Patent GB-336698-A (GB)
Title: Improvements in the manufacture of resinous compounds
IPC: C08G63/668
Filed: 1929-08-03
Abstract: 336,698. Imperial Chemical Industries, Ltd., and Hill, R. Aug. 3, 1929. Ester condensation products.-The blending of nonhydroxylated fatty oils, especially drying oils, with resins obtained by the interaction of a polyhydric alcohol with a polybasic acid or an anhydride thereof is facilitated by replacing some or all of the polyhydric alcohol by the product obtained on treating a polyhydric alcohol with a lower aliphatic aldehyde. In the preferred form of the invention, the crude or purified alcoholaldehyde compound is heated with the acid or anhydride and the fatty oil, with or without the further addition of a polyhydric alcohol, which may differ from that used in the preparation of the aldehyde compound. In another form of the invention, the aldehyde is added to the polyhydric alcohol, polybasic acid or anhydride, and non- hydroxylated fatty oil, and the mixture heated, if necessary under reflux or in a closed vessel, until a homogeneous resinous mass is obtained. It is preferred to use the reflux for paraformaldehyde and a closed vessel for acetaldehyde. The properties of the resins' may be varied by varying the nature and proportions of the ingredients, especially of the aldehyde and the drying oil. Linseed oil is more easily incorporated than tung oil, and mixtures of oils, e.g. of linseed and tung oils, give good results. Varnishes prepared by this process dry rapidly in the air or at elevated temperatures, and the rate of drying may be increased by the incorporation of metallic driers such as cobalt linoleate. The smaller the proportion of aldehyde to glycerol, the harder is the resin and the better the drying properties of the varnish. The resins are well adapted for application in varnish paint technique, and as flexible varnish finishes for rubber, leather, and other goods. In addition to linseed and tung oils, other nonhydroxylated fatty oils such as olive oil, cottonseed oil and other like oils may readily be incorporated by this process. The nature of the products may be varied by the addition of natural or synthetic resins such as colophony, ester gum, copal, phenolformaldehyde or ureaformaldehyde condensation products. In many cases such additions aid the incorporation of the oil. In the examples, glycerol and paraformaldehyde are condensed together, then phthalic anhydride and tung oil, or phthalic anhydride and linseed oil, or phthalic anhydride, tung oil, colophony and glycerol are added, and the mixture is heated until a homogeneous resin is produced.

Title: Improvements in or relating to mechanism for separating hops from leaves, stems and other foreign material
IPC: A01D46/02
Filed: 1938-08-13
Abstract: 506,477. Separating solid materials. STEVENS, A. H. (Clemens Horst Co., E.) Aug 13, 1938, No. 23933. [Class 117] Hops with the leaves, stems, &c. are fed on to an inclined endless pervious belt and air is drawn through the belt to cause the leaves, stems, &c. to adhere thereto while the hops roll down the belt. In the form shown, the belt F runs on drums C, D, E on a triangular framework adjustable for varying the belt inclination and a pair of fans G in a housing H apply suction to the upwardly running part of the belt on to which the material falls from hopper 36. The hops roll down the belt to the receiver 37 and conveyer 38 whereas the leaves, stems and waste material adhere to the belt until they have passed the pervious drum C, when they begin to drop off the belt. The liberation of the stems &c. from the rear and horizontal part of the belt is assisted by the air currents leaving the fans in the direction of the arrows c, the drum E also being made pervious to increase the effect.

Title: Improved process for preparing a granular material coated with an inorganic or organic pigment
IPC: C08J3/20
Filed: 1952-10-01
Abstract: Granular material is coloured by tumbling it with an organic or inorganic pigment in presence of 0.05-2 per cent of a colour-stabilizing agent having the formula R1 X R2 where R1 is a strongly hydrophobic group with a hydrocarbon radicle of at least 10 carbon atoms, R2 is strongly hydrophilic containing at least one group with the formula (CH2CH2O)n (on being larger than 3) and X is a connecting group, e.g. an ether, amine, ester or amide group.  The process is especially suitable for colouring synthetic thermoplastic polymeric material for melt-spinning or injection moulding, e.g. polyamides, polystyrene or glycol terephthalates. The pigments may be inorganic, e.g. titanium oxide, iron oxide, chromium oxide, molybdenum sulphide, indium sulphide, barium sulphate, calcium carbonate, ultramarine, or talc or organic, e.g. the acetate dyestuffs in pigment form.  Preferably the granular material and the colour-stabilizing substance are mixed first and the pigment then added.  The colour-stabilizing agents mentioned are mostly known under Registered Trade Names, e.g. Berol, Tweens or Soromin.  Others mentioned are Ethomene, Ethofat and Ethomid. Chemical formul  are ascribed to these substances.  In the examples (1) cylindrical polyamide grains were mixed in a bottle on rotating rollers with 0.1 per cent by weight of a polyglycol derivative of sorbitanmonolaurate. Cadmium sulphide yellow was then added and the bottle again rolled. Light yellow polyamide grains which yielded light yellow articles after injection moulding resulted; polyamide grains were mixed with 0.1 per cent of a polyglycol derivative of lauryl alcohol of formula CH3(CH2)11O(CH2CH2O)12H.  The acetate dyestuff Cibacetscharlach (Registered Trade Mark) was then added and rolling of the grains in the container continued.  The resulting grains had the same colour as the original dyestuff with no darkening or dulling of the tint.
