Title: Process for the production of polymeric materials
IPC: C08F291/18
Filed: 1959-04-16
Abstract: Segmented polymers, i.e. graft and block copolymers and branched chain homopolymers are produced by a process in which a normally solid high polymer having molecules containing peroxy groups is irradiated with ultra-violet light in the presence of a monomeric compound containing one or more olefinic double bonds and capable of polymerization under the influence of free radicals, the irradiation being carried out in the absence of a concentration of oxygen which would otherwise inhibit the polymerization of the monomeric compound. Preformed polymers specified are polythene, polypropylene, polyisobutylene, polystyrene, polyvinyl alcohol, polyvinyl acetate, polyvinyl formal and butyral, polyvinyl and polyvinylidene chlorides, polytrifluorochloroethylene, polytetrafluoroethylene, polymethyl and polybutyl methacrylates, polyacrylonitrile, polyvinyl pyridines, poly N-vinyl pyrrolidone, polybutadiene, polyisoprene, polychloroprene interpolymers of butadiene with styrene, acrylonitrile or methyl methacrylate, epoxide polymers, polyethylene glycols, polyesters, polyamides, polyurethanes, polyureas, polysulphonamides, rubber, chlorinated rubber, rubber hydrochloride, gutta percha, balata, cellulose and its esters, ethers and acetals, cotton, wool, silk, starch, copal resins, shellac and alginates. Monomeric compounds specified are acrylic and methacrylic acids and their methyl, ethyl, n-butyl and allyl esters, 2-ethoxyethyl and 2-chloroethyl methacrylates, ethylene dimethacrylate, acrylonitrile, methacrylonitrile, acrylamide, n-butyl acrylamide, vinyl and vinylidene chlorides, methyl vinyl and methyl isopropenyl ketones, styrene, vinyl toluenes, vinyl toluene sulphonic acids, divinyl benzene, acenaphthalene, vinyl acetate, vinyl pyridines, vinyl carbazole, N-vinyl pyrrolidone, butadiene, isoprene and chloroprene. Peroxy groups may be introduced into the performed polymer in the following ways: (a) by subjecting the polymer to ionising radiation or ultraviolet light in the presence of oxygen or air, (b) by treating with molecular oxygen a copolymer containing units of isopropyl- or isooctyl-styrene, (c) by saponifying a copolymer containing isopropenyl acetate units and treating the polymer product with hydrogen peroxide, (d) by masticating the polymer in an oxygen-containing atmosphere at a temperature below 170 DEG C. (e) by treating the polymers with sulphochromic acid, mixtures of sulphuric acid and potassium permanganate, aqua regia, Caro's acid or ozone and (f) in the case of polythene by heating the polymer in an atmosphere of oxygen. In the examples polythene is peroxidised by mastication in the presence of oxygen, contacted with styrene, acrylonitrile or methyl methacrylate, degassed and then irradiated with ultra-violet light. Specification 857,797 is referred to.

