Description

GERMAN

The present invention is concerned with a circuit arrangement for movable spin marks for voters with one direction of movement and without a fixed rest position.

With such, voters, to prevent continuous rotation in the event of faults in multiple or in the test paths or with free choice, if no free exit was found, a shutdown of the voter after a certain. Time made. With such a well-known. Arrangement for this is Thermo * - contacts provided). However, these have a long cooling time, so> that in the case of quickly successive assignments already before the test or overflow all outputs a shutdown of the selector can take place. If one does not want to accept this disadvantage., so one must either track the passage of time to return allow the thermal contact to return to its original position, or you can use a Circuit arrangement in which an occupancy is immediate, even if the thermal contact is not yet in the output division has returned, can be done by spending an additional relay that the The thermal contact does not switch on again until it has returned to the starting position. With the latter The arrangement must therefore · in the case of spinning, accept a longer spinning time in addition to the additional expense will. The same disadvantages also have mercury time switches.

Furthermore, such circuit arrangements are known in which. Time constant circles, if applicable optionally adjustable, provided as a timer. The execution of the switching order is carried out by displayed at a predetermined voltage or at a predetermined current. In a known arrangement In this way, the running time of a free voter, namely a call distributor, is determined, by placing a pending call in a call finder multiple after two rounds of a call finder is passed on to a second corresponding voter. The time after which the distributor advances is through a. Capacitor and resistor in parallel circuit to one Relay determined.

In another, such. Arrangement is the time constant circle on the grid of a gas-filled Tube switched so that an ignition of the same takes place after a predetermined time. Through the The associated anode current is controlled by a relay that carries out the switching order.

A disadvantage of the arrangements on time constants. The basis is that, with voters who have exactly defined: movable starting position required ". is, cannot be used. Also, are such Circuit arrangement

Arrangements sensitive to fluctuations in operating voltage.

According to the invention, the disadvantages of the known. Arrangements avoided, that at the respective voter is provided with a counting element with which the number of steps or decade required is to go from the current starting position from a certain position, preferably again the Starting position to be reached is counted, this predetermined position leading or lagging can be marked, and that the counting member is still 'for other purposes, for example for individual, Activation, for the evaluation of the rearward signaling, for the evaluation of special characteristics, or to convert license plates

An arrangement based on the capacitor scoop principle with sinetm Selector contact which is actuated at every step or every decade can be provided. With overflow A suction capacitor is then connected in parallel over each step or each decade, the after each parallel connection receives its output potential again, to a storage capacitor, and with the help of the voter contact. The achievement the specific: position of the selector is at a predetermined) voltage on the storage capacitor, after a predetermined; Number of parallel connections is present, preferably by means of voltage-dependent Members evaluated, displayed.

An arrangement can also be used as a counting device be provided with a counting throttle.

Two discs can also be used for counting of which: one is firmly connected to the axis of choice; is while the other is fixed is arranged. These work together in such a way that at the beginning of the voting run by a magnet both fixed and movable

Part is made a mark, so> that so · - _r soon the mobile disk attached to. the stationary ■ pane assumes the marked position, the completion of the switching job is displayed.

The invention and further developments thereof are set out below. Hand of the drawing explained in more detail. In this only the circuits that are absolutely necessary for understanding the invention are shown. In the exemplary embodiment, a call searcher with a motor selection drive is provided. With the selector contact <i £, which is actuated by a cam disk, which is arranged on the selector axis, the decades are counted. An arrangement based on the capacitor scoop principle is used as the counting device. When the selector is in the rest position, the storage capacitor C1 is discharged via the 10 r contact. The voter is started with the relayJ ?. The storage capacitor C1 always has a certain output potential. During the voting period, the decade-in contact dk is switched over briefly every decade. As a result, the scoop capacitor C 2 is connected in parallel with the storage capacitor Cl. The pumping capacitor C2 receives a certain output voltage again and again after each parallel connection via the quiescent side of the decade contact dk. If the selector overflows over all decades, the contact has been actuated dk η times. On the n + Ith actuation of the same, the storage capacitor C1 then reaches such a potential that the glow lamp GH ignites. The relay UI in the glow lamp circuit responds. With the 5 w-contact, both windings of the motor are energized, thus stopping the selector. The [/ relay is held by its U II winding via the 11 «contact. The ignition of the glow lamp shows a spinning event on, which is signaled via the contacts 7 p, Sr, 9m. With 4 ω the starting chain is switched on to the next voter. i? -Rela, is falling off. With 6r the motor windings are switched off and with 1Or the storage capacitor is brought back to the output potential. This fault signaling device only comes into effect in the event of a fault. In the event of a fault-free setting, the P relay in the test circuit is activated and the selector comes to a standstill.

- In addition to the counter arrangement used in the exemplary embodiment, selector relays, Counting drcsseln, counting relays, multi-cathode glow lamps or counting arrangements that are made with the selector are coupled, used ,. The latter can. so> be designed that two disks; are provided, one of which is fixed to the voter axis is connected, while the other is fixedly arranged. At the beginning of the electoral run with the help of a magnet on both the disc, which is firmly connected to the dial, and on the fixed. Disc made a mark. In the case of spinning, when reaching, the same Position through the disc connected to the voter axis on the fixed disc over the marking a. Circuit formed. A relay is brought into this and. the voter shut down.

When using multi-cathode glow lamps as counting element, at every decade or every step an induction shock is given to the relay tekatho de same. With a relay in the one. Cathode circuit, which corresponds to the spinning case, a spinning mark is then made .. At normal testing process, the electron beam is through, a. Reset pulse back to the starting position brought.

If counter throttles are provided, then each Step or every decade for a certain time the circuit is closed via the choke. Until saturation the same flows a certain step current. In this case, the relay in the circuit has FeW electricity. After the specified number of. Steps, for example after all outputs have overflowed, increases the current suddenly starts, the saturation is reached, a relay in the circuit of the counter throttle can respond. The voter is made with the help of a contact this relay is shut down. The step to be counted or Decade number can be in the form of a corresponding Voltage or number of turns of the counting choke can be set. The starting position of the counting throttle is restored by reversing the current.

Such counting elements are particularly economical if they are also used for other purposes in the respective circuits, for example for individual activation devices, zti3s !! ii | je | llits- ^; Valuation of the backward signing gaba, in particular? if the type of reverse indicator by a certain number of, impulses is determined, particularly for evaluating characteristics such as ^beispiels-: as intrusion, different to convert dialed digits or .Umwandlung of Gleichstrotnittipulsen .in induction shocks or, alternating currents frequency.
