    • A chain-drive transmission including two sets of a plurality of sprockets, each set rotatably mounted on a rotatable shaft. Sprockets on each shaft are paired with a corresponding sprocket on the other shaft and are joined by the drive chain. The diameters of each pair of sprockets are selectively predetermined so as to provide a desired speed range for the chain-drive transmission. A selector and interlock mechanism is also provided so as to suitably select and interlock each preselected sprocket with its respective shaft thereby transmitting torque between the two rotatable shafts through the chain.
    • 链条驱动变速器,其包括两组多个链轮,每组链轮可旋转地安装在可旋转的轴上。 每个轴上的链轮与另一个轴上的相应链轮配对,并通过驱动链连接。 选择性地预定每对链轮的直径,以便为链传动传动提供期望的速度范围。 还提供选择器和联锁机构,以便适当地选择并互锁每个预选的链轮及其相应的轴,从而通过链条在两个可旋转轴之间传递扭矩。

    • A pipe hanger/snubber for supporting and/or protecting high-pressure piping and the like against damage by seismic, vibrational, and thermal shocks to the mechanical integrity of the piping system. The apparatus includes a sealed snubber cylinder containing a non-Newtonian fluid as the hydraulic fluid medium. A working shaft extends completely through the snubber cylinder. A shaft-mounted, perforate load nozzle is moved longitudinally through the non-Newtonian fluid in the snubber cylinder to thereby dissipate the shock forces. Shaft-engaging seals at each end of the snubber cylinder inhibit leakage of the non-Newtonian fluid from the snubber cylinder. Selectively, reservoir apparatus containing non-Newtonian fluid are provided adjacent at least one seal to compensate for leakage, if any, of the non-Newtonian fluid through the seal. The reservoir apparatus are provided with leakproof closures and, selectively, compression/expansion apparatus to compensate for volume changes imposed on the non-Newtonian fluid in the reservoir apparatus.
    • 用于支撑和/或保护高压管道等的管悬挂器/缓冲器,以防止由于地震,振动和热冲击而损坏管道系统的机械完整性。 该装置包括一个包含非牛顿流体作为液压流体介质的密封缓冲缸。 工作轴完全延伸穿过缓冲缸。 轴安装的穿孔装载喷嘴纵向移动通过缓冲缸中的非牛顿流体,从而消散冲击力。 缓冲缸两端的轴接合密封件可防止非牛顿流体从缓冲缸泄漏。 选择地,包含非牛顿流体的储存装置设置在至少一个密封件附近,以补偿通过密封件的非牛顿流体的泄漏(如果有的话)。 储存装置设置有防漏盖和选择性地压缩/膨胀装置,以补偿施加在储存装置中的非牛顿流体的体积变化。
