Title: Improvements in or relating to the production of nitrocellulose
IPC: C06B23/00
Filed: 1946-03-14
Abstract: In the production of nitrocellulose soluble in nitroglycerine, the final washing is carried out using an aqueous composition of an organic compound having a long carbon chain of open or closed structure, which said compound is a liquid or soft solid which will not be volatilized during the drying of the nitrocellulose, is soluble or dispersible in nitroglycerine and is a non-solvent for nitrocellulose and drying the thus treated product by mechanically removing any of the liquor expressible therefrom and evaporating water from the resulting damp nitrocellulose.  The long chain should have at least eight carbon atoms and the compound should preferably be a non-accelerant of the rate of solution of nitrocellulose in nitroglycerine.  The process produces a nitrocellulose which goes into solution in a uniform manner and the final product on extrusion gives a cord possessing the rough surface characteristic of a good blasting gelatine. Examples of suitable organic compounds which are liquid and non-wetting agents are shale oil, rosin oil and castor oil, and these are employed as an aqueous emulsion in the final wash so that the dry nitrocellulose retains about 5 per cent of its weight of the oil.  Examples of suitable organic compounds which are liquids or soft solids and wetting agents are turkey red oil, sulphonated methyl oleate and ethylene oxide condensation products of long chain alcohols and amides.  These compounds are employed in such concentrations that the dry nitrocellulose retains about 2.0 per cent of its weight of the organic compound.  Wetting agents give nitrocelluloses which are more readily dispersed, but non-wetting agents reduce the dustiness of the dry nitrocellulose, so in preference a combination of both is used so that the dry nitrocellulose retains about 1.5 per cent of its weight of wetting agent and about 3.5 per cent of its weight of non-wetting agent. In an example, blasting soluble nitrocellulose (N content 11.95 to 12.25 per cent) is finally washed with an aqueous emulsion of 7 per cent rosin oil in a 3 per cent solution of sulphonated methyl oleate, centrifuged to a water content of 35 per cent and dried by evaporation.  The so-prepared nitrocellulose may be used in the manufacture of blasting explosives (see Group XXI).

Abstract: 529,772. Steel. BRASSERT & CO., Ltd., H. A. (Brassert, H. A.). April 17, 1939, No. 8568. [Class 72] In the production of steel by the acid or basic Bessemer process, the molten metal is subjected, after all blowing operations have been concluded, to a vigorous boil produced by reaction with iron oxide or iron oxide and carbon added to the bath in order to remove nitrogen and other gases present. The blow may be continued until the carbon and phosphorus contents are below the desired amount and carbon then added or when using the basic process the blow may be discontinued when the metal contains more phosphorus than the desired amount and then both iron oxide and carbon are added. When using the acid process, the blow may be discontinued when the metal contains more carbon than the desired amount and then iron oxide is added. The necessary heat to carry out the process may be supplied by using a pig iron of relatively high silicon and/or manganese content, by pre-heating the pig iron, supplying heat to the converter by means of a gas or oil flame or by making the usual alloy additions in liquid form. The converter may have the form described in Specification 507,200, and then when the blowing has been ended, the converter is turned down so as to form a shallow bath of metal before the boil is produced. Specification 518,212 also is referred to.
