Title: Improvements in or relating to adhesives for bonding plasticized polyvinyl halide-containing resins and to articles bonded thereby
Inventor: COMPANY UNITED STATES RUBBER
IPC: C08F291/00
Filed: 1945-05-24
Abstract: An adhesive for bonding bodies of plasticized polyvinyl halide-containing resins comprises 14 to 5 parts of an unplasticized polymer, or copolymer with another monomer, of a vinyl or vinylidene group-containing monomer, dissolved in 86 to 95 parts of a liquid vinyl or vinylidene group-containing monomer or partial polymer free from unpolymerizable constituents other than catalysts, and polymerizable to a resin.  Specified solvents for vinyl acetate polymers and copolymers and partially polymerized styrene are styrene and esters of acrylic acid and its homologues, e.g. methyl methacrylate and for polyvinyl chloride, polymethyl methacrylate and polystyrene, their corresponding liquid monomers.  Preferably, when the dissolved polymer has a molecular weight above 20,000, the solvent should form a polymer having a molecular weight below 20,000 and vice versa.  Catalysts, e.g. hydrogen, benzoyl and lauroyl peroxides and /or ultra-violet light may be used.  In the example 10 parts of an unplasticized copolymer (90 per cent vinyl chloride and 10 per cent vinyl acetate) of molecular weight 16,000 are dissolved in 90 parts of warm methyl methacrylate and 1 part benzoyl peroxide added.  Two sheets of plasticized polyvinyl chloride/acetate copolymer are coated with the solution, superposed and united by heating at 60 DEG  C. under a pressure of 5 pounds per square inch to polymerize the monomer.

Title: Improvements relating to the production of composite materials
Inventor: WINCHCOMBE JOHN JEREMY
IPC: C08G18/10
Filed: 1967-03-21
Abstract: 1,200,662. Composite materials. DUNLOP CO. Ltd. 15 March, 1968 [21 March, 1967], No. 13077/67. Addition to 1,039,861. Headings C3C and C3R. [Also in Division D1] Composite materials are prepared by introducing into an assembly of fibres first a liquid composition which is one part of a polyurethane foam-forming mixture and subsequently a vapour which is the complementary part of the polyurethane foam-forming mixture, and allowing the liquid composition and vapour to react to form a polyurethane foam within the assembly of fibres, the polyurethane foam being hydrophilic. The liquid composition suitably contains a polyurethane prepolymer which is based on at least 10% by weight of polyethylene ether glycol to ensure the hydrophilic nature of the resulting foam. The vapour may comprise an amine catalyst or preferably steam. In examples, the assembly of fibres is in the form of a fibrous web prepared from viscose rayon staple fibres by cross-lapping a carded web of the fibres and a web of crimped nylon monofilaments. The fibrous assemblies may be compressed or moulded during or after foaming. An assembly of fibres may comprise two fibrous webs superimposed one upon the other, and the structure obtained when the polyurethane foam-forming reaction has taken place may then be separated into two layers corresponding to the original two webs, the layers obtained being treated again individually in accordance with the invention. The fibres may also be moulded during foaming between an impervious surface and a porous surface.

Title: The method of manufacturing hydrogen cyanide
IPC: C01C3/02
Filed: 1954-05-05
Abstract: <PICT:0761166/III/1> Hydrocyanic is manufactured by passing a mixture of ammonia and methane or other gaseous hydrocarbon, at 800-980C DEG ., through a bed of fluidized iron-free granular alumina catalyst, which may also contain 0.5-2 mol per cent of an oxide of thorium, titanium, zinc, zirconium, hafnium, silicon, cerium, or calcium.  The gas mixture passes, through tube 3, into silica or porcelain tube 1 at a velocity sufficient to maintain the granular catalyst in a fluidized condition, and product gases are withdrawn at 8.  Tube 1 is surrounded by furnace 9.  The catalyst is prepared by dissolving crystalline aluminium hydroxide in aqueous sodium hydroxide solution and, after diluting, passing steam through. After cooling, the solution is filtered to ensure absence of iron and iron compounds, which have been precipitated as hydroxide. Dilute mineral, e.g. hydrochloric, acid is added dropwise to the pure sodium aluminate solution to pH 6.  Ammonia is then added to pH 8, and the resulting solution filtered.  If a mixed catalyst is required, hydrochloric acid containing a metal salt, e.g. thorium nitrate, is used.  The aluminium hydroxide, or mixed hydroxide gel, is steamed while kneading, dried, and roasted at 300 DEG C. Iron-free water is sprinkled on the roasted cake, which cracks into uniform granules, and the granules are washed with water containing ammonium sulphate until chloride ion-free, and dried at 500 DEG C.

