Abstract

378,077. Wired wireless systems. ECKERSLEY, P. P., 82, Swan Court, Chelsea, London. May 6, 1931, No. 13419. [Class 40 (v).] In a wired wireless system employing feeders h, l including a low-frequency transformer p, s a path for high-frequency energy between primary and secondary comprises a pair of condensers c1, c2 with the point between them earthed through an aperiodic circuit comprising a coil k having a high impedance for high-frequency and a low impedance for low-frequency currents. Fuses f1, f2 or other automatic cut-outs are connected in series with the condensers.
