Abstract: A batchwise process for dyeing hydrophobic fibres at 110.degree. C. to 135.degree. C. with a disperse dye in the presence of an adduct of an average of 1 to 4 molar proportions of ethylene oxide, propylene oxide or styrene oxide or a combination of these oxides with 1 molar proportion of a phenol compound having the formula ##STR1## in which n is a number from 1 to 4,R.sub.1 is hydrogen, chlorine an alkyl group with 1 to 8 carbon atoms, an alkoxy group with 1 to 8 carbon atoms or an alkenyl group with 2 to 8 carbon atoms.R.sub.

Abstract: A method for the production of a stretched multi-cellular polyolefin article. A composition comprising a blend of a crystalline polyolefin and about 2-50% by weight of a metal resinate is formed into a shaped article. The shaped article is either uniaxially or biaxially stretched at a temperature between the glass transition temperature and the crystalline melting point of the polyolefin resin to form a multi-cellular article.

Abstract: A process for the manufacture of a multicellular stretched sheet which comprises melt compounding a thermoplastic matrix polymer and an additive comprising a polymeric or non-polymeric organic compound or a metal salt of an organic acid, forming the blend into a shaped article and stretching the article at a temperature within the normal orientation temperature of the matrix polymer and below the glass-transition temperature of the polymeric additive or below the melting or softening point of the non-polymeric additive.

Abstract: A composition which can be formed into a shaped article and stretched to produce a multicellular stretched article comprising a blend of a thermoplastics material and a metal resinate or a resin ester.

Abstract: A surface coating process which comprises passing a surface to be coated past or through an excited cloud of coating material on an alternating electric field between two electrodes, one of which comprises a rotating drum onto the surface of which is metered a supply of electrically chargeable coating particles.

Abstract: New piperidine derivatives of 1,3-pyrimidine and 1,3,5-triazine are used as stabilizers for organic materials, especially for polymers.

Abstract: A self-flanging nut construction utilizing a tubular body having a laterally extending flange at one end and an opening therethrough, said opening having a first portion and a second portion of differing cross sectional areas, the first portion being formed with a thread and the second portion defining a riveting flange. A plurality of circumferentially spaced serrations or ribs are provided on the periphery of said body adjacent said flange. When the nut is placed adjacent a sheet metal body having an opening therein with the opening in alignment with the opening in the nut and the nut is forced against said plate, the metal surrounding said opening in said plate is first deformed axially of the opening to form a tubular portion and thereafter the riveting flange is deformed laterally outwardly over the end of the tubular portion formed on said plate.

Abstract: Method of making a beaded retro-reflective material comprising embedding beads in a generally planar plastic matrix and embossing the material so that axes of exposed portions of the beads lie at varying angles to the general plane of the matrix.

Abstract: 1. A surface-inhibited propellent charge comprising a charge of propellent composition having bonded to at least part of its surface an inhibiting layer comprising silicone rubber supported on biaxially-stretchable glass fabric.

Abstract: Apparatus for use in the production of a tube of organic thermoplastic polymeric material wherein the peripheral portions of the calibrating disc assembly and the seal that contact the wall of the tube comprises a liquid absorbent material; and a method of producing the above tube.

Abstract: A process for the colouration of polyacrylonitrile textile fibres, wherein said fibres are coloured by printing or pad-steaming with a cationic dye in the presence of a carrier consisting of least one compound having the formula ##EQU1## in which Y is an oxygen or sulphur atom and m is a number from 1 to 2, obtaining on said fibres a rapid fixation of the cationic dye and a high colour yield.

Abstract: Process for the colouration of acid-modified synthetic textile fibres, particularly polyacrylonitrile fibres or basic dyeable polyester fibres, wherein said fibres are coloured with a cationic dye in the presence of a compound of the formula ##EQU1## wherein R is a chloro-substituted phenyl group, Z is hydrogen or methyl and n is an integer from 1 to 3, obtaining on said fibres a rapid fixation of the cationic dye and an outstanding colour yield.
