45 'to the right above the line. Other markings that can be easily generated are markings inclined to the left at 45 'above and below the curve and various combinations of these markings, as shown in FIG. 7 are shown.

In Fig. 9 a and 9 b is an example of a circuit for automatically energizing any individual electromagnet and for energizing several electromagnets at the same time or one after the other to produce a variety of simple and composite markings on the curve. This example applies to an arrangement with two pens according to FIG. 1 , can, however, as can be recognized by a person skilled in the art, also be used when using an arrangement with only one pen. Instead of the pens, the five electromagnets of groups 1 and 11 are shown in the diagram.

An intermittent input signal or pulse generated when a certain event occurs in a generator 100 , which may be either momentary or permanent, travels through the diode 101, through the winding 102 of the relay D, to earth. Relay D actuates arms 103 and 104 in response to such a pulse. Arm 104 disconnects a 28 V power source from contact 105, while Aim 103 disconnects a capacitor 106 through arm 103, contact 107 and the winding of relay E connects with earth. The pulse moves arm 108 to contact contact 109 and arm 110, which is connected to a 28 V power source, away from contact 111 to contact 112. In this way, via line 113, the winding of relay F is energized set. When the condition of the voltage in winding D ceases, arm 104 returns to its normal position and connects a source of 28 volts through a time delay resistor 114, through arm 108, causing capacitor 106 to reconnect. In this way, the arm 110 is used to generate a voltage pulse in the line 113 of a certain duration, which is independent of the duration of the original current impulse at the relay D and is determined exclusively by the resistance of the relay E and the charge on the capacitor 106 . When the relay F is energized, it connects a current source via the arm 115 and the contact 116 to a contact 117 which, in the normal position shown, is connected to the electromagnet which causes the pen to make a vertical mark below the graph curve. The line 118 leads this voltage pulse to the arm 118 a of the relay L, which in its normal position shown is not connected to any working circuit part, but if the relay L is excited by one of the other pulse sources v or u via the line 119 , has a connection of the arm 115 with the contact 116 has the consequence that both the pen 1 and the pen II produce a mark below the graph curve. This is an example of the recording of an event that is relevant to both of the graph curves drawn by Pens 1 and II.

When relay G is energized, it brings arm 117 connected to line 116 into contact with contact 120, which would result in the formation of a mark on the left hand side of the graph. The relay G is automatically energized by the controller 200 when the direction of the graph curve is between ± 451 and between 135 and 225 ' from the vertical (north). This eliminates the possibility of a marking being drawn that coincides with the graph curve and is therefore indistinguishable from it.

The second event h generates an intermittent input signal or a voltage pulse in the device 121, and this has the consequence that the relay B, which has similar contacts to the relay D described above and in which a capacitor 122 across the winding of a relay C discharges turns off the charging voltage source of the capacitor 122 and connects it to the contact 124 and the arm 125 via a resistor 123. The capacitor 122 actuates the relay C and applies a voltage pulse to the line 138 . The relay arm 125 of the relay C is moved down and charges a second capacitor 126 . After a predetermined charging time, namely the discharging time of the capacitor 122, the arm 125 is released and moves against the contact 127, so that the capacitor 126 is discharged via the contact 127, the diode 128 and via the winding of the relay D. While capacitor 126 is being charged, relay H is energized via line 138 , and the capacitor 140 connected to it energizes relay F. For event h, relay J operates earlier than relay F, which operates via diode 128 , relays D and E and line 113 from capacitor 126 is energized.

Relay J moves arm 146 away from contact 143, thereby disconnecting a line 144 connected to power source 145 which is energized when an event r occurs. The contact arm 150, which is connected to a source of 28 volts, is brought into contact with a contact 151 , thereby energizing the line 153 which is connected to the arm 154 of the relay L and to the arm 152 of the relay G. Arm 152 is normally connected to the "step-up" coil for pen 1 via the top contact.

The events v and u generate input signals or voltage pulses in the generators 160 and 161, respectively. The generator 160 is a pulse generator, while the pulse generator 161 supplies the differentiating circuit with a constant voltage so that the leading edge of the constant voltage is converted into a current surge. The pulse from pulse generator 160 is provided on conductor 163 and to delay circuit 250 which provides a second pulse on line 163 which is delayed in time from the first. Similarly, the Verzögerungssehaltung 251 provides a second pulse from the source 161 into the conduit 163. In this manner, the same relay by a supplied on line 163 pulse from the pulse generator 160 or from the pulse generator 161 are operated, and v is the impact of events and u is therefore described at the same time.

A voltage pulse on line 163 is passed through diode 164 and energizes relays B, C, D, E and F in the same way as a pulse from generator 121 for event h. Line 163 is also connected to common terminal 133 and a voltage pulse appearing at this point will energize not only relay A but also relay L. When relay A is energized, arm 132 will contact the Contact 137 moved down. The capacitor 130, which is up. then charged by a voltage source via the circuit 131 is now connected to the common terminal 133 , so that the relays A and L are kept under voltage until the capacitor is discharged. In this way, the relays A and L are energized twice, the first time by the introductory voltage pulse from the generators 160, 161 and then, a certain period of time later, which is determined by the time constants of the delay circuits 250 and 251 , by one second voltage pulse.

