Abstract
602,775. Electron discharge apparatus. WESTERN ELECTRIC CO., Inc. Nov. 14, 1945, No. 30431. Convention date, July 6, 1944. [Class 39 (i)] Electron discharge apparatus comprises a cathode, a target and a pair of concentric spherical electrodes. In Fig. 1, an amplifier comprises a cathode 17 and a target 24, two spherical electrodes 16 and 13, the latter formed as a coating of colloidal graphite known under the Registered Trade Mark " Aquadag," on the surface of the envelope 10. The electrons, concentrated in a beam by the apertured cylindrical electrode 22 and annular plates 23 are directed by the spherical electrodes towards the target in curved paths which lie on the surface of a sphere concentric with the electrodes. The current to the anode 24 can be varied in accordance with an input signal applied to the inner spherical electrode. In the oscillation generator shown in Fig. 2, the inner sphere 116 forms a cavity resonator with two gaps, one opposite the anode 124 and the other opposite the cathode 17 which is surrounded by grid 34. The outer electrode 113 is held by a rigid lead-in conductor 33 sealed in the stem of the enclosure 10 of vitreous material. Energy is abstracted from the cavity resonator by means of a probe.
