    • A flexible hose take-up assembly for automatically retracting a flexible fluid dispensing hose is disclosed. A cabinet having an interior chamber at least partially filled with a damping liquid houses a pulley assembly and a pair of counterweights used to control flexible hose pay out and retraction. A flexible hose of the type used in automotive service centers is attached to the ends of the cable of the pulley assembly such that the hose is stored adjacent the exterior of the cabinet when in the stored position. The pulley assembly permits the movement of the counterweights carried by the pulley assembly, the counterweights being at least partially immersed in the damping liquid, in a first direction away from a home position within the cabinet in response to the movement of the flexible hose from its stored position to one of its fluid dispensing positions, and permits the gravitational movement of the counterweights through the liquid in a second direction back toward the home position in response to the release of the hose from its fluid dispensing position. The hydraulic damping imposed on the counterweights by the liquid provides a uniformly controlled rate of retraction and substantially eliminates hose snap-back during movement in the second direction.
    • 公开了一种用于自动缩回柔性流体分配软管的柔性软管卷取组件。 具有至少部分地填充有阻尼液体的内部室的柜体容纳滑轮组件和用于控制柔性软管的支出和缩回的一对配重。 用于汽车维修中心的柔性软管连接到滑轮组件的电缆的端部,使得当处于存储位置时,软管邻近机柜的外部被存放。 滑轮组件允许由皮带轮组件承载的配重的运动,配重至少部分地浸入阻尼液体中,以便响应于柔性软管从其内部的运动而远离机壳内的原始位置的第一方向 存储位置到其流体分配位置之一,并且响应于软管从其流体分配位置的释放,允许配重件在第二方向上通过液体的重力运动返回到原始位置。 通过液体施加在配重上的液压阻尼提供均匀控制的回缩速率,并且在第二方向移动期间基本上消除了软管卡扣。

    • A device for changing the location of fuel elements and control rods in a core reactor with a guiding mast which is mounted on a movable working platform for rotation about a vertical axis and which is provided with a gripping body for grasping the fuel elements and control rods, said gripping body being suspended on a lifting mechanism and being displaceable in vertical direction within the guiding mast while being prevented from rotating relative to the guiding mast. The device furthermore comprises winding means for storing supply lines which are introduced at the top into the guiding mast and the gripper body.The device also includes power operated means for actuating the lifting mechanism. The winding means and lifting mechanism rotate with the mast and are so arranged in the mast that any water dripping therefrom runs down the inside of the mast. Supply conduits leading to the mast are connected thereby by slack loops which permit 360.degree. of rotation of the mast.
