Abstract
399,074. Valve modulating circuits. TELEFUNKEN GES. FœR DRAHTLOSE TELEGRAPHIE, 12, Hallesches Ufer, Berlin. Feb. 1, 1933, No. 3135. Convention date, Feb. 1, 1932. [Class 40 (v).] An ultra-short-wave oscillator is modulated by applying the signal voltage to an inner grid Gm. The oscillator is of the type employing a positivelycharged grid G and an anode A with small negative voltage, the frequency being dependent on the time of electron oscillation within the valve. A further shielding grid Gs, held at a fixed positive voltage, may be interposed between the grids G, Gm.
