Abstract

261,350. Esau, A. Nov. 10, 1925, [Convention date]. Thermionic generators.-Relates to a shortwave generator in which two valves have their filaments, grids, and plates respectively connected together, common batteries and a common resistance or choke w being provided. The constants of the oscillatory circuit comprise the internal capacity of the valves and the capacities and inductances of the grid and plate leads, but according to the invention a variable additional capacity is provided by the condenser c, whereby the wave-length can be further shortened to an adjustable extent.
