Abstract

716,684. Thermionic valves. STANDARD TELEPHONES & CABLES, Ltd. Aug. 1, 1952 [Sept. 26, 1951], No. 19519/52. Drawings to Specification. Class 39(1) In an electron tube in which one or more grids have cooling vanes extending beyond the electrode system, the anode surface also extends beyond the electrode system, so that the distance between the anode extensions and the cathode axis is nowhere greater than the corresponding distance for the original anode surface. The anode continutions have apertures opposite the grid vanes so that heat therefrom may pass through. Apertures are also provided in the suppressor grid, if this comprises a metal frame. Screening gauze may be provided between the anode and the control grid vanes.
