Abstract

220,452. Western Electric Co., Ltd., (Western Electric Co., Inc.). Aug. 4, 1923. Drawings to Specification. Artificial lines. - In an artificial line for balancing an inductively-loaded cable, and comprising a network of which each section is provided with lumped inductance and capacity, each section is of such an equivalent length that oscillatory currents impulsively produced therein by the local transmitter are of frequencies which do not disturb appreciably the local receiving- device. The sections remote from the receiver may each be of such an equivalent length, that the resulting oscillatory currents would produce such disturbance but for their remoteness.
