Laminating compositions and uses Glass fiber-reinforced thermoplastic polycarbonate molding compositions with improved tough-elastic properties Adelmann, S., Margotte, D. and Merten, J. (Bayer Aktiengesellschaft) US Pat 4 048 133 (13 September 1977) Polycarbonate moulding compositions based on high molecular thermoplastic aromatic polycarbonates (containing 10-30% by weight of glass fibres) and containing 1-5% by weight of poly(256-dlalkyl-1, 4-phnylene oxide) are described.
Reinforced elastomeric articles Moring, P.L.E. and Raines, W.J. (Dunlop Limited) US Pat 4 048 362 (13 September 1977) A method of bonding an aromatic polyamide, which if manufactured as a fibre would be termed an aramid, to a nitrile rubber composition is described. A coating of vinyl chloride polymer is applied to the aromatic polyamide, and then the rubber in contact with the surface is vulcanised.
Unmuth, G.E. (Petrolite Corporation) US Pat 4 048 376 (13 September 1977) Two plies are laminated together using a composition comprising 20-40% of atactic polypropylene, 10-25% of a petroleum polymer resin, with the balance made up of microcrystalline wax. The composition is applied to one or both plies at a temperature about 110°C and then the plies are allowed to cool. The resulting laminate has good laminating strength at high temperatures.
Adhesive laminated packaging materials Pelzek, V.J. (Browne Pacaging Inc) US Pat 4 048 3 78 (13 September 1977) A flexible, laminated, heat-sealable packaging material comprises an outer film of biaxially oriented polypropylene terphthalate, and an inner film of a heat-sealable, polymeric material bonded to one side of the outer fdm by an intervening adhesive layer consisting of 70-90% of an ethylenevinyl acetate copolymer.

Steit, K.F. (Phone-Ducs Inc) US Pat 4 050 721 (27 September 19 77) The plastics pipe is reinforced with reinforcing flanges and ribs.
Reinforcing material for concrete Lundgren, B.G.S. (SKF Nova) US Pat 4 050 949 (27September 1977) The reinforcing material comprises short, straight reinforcing steel flakes which are uniformly and randomly distributed in the concrete.
Controlled density fill material containing fly ash High-wear-resistant composite machine
laminates Hoover, W.H. US Pat 4 048 365 (13 September 1977) The armour structure comprises monolithic plates connected together but spaced apart. Each plate consists of mats of glass fibres in a cured thermosetting resin and is about 3 mm thick. The plates are bonded together by a fibrous material impregnated with a rigid binder.
element Fengler, W.H. US Pat 4 048 382 (13 September 1977} A composite wear-resisting element is described for a running seal of a machine, comprising a base of a metallic material (aluminium or iron) and subject to excessive wear during operation of the machine, and a nonporous exposed wear-resistant coating overlying the base and fused to it. The coating consists of an alloy of molybdenum.

Lane, M.K. and Anderwon, W.C. (United States Gypsum Company) US Pat 4 049 866 (20 September 19 77) The filler for a crack-resistant, drying type joint compound, consists of calcium sulphate dihydrate synthetically produced from the citric acid process and further processed to have a particular particle size distribution.

Armor structure formed from plastic
Hale, F.D. and Crowder, C.H. (West Point PeppereU Inc) US Pat 4 048 368 (13 September 1977) The substrate for an offset printing blanket comprises a woven fabric of spun warp fibres formed from an aromatic polyamide and f'fll fibres made of polyester; the warp fibres have a tensile strength of at least four
By-product gypsum Idlers for micafree joint compounds
Polyetherirnide composites White, D.M. (General Electric Company) US Pat 4 049 613 (20 September 19 77) The composite comprises 40-85% carbon fibre of elastic modulus greater than 14 GN/m 2 and tensile strength greater than 700 MN/m 2 and 15-60% of polyetherimide.
Brewer, W.E. and Zimmer, F.V. (K-Krete Inc) US Pat 4 050 950 f27 September 1977) The fill material consists of 2-6% Portland cement, 2-10% fly ash, 70-90% aggregate and 5-15% of water. The material is sufficiently flowable that tamping or vibrating is unnecessary; also the material has a concrete-comparison 28-day strength of less than 1 MN/m 2 so that it can easily be re-excavated.
Composite batt and method for producing same Sumner Buck, G., Jr., Weyker, R.G. and Ward, A.G. (Fiberlok Inc) US Pat 4 050 977 {27 September 1977) The batt is made by dispensing a particulate copolymer of vinyl chloride and vinylidene chloride onto open webs of cotton or polyester fibres. The webs and eopolymer are stacked alternately and then heated to a temperature between the melting
