Abstract

230,853. Telefunken Ges. f³r Drahtlose Telegraphie. March 15, 1924, [Convention date]. Thermionic generators.-In an independently excited valve transmitter, the grid current of the amplifying valve or valves g is derived from the terminals of a condenser c in the oscillatory circuit of the control transmitter, which circuit is in parallel with the grid and cathode of the oscillation valve a. Blocking condensers e, f may be provided', and inductive capacities h, h' and variable ohmic resistances i, i<1> are preferably arranged in parallel with the oscillation valve a or the amplifying valve g or both. Specification 179,006 is referred to.
