Title: Edible food casing dyed with an edible dyestuff and process for its manufacture
IPC: A22C13/00
Filed: 1973-03-15
Abstract: 1429662 Dyed sausage casing NATURINWERK BECKER & CO 15 March 1973 [15 March 1972] 12436/73 Heading A2B An unfilled edible food casing comprises an edible casing material dyed with a dyestuff which is embedded in protective material to discourage transfer of the dyestuff to contiguous objects and to protect the dyestuff against attack by aqueous media. The edible casing material may comprise collagen, polyvinyl alcohol or alginate. The dyestuff may be protected by cross linking a suitable protective substance, which may be cross-linked under the action of heat and/or of curing or tanning agents incorporated in the dyestuff solution. Such substances include proteins, cellulose or cellulose derivatives, pectins and alginates. Other materials which may be cross linked by tanning agents include cellulose derivatives. gum arabic and guar gum: these may be crosslinked by glutaraldehyde, glyoxal or aluminium sulphate. A further method is to embed the dystuff in a hydrophobic substance such as a fat and emulsifying this in the casing composition. The preferred method is to apply the dyestuff to an edible carrier material such as cellulose and cellulose derivative fibres or powders, or powdered starch, collagen or casein and then encapsulating the dyed carrier material in a hydrophobic material such as a synthetic glyceride mixture, sunflower seed oil, beef suet, lard or a high melting fat or wax such as paraffin or beeswax. If desired an emulsifying agent such as ammonia, hydrolysed lactalbumin or lecithin may be added to the aqueous phase before mixing with the collagen paste prior to extrusion as a tube.

Title: Improvements in or relating to synthetic resinous compositions
IPC: C09D191/00
Filed: 1937-05-06
Abstract: 500,348. Synthetic resinous compositions. PINCHIN, JOHNSON, & CO., Ltd., BEVAN, E. A., and TERVET, J. R. May 6, 1937, No. 13004. [Class 2 (iii)] [Also in Group III] A process for preparing synthetic resinous compositions consists in heating to above 180‹ C., a mixture of an oil or oils containing less than ten per cent of bodies having conjugated double bond linkages, or of the acids derived from such oils by hydrolysis, with a carboxylic acid or a derivative thereof containing the alpha-# enal grouping -C=C-C=O, | or with a carboxylic acid which readily gives rise to a compound having such grouping on heating, in which at least one molecular proportion of such carboxylic acid or such derivative is employed for each molecular proportion of oil or for each three molecular proportions of the acid derived from such oil, as the oils are triglycerides. Examples of such oils are triglyceride esters of unsaturated fatty acids which have twelve or more carbon atoms, such as linseed, soya bean, cotton seed, sesame, olive menhaden and sardine oils. Examples' of the acid containing the alpha-# enal grouping are maleic and cinnamic acids. In an example, 140 parts by weight of varnish linseed oil were mixed with 49 parts by weight of maleic anhydride in a glass vessel through which a stream of carbon dioxide was passed. The whole was immersed in an oil bath and heated to 220‹ C. for two hours. A clear strawcoloured viscous mass was obtained of acid value 117, iodine value 105 (original iodine value of the oil was 185). The product is readily compatible with nitrocellulose and yields a flexible tough film with good adhesion to smooth surfaces. If 50 parts of varnish linseed oil are heated to 220‹ C. with 34 parts by weight of maleic anhydride, a hard brittle resin results, which is also compatible with nitrocellulose. Other examples describe the preparation of resins from linseed oil, soya bean oil, olive oil or cotton seed oil with maleic anhydride, the dibutyl ester of maleic acid or malic acid, all of which are compatible with nitrocellulose and readily soluble in aromatic hydrocarbons. The products range from viscose oils to hard brittle resins depending on the degree of unsaturation of the fatty ester or acid, and the proportion of maleic anhydride or like compound. The viscous oil products have quick-drying properties.

