摘要： 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.

摘要： 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.

摘要： 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.
