Abstract: A vehicle suspension with an airspring of the type with a flexible sleeve forming a chamber portion and a rolling lobe portion. The chamber portion is attached to a tilted closure and the rolling lobe portion of the airsleeve is attached to a piston that is transversely moved which introduces a shear force into the airsleeve and increases a surface area on an upward tilted side of the sleeve so as to provide side load compensation and where the axial length of the rolling lobe is substantially equalized to enhanced flexural life. A method of imparting a side load force with an airspring fastened between a fixed member and reciprocating member of a vehicle suspension, is provided by tilting a closure member of the airspring, transversely moving a piston connected to a rolling lobe portion of the airspring while distorting a chamber portion of the airspring, and eccentrically offsetting the piston in a manner that tends to equalize an axial length of a rolling lobe.

Abstract: A belt tensioner of the Zed type with a pivot-arm attached to an off-set cylindrical member supported by sleeve-type bushings with axially spaced-apart bearing surfaces disposed over a pivot where the bearing surfaces have an axial length that is sized for an average pressure contact. The tensioner may include a spring activated damping mechanism with a brake shoe having oppositely facing inside ramp surfaces which operate in such a manner to provide a normal force that is greater than a spring force applied to the brake shoe.

Abstract: Polyfluorocarbon/elastomer bonded laminates are disclosed. Flexible, durable chemical-resistant hose for use in industrial applications, and improved construction for such hose including inner tube members characterized by a dual-layer feature employing such laminate, is also disclosed. This feature comprises an adhesive elastomeric composition which bonds a polyfluorocarbon thermoplastic veneer to a substantially non-polar chemical-resistant carbon-based elastomeric or thermoplastic elastomeric outer layer. The adhesive elastomeric composition useful in the present invention comprises unsaturated polymeric dicarboxylic acids, or derivative adducts, of ethylene propylene diene terpolymer.

Abstract: A tensioner with a pivot-arm that is free to move toward a belt of a belt drive system to tighten the belt and is also free to move away from the belt a predetermined amount to slacken the belt and adjust belt tension while avoiding tooth jump in extreme torque reversal situations. An adjustable stop is provided to restrict movement of the pivot-arm and inhibit tooth jump as the tensioner pulley moves to slacken the belt.

Abstract: A method of making a moldable, nonwoven composite material. The method includes blending a mix of first fibers and second thermoplastic fibers. The second fibers have a melting point lower than that of the first fibers and comprise approximately 40-80 percent of the blend. The blend is then processed into a fibrous batt. The batt is then consolidated into a nonwoven structure with the first fibers being thoroughly intermixed with the second fibers. The nonwoven structure is then heated to a temperature below the melting point of the first fibers and above the melting point of the second thermoplastic fibers to substantially liquefy the second fibers and form a thermoplastic resin. The heated nonwoven structure is compressed to flow the liquefied resin to displace air voids in the nonwoven structure and encapsulate the first fibers. Finally, the nonwoven structure is cooled to form a composite material having substantially reduced air voids therein with the first fibers thoroughly encapsulated by the resin.

Abstract: A process is provided for producing elastomeric compositions by forming a mixture of polymeric material, a reinforcing agent, a processing aid and a vulcanizing agent. The process of the invention is continuous and includes the repeated, sequential steps of admixing the polymeric material along a first mixing zone defined by a space wherein the gross energy applied induces a first operating temperature range. The mixture of the first zone is continuously passed into and through a second mixing zone while adding and admixing the reinforcement agent and processing aid therewith, the second mixing zone being defined by a space wherein the gross energy applied induces a second operating temperature range. The mixture of the second zone is then continuously passed into and through a third mixing zone while adding and admixing the vulcanizing agent therewith, the third mixing zone being defined by a space wherein the gross energy applied induces a third operating temperature range.
