Abstract

511,311. Electric control systems. GENERAL ELECTRIC CO., Ltd., and FLETCHER, J. Y. May 4, 1938, No. 13233. Drawings to Specification. [Class 40 (i)] Apparatus such as street lamps or water heaters associated with an electric power substation or feeder is controlled from a central point by wireless which causes the superimposition on the supply at the substation or over the feeder of control current of substantially audio-frequency for the operation of relays such as the tuned relay described in Specification 491,980, [Group XXXVII]. The radio or modulation frequency may determine the selection of the power station and the operation to be performed, the audio-frequency applied to the power lines also being different for different operations. The Provisional Specification describes also the direct control of apparatus by wireless.
