Abstract

591,356. High - frequency discharge apparatus and circuits therefor. WESTERN ELECTRIC CO., Inc. July 19, 1944, No. 13866. Convention date,- May 7, 1943. [Classes 39 (i) and 40 (v)] In a high-frequency electrical device, such as the multigap velocity-modulated oscillator shown, a lead 19 which is immersed in the electromagnetic field is adjusted in length so as to minimize the voltage induced therein and a damping resistance 29 is inserted in the lead circuit outside the field boundary. Energy losses in the lead are thus reduced and parasitic oscillations discouraged. The length of the lead may be reduced by building up a rounded projection 24 on the inside the resonator 16 ; in certain cases it may be necessary to lengthen the lead, 'when the projection is placed on the outside of the wall. By-passing of the high-frequency currents at the boundary is secured by the capacity formed between the lead and the projection, with the dielectric plug 25 filling the space between them. If there are two leads the damping-resistors 29, 30 and chokes 27; 28 are arranged symmetrically, the centre point being connected to the resonator directly, as shown, or through a capacity.
