Abstract

395,053. Wired wireless systems. GENERAL ELECTRIC CO., Ltd.. Magnet House, Kingsway, London, SMART, N. C. and WESTELL, P. L., c/o General Electric Co., Stoke, Coventry. Jan. 29, 1932, No. 2677. Drawings to Specification. [Class 40 (v).] In a carrier current system of telephony and/or supervisory control of the type wherein a plurality of stations are selectively controlled over a carrier channel, each station has a selector which is used to direct incoming signals to the correct apparatus and also to hunt for an apparatus requiring to send a signal. The system described is identical with that described in Specification 395,289. Specifications 359,576, 361,558, [both in Group XXXVIII], 380,539, and 395,045 also are referred to.
