Abstract

147,447. Ges. f³r Drahtlose Telegraphie. May 28, 1919, [Convention date]. Electric oscillations in line wires, signalling by.-Installations in which high-frequency signalling currents are superimposed on power distribution lines, indicated at 1, are provided with insulated aerial conductors 3 adjacent to gaps 2 in the distribution line, in order to form a bridge for the high frequency currents. The aerial contains a condenser 5 and coil 4 and is preferably tuned to the signalling frequency. The aerial may be earthed through a condenser of large capacity.
