  • Patent number: 5125353
    Abstract: A rupture in a portion of the cargo hold area of a liquid-bulk carrier cargo ship is closed by inserting a flexible, liquid-tight bag through a hatch into the hold, then pumping fluid contained in the hold back into the bag to deploy the bag. The pumping is continued until the bag has deployed far enough to cover the rupture. Such covering prevents further leakage of the cargo out of the hold. The preferred form of the invention includes the use of the ship's pumping system; however, alternative forms of the invention include self-contained units. The preferred form of the bag includes Spectra material.

  • Patent number: 5123368
    Abstract: Rows of closely spaced apertures are installed in a sail to control boundary layer air flow over a sail to laminar flow type by "bleeding" high energy air from the windward or concave side of the sail through the apertures to the convex or leeward side of the sail. The "bleed air" vents the windward boundary layer air through the apertures, gently lifts the leeward or convex side boundary layer off the sail surface; then new laminar boundary layers are formed, on each side of the sail, downwind of the aperture. The increase in air energy adjacent to the sail surface maintains desirable air flow velocity and pressure gradients on the sail that prevents flow separation. The apertures permit large camber of sail contour and high angles of attack without stalling. The air "bleeding" action continuously removes old boundary layer air and creates new laminar boundary air layers on the sail.

  • Patent number: 5121702
    Abstract: A submarine is provided with a large number of individual fins, some of which are arranged to create a "slot" effect between them. The fins are controlled in a way which is dependent on which of them may be in service at a particular time so that manoeuvreability is substantially unaffected by damage to a limited number of them.

  • Patent number: 5119949
    Abstract: A crane vehicle has a movable vehicle body and a pair of outriggers expandable outwardly from opposite sides of the vehicle body in widthwise opposite directions and bearing against the ground to support load weight applied to the vehicle body in stationary state. A column is mounted vertically on the vehicle body and rotatable around its vertical axis. A hydraulic motor effects rotating movement of the column at variable rotation speed in clockwise and counterclockwise directions. A telescopic boom has a free top portion and a bottom portion mounted pivotably at a top portion of the column such that the telescopic boom is angularly movable along a vertical plane containing the vertical axis of the column. The telescopic boom is linearly movable along its axis. A first hydraulic cylinder effects angular movement of the telescopic boom at variable angular speed in upward and downward directions.

  • Patent number: 5119752
    Abstract: The personal motorcraft trailer has a lower shell which is capable of flotation and planing on a body of water. An upper shell has a lip which fits over the edge of the lower shell forming a sealed pod in which gear and supplies may be stored. At least a portion of the upper shell is openably attached by a hinge. The upper shell has two recessed areas in its upper surface, the rear recessed area being deep enough for holding fuel containers and the forward recessed area being relatively shallow and concave to accept gear such as surfboards or skis which are held in place by elastic cords stretched across the gear from hooks on the sides of the upper shell. The trailer is towed behind the motorcraft by a tongue the prongs of which attach at two clips, one on either side of the lower shell. Each prong of the tongue catches under the lip at the front of the trailer to prevent the trailer from digging into the water, causing it to flip.

  • Patent number: 5114025
    Abstract: A swivel for use in a crane has a stationary upper member which is secured to the boom and a lower member which is rotatable relative to the upper member and is connected with the end of the cable. The cable is looped beneath the swivel and the bight of its loop carries a roll which supports the load. A driving unit is provided to positively rotate the lower member of the swivel when the cable portions flanking the roll beneath the swivel tend to cross each other. The driving unit is of the self-locking type or the lower member of the swivel can be braked to prevent a change in its angular position independently of the driving unit. If such independent change of angular position of the lower member is desired, the machine employs a load-responsive clutch which disengages the lower member from the driving unit in the absence of load upon the roll.

  • Patent number: 5114368
    Abstract: A shaft shielding top loader (20) for use in the inlet water channel (12) of a water craft (10) is disclosed. Shaft shielding top loader (20) is configured to divide the incoming water into an upper portion and a lower portion, where the upper portion supplies the top of impeller (13). This is accomplished using an arcuate top loading plate (21) supported by a shaft shielding partition (22). Shaft shielding partition (22) is configured to have a trailing straight edge which is colinearly juxtapositioned with respect to impeller drive shaft (14) to shield impeller drive shaft (14) from the force of the incoming water. Shaft shielding top loader (20) is attached entirely within inlet water channel (12) using a suitable attachment device, such as a screw, at grate connecting adapter plate (24) and shoe plate (26). Shaft shielding top loader (20) insures a continuous water supply to impeller (13) regardless of the craft's orientation to the flow of incoming water.

  • Patent number: 5101750
    Abstract: A tanker is divided into multiple cargo tanks for carrying liquid cargo such as oil. Each tank has a top wall, a bottom wall and side walls. Each tank is provided with a generally horizontal wall that divides the tank into upper and lower zones. The upper zone is located between the horizontal wall and the top wall, while the lower zone is located between the horizontal wall and the bottom wall. The horizontal wall is located near the water line of the tanker and is oil tight so as to eliminate the head pressure of the oil in the tank in the event the lower zone is ruptured.

  • Patent number: 5100351
    Abstract: Several embodiments of water cooled outboard motors embodying an exhaust system that includes at least one expansion chamber contained within the drive shaft housing and that is provided with a coolant jacket. A catalyst is positioned in the exhaust system within the expansion chamber for treating the exhaust gases delivered from the engine to the expansion chamber. The coolant from the cooling jacket is delivered back to the body of water in which the watercraft is operating without flowing into the expansion chamber so as to protect the catalyst from water damage. In some embodiments, plural expansion chambers are incorporaed. In these other embodiments, the expansion chambers are arranged so as to preclude the likelihood of water impinging on the catalyst if it enters through an underwater exhaust gas discharge opening and also the arrangement is such that water will not contact the catalyst when the outboard motor is tilted up to an out of the water condition.
