  • Patent number: 9308608
    Abstract: A plunger installation and retrieval tool that incorporates a magnet which magnetically supports a fluid lift plunger during insertion into or retrieval from a lubricator on a natural gas wellhead. The magnet is housed in a magnet holder suspended from an elongate hanger member the upper end of which is connect to a hanger support. An actuation rod slidably extends through the hanger support and through bores in the magnet and magnet holder, such that a downward force applied to the actuating rod will cause the lower end of the actuation rod to project below the magnet and break its magnetic bond with the plunger, thus releasing the plunger from the tool. The tool may be provided with a cylindrical skirt fitting closely around the upper end of the plunger to prevent laterally leading that could break the magnetic bond during plunger insertion and retrieval.

  • Patent number: 7322563
    Abstract: Underground water valves having square operating nuts, such as but not limited to critical water valves which control different pressure zones or different demand areas, are secured by a shielding cap, each of which have a recess that receives a valve operating nut and a cylindrical projection which frustrates attempts to rotate the operating nut. When an authorized person decides to open or close one of the valves, the shielding cap is retrieved from the operating nut by a retrieving head which has the socket defined by a frustoconical recess. Within the recess are a pair of opposed pins which seat in J-shaped slots in the frustoconical projection. Upon rotating the retrieving head, the pins move into alignment with open ends of the J-shaped slots, down shank portions of the slots and abut closed ends of the slots so that the shielding cap may be pulled from the valve operating nut and withdrawn through the valve operating box.

  • Patent number: 7117883
    Abstract: A self-aligning curb box assembly is provided. The curb box includes a cylindrical conduit extending from the ground surface downwardly and has a detachable cover at its upper, surface end. The conduit has an inverted “U” shaped passageway formed at its lower end through which a generally horizontally oriented supply line, such as for water or gas, passes. The supply line has a valve body and an “open-to-shut” valve cock located in the line positioned within the passageway at the lower end of the curb box, the valve cock extending upwardly. The assembly includes a positioning insert placed within the curb box at its lower end thereof. The insert limits lateral movement of the valve body in any direction throughout 360° in the plane about the valve when the insert is installed.

  • Patent number: 7094000
    Abstract: A joint suitable for construction castings having a frame and a lid or cover, such as manholes, grates, trench drains, hatches and the like, and construction castings incorporating the same. No tools are necessary to separate the joint. An enlarged head located on a cover fits into a socket located on a frame or adjacent lid. To separate the head from the socket, the lid is lifted to a substantially vertical position and turned about ninety degrees. The lid can then be lifted away from the socket. When the joint is used in manhole or hatch assemblies, a latch may be used to hold the cover open and the cover may be opened and closed with a lever.

  • Patent number: 7004677
    Abstract: A valve containment assembly for an irrigation system may have a first side wall unit, a grate, a second side wall unit, and a lid. The first side wall unit may be disposed on the floor of a hole. The grate may be positioned in the first side wall unit to support a manifold. The second side wall unit rests on the first side wall unit to cover the manifold and the lid may be disposed on top of the side wall unit. The first side wall unit and the grate elevate the manifold above the floor of the hole to reduce interference of soil and water with the manifold. Additional side wall units may be used to provide additional height. Any of the side wall units may have frangible portions that break away to permit passage of conduits into the valve containment assembly.

  • Patent number: 6820646
    Abstract: The invention concerns an installation for measuring and displaying protected against risks of being frozen, comprising a fluid metering assembly (1) connected to a fluid supply pipe (2) and a fluid outlet pipe (3). Said fluid metering assembly (1) is mounted in an inspection window (4) below the frost line, said pipes extending in a trench produced in the ground (13) and connected to the inspection window (4). The metering assembly (1) is removable with or without interrupting pressurised fluid. A metering plate (8) retains flexible junction means (9, 10) connecting the intake and the outlet pipes (2, 3) to the metering assembly (1). The installation comprising the fluid metering assembly (1) is useful for maintaining protected against frost and accessible standard valves and fittings, in particular straight or coaxial meters (1).

  • Patent number: 6749080
    Abstract: An adjustable underground utility housing with a lid for access from above ground is disclosed and comprises a housing formed with upstanding wall portions defining a cavity having an upper opening to support a lid and a bottom opening. The housing has utility piping inlet and outlet openings through which the piping enters and exits the housing for servicing a facility. The openings each have flexible closures for preventing dirt from entering the openings into the cavity of the housing. The closures are sufficiently flexible for sliding down over the utility piping yet sufficiently resilient to prevent the dirt from entering the housing cavity. The closures can be formed with overlapping horizontally oriented bristles, with a sheet of rubberized material having a centrally located vertical slit, or with this same sheet of rubberized material with the addition of horizontal slits to form reinforced stiffened fingers.
