Abstract

716,125. Electromagnetic relays. GENERAL ELECTRIC CO., Ltd. July 2, 1952 [July 6, 1951], No. 16113/51. Addition to 606,502. Class 38(5) In an arrangement for indicating at lamps 31, 32 when an A.C. source 10. 11 is below or above a predetermined voltage, the source 10, 11 feeds a rectifier bridge 12 ... 15 which delivers D.C. to points 16, 17 which supply parallel circuits containing relays 20, 24 respectively; when the voltage is sufficient relay 20 operates closing a circuit to relay 24 which operates contacts 22 serving to reduce the current in relay 20 to just above holding value and contacts 30 serving to energize the lamp 32. Variable resistances 21, 25, 28 are arranged as shown. Alternatively, the resistance 28 instead of being placed in series with the coil 20 may be placed in parallel with it.
