Abstract
564,764. Control systems for consumption apparatus. IGRANIC ELECTRIC CO., Ltd. March 10, 1943, No. 3892. Convention date, March 11, 1942. [Class 38 (iv)]. Inductive control.- The range of control obtained from a saturable reactor in series with a translating device, such as a group of lamps 1, is increased by means of a condenser in circuit with its alternating current winding 2e forming an oscillatory circuit adapted for resonance. The arrangement shown comprises a condenser 5 in parallel with the winding and a condenser 6 in series with both.
