carbon bodies Marin, G. R. (The Carborundum Company) USPat 3 759 353

(18 Sep 19 73) Brake discs, containing keyways or other indentations for bearing circumferential stress on their perimeters, are constructed, using a special technique, with circumferentially-wound carbon fibre reinforcement. The technique involves loosely winding the fibres to a width greater than the axial thickness of the desired (carbon) body, and then axially compressing them to cause radial overlapping of the fibres. With discs having irregular perimeters, the use of such a technique means that the fibres adjacent to the stressbearing perimeter can be made to confirm substantially to the shape of both the perimeter and the indentations.

Steel wire for reinforcing glass and method of production Nagano, K. and Saoyama, Y. (Asahi Glass Co Ltd) US Pat 3 759 754

(18 Sep 1973) Steel wire-reinforced glass, free from bubbles and cracks around the wire reinforcement embedded in the glass, is produced with steel wire heated in a water vapour-containing reducing atmosphere, the dew point of which is at least 20°C before it is embedded in the glass.

US Pat 3 762 881 (2 Oct 1973) This composite high-strength bushing consists of a heavy-load-bearing sleeve of sintered powdered high-performance alloy and a lesser load-bearing support sleeve of sintered base metal such as sintered powdered iron.

Izawa, S. and Toyama, K. (Asahi-Dow Ltd) USPat 3 763 088 (2 Oct 1973) A novel glass fibre reinforced thermoplastic resinous composition is preoared by adding glass fibres to a resinous composition made of 99.5 to 55 weight percent noncrystalline thermoplastic resins, such as styrene type resins, polyphenylene ether resins, aromatic polycarbonate resins, aromatic polysulphone resins, and the like, and 0.5 to 45 weight percent uncured epoxy resins in an amount of 5 to 50 percent by weight based on the total weight of said resinous composition. This glass fibre reinforced thermoplastic resinous composition is suitable for making a large scale shaped article or a shaped article having a complicated structure.

Composite material having cementitious properties

A process is provided for modifying the surface characteristics of a carbonaceous fibrous material (ie either amorphous carbon or graphitic carbon) and to thereby facilitate enhanced adhesion between the carbonaceous fibrous material and a matrix material. Composite articles of enhanced interlaminar shear strength may be formed by incorporating the fibres modified in accordance with the present process in a resinous matrix material.

A composite material, useful as a surgical, medical or orthopaedic wrapping, is provided which will adhere or cohere to another surface, or to itself by the application of moderate pressure either at room temperature or an elevated temperature and will be substantially non-tacky to the touch until the application of such moderate pressure. The composite material comprises a cementitious core having bonded thereto a flexible, open cullular, resilient polymeric protective covering.

The filaments are guided to the form at a rate sufficient to give a clearance between adjacent filaments equal to at least one-half the filament diameter. The amounts of matrix between layers are sufficient to give a similar clearance between successive layers equal to at least one-half the filament diameter,
