Abstract: 1394036 Crimping fibres and yarns AKADEMIE DER WISSENSCHAFTEN DER DDR 28 June 1973 [28 June 1972] 30729/73 Heading D1F In the production of synthetic e.g. nylon 6, filaments textured by a false-twist crimping process, the extruded filaments are stretched in at least two stages. The first stage or the first and subsequent stages (but excluding the final stage) is effected in a conventional stretching device and the final stage is effected separately in the texturing (falsetwisting) zone. The filaments are stretched in the operations preceding the final stage by 90-97% of the value normally necessary to produce the required strength and elongation values for the filaments. The filaments may be fed to the texturing zone with a changed entry rate and/or removed therefrom with a changed output rate so that the ratio therebetween ensures a required final titre of the filaments.

Abstract: 1,260,798. Laminates. VEB KOMBINAT TECHNISCHES GLAS ILMENAU. 29 June, 1970, No. 31303/70. Heading B5N. [Also in Division D1] Method for improving the interfacial adhesion of inorganic fibre materials, especially desized fabrics of glass fibre materials to resins, wherein inorganic fibre materials are treated with a solution of an epoxy silane and, for the production of composite materials, a resin specific coupling agent of the silane type, containing unsaturated radicals, is added to the resin. Vinyl or methacrylate silane is used as the silane in the case of the use of unsaturated polyester resins and epoxy-silane is used for epoxide or phenolic resins. The inorganic fibre materials may also be impregnated with a solution comprising an organo-silane, preferably containing unsaturated radicals, and a chromium salt of an organic and/or inorganic acid. To improve the wettability by the resin, the inorganic fibre materials are treated with coupling agents containing polymeric compounds and/or phenol derivatives and/or silicic acid compounds and/or inorganic pigments. It is possible to add, as polymeric compounds, water soluble and/or water dispersible polymers and as phenol derivatives dihydroxy-benzenes, and as silicic acid compounds aqueous dispersions of silicon dioxide and/or silicic acid ester dispersions and/or dispersions of condensed silicic acid esters, and as inorganic pigments titanium dioxide, calcium carbonate and antimony trioxide preferably in dispersed form. For the production of composite materials, the above treated inorganic fibre materials are impregnated with a resin either in pure form or modified with silane. Examples of polymeric compounds are polyvinyl pyrrolidone solutions, epoxide resin dispersions, dispersions of unsaturated polyester resins; examples of phenol derivatives are resorcinol, precondensates or condensates of resorcinol with formaldehyde as solutions or dispersions and examples of resins are thermosetting or thermoplastic resins and silicone resins or elastomers. The fabric of inorganic material is first desized, preferably thermally and then impregnated with mixtures of the described coupling agents and additives, whereupon it is dried and set at an elevated temperature.

Abstract: 698,350. Furs. HOWARTH, S. W. Nov. 15, 1951. [Dec. 30, 1950] No. 31675/50. Class 76. A machine for liberating fur from fur-bearing skins and cleansing the liberated fur comprises a cutting device, which may be of known type, from which the fur is conducted by means of an air stream to a cleaning device for removing dust from the fur. As shown the cutting device is provided with cutting blades 3 co-operating with a fixed blade 4. A pair of rollers 5 feed the skins to the cutting device whereupon the leather is cut into fine shavings and a small suction trunk 6 removes dust freed on cutting. A suction nozzle 7 removes fur as soon as it is liberated, the leather being separated by fixed blade 4, and the fur is conveyed via trunk 8 and air blower 10 to a chamber 15 containing oppositely rotatable drums 18 having perforated peripheral surfaces and being divided into a plurality of independent sector-like compartments 21 which communicate in succession with an exhaust trunk 22 by means of ports 23. As each sector comes into communication with the exhaust trunk, fur is collected on its peripheral surface and when the sector moves out of communication the fur falls away on to a conveyer belt 17. Excess fur is removed from the belt by brush 24 and brush 24<SP>1</SP> brushes the remaining fur on to a perforated roller 27 from which the fur is conveyed by means of feed rollers 31 to a picker 34 from which the fur is carried by means of an upward air current created by the picker to a second perforated roller 28, the said current being sufficiently strong to carry the fur, but not heavy substances such as pieces of leather and matted tufts of fur.
