Abstract

590,777. Discharge apparatus. STANDARD TELEPHONES & CABLES, Ltd. May 5, 1944, No. 8594. Convention date, Jan. 22, 1942. [Class 39 (i)] An electron discharge device comprises a grid, 58 concentrically surrounding a cathode 50, and an anode 52 surrounding the grid, a cavity resonant circuit 53 connected between the anode and grid being arranged symmetrically longitudinally and coaxially with respect to the electrodes and an adjustable coaxial line 59 being connected between the grid and cathode for tuning. Capacity coupling between the grid and resonator 53 is provided by a member 56 secured to the resonator and projecting into the grid. The anode 52 may be cooled by providing fins thereon and allowing cooling air to flow through openings 67 into the resonator which is outside the vacuum enclosure.
