  • Publication number: 20050201833
    Abstract: A pipeline is constructed in steep terrain by digging a ditch on the incline, assembling pipe joints together adjacent a top of the incline and then lowering the assembled pipe joints down the incline through the ditch. A wheeled assembly at the lower end of the pipeline carries much of the load and rolls down the ditch as allowed by winch equipment at the top of the incline. Bearing supports are installed periodically in the ditch to support the pipeline, the supports being of a softer material than coatings on the pipe.

  • Patent number: 5190643
    Abstract: A lid assembly for a portable water treatment device of the type including a vessel with an opened upper end and a replaceable filter cartridge adapted to be contained therein. A lid assembly is adapted to be attached to the opened upper end of the vessel above the replaceable filter cartridge and operable to monitor the number of times the water treatment device is used. The lid assembly includes a housing having a central aperture therethrough communicating with the filter cartridge. A gate member is reciprocally movable between a position closing the aperture in the housing and a position opening the aperture in the housing. In the opened position, water to be treated may be poured into the filter cartridge through the aperture. Indicator means are provided and are movable incrementally in response to movement of the gate member. The indicator means move one increment during a cyclic movement of the gate member from the closed position to the opened position and back to the closed position.
