The marked synchronous operation is practically inevitable. 65 tion "+" means "impulse", the designation These deviations result, for example, from "-" means "no impulse". The six combinations of a shifted start position of the switching arm or position impulses enable a selection from 64 com-play in the reduction gear between motor and combination groups.

On the basis of FIG. 2 describes how a ripple control receiver works with preselection. Via the lines 1 and 2 connected to the electrical supply network, the ripple control pulses reach an input filter 3. A relay 4 connected to this is excited by the received ripple control pulses and closes a switch 5. As a result, a synchronous motor 6 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 transmission 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. For example, if the switch arm8 is 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 the pulse comparison device 9 operated. Is the combination of the first six impulses of the broadcast program correct? does not match the mechanically stored pulse combination, then the switch 16 opened so that the relays 13 and 14 can no longer be energized.

The F i g. 3 shows the fixed part of a synchromesh dial, 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 disc is driven by the synchronous motor 6 and carries the Schaltann 8 and the scanning means for the mechanically stored pulse combinations as well the comparison device for the stored and received pulse combinations. the Disc is inserted into the fixed part in such a way that that the switching arm and the scanning and comparison means facing the interior of the cup-shaped part are. A sleeve 18 extending from the bottom of the pot can be used to guide the rotatable disk to serve. The disc executes exactly one revolution with each ripple control transmission program. Between the broadcast programs it is held in a fixed starting position. Every time in the broadcast program is therefore a very specific position of the disc and therefore also of the switching arm and the Assigned scanning and comparison means.

With a contact of the shift arm, the contact path of the synchronous dial is 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 are therefore three contact elements 19, 20 and 21 available, each of which has two contact pieces 22, 23 or 24, 25 or 26, 27 and which are plugged into the synchromesh dial pot at the designated places. 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.

To store a combination of pulses, the base of the synchronous selector pot is radially extending Provided with slots. The distance between the slots corresponds to the path taken by the disk travels during a pulse time. Each slot is expanded in three places. The spacing of the extensions from the center of the pot are the same for all slots, so that the extensions to three Circular paths are arranged. Spring slot contains one from the outside at one of the enlarged places plug-in pin that protrudes into the inside of the pot. The extensions arranged on the central circular path are marked with a "+", i. H. a pin inserted here means that in the associated pulse time a pulse must arrive so that the correspondence is maintained. The on Extensions arranged on the outer circular path are marked with a "-"; at one here The inserted pin may match the pulse combinations in the corresponding pulse time no impulse arrives. Finally, the inner circular path is identified by a "0"; a Pen in this position is not scanned, so that it is irrelevant whether in the assigned pulse line an impulse arrives or not.

According to FIG. 1, the first six pulse timers of a program should be decisive for a preselection, so only the pins in slots 29 to 34 that are scanned during this time are of interest. Ir agreement 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. If pins are also inserted 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 1 shown combination of the pulses k _t to k ₆ are stored mechanically.

While receiving a ripple control program, the disc 41 performs a rotation. 4 also contains a section from the fixed part 42 of the synchronous selector.
