Abstract
201,121. Soc. Anon. de Dynamite de Matagne. July 18, 1922, [Convention date]. Processes.-A process for moulding rigid casings, especially for cartridges, from cementitious material consists in mixing the material with salts containing water of crystallization and subsequently heating the mixture until the water is set free and hardens the cement. The mixture preferably also contains flame-extinguishing salts, for example calcium fluoride and sodium chloride. A mixture containing 50 per cent plaster, 30 per cent calcium fluoride, and 20 per cent sodium sulphate is poured by means of double funnel into a paper bag surrounding the cartridge so as to leave the ends thereof uncovered, and is subsequently heated to about 40‹ C. until a rigid sheath is obtained.
