Abstract
9551. Sa³bermann, S. May 8. Incandescent gas lamps.-Mantle fabrics are prepared from threads spun from a mixture of from 10 to 15 per cent. by weight of cotton fibres to 90 to 85 per cent. of asbestos fibres, or asbestos may be used alone when fibres can be obtained sufficiently long in the staple to be spun into fine threads without knots or protuberances being formed therein. Either these or ordinary mantles can be used with impregnating-solutions containing salts of calcium with from 0À3 to 1 per cent. of cerium nitrate, or 98 to 99À5 per cent. of thorium salt and 0À5 to 2 per cent. of cerium salt, or similar proportions of calcium and cerium salts, and salts of zirconium or thorium may be added to the solution of calcium and cerium salts. When a solution of calcium and cerium salts is employed, the mantles are incinerated immediately they have been dried. The illuminating power of mantles is increased by dipping the finished mantle in a solution containing 5 to 10 per cent. of thorium and cerium salts, and again drying and incinerating.
