Abstract: A method and composition which provides both thermal; control and electrostatic discharge protection to bodies in the space environment. The composition comprises: (a) a chosen polymer or resin that forms a polymer that is an electronic insulator and is suitable for space applications; and (b) a selected lithium salt as a dopant wherein said composition, when formed into a film or coating, provides a semiconductive film or coating having a volume resistivity of about 10.sup.6 to 10.sup.11 ohm-centimeter and a value of solar absorptance/total normal emittance within the range of about 0.305 to 0.595. In an alternative embodiment, the composition may optionally include tantalum pentoxide.
Abstract: A method for treatment of carbon fibers for reinforcement comprises the step of coating or impregnating carbon fibers with an emulsion of epoxy resin having colloidal silica added thereto so as to harden the same. The carbon fibers treated in this way exhibit high bonding strength with respect to a concrete matrix, making it possible to obtain excellent carbon fiber reinforced mortar and concrete.

Abstract: A method of manufacturing a rubber or plastic-coated roller such as a fixing roller to be used in the thermal fixing part of an electrophotographic copying machine.
Abstract: A method for making elastomeric cushion pads which can be used in off-the-road vehicles and in the draft gears of railroad cars. The method includes solidifying a molten mass of the elastomer under a pressure of at least 1000 psi to form an elongated slug of the elastomer which is then cut into a plurality of unfinished cushion pads which are then individually momentarily compressed to remove any permanent set or deformation of the pads which occurs when an uncompressed pad is initially compressed.
Abstract: Through a method for production of piled mats (1-3) with rubber backing on a vulcanizing press (P) with a stationary vulcanizing heater plate (8) where articles (1-3) to be vulcanized are conveyed into position in and out of the press (P) from one and the other side of it using a heat conducting conveyor belt (9), each of the vulcanized articles (1) will be conveyed as soon as it leaves the press (P) on the conveyor belt (9) after the press vulcanizing operation to one of two cooling and degassing stations (KA1, KA2) while at the same time a next unvulcanized article (2) is conveyed on the same conveyor belt (9) into its position in the press (P) while said next article (2) is conveyed after the press vulcanizing operation to the second of the two cooling and degassing stations (KA1, KA2) while at the same time a next unvulcanized article (3) is conveyed on the conveyor belt (9) into its position in the press (P) in connection with which each article at the cooling and degassing stations is removed after the
Abstract: A process for molding an outer sole of elastomer and an inner sole of a mixture of isocyanate and a polyol reacting into polyurethane to shoe uppers includes a vertically movable upper cross block supporting a pivotably mounted mold carrier with a heatable first mold part at one end for the molding of outer soles, and a lower, vertically adjustable cross block has a mold plate confronting the first mold part. The first mold part releases the molded outer sole on to the mold plate, the mold carrier is pivoted such that a cooled second mold part at the opposite end thereof overlies the molded outer sole which is then transferred to the second mold part, the mold carrier is again pivoted to confront the molded outer sole to a shoe last supported shoe upper, and an inner sole mold cavity is formed with the molded outer sole juxtaposed to the last supported shoe upper, and by an opposed pair of lateral mold elements closed about the shoe upper.
Abstract: A method of manufacturing a closed, hollow toroidal structure having a rigid internal annular plate includes treating one annular surface of the plate with a release coating, applying to the other annular surface of the plate an adhesion promoting coating and positioning the plate within a mold having a generally toroidal internal cavity. Next, a fluid conduit is juxtaposed partially within the internal cavity of the mold adjacent to the annular plate and partially outside the internal cavity of the mold. The mold cavity is then filled with an elastomer followed by curing under heat and pressure.
