Abstract: An apparatus for anchoring a floating off-shore unit or other type of floating vessel, comprising a rotatably mounted chain sprocket wheel (3) having a chain (3a) secured on its outer periphery, The wheel (3) being arranged to be rotated by reciprocating movement of at least two hydraulic cylinders (1, 2). Each of the cylinders (1, 2) is provided with a locking arm (6, 7) for releasably and mechanically engaging a portion of the wheel (3) in order to rotate the wheel (3) during movement of the respective cylinders (1, 2). Also described is a chain stopper comprising at least four blocks (8) that are hinged at their first ends and at their second ends have a surface that is adapted to engage a chain link The blocks (8) are mounted in opposite pairs.

Abstract: Training apparatus for physical exercise, preventive exercise and rehabilitation of injuries and increased balance, the apparatus designed as a stationary bicycle, similar to ergometer bikes or spinning bikes. The apparatus consist of a first lower stable frame configured to be supported on a floor and a second upper frame tiltable relative to the lower frame. The upper frame has an adjustable tilt movement relative the lower frame crosswise the flywheel's revolving motion. A steering gear is guided through the upper frame where a prolonged part of the steering gear is in contact with the floor, the part having a wheel suspension like design, consisting of barlinks, dampers, springs and wheels. Stabilizing of the upper frame is done by movement of the steering gear.
