Abstract

340,551. Optical reflectors. GENERAL ELECTRIC CO., Ltd., Magnet House, Kingsway, London, WILSON, G. H. and BEGGS, S. S., of General Electric Co., Wembley, Middlesex. Sept. 2, 1929, No. 26634. Drawings to Specification. [Class 97 (i).] A reflector having no axis of symmetry is designed so that rays emitted by a light source in any one of a class of planes containing a certain line passing through the light source lie after reflection in a class of parallel planes. The Specification gives a mathematical treatment of the above principle of design.
