Abstract
408,323. Wireless transmitting systems. LORENZ AKT.-GES., C., 1, Lorenzweg, Tempelhof, Berlin. Oct. 7, 1932, No. 27943. Convention date, May 31. [Class 40 (v).] A coil arrangement L, Fig. 1, is provided in the parallel conductors E forming a power line feeding a transmitting antenna A for neutralizing or preventing the flow of co-phasal currents of the transmitting frequency. It may comprise two intercoupled coils wound in the same direction, one of which is included in each conductor ; similar coil arrangements may be arranged at intervals along the line. An auxiliary line may feed counter-phasal power from the transmitter S into the coil arrangement to neutralize co-phasal currents flowing therein, or said counter-phasal power may be derived from the line E, Fig. 3, being fed through a coupling device K to a phase-changing device V and thence to a coupling arrangement G in the line E.
