  • Patent number: 5482312
    Abstract: A method of making an inflator (10) for an air bag assembly includes the step of providing a first housing member (12) having a recess (22) and a second housing member (14) having a coupling portion (24). One of the housing members, preferably the first housing member (12), includes a container (20). A source of inflation fluid (18) is loaded into the container (20). The second housing member (14) is positioned so that its coupling portion (24) is adjacent to, but outside of, the recess (22). The coupling portion (24) is then mechanically deformed towards the recess (22) to form an integral projection (26) which is tightly received within the recess (22). In this manner, the first housing member (12) is coupled to the second housing member (14) to form a closed chamber (16) containing the source of inflation fluid (18).

  • Patent number: 5476059
    Abstract: A torque enhancer (60, FIG. 1) is provided for an offshore system wherein a turret (18) is rotatably mounted about a vertical axis (22) on a vessel hull and the turret is anchored by catenary chain devices (24), to help minimize rotation of the turret when the vessel weathervanes. The torque enhancer may include a pair of members (80, 82, FIG. 3) with horizontally-spaced inner ends (84, 86) pivotally mounted on the turret and with outer ends (90, 92) coupled to a chain device (24) to transmit horizontal components (E) of tension force that tend to turn the turret to maintain it at its initial rotational orientation with respect to the seafloor. In one system, the arms are rigid beams arranged to form an A-frame, with the outer ends of the arms supporting a guide (100) and with the chain device slidably extending through the guide and attached to the vessel half way between the inner ends of the beams. In another system, a pair of chains (122, 124, FIG.

  • Patent number: 5476054
    Abstract: In order to attain a superior performance of a sailboat (1) under different conditions, e.g., dead calm, average winds, high waves, etc., the invention makes possible that the two longitudinal sides of the hull essentially correspond with the gliding surfaces (11,12) of surfboards. These gliding surfaces are arranged in the shape of a V, may contact one another within the central region (T) of the watercraft (1) and transform into a transition area that forms the bow within the front region by providing additional side walls (15,16).

  • Patent number: 5474008
    Abstract: Eight man rowing shells in lightweight and super heavyweight configurations have an elongated hull with a bow and stern and a smoothly tapered hull surface therebetween. The hull surfaces have particular cross-sections below the waterline at stations spaced along the hull waterline. Other parameters for both super heavyweight and lightweight hulls are provided such as waterline length, entry and exit angles, maximum beam, maximum draft, and metacentric height. In both configurations, the hull itself may be made of a laminate of a fiber composite skin over a core, such as a carbon fiber/honeycomb laminate, or of natural materials such as wood.

  • Patent number: 5474007
    Abstract: A control for a watercraft powered by a jet propulsion unit and having a reverse thrust bucket. In order to permit the operator to easily use the reverse thrust bucket for trim and retardation, a control lever is mounted on the steering handlebar assembly in close relationship to one of the handle grips. A mechanism interconnects the control lever to the reverse thrust bucket and includes a motion amplifying mechanism so that a small degree of movement of the control lever will be transmitted into a large degree of movement of the reverse thrust bucket.

  • Patent number: 5469801
    Abstract: A hydrofoil craft has a hull supported above a water surface by a foil connected to the hull by means of a support arm. In accordance with one form of the invention, the support arm enables the foil to move up and down with respect to the hull in concert with upgusts and downgusts of water surrounding the foil so as to maintain the hull at an approximately constant elevation. In accordance with another form of the invention, the support arm is supported by the hull for pivoting about a longitudinal axis extending in substantially the fore and aft direction of the hull. When rolling forces act on the foil, the support arm can pivot about the axis from a vertical position in response to the rolling forces while enabling the hull to remain substantially level.

  • Patent number: 5468165
    Abstract: A passive anti-clogging device for feeding water into marine jet pumps, which displaces the laminar flow around the trailing surfaces of the intake port, such that foreign debris and grass are precluded from clogging the intake to the jet pump. The primary component of the invention comprises an exclusion plate that is placed in, or immediately below the intake port, and affixed to the breadth of, or becoming a part of, the trailing edge of the intake port, leaving an opening, or slot, between the exclusion plate and ride plate, or bottom of the vessel, which, when at rest, allows the passage of water only from its anterior and lateral extents, thereby excluding the flow of water into the device from directly below or behind the plate. The edge of the exclusion plate angles or curves from a forward central point or apex to a back point at the trailing edge of the intake port, providing a fair surface to resist laminar attachment of debris, marine vegetation or other debris.
