Abstract

147,435. Ges. f³r Drahtlose Telegraphie. Dec. 6, 1917, [Convention date] Void [Published under Sect. 91 of the Act] Electric oscillations, producing. - In a thermionic oscillation-generator tuned circuits are inserted as impedances in the plate circuit for the purpose of minimizing heat-losses, particularly in the electrodes of the valve. The choking circuits for the fundamental and for the various harmonics may be connected simply in series or parallel, or as shown in Figs. 8 or 10. The antenna may be coupled or directly connected in the circuit of fundamental frequency.
