Abstract

423,990. Valve generating circuits. NAAMLOOZE VENNOOTSCHAP PHILIPS' GLOEILAMPENFABRIEKEN, Emmasingel, Eindhoven, Holland. July 30, 1934, No. 22191. Convention date, Sept. 6, 1933. [Classes 39 (i) and 40 (v)] A magnetically-controlled oscillator of the split-anode type has two or more pairs of anodes 2, 4 ; 3, 5, symmetrically arranged round a cathode 6, and opposite anodes of each pair are connected together and to the respective sides of the tuned output circuit 8, 10. The circuit oscillates by virtue of negative resistance, and the present system enables oscillations to be produced at higher frequency than with the normal split-anode magnetron.
