Abstract

193,387. Ges. f³r Drahtlose Telegraphie. Feb. 14, 1922, [Convention date]. Thermionic generators; keying and modulating systems and apparatus.-A negative potential is applied to the grid of a thermionic generator by means of a resistance R, shunted by a condenser C, and inserted in the plate circuit between the cathode F and the negative pole of the high-tension supply S. The value of the resistance R may be varied by keying, or through a microphone.
