  • Nipple adapter for a standard narrow-mouthed beverage bottle
    Patent number: 6851565
    Abstract: An annular adapter adapts a standard beverage bottle, such as a plastic water bottle, to accommodate the internal threads of a baby's annular nipple cap, which has a nipple inserted therein. Inside the annular adapter is a seal, such as a disc-shaped annular ledge extending in a plane perpendicular to the axis of the adapter, to prevent leakage, when a baby bottle nipple and cap are inserted over the exterior threads of the annular adapter. Liquid flows through the central opening of the annular adapter. The nipple is inserted and the seal engages the bottle of the water bottle, the annular adapter is screwed over a conventional threaded exterior neck of a standard beverage bottle, such as a water bottle.

  • coil spreader for spiral binding machines
    Patent number: 6851907
    Abstract: A binding machine and method for spirally binding a sheaf of papers into a book uses an adjustable speed drive to rotate a flexible plastic spiral element into respective holes in the book. The book has a plurality of holes in a row adjacent one edge of the book to receive the leading edge of the spiral bonding elements. A cylindrically shaped mandrel is spaced apart from a glidable block. The plastic pre-formed spiral binding element is fed onto the mandrel from the distal end thereof, with the leading edge of the binding element facing and spaced apart from the book. A pair of leading edge spreaders, one of which has a guidance groove, engages the plastic spiral to spread its coils just enough to permit it to enter the successive holes of a sheaf to be bound. A trailing spreader at the opposite end insures that the last hole is accommodated with a portion of the spiral coil.

  • Lightweight solid safety swimming pool covers
    Patent number: 6836907
    Abstract: A solid mesh swimming pool cover incorporates a mesh layer that has been successfully used as a porous mesh cover for several years with a thin impermeable base layer. A two-step polymer coating process seals the mesh to produce a solid safety swimming pool cover of unusual light weight and durability with an abrasion resistant bottom layer that has a low coefficient of friction to facilitate easy removal. The base layer is a plastic or resin product, such as a co-polymer resin, and the top layer is a mesh pool cover fabric, such as polypropylene. Ultraviolet (UV) inhibitors added to both coating step materials insure an extended service life. Since the mesh used for the centrally located mesh panels in the drain type solid cover of this invention uses the same mesh as the rest of the non-porous cover, it is more aesthetically pleasing since it blends in with the rest of the cover.

  • Pet grooming mitt with continuous reservoir
    Patent number: 6834619
    Abstract: A mitt grooms and washes a pet such as a dog or cat. The rubber mitt has a built-in reservoir, with discharge ports and massage nibs for efficient pet grooming. Purposeful patterns of densely placed rubber nibs along the longitudinally extending medial area of the palm side engage pet hairs, remove snags and loose hairs, and provide effective massage. The grooming mitt is molded of rubber, and includes a rigid thumb section which provides stability to the mitt, to permit more effective, rapid use and easy discharging of cleaning fluid from the entire surface of the palm side of the mitt.

  • Integral resilient pocket clip and eyeglass frame
    Patent number: 6802604
    Abstract: A clip is integrally formed with or attached to each temple piece of a pair of eyeglass, to hold the eyeglasses to a garment, such as a pocket of a shirt or a belt. The pocket clip member resists torsional bending stresses caused by the constant on and off insertion or removal of the eyeglasses and clip to and from shirt pockets or other attachments. The cantilevered clip is twisted and stressed when the clip holds the eyeglass frame to the shirt pocket in a strong bond. However, the clip is adapted to undergo controlled elastic deformation from an unstressed configuration in response to torsional bending and twisting stress when the clip is inserted or removed from the pocket. The clip is further adapted to resiliently return to the unstressed configuration upon removal of the torsional bending and twisting stress, when fully inserted or removed from the pocket.

  • Micro adjuster for paper punch die
    Patent number: 6799498
    Abstract: A micro adjuster laterally moves a paper punch die. A modified fixed bracket with a larger fine-threaded hole is used to retain a hollow micro adjuster screw which is engaged by the fine threads of the bracket. The retaining screw that attaches to the die now does so by being inserted through the hollow body of the micro adjuster screw and out of a clearance hole at the distal end. Fine lateral adjustments of lateral alignment between the paper to be punched and the die can now be performed by moving the die laterally.

  • Protective cover sleeve for laptop computer screens
    Patent number: 6775128
    Abstract: A hollow sleeve cover covers only the top panel of a laptop computer having the LCD screen, in the folded closed position, thereby separating the finger operable keyboard from the sensitive computer screen. The cover is made of a soft flexible fabric type material, such as ULTRA SUEDE or other non woven suede-like synthetic fabrics, with microfibers, which are impregnated with synthetic resins, shamcloth, moleskin, eyeglass cleaning cloth, made of a weave of nylon and polyester, or other micro polyester materials which do not damage the sensitive LCD screen. Generally rectangular in shape and conforming to the shape of the panel of the laptop computer containing the LCD screen, the cover is open at one bottom edge to permit its deployment over the hinged panel of the laptop computer.

  • Rotating filter feature for wet/dry vacuum cleaner
    Patent number: 6758874
    Abstract: A wet/dry vacuum cleaner includes a debris collection drum having a top opening and a power head covering the top opening of the collection drum, which has an inlet and an outlet. A rotating filter filters dust laden air and is suspended from the power head extending into the collection drum. The power head has an impeller to draw dust laden air, through the inlet, into the collection drum, through the filter, to remove particulate from the dust laden air and to discharge the filtered air through the outlet. The impeller is driver by an electric motor. A stationary blade within the collection drum scrapes an outer surface of the rotating filter, while rotating, to remove accumulated globs of debris from the outer surface of the filter and drop the debris into the collection drum.

  • Hand spray mounts with integral backflow prevention
    Patent number: 6757920
    Abstract: A wall mount provides the normal hose connection for attachment of the hose of a hand-held spray head while integrating a backflow preventer in an aesthetically pleasing unit. The wall mount preferably uses two spring-biased check valves with an integral air inlet and check valve to form redundant backflow prevention as well as an active vacuum breaker which substitutes ambient air for dirty water in the case of vacuum build-up. The wall mount includes a seal and locking technique which permits exact set-up of the orientation and wall fit of the unit with simple tools. An alternate embodiment of the wall mount also integrates the hook which holds the handle of the hand-held spray head.

  • External flue heat exchangers
    Patent number: 6749014
    Abstract: A heat exchanger is mounted external to a section of flue pipe or is an integral part of a section of flue pipe. The heat exchanger preheats a domestic hot water supply and boosts the return water temperature prior to reentry to the furnace coil. The heat exchanger reduces fuel use, pollution and wear of the furnace and burner. A typical heat exchanger installation includes an oil or gas burner located on a furnace or boiler having a flue pipe leading to a gaseous outlet, such as a masonry chimney. A short vertical flue section leads to a draft-regulating damper. The flue heat exchanger may be a coil of tubing wrapped around flue section, such that the tubing picks up heat from the heated flue gasses. Preheated water exits from the heat exchanger.
