Abstract

918,015. Reflection reflectors. WESTBROOKE, W. G. F. Feb. 16, 1959, No. 5245/59. Class 97 (1). A reflex reflector comprises triple reflector elements 2 on a spherical concave surface 4 distributed round the centre in three or more radiating sections with those in each section differently angularly orientated about their axes from those in adjacent sections, said elements defining a boundary with a number of straight sides which is greater than the number of sections. The elements are preferably surrounded by a ledge 1 and a raised rim 5.
