Abstract: An electrically actuated, hydraulic power steering system is provided. The steering system includes a hydraulic pump for generating hydraulic pressure, a hydraulic fluid reservoir, a hydraulic cylinder, and a control valve arrangement that selectively connects the hydraulic cylinder to the pump and the hydraulic fluid reservoir. The control valve arrangement is characterized during the on-center position by a first and a second chamber of the hydraulic cylinder being in fluid communication with each other but not with the fluid reservoir. In one embodiment, the steering system has a steering sensor, a control box, and two pressure accumulators for providing at least two levels of steering assist.

Abstract: A hydraulic power steering system for use in a vehicle to eliminate energy waste when power assist is not required is disclosed. The hydraulic power steering system includes a pulley powered by a crankshaft in the vehicle, a clutch operably connected to the pulley, a hydraulic pump operably connected to the clutch, and controlling means for engaging and disengaging the clutch with the pulley and the hydraulic pump to provide hydraulic power to the system. It also includes a hydraulic accumulator to provide system pressure for short periods before the pump clutch can engage in response to a steering input.

Abstract: The stringed instrument includes an aluminum head formed of a stepped annular flange with a shoulder intermediate smaller and larger diameter flange portions. A groove is formed in the shoulder to enable the smaller diameter flange portion to vibrate relative to the larger diameter flange portion. A membrane is stretched over the smaller diameter flange portion. The arm of the instrument is secured solely to the larger diameter flange portion by neck mount brackets screw-threaded to the head. The brackets permit angular adjustment of the arm relative to the membrane of the head. A full fingerboard capo is slidably mounted to the neck underlying the fretboard and has an arm spring-biased to engage the strings and to maintain the capo in selected positions along the length of the arm. A fifth string capo is slidably mounted to the fretboard and has a spring to maintain it in selected longitudinal position along the fretboard.

Abstract: A trapezoidal endless power transmission belt structure is provided which is made primarily of elastomeric material and has a pair of oppositely arranged surfaces disposed in spaced relation to define an outside and inside surface of the belt structure and has a load-carrying section arranged midway between the inside and outside surfaces. The belt structure has a tension section and a compression section which are of similar construction and each is comprised of a plurality of layers including a fiber-loaded layer disposed adjacent the load-carrying section and a fabric layer disposed remote from the load-carrying section; and, the fabric layers and fiber-loaded layers cooperate to assure that the belt structure has longitudinal flexibility yet has transverse rigidity or stiffness sufficient to enable the belt structure to be operated in associated sheaves free of shear planes parallel to the load-carrying section.

Abstract: An improvement in the initial folding operation of the hemming machine disclosed in U.S. Pat. No. 4,066,025 by the substitution of a live angular belt extending across the path of advancing overhanging hem material in place of the prior fixed curved guide which led the material to a folded under position.

Abstract: A tensioner for a power transmission belt that is adapted to be operated in an endless path and a method of making the same are provided, the tensioner comprising a mechanical spring unit operatively associated with a support unit and a belt engaging unit for urging the belt engaging unit relative to the support unit and against a belt with a force to tension the belt, and a fluid dampening unit operatively associated with the support unit and the belt engaging unit to dampen the movement of the belt engaging unit relative to the support unit in at least one direction of movement thereof, the fluid dampening unit comprising a rotary dampening unit and being coaxially aligned with the spring unit.

Abstract: A tensioner for a power transmission belt or the like that is adapted to be operated in an endless path and a method of making the same are provided, the tensioner comprising a support unit for being fixed relative to the belt, a belt engaging unit carried by the support unit and being movable relative thereto, a polymeric spring unit being operatively associated with the support unit and the belt engaging unit for urging the belt engaging unit relative to the support unit and against the belt with a force to tension the belt, and a coiled mechanical spring also being operatively associated with the support unit and the belt engaging unit for urging the belt engaging unit relative to the support unit and against the belt with a force to tension the belt whereby the polymeric spring unit and the mechanical spring combine to define the tensioning force for the belt while the polymeric spring unit additionally tends to dampen the movement of the belt engaging unit relative to the support unit, the mechanical spr
