The marked synchronous operation is practically inevitable. Ss nung »+« means »impulse«, the designation These deviations result, for example, from »-« means »no impulse«. The six combinations of a shifted starting position of the switching arm or position impulses allow a choice from 64 communication groups in the reduction gear between motor and combination groups.

Using FIG. 2, the mode of operation of a ripple control receiver with preselection is described. Via lines 1 and 2 connected to the electrical supply network, the ripple control pulses are sent to an input filter 3. A to this ^c . Connected relay 4 is excited by the received Rundstcuerimpulse and closes a switch. As a result, a synchronous motor6 is connected to the voltage PO of the network. If a pulse has the length of the start pulse s, then does the motor 6 set a cam switch? around which it maintains voltage for the duration of a ripple control program. The synchronous motor 6 drives a switching arm 8 of the synchronous selector and a pulse comparison device 9.

The switching arm 8 slides during a broadcast program over fifty contacts, for example, the number of which is determined by the number of pulse times of the program given is. The first six contacts are not provided with connections, as the corresponding Pulses for the preselection are intended. Two of the following contacts can be connected to one Changeover switch to be connected to a relay for executing an associated double command. In the present Examples are changeover switches 10, 11 and 12 as well as relays 13, 14 and 15. Each of the relays 13 to 15 sets the associated contact of changeover switches 10 to 12 when energized and actuates others Switch for executing the command. Is the switching arm 8 z. B. on the forty-seventh Contact and is closed by a ripple control pulse from the switch arriving at the same time, the relay 15 is connected to voltage via the switching arm 8. This impulse means a switching on of the associated consumer, in addition, the switch 12 is actuated. The relay 15 can only be re-energized if a trip command is given in a subsequent transmission program arrives at the point in time in which the switching arm 8 is on the forty-eighth contact. A common switch 16 is connected downstream of the relays 13 and 14. This switch is operated by of the pulse comparator 9 is operated. Is correct the combination of the six impulses of the transmission program not with the mechanically stored one Pulse combination match, then the switch 16 is opened so that the relays 13 and 14 no longer can be excited.

The F i g. 3 shows the fixed part of a SyndJiron voter, i.e. the contact track and furthermore the device for the mechanical storage of the Impulse combination. The part shown is cup-shaped, with the open side in the plane of the drawing and is directed upwards. The opening is limited by a guide ring 17 in which a disc, not shown, rotates. This Sicheibe is driven by the synchronous motor 6 and carries the switching arm 8 and the scanning means for the mechanically stored pulse combinations as well the comparison device for the stored and received pulse combinations. the Disk is inserted into the fixed part in such a way that the switching arm and the scanning and comparing means face the interior of the cup-shaped part. One emanating from the bottom of the pot Sleeve 18 can serve to guide the rotatable disc. The disk carries out every ripple control transmission program exactly one turn. Between the sending predictions it is specified in a Starting position held. Each pulse time in the broadcast program is therefore a very specific position assigned to the disc and therefore also to the switching arm as well as the load and comparison means.

With one contact of the switching arm, the contact path of the synchronous roller is activated during one revolution scanned. The contact track is only provided with contacts at those points where there is also a connection to a relay for command execution. According to FIG. 2, there are thus three contact elements 19. 20 and 21 available, each of which has two contact pieces 22, 23 and 24, 25 and 26, respectively. 27 and which are inserted in the designated places in the Synchion selector pot. The contact elements are inserted from below and held by webs 28. Your connecting lines are connected to the switches 10 to 12, as shown in FIG. 2 shows.

ao To store a combination of impulses, the The base of the synchronous selector pot is provided with radially extending slots. The spacing of the slots among each other corresponds to the path that the disc covers during a pulse time. Every slot is

as expanded in three places. The spacing of the extensions from the center point of the pot are the same for all slots, so that the statements on three Circular paths are arranged. Each slot contains one from the outside at one of the expanded points plug-in pin that protrudes into the inside of the pot. The extensions arranged on the central circular path are marked with a »-» - *, d. H. a pin inserted here means that a pulse must arrive in the associated pulse line.

so that the consistency is maintained. The extensions arranged on the outer circular path are marked with a »-«: with a pin inserted here, if there is a match the impulse combinations in the corresponding im-

; o pulse line no pulse arrives. Finally, the inner circular path is identified by a "0": a Pen in this position is not scanned so it is irrelevant. whether in the assigned pulse time an impulse arrives or not.

According to FIG. 1, the first six pulse times of a program should be decisive for a preselection: therefore only the pins in the slots 29 to 34 that are scanned during this time are of interest. In accordance with FIG. 1 are the pins 35, 37 and 38 on the central and the pins 36, 39 and 40 on the outer circular path. Simi also inserted pins in the other slots, then these must be pushed onto the inner circular path so that they do not affect the scanning.

With the help of the slots 29 to 34 and the pins 35 to 40, the FIG. 1 shown combination of the pulses k _t to k _G are stored mechanically.

The F i g. 4 shows an exemplary embodiment for the mechanical scanning and comparing device. This is located on the rotatable disk 41. The direction of rotation of the disk is indicated by an arrow indicated. While a ripple control program is being received, the disk 41 rotates one revolution. The F i g. 4 also contains a section from the fixed part 42 of the synchronous selector. To simplify matters, only the two outer circular paths on which pins 43, 44

and 45 can be plugged in. The pins protrude on the underside of part 42 in the tap of the scanning device.

