Automobile polyester body filler
Heat vuicanizable polysiloxane compositions containing asbestos (General Electric Company) UKPat I 336 978 (14 Nov 1973] Silicone elastomers with improved strength result from vulcanizing a composition consisting of 15 to 94.75 % polysiloxane, 5 to 75 % asbestos fibre, and 0.25 to 10 % of an acrylic ester such as methylacrylate.
Method of manufacturing objects of reinforced plastics materials (Allmanna Svenska Elektriska Aktiebolaget) UK Pat 1 337131 (14 Nov 1973) A reinforcing material is impregnated with a composition consisting of an unsaturated polyester, a monomer, a polyisocyanate, an accelerator such as cobalt naphthenate and a metal chelate such as titanium acetoacetonate. In use each layer of prepreg is coated with a catalyst such as cyclohexanone peroxide. Under pressure the laminate cures without heating.
Process for the manufacture of carbon fibres (Stamicarbon NV) UK Pat I 337367 (14 Nov 1973) Incorporating an immiscible polymer in tarry materials strengthens fibres spun from them and prevents breakage during subsequent handling and carbonization.
Improvements in building materials (Synthetic Fabrics (Scotland) Ltd) UK Pat 1 337 438 (14 Nov 19 73) Load bearing building materials with high compressive strength consist of polypropylene or polypropylene copolymer filled with a hard aggregate material and essentially free of voids.
Process for preparing novel glass fibre reinforced thermoplastic compsoition (Mitsubishi Petrochemical Co Ltd) UKPat 1 338 126 (21 Nov 1973) Reinforced polypropylene with acceptable mechanical properties, heat resistance and colour are prepared by using an organosilane treated glass fibre and adding 0.04 to 0.5 % organoperoxide and 0.1 to 0.3 % silane coupling agent to the polymer. Laminated films (Sumitomo Chemical Company Limited) UK Pat I 338 669 {28 Nov 1973) A composite wrapping material with

high strength, clarity and interlaminar bond strength comprises a film of a polyolefin bonded to a film of an acrylic polymer containing f to 50 % of a copolymer obtained by grafting vinyl chloride to an ethylene-vinyl acetate copolymer.
Reinforced polystyrene laminate (Lavorazione Materie Plastiche S.p.a.) UK Pat i 338 821 (28 Nov 1973) A reinforced polystyrene foam laminate with more consistant strength properties results from bonding a closed cell foam layer on each side of a sheet of kraft paper.
Laminated paper with reinforcing fibres (Hudson Pulp and Paper Corporation) UKPat 1 338 836 (28 Nov 1973) A high impact-resistant packaging material is made by bonding together two sheets of extensible uncreped paper, which has been compressibly shrunk, using an extensible hot melt adhesive containing a polyester fibre web.
Improvements relating to fibre reinforced structures (British Aircraft Corporation Ltd) UK Pat 1 338 902 (28 Nov 1973) A method of using a weak, low density material as a former in a filament winding operation involves first bonding a layer of glass reinforced resin on its surface. The material is stiffened sufficiently to be used as a former without damage.

Method of making bubble-free fibre reinforced plastic laminates by tamping operations Reinke, F. US Pat 3 746 589 (17Jul 1973] Method and apparatus for making articles, such as building components, by tamping a layer of liquid plastic material. The tamping is performed by directing blows on the layers in adjacent areas arranged like a grid, whilst the layers are moved relative to the areas.
Foamed plastic laminate and method of making same Reynolds, A.J. US Pat 3 746 604 (17Ju11973] A technique is outlined for overcoming the delamination problems encoun
tered during the use of laminated structures having a foamed plastic core. The natural adhesiveness existing between outer panel members and the foamed plastic inner core is enhanced by adhesively affLxing a thin, continuous, convoluted ribbon of plastic to the interi6r surfaces of the outer panel members. The ribbon is affLxed prior to the foaming reaction which produces the foamed inner core, with the result that the core materials bonds to the ribbon of plastic and the interior surfaces of the panel members, to form an interlocking unitary structure.
Reinforced rubber composition Dunnon, D. D., Wagner, M. P. and Derringer, G. C. (PPG Industries Inc) US Pat 3 746 669 (17 Ju11973) The invention comprises reinforced rubber compositions, which include rubber, discontinuous fibre filaments, a finely-divided reinforcing siliceous pigment and a resin formed by the reaction of a phenol with a methylene donor.
Automobile polyester body filler McGuire, H. P. US Pat 3 746 670 (17Ju11973) A composition comprising a liquid component including a polyester resin and an accelerator and a dry filler component. The latter consists essentially of a uniform mixture of asbestos fibres, metallic powder and soybean meal, the soybean meal functioning as an adhesive agent to bond the components together: this enhances the workability, while minimizing dusting of the compound during working.
Method of making composites Alexander, J. A. (TRW Inc) US Pat 3 748 721 (31 Jul 1973) Components such as airfoils for jet engines and other complex shaped parts, are provided by fibre-reinforced high strength, lightweight metal matrix composites economically prepared to close dimensional tolerances by applying matrix tapes in side-byside relation to a contoured metal base sheet or foil. A body of the desired thickness and shape is built up with superimposed layers of such applied tapes, which are then covered with a contoured metal cc.ver sheet or foil.
