Abstract

15,957. Kohl, G. July 21. Incandescent gas &c. lamps.-Mantles possessing great strength, durability, and light-emitting properties are prepared by impregnating the skeletons of cotton or other vegetable fibre with a strengthening-solution containing 2 grammes of nitrate of zinc, 1À2 grammes of nitrate of tin, 1 gramme of nitrate of bismuth, 1 gramme of borax, and 2 grammes of calcium nitrate to 1 kilogramme of water, and drying at a high temperature before immersing them in the solution of the salts of the incandescing materials. This second solution contains 400 grammes of thorium nitrate, 2 grammes of cerium nitrate (free from didymium), 0À4 gramme of barium nitrate, 3À2 grammes of strontium nitrate, 0À12 gramme of indium nitrate, 0À04 gramme of gallium nitrate, and 0À24 gramme of samarium nitrate to 1 kilogramme of water. The mantles are then rapidly dried and incinerated.
