摘要： An apparatus is provided including an endless conveyor and a plurality of elongated mold elements are mounted from the conveyor and project laterally outwardly of the latter. The apparatus defines coating, heating, and cooling stations through which the mold elements are successively moved and the coating station includes structure whereby the outer end portions of the mold elements may be coated with plastisol. The heating station includes structure by which the mold elements, with the plastisol coating thereon, may be exteriorly and interiorly heated to the cure temperature of the plastisol, the cooling station includes structure for externally and internally cooling the mold elements. The apparatus further includes structure by which the mold elements are rotated about their longitudinal axes during movement of the mold elements through the coating, heating and cooling stations, and structure for rapidly spinning the mold element after they have been coated at the coating station and before they pass through the heating station. Structure also is provided for powder coating the mold elements subsequent to movement thereof through the cooling station while additional structure is provided for automatically removing the coating after being powdered.

摘要： An apparatus for sealing at least a portion of the urinary tract to prevent the unwanted discharge of urine includes a body member with a tubular member, encircled along its length by an overcoat layer, that encases a fluid, forming a cavity. The body member, with its tubular member and overcoat layer are elastically deformable from an initial “rest” or “relaxed” state, when outside of the body, where at least a portion of the overcoat layer is of a diameter equal to or greater than that of an undilated urethra. A stylet may be placed into the tubular member to serve as a guide, for elongation of the body member and to provide rigidly to the body member upon insertion into the urinary tract. There is also disclosed a method for making the apparatus of the present invention.

摘要： Prophylactic devices are made in an inert atmosphere by cooling mandrels on which the devices are to be deposited, dipping the mandrels into a polymeric material in a solvent/carrier and a mold release agent, rotating the mandrels during and after the dipping, and evaporating the solvent after dipping. The apparatus includes an air lock between a section in which these functions are performed and a section located in an air atmosphere for removing the devices from the mandrels, followed by cleaning the mandrels for use in a subsequent production run for making devices.

摘要： The invention provides mandrels for producing elastomeric components such as mammary implants. Specifically, the invention provides mandrels that include a mold, a shaft attached to the mold, and a drip retainer attached to the shaft. The drip retainers disclosed herein are configured to catch and contain fluids (e.g., elastomeric compounds dispersed in solvents) that run and/or drip off the mold and shaft, and to retain such fluids when the dipping mandrel is inverted. The invention also provides drip retainers that can catch and contain fluids (e.g., elastomeric compounds dispersed in solvents) when attached to a dipping mandrel, and can retain the fluids upon inversion of the dipping mandrel.

摘要： Pore-free rubber articles are prepared by dip-molding in a dipping medium that includes a vulcanizing agent, then by immersing the dip former in a heated liquid bath that is chemically inert. A particularly effective liquid bath is molten inorganic salt. In addition, the tensile properties of an article of vulcanized rubber can be improved to an unusually effective degree by immersing the already vulcanized article in a solution of a vulcanizing agent to cause the rubber of the article to absorb or imbibe the vulcanizing agent from the solution, and then immersing the rubber and the imbibed vulcanizing agent in a heated liquid bath to increase the degree of vulcanization.

摘要： A process for making a low molecular weight cellulose ether has the following steps: a) providing a high molecular weight cellulose ether; b) contacting it with acid to partially depolymerize it to a cellulose ether of a viscosity of about 100 cP or less; c) neutralizing the acid; d) repeating steps a)-c) to produce two or more discrete product batches of low molecular weight cellulose ether and produce at least one discrete product batch which is partially neutralized; and e) blending the two or more discrete product batches to form a combined product batch of low molecular weight cellulose ether of a pH of 4 to 6.8. The process provides a cellulose ether with reduced yellowing and discoloration.
