摘要： An improved means of attaching a fore stock to a break action firearm provides for convenient adjustment to compensate for dimensional variations caused by wear, or occuring during manufacture of the various firearm components, and allows the user to adjust the tightness of the action. The stock is screwed to a wedge member riding on a cammed lug carried by the firearm barrel, such that tightening of the screw causes the stock to be cammed against the receiver hinge.

摘要： The present invention is directed to an improved blower system particularly useful for vehicles wherein the one or more fans, squirrel cage blowers or the like are driven by a hydraulic motor which is powered directly from the hydraulic system of the vehicle. Thus, the blower system of the present invention may draw on such hydraulic power without presenting any substantial drain on the hydraulic system or on the vehicle engine. For equal physical size motors, the hydraulic motor typically has an increased output capacity over conventional DC electric motors previously employed in such blower systems. Moreover, the hydraulic motor is continuously lubricated by hydraulic fluid flowing therethrough so that there is minimal wearing of the parts thereof with the end result that the life expectancy will ordinarily equal or exceed that normally expected for a typical vehicle.
摘要翻译：本发明涉及一种特别适用于车辆的改进的鼓风机系统，其中一个或多个风扇，鼠笼式鼓风机等由直接从车辆的液压系统供电的液压马达驱动。因此，本发明的鼓风机系统可以利用这种液压动力，而不会在液压系统或车辆发动机上出现任何实质的排水。对于相同物理尺寸的电动机，液压马达通常比之前在这种鼓风机系统中使用的常规直流电动机具有增加的输出能力。此外，液压马达由流过其中的液压流体持续润滑，使得其部件的磨损最小，最终结果是通常等于或超过通常对于典型车辆通常预期的寿命。

摘要： An exercise device has a cord contained in a housing with a handle on the cord to pull it out of the housing. Resistance is developed by sliding friction between the cord and the housing and between the cord and a spool in the housing. The device has independent adjustment for controlling the friction between the cord and the housing and the spool friction. A recoil wheel retracts the cord.
摘要翻译：运动装置具有包含在壳体中的绳索，绳索上的把手将其拉出壳体。电阻通过电缆和壳体之间以及电缆和壳体中的线轴之间的摩擦而产生。该装置具有独立的调整，用于控制绳索和壳体之间的摩擦以及滑阀的摩擦。反冲轮缩回电线。
