Abstract: A closet carrier assembly has a carrier body assembly having at least one inlet for receiving waste and at least one outlet for communicating waste to a waste plumbing. The at least one inlet has internal threads and an outward facing surface substantially orthogonal to a longitudinal axis of the inlet. A tubular coupling is adapted to extend between the carrier body and the water closet. The tubular coupling has external threads thereon that threadingly engage the internal threads of the carrier body assembly and a flange member thereon that extends orthogonally to a longitudinal axis of the tubular coupling and resides adjacent the outward facing surface of the carrier body assembly. A deformable seal is compressed between the outward facing surface of the carrier body assembly and the flange member of the tubular coupling to form a water tight seal between the carrier body assembly and the tubular coupling.

Abstract: A vertically adjustable valve box for providing access to underground valves includes a first member having a tubular section with a bell and a peripheral flange disposed at a distal end. A second member has a tubular section with a bell and a flange disposed at a distal end. A second peripheral flange is disposed on the exterior surface of the second member approximately six inches below the face of first flange. The tubular section of the second member is telescoped over the tubular section of the first member, wherein the respective bells and flanges are disposed on opposite ends of the assembly and the central longitudinal axis of each is vertical and substantially in alignment. An O-ring gasket is positioned circumferentially around the exterior of the tubular section of the first member and prevents the second member from telescoping downward on first member past a desired insertion position.

Abstract: A vertically adjustable valve box for providing access to underground valves includes a first member having a tubular section with a bell and a peripheral flange disposed at a distal end, wherein the central longitudinal axis of the first member is oriented vertically. The invention further includes a second member having a tubular section with a bell and a flange disposed at a distal end. The tubular section of the second member is telescoped over the tubular section of the first member, wherein the respective bells and flanges are disposed on opposite ends of the assembly and the central longitudinal axis of each is vertical and substantially in alignment.An O-ring gasket is positioned circumferentially around the exterior of the tubular section of the first member. The lower end of the tubular section of the second member contacts the O-ring gasket. The O-ring is stretch-fit over the first member and prevents the second member from telescoping downward on first member past a desired insertion position.

Abstract: An elastomeric gasket comprises an annular body having an outer surface with a flanged edge, a sealing bead, and a semi-circular locking bead to facilitate insertion, and an inner surface comprising multiple, flexible angularly inwardly-extending lips that are self-sealing under pressure.

Abstract: A method and apparatus for removing contaminants such as heavy metals and organic pollutants from contaminated water using waste cast steel shot blast fines is described. Shot blast fines were hitherto disposed of by the iron processors at significant cost. In another embodiment, waste shot blast fines are used to fix heavy metal and organic contaminants in groundwater and water runoff from contaminated landfills and industrial sites.

Abstract: An improved mechanical pipe joint for use in a bell and plain pipe end assembly. The joint includes a gland having a conical cavity for receiving a toothed split ring that coaxially compresses and grips the plain pipe end as the gland is tightened to the bell. The joint is sealed by a compressible gasket positioned between the split ring and the bell. The gland further includes an integrally formed, radially extending shelf for abutting against the split ring and mechanically stopping the gland from being pulled over the split ring during joint assembly.

Abstract: Each half of a bifurcated circumferential clamp includes a pair of spaced apart internally oriented semicircular ridges for engaging grooves formed at the end of abutting pipes. Teeth extending adjacent the ridges penetrate the groove walls to physically lock the clamp with the pipes. A circular gasket bridging the abutting pipes and held in place by the clamp seals the junction between the pipes.

Abstract: A mechanical pipe joint comprising a substantially cylindrical body integrally formed with a plurality of pipe restraining members, and a plurality of pipe clamping members, each comprising at least one block slidably engaged with a pipe restraining member, a compressible gasket for graduating suddenly applied forces, and restraining bolts. The clamping system, acting to distribute the clamping forces on a large portion of the surface area of a pipe, simultaneously absorbs and graduates suddenly applied forces, preventing failure of the pipe point.

Abstract: A roof drain receptacle for mounting on the roof deck of a roofing structure and including an upwardly opening drain body with an externally disposed apparatus for adjustably extending and supporting the drain body so that its open upper end is in the proper drain water receiving position relative to the top surface of the roofing structure.

Abstract: A closet flange assembly for anchoring a water closet to a floor and sealingly connecting the water closet to a waste drain conduit. The closet flange assembly includes a drain body having a flange for attachment to the floor and to the water closet and having a compression gasket circumferentially compressingly contained and held against axial movement within the axial bore provided in the drain body. The compression gasket has an axial bore which provides an interference fit with the periphery of the waste drain conduit when the drain body and compression gasket are axially slidingly pushed onto the waste drain conduit.
