Abstract
481,054. Electromagnetic r e l a y s. ETABLISSEMENTS EDOUX-SAMAIN SOC. ANON. April 7, 1937, No. 9919. Convention date, April 8, 1936. [Class 38 (v)] In series with the winding of an electromagnetic relay 2 is provided a condenser 1 and a resistance 4 of suitable values, a switch 3 being arranged when closed to short circuit the condenser 1 and relay 2. When switch 3 is opened the condenser charges through the winding of relay 2 which it operates, and thus an impulse or series of impulses may be effected. Resistance 4 may be replaced by the winding of another relay.
