Title: Improvements in and relating to resinous mixtures
IPC: C08L25/12
Filed: 1957-07-16
Abstract: Resinous mixtures comprise (1) 5 to 55 parts of vinyl chloride-octyl acrylate copolymers, and (2) 45 to 95 parts of styrene-acrylonitrile copolymers.  Preferably (1) contains 60 to 86 parts of vinyl chloride, and (2) 20 to 35 parts of acrylonitrile.  The octyl acrylate may be ethylhexyl, n-octyl, or methyl-heptyl acrylate.  The vinyl chloride-octyl acrylate copolymers may be prepared by polymerizing mixtures of 1.5 to 9 parts of vinyl chloride and 1 part of octyl acrylate at 10 DEG  to 80 DEG  C. until at least 60 and preferably 70 per cent of the manomer mixture is polymerized. Polymerization may be effected (a) in bulk in the presence of catalysts, e.g. azo-diisobutyronitrile, benzoyl peroxide, diacetyl peroxide and lauroyl peroxide, and the product dissolved in acetone and reprecipitated with water or methanol; (b) in aqueous dispersion in the presence of dispersing agents, e.g. hydroxyethyl cellulose, carboxymethyl cellulose, polyvinyl alcohol and styrene-maleic anhydride interpolymers; or (c) in aqueous emulsion in the presence of catalysts, e.g. potassium persulphate, ammonium persulphate, hydrogen peroxide and mixtures of potassium persulphate and sodium bisulphate, emulsifying agents, e.g. sodium dioctyl sulphosuccinate, sodium lauryl sulphosuccinate, sodium tetradecyl sulphate, sodium lauryl sulphate and sodium sulphate derivatives of 7-ethyl-2-methyl undecanol-4, and modifiers, e.g. tertiary dodecyl mercaptan, and the product precipitated by adding an electrolyte, e.g. calcium chloride, or water-miscible organic solvent, e.g. isopropanol. The polymers may be mixed in blenders, mixers and roll mills, preferably by fluxing the stiffer resin and then adding the softer resin to it.  The compositions may contain dyes, pigments, extenders and fillers, e.g. alkaline earth metal carbonates, clays; lubricants, slip agents and processing aids, e.g. stearic acid, palmitic acid, lauric acid and their salts, castor oil, refined petroleum oils, paraffin waxes, microcrystalline waxes and ethylene and isobutylene polymers; stabilizers, e.g. white lead, dibasic lead stearate, dibasic lead phosphite, organo-tin mercaptides, barium and cadmium laurates, trioctyl phosphite, salicylates, epoxidized soya bean oil, barium and cadmium epoxystearates; esters of phosphoric, phthalic, adipic and sebacic esters and polyesters; densifiers and opacifiers.  The compositions may be used in the fabrication of chemical tanks, containers, hoods, ducts, films, rods, tubes and pipes.  Improved chemical resistance may be obtained by applying a surface ply of e.g. a styrene-acrylonitrile copolymer by laminating or surface coating methods.

Patent GB-638580-A (GB)
Title: Improvements in the anti-shrinking treatment of animal fibres
IPC: D06M11/50
Filed: 1947-08-15
Abstract: Textile materials made of or containing wool or other animal fibre are treated with a dilute aqueous solution of a permanganate at a temperature not above 60 DEG  C. and a pH between 5 and 10, this treatment being preceded or followed by treatment with a solution containing 0.5-10 per cent by weight of a sulphur-containing reducing agent at a pH between 5 and 10.5.  The tendency of the materials to shrink when washed is thus reduced.  The permanganate may be an alkali or alkaline-earth permanganate and the reducing agent may be a sulphite, bisulphite, metabisulphite or hydrosulphite of an alkali metal, calcium, magnesium or ammonium. The permanganate solution may be buffered by addition of zinc sulphate.  The materials treated may be loose wool, slubbing, yarn, fabrics or garments, in the oil or scoured state, and the animal fibre may be mixed with cellulosic fibres such as cotton or rayon, or rubberised threads.  The treatment may be applied before or after dyeing.  In an example, wool yarn is treated at atmospheric temperature with a dilute solution of potassium permanganate containing zinc sulphate and a wetting agent, e.g. a sulphonated fatty alcohol or an ethylene-oxide condensation product, and the material is then drained and treated with a 2 per cent solution of sodium bisulphite at 40 DEG  C.  Specification 569,730 is referred to.

