Abstract: The present invention is directed to compositions and processes for their use that ameliorate the appearance of bruises, making them less cosmetically unappealing. The composition functions by acting both as a humectant and occlusive agent attracting water, returning the skin surface to a smooth state and holding water in place. The re-establishment of a homeostatic state in the skin results in a rapid dissipation of the negative cosmetic effects of the bruise on the skin.

Abstract: Method and apparatus for manufacturing a composite insulator which includes an FRP core rod covered by a sheath and provided with a plurality of sheds which are made of an electrically insulating polymeric material. The sheds are set on a support member arranged on a downstream side of an extruder. The extruder is fed with a core rod and extrudes a polymeric material to form a sheath on the core rod.

An assembly is thus formed which includes the core rod, sheath formed on the core rod, and sheds transferred onto the sheath. The assembly is then heated to vulcanize the sheath and adhere it to the core rod and the sheds.

Abstract: A system for curing composite structures. A hollow bladder having opposing open ends is secured within a metal pressure vessel so as to define an annular space within the vessel surrounding the bladder. The open ends of the bladder are sealably attached to opposing entrances formed in the pressure vessel so that the bladder is sealed from communication with the vessel and is accessible through the opposing openings. An uncured composite part can be inserted into the bladder. Preheated and pressurized fluid is circulated through the annular space and thus around the bladder in order to cure the composite part. The composite part may also be encapsulated within a forming bladder member which is then removably inserted into the pressure bladder.

Abstract: Disclosed are expandable bladders for use in curing presses for rubber compositions such as pneumatic tires. The bladders are a crosslinked elastomer comprising an isobutylene rubbery polymer. The bladder composition includes corn oil which improves the release characteristics of the cured bladder from a tire innerliner cured in contact with said bladder. The improved release characteristics have been observed to allow rubber compositions such as tires to be molded with fewer defects caused during release of the bladder from the tires or caused by abraded or deformed bladders. The use of corn oil also has been observed to increase the useful life time of the bladder allowing more tires to be cured without changing bladders. A preferred isobutylene rubbery polymer is a brominated copolymer of isobutylene and p-methylstyrene. The bladder compositions have also been observed to have an enhanced flexibility due to the corn oil.

Abstract: According to the invention, calibrated rings are obtained by superficially vulcanizing extruded or profiled extrudate at the exit of an extrusion head (T), then by cutting this vulcanized extrudate into portions by means of a conical cutting device (C), subsequently by butting the two ends, in the respective form of a conical tip and a funnel, of each portion (t) together under hot conditions and under a controlled pressure, in order to obtain a ring blank which is then engaged between the half-cavities of a mold (Mo), where it undergoes shaping and vulcanization by the heating of the latter and thereafter deburring as a result of a shearing action produced by a push device (D) causing the half-cavities to slide in the closed position in the frame of the mold, before causing the opening of the latter by means of a device (G) and the release of the calibrated and superficially clean ring obtained.

Abstract: The present invention contemplates a method of continuously forming a layered composite material into a rigid structure as the material is moved from an upstream location to a downstream location. The uncured layered composite material is pulled from a supply at the upstream location through a forming die to form the material into a structural member having a desired shape. The member is moved downstream into a heating die where it is at least partially cured. After it leaves the heating die it is cooled and continues to move downstream where it is cut into suitable lengths. The cooling can be accomplished by a cooling die located downstream from the heating die. A liner is provided within the dies having the same shape as the structural member through which the structural member slides as it moves in the downstream location.
