Abstract
297,365. Nienhuis, J. P. March 17, 1927. Explosives.-Oil-pitch or asphalt-pitch, or the like. with or without charcoal or the like, is used in conjunction with potassium nitrate and sulphur for the manufacture of powder suitable for fuzes and for blasting or military operations where slow action is required. The proportions are potassium nitrate 73 per cent, sulphur 15 per cent, and the pitch compound 12 per cent. The pitch is melted and strained, and after cooling is crushed before incorporation with the potassium nitrate and sulphur which are also powdered beforehand. The mixture is heated to a temperature between 150‹ C. and 250‹ C., and after this may be subjected to pressure while still hot before being finally grained and sifted into various sizes. The higher the temperature used, the quicker the rate of burning of the fuze finally prepared from the powder ; and the greater the pressure used, the slower the fuze. The ingredients may alternatively be mixed by the ordinary wet process.