Title: Improved pile or column raising and lowering apparatus
Inventor: NEILSON CHRISTOPHER BERNARD VE
IPC: E02B17/08
Filed: 1958-04-25
Abstract: 851,556. Pile driving and withdrawing. ELECTRO-HYDRAULICS Ltd. July 22, 1959 [April 25, 1958], No. 13278/58. Class 68(2). Apparatus for moving a column relative to a platform comprises a column which passes through apertures in a platform 1 and a sliding structure 4. A rocking member 8 which is pivoted to the platform at 9 has two gripping elements 10 and 11 and is connected to a similar rocking member 12, pivoted at 13, by an hydraulic jack 5. The pivoted member 8 has an arcuate slot 16 therein and the pin 17 which connects the lower end of the jack 5 to the member slides in this slot and is controlled by a secondary jack 20. The upper mounting pin 17 of the jack is similarly controlled by a secondary jack 24. An identical apparatus is shown mounted diametrally opposite that described, but two or more additional gripping devices may be used, equally spaced around the column. To lower the column relative to the platform the following procedure is adopted. Jack 24 is operated to bring the pin 22 to position C, and jack 20 to move pin 17 tp position A. The main jack is slightly extended to rotate member 8 anticlockwise and bring element 10 into engagement with the column and also rotate member 12 clockwise and bring element 15 into engagement with the column. Extension of the jack then produces upward movement of the structure 4; the element 15 sliding along the column. Pin 22 is then moved to position C and pin 17 to position B. Contraction of the jack 5 then results in the element 10 sliding over the column as it moves downwards relative to the platform.

Abstract: 543,316. Automatic control systems. SPEEDRY GRAVURE CORPORATION. Aug. 22, 1940, No. 13352. Convention date, Sept. 6, 1939. [Class 38 (iv)] [Also in Group XL]  Registration.-To indicate or control the registration of a web in a colour printing or other press wherein registration markings 106 are printed by each impression cylinder 100, and in which the marks in laterally displaced series, pass before photo-electric devices each responsive to the registration of a series, a photo-electric cell 114 is illuminated by two intermittent beams of light 111, 115 displaced in phase so that a constant direct current results and the marks pass across one beam so that impulses are produced during the passage which are amplified and applied to control electrodes 29, 31 of a cathode ray tube, whereby the condition of registration is indicated or controlled, other control electrodes 30, 301 of the tube are energized from a potentiometer contact 53 operated in synchronism with the driving mechanism of the machine to cause the electron beam to traverse a straight path with a short dwell in its centre and rapid return from one end to the other. The beam is deflected from this path at a point corresponding to the condition of registration by each impulse and the arrangement may be such as to give two or more impulses while a mark is crossing the light beam. A fluorescent screen discloses the condition of registration and further electrodes may be arranged laterally of the path of the beam and on each side of its central position whereby amplifiers may be energized by the deflected beam to actuate a reversible electric servomotor to operate web-tensioning mechanism to correct the registration. To avoid inaccuracies due to mechanical variation in the printing operation the electron beam is suppressed or its deflection neutralized when in register with a key colour by causing the impulses from a photo-electric cell 114 responsive to key registration marks to apply a voltage to a control electrode (e.g. 27) of the cathode ray tube placed adjacent to the cathode or associated with the deflecting electrodes 31, 31<SP>1</SP>; these impulses may be a multiple of those applied to the electrodes 31, 31<SP>1</SP>.
