  • Patent number: 6025559
    Abstract: A twist-on spring connector includes a multi-piece connector assembly in which a wire or wire bundle is first joined together and subsequently encapsulated into a moisture-resistant sealant. A shell has an open end, a closed end, spaced apart landings including shoulders adjacent the open end and a sealant material in the closed end. A spring holder has sealant passages and spaced apart flanges. The spring holder is mounted in the shell so that the flanges engage the landings. The flanges are limited from movement in a first direction by the shoulders during wire insertion and are movable in a second direction to channels between the landings permitting the spring holder to move toward the closed end of the shell and receive sealant in the sealant passages. An end cap is mounted in the open end of the shell so that the spring holder is retained in the shell and the flanges of the spring holder are movable relative to the landings.

  • Patent number: 5520234
    Abstract: An assembly for decorating the top of a window. Generally, the assembly includes a pair of linear members with side panels attached at each end. The side panels have integral mounting posts being received by slots in the linear members. Optionally, the linear members are attached to the side panels with discrete couplings that are received by both the side panels and the linear members. A fabric covering is applied over the assembly and attached to the rear of the assembly by use of glue. Optionally, the fabric covering is attached via a mechanical fastening system located on the rear of the assembly. Mounting brackets are used to secure the window top decorating assembly directly to the wall surrounding the window or, if a window covering unit is in place, to the headrail of the window covering unit.

  • Patent number: 5333408
    Abstract: A portable container having a hinged lid and an electric lighting assembly mounted to the body of the container. The lighting assembly is located external to the interior storage compartment of the container when the lid is in the closed position. The lighting assembly includes an electric lamp for illuminating the interior of the container when the lid is in the open position and an electric lamp for illuminating the path of the person carrying the container when the lid is in the closed position.

  • Patent number: 5297487
    Abstract: An apparatus that contains inks and other substances of similar viscous within the usable area of a screen printing frames assembly. A structural assembly defining the enclosed area in which the ink is to be contained fits within the perimeter of the frame. Incorporated into the structural assembly is a resilient sealing edge which ensures that the ink is contained within the area defined by the apparatus. Furthermore, a substantially rigid retaining mechanism is incorporated into the apparatus for positive assurance that the position of the apparatus relative to the screen printing frame assembly is maintained constant. In a preferred embodiment, the retaining mechanism consists of a series of rigid retaining arms which are secured to the frame using threaded fasteners.

  • Patent number: 5224418
    Abstract: An apparatus that contains inks and other substances of similar viscous within the useable area of a screen printing frames assembly. A structural assembly defining the enclosed area in which the ink is to be contained fits within the perimeter of the frame. Incorporated into the apparatus is a resilient sealing edge that ensures that the ink is contained within the area defined by the apparatus. Furthermore, a flexible retaining member may be incorporated into the apparatus for positive assurance that the position of the apparatus relative to the screen printing frame assembly is maintained constant. The apparatus is quickly and easily installed by positioning it on top of the frame, applying pressure on the top of two opposing sides of the structural assembly, and pressing it firmly against the screen and is disengaged by applying an upward force under one or more of the corners of the structural assembly until it separates from the screen printing frame assembly.
