Abstract
432,726. Converting. RANGABE, A. R., and EINTRACHT, S. J., 5, Theobald's Road, London. Feb. 2, 1934, No. 3519. [Class 38 (ii)] An arrangement for supplying high voltage A.C. to luminous discharge tubes 14 from a low voltage D.C. source comprises a motor driven rotary reversing switch 6, a step-up transformer 12, and a condenser 15 serially connected on the secondary side of the transformer and of such magnitude in relation to the other circuit constants and the speed of the switch that break occurs only when the current has fallen to zero. Figs. 1 and 2 show alternative arrangements of rotary switch connections. The motor may serve also as the driving element for the tube when the latter forms a moving sign, and provision may be made for cutting out the reversing switch where A.C. is available.
