Abstract: Immunoenzymatic conjugate consisting of glycosylated labelling enzymes in copolymer form and substances having immunological activity.Method for the production of the conjugates according to the invention and use of the said conjugates in diagnostic kits.

Abstract: Stampable reinforced thermoplastic sheet, at least one face of which comprises, from the outside to the inside, at least three successive layers abc, in which:a is a matrix comprising a thermoplastic resin reinforced by at least two fillers of different nature and/or type chosen from fillers of the lamellar type and of the spherical or substantially spherical type,b is an interfacial binder chemically compatible with the thermoplastic resin of a and having, with respect to the latter, a lower viscosity at the temperatures at which the sheets are produced and used, andc is a reinforcement comprising a needled glass mat.Articles obtained from the sheets by stamping.

Abstract: An apparatus for the manufacture of sections of thermoplastic resin reinforced with continuous fibers. The apparatus includes coating rovings, having their fibers previously arranged in the form of a sheet by passage through a baffle zone having at least one transverse baffle, in a coating zone fed with a molten thermoplastic, then, to ensure impregnation of each of the fibers of the rovings, the coated rovings are passed into a forced impregnation zone having at least two baffles parallel to the baffle in the baffle zone prior to passing into the channel for shaping the final product.

Abstract: In the process for the manufacture of a polyamide composite material reinforced with long fibers, the improvement comprising impregnating the fibers with a polyamide oligomer or prepolymer, heat-treating the impregnated fiber to increase the length of the polymer chain, and then shaping the impregnated fiber by pultrusion.

Abstract: The invention is a process for the manufacture of sections of thermoplastic resin reinforced with continuous fibers and the equipment for carrying out the process. The process consists of coating rovings, having their fibers previously arranged in the form of a sheet, in a coating zone fed with a molten thermoplastic, then, to ensure impregnation of each of the fibers of the rovings, the coated rovings are passed into a forced impregnation zone prior to passing into the channel for shaping the final product.
