Patent GB-773231-A (GB)
Title: Improvements in or relating to the production of moistureproof sheet wrapping materials coated with copolymers applied from aqueous dispersions
Inventor: BERRY WILLIAM
IPC: C08J7/048
Filed: 1954-11-25
Abstract: 773,231. Moisture-proof coated films. BRITISH CELLOPHANE, Ltd. Nov. 21, 1955 [Nov. 25, 1954], No. 34231/54. Class 140. A smooth, transparent non-moistureproof surface coating comprising imperfectly coalesced particles of a normally crystalline synthetic organic polymer (said particles being capable of further coalescence by heat treatment) is formed on a flexible base film of water sensitive, organic non-fibrous material, the coated film is dried by evaporation by heat at a temperature too low to promote further rapid coalescence of the polymer particles and then heated at a temperature sufficiently high to fuse the polymer particles into a smooth transparent moistureproof coating. The base film may comprise regenerated cellulose, polyvinyl alcohol, lowly etherified cellulose, lowly esterified cellulose, gelatin, casein and alginic acid derivatives. Specified organic polymers suitable for the surface coating include polyvinylidene chloride and copolymers of vinylidene chloride with acrylonitrile, methacrylonitrile, methyl acrylate, ethyl acrylate, butyl acrylate, isobutylacrylate, methyl methacrylate, ethyl methacrylate, butyl methacrylate, isobutyl methacrylate, vinyl chloride and vinyl acetate. Itaconic, citraconic and mesaconic acids and their anhydrides may be copolymerized with the above to form three component systems. Preferably the vinylidene chloride content of the copolymer should not be less than 80 per cent. The polymer may be applied as an aqueous colloidal dispersion, which should be aged until diffraction rings become clearly discernible in the X-ray pattern of the dispersed polymer. In an example an aqueous dispersion of a vinylidene chloride/acrylonitrile/itaconic acid copolymer prepared by emulsion polymerization and aged for 4 days is applied to both sides of a softened film of regenerated cellulose by the method described in Specification 663,645, the water of the dispersion being wholly absorbed by the base film. The coated film is dried at 95 C. for 15 seconds and finally heated at 160 C. for 3 seconds to coalesce the polymer particles. Specification 655,732 also is referred to.

Abstract: 1391078 Making wood veneer AARONSON BROS Ltd 18 July 1973 [21 July 1972] 34231/72 Heading B5L A method of making wood veneer sheets comprises forming a block by pressing a stack 5 of glued wood veneer laminations between upper and lower jigs 6, 1 having complementary curved profiles of different depths, maintaining the pressure while the glue sets, and slicing sheets from the block using the knife of a flat cutting machine. The depth of the curved profile of the jig of lesser depth, i.e. the concave jig 6, is less than one eight of its width and the depth of the curved profile of the other jig, i.e. the convex jig. 1, is less than one sixth of its width. The central portions, 4b and 9b, Figs. 2 and 3, of the curved profiles of both jigs are of substantially less curvature than the marginal portions 4a, 4c and 9a, 9c of the respective jigs. As described the curved profiles of the jigs are provided by rough sawn surfaces of a number of wooden blocks secured together to form the curved sections 3, 8 of the jigs. Each jig has a width of 20 to 21 inches, the curved profile of the section 3 has a depth of 2# inches and the curved profile of the section 8 has a depth of 2 inches. The depths of the central and marginal portions indicated as 4d, 4e, 4f and 9d, 9e, 9f are respectively, in thirty seconds of an inch, 14, 6, 13, 14, 4, and 13¢.

Title: Improvements in or relating to synthetic resin compositions
IPC: C08L61/04
Filed: 1946-11-19
Abstract: A vinyl halide, such as vinyl chloride, polymer or copolymer containing a major proportion of a vinyl halide and a minor amount of e.g. vinyl acetate, is dissolved in a volatile solvent, a permanently fusible acid-catalysed phenol-aldehyde resin added and this solution is then mixed with a solution of a thermosetting soluble-stage alkali-catalysed phenol-aldehyde resin in a volatile solvent.  The proportion of thermosetting resin is from 2 to 40 per cent of the total resin solids, and the amount of the acid catalysed resin is at least 1/10 of the thermosetting, less than 10 per cent of the total resins and less than the amount of thermosetting resin.  A generic formula for the vinyl resins is given as [CH2=CA.X]n, where A is for the major part hydrogen but may be for a minor part a lower alkyl group, and X is for the major part a halogen but may be for a minor part a monocarboxylic acyloxyl, an alkyl carboxylate, phenyl or a substituted phenyl radical, n being the degree of polymerization. The phenol used in preparing the phenol-aldehyde resins may be phenol, cresol, or alkyl-, aryl-, carboxyl-, hydroxyl- or halogen-substituted phenols, and aldehydes specified are formaldehyde, paraformaldehyde, hexamethylene tetramine and acetaldehyde.  Solvents specified are cyclohexanone, 2-nitroparaffin, mesityl oxide, diisobutyl ketone, methyl n-amyl ketone, used in conjunction with diluents such as xylol, high-flash naphtha or hydrogenated naphtha, and methyl isobutyl ketone along, or with isophorone, or with toluol.  Optional additions are propylene oxide, aluminium powder, yellow lake pigment, and Resin oil Brown Y dye.  The compositions may be applied to metal surfaces and baked to yield stratified coatings.
