Title: Improvements in Nitrated Carbo-hydrates.
Inventor: HOUGH ARTHUR
Filed: 1904-06-03
Granted: 1904-09-01
Abstract: 12,627. Hough, A. June 13, A.D. 1903, [date applied for under Patents Act, A.D. 1901]. Explosives. - A nitro-cellulose, having a constitution corresponding to the formula C12H12 (NO2)8O10 and of great explosive power and stability, is formed by nitrating starch with acids of great strength, the strength being maintained during the nitrating process. Corn starch free from alkali is used, after carefully drying at about 275‹ F., by steam heat under agitation, and cooling down to atmospheric temperature. A mixture of three parts of nitric acid containing 95 per cent. of monohydrate, and two parts of sulphuric acid of 98 per cent. strength is heated with sufficient Nordhausen sulphuric acid to bring both the nitric and sulphuric acids up to 100 per cent. and to leave about 2 per cent. of free sulphuric anhydride present. The mixture is stirred and then cooled. The starch is added to this mixture by forcibly injecting it as a fine powder, sulphuric acid containing free sulphuric anhydride being also injected in quantity sufficient to maintain about 2 per cent. of free sulphuric anhydride. The temperature should not be below 45‹ F., and should be maintained as uniform as possible. The reaction is complete in about 10 minutes. The reaction product is separated by filtration &c., and the acid, after bringing up to strength, is used again. If sulphuric acid is present in excess, the nitric acid may be distilled off. The nitrated product is washed with water under agitation, the acid neutralized by sodium carbonate &c., and the mass filter-pressed. The cakes are rendered stable by removing any hexanitrate present by means of a hot solulion of ammonium hydrate. The pure product is insoluble in alcohol, ether, or dilute ammonium hydrate either hot or cold, and is ouly soluble with difficulty in concentrated sulphuric acid, but is soluble in ether-alcohol and acetic ether. It is an orange-yellow powder, silky to the touch, and non-crystalline.

Abstract: 16,822. B÷hm, H. July 30. Cans; cans, opening.-Cans for containing preserved food and other substances are constructed with separate chambers to contain chemicals which, when mixed, produce heat so as to heat the preserved f o o d &c. before use. The heating - substances mentioned are lime and water. A number of forms are described. In Fig. 1, the lime is shown enclosed in a side jacket b and the water in a lower chamber c, the material preserved being in a central chamber a. The water is let into the lime by means of perforations made by a sharp instrument as marked at x. In another form, the water is contained in a tube which may be broken, perforated, or opened by means of a stopper withdrawn from the outside. The lime may be contained in a corrugated tapering chamber entering from above or below into a cylindrical chamber containing the food ; the water in this case is placed in a chamber above or below the lime. When inserted from the top, the lime and water chambers are attached to the lid. The food tin may be inserted into and project above the top of an annular lime chamber, the water being below. The lime and water chambers may be formed together and fit on to the food chamber, the joint being made by a soldered band which is stripped off for opening. Fig. 14 shows a further form in which a can-opener v is passed through the lower part of the water chamber c, the outer end resting in a recess b<1> in the outer case. The cans may be surrounded by a heat-insulating jacket consisting of two encircling pasteboard sheets, of which the inner is corrugated and secured to the outer one, which is smooth.
