  • Patent number: 6655866
    Abstract: A mop having a container housing cleaning liquid attached to the mop handle and a new and improved actuation mechanism which employs the use of atmosphere and pneumatics to cause power transmission from the grip area of the mop handle to the fluid actuation area. A mechanism for transmitting discharge power generated by a pump action motion of the handle, similar to loading a shotgun, through the interior of the handle to an actuation diaphragm which causes a valve closing mechanism to open by a vacuum generated from the pump action mechanism, to permit the fluid to be discharged from its container through a nozzle located at the lower portion of the diaphragm while at the same time causing an equal amount of air to fill the fluid container to thereby assure a smooth and even spray of liquid through the nozzle.

  • Patent number: 6613953
    Abstract: A wound treatment device which fits over standard bandages and covers both the wound area itself and major portions of the surrounding area of healthy skin of an extremity such as a leg, arm, or foot. The wound treatment device maintains the wound near normal body temperature (37° C.) by conserving and redistributing the body's own heat energy using a high efficiency thermal insulator to minimize heat loss from the wound and surrounding skin area and a high efficiency thermal conductor for distributing heat from the surrounding skin to the wound area. The wound treatment device avoids potential problems associated with external heat sources and provides for an ideal physiological environment for wound healing. The wound treatment device can be worn by the patient for extended periods of time during their regular daily routine without constant medical supervision. The wound treatment device can also store extra thermal energy generated by physical activity such as walking, cleaning, or bicycling.

  • Patent number: 6568088
    Abstract: A wheel attachment apparatus for a portable circular saw having a circular blade driven by a motor for cutting a workpiece into a cut-off portion and a remaining portion during a cutting process. The wheel attachment apparatus includes a flat bottom plate attached to the circular saw and to be placed above the working piece to support the circular saw during the cutting process, and having a slot opening to allow the circular blade of the circular saw to pass through for cutting the workpiece under the bottom plate. A set of roller wheels is attached to the bottom plate such that when the circular saw is used to cut the workpiece, the set of wheels is brought into contact with the workpiece and elevates the bottom plate so that there is no contact between the bottom plate and the workpiece and instead the wheels are rolling on the workpiece to reduce any friction between the bottom plate and the workpiece and ease the movement of the circular saw during the cutting process.
