Abstract

129,722. British Thomson - Houston Co., (General Electric Co.). Dec. 8, 1917 Wireless signalling.-The receiving-conductor is formed as a coil 3 lying in the vertical plane containing the receiving-station and the desired transmitting-station 2 and a second coil 9 is placed transversely across the coil 3, approximately at right-angles thereto, with the object of screening the receiving coil from the undesired waves emitted from an adjacent transmitting-station 1. The receiving-circuit 3 is tuned to the frequency of the station 2 by a capacity 8, and the desired signals are detected by a vacuum-tube 4 or other suitable detector. The screening-coil 9 is tuned by a capacity 11 and inductance 10 to the frequency of the interfering station 1.
