Title: Improvements in or relating to cross-linked polymer compositions
IPC: C08F236/04
Filed: 1958-11-21
Abstract: Cross-linked polymers are prepared by reacting linear synthetic polymers of polymerizable ethylenically unsaturated monomers, which polymers contain carboxyl or sulphonic acid groups and at least one of the monomers being an a , b -olefinically unsaturated acid and the polymer containing at least 0,005 chemical equivalents by weight of organic acid hydrogen for each 100 parts by weight of polymer and having a molecular weight of at least 500, with monocarbodiimides. Preferred carbodiimides are N, N1-diisopropyl-, N, N1-diisobutyl-, N, N1-diisoamyl-, N, N1-dicyclohexyl-, N, N1-diphenyl-, N-phenyl-N1-p-chlorophenyl-, and N-isopropyl-N1-p-dimethylaminophenyl carbodiimides.  The rate of reaction may be controlled by adding ammonia and amines. The polymers may be prepared by polymerization in bulk, solution or emulsion in the presence of emulsifiers e.g. sodium naphthalene sulphonate-formaldehyde condensates and sodium alkylaryl sulphonates, buffers, catalysts, e.g. organic peroxides and hydroperoxides, azodinitriles and persulphatesulphite redox systems, and modifiers, e.g. mercaptans, sulphides, disulphides, bromotrichloromethane, di-bromodichloromethane, cumene and xylene. Many suitable monomers are listed and examples describe the reaction of N, N1-dicyclohexyl carbodiimide with (I, II, III, VIII and XV) butadiene-acrylonitrile-methacrylic acid copolymers; (IV and XI) butadiene-methacrylic acid copolymers; (V and X) butyl acrylatemethacrylic acid-acrylic acid copolymers; (V) maleic acid-butyl acrylate copolymers; (IX) butadiene-styrene-methacrylic acid copolymers with (VII and XVIII) carbon black; (XIII and XIV) chloroprene-methacrylic acid copolymers; (XVI) butadiene-acrylonitrile-ethylene sulphonic acid copolymers and (XVIII) poly-a -sulphonyl acrylic acid; N, N1-diphenyl carbodiimide with (I) butadiene-acrylonitrile-methacrylic acid copolymer; N, N1-diisopropyl carbodiimide with (VI) butadiene-acrylonitrile-methacrylic acid copolymer with (XIX) carbon black; and N, N1-didodecyl carbodiimide with (XII) butyl acrylate-methacrylic acid-acrylic acid copolymer.  The products may be used for coating, e.g. glass and aluminium, inpregnating leather, as caulking compounds and putties, binders for solid fuels, and binders for non-woven articles of cotton, wool, asbestos and synthetic fibres.

Title: Improvements in or relating to protecting metal surfaces by corrosion inhibiting atmospheres
Inventor: SINDERY GUY GROSVENOR
IPC: C23F11/02
Filed: 1958-11-21
Abstract: 873,776. Protecting metal surfaces by corrosion inhibiting atmospheres. HOUSEMAN & THOMPSON Ltd. Feb. 22, 1960 [Nov. 21, 1958], No. 37638/58. Class 94(1). A method of protecting metal surfaces comprises passing over or through a vapour phase inhibitor a current of gas at a temperature sufficient to vaporise the inhibitor, bringing the resulting gaseous mixture into contact with the metal, and then sealing off the metal and the gaseous mixture from the outer atmosphere, for example by enclosing the metal in an envelope or other container that can be sealed. The inhibitor may be cyclohexylamine carbonate, or dicyclohexylamine nitrite, or a mixture of the two. The gas may be air or nitrogen and the metal is preferably initially dried by circulating over it a drying gaseous medium. The invention has particular application to preserving the internal surfaces of boilers and pipes when these are not in use.

Abstract: 1399624 Plastics-surfaced decorative laminates FORMICA INTERNATIONAL Ltd 31 July 1973 [15 Aug 1972] 37974/72 Heading B5N Deterioration-resistant decorative laminates of lustrous metallic appearance are obtained by heating and pressing on assembly of (i) a core of one or more phenol-formaldehyde resinimpregnated kraft paper sheets, (ii) an adhesive layer, and (iii) a surface layer of transparent, heat-set, biaxially-oriented polyethylene terephthalate having on at least part of its inner surface a metal coating. The metal coating may be Cu, Ag, Au, Ni, Cr or, preferably, vacuumdeposited Al, may be overall or discontinuous, and may be opaque and reflective or translucent. If the coating is discontinuous, the core may be overlaid with a decorative paper impregnated with melamine- (preferred), urea- or benzoguanimine-formaldehyde resin or polyester resin. The adhesive may be a polyurethane or linear polyester composition and may be present as a coating on the metallized layer, decorative paper or uppermost core sheet, as an impregnant in a paper layer, or as a selfsupporting sheet or foil; alternatively the impregnant of the aforesaid decorative paper may constitute the adhesive. Decorative effects may be enhanced by colouring and/or printing the constituent sheets, adhesives and resins. Discontinuous metal coatings are preferably obtained by printing a continuous coating with etch-resistant ink and etching the remainder; the ink may remain to give a decorative effect through "undercutting". The assembly may be compressed using plates and/or release sheets which are so formed as to impart a desired surface texture, e.g. gloss, suede or embossed.

Wire reeling apparatus includes a rotating laying tube through which wire is fed to be laid in a worm thread which rotates with the laying tube. A laying tube 63, carried by a rotating frame 64, directs wire W into the thread of a worm 65 secured to the frame 64 and enclosed by a casing 66. The pitch of part of the wall of the worm thread is adjustable. In another embodiment, Figs. 3, 4 (not shown), the laying tube directs the wire into another part of the worm thread; theo utlet end of the laying tube is adjustable in inclination. The pitch of the worm may decrease in the conveying direction. The worm thread may be multistart. The turns of wire issuing from the worm thread may be carried away by three endless conveyer belts, 85, Fig. 5, or by a plurality of worms, Fig. 6 (not shown), spaced around the periphery of the wire turns. The wire turns are checked and tripped by an abutment 89 to fall into a collecting vessel 86. The apparatus may be vertically instead of horizontally arranged. In a further arrangement, Fig. 7, turns are carried by inner endless conveyers 107, 108 co-operating with an outer conveyer 105 and are turned over by passage up a guide 109 to fall into a collector 106. In another arrangement, Fig. 8, the turns are tripped by a member 119 as they issue from the worm thread 114 to fall on to a conveyer 115 thence to pass to a collector 116. A simple shoot or cam wheel or chain may replace the member 119. Alternatively the turns may be allowed to fall directly on to a slowly moving conveyer.

A modification of the parent Specification in which means are provided to prevent the inertia of the feeler member and other parts carrying them beyond the appropriate position when actuated by a record of intermediate size. A stop-member 1 is mounted on a vertical shaft 2 passing through the baseboard 4 and biased to the upper position by a light spring 36. A flag-type feeler arm 5 mounted at the upper end of the shaft is struck by a record of intermediate size descending to the turntable 10 and rotates the shaft against the action of the spring 33 until the edge 34 strikes the stop-pin 34. In this position the flange 13 engages the shoulder 11 of the teasing lever 8 which controls the radius at which the pick-up is set down. Records of large diameter striking the lever 5 cause both axial and rotational movement of the shaft and move the edge 35 below the stop-pin 34 so that the flange 13 can rotate to a position where it engages the shoulder 12 of the lever 8. Resetting of the device is achieved by an element 14 actuated by the cycling mechanism. Specification 792,961 also is referred to.
