Abstract

569,263. Electric incandescent lamps. REICH, O. E. July 13, 1943, No. 11357. [Class 39 (ii)] A reflecting surface which may be translucent is formed on a finished electric lamp by spraying or otherwise applying in suspension in a liquid or analogous medium a material unaffected by heat: the coating is subsequently baked say at 400‹ to 440‹F. Chalk or other calcium carbonate suspended in water glass (sodium silicate) is suggested.
