Abstract

620,312. Thermionic valves. WESTING- HOUSE ELECTRIC INTERNATIONAL CO.. Aug. 14, 1946, No. 24155. Convention date, Aug. 14, 1945. [Class 39 (i)] A grid is composed of inner and outer wire helices 19, 18, the convolutions of which are separated by the supporting stays 17 to which the wires are welded. The convolutions of the two helices are positioned directly in front of each other in a direction at rightangles to the axis of the grid..
