    摘要： A reservoir for a hydraulic suspension system for a motor vehicle has two vents disposed diagonally opposite relative to the direction of travel of the vehicle. A level sensor and filter are formed which fit together and to the reservoir, with the level sensor extending through and beneath the filter. The bottom of the reservoir tapers so as to direct hydraulic fluid toward the hydraulic fluid pick-up of a pump which is mounted in a sidewall of the reservoir.

    摘要： Hydraulic cylinders made of fiber-resin composite materials have a central piston chamber section and bell-shaped internally threaded end sections. Cylinders are made by winding resin coated fibers over a mandril over which externally threaded sleeves are slipped and spaced apart so as to define the end sections. After curing the resin, the winding is cut in the areas of the sleeves to separate the cylinders. An expendable strip is wound onto the sleeves and in the cutting operation is cut into. A bearing, a seal cavity and an enlarged inside diameter at a piston rod end of the cylinder may also be provided using a method of the invention, with the cylinders being cut apart between the ends of sleeves and between the other ends of the cylinders.

    摘要翻译： 由纤维树脂复合材料制成的液压缸具有中心活塞室部分和钟形内螺纹端部。 气缸通过将树脂涂覆的纤维缠绕在心轴上而制成，其中外螺纹套筒滑动并间隔开以限定端部部分。 在树脂固化之后，在套管的区域中切割绕组以分离气缸。 将一个可拆卸的条带缠绕在套管上，并在切割操作中被切入。 也可以使用本发明的方法来提供在气缸的活塞杆端处的轴承，密封腔和放大的内径，其中气缸在套筒的端部之间和气缸的另一端之间被切割。

    摘要： A method of decrypting DRM encoded content in a DTV receiver involves receiving an encrypted license from a license server at the DTV receiver; providing a unique identifier for an integrated DTV SoC forming a part of the DTV television receiver; storing a secret key in an electronic fuse memory forming a part of the SoC, where the secret key is generated using an algorithm that utilizes the unique identifier for the SoC; where the received encrypted license is encrypted using the same secret key as is stored in the electronic fuse memory; decrypting the secret key using the key stored in the electronic fuse memory to produce a clear secret key; decrypting the encrypted license using the clear secret key to determine a content key; storing the license; and decrypting the DRM encoded content using the content key. This abstract is not to be considered limiting, since other embodiments may deviate from the features described in this abstract.

    摘要： A variable displacement hydraulic piston pump and servo displacement control which combines a rotary vane type actuator and a port plate to obtain both servo and actuation functions for a hydraulic piston pump. The control includes a construction which provides feel to the operator for how much work is being performed. The control also incorporates a failsafe mechanism so that the control is capable of transmitting torque to manually stroke the pump if charge pressure is lost.

    摘要： An apparatus for facilitating use of OCAP (OpenCable™ Applications Platform) standard in a host cable television device, the host cable television device having a connector consistent with certain embodiments has a removable module. An OCAP engine resides on the removable module suitable for execution of Java™ code as specified by the OCAP specification. A module side connector is affixed to the removable module, the connector being suitable for mating with the connector of the host device. The module side connector has connections suitable for carrying graphics video data from the OCAP engine to the host device suitable presentation to a video display. The module side connector further has connections suitable for carrying Java™ code instructions to the OCAP engine for execution. This abstract is not to be considered limiting, since other embodiments may deviate from the features described in this abstract.

    摘要： A pump having a reciprocating piston/plunger unit adapted to be actuated by a railway wheel rolling over it has a unitary plunger and piston, with the piston double-acting so that when the outlet pressure exceeds a certain value, the plunger remains retracted. An accumulator is provided in fluid communication with the outlet so as to store accumulated hydraulic pressure.
