Abstracts of patents US PA TENTS
Combination of particulate metal and particulate glass Marzocchi, A. and Leary, D.E. (OwensCorning Fiberglass Corporation) (US Pat 3 992 160 (16 November I9 76) A method is described of making a composite article by coating the exterior surfaces of glass particles with a metal; reducing the size of the coated glass particles to smaller, particulate form; adding glass fibres to them; forming the particles and glass tibre under pressure to a given shape; and sintering the resulting shape to form a permanently-shaped article. High-wear resistant composite seal Fengler, W.H. US Pat 3 992 I64 (16 November 19 76) A composite wear-resisting element for a component of a machine, having a base portion of a metallic material (alumiuium or iron) with a wearresistant coating. The coating consists of an alloy of ruthenium and molybdenum or tungsten in the compositions MosRus and WsRu, respectively. Method and apparatus for fabricating elongate laminated structures Kuehn, R. Jr., (The Boeing Company) US Pat 3 992 240 (16 November 1976) A method of fabricating an elongate, multiple ply laminated structure having a variable cross section.
Process of mixing fillers with polytetrafluorethylene and tetrafluoretbylene copolymers Bensa, R., Monnet, A. and Vincent, G. (Produits Chimiques Ugine Kuhlmann) USPat 992 350(16 November 1976) Polytetrahrorethylene or a tetrafluorethylene copolymer is mixed with a mineral filler. The mixture is crushed or ground such that at the beginning of the crushing or grinding the temperature of the mixture is between -80” and -25°C; after crushing or grinding the temperature of the mixture does not exceed +15”C.

Laminated fiberglass tennis racket Jenks, H.R. US Pat 3 993 308 (23 November 19 76) A tennis racket or similar article made with oriented tibres and resin moulded into an integral structure. Thin rubber surfaced bearings Orndorff, R.L., Jr, (The B.F. Goodrich Company) US Pat 3 993 371(23 November 1976) A journal bearing made from nitrile rubber bonded to a plastics containing mineral filler.
Apparatus for tensioning reinforcement in a concrete pole mould Mori, T. et al (Nippon Concrete Industries Co Ltd) US Pat 3 993 419 (23 November 1976) An apparatus for tensioning reinforcements in the process of manufacturing concrete poles and the like. Cemented carbide material Okawa, T. (Dijet Industrial Co Ltd) US Pat 3 993 446 (23 November 1976) A cemented carbide material consisting of a carbide (tungsten carbide or a mixture of tungsten carbide and a transition metal carbide) and a binder material (based on 20-90% Ni, 1O-80% Co, S-25% Cr), The material has improved resistance to thermal cracking and is useful for plastics hot working.
Emulsified asphalt emulsion fortified with asbestos fibers Bresson, C.R. and Spaulding, F.D. (Phillips Petroleum Company) US Pat 3 993 496 (23 November 1976) A stable anionic asphalt-asbestos emulsion sealant composition comprising an anionic asphalt emulsion and a sufficient amount of suitable asbestos fibres to ensure that when the asphalt-asbestos emulsion is used to impregnate a fabric it will produce a cover structure capable of withstanding fluid or hydraulic pressure. The fibres have been previously treated so that they will not cause asphalt coagulation.
Process for producing a particulate mullite fibril containing composition Jacobson, H.W. and Lewis, CL. (E.I. Du Pont de Nemours and Company) US Pat 3 993 499 (23 November 1976) A process for producing a particulate aluminium silicate composition consisting of a major amount of colloidal, nonspinnable, monocrystalline, mullite fibrils and a minor amount of alumina and silica.
Reinforced styrene acrylonitrile copolymer having improved temperature resistant properties Mclnerney, E.J., Rieber, J.C. and H-Thomas, D.P. (General Electric Company) US Pat 3 993 621 (23 November I9 76) A composition containing a styreneacrylonitrile copolymer, 8-30% reinforced glass flbres, and a brominated flame retarding additive. Polytetrafluoroethylene is present in an amount sufficient to prevent dripp ing of the composition under flaming combustion conditions.
Orthogonally woven reinforcing structure Schultz, F.E. (General Electric Company) US Pat 3 993 817 (23 November 1976) A woven structure, having an internal axis, which consists of threads extending in three different configurations: axial, radial and circumferential.
Resin bonded composite articles and process for fabrication thereof Novak, R.C. and Pike, R.A. (United Technologies Corporation) US Pat 3 993 818 (23 Novertzber 1976) A composite article is described which has preconsolidated plies of continuous, parallel, high strength, high modulus filaments completely surrounded by a fully densified matrix material; the plies are bonded to one another by a layer of adhesive polymer between adjacent plies.
