Abstract

310,043. Telefunken Ges. fiir Drahtlose Telegraphie. April 21, 1928, [Convention date]. Vacuum tubes.-A thermionic valve generator for very high frequencies has all the circuit elements including the oscillating circuits enclosed in the envelope, and the frequency is varied inductively or capacitatively from outside the envelope. As shown, a push-pull generator has two triodes R, R1, inductances L, L1, and a condenser consisting of two plates D, D1 welded to the anodes. The frequency is varied by means of an external cylinder, not shown, in capacitative relation with the plates D, D1 or by means of a short-circuited ring coupled with the inductances. Specification 297,775 is referred to.