On the disc 41, a plate 46 is movably disposed, that of the not shown, upon actuation, excited by the Rundsleucrimpulscn Empfangsrclais sen ¹ · to the plane of the disc 41 is lifted. LHn bent end of a lever 47 is pressed by a spring 48 on the plate 4 <t. The lever 47 is rotatably supported by an axis 49 in two bearing supports 50 and 51. The angled end piece 52 of the lever 47 also carries an axis 53 on which a further lever 54 is rotatably mounted. At one end of this lever 54, a scanning lever 55 is rotatably attached, which rests with a projection 56 on the horizontal part of the end piece 52. A leaf spring 57 tries to push the scanning lever 55 upwards. However, the free end of the lever 54 is pressed by a bracket 58 upwards and thus the scanning lever 55 downwards. The bracket 58 is rotatably supported by an axis 59 in two supports 60 and 61. A spring 62, which is stronger than the leaf spring 57, tries to turn the bracket 58 clockwise. The bracket 58 carries an arm 63 by means of which an electrical switch 64 is opened or closed when the bracket is rotated. In its upper position, the arm 63 hits a cam 65 when the disk 41 is rotated. " fixed part 42 and is thereby pressed downwards.

The end piece 52 carries a parallel offset arm 66 which is fixed against a ring 67 dc: s Part 42 protrudes. At the outer end of the arm 66, a leaf spring 68 is attached, with its bent The end presses against the ring 67. The ring 67 is provided with recesses 69.

The lower ends of the pins 43, 44 and 45 protrude into the path of the scanning lever 55. 4 shown The device is now designed so that if the received limpul combinations match with the stored by the pins 43. 44 and 45 combination of the scanning lever 55 in the Rotation of the disc 41 does not come into contact with any of the pins. In the situation shown was no pulse received: the scanning lever 55 is therefore located below the inner circular path, the is marked by "'". If the combinations match, the outer, with a circular path marked »- <- inserted a pin, as here the pin 44. The scanning lever 55 is then moved past the correctly inserted pin. If they do not match, a pin is inserted on the inner circular path. On this circular path The scanning lever 55 also moves if no ripple control pulse has been received. The scanning lever 55 then abuts against the pin, s; o that the projection 56 is derived from the end piece 52 and the The scanning lever 55 is moved downward by the influence of the spring 62. The bracket 58 is so far rotated so that the switch 64 is opened and the arm 63 is brought into the range of action of the cam 65 will.

The switch 64 corresponds to the switch 16 in FIG. 2. If this switch is open, then a Execution of received ripple control commands prevented. The remains in this notched position Device until the end of the current ripple control program. At the end of the program, the disk 41 has rotated so far that the arm 63 against the cam 65 pushes and is pressed down by this. Thereby, the influence of the spring 62 temporarily switched off, whereby the weaker leaf spring 57 moves the scanning lever 55 so far can move up so that the projection 56 can snap into place over the end piece 52. This will make the one shown Initial state restored.

A received Rundstcuerimpuls causes an ίο lifting of the plate 46. The lever 47 is thereby pivoted about the axis 49 together with the end piece 52, the lever 54, the scanning lever 55, the leaf spring 57, the arm 66 and the leaf spring 68 that the The upper end of the scanning lever 55 is brought under the outer circular path marked with "". The leaf spring 68 comes under the ring 67, so that the scanning device remains in the position described even after the end of the Rundslcucrimpulscs. Only after the pulse interval has been terminated is the leaf spring 68 released through the relevant recess 69, whereby the lever 47 can return to the position shown. The ring 67 and the leaf spring 68 thus effect the mechanical storage of the incoming ripple control pulse until the end of the corresponding pulse interval. The comparison of the combination groups can thus also take place when the round-trip pulse itself has long ended. If an impulse is to arrive, a pin is inserted into the corresponding point on the inner circular path. If they match, the scanning lever 55 is pivoted by the incoming pulse so that it is moved past the inserted pin. If no impulse is expected, a pin is inserted on the outer circular path. If an impulse arrives anyway, the swiveled-out scanning lever hits the pin. The switch 64 is thereby opened in the manner already described for the remaining part of the ripple control program.
The F i g. 5 a and 5 b show a tab 70 which can be used for mechanical storage instead of the insertable pins. The rider 70 is rotatably arranged on an axis 71 connected to the stationary part of the synchronous selector. In the position shown, the two legs 72 and 73 of the rider 70 do not protrude or only slightly beyond the lower edge of the fixed part of the synchronous selector. As a result, the scanning lever cannot come into contact with one of the two legs. This position corresponds to an inserted pin in the circular path "0" in FIG or 75 in the fixed part, as shown in the dash-dotted representation. The respective lower leg of the rider is then almost in a vertical position. It protrudes into the path of the scanning lever on which the disc rotates. With the corresponding position of the riding 70, the left leg 72 protrude, for example, in di <with “t-” and the right leg 73 in the circular path marked with “-”. The tab 70 is made of elastic material, while the stationary part of the synchronous selector can be made of rigid material. So that the tab 70 in the respective! Raststcllung is held, the two legs 72 and 73 each have a locking cam 76 and Π

those in engagement with ribs 78 and 79 on the stationary Part of the synchronous voter. One of the locking cams is used to adjust the rider passed the associated rib. This is possible because the rider is made of elastic material and the legs can thus be deflected laterally.

A plurality of scanning devices offset from one another along a circular path can also be advantageous be used. Various combinations are then stored at the corresponding points on the synchro-dial, which at the same time

10

tig be scanned and from which a combination can be selected.

In the exemplary embodiment described, the means are for mechanical storage of the combination ions with the fixed part and the scanning device with the rotatable part of the synchronous selector connected. Of course, the storage means can also be reversed on the movable one and the scanning device be attached to the fixed part. This has the advantage of a simpler one electrical lead to the switch operated by the scanning and comparing device.