When relay L is energized, arm 154 is moved downward into contact with contact 164 which is connected to arm 155 of relay M by lead 165 and normally energizes the "upstroke" electrics of pen II by pulling connects the voltage source of 28 volts connected to the contact arm 150 of the relay J to the contact arm 155 via the line 153, the contact arm 154, the contact 164 and the line 165 . It should be noted that relays H and 1 have been energized via line 138 from the relay B and C circuit as described.

The upper arm 118 a of the relay L is moved downwards to contact the contact 156 , which is connected to the arm 157 of the relay M via the line 166. The arm 157 is normally connected to the "smear" electromagnet of the pen II. The delays in the illustrated circuits are chosen so that the pen 11 first executes the stroke and then the stroke. Furthermore, since the delay circuits 250 and 251 cause a second pulse, the marking drawn by the pen 11 as a result of the events u and 1 consists of a double up and down stroke on the diagram. The relay M can be actuated by means of the control device 201, explained in detail below, which determines the direction of the diagram and actuates the relay M (similar to G) when the direction of the curve is between ± 45 'and between 135 and 2251 against the north direction on the Drawing board lies.

The lower section of the composite marking just described is generated by the arm 118 a, which is connected to the contact 116 of the relay F via the line 118. As already mentioned, the relay F comes into operation a certain period of time later than the relays L and J.

When a pulse is generated by the generator 162 as a result of an event t, a voltage pulse is applied to the line 136 which is connected to the arm 134 of the relay A. When relay A is at rest, arm 134 is connected to contact 135 , which is connected via line 170 to the "lift-off" electromagnet of pen II. When the relay A is energized by the events v or u, the arm 134 is lifted from the contact 135 so that when the pen is in its lifted position, it is fed onto the drawing surface to carry out the marking in question. In this way the occurrence of the more important events u and v is always recorded.

The occurrence of an event s causes the generator 171 to operate and send an interrupt input signal or a voltage pulse through the line 138 to operate the relays H and J. The event s thus results in a downstroke of the pen I by bringing the arm 150 into contact with the contact 151 , thereby energizing the line 153 and the arm 152 of the relay G , and this results in the downstroke. Since the relay L is not energized, there is no other marking.

When an event r occurs, the generator 145 is activated, which applies an intermittent input signal or a voltage pulse to # the line 144 and normally to the contacts 143 and 175 . In the idle state, the contact 143 is connected to the arm 146, the line 147 and the arm 148 of the relay F via the contact 149 to the lifting electromagnet of the pen 1. In this way, the event r results in the generation of a dashed line on the pen 1 when the relay J is not energized. The relay J is energized by the events h, v, u and s . So if an event r occurs at the same time as an event h, v, u and s, it would normally not be able to be registered. However, this is remedied in that a contact 175 is connected to the line 144. When relay J is actuated in such a way that it disconnects the lift-off circuit of pen 1, which would normally register the occurrence of event r by a dashed line, arm 176 is connected to contact 175 , and any voltage pulse that occurs as a result of the The occurrence of an event r occurs in line 144, is fed through line 177 to contacts 178 and 179 of relay G. The contact 179 is disconnected from its actuating arm 180 in the idle state, while the contact 178 is normally used for the illustrated position of the relay G, i. H. in the event that the curve is inclined towards the north axis (y-axis) of the drawing surface at an angle between 45 and 1350 and between 225 and 315 ' , with which Ann 1.81 is connected. The arm 181 is connected to the electromagnet of the pen 1 for the right deflection. In this way, the simultaneous occurrence of an event r and an event h, u, s or v has the consequence that the electromagnets of the pen I are excited for upstroke and right deflection, and this results in a mark under 45 'on the diagram. When relay G is energized, the pulse as a result of an event h, v, u, or s passes from arm 152 to contact 182 and gives a "right stroke" while arm 180 is now connected to contact 179 , so that as a result of the event r a voltage is applied to the "upstroke" magnet, and this results in a 45 'upward and rightward inclined line. From the above operating examples it will be apparent that those skilled in the art can create other circuits similar to those described to achieve markings at 45 'to the top left, bottom left, bottom right, or combinations of these markings as well as composite markings using these elemental markings . It can also be seen that, although the description only expressly refers to angles of 45 ', the use of an embodiment according to FIG. 6 also gives the possibility of creating markings at other angles. It is also possible to use an angle on one drawing surface and a second angle on the other drawing surface, so that it is possible to assign the events to the associated diagram with ease.

The board contains a summary of the events that followed these events energized relays and the various achieved thereby Markings for the preferred embodiment.

The registration device 6 is shown in FIG. 9 b indicated by broken lines and is driven by means of a mechanical connection 202, which the in F i g. 5 belong to pulleys 60 shown , which move the recording device 6 in the “north-south” direction (vertical) along the carriage 4. The carriage 4 is movable in the "east-west" direction (horizontally) by means of a mechanical drive 203 to which the pulleys 204 belong. The pulleys 60 and 204 are each driven by a motor 205 for the “north-south” direction and a motor 206 for the “east-west” direction. The motors 205 and 206 are activated by a dismantling device 207 which is responsive to a continuous input from a speed calculator 208 for actuating the motors 205 and 206 . The course wave 209, the position of which is determined by a course computer 252 , actuates a cam switch in the control device 201 which energizes the relay M when the course direction moves within the prescribed limits given above. Similar devices and drive means can be provided for energizing the relay M and / or the relay G.
