    • A mud-saver valve having an independent means for blocking the flow of fluid through the bore of a ball valve. The mud-saver valve has a tubular body having a central through-bore, a rotatable ball having a through-bore, and pressure actuated right and left concave cup members that can rotate about the periphery of said ball regardless of the position of the ball. When the ball is in the open position, the concave cup members may be rotated from an open to a closed position along the outer surface of the ball, thereby blocking the through-bore of the ball and preventing the flow of fluid through such bore.
    • 具有用于阻止流体流过球阀的孔的独立装置的防漏阀。 防漏阀具有管状体,其具有中心通孔,具有通孔的可旋转球,以及压力致动的左右凹杯构件,其能够围绕球的周边旋转,而与球的位置无关 。 当球处于打开位置时,凹杯构件可以沿着球的外表面从打开位置旋转到关闭位置,从而阻挡球的通孔并防止流体流过该孔。

    • Load test apparatus for shipping containers comprising a horizontal beam (200), the beam having pivotal plate assemblies (210) attached to lifting eyes (330) or other feature of a container by cables (130) or similar means, extending from the pivotal plates to the lifting eyes. The pivotal plates rotate about a horizontal pin (430) permitting the pivotal plates to become axially aligned with the cables. The Horizontal beam is forced vertically upward by a plurality of force generating means such as hydraulic cylinders (120). The force of the force generating means is applied through a point common to the longitudinal axis of the horizontal beam and the axis of the horizontal pin, thereby eliminating moment loads within components of the assembly. The opposite vertically downward reaction force is applied to the bottom of the container and simulates the force applied by the weight of the typical contents of the container when it is in use.
    • 用于包括水平梁(200)的运输集装箱的负载测试装置,所述梁具有通过电缆(130)或类似装置从枢转板延伸的附接到提升眼(330)或容器的其他特征的枢转板组件(210) 抬起眼睛。 枢转板围绕水平销(430)旋转,允许枢转板与电缆轴向对准。 水平梁被诸如液压缸(120)的多个力产生装置垂直向上施力。 力产生装置的力通过与水平梁的纵向轴线和水平销的轴线共同的点施加,从而消除了组件的部件内的力矩载荷。 相反的垂直向下的反作用力被施加到容器的底部并且模拟当使用时通过容器的典型内容物的重量施加的力。
