Abstract: This invention relates to a device for eliminating vibrations of a driver's chair.The device according to the invention is characterized in that it comprises a carrying frame, a cradle located within the carrying frame and carrying the driver's chair. The cradle is provided with a number of rotatably supported pulleys and is carried relative to the carrying frame in that the pulleys contact at least two wires or ropes supported by the carrying frame. One end of the wires is secured resiliently in the carrying frame, and the wires extend transversely to the driving direction for the vehicle, in which the device is to be mounted. A damping arrangement is also provided between the cradle and carrying frame.

Abstract: An automatic locking system is provided for securing a submersible pump to vertical guide wires. The pump is automatically locked to the wires upon lowering of the pump and released upon raising the pump. Stationary cams in the pumping station actuate the locking system. The system assures locking when the pump is lowered and eliminates the need for manual unlocking by the serviceman when raised.

Abstract: Assembly for mounting a cross bar by compression between two opposite walls including two end parts each having a U-shaped yoke to embrace the associated end of the cross bar. One of the end parts has fixed pegs to engage the associated wall, and the other end part has threaded clamping bolts to be screwed against the other wall to clamp the support assembly to the walls by axial compression forces through the cross bar.
