Abstract: This invention generally relates to a cable recovery device for use on bo a surface ship. The invention compensates for excessive tensions arising in cables carrying submerged loads which are caused by the swell of the ocean acting on the ship, and controls the tension at which the cable is wound. The invention includes a cable winding drum which is rotationally driven by a variable-speed motor, a loop-shaped cable passageway which circumscribes the drum which forms a loop of cable of varying length, and a means for sensing the length of said cable loop and for automatically controlling the speed of the variable speed motor in response thereto. The loop of cable of varying length compensates for excessive cable tensions resulting from the swell of the ship, and allows the cable to be wound around the drum at a desired uniform tension.

Abstract: This invention relates to a device for handling a submerged load from a s. The submerged load is held by a cable which is attached to a cable recovery drum mounted in an anti-rolling cradle located on a turret affixed to the ship's surface. The device includes a straight beam which carries an appliance for straight-line haulage, for example, pairs of wheels equipped with resilient tires, the device being hinged about a transverse axis.

Abstract: An apparatus provided on a self-propelled underwater device connected to base by a cable. The apparatus comprises an auxiliary propeller disposed at the rear of the device in a support to which is secured the connecting cable and which is connected to the device by a universal joint; the apparatus also includes elements for measuring the forces which the universal joint applies to the device to automatically act on the propeller to offset these forces.
