  • Patent number: 9840310
    Abstract: A seat module suspension system for a high-speed water vessel including a guide assembly for permitting a range of substantially vertical travel of the seat module, an air shock within the guide assembly for resiliently suspending the seat module; and a support assembly extending for impeding athwart movement of a forward projecting portion of the seat module. The support assembly includes a spar pivotally mounted at one end the base of the guide assembly and pivotally mounted at the other end to a mount attached to the underside of the forward projecting portion and configured to permit fore and aft movement, so as to accommodate substantially vertical movement of the seat module. The system also includes a second air shock connected to the support assembly to impede the fore and aft movement and thus support the forward projecting portion of the seat module.

  • Patent number: 9422039
    Abstract: A suspension system for passenger modules or marine platforms used with high-speed boats, the suspension system including a shock absorbing assembly, for supporting the marine platform relative to the vessel. The marine platform is attached to the vessel via an assembly of pivoting spars in which the vessel attachment locations are spaced athwart a greater distance than the marine platform, and the attachment of some spars permits relative fore and aft movement between the spars and the marine platform or the vessel to accommodate pitch. The suspension system may include components for attenuating motion associated with roll.

  • Patent number: 9016226
    Abstract: A suspension system for passenger modules used with high-speed boats, the suspension system including a shock absorbing assembly, for supporting the passenger module relative to the vessel. The passenger module is attached to the vessel via an assembly of pivoting spars in which the vessel attachment locations are spaced athwart a greater distance than the passenger module attachment locations. The suspension system may include means for resisting relative lateral movement (e.g. a panhard rod or a Watt's linkage) and for attenuating motion associated with pitch and roll.

  • Publication number: 20140076787
    Abstract: A method and apparatus in accordance with the present invention comprising a decomposable compound such as hydrogen peroxide as a primary additive to generate bubbles within a fluid medium such as an aqueous slurry of tar sands. The size range of bubbles, density (number per unit volume) of bubbles, and rate of in situ generation of bubbles are controlled by controlling process variables including but not limited to temperature, concentration of decomposable compound, residence time, pressure, viscous shear, ratio of water to solids, pH of the slurry, shape of the separation vessel, and addition of one or more secondary process additives.

  • Patent number: 8628303
    Abstract: A self priming gravity wave water pump, double acting, vertically self adjusting incorporating a submerged column platform as shown in FIG. 4A, the submerged column platform (22) can be tethered (28) or secured by a pivot to a weight (29) or fixed into the water bed (31). The column (22) can be incorporated into an additional submerged water filled column chamber (23), to operate as a hydraulic tidal adjustable column platform. The gravity wave pump (9) is a wave energy converter using wave energy in the form of wave motion to displace a float (2), to lift the pumps reciprocating piston (12) and uses gravity, causing a weight (3) to push a piston down as the wave passes. The pump could pressurise piped water to a head of up to 100 meters or more and could pump pressures in excess of 150 pounds per square inch when adjusted accordingly.

  • Publication number: 20130052042
    Abstract: A wave-powered pumping device for location in a body of water is described. The pumping device includes a submersible cylinder to be anchored to the bed of the body of water, the cylinder defining a bore. An underwater float acts on the cylinder and is arranged to urge the cylinder into an upright orientation in the water. A surface float is arranged to float at, or close enough to, the surface of the body of water in use to move up and down in the body of water in accordance with wave movement and tidal movement. An elongate member depends from the surface float. The elongate member extends telescopically into the bore of the submersible cylinder to define a pumping chamber within the cylinder. The volume of the pumping chamber varies with wave movement in a pumping cycle to draw fluid into the pumping chamber on an upstroke of the elongate member and to pump fluid out of the pumping chamber on a downstroke of the elongate member.

  • Publication number: 20110030601
    Abstract: A suspension system for passenger modules used with high-speed boats, the suspension system including a shock absorbing assembly, for supporting the passenger module relative to the vessel. The passenger module is attached to the vessel via an assembly of pivoting spars. The spars may be configured such that the passenger module moves from an upper at-rest no-load position towards a bottom loaded position, the passenger module tilts. The amount of such tilt may be adjustable. The suspension system may have include means for resisting relative lateral movement (e.g. a panhard rod or a Watts linkage) and an anti-sway device.

  • Patent number: 6672677
    Abstract: A wheel rim protection device for protecting wheel rims when a user is using sprays to clean the tires on a vehicle. The wheel rim protection device includes a dome-shaped cover member having a wall with a main portion, and also having an opening centrally-disposed through the wall, and further having an enlarged rim portion being adapted to detachably attach to a wheel rim on a vehicle, and also having a first arcuate portion being disposed along a portion of an edge forming the opening and which is angled relative to the main portion of the wall to prevent over-spray from coming into contact with the wheel rim.

  • Patent number: 5954597
    Abstract: A tethered ball game apparatus for use by two players. The game includes a net supported between two vertical posts. An upright is attached to one of the posts which supports a horizontal arm. The horizontal arm in turn supports an arm which is at right angles to the net. This arm in turn holds a ball tether support arm to which a tethered ball is held. In use, the ball may be struck over the net and the tether slides along the ball tether support arm. In this way the ball never rolls far from the players so that the game may be played by persons even though they may be physically challenged.

  • Patent number: 5431401
    Abstract: A golf putter is provided with a putter head having a unique configuration. This configuration allows the putter shaft to be disposed in a substantially vertical orientation when the putter head impacts a golf ball. The putter head has a body with a flat, forwardly facing, vertically oriented striking face and a flat, horizontally oriented bottom face disposed substantially normal to the striking face. At the body of the putter a neck is formed that extends upwardly and rises above the level of the striking face of the putter body. The neck projects laterally from the body a distance of at least about one inch and above the level of the bottom face of the body a distance of at least about one inch. The neck of the putter head defines a shaft socket that is substantially perpendicular to the plane of the bottom face of the putter head. The shaft is thereby connected to and seated in the shaft socket.
