Title: "improvements in or relating to the processing of acid nitrated organic products"
IPC: C06B31/00
Filed: 1954-07-02
Abstract: In a method of processing acid nitrated organic products, such as acid nitroglycerinenitroglycol, the acid nitrated organic product is neutralized by adding a mixture of ammonia and/or an organic base and ammonium nitrate.  Suitable bases are urea, aniline, guanidine, naphthylamine or hexamethylenetetramine.  The nitration of benzene, sorbitol and toluene is also mentioned. Ammonium nitrate may first be added to the acid nitrated organic product which is afterwards neutralized by the addition of a mixture of ammonia and/or an organic base and ammonium nitrate. Part of the ammonium nitrate can be replaced by another inorganic nitrate such as sodium nitrate.  The base can be used in the form of a molten, preferably eutectic mixture with the ammonium nitrate.  For example, an eutectic mixture of 45 per cent urea, 47.5 per cent ammonium nitrate and 7.5 per cent of sodium nitrate is suitable.  In examples (1) a liquid mixture of anhydrous ammonia and ammonium nitrate containing 20 per cent ammonia is added to a mixture of nitroglycerine (containing nitric acid) with ammonium nitrate; (2) a liquid composition of anhydrous ammonia and ammonium nitrate is added to an acid mixture of nitroglycerine, nitroglycol and nitrosucrose; (3) to a mixture of nitroglycerine and nitroglycol (containing nitric acid) a mixture of ammonium nitrate, sodium nitrate and urea, prepared and kept at 45 DEG  C. is added; (4) glycerol trinitrate and glycol dinitrate containing nitric acid are mixed with ammonium nitrate, urea, hexamethylene tetramine and a compound R.CH (CH3)O.SO2.ONa (where R is alkyl of about 12 carbon atoms); (5) nitroglycerine containing nitric acid is stirred into a mixture of aniline and ammonium nitrate; (6) a mixture of hexamethylene tetramine and ammonium nitrate is added to a mixture of crude nitroglycerine and ammonium nitrate; (7) glycerol trinitrate and glycol dinitrate containing nitric acid are mixed with ammonium nitrate, naphthylamine and water.  In each case the neutralized products are worked up with other ingredients to form explosive compositions (see Group XXI).  Specification 362,175, [Group IV], is referred to.

Filed: 1927-09-14
Abstract: 304,225. Kennedye, C. B. Sept. 14, 1927. Divided on 301,142. Drawings to Specification. Borehole apparatus.-In a well-boring tool with bits inserted in transverse slots in a head, the wall-portions of the slots are highly hardened by heat treatment, the hardness decreasing inwardly in the head, and the bits are heat treated so as to comprise a part of maximum hardness and a part of maximum toughness, the first part being presented to the formation being drilled and the second part forming a backing therefor. This backing wears more quickly than the hardened part, the blades therefore being self-sharpening. The parts of the blades held in the head may be thicker than the projecting parts, and the latter may have reinforcing ribs. The hardened parts of the blades may be produced by embedding the blades in fine sand, the parts to be hardened being left exposed; the exposed parts are then subjected to the action of a carburizing agent, and after tempering the blades and treating them in a hardening furnace, the carburized portions only are quenched in cold water. Specification 301,142 is referred to.