Patent ES-310152-A1 (ES)
Title: Process for the preparation of ethers
IPC: C07C41/09
Filed: 1965-03-05
Abstract: An ether is prepared by dehydrating the corresponding acyclic alcohol in the liquid phase, at 90-170 DEG C. and at a pressure sufficient to maintain the reaction mixture in the liquid state, in the presence of a cation-exchange resin derived from styrene or divinyl benzene and bearing strong inorganic acid radicals of which the "equivalent pH" is at most 2, the contact time of the alcohol with the catalyst being from 10 minutes to 10 hours. The "equivalent pH" is the pH of 100 ml. 0.1 N aqueous NaCl brought into contact with 10 milliequivalents of the resin. The resin is preferably of the polystyrene sulphonic type in its "hydrogen" form. The reaction may be carried out batchwise, by agitating the alcohol with the resin, or continuously, by passing the alcohol through a bed of the resin. The starting material may be a mixture of alcohols and may contain water and/or the corresponding ether. Examples describe the dehydration of butyl and ethyl alcohols.
Patent ES-331694-A1 (ES)
Title: Improvements in or relating to Methods Of Fixing A Powder To A Support
IPC: H01J9/227
Filed: 1966-09-28
Abstract: A method of fixing a powder to a support comprises, taken in order, the steps of spreading a solution of a photo-sensitive binder on the support, drying the resulting layer and exposing selected areas of the layer to radiation so that selected areas of the layer are more soluble in a solvent than other areas, removing the soluble areas of the layer with the solvent, spreading over the support and binding layer a suspension of the powder which does not contain a macromolecular organic compound, adding to the spread suspension a solution of a macromolecular organic compound, e.g. polyvinylalcohol, drying the suspension and solution and rinsing away the powder from areas of the support no longer coated with binder. The radiation may harden the exposed areas of the binder to render them insoluble in the solvent. The method may be used to apply the guard bands to the recess of an indexing type colour television tube. A specific example with quantities is given in which black iron oxide is fixed to a colour index tube screen using a binder comprising polyvinylalcohol with an ammonium bichromate sensitizer, and a solution of polyvinylalcohol as the macromolecular organic compound.

Patent ES-345428-A1 (ES)
Title: Tracing apparatus
IPC: G06K11/02
Filed: 1967-09-25
Abstract: A photo-electric line, or boundary, follower is moved along a line by a co-ordinate drive system in response to signals emitted by two photo-cells positioned one after the other to view different portions of the line and each traversely scanning the line repeatedly. For following a line the photocells are mounted in a rotatable head with one photo-cell positioned upon the centre of rotation and the other ahead of it and known as the steering photo-cell. If the transverse scans become misaligned with the line the steering photo-cell generates a signal out of phase with a reference signal which rotates the head to turn the scan relative to the line and also to rotate the rotar of a synchorous resolver. One winding of the rotor is fed with the signal from the other photo-cell and a second winding with reference A.C. Control voltages are taken from 90 degrees phased stator windings to X and X motors of the co-ordinate drive system, whereupon the head is driven back in the direction of the line and on reaching it realigns itself. If a boundary between light and dark regions is being followed a pair of photo-cells replace each of the previous ones each pair being arranged side by side and their outputs fed to a differential amplifier. To scan the line each photo-cell or each pair may be mounted upon an oscillating rod as described in Specification 1,104, 578 or an image of the line may be scanned optically across the photocells.

Abstract: An anisotropic permanent magnet is manufactured by orienting particles of an anisotropic mass of powder of a ferromagnetic element or alloy or of ferrite, by subjecting the mass to external magnetic field, isostatically compressing the mass, and slightly deforming it anisotropically and plastically while maintaining isostatic pressure. An alloy powder has hexagonal crystal structure and composition M 5 R wherein M is Co, or a combination of Co with one or more of Fe, Ni, Cu, and R is one or more of elements yttrium, thorium, and rare earths. Alternatively M is Co and R is Sm. The powder is placed in a rubber bag and oriented in a field of at least 1000 Oe., and compressed under magnetization with pressure of 1-2 kilobars, after which the bag is evacuated and sealed for isostatic densification at, e.g., 8k bars. The bag is removed and the block soldered into a ductile, e.g. lead container, which is hydrostatically and isostatically compressed to, e.g. 20k bars, and deformed anisotropically and plastically, during which a saturating field of, e.g., 30,000 Oe. is applied. The container 10 is placed between two perforated loose dies 8, 9 resting on shoulders 2 of the bore of an hydraulic compression vessel 1 containing petrol, and opposed plungers 4, 6 are operated by rams 5, 7. Pressure on container 10 is exerted by plungers 4, 6 until on raising pressure on plunger 6 the liquid column and both plungers descend, until plunger 6 deforms container 10 between dies 8, 9. Pressure is then released and the container removed and opened.
