Abstract
560,075. Control systems for space discharge apparatus. BRITISH THOMSONHOUSTON CO., Ltd. Dec. 1, 1942, No. 17068. Convention date, Dec. 10, 1941. [Class 38 (iv)] After several operations of a switch S in the starting circuit of a (fluorescent) discharge device 10, a switch T closes and short-circuits the switch S, preventing further attempts to start the device. The switch T comprises a bimetallic element heated by a resistance 33 in the starting circuit and is therefore maintained closed after operation. Two structural arrangements of the switches S, T and condenser K are described. Specification 542,853 is referred to.
