• switch on a delay relay with the rotary selector so that when short interference pulses, synchronous motor and synchronous selector do not work Tension to be put.

The invention is based on the object of a ripple control receiver of the type described at the outset in such a way that a continuously running motor can also be used to, if necessary To avoid starting errors of the synchronous motor. This object is achieved according to the invention in that between Synchronwäh- · ler and synchronous motor designed as a pulse length switch ι coupling device is provided, which can be controlled by a TF receiving relay. Preferably the coupling device mechanically locked after a start impulse of normal duration.

On the basis of the drawing, in which two exemplary embodiments of the rotary receiver according to the invention are shown schematically, the invention is explained in more detail.

The coupling axis 4 is actuated via a coupling lever 16 which can be actuated by a coupling device 17. The clutch magnet 17 is connected to voltage via a TF contact 18 of the TP receiving relay, not shown in the drawing, when a pulse arrives. Another contact spring set 20 is actuated by the armature 19 of the clutch magnet 17, which applies voltage to the synchronous motor 1. The power supply terminals are marked with 21 * A brake spring 22 is used to switch off the gearbox in the reduction gear 2. ^!

The operation of the round trip receiver according to FIG. 1 is like follows'.

If contact 1S is closed when the rounding control signal arrives, the clutch magnet 17 receives voltage and pulls its armature 19, whereby the coupling axis 4 is pivoted once via the coupling lever 16 and the wheels 5 and 6 are in engagement and on the other hand the synchronous motor 1 is connected to voltage via contact 20 »The latter drives via the reduction *;

i drives 2 the coupling wheel 5-on. As a result, the control disk 12 is moved in the direction of the arrow. If a pulse of sufficient length occurs, the coupling axle 4 moves out of the area of the recess 13, so that when the control pulse ceases, the two wheels 4 and 5 are mechanically locked by the cam disk 12 for one revolution. In a corresponding way, the armature 19 of the clutch magnet also remains in the attracted position, so that motor 1 remains switched on continuously via contact 20. At the same time as the control disk 12, the lock disks H and 9 are also driven , ;; ie after having covered a certain predetermined path, actuate the contact sets 10 and 11. In the row with the external contacts - the contact spring set 11 is the -, vices. of a polarized trigger 35 is switched. the central contact falls into the notch 9 'or the central contact is lifted; ·; üuroh liocke 9 '' a control command via contact 1-3, either the right or the left winding of the trigger receives voltage, "so that it carries out a corresponding switching action." coupling axis 4 with di-r V / MPACT of the return spring of the Kupplungsraagneten 17 in i-: ie Aussparunf 'back and disengages the wheels 5 and 6. the spring 14, the control disc 12 in the correct Auagangslage is zurück'gcführt _t obtained by the in Fig. 1 position shown is marked. With the help of the cam disk 0, further switching operations can be triggered in the same way.

In the case of shorter pulses, the coupling axis 4 falls back into the recess 13 after the pulse has ceased, without a switching process having been triggered. The recess 13 is dimensioned so that it requires a certain minimum pulse length to the

The ripple control receiver according to FIG. 1 can also be operated in such a way that the motor 1 remains switched on continuously. There is no need ^: then the contact spring set 20. This has the advantage that the start-up scattering of the motor .1 is completely eliminated ·!

Fig. 2 shows an embodiment, the same parts being given the same reference numerals. The coupling axis 4 is now driven by the synchronous motor Ί via worm 23 and worm wheel 24. One bearing point 25 is feat, while the other bearing point is in a clutch lever 26. The clutch lever 26 is pivotable about an axis 27 from the clutch magnet 17. The extended armature 19, which is under the action of a resetting, spring force, is guided in two pins 2S de3 clutch lever. The clutch lever 26 also actuates a contact spring set 34 that puts voltage on the motor 1 with the aid of a pin 23 , which corresponds to the contact spring set 20 according to FIG. 1

The front end of the clutch lever 26 carries a sliding block 30, which with. a control cam 31 of the clutch wheel 6 can interact. In the control curve of the disk 6 there is a recess 32 which corresponds to the recess 13 according to FIG. T corresponds to. In Fig.; J this part of the clutch disc 6 is shown on an enlarged scale. In the starting position, the sliding block 30 lies on the lower edge 33 of the recess 32 under the action of the spring 14

If the clutch 3raagnet 17 receives when a start position occurs: naIs voltage, its armature 19 attracts and pivots the clutch lever 26 in the direction of the arrow. In this case, voltage is applied to the motor via the contact spring set 34, which now drives the coupling pin 2 with pinion 5. At the same time the KuppLun .- ^ wheels -3 and 6 are brought into engagement with each other, whereby the wheel 6 is driven clockwise overcoming the force of the pedal 14! will.
