Method and apparatus for assembling a tire carcass comprising a precarcass band and a pair of inextensible bead rings. The band is built and consolidated on a form having a rigid cylindrical surface. The band includes at least one cord or wire-reinforced ply and one or more tire liners of a rubbery gum, and may include additional tire components, in particular the components which will form the si...

Hygiene material, for example lavatory paper, comprises a layer which in use is substantially water- impermeable and after use and when placed in water at least partly dissolves to give a reduced wet strength. A further layer of liquid-absorbent material is laminated to the layer. The layer 10 may be liquid- absorbent paper coated or impregnated with material having a transient water-insolubility ...

1. Article, in particular of flexible material, which during its designated use directly contacts the skin or the mucous membrane of the wearer and which at least in its area contracting the skin or the mucous membrane of the wearer during its designated use is provided with a layer which consists of metal, in particular aluminum or a noble metal, preferably silver, or which consists of metal part...

A process of treating coke oven doors and jambs with a material containing micro micron particles of graphite in a liquid carrier is described that forms a penetrating lubricating adhesive coating on the coke oven doors and jambs which acts to prevent leakage of tar and other coke by-products as heretofore common in the art and the resultant inability of maintaining a sealing relation between the ...

1. A wheel cylinder comprising a body (12), in the interior of which a bore (14) is formed, with at least on actuating piston (16) being slidably mounted in the bore at one end thereof and bounding a pressure chamber (20) with the latter, said actuating piston (16) being adapted to be movable towards the exterior of the bore for urging a first shoe (22) of a drum brake, said cylinder comprising a ...

Low-density crosslinked propylene polymer foams are prepared by mixing a propylene polymer with up to 20% of its weight of low molecular weight liquid polybutadiene(s) containing at least 35% by weight of 1,2-vinyl- polybutadiene and from 10 to 100% of its weight of EPDM rubber, EPM rubber or chlorinated polyethylene, together with a crosslinking or foaming agent, irradiating the mixture for cross...

A foamable phenolic resole composition is foamed and cured with an acid curing agent which is an anhydrous aryl sulfonic acid which has a pKa of less than about 2.0 and which reduces the compatibility of the resole with water, e.g. benzene, toluene or xylene sulfonic acids. The phenolic foam formed has cell walls which are substantially free of perforations. The preferred anhydrous aryl sulfonic a...

A multizone element, for quantitative analyte determination in whole blood, containing a porous spreading zone separated from a reagent zone by a barrier zone, said barrier zone comprising a non-porous film comprising a polymer of: from 30 to 95 percent by weight of polymerized monomer having the structure from 0.25 to 30 percent by weight of polymerized monomer having the structure

The invention provides an additive-containing polyolefin having an inner bead of a first polyolefin and an outer adherent coating of a second polyolefin encapsulating the additive.

A method for a condensate of an aldehyde compound and a phenol compound, said method comprising dispersing a viscous condensate obtained by the reaction of an aldehyde compound with a phenol compound into cold water or hot water by the aid of a dispersing agent, and then solidifying said condensate.
