Apparatus for producing rigid foam plastic laminated board
fibrous sheet of high wet strength. The latter consists of mixtures of inorganic, polymeric and cellulosic fibres, and is bonded to the laminate with a latex or epoxy type adhesive.
Polyester composition (ICI Ltd)Br Pat 1 512 516 (1 June 1978) The problems of moisture reducing the viscosity of mineral (glass, talc, mica) fdled thermoplastic polyesters at the moulding temperature is overcome by incorporating eg calcium oxide. Orthopeadic material (Mitsubishi Petrochemical Co Ltd) Br Pat 1 512 553 (1 June 1978) A photocurable acrylic/isocyanate copolymer is used to impregnate paper or glass tape which can then be used as a hardenable bandage in orthopaedic applications. Formable plastics-metal laminates (BASF Aktiengesellschaft) Br Pat 1 512 735 (1 June 1978) A laminate consisting of a metal foil (eg AI) adhered to a fibre-reinforced thermoplastic such as polyolefm or polyamide is prepared by heating eg glass mats and pressing into them extruded thermoplastic. The product will withstand high supporting loads.
Fiber-reinforced plastic unitized boat hull frame Richard V. Humphrey (10 Loving Ave, Kingston, Mass. 02364) USPat 4 041 561 (16 August 1977) The frp boat hull frame comprises a longitudinal frp frame member and several transverse frp frame members. Apparatus and method for dispening and reinforcing cementitious material I.L. Johnson, 7100 Down Road, Edina, Minn 55435 US Pat 4 042 175 (16 August 1977) The cement is reinforced with glass fibres. These are introduced into the apparatus in the form of rovings which are then dissevered to give individual fibres of substantial length. In the f'mal product the fibres are randomly distributed throughout the cementitious material.
blade made from the composite material and which is intended for use in a fluid flow machine. Apparatus for producing rigid foam plastic laminated board Jones, W.R. (The Celotex Corporation) US Pat 4 043 719 (23 August 1977) The laminated board produced by the apparatus consists of a foam plastics core encased between two members.
Metal-refractory composite material Bibring, H. et al (Office National d'Etudes et de Recherches Aerospatiale) US Pat 4 043 841 (23 August 1977) _ The material is for use in the manufacture of aviation turbine blades and consists of a nickel-based superalloy matrix and a reinforcing phase of oriented monocrystalline niobium carbide fibres formed in situ during the production of the material by unidirectional solidification.
Method of fabricating composite Superconductors Chigasakishi, Y.K. (Showa Electric Wire and Cable Company) US Pat 4 043 028 (23August 1977) Method of making plastic ski The superconductor comprises a thermal Howe, G.H. and Schmidt, W.L. (AMF and electrical matrix embedded in stock Incorporated) US Pat 4 044 083 (23 product which consists of a tin-based August 1977) alloy core surrounded by a copper The ski comprises an aluminium and jacket clad with a niobium tube. The plastic foam sandwich structure and is composite structure is then comade from two preformed subassemblies reduced to the desired size and fmally between which a foamable thermosetting heat treated. resin is poured.

Nonwoven thermoplastic fabric Brock, R.J. and Meitner, G.H. (Kimberly-Clark Corporation) US Pat 4 041 203 (9 August 1977) A nonwoven fabric-like material comprises a web of continuous and randomly deposited, molecularlyoriented filaments of a thermoplastic polymer and an integrated mat of discontinuous, thermoplastic polymeric microfibres. Transparent, impact-resistant polyesterurethane laminates Seeger, N.V. and Kaman, A.J. (PPG Industries Inc) US Pat 4 041 208 (9 August 1977) An optically-clear, energy-absorbing laminate comprises a glass sheet bonded to a sheet of an unreacted isocyanatefree, thermoplastic, transparent polyesterurethane.

Non-destructive testing of bonding laminates Ingle, H.R. US Pat 4 043 197(23 August 1977) The apparatus is used to test laminates which include a substrate and a face sheet bonded to it. A specially adapted vacuum chamber is drawn across the face sheet and any displacement of the sheet into the chamber is detected. Impact resistant composite article comprising laminated layers of collimated filaments in a matrix wherein layer-layer bond strength is greater than collimated f'damentmatrix bond strength Carlson, R.G. (General Electric Company) US Pat 4 043 703 (23 August 1977) The laminates comprise collimated fdaments sandwiched between two metallic foil layers. Also described is a
Process for reinforcing non-wovens Reinach, A.H. et al (Ciba-Geigy Corporation) US Pat 4 044 178 (23 August 1977) The non-woven fibre material is impregnated with an aqueous preparation containing a binding agent and a foaming assistant. Film laminates having a reirradiated layer Kremkau, W.P. (W.R. Grace and Co) US Pat 4 044 187(23August 1977) The properties of polymeric f'tlm laminates are improved by irradiating a laminate which has been prepared from both cross-linked and uncrosslinked layers, the cross-linking having been achieved by irradiation.
