Abstract

604,939. Frequency measurements. PHILCO CORPORATION. Aug. 30, 1945, No. 22350. Convention date, Aug. 30, 1944. Drawings to Specification. [Class 37] [Also in Group XL (c)] The recurrence frequency of a sawtooth generator is indicated by a D.C meter connected in the anode lead of a constant current valve discharging a capacitor slowly. In the circuit described, the capacitor is charged rapidly through a thyratron upon the reception of a triggering signal.
