PL PLLongest term of the patent until November 17, 1941 Patent No. 6312 describes an explosive cartridge or charge containing liquid air, a flammable metallic powder and a flammable organic absorber that can be infused with liquid air. The present invention relates to the manufacture and use of this type of gas. an explosive in which a metallic powder or a mixture of several combustible metallic powders is replaced partially or wholly with dust from blast furnaces, mixed with cooling salts, such as sodium chloride or carbonate, and the so-called the abovementioned is particularly suitable for coal mines. In order to avoid the formation of carbon monoxide when the cartridge explodes with liquid air filled with liquid air, the cartridge is coated with a non-porous material such as asbestos paper or asbestos paper. non-flammable feathers. In some cases, moreover, for the sake of protection, they are wetted with cooling salt solutions. To increase the crushing power of the explosive, it is sufficient to add a small amount of any hydrocarbon. PL PL
