Title: A process for removng fat from bones
Inventor: CROWDER JENNINGS CLIFTON
IPC: C11B1/14
Filed: 1962-07-24
Abstract: A continuous process for defatting bones comprises breaking the bones by slowly applying pressure thereto (e.g. in a mill), contacting the thus-broken bones with hot water (e.g. 120-200 DEG  F.) partially to defat the bones, draining off the water, repeating the breaking and water-treatment stages at least once in such a manner that the bones have an average particle size of 3/16 -\ba3/4 inch, draining off the water used in the final water-treatment stage, and drying the bone material to produce a dry bone material substantially free from fat. Preferably the process is carried out in three stages, the average particle size of the bones after each stage being 2 inches, 1 inch and 1/2 inch respectively the time taken for the whole operation preferably being 25-30 minutes.  High quality fat and meat are recovered from the water, and the resulting bone material contains high quality gelatin.  Specification 902,899 is referred to.

Title: Improvements in or relating to polyamide resins and compositions containing them
Inventor: CRAWFORD RAYMOND VINCENT
IPC: C08G69/26
Filed: 1964-07-15
Abstract: A polyamide is prepared by reacting a polyamine with an adduct of (a) a mixture of fatty compounds containing, as the major component, a mixture of free or combined positional or geometrical isomers of conjugated polyunsaturated fatty acids, or amides or esters thereof, and in addition other conjugated or non-conjugated unsaturated fatty acids or amides or esters thereof and (b) an amount of acrylic acid or an alkyl acrylate equivalent to the conjugated diene content of (a).  Polyamines specified are ethylene diamine, diethylene triamine, triethylene tetramine, and penta-ethylene hexamine.  The fatty compounds may be dehydrated castor oil acids, e.g. linoleic acid, or may be produced by isomerization, catalysed by sulphur or alkali, of sunflower oil or soya oil. The adduct may be formed in the presence of up to 20% of another dibasic acid, e.g. adipic, sebacic, azelaic or phthalic acid or up to 50% of a mono-carboxylic acid, preferably containing 6-18 carbon atoms, e.g. oleic or palmitic acid. The polyamide produced may be a liquid or a solid and may be mixed with an epoxy-resin, applied in a coating to a substrate, allowed to dry and optionally heated to cure the epoxy-resin. In Example (1) 2,6-di-tert-butyl-p-cresol is mixed with isomerized sunflower oil and a stoichiometric excess of acrylic acid, the excess acid being recovered as methyl ester by distillation after the adduct is formed. In another example a bisphenol A/epichlorohydrin condensate dissolved in a methyl isobutyl ketone/xylene /ethylene glycol monoethylether/ethylene glycol monoisopropyl ether mixture is mixed with a xylene/ethylene glycol monoethyl ester solution of a polyamide and heated to cure.ALSO:Aluminium panels and tin plate are coated by dipping with a solution of an epoxy-resin and a polyamide curing agent in an organic solvent and the coating dried by heating.  In Examples, an epoxy-resin derived from bisphenol A and epichlorohydrin is used in conjunction with a polyamide derived from an adduct of acrylic acid and soyabean or sunflower oil together with a polyamine, e.g. ethylene diamine, diethylene triamine, trethylene tetramine and/or penta-ethylene hexamine and optionally phthalic, palmitric, oleic and/or adipic acid.  Solvents are methyl isobutyl ketone nylene, ethylene glycol monoethyl ether and ethylene glycol mono-isopropyl ether.

Abstract: 927,339. Making electric cables; welding by pressure. STANDARD TELEPHONES & CABLES Ltd. Aug. 16, 1961 [Oct. 6, 1960], No. 29599/61. Divided out of 926,740. Classes 83 (2) and 83 (4). [Also in Group XXXVI] In sheathing an electric cable, a metal strip is longitudinally folded round the cable with its longitudinal edges bent away from the cable, the edges are cold-pressure welded in a continuous line weld and the edges are folded on to the sheathing so that the line weld lies between the fold and the ends of the edges. A strip of aluminium 3, Fig. 1, fed from a reel 4 is folded around a cable 1 fed from a reel 2 by a roller or die tool 5 so that the edges 6, 7, Fig. 3, are bent away from the cable. The edges which are scratch brushed are passed between a pair of rollers 8, one having a flat cylindrical surface and the other a circumferential ridge 9 which form a line weld 10, Fig. 3. Rollers 11, 12 then fold the edges down to the sheath with the weld beyond the bend and a machine 16 regulated by a capacitance measurer 18 extrudes an outer thermoplastic sheathing over the aluminium. The sheathed cable is drawn by caterpillar capstans 13, 15. In a modification a sinuous line weld 19, Fig. 5, may be formed. Several aluminium sheaths may be provided, the pairs of welded edges being spaced from one another. A second ridge may be formed on the roller 8 to produce a slight deformation below the weld so that the edges may be firstly bent about the deformation before being bent on to the sheath. The aluminium strip may be transversely corrugated by meshing rollers 22, Fig. 1, before being folded round the cable with the corrugated edges interlocked. Alternatively, the edges may be left uncorrugated. A cotton, fibre glass, plastic or metal filament 23, Fig. 1, may be wound round the cable before the strip is folded about it and/or a filament 25, Fig. 1 may be wound over the sheath. Instead of a filament a polythene or aluminium strip formed with one or more ridges may be used. A cotton, fibre glass, aluminium, nylon, polythene or rubber filament 30, Fig. 13, may be fed from a reel 31, Fig. 1, against the sheath just before the edges 6, 7 are folded on to the sheath. To provide an electrical screen one or more aluminium strips may be helically or longitudinally applied to the sheathed cable, e.g. an open corrugated sheath with flat edges is folded about the sheathed cable with a gap between the edges to expose the folded welded edges. The edges of the outer sheath may be locked in a folded seam or located diametrically opposite the folded welded edges.
