Title: Improvements in or relating to the compression of heels for boots or shoes
IPC: A43D83/00
Filed: 1937-12-11
Abstract: 507,224. Heel-compressing machines. BRITISH UNITED SHOE MACHINERY CO., Ltd., and CLARKE, T. B. Dec. 11, 1937, No. 34365. [Class 17 (i)] In a heel-compressing machine of the kind described in Specification 22839/02, [Class 17], the links actuating the side moulds are modified so that these parts first approach one another yieldingly, to centralize a heel between them, and, later, transmit a positive pressure. A carrier 20 for a side die slides vertically and horizontally under the restraint of a link engaging an adjustable pivot pin 12 by a slot, as described in the prior Specification. At the inner end of the slot is a spring plunger 36 reducing the lost motion provided by the slot and causing the dies to approach each other before this lost motion has been taken up. The outer end of the link houses a spring urging the link outwardly to a limit determined by a pin 34. In a modification, the link is in two telescoping parts 116, 117 connected by friction plates 121, 122 urged together by springs 123 on pins 119, 120, lost motion being provided by slots in the friction plates and the member 116. As the side die descends, the parts of the link are extended, so that as the side dies rise again they close on the heel to centre it before the heavy moulding pressure is exerted. Specification 502,825 also is referred to.

Abstract: 390,780. Ink. KURZ, H., 2, Geyergasse, and ALBERT, K., 2, Thugutstrasse, both in Vienna. Dec. 5, 1932, No. 34478. Convention date, Dec. 3, 1931. [Class 146 (iii).] Intaglio printing-inks are prepared with a binder formed of an alkali solution of resin without the addition of a water-soluble organic solvent, the alkali being present partly as fixed alkali and partly as ammonia. In order to facilitate the retention of the pigments in suspension, colloids such as casein or glue may be added, and a defrothing agent such as an ethereal oil is used. Colophony is preferably used, but other resins such as shellac which yield soluble ammonium compounds or the ammonium compounds of which are peptonized by the alkali resinate present, may be added. The fixed alkali may be caustic soda or caustic potash. According to an example, colophony is dissolved in a mixture of caustic potash and ammonia, and is stirred with water to which a small amount of turpentine oil has been added. Casein may also be added. Pigments are then ground into the mixture. If pastes are used as colouring materials, allowance for the contained water is made during the preparation of the binder.

Title: Improvements in or relating to esters of acylated 3,5-diaminotriiodobenzoic acid
IPC: A61K49/04
Filed: 1954-11-30
Abstract: The invention comprises compounds of the general formula <FORM:0779500/IV(b)/1> wherein R is an alkyl group containing from 1 to 6 carbon atoms, and R1 and R11 are alkanoyl groups, which may be the same or different, containing from 1 to 6 carbon atoms, and their preparation by acylation of the corresponding diamino compounds or, when the group R1 and R11 are different, the corresponding monoamino-monoacylamino compounds.  The acrylation is carried out by heating with the appropriate acid, acid anhydride or acid halide.  It is pre-ferable to use formic acid for the formation of the formyl derivative and the appropriate acid anhydride or acid halide for the formation of higher derivatives.  The acylation is promoted by the addition of a trace of a strong acid such as sulphuric acid, perchloric acid or an organic sulphonic acid.  Examples describe the preparation of (1) the ethyl, methyl, propyl, isopropyl and butyl esters of 3,5-diacetamino-2,4,6-triiodobenzoic acid by acrylation of the corresponding esters of 3,5-diamino-2,4,6-triiodobenzoic acid with acetic anhydride in the presence of a trace of concentrated sulphuric acid; (2) ethyl 3,5-diformamido-2,4,6-triiodobenzoate by heating the corresponding diamino compound with formic acid; (3) ethyl 3,5-dipropionamido-2,4,6-triiodobenzoate by heating the corresponding diamino compound with propionic anhydride or propionyl chloride; the butyramido compound is obtained similarly; (4) ethyl-3-formamido-5-acetamino - 2,4,6 - triiodobenzoate by heating ethyl 3 - amino - 5 - acetamido - 2,4,6 - triiodo benzoate with formic acid; and (5) ethyl 3-propionamido - 5 - acetamido - 2,4,6 - triiodobenzoate by heating ethyl 3-amino-5-acetamido-2,4,6-triiodobenzoate with propionic anhydride. The products are stated to be useful as X-ray contrasting agents. Starting materials.  Esters of 3,5-diamino-2,4,6-triiodobenzoic acid are prepared by catalytic reduction of the corresponding ester of 3,5-dinitrobenzoic acid followed by exhaustive iodination of the resulting 3,5-diamino benzoic acid ester with iodine monochloride in acid solution.  Esters of 3-amino-5-acylamino-2,4,6-triodobenzoic acid are prepared as follows: 3,5-dinitrobenzoic acid is selectively reduced to 3-nitro-5-amino-benzoic acid which is then acylated to a 3-nitro-5-acylaminobenzoic acid.  This is then esterified and the ester is catalytically hydrogenated to give an alkyl 3-amino-5-acrylamino benzoate which is exhaustively iodinated, conveniently with a solution of potassium iodide dichloride (KIbl2).ALSO:A radiopaque agent contains as an active ingredient a compound of the formula <FORM:0779500/VI/1> where in R is an alkyl group containing from 1 to 6 carbon atoms and R1 and R11 are the same or different alkanoyl groups each containing from 1 to 6 carbon atoms.  The active ingredient may be dispersed in a finely divided dust or it may be made into an aqueous suspension with the aid of an emulsifying agent such as carboxymethylcellulose, polyvinyl-pyrrolidone or dextran.
