Title: Process for Producing Metallic Coatings.
Inventor: STOLLE GEORG
IPC: C23C4/12
Filed: 1915-02-19
Abstract: 100,322. Stolle, G. Feb. 19, 1915. Coating.-In coating surfaces by spraying atomized molten or vaporized metal against the article, oxidation of the coating-metal is prevented by cooling the particles before they reach the air. For this purpose, the spraying-pipe c, which receives the metallic particles from a vaporizing-chamber b, may be ribbed as shown at d; or the pipe may pass through a water tank. Nozzles of the kind described in Specification 2692/15 may be used.
Patent GB-994621-A (GB)
Title: New derivatives of heparin and processes for their preparation
IPC: C08B37/10
Filed: 1964-01-16
Abstract: The invention comprises benzyl heparinate. A long-chain quaternary ammonium salt of heparin is benzylated by reaction with a benzyl halide.  The resulting quaternary ammonium benzyl heparinate salt may be converted to alkali metal benzyl heparinate salt by treatment with an alkali metal carboxylate or to free acid benzyl heparinate by treatment with an acid ion-exchange resin. In an example, the neutral heparin salt of Hyamine 1622, Specification 904,112, is treated, in tetrahydrofuran, with benzyl bromide, and the resulting Hyamine 1622 benzyl heparinate salt is precipitated with methanol.  An aqueous solution of the product is treated with methanolic sodium acetate to form sodium benzyl heparinate salt.  The benzyl heparinates and non-toxic salts thereof possess anticoagulant and antilipaemic activity.ALSO:Pharmaceutical compositions comprise the benzyl ester of heparin or non-toxic salts, e.g. sodium and potassium salts, thereof, together with a carrier.  The compositions possess anticoagulant and antilipaemic activity and may be administered rectally or by intramuscular, subcutaneous or intravenous injection for the treatment of thrombosis, phlebites, arterites circulatory disorders and cardiac disorders.  The preferred compositions are suppositories when the carrier is a suppository base, and injectable solutions when the carrier is a sterile aqueous medium. Specification 904,112 is referred to.

Abstract: 787,717. Compressing gases: injectors. SEBAC-NOUVELLE SOC. ANON. Jan. 24, 1956 [Jan. 28, 1955], No. 2330/56. Classes 8(1) and 71. A compressor comprises a ring of separate injector nozzles 2, Fig. 1, each supplied with combustible working fluid under pressure through a duct 14 and a slot 11, Fig. 2, so as to induce a combustion supporting gas into the throat 8, means to ignite the resulting mixture as it is discharged from the divergent portion 9 of each nozzle, a plurality of troughs 3, Fig. 3, serving to guide the hot combustion gases round the ring of nozzles and a plurality of divergent deflectors 5 surrounding the troughs 3 and nozzles 2 which serve to convert kinetic energy of the hot gases to potential energy and to discharge them to a header 6. As shown, liquid hydrocarbon under pressure is forced from a manifold 1 along each duct 14 to an annular chamber 10 of each nozzle 2 and through the orifice 11 thereof. A strainer 16 prevents backfiring and the temperature of the hot combustion gases is reduced by forcing water from valved ducts 42 into the nozzles at the induced gas, e.g., air inlets. In a modified nozzle 21, Fig. 8, the working jet 11<SP>1</SP> is located further from the air inlet end of the nozzle and in a further modification the water is injected through a ring of holes in the cylindrical wall of the nozzle at the air inlet end. Hydrocarbon vapour instead of liquid may form the working fluid and to this end liquid hydrocarbon is vaporized in a duct located at one focal point of an ellipse formed by the crosssection of an internally reflecting surface ; the other focal point being occupied by a radiant heat source.

Patent GB-675793-A (GB)
Title: Stabilized starch derivatives
IPC: C08B31/04
Filed: 1950-02-01
Abstract: Starch ethers and esters of poly-beta-hydroxy aliphatic acids are obtained by reacting starches with lactones of the acids. Alkaline reaction conditions give esters and neutral or acid conditions yield ethers (c.f. Group IV(b)).  The term starch includes its conversion products or derivatives which contain free hydroxyl groups.  Many lactones are specified, representative being beta propio-, isobutyro- and valero-lactone.ALSO:Starch reacted with an inner ester of a beta hydroxy aliphatic acid yields esters under alkaline conditions and ethers under neutral or acid conditions.  Starch or its conversion products or derivatives which contain free hydroxyl groups may be used.  Inner esters specified are beta-propio-, -butyro-, -isobutyro-, -valero- and -iso-valero-lactone.  Room or higher temperatures may be used.  The products form aqueous dispersions of substantially the same viscosity as those obtained from the untreated starch but retain their clarity and viscosity for longer.  Desirably moisture is present during reaction, e.g. a minimum of approximately 10 per cent, based on dry weight of starch.  Quantities of inner ester mentioned are 0.1 and 300 per cent of the weight of dry starch, higher proportions leading to a product which absorbs and swells in alcohols, e.g. glycerine and glycols.  The lactone may react with the substituent of the starch to yield an ether or ester of a polyacid. The lactone may be added to an aqueous dispersion of the starch. Preferably the ratio of starch/water is not in excess of 5/1. Inorganic and organic alkalies are specified, preferably in amounts of 0.1-3 per cent of the starch.  Large amounts of lactone, e.g. 10 per cent, are added at intervals as is the alkali so as to maintain a pH of about 10.  The lactone may also be blended, e.g. by spraying, with an ordinary air-dry starch which may contain the alkali.  In examples: (1) an ungelatinized thin-boiling corn starch, (2) tapioca British gum, (3) and (5) corn starch, and (4) thin-boiling potato starch are treated in aqueous caustic soda suspension with beta-propiolactone; (6) corn starch is made alkaline by treatment with sodium hydroxide, dried to a moisture content of 10-15 per cent, and treated by spraying with beta-propiolactone; (7) wheat starch suspended in aqueous caustic potash is treated with beta-butyro-lactone; (8) corn starch in aqueous suspension is treated with beta-propiolactone; and (9) corn starch is treated in hydrochloric acid suspension, pH 3.0, with beta-propiolactone.  The products may be marketed as mixtures of the reactants, the reaction then taking place on addition to water.
