Definitions

  • the invention relates to a receiving device for a remote control system connected to an alternating current network and designed to control or effect deiinite operations, and more particu- 5 larly to such receiving devices controlled by a distant, impulse-sending transmitter, and wherein the selection or control of the different operations is determined by the length of time between a plurality of successive impulses.
  • the principal object of the invention is to provide a receiving device, connected to an alternating current network, which is started into operation by a starting impulse; this is followed by a preparing impulse, which prepares, or sets a l relay, which relay in turn is actuated by an operating impulse which follows the preparing impulse by a predetermined time interval.
  • the time intervals between the several impulses determine which of the plurality oi receiving devices con- 20 nected to a common network will be operated by the impulses.
  • FIG 1 shows an arrangement wherein tilting relays are employed
  • 30 liigure 2 is an arrangement in which holding relays are employed
  • Figure 4 is a diagrammatic view showing an 35 amplification of the mechanism and wiring cooperating with the synchronous motor.
  • Receiving devices embodying the invention are applicable to the remote control of various mechanisms and operations, e. g., switching on and off 0 ci lighting networks, synchronization of clocks,
  • the present invention is an improvement in distant control installations employing contact selectors at a transmitting and at a receiving station, which are run synchronously and in the same phase, in which system from time to time an impulse is sent out when the contact arm of the receiving selector contacts with one of the selector contacts connected to a 50 controlling relay.
  • This invention relates to a receiving arrangement for remote control installations according to the combination method operating through contact selectors driven by synchronous motors,
  • At least one primary relay which upon receipt of a preparing impulse, prepares a secondary or final relay for operation by an actuating impulse occurring at a predetermined time interval following the preparing impulse, whereby the secondary 5 relay is actuated for effecting the desired operation.
  • the primary relay is in series with the secondary relay, is connected to a selecto; ⁇ contact and is connected to the ofi-normal contacter of the contact selector.
  • 'I'he primary relay can be 10 in the form of a tilting or multiple winding relay or of a holding relay.
  • the two windings can be connected on one side with one network conductor and on the other side to a selector contact, or through the off normal contactor to the other network conductor.
  • the primary relay is a holding relay
  • the winding can be connected either on one sideto one network conductor and on the other side to the selector contact, and also through the holding contactar and the off normal contactor to the other network conductor, or on one side to the selector contact and also through theholding contactor to one network conductor, and on the other side through the off normal contacter likewise to one network conductor and also through a resistance to the other network conductor.
  • the selector contacts which are located between the selector contacts for the primary and secondary relays are connected to the oinormal contactor, so that the primary relay is thrown to its original position and therefore will not prepare the secondary relay for operation by the next impulse on the network.
  • the receiving means of the present invention has the advantage that with a great capability of selection the cost of required relays and contactors is very small.
  • the employment of tilting relays has the further advantage that since the magnet system is only energized for a short time it can be considerably overloaded, whereby extremely small, simple and consequently inexpensive constructional forms can be employed.
  • the contact or wiper arm 2 is connected to one network conductor A through tact I0 is connected to one winding II of a primary relay I2 formed as a tilting relay.
  • the selector contacts I3, I4 are connected to the windings I5 and I 6, respectively, of a secondary or nnal relay I1, likewise in the form of a tilting relay; and the selector contacts I8 located between the selector contacts I Il and I3, are con ⁇ nected to the network conductor A through an oiI-normal contactor I9, which in the initial position of the contact arm 2 is likewise separated from the contactor 1.
  • Motor 9 is connected, through suitable reduction gearing, to drive a shaft 9a, on which shaft'is mounted a cam 9b and the wiper or contact arm 2. ⁇
  • the cam is provided withsa short, low portion Ri,
  • the working contactor 3 On the receipt of an impulse in the receiving relay 4, the working contactor 3 is momentarily closed.
  • the synchronous motor 9 is thereby energized through the circuit A, 3, 2, 5, 8, B, and will then set the contact arm 2 of the contact selector I in rotation.
  • the contactors 6, 1 Shortly after the starting of the synchronous motor 9 the contactors 6, 1 are closed, by the action of portion R2 of cam 9b, to close a circuit through the winding 8 of motor 9 to maintain it in operation.
  • the break between the contact ann 2 and the selector contact 5, which took place shortly after the starting of the synchronous motor 9, has consequently no effect on the operation of the synchronous motor 9.'
  • the receiving relay 4 is obviously also deenergized, so that its working contactor 3 will again drop.
  • the winding II of the primary relay I2 is energized through the circuit A, 3, 2, I0, II, B.
  • the working contactor 2l is then thrown over, and thereby the secondary or final relay I1 is connected to the network conductor B and so is prepared for actuation by the next impulse.
  • the winding I5 ofthe secondary relay I1 is energized through the circuit A, 3, 2, I3, I5, 2I, 22', 22a, B, and the working contactor 22 is thrown over, and the connection made by mechanism shown diagrammatically at 22a for effecting the desired operation in the appropriate manner.
  • the apparatus In case the receiving relay 4 remains energized, as by a continued current, when it should be deenergized, (a condition which might result from some interference with the transmission of the impulses), the apparatus would not function as it should, because no current should be on arm 2 when it engages contacts I8. If current is on arm 2 at this time, a circuit is closed through 3, 2, I8, 20, B, to energize coil 20 and return 1t to its original or unprepared position.
  • the modified receiving mechanism disclosed in Figure 2 differs from the arrangement of Figure 1 only in that for the primary relay a holding relay I2' is employed instead of a tilting relay. 'I'he Winding 24 of this holding relay I2' is connected on one side to the selector contact I0 and the holding contactor 25 connected to the network conductor A, and on the other side through the off-normal contactor I9 to the network conductor A and through a resistance 25 to the network conductor B.
  • Fig. 2 can also be made so that the o-normal contactor I9 is connected in series with the holding contactor 25.
  • the oil?- normal contactor I9 which is then normally closed is here momentarily opened shortly before reaching the initial position of the contact arm 2, whereby the holding current circuit for the primary relay I24 is opened and' thereby deenergized.
  • FIG. 3 there is shown a constructional form with three primary relays made as tilting relays.
  • Each of these primary relays E21, I22, I23 again com-prises two windings I I, 20, which are all connected on one side to the network conductor B and on the other side one Winding of each relay is connected to the off-normal contacter I9, and the other Winding to a selector contact 28, 29, 3U respectively.
  • the contactors 2i of the primary relays i21, i221, i23 are arranged in series with one another, namely, between the secondary relay il and the network conductor B.
  • the unused selector contacts I 8 arranged between the selector contacts 28 and I3 are here also connected to the oit-normal contacter I9.
  • a selective system responsive to a plurality oi impulses spaced from each other by given time intervals comprising a rotary contact arm, a plurality of spaced contacts with which the contact arm makes successive contactfa normally inoperative constant speed motor for driving the arm, means including a selected iirst one of said contacts normally engaged by the arm for closing a circuit to the motor upon the receipt oi the iirst impulse, means for closing an independent circuit for the motor, including a switch closed whenever said rotary arm is not in position to engage said contact, a primary relay, circuit connections including said contact arm and a second selected one of said contacts for actuating said primary relay upon the receipt of a second impulse in proper time relation to said rst impulse, said relay having means whereby it is maintained in operated position after the impulse ceases, a secondary relay, means whereby said primary relay prepares a circuit for the secondary relay when it is operated, means including a third selected contact and said rotary contact member for completing the circuit to said secondary relay upon receipt of a third impulse in
