An internal lining for ducts (C) is provided by introducing into one end of the duct an assembly (E) which comprises a sleeve (5) and an inflatable system (2) and which is provided with heating means for applying a sheath (1) impregnated with a resin against the inner wall of said duct (C). After partial polymerization at least of the resin, the sheath (1) adheres to the inner wall of the duct. Th...

The thread splicing device in which the two overlapping and in line ends and combined pneumatically, holds the tips of the thread ends freely and uses two air jets to interweave them. Before splicing, the ends of both threads are reverse twisted, being clamped at positions spaced away for the thread tips, the two jets being spaced apart to produce the rotation. The thread splicing member (101) has...

A tire having a pair of axially spaced-apart bead regions each reinforced by an annular bead hoop around which one edge of a carcass reinforcing ply is wrapped and a filler strip positioned in the axially outer region of the bead. The filter strip which extends circumferentially around the bead, has one edge radially inwards of the bead hoop and one edge axially outwards of the bead hoop character...

A gasoline composition contains a minor amount of at least one of a specified group of quaternary ammonium hydroxides for decreasing or reversing the octane requirement increase (ORI) for a fuel-fired spark ignition internal combustion engine. Tetrabutylammonium hydroxide and tricaprylicmethylammonium hydroxide are two preferred compounds for use.

A differential which includes a housing (1a, 1b) through which axially extend two shafts (4, 5) for driving the driving wheels of the vehicle, sun gears (7, 8) mounted in the housing (1a, 1b) in coaxial relation to the shafts (4, 5) and connected to rotate with the latter, planet gears (13, 14) journalled in the housing to rotate about a shaft (15) perpendicular to the two shafts (4, 5) and fixed ...

A crystal clear paint spray booth barrier coating comprising an aqueous solution of polyvinyl alcohol is disclosed. The polyvinyl alcohol may include a foam depressor for spray application of said coating. Fluorocarbon and non-ionic surfactants are disclosed for providing a smooth coating surface and improving the transparency of said coating. A polyacrylate thickener may be included to facilitate...

A process for producing microspherical cured phenolic resin particles having a particle diameter of not more than about 100 mu m, which comprises reacting a novolak resin, a phenol and an aldehyde in an aqueous medium in the presence of a basic catalyst and an emulsion stabilizer. Novel microspherical cured phenolic resin particles are produced by this process. The resin particles have excellent ...

A continuous process for the production of methacrylic acid ester of a C1 to C4 saturated aliphatic alcohol in the presence of a catalyst is disclosed. This process contemplates continuously introducing into a plug-flow reactor a feed stream containing methacrylic acid, a C1 to C4 saturated aliphatic alcohol in stoichiometric exesss relative to the methacrylic acid present, an esterification catal...

The resin-impregnated fibrous sheet consists of a stitched fibrous mat and a polymeric resin distributed throughout the mat, to form a resin-impregnated sheet which has a uniform bulk wt. at all points. The apparent density of the sheet is lower than the actual bulk wt., and the sheet is thus porous. The impregnated sheet has filaments which are both coated and uncoated with resin. The sheet is u...

The adhesive properties of polyolefin products are improved by submitting said products to a surface modification process which includes the following steps: A) application of a layer of one or more photosensitive materials selected from: 1) chloroparaffin containing 5 to 80 wt% of chlorine and having an average molecular weight greater than 200; 2) vinyl chloride homopolymers and copolymers, ...
