  • Patent number: 6482370
    Abstract: The present invention uses ozonated water as a cleaning agent to eliminate bacterial and biofilm in dental water lines instead of using cleaning solutions. The ozonated water disinfects/sterilizes and cleans quickly and without leaving any residue, because the ozone quickly converts to oxygen and goes into the atmosphere. Thus, little or no rinsing is required after using the ozonated water to clean a machine or device. More particularly, the present invention utilizes an apparatus for disinfecting water to make it virtually microbe-free and maintaining it in a continuous microbe-free condition for use at a center for dental applications. Water is ozonated and provided for disinfecting water lines during a cleaning cycle and stored in a pressurized reservoir for use in a variety of dental instruments such as drills, syringes and an expectoration bowl.

  • Patent number: 6464278
    Abstract: A vehicle tail gate mounted on sliding pivots wherein the channel portion of the sliding pivots are on the vehicle and have the initial entry portion thereof sloping downwardly in a direction toward the front end of the vehicle. The tail gate has two spaced apart pins (each preferably with a roller thereon) on each of opposite edges thereof and all four slide in the channels with one pair being on the sloping portion of the track thus by gravity biasing the tail gate into its retracted position in a storage compartment provided therefor under a floor of the vehicle.

  • Patent number: 6389852
    Abstract: A water supply safety valve kit for an appliance in which the kit includes an individual solenoid actuated normally closed valve unit for each water supply line to the appliance and a control unit that plugs into a conventional electrical female household outlet. The control unit has a first outlet at the household line voltage and into which the power cord of the appliance plugs and a second lower voltage outlet responsive to current flow to the first outlet. A count down timer circuit and a low voltage output are activated by the current flow to the first outlet and lines connect that low voltage output to the solenoid valve unit to open the same. The count down timer terminates the low voltage output after a preselected time period.

  • Patent number: 6389930
    Abstract: A tool, for use in turning the screw on a hose clamp, in which a shaft is slidably and rotatably mounted on an elongate slender body member and resiliently biased toward an abutment on the body member to grasp there between the screw on the hose clamp. The shaft has a tool head end to drivingly engage the screw head and at the other end a handle or socket for use in turning the shaft. The abutment on the body has a recess to receive therein the free outer end of the hose clamp screw. This recess and the socket on the drive head end maintain the screw and drive in axial alignment during use. A lug on the body member projects toward and terminates proximate a leading end portion of the shaft turning handle. The lug and its proximity to the handle make it easy to manipulate the tool using one hand.

  • Patent number: 6370727
    Abstract: An open frame for supporting a venetian blind facilitating washing the blind. The frame has a pair of spaced apart elongate side members each with a face plate and an end plate and are interconnected by a cross member. The cross member adjustably positions the spacing of the side members to suit blinds of various widths. A pair of saddles are adjustably mounted on the side members for releasibly supporting the top rail of the venetian blind. Pins through the frame are insertable into opposed ends of the bottom rail of the venetian blind.

  • Patent number: 6322120
    Abstract: A frame having upper and lower longitudinal frame members supports pairs of pivotally connected holding arms having curved “J-shaped” distal ends and curved blades mounted thereinbetween. Latch arms pivotally connect to one another on one end and to a short upper frame member and a short lower frame member of the longitudinal frame members support a disassemble cylindrical cam latch and lock assembly mounted onto the upper latch arm. A travel pin moves up and down within a predetermined channel or groove formed in a solid one piece cast cylindrical bushing and rotates in a predetermined pattern to simultaneously rotate and move a locking dog and a wedge shaped plunger extending downwardly therefrom up and down and in for cooperative engagement with a slot or keyhole formed in the lower latch arm thereby engaging or disengaging the “J-shaped” holding arms.
