Abstract
556,511. Valve relay circuits. BRITISH THOMSON-HOUSTON CO., Ltd. July 22, 1942, No. 10254. Convention date, July 23, 1941. [Class 40 (v)] A time delay between the closing of a switch 12 and the operation of a relay 8 in the anode circuit of a grid controlled discharge device is obtained by a resistance condenser combination 17, 18 connected between the grid and a potential divider connected across the alternating current supply source. When the switch is open the condenser is charged from the supply through the rectifier 21 in parallel with the grid cathode path of the discharge tube and through resistance 19. Specification 496,641 is referred to.
