Abstract
601,924. Protective cut-out systems. OPERADIO MANUFACTURING CO. Nov. 6, 1945, No. 29490. Convention date, Feb. 19. [Class 38 (v)] The electrodes 15, 16 of a high-frequency, dielectric heating system are energized from a high frequency generator 10 through an oscillatory circuit 13, 14, the generator being supplied from a source 20 over contacts 23, 24. On the occurrence of an are between the electrodes, a circuit is completed from an auxiliary source 50 of D.C. or low frequency, to a coil 26 which pulls up its armature 27 to separate contacts 23, 24. Simultaneously, contacts 40, 42, in a maintaining circuit are closed, so that to release the armature, a contact 36 has to be manually opened. Radio frequency blocking . chokes 31, 33, and a low frequency blocking condenser 19 are also provided.
