Abstract

521,424. Thermionic valves and valve circuits. TELEFUNKEN GES. FUR DRAHTLOSE TELEGRAPHIE. Nov. 18, 1938, No. 33653. Convention date, Nov. 18, 1937. [Classes 39 (i) and 40 (v)] In a receiver, amplifier or oscillation generator using a valve with a perforated anode 4 surrounded by a screen 5 at a lower bias than the anode to prevent electron bombardment of the envelope, the screen is capacity coupled to the anode so that they carry substantially the same A.C. potential. As shown the screen is connected to the cathode through an inductance D and through a condenser C to the anode via the lead to the output transformer La. The anode may consist of radial plates and the coupling between anode and screen effected by concentric leads, that from the anode being tubular.
