Abstract

629,628. Velocity-modulated tubes. WESTINGHOUSE ELECTRIC INTERNATIONAL CO. Feb. 20, 1947, No. 5005. Convention date, July 11, 1940. [Class 39 (i)] [Also in Group XL (b)] A thermal tuning member, such as plate 33 supported by bimetal 60, has portions extending into each of two resonators. When the bimetal is heated, as by electrical element 64, or by immersing the whole device in a temperature-controlled bath, the plate moves further into one resonator and out of the other, thus enabling the tuning of the two resonators to be equalized. The plate 33 moves in a slot in the dividing wall 29, which also carries the drift tube 27 and the feedback loop 57. The collector electrode 47 is insulated so that it acquires a negative charge and deflects the spent electrons to the wall of container 1. Cooling may be obtained by coil 3. The Specification as open to inspection under Sect. 91 comprises also replacing the bimetal by a single expansible element, or tuning the resonators without the use of plate 33 merely by immersing them in a bath, the temperature of which can be controlled from that of liquid air upwards. This subject-matter does not appear in the Specification as accepted.
