Patent GB-798806-A (GB)
Title: Improvements in and relating to polymeric adhesives
IPC: C08F8/00
Filed: 1954-09-13
Abstract: An adhesive composition comprises a reinforced ester of a copolymer containing substantially equimolecular proportions of maleic anhydride and a vinyl ether or styrene or a ring-substituted styrene (e.g. methyl styrene), said copolymer having an intrinsic viscosity of 0.2 to 2 in cyclohexanone, said vinyl ether being a C1 to C8 alkyl vinyl ether wherein the vinyl group may be a -substituted with an inert substituent, at least 65 per cent of the carboxyl groups of the copolymer being esterified with a primary C6 to C16 aliphatic monohydric alcohol, and wherein the ester is of plasticity not greater than 4 mm. and is reinforced by cross-linking or by mixing with a reinforcing agent.  The vinyl ether may be methyl, ethyl, propyl, isopropyl, butyl or isobutyl vinyl ether and specified alcohols are n- or iso-octyl, n-nonyl, n- or branched chain decyl, nundecyl, n-hexyl, lauryl and tridecyl alcohols and a named mixture containing a high proportion of branchedchain decyl alcohol.  The esters may be prepared by heating the alcohol with a dispersion of the copolymer in a diluent, such as xylene, toluene or diethyl benzene, in the presence of a catalyst, e.g. p-toluene sulphonic acid, benzene sulphonic acid or sulphuric acid, and optionally a stabilizer (e.g. 2,5-ditertiarybutylhydroquinone or 2,6-ditertiarybutyl-p-cresol). The ester goes into solution and may be recovered by precipitation with methanol or acetone.  Plasticity of the ester may be further increased (cold flow resistance increased) by (a) the crosslinking, e.g. to a gel content of 10 per cent; (b) addition of the reinforcing agents; or (c) incorporation of a copolymer ester which has previously been cross-linked. Cross-linking may be effected by (i) polyvalent metal oxides such as zinc oxide, titanium dioxide or aluminium hydrate; (ii) initiating a chain-type reaction with a peroxide catalyst such as benzoyl, dichlorobenzoyl or di-t-butyl peroxide; or (iii) di- or tri-hydroxy alcohols such as ethylene and propylene glycols, diethylene and dipropylene glycols and glycerol.  Methods (i) and (ii) may be used together.  The reinforcing agents may be elastomers such as polyvinyl ethyl or isobutyl ether, butadiene/styrene copolymer, polyisobutylene or polyethylacrylate, or may be finely divided materials such as carbon black, silica gel, calcium carbonate or calcium salicylate. The products stick to unprimed film, e.g. ethyl cellulose, cellulose acetate, regenerated cellulose, polyvinyl chloride and polyethylene glycol terephthalic acid, and to cloth or waterproofcloth and are thus suitable as pressure-sensitive adhesives and as surgical dressings.  Coatings on glass or metal may also be provided and laminates such as plywood or glass fibre lamin ates may be obtained. Some of the productsmay be moulded. The copolymers used may be prepared in a monomer solvent such as xylene or benzene using a catalyst such as benzoyl peroxide, and in Example (1) the styrene which contains the catalyst is added dropwise throughout the polymerization.

Abstract: 1,235,176. Coated metal sheet. NIPPON STEEL CORP. and YAWATA ECON STEEL CO. 5 June, 1968 [5 June, 1967; 12 June, 1967; 19 June, 1967], No. 26696/68. Heading B2E. [Also in Division C7] A painted metal sheet is manufactured by subjecting a sheet to an electrophoretic painting with an aqueous paint as an undercoating painting, and then painting the resultant undercoated metal sheet without baking it with a water-soluble or solvent-soluble thermosetting paint and thereafter baking and drying the resultant electro deposited undercoat and final coat at the same time. The metal sheet may be pre-treated e.g. phosphate or chromate treatment before painting. The composition to be electro deposited may comprise a water soluble resin containing an alkyl ester of acrylic acid and/or lower alkyl ester of methacrylic or their ammonium salt or amine salt, and a water-soluble chromium compound added in an amount of 0.05-5.0 weight percent of the resin. The resin may be a copolymer of alkali salt of acrylic acid or amine or ammonium salt of methacrylic acid copolymerised with an acrylic ester. The metals can be iron and steel, hot-dip zinc plated steel, electro-galvanized steel, tin-plate, aluminium plated steel, turn plate. The chromium compounds may comprise water-soluble chromate or bichromate of ammonium, magnesium, strontium, gallium, aluminium. The paint for the final painting may be solventsoluble phenol resins, melamine resins, alkyd resins, acrylic resins, vinyl resins e.g. vinyl chloride resins. The final paint may be applied by a roll coater and the reverse side of the sheet may also be painted. The electrical resistance of the coating formed on the surface of the sheet by chemical pre-treatment is preferably kept below 10 ohms per cm. when effecting the electro deposit. The electricity for the electro depositing painting is supplied through a conductor roll. Melt stuck to the surface of the conductor roll due to the occurrence of arcing between the sheet and the roll is removed by means of a doctor blade immediately after the melt has stuck to the conductor roll while the conductor roll is rotated. The edge part of the conduction roll can also be provided with an electrically insulating material e.g. a rubber or plastics.

