Abstract

393,206. Valve modulating circuits. TELEFUNKEN GES. FœR DRAHTLOSE TELEGRAPHIE, 12, Hallesches Ufer, Berlin. Dec. 12, 1932, No. 35207. Convention date, Dec. 12, 1931. [Class 40 (v).] A n oscillator o f the Barkhausen-Kurtz type having the grid of the valve 1 at high positive potential and a small bias on the anode is keyed by interrupting the grid voltage at note frequency. A mechanical or vacuum switch type of interrupter may be used or as shown a valve 4 may serve as an interrupter.
