  • Patent number: 6865833
    Abstract: A visual display including a container, liquidous fluid within the container, a source of gaseous fluid communicating with the liquidous fluid, and at least one binary bubble formed within the liquidous fluid in response to gaseous fluid entering the liquidous fluid. The liquidous fluid is preferably a polymer in water solution or a polymer in mineral oil or silicon oil solution. The binary bubble has two bulbous portions in fluid communication with each other through a neck. The binary bubbles may link together in a chain extending from the bottom of the container to the top of the liquidous fluid. In other constructions, the binary bubbles float up through the liquidous fluid and collapse into a large individual bubble. The display may also include a light emitting source and a filter for selectively changing the color of light emitted into the container.

  • Patent number: 6857380
    Abstract: A retractable bowsprit for a sailboat is suitable for use with an asymmetrical spinnaker. A support element and a bowsprit positioner such as a track mounted within a hull of a sailboat allow the bowsprit to assume either an extended or retracted position. The bowsprit positioner is mounted to the bottom of the hull. The support element is positioned forward of and above a forward position of the positioner. The bowsprit can slide through the support element, to allow an aft end of the bowsprit to be attached to the positioner's forward point in the extended position. When the bowsprit is so positioned, the geometry causes the bowsprit to rotate, placing a forward end thereof substantially further above the waterline than is the deck, allowing the crew a view beneath an asymmetrical spinnaker attached to the bowsprit forward end.

  • Patent number: 6846212
    Abstract: In fuel supply system for an engine in which a discharge port in a fuel pump driven by the engine to draw up fuel in a fuel tank is connected to an inlet port which is provided in a fuel reservoir and which is controlled in opening and closing by a float valve so that the fuel in the fuel reservoir is supplied to the engine, a second discharge port is provided in the fuel pump, and a second inlet port without a float valve is provided in the fuel reservoir. The second discharge port and the second inlet port are connected to each other through a control valve opened during starting of the engine. Thus, when the engine is started, fuel vapor generated in a pump chamber in the fuel pump can be discharged to the fuel reservoir having an air vent, to normalize the function of the fuel pump, leading to an enhancement in hot startability of the engine.

  • Patent number: 6837760
    Abstract: The present invention is directed to a method of altering the pitch of a propeller through localized bending of its blades. To alter the propeller's pitch the camber of at least one of its blades is changed by bending a portion of a trailing edge, a leading edge, or both edges relative to a remainder of the blade. A bent portion can be located away from a tip of the blade at a distance that is less than or substantially equal to 60% of a radius of the blade, and bending preferably commences at a distance in from an edge of a blade of up to 50% of a section width of the blade. The maximum preferable change in pitch at any location on the radius due to bending is 30%.
