  • Patent number: 7044342
    Abstract: A portable hand held fuel container includes a pour tube, a fill tube spaced from the pour tube, a removable closure cap to close the inlet end to the fill tube, a vent arrangement in the closure cap that permits and prevents exterior air to enter to fill tube to enhance pouring and during pouring inhibits fluid flow through the fill tube in case of overturning of the container, and a vapor seal member connected to the pour tube that is adapted during pouring to simultaneously seal about the fuel inlet to a fuel receiving tank and axially compress to permit deep insertion of the discharge end of the pour tube into the receiving tank.
    Type: Grant

  • Patent number: 6226937
    Abstract: A footing connector has a first hollow leg and a second hollow leg integral therewith. The interiors of the two hollow legs are in fluid communication. The two legs cooperate to form, preferably, a T-shaped connector. The first leg has threading thereon, and, preferably, the second leg has threading thereon and protruberances therein, to enable connection to other elements of a drainage system. The second hollow leg may have end caps integral therewith at the ends thereof. The connector is used in a drainage network to drain water away from the outside of a building and to evacuate unwanted gasses from the inside of a building.

  • Patent number: 5689921
    Abstract: A footing connector and a method for use thereof. The connector is preferably T-shaped and includes integrally formed end caps which may be used to prevent cement or the like from entering into the connector. The connector is used in a drainage network to drain water away form the outside of a building and to evacuate unwanted gasses from the inside of a building.

  • Patent number: 5634311
    Abstract: A device for stabilizing footing drainage conduits while forming the footings including an annular disk and a cylindrical hub extending outwardly from and about the opening. A drain tile or conduit is engaged with the device about the hub while the device is secured to the footing form. The annular disk extends normal to the cylindrical hub. The device is adjusted to abut the form for the building footings. Accordingly, the devices are positioned and attached to the forms. The device provides support and prevents crushing of an end of the conduit when concrete is poured between the form boards when the footings are created. A nub on the cylindrical hub prevents lateral movement of the device when the footing forms are removed. An adjustable drainage tile can also be used. Two sections of conduit are employed for the adjustable drainage tile. One end of one of the sections of conduit has axially extending slits to allow interengagement of the end of the one section of conduit into the second conduit.

  • Patent number: 5560163
    Abstract: A device for interconnecting drainage conduits that have been stabilized while forming building footings includes an annular disk and a cylindrical hub extending outwardly from and about the opening. A stop formed in the hub limits the insertion of the drain tile. A nub on the cylindrical hub prevents lateral movement of the device when the footing forms are removed. Breakaway fasteners are used to hold the device to the footing form. Drainage connectors interconnect with other conduit and connectors connected to other devices to form a network for routing moisture to a desired located.
