Abstract
388,039. Transmission systems. ESTAUGH, W., 32, Draycot Road, Wanstead, Essex. Aug. 14, 1931, No. 22995. Addition to 233,124 and 269,637, [both in Class 40 (iv), Telephones &c.]. [Class 40 (iv).] The system of the parent Specification is modified by making the voltage of the permanently connected earthed battery j at the transmitting station lower than that of the charging battery f and arranging that telephone or telegraph signals vary the voltage of the inner conductor a between the voltages at the transmitting end due to the charging battery on the inner and outer conductors respectively.
