Abstract

7864. Sanoscop-Glas-Ges. April 4, 1912, [Convention date]. Colour screens; spectacle lenses.-Glass, having the property of absorbing the ultra-violet rays, is produced by adding to the ordinary constituents of glass rare earths of the series thorium, lanthanium, cerium, samarium, erbium, praseodymium, and neodymium. Salts of heavy metals may be added in very small quantities to act as decolourizing-agents. The glass may be used for spectacle and other lenses, lamp shades, mercury-vapour lamp bulbs, &c.