Class 135 [Also in Group XXXV] A combined single-acting hydraulic piston and solenoidactuated control valve therefor for operating vehicle windows comprises a cylinder 10, Fig. 1, housing a valve assembly 21 and slidably mounting a piston 20 having a rod 17 operatively connected to the window. The valve assembly comprises a sleeve member 24 closed at its lower end by an inlet fitting 41 supplied by an electricallydriven pump, a spring-urged valve closure member 37 controlling a port 39 through the fitting 41 and a solenoid 32 surrounding the sleeve. The solenoid windings are protected against the water passing through the valve by a rubber sealing ring 28 disposed between washers 25, 26 secured to the sleeve. To raise the window, the pump and the solenoid are simultaneously energised whence the valve 37 is unseated and the piston 20 raised. To lower the windows, the solenoid only is energised and the water beneath the piston passes through the unseated valve 37 and a further valve (not shown), which, when the pump is inoperative, opens to connect the fitting 41 with the reservoir supplying the pump. In a modification, the valve member 37, Fig. 7, is urged upwardly towards closure on to a seating member 33b sealingly connected to the upper end of the sleeve 24. In this case any excess pressure within the cylinder is relieved by downward movement of the valve member against its spring when the solenoid is deenergised. Specification 653,203 is referred to.

Title: Improvements relating to the manufacture of the 1:4-3:6-dianhydrides of mannitol andsorbitol
IPC: C07D493/04
Filed: 1945-10-17
Abstract: 1 : 4 - 3 : 6 - Dianhydrides of mannitol and sorbitol are made by hydrogenating sucrose or invert sugar in an atmosphere of hydrogen at 75-100 atmos. and 110-120 DEG  C. with a Raney nickel catalyst in the presence of sodium and calcium carbonates to give a mixture of mannitol and sorbitol, and treating the mixture with an acid.  The mixture of dianhydrides may be fractionally distilled, and the fractions recrystallized to obtain the separate pure products. Alternatively, mannitol may be separated from the mixture with sorbitol and only the latter converted to the dianhydride.  Suitable acids are hydrochloric, sulphuric, phosphoric, and benzene or p-toluene sulphonic.  In examples: (1) sucrose is added to boiling 0.1 N-sulphuric acid, barium hydroxide added, the filtrate hydrogenated, the product filtered and evaporated to give the hexitols which are refluxed with concentrated hydrochloric acid, the solution evaporated, and the residue distilled under reduced pressure to give the dianhydrides which are then separated; (2) the mixture of hexitols of (1) is heated with concentrated sulphuric acid and xylene so that water is azeotropically removed, and product worked up to recover the anhydrides; (3) xylene and p-toluene sulphonic acid are used similarly to give the anhydrides which are recovered; (4) the mixture of hexitols of (1) is dissolved in aqueous alcohol, manitol removed by crystallization, and the mother liquors treated as in (2) to give dianhydro sorbitol.

IPC: F02C7/047
Filed: 1960-08-05
Abstract: 909,928. Gas turbine engines. ROLLSROYCE Ltd. July 28, 1961 [Aug. 5, 1960], No. 27314/60. Class 110 (3). A gas turbine engine has in combination therewith a water boiler, means for heating the water in the boiler so as to produce steam, and duct means for supplying the steam to engine parts requiring to be heated. The invention is shown applied to a gas turbine propeller engine which may be mounted in a helicopter, the engine also supplying compressed air which is utilized to produce driving fluid for driving the main lifting rotor. The engine comprises low and high pressure compressors 11, combustion equipment 12 and high and low pressure turbines 13, the low pressure compressor and low pressure turbine being mounted on a shaft 14 and driving a propeller 15 through gearing, also through a clutch device 25 as disclosed in Specification 885,272, a compressor 20 which supplies air under pressure through duct 23 to the lifting rotor. A water boiler 26 which may contain 50 to 100 lbs. of water is associated with the engine and comprises two electric immersion heaters 27, 28 which heat the water to produce steam which passes by way of ducts 34, 35 to annular manifolds 32, 33 around the intakes 10, 21 of the compressors 11, 20, all respectively. The steam passes through intake struts 36 and through first stage stator blades 37, thereby serving to prevent icing of the intakes. The steam condenses to water and is ejected into the compressor annular air passages. The heater 27 is permanently in circuit so as to keep the water in the tank warm, while the heater 28 is switched on only when steam is required for anti-icing purposes. The water in the boiler may be kept warm by means of engine exhaust gases passed through a heating coil 31, either in addition to or in place of the electric heater 27. The switch 30 in the circuit 28 may be operated automatically by ice detecting means, or manually.
