  • Publication number: 20080257245
    Abstract: As Aileron (fin) is to airplanes and aqualeron is to ships, a device with fins position on both sides of the keel in a horizontal position where a set of gears controls the fin on one side in a downward arc and the other side in an upward arc providing a controlled below water force to maintain any arc of travel on a sail boat, or as a hydrofoil. A set of fins positioned on the bottom of a sailboat eliminating the keel. A set of fins positioned at the bow of a motor boat providing a downward force of the bow. A set of fins on either side of the stem of a power boat, when activated, swing out directing water to the rear of the boat filling the cavity created by the boat to eliminate the wake. A set of fins on both sides when opened to a tube allowing a force of water to enter and empty at the rear of the boat filling the cavity with instant water thereby controlling a wake free operation.

  • Patent number: 5618420
    Abstract: Separate devices for removing oil from water where no tank or vessel is required next to the skimmer since the scraper is at an angle from the horizon designed to flow oil away from the skimmer into a tube to a pump and can be used in confined areas, shallow water or for industrial use to remove oil. Skimmers are designed to retrieve oil in any type of weather conditions. The containment boom is made of a flexible material rolled in a tight bundle having 2 compartments where water and air are pumped, having relief valves with flexing joints to insure containments during high waves. The oil is pumped into sacks which are stored in canisters on the sides of the tanker for quick release.

  • Patent number: 5224500
    Abstract: A flosser which holds the floss between two (2) unequal length prongs located in the head piece. The floss moves back and forth by a motor. When the floss is placed between the teeth and laterally moved forty-five degrees, the floss will clean between and the opposite sides of the teeth. When removed and rotated 180 degrees and placed between the same teeth, it will now clean the opposite sides of the same teeth, resulting in cleaning the four sides of the teeth. The head is detachable so that a separate round toothbrush with a guard on half of it will be able to brush in between the teeth. The top teeth are cleaned with the motor operating counterclockwise, the bottom teeth cleaned with the motor operating clockwise. However, due to its reversability, the motor may be operated in either direction as desired.