Title: Manufacture of ortho-oxyarylcarboxylic acid--a-naphthylamides
Filed: 1951-06-05
Abstract: b -Naphthylamides of o-hydroxyarylcarboxylic acids (including those which, besides the aryl nuclei, contain heterocyclic rings) are manufactured by condensing an o-hydroxyarylcarboxylic acid (advantageously in the form of a salt) or an o-hydroxyarylcarboxylic acid halide with 2-aminonaphthalene-1-sulphonic acid or a salt thereof.  The condensation may be carried out in an inert solvent (e.g. a homologue of benzene or a chlorinated or nitrated derivative of benzene or its homologues), with or without the addition of acid-binding agents (e.g. sodium or calcium carbonate or tertiary amines), or with the use of such amines as solvents.  If the o-hydroxyarylcarboxylic acid is not used in the form of a previously prepared halide, it is necessary to add a condensing agent (e.g. thionyl chloride, phosphorus pentachloride or especially phosphorus trichloride, which last may be used in less than an equimolecular proportion).  Minor amounts of o-hydroxyarylcarboxylic acid 2-naphthylamide-1-sulphonic acids are obtained as bye-products, and may be converted to the desired b -naphthylamides by boiling with a mineral acid.  In examples: (1) 2:3-hydroxynaphthoic acid is heated with 2-aminonaphthalene-1-sulphonic acid in chlorobenzene in the presence of sodium hydroxide and phosphorus trichloride; (2) the same reactants are heated in dimethylaniline in the presence of phosphorus trichloride; 2:21-dinaphthylamine-3-carboyl-211-naphthylamine is obtained as a bye-product; (3) the solvent in (1) is replaced by toluene, and sodium carbonate is added as well as sodium hydroxide; (4) both alkalies in (3) are omitted; (5) the 2:3-hydroxynaphthoic acid in (3) is replaced by salicylic acid; (6) the preformed sodium salt of 2-aminonaphthalene-1-sulphonic acid is heated with 2-hydroxy-3-naphthoyl chloride in chlorobenzene in the presence of sodium carbonate.  Additional o-hydroxyarylcarboxylic acids specified are 2-hydroxycarbazole-3-carboxylic acid and 3-hydroxydiphenylene oxide-2-carboxylic acid.ALSO:A blue-violet azo dyestuff is obtained by coupling diazotized p-nitraniline with 2 : 2\sv-dinaphthylamine-3-carboyl-2"-naphthylamine of the formula <FORM:0700024/IV (c)/1>

Abstract: 849,972. Semi-conductor devices. ENGLISH ELECTRIC CO. Ltd. May 1, 1957 [May 1, 1956], No. 13367/56. Class 37 A rectifier unit comprises a semi-conductor rectifier element and a resistance mounted in parallel with the rectifier element and arranged to be cooled by a fluid coolant flowing through the assembly. In the embodiment shown in Fig. 1 the resistor is in the form of a tube of conductive rubber or polyvinylchloride 27 through which coolant flows from an electrode assembly in contact with one side of the rectifier element to a basically similar electrode assembly in contact with the opposite face of the element. The first electrode assembly comprises a brass sleeve 10 housing a copper body 15 provided with an annular groove 19 which communicates through radial passages 24 with an internally threaded axial hole 19. In other the electrode assembly the copper body has an externally threaded axial extension 22 adapted to screw into the internally threaded axial hole of the first electrode of an adjacent unit. The electrode assemblies are insulatedly joined by an annular metal and glass seal 12, 13, 14 which forms a sealed housing for a rectifier element consisting of an indium body 18 fused to an N type germanium wafer clamped between the two electrode assemblies. In modified forms of the invention the tube joining the electrode assemblies is of insulating material and the resistance in the form of a helix of wire inserted into the tube and allowed to expand against its inner wall, or of wire wound around the outside of the tube. The unit is expressly designed so that it may be mounted in series with similar units as shown in Fig. 3 between a pair of bus-bars 32, 33. In such an assembly the resistors serve to equalise the inverse potentials across the individual rectifier units. The externally threaded electrode of one of the end units passes through bus-bar 33 and is clamped thereto by nut 35 and to a coolant inlet pipe 36 by a union 37. At the other end of the assembly the connection to bus-bar 32 and to coolant outlet pipe 41 is through the intermediary of a centrally flanged adaptor 38 threaded at both ends. Washers 31, 39 are provided between the flanges of the electrodes of adjacent units to prevent leakage of coolant fluid.
