Abstract: A sewer line coupling device to facilitate attachment of a recreational vehicle sewer line to a fixed waste pipe. The coupling device comprising a main body having a second end for insertion into the waste pipe. A movable member is movable relative to the main body and a sealing sleeve is supported by the main body adjacent the second end. One end of the sealing sleeve is affixed to the main body while the other end is coupled to the movable member. When the movable member is moved in a first direction, a minimum dimension of the sealing sleeve is achieved to facilitate insertion into the waste pipe and, when the movable member is moved in an opposite direction, a maximum dimension of the sealing sleeve is achieved to facilitate formation of a seal with the waste pipe. A flange is supported by the main body between the first end and the second end thereof.

Abstract: A coupling for attachment to the end portion of a pipe includes jaw members adapted to slide along an inner end taper in the coupling body so that linear movement of the jaw members toward the end of the inner end taper adjacent an end of the coupling body causes movement of the jaw members radially inwardly of the coupling body against the end portion of the pipe when received in the coupling body. The coupling may include a bell type gasket to function as a spring and the spring action of the gasket may be augmented by installing a springy crib ring around the gasket inside the coupling body.

Abstract: A mechanical type boot including a vertically positioned riser in a tubular configuration with an outwardly flanged upper end and an outwardly flanged lower end. Vertical bolt holes are provided through the ends. Vertical bolt holes are provided in a lower flat end of a base flange. Vertical bolt holes are also provided in a flanged lower end of a generally cylindrical split seal cap ring. Vertically extending bolts couple the riser, seal and base flange. An inverted J-shaped tube constitutes a gas well pipe. The tube has a long vertical section located within and extending upwardly from the split seal cap ring. The next intermediate section extends outwardly. A third outboard section extends downwardly for the exhaust of gasses. The lowermost end of the gas well pipe is held in a fluid type relationship with regard to the split seal cap ring.

Abstract: A high pressure hose fitting, and method for sealing the hose to a fitting, is disclosed for use with hoses of the type including a linear disposed about an axially extending passageway, and a reinforcement layer circumventing the liner. The liner is preferably pulled slightly beyond the edge of the reinforcement layer to form a protruding edge region. An end fitting, having a flange with a liner-receiving groove, is inserted into the passageway until the protruding edge of the liner contacts the end wall of the groove, and the flange abuts the reinforcement layer. A swagable collar circumventing the foregoing components is swaged radially inwardly to clamp the liner on its outside diameter.

Abstract: A zero-leak cryogenic coupling includes a polymeric seal clamped to a male bayonet member with two pairs of tightening rings. The tightening rings threadably engage each other in respective pairs around tapered ends of the inflatable seal member so that a wedging action tightens the seal member about the male bayonet. Once in place, the seal may be inflated via an inflation port so that its expansion provides a pressure contact with the inside surface of a coaxial female member.

Abstract: A telescopic joint for repairing underwater pipelines laid at a great depth in which an annular sheath of steel having a yield point of not more than one half that of an outer sleeve of the joint is welded onto an inner cylinder, to create with the inner cylinder an annular chamber or interspace, the cylinder-sheath-sleeve assembly being guided in its telescopic movement by an inner tube welded coaxially to an end of the outer sleeve. The interspace is connected to an oil pump which under adequate pressure can cause the steel sheath to expand, to the extent that it yields, to interlock with the outer sleeve.

Abstract: An adapter to be used in conjunction with a tubular flushing device to unclog a drain pipe. The tubular flushing device expands during usage. The tubular flushing device is to fit within the adapter and is to expand during usage into tight contact with the interior wall of the adapter. The fore end of the adapter is tapered slightly to facilitate tight connection with the inlet opening of the drain pipe.

Abstract: A telescoping joint for plastic pipe comprises a pair of sleeve members bonded to adjacent ends of a pair of pipe sections, a tubular body member into opposite ends of which sleeve members telescope, with O-ring seals carried by the sleeve members forming a seal against the inner surface of the body member, and tubular adaptor members which fit on the respective pipe sections adjacent the sleeve members and thread into opposite ends of the body member to provide thrust restraint precluding withdrawal of the sleeve members and the pipe sections therefrom. The joint may be used for in situ repairs of fractured pipe, or may be supplied with pipe sections bonded-in, for use in a telescoping joint or union to be coupled into a pipe line.

Abstract: A connection between two pipes of a pipeline includes a pair of coupling members having externally threaded ends with sealing surfaces projecting from the ends. The threaded ends are advanced into opposite ends of an insulating sleeve fabricated of electrically nonconductive material. Internally threaded end portions of the sleeve are separated by an annular recessed portion. A resilient, nonconductive annular spacer is retained within the annular recessed portion. The spacer includes a pair of inclined inner sealing surfaces positioned in overlying sealing relation with the coupling member sealing surfaces and an outer sealing surface sealingly engaging the insulating sleeve to form a fluid and pressure tight seal around the annular space between the coupling members and the insulating sleeve in addition to electrically insulating the coupling members from each other.

Abstract: The fluid coupling apparatus is disclosed which is adapted for connecting and disconnecting a first and a second fluid carrying member. Male and female coupling members are connected to the first and second fluid carrying members respectively. The female coupling member comprises a female internal orifice having a female radially enlarged portion in the female internal orifice of the female coupling member. The male coupling member frictionally and sealingly engages portions of the female coupling member for temporarily securing the male coupling member to the female coupling member. Flexible means is established in at least a portion of the male coupling member for radially expanding into the female radially enlarged portion upon application of fluid pressure to connect the male coupling member to the female coupling member.
