Abstract
592,664. Valve generating circuits. BURTON, H., PARISH, P. G., and ROTOL, Ltd. Sept. 26, 1944, No. 18389. [Class 40 (v)] Push-pull high-frequency oscillator has anode and grid circuits tuned by simple Lecher wire systems and anodes connected through a condenser 8, the plates of which may be used for dielectric heating. Switching and relays incorporate time delay for enabling filaments to heat, safety measures operated by excess current, controlled process-timer and visual indicators.
