Abstract
1462144 Retrodirective reflectors AMERACE CORP 5 April 1974 [24 April 1973] 32714/76 Divided out of 1462143 Heading G2J Retrodirective cube corner reflectors capable of reflecting light back to the source are made in a mould from a matrix which is electro-formed on a surface presented by a plurality of pins grouped in a bundle. Each pin comprises an elongated shank of polygonal outline shape and having a longi- tudinally extending pin axis, and a cube corner formation at one end of the shank having a cube axis, which is inclined to the pin axis at an angle of other than zero degrees, the cube corner formation having three mutually perpendicular faces symmetrically arranged with respect to the cube axis and intersecting in three mutually perpendicular edges.
