PURPOSE:To make it possible to assemble a shell-type needle roller bearing without using any special jig, by forming a tapered surface having a width 15% or more of a thickness of a shell and an angle of 10 deg. to 30 deg. on an inside diameter side of at least one of folded portions formed at outside both ends. CONSTITUTION:A shell-type needle roller bearing 1 is formed with folded portions 2A an...

The curable resin composition of the present invention consists of a curable resin and the spherical microparticles of cued silicone rubber obtained by the curing of an addition reacting silicone rubber composition, wherein the silicone rubber composition also contains an epoxy compound having an aliphatically unsaturated group. Furthermore, because the microparticles are prepared from an aqueous ...

Liquid bitumen at a temperature of 120 - 160C is mixed with 1-3% by weight of water in a mixing device (8) at a pressure which is higher than the saturation pressure of water vapor at the temperature of the hot bitumen. From the mixing device the mixture is allowed to expand through a valve (10) such as a throttle valve, the resulting evaporation of the water in the mixture causing the desired ...

A composite binder consisting, on the one hand, of an aqueous emulsion of at least one hydrocarbon binder and, on the other hand, of at least one hydraulic binder, which is characterised in that it also contains at least one adjuvant intended to control the rate of setting of the hydraulic binder in order to obtain a liquid product with a viscosity of less than 1 Pa s.

A thermosetting resin composition of an epoxy resin mixture of 1,2 epoxy resin having at least two epoxide groups per molecule and a polyglycol diepoxide having viscosity of 2,000-5,000 centipoises at 25 DEG C. and in addition small but effective amounts of both a catalytic hardener and an accelerator has special utility in the production of composite molded bodies of electrical insulation having...

This invention is directed to novel crystalline chain extended polymers containing segments of crystalline poly(aryl ether ketones). The novel materials are easy to prepare and display excellent toughness, fabricability and very good high temperature and solvent resistance.

This invention provides a process for deacidifying paper by contacting the paper with hydrocarbon or halocarbon solutions of certain magnesium and/or zinc alkoxyalkoxides which may have been treated with carbon dioxide to yield low viscosity solutions.

A unitized grease seal (10). The seal member has a one-piece metal case (15), a molded elastomeric member (16) bonded to the metal case (15) and providing a series of spaced-apart inwardly extending retaining portions (38). The elastomeric member (16) also has two diverging lip portions (40-41) with a cavity (44) between them, one providing a grease retention lip (40) having small spaced-apart sha...

A flexible, resilient sealing strip for motor vehicle doors, comprises a U-shaped gripping portion (2) enabling the strip to be fixed on a projecting part of the door, and a tubular sealing portion (4) of a cellular elastomer co-extensive with the gripping portion (2) along the length of the strip such that when in use, the sealing portion (4) is compressed between the door and the frame providing...

In a fuel injection system incorporating a distribution type fuel injection pump, wherein the amount of fuel in each fuel injection is controlled by the time duration from the stoppage to the resumption of the venting or spilling of the pumping chamber, the time duration is electronically calculated according to engine rotational speed and accelerator pedal opening amount as a rotational angle of ...

Transformed human lymphocyte cell lines have been produced which secrete human monoclonal antibodies to serotypic determinants on LPS molecules of gram-negative bacteria. These antibodies have been found to be protective against lethal challenges of the homologous bacteria. Pharmaceutical compositions containing these antibodies and their prophylactic and therapeutic use in the management of gram-...
