  • Patent number: 5419593
    Abstract: A process to install an interlocking union for joining a first double containment pipe having a first carrier pipe within a first containment pipe to a second double containment pipe having a second carrier pipe within a second containment pipe. The process includes slipping a first locking ring into position over the outside diameter of the first carrier pipe to stop against the first containment pipe. A carrier coupling is adhesively bonded to the first carrier pipe stopping against the first locking ring. Thereafter, a second locking ring is slipped into position over the second carrier pipe stopping against the second containment pipe. The carrier coupling is adhesively bonded to the second carrier pipe stopping against the second locking ring. Finally, a containment coupling is bonded to the first containment pipe and to the second containment pipe.

    Abstract: A flexible pipe connector is disclosed for connecting to a hard plastic pipe. The flexible pipe connector, preferably made of polyethylene, has a tubing member which defines a cylindrical wall with inner and outer surfaces, the cylindrical wall having a male end which has a plurality of undercuts formed on the outer surface. The male end with the undercuts is inserted into the female end of a hard plastic pipe with a melting agent applied at the inner surface thereof. The melting agent melts the inner surface of the pipe's female end to form a liquified layer of hard plastic which is received in the male end's undercuts and then hardens into a reconfigured solid layer. In this manner, the flexible pipe connector, which is inert and normally cannot be attached with glue to a hard plastic pipe, can be sealably secured to a hard plastic pipe as the liquified layer solidifies within the undercuts to prevent separation of the pipe connector and the hard plastic pipe and to provide a seal therebetween.

  • Patent number: 5330449
    Abstract: A strain relief device for use at a tube/hub junction of a tubular device such as a catheter. The strain relief device forms a lumen which may have a reduced diameter at a distal section thereof which can cooperate with the outer diameter of a catheter tube to form a wicking surface. The wicking cavity is formed to allow bonding material to be added thereto which, through capillary action, forms a uniform and controlled bond pattern between the strain relief device and the catheter tube. A catheter including the strain relief device of the invention is manufactured by inserting the strain relief device over a catheter tube/hub junction and permanently bonding the proximal end of the strain relief device to the hub in a conventional manner. The distal end of the strain relief device is then bonded to the catheter tube. The stain relief device of the present invention resists axial pulling forces, as well as bending forces, which may be applied to the catheter.

  • Patent number: 5181750
    Abstract: Improved male/female hose couplings for opposite ends of a hose are disclosed. Each of the couplings is injection molded from a strong plastic material such as polyvinylchloride, and includes coupling member having internal projecting and external coupling portions. The internal projection portion is diametrically sized for insertion into the hose bore and is chemically bonded to the hose. The external coupling portion of the male coupler is externally threaded. The female portion is internally threaded and also includes radially extending tabs to facilitate rotation. A strain relief device in the form of an extruded coil spring extends from the coupling and encircles the hose end, protecting the hose from fracture by repeated bending. In an alternative embodiment, the strain relief device takes the form of a thickened sleeve of softer material such as a plasticized vinyl, and is formed with a plurality of radially extending disks that limit the degree of bending movement of the hose end.

  • Patent number: 5174611
    Abstract: An improved releasable coupling for a tube is disclosed. The coupling contains a socket with at least four stepped bores. Located within the first bore is a compresion means (such as a collar) which has an inner surface inclined to the axis of first bore. A collet is mounted within the compression means and is so configured that, when the collet is caused to move inwardly, the inclined surface of the compression means causes the jaws of the collet to move inwardly. The coupling also contains a tube support located within the second bore. At least four sealing means are disposed within the third bore: a first O-ring is contiguous with a first washer, which in turn is contiguous with a second O-ring, which in turn is contiguous with a second washer.

  • Patent number: 5163714
    Abstract: A joint for end-to-end coupling of two tubular elements includes tapered coupling surfaces on the tubular elements which are bonded together by adhesive. The coupling surfaces comprise a plurality of cylindrical sections of gradually increasing and decreasing diameters, respectively. A plurality of axially spaced-apart centering rings are interposed between the tubular elements to provide proper positioning thereof and to facilitate injection of bonding material between the coupling surfaces. A series of axially spaced-apart conducting rings forming part of an antenna surround one of the tubular elements and are insulated therefrom by a layer of bonding material. The conducting rings are separated from each other by toric joints and shims. Openings are provided in one of the tubular elements for injecting the bonding material under pressurized conditions, and an insulating sheath is bonded to inner peripheries of the tubular elements.

  • Patent number: 5143117
    Abstract: A check valve assembly is disclosed for use with a pool or spa plumbing system and includes first and second hub sections connected together by a nut member. An insert member carrying an elastomeric diaphragm is sandwiched between the first and second hub members to permit fluid flow in a first direction and prevent fluid flow in a second reverse direction. The assembly is designed such that the nut member may be moved longitudinally along one of the hub sections to expose and permit removal of the insert member in a direction transverse to the longitudinal axis of the hub sections. The nut member and insert are configured to cooperate with each other such that the insert may only be mounted in the assembly facing in a predetermined direction.

  • Patent number: 5131687
    Abstract: A disconnectable device for making a sealed connection quickly between a smooth and rigid tube and a flexible hose which is engaged over the rigid tube, the diameter of the tube being greater than the inside diameter of the hose. A rigid ring preferably made of metal or of a semi-rigid plastic, is disposed coaxially around the hose, the ring having an inside shoulder constituting an axial abutment for the outside surface of the hose, the abutment sufficing on its own, by virtue of the wall of the hose being pinched thereagainst, to urge together the sole pair of complementary sealing surfaces of the device, one on the tube and the other on the inside surface of the hose. Complementary axial fastening means are connected respectively to the ring and to the tube.

  • Patent number: 5127116
    Abstract: A joint between pipes (12, 14) each having a liner (16, 18) of polyolefin such as polythene. The pipes are spaced apart and the liner protrudes from each and is joined to its neighbor by a fusion coupling (20). The pipes are interconnected by a shell (24, 26, 28) and epxoy cement grout (34) fills the space between the liner and the shell. The liner is inserted in the pipe after it has been reduced in diameter by passing it through a die. The pressure of gas or liquid within the liner in use is greater than the liner can withstand alone but the grout transfers pressure loading to the shell. In modifications the coupling is replaced by a PECAT coupling or by flanged couplings joined to the pipes by butt fusion or by electrofusion directly or using electrofusion couplers. The liner may be locked in position using electrofusion fittings to prevent change of dimensions by reversion.
