Abstract

419,295. Compound glass. SPROXTON, F., Brantham Works, Manningtree, Essex, and BRITISH XYLONITE CO., Ltd., Hale End, London. May 4, 1933, No. 13072. Drawings to Specification. [Class 140.] The reinforcing layer of laminated or safety glass consists wholly or partly of a sheet of light-polarizing material made by arranging in a transparent or translucent material transparent reflecting lamellar particles which are regularly arranged so that their surfaces lie in parallel planes inclined to the surface of the material at an angle greater than the angle made with the normal by a refracted ray entering the transparent material at grazing incidence.
