  • Patent number: 6039185
    Abstract: A thin flexible sheet of PETG or similar plastic has a disk shaped body with a number of radially protruding petals. The outer perimeter of one side of the inserter is coated with a pressure sensitive adhesive. A hearing aid battery with its connected selectively-gas-permeable tab is adhered to each of the inserter petals. Each petal has a small through hole positioned in alignment with the vent hole on the battery, which permits exchange of gases through the semipermeable tab. A battery is inserted into a hearing aid while attached to the inserter by gripping the inserter between the thumb and forefinger, and positioning the battery into an adjacent hearing aid battery compartment and then separated from the inserter by a sliding or wiping motion. The inserter is retained in a container fixed by removable side strips to a backing card.

  • Patent number: 6035966
    Abstract: Adjustable upper straps extend from the four corners of a collapsible seat assembly and terminate at a central O-ring. A groin strap extends from the central ring to a portion of the seat assembly. A tree ascender strap is also connected to the central ring, and has a latchable hook which can be used to encircle the trunk of a tree and secure the climber as he climbs. A back strap and shoulder strap extend from the central ring and help to restrain a hunter within the assembly both while climbing and while in an elevated position in the tree. A main lead securing strap extends from an extension strap connected to the central ring and has a buckle which allows it to be secured around a tree above the head of the hunter. The main lead securing strap is looped through itself in such a way that the strap chokes the tree trunk within itself to prevent slipping on trees with smooth bark.

  • Patent number: 6029885
    Abstract: A container blank has a bottom panel with outwardly extending inner and outer end panels which fold up to form double thickness end walls. Two opposed parallel side panels have glue tabs which are affixed to the outer end panels. Each glue tab has a 45-degree angle fold line which allows the side panels to be folded to overlie the bottom panel during shipping. In a covered box where the height of the box h measured vertically exceeds one quarter the length of the end panel and approaches one half the length of the end panels, there is not space available to receive the cover front flap tab within a pocket defined between the end wall and an adhesively attached glue tab, if the glue tabs in front and in back are of equal size. To accommodate the enlarged cover front flap tabs, the front glue tabs may extend a greater distance along the end panels than the rear glue tabs. The rear glue tabs are less than half the length of the outer end panels, and do not extend frontwardly beyond the glue tab fold line.

  • Patent number: 6027189
    Abstract: A molded plastic housing is mounted within an opening of predetermined size in the front wall of a cabinet beneath a counter top. Evenly spaced parallel grooves in the top wall of the housing receive dispensing modules constructed with peripheral pairs of upwardly protruding fins which are spaced distances which are multiples of the spacing between the parallel grooves. Each module, be it a napkin dispenser, a straw or stir stick dispenser, other box-like unit, may be inserted at any location within the housing. The volume within a single housing may thus be occupied by many different dispensing modules, or by multiple modules of the same type. Differentiated dispensing cavities may be formed by one or more dividers having a single upwardly extending fin which engages within a housing groove, and a lower base which engages the housing lower wall. A transparent face plate has two rearwardly extending ears which are flexible to extend into the housing on either side of the dispensing modules.

  • Patent number: 6022061
    Abstract: A thermoformed thermoplastic truck bedliner has at least one pair of under-cut load restraint pockets formed by portions of opposed bedliner sidewalls. The pockets are recessed from the sidewall so that a load restraining member such as a 2.times.4 beam may be pressed downwardly to be snapped into engagement with the pockets. The pockets support the boards in a horizontal orientation, with the wide dimension of the board extending from front to back within the liner to give greater board stiffness against loads shifting from front to back. The pockets may be formed in either under the rail bedliners or in over the rail bedliners. In an alternative embodiment, each under-cut pocket is formed in a cross shape such that a board may be positioned horizontally or vertically.

  • Patent number: 6017075
    Abstract: A thermoformed thermoplastic truck bedliner has a bottom wall with parallel front-to-back ribs which overlies the floor of a truck cargo bed. Two side walls extend upwardly on opposite sides of the bottom wall and are joined at a front wall. Ribs of a normal height define the load support surface of the bedliner bottom wall, while regions of parallel ribs which are lower in height than the normal ribs define cargo containment regions. The intersection of the reduced height ribs with the normal height ribs defines ridges which restrain escape of cargo in the front-to-back direction, while the bedliner side walls and elevated height protrusions on normal height ribs adjacent to the cargo containment regions restrain side-to-side displacement of the cargo.

  • Patent number: 6010321
    Abstract: A gear motor has a hydraulic oil drain path through bearings which support the spindle and mounted mower blade. The drain path is through two plain bearings and two opposed thrust bearings to a low pressure port located adjacent to the spindle shaft seal. A drain from the low pressure port through one of the hydraulic motor shafts leads to the case drain. A check valve prevents fluid from leaking through the drain should the spindle shaft seal fail. The plain bearings and thrust bearings have a press fit insert in the shape of a cylinder with a planar lip. The cylinder portion of the insert forms the plain bearing and the planar lip of the insert forms the thrust bearings. The bearing insert cylindrical surfaces have two helical grooves which extend across the cylindrical surface to conduct lubricating oil through the plain bearings. The grooves in the plain bearings communicate with similar grooves in the thrust bearings.

  • Patent number: 5993022
    Abstract: A flashlight has a center pivot mechanical connection between a plastic battery housing and a rotatable plastic turret, permitting free rotation of the turret. A lamp housing is pivotable within the turret about an axis perpendicular to the center pivot. Electrical connection between the lamp within the lamp housing, and the batteries within the battery housing is provided by two pairs of ring and point contacts mounted to the turret and the battery housing, and by ring contacts connected to the lamp housing surrounding the pivot axis of the lamp housing which engage with a point contact and ring contact in the turret. The light may thus be pointed in any direction in the hemisphere above the battery housing. A snap ring securely retains the turret to the battery housing while permitting free rotation about the rigid center pivot which does not provide electrical connection.

  • Patent number: 5975879
    Abstract: Multiple legs elevate a central ring bearing, to which a ring-shaped rotatable plastic sheet support carousel is mounted. The carousel is fitted with a ring gear which engages with a drive system to position the carousel and the thermoplastic sheets supported from it. A multi-post vertical press is positioned with two posts extending upwardly interior to the ring bearing, and two posts extending upwardly exterior to the ring bearing. The ring bearing thus extends through the press, allowing the carousel to supply and remove plastic sheets to and from the press. An upper platen and a lower platen are mounted for vertical displacement to the posts, thereby ensuring a high degree of parallelism between the molds mounted to the platens, and accurate twin-sheet thermoforming.
