Abstract: A hose article for carrying volatile fluids, which can conduct and dissipate the accumulation of static electrical charges that are associated with such volatiles, which includes an elastomeric tube and outer sleeve and at least one reinforcement layer of fiber bundles sandwiched between the tube and the cover. Sandwiched between the tube and the reinforcement layer is a nontwisted yarn of fibers of carbon that runs in a direction generally lengthwise to the axis of the tube, and at the end of the tube makes electrical contact with a staple-shaped metallic connector, which in turn electrically contacts a metallic hose coupling, leading from there to an electrical ground.

Abstract: A reformable, shape retentive hose having a precured tube located in a hose sidewall, and a reformable rod inserted in the precured tube. A method for making hose by placing at least one precured tube in the sidewall of a hose during the time that the hose sidewall is formed, curing the hose assembly with the precured tube in the sidewall, and inserting a reformable rod in a portion of the precured tube.

Abstract: A reinforced hose and coupling assembly is disclosed that will withstand very high pressures without bursting. A modified seal ring eliminates shear planes in the wire reinforcement near the fitting end of the coupling and thereby reduces the possibility of failure of the hose coupling at high pressure. The assembly also incorporates the use of a fluoroelastomeric tube liner and fluoroelastomeric seals to prevent the permeation of H.sub.2 S gas into the anchoring matrix.

Abstract: A double-acting power transmission belt having a plurality of elastomeric teeth positioned along both its inner and its outer peripheral surfaces, each such tooth possessing a certain spring rate, and inner and outer jackets, respectively, formed over the teeth and over the land portions between the teeth at each of the inner and outer peripheral surfaces, said inner jacket cooperating with the associated teeth such that the spring rate of each jacketed tooth on the inner one of the peripehral surfaces is from 1.2 times to 3 times the spring rate of a corresponding non-jacketed tooth.

Abstract: A coupled hose assembly of the type including a coupling attached to a polymeric hose by pinching part of a hose end portion. A pliable adhesive is disposed in part of the coupling to define a substantially leakproof seal between the hose and coupling at an environment temperature falling at least within the range of about 135.degree. C. to about -40.degree. C.

Abstract: A precompounded formulation that acts as an adhesive layer when subjected to heat and pressure in contact with thermoplastics such as polyethylene or polyvinyl chloride and elastomeric materials such as EPDM or chlorobutyl rubber. The formulation incorporates a formaldehyde donor/acceptor system such as resorcinol and hexamethoxymethylmelamine. The formulation is further comprised of a blend of thermoplastic materials, the composition of which varies depending upon the type of material that the bonding layer is required to adhere to. The formulation will also adhere to thermoplastic elastomers (TPE) making it feasible to manufacture a hose article with elastomeric and thermoplastic layers bonded together by the formulation without the need to vulcanize the article. Heretofore, thermoplastic elastomers were thought to be incapable of adhering to dissimilar materials without the application of a tackifier or an adhesive or glue-like material.

Abstract: A toothed belt that has a tensile member of spirally wound cord where the operating pitch line of the belt is at least partially established by the cord which is made by twisting together at least two substantially zero twist, unequal denier yarn ends to form a ply, and twisting at least two of such piles together in the opposite direction to form the cord.

Abstract: A sealed gas recombining lead-acid cell with absorbed electrolyte is produced by assembling unformed plates and high porosity glass mat separator whose surface area is from 0.2-1.7 m.sup.2 /g, adding a limited quantity of acid into the cell, and then either prior to or after sealing of the cell electrochemically forming the plates of the cell in situ. High rate performance of the cell is significantly improved over cells using conventional high surface area glass separators.

Abstract: A reinforced, lightweight, flexible hose that is also abrasion and stain resistant. The hose properties, because of the component nature of the hose, can be varied to provide the most durable and economical hose for a specific application.

Abstract: A conductive elastomeric ink is described comprised of very fine nickel particles admixed in a silicone binder. The ink has utility in elastomeric switch control devices, printed circuits and the like.

Abstract: A surface of an elastomer mass subject to stress by a force supplying member is protected from abrasion and cracking by interposing a silicone rubber layer between the elastomer mass and force supplying member.

Abstract: A thread protector with a generally sleeve-like cylindrically shaped body that has a perforate sidewall and protuberances for retaining the body to a threaded member.

Abstract: An inflatable packer comprising an elastomeric tubular core, an outer cover, an annular reinforcement sheath sandwiched between the core and cover comprising a strength zone composed of strain-resisting elements of high modulus extending helically at alternate lay angles of less than 40.degree. with respect to the packer axis, and sleeve means to which the reinforcement is securely attached at each end of the packer. In one embodiment a transition reinforcement zone is interposed between the tubular core and strength zone to improve the flex properties and increase the life of the packer. In another embodiment an improved anchor means formed of a frusto-conical matrix encapsulates embedded reinforcement members.

Abstract: A preferably sealed lead-acid battery having a microfine glass separator pasting paper integrated with its adjoining plate, and the associated method by which the separator pasting paper is applied directly to the freshly pasted plate.

Abstract: A toothed power transmission belt with belt teeth having flank surfaces in the form of a tractrix curve and a belt sprocket with sprocket teeth having flank surfaces in the form of a tractrix curve, together, the belt and sprocket exhibiting smooth running and antiratcheting characteristics.

Abstract: An example of an elastomeric article embodying the invention is a composite, reinforced, vulcanized elastomeric hose, which includes a tube, an outer cover, a reinforcement layer, and a specially compounded interlayer interposed either between the tube and the reinforcement or the cover and the reinforcement. The inner tube (or in some applications, the cover) is composed of either a fluoroelastomer, fluoroplastic, polypropylene, polyvinylchloride, chlorinated polyethylene, or acrylonitrile polymer. The compounded polychloroprene interlayrer effects a strong bond to these materials. The tube and the cover are composed of materials not readily bondable to each other. The polychloroprene interlayer forms a strong bond to those layers it is in contact with when vulcanized.

Abstract: A liquid storage tank of the collapsible type that has an elongate body with a liner and cover that sandwich a twined reinforcement. The body has an intermediate tubular portion with a reinforcement arranged to allow radial growth. Two opposite end portions are interconnected by the tubular body and are reinforced with twined cords that generally radially enforce such end portions. An outlet is provided in one of the end portions.

Abstract: A belt and reinforcement for a V-block of a V-block belt is provided. The reinforcement has a generally U-shaped member with a lower beam member that interconnects diverging diagonal side members that each form a cantilevered portion. A means is provided in the cantilevered portion for retaining an upper beam member. The means is in the form of deformable sides that define a slot for receiving end portions of the upper beam member.
