Abstract

820,301. Thermionic valves. M-O VALVE CO. Ltd. Jan. 16, 1957 [Jan. 16, 1956 ; Oct. 15, 1956], Nos. 1483/56 and 31387/56. Class 39(1). [Also in Group XL(b)] A thermionic valve, e.g. a klystron or magnetron, has a window for the transmission of oscillations consisting of a plate of synthetic corundum of single crystal form which is so orientated that its optic axis is perpendicular to the direction of the electric vector of the oscillations. The optic axis may be in the plane of the window or perpendicular to it. The window may be sealed in a metal cup as described in Specification 796,884. Specification 820,302 also is referred to.