Abstract: 654,373. Magnetic induction accelerators. BRITISH THOMSON-HOUSTON CO., Ltd. Aug. 15, 1947, No. 22761. Convention date, Aug. 17, 1946. [Class 39 (i)] [Also in Group XL (b)] In a synchrotron or betatron-synchrotron particle accelerator in which electrons or positive ions accelerated to a velocity close to that of light have their energy further increased by means of an electric field produced across the gap of a resonant transmission line, the line conductors include in the space between them a region inside the envelope so that the dielectric constant between the conductors is determined principally or wholly by the medium within the envelope. The resonant transmission line may comprise concentric cylinders located inside, Fig. 11, or outside, Fig. 12, the envelope proper. In Fig. 11, the cylinders comprise coatings 102, 103 on recessed and re-entrant portions of the envelope wall. In Fig. 12, the cylinders 121, 122 may comprise metallic coatings on insulating formers. In another embodiment, Fig. 9, the resonant transmission line comprises a hollow cylindrical conductor 81 inside the envelope 82, and a pair of parallel strip conductors 86, 87 outside the envelope. The conductor 81 may comprise a metallic coating on an insulating former. The Specification also comprises a resonant transmission line in which the conductors are coatings on the inner and outer surfaces of the envelope wall, the envelope wall entirely filling the space between the conductors. A portion of the outer coating is removed to leave a longitudinally-extending strip relatively isolated from the remainder of the coating. The length of the strip is chosen to match the resonator to the energy input transmission line which is connected between the strip and the remainder of the coating. Another portion of the outer conductor may be removed to provide a window whose opening may be adjusted by means of a slidable shutter for tuning purposes. Specifications 585,992 and 622,148 are referred to. The Specification as open to inspection under Sect. 91 comprises also a resonant transmission line in which the inner conductor 144, Fig. 13 (Cancelled), is a coating on the inner wall of the envelope and the outer conductor 145 is shaped to enclose a large part of the space between the magnetic polepieces 140, 141. This subjectmatter does not appear in the Specification as accepted.

Abstract: 1,057,395. Converting. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. June 7, 1963 [June 12, 1962], No. 22764/63. Heading H2F. [Also in Division H3] In a pulse generator of the type in which an artificial line K is charged through a saturable inductor L 1  and discharged through a load under control of saturable inductors L 2 , L 3 , spurious reflections in the line K at the end of each pulse are minimized by a rectifier G and resistor R equal in value to the characteristic impedance of line K. As described, 3 microsecond positive pulses at terminal A 1  saturate inductor L 1  so that capacitor C discharges into the line K: A current now builds up in inductor L 2  until that inductor becomes saturated when the line K discharges through the magnetron load M coupled via transformer T. The pulse is terminated when the inductor L 3  saturates, short-circuiting the primary of transformer T. Further surges in line K are minimized by the action of rectifier G and resistor R. The reaction time of inductor L 2  plus the transit time of the right-hand portion of the line K should be equal to or greater than twice the difference between the transit time of the line and the reaction time of inductor L 3 . The reaction times of the saturable inductors may be adjusted by variation of a bias current in an auxiliary winding.

Abstract: 484,564. Raising liquids by compressed air. EWART, J. W. Aug. 12, 1937, No. 22944/36. [Classes 8 (i) and 102 (ii)] An hydraulic power apparatus using energy obtained from the natural heads of rivers and the like comprises an open-bottomed chamber in which air is compressed by the rise of water artificially produced by a lock or dam, the air being used to force liquid, other than the river water, in a step-by-step manner from one to another of a series of connected superposed compartments, the liquid from the uppermost compartment driving an hydraulic engine at a lower level and then returning to the lowermost compartment, so that the same liquid is repeatedly circulated. Preferably, the suction produced in the air-chamber when the water is released from the dam is also utilized for raising the liquid from one compartment to another. In the apparatus shown, a conduit 1c delivers water from a river taken from a point higher up its course to a tank 1a containing an open-bottomed airchamber 1 connected by a pipe 4 to the upper ends of superposed tanks 5 .... 10. The air pressure produced by the rise of water in the chamber 1 is applied to the fluid in the alternate tanks 5, 7, 9 by opening the valves 5d, 7d, 9d, the fluid being thereby forced through the connecting pipes 5a, 7a, 9a, into the tanks 6, 8, 10, the air vents 6c ,8c, 10c of which are opened. When the tank 1a is full it is emptied through an opening 1b, the discharge from the conduit 1c being byepassed into the river, during which time the suction effect produced in the chamber 1 may be caused to raise liquid into certain alternate tanks which have been emptied by the previous air pressure, so that the system operates continuously. The liquid flows from the tank 10 through an hydraulic motor 12 to a reservoir 11 whence it is supplied to the lowermost tank 5 for re-circulation. The valves controlling the operation of the system are automatically operated. Part of the air compressed during the rise of water in the tank 1a may be used to drive machinery, the remainder being used to raise water.
