Title: New oriented films and tapes of polyethylene-1,2-diphenoxyethane-4,4'-dicarboxylate
Inventor: BUTEUX RICHARD HAROLD BARCLAY
IPC: B29C55/06
Filed: 1966-05-26
Abstract: 1,136,133. Laminates. IMPERIAL CHEMICAL INDUSTRIES Ltd. 24 April, 1967 [26 May, 1966], No. 23578/66. Heading B5N. [Also in Divisions B1, B2, B6, B8, D1, E1, F2 and H1] Polyethylene - 1,2 - diphenoxy - ethane - 4,4<SP>1</SP> - dicarboxylate film and tape having a tensile yield strength in the longitudinal direction of at least 20,000 p.s.i. and moduli in bend of at least 0.8 x 10<SP>6</SP> p.s.i. are produced. The film may be produced by cold drawing a layer of the above film material to at least twice its original length in its longitudinal direction at a temperature which allows the film to draw without formation of voids but with a change of refractive index. The films and tapes may contain additives such as fillers, dyes, pigments, light stabilizers and antistatic agents. They may be laminated to other thermoplastics e.g. polyethylene, polypropylene, polyvinyl acetate, vinyl chloride/vinyl acetate copolymers, ethylene / vinyl acetate copolymers, butadiene/methyl methacrylate Œ styrene copolymers, methyl methacrylate/methacrylic acid copolymers and those of vinylidene chloride with one or more of acrylonitrile, itaoonic acid, acrylic acid or vinyl chloride, or to wood, paper, glass, metals e.g. tin or aluminium or felt, lamination being effected by applying an adhesive e.g. low molecular weight polyesters or copolyesters with or without an isocyanate to the film or tape and then applying a film or tape of other material with heat and pressure. Material may also be applied as a melt coating, from a solution, from an aqueous dispersion or by extrusion through a multi-channel die in which polymer containing additive is fed to one or more channels and polymer without additive to the remaining channels (see Specification 1,096,064). If necessary the surface of the film or the tape may be treated by surface oxidation, flame treatment or by corona discharge to produce stronger adhesion between the base material and the laminating material. The films may also be used as a covering and/or backing for acoustic tiles.

Filed: 1944-12-02
Abstract: 588,627. Combs. RAY, B. M. Dec. 2, 1944, No. 24118. [Class 131] In an ornamental comb the teeth comprise U-shaped resilient members one limb of which is fixed to the comb back and the other is resiliently movable towards and away from the adjacent comb tooth to obtain a spring grip on the hair. The limbs 1, integral with the comb back 2, have a spacing member 5 formed at the roots to prevent the unattached limbs 3 from gripping the hair too tightly. The ends of the unattached limbs 3 are bevelled at 4 to correspond with a bevel formed on the combs back between the integral limbs 1 to prevent lateral movement of the unattached limb to one side of the comb and the comb back 2 may be folded over at 6, or a separate strip added which extends below the ends of the unattached limbs to prevent lateral movement to the other side. In a modification the back of the comb is in two strips movable longitudinally in relation to each other one limb of each tooth being attached to one back strip and the other limb to the other back strip.

Filed: 1929-08-13
Abstract: 317,401. Berlin, D. W., and Brinck, J. A. Aug. 15, 1928, [Convention date]. Peat, preparing.-In a process for the wet carbonization of peat or of other wood substances, the peat or wood substance is made into a sludge with water and is wet carbonized by heat transmitted to it from a liquid heating medium passing through an apparatus in an opposite direction to the sludge. In the example described, the sludge passes through tubes 1, entering at the left-hand end 8 and leaving at the right-hand end 10, the tubes being surrounded by larger tubes 4 through which the liquid heating medium, e.g., water, flows in a direction opposite to that of the sludge. The left-hand or carbonization section of the apparatus and the right-hand or cooling section are connected by a collecting-chamber 5 in which the carbonization is completed. This chamber may be heat insulated and is provided with means 11 for permitting the escape of gases. Some heat is stated to be produced by the carbonizing reactions, additional heat being supplied at a point 6 between the two sections of the apparatus. When entering the carbonizing tube at 9 the heating fluid has the maximum temperature of carbonization, and when leaving it at 8 has substantially the same temperature as the incoming sludge. Means, not shown, may be provided for maintaining the circulation of the sludge and the heating medium. The Specification as open to inspection under Sect. 91 (3) (a) states that the peat sludged in water or other liquid may be passed through the apparatus in the same direction as the flow of the liquid heating medium. This subjectmatter does not appear in the Specification as accepted.
