Abstract
253,079. Wired Radio, Inc., (Assignees of Duncan, R. D.). June 5, 1925, [Convention date]. Drawings to Specification. Induction, preventing.-In a wired wireless sys. tem, three-phase carrier currents are superimposed on three-phase power lines so as to secure a uniform distribution of carrier current and to prevent interference with receivers external to the system. The lines are connected to the receiving set in such a way that the effect of one branch of the carrier input is reversed in phase to give an increased resultant current vector. Specification 245,725, [Class 40 (v), Wireless signalling &c.] is referred to.
