Abstract

955, 586. Controls for relays. E. LEROY. May 31, 1962 [June 6, 1961 ], No. 21044/62. Heading G4H. A D.C. relay 1 having a current source 8 situated adjacent the relay is operated by a remote bipolar switch 5 between the output terminals of which there is a rectifier for converting an A.C. current produced by the source to a D.C. current. The relay thus cannot operate unless the rectifier is included in the circuit, i.e. unless the switch is closed. A smoothing condenser 6 is connected across the terminals of the relay. In a modification (Fig. 3 not shown) the secondary winding 3 of the transformer forming part of the source is connected in series with the condenser 6 between one of its plates and the line B and the primary winding is fed by a battery driven oscillator. In a further modification of the apparatus shown the source 8 is replaced by a battery driven oscillator.
