Abstract: A method of retrieving a boat from the water by supporting the boat by two lift sections, each of which has an inflatable bunker and a cradle structure that supports and positions the bunker. The lift sections are connected to a mobile support structure which brings these lift sections to a location near the water into which the boat is to be retrieved. The lift sections are lowered and positioned into the water and the boat is floated into the lift region between them. The lift sections are raised upwardly to carry the boat from the water and to another location over a land surface.

Abstract: A transport apparatus to launch a boat into the water and retrieve the boat from the water. There is an elongate main frame having forward and rear main frame sections pivotally connected to one another along a transverse axis at approximately a mid location along the length. At the forward end of the main frame, there is an operating station and also forward wheels which are capable of turning a full ninety degrees in either direction, and there are at the opposite end rear support wheels which can be raised or lowered. When a boat is being taken out of the water, the apparatus is moved so that its rear end moves into the water, the rear wheels are raised to lower the rear frame section and the two main frame sections are articulated relative to one another to lower the pivot location. In this configuration the boat can be brought onto the rear main frame section, the rear section raised, and the boat carried out of the water.

Abstract: A sealing device for sealing at least two facing surfaces of two adjacent machine elements includes an inflatable sealing tube arranged in a groove in a first surface of a first machine element. The sealing tube can be filled with a medium to which pressure can be applied, and can be inflated by the medium as well as made to rest against a second surface of a second machine element, forming a seal. The ends of the sealing tube are each arranged in an insert piece. The insert pieces are each structured as a sleeve and surround the ends of the sealing tube under elastic pre-stress, forming a seal. The sleeves are each arranged in a recess of the first machine element that extends essentially crosswise to the lengthwise direction of the groove. In the non-pressurized state, the sealing tube and the face of the sleeves that faces the second surface of the second machine element are essentially flush with the first surface of the first machine element.

Abstract: A multiple joint box or distribution sleeve having a tubular sleeve, which has a longitudinal slit with wedge-shaped sealing elements along the slit, and sealing members at both ends of the tubular sleeve characterized by each of the sealing members comprising a pair of rigid disks and at least one elastic circular plate interposed and clamped therebetween, the disks and plate each having a plurality of apertures aligned with each other to form cable inlets with the apertures of the elastic circular plate having a smaller diameter than the aperture of the rigid disks, and each of the disks being provided with a peripheral bevel coacting with each other to form a circular groove for receiving means for forming a peripheral seal.

Abstract: A clamping tool having a bracket arm with a stationary jaw at one end thereof. The bracket arm supports a movable jaw. Each of the jaws have slot openings with grasping means for use in applying tension clamps to cable members. The tool is modified to enable it to function as a cable fitting opening device through the provision of projections attachable to the jaws which projection can be urged towards one another by movement of the movable jaw to urge the projections into contact with projections or recesses of cable fittings to force the cable fittings to open.

Abstract: A cylindrical-shaped cable sleeve, made of a suitable plastic, is formed by mating two semi-circular sleeve portions. With suitable cables inserted through an opening at each end and spliced therein, the two sleeve portions are secured from separation by a suitable clamping device engaging longitudinal mating flanges running on the exterior surface on each side of each half portion. The cable splice is sealed within the sleeve by insertion of a suitable sealant which is prevented from leaking by a series of axially disposed sealing rings interfacing with the cable to form a joint.

Abstract: A sealing member for effecting a gas-tight closure about a cable at an inlet to a hollow cable sleeve fitting. The member is annular in form and is divided on a plane parallel to the cable axis for assembly about the cable after boring a selected passage for the cable through the member. The sealing member has a plurality of radially- and circumferentially-continuous, radially outwardly-extending, longitudinally-spaced ribs engageable via a coating of plastic potting compound with an inner surface of the inlet fitting. The ribs are held in spaced relation by an integral reinforcement member which is spaced radially inwardly of the outer circumference of the ribs. A center portion of the reinforcement member is apertured so that selective boring through of the member to form a cable passage will leave internal radial ribs for bearing against the cable via a second plastic potting compound. Any number and size of cable passages may be provided for.
