Abstract: 542,970. Electron oscillators; resonators. MARCONI'S WIRELESS TELEGRAPH CO., Ltd. July 29, 1940, No. 12309. Convention date, July 28, 1939. [Classes 39 (i) and 40 (v)] An oscillator consists of a concentric line resonator 2, 3 through which an electron beam passes and is velocity modulated at the gap 4 ; a horn 31 radiates from the gap formed between the end 21 of the tube 2 and the outer line 3. An iris diaphragm may be used to limit the radiation. The tube 2 is of a length corresponding to a ¢ wave or multiples thereof. An arrangement is described of a resonator with closed ends and two gaps of unequal length.
