Abstract

426,144. Controlling apparatus by light. GENERAL ELECTRIC CO., Ltd., Magnet House, Kingsway, London, and MYERS, C., c/o General Electric Co., Stoke, Coventry. Nov. 22, 1933, No. 32577. Drawings to Specification. [Class 40 (v)] [See also Group XXXVIII] In a telemetering system of the type in which signalling impulses are produced by a photo-electric cell subjected to an interrupted beam of light, the photo-cell, which may be of the gas-filled type, is enclosed in a casing having a slot of less width than that of the slots of the interrupting disc so that squarefronted light impulses are transmitted to the cell. Reference has been directed by the Comptroller to British Specifications 339,146, [Class 40 (i)], 383,302 and 409,302, [both in Group XXXVIII], and U.S.A. Specification 1,878,658.
