A tubular liner extends through the bore of the grommet and contacts the first and second sections. The plurality of ribs extend into the bore, and at least some of the ribs contact the liner.

Abstract: A compressor which has a pipe coupling structure capable of fluid-tightly connecting a refrigerant pipe to a pipe coupling port, without needing any welding process to connect the pipe to the pipe coupling port, and a method of connecting the refrigerant pipe to the pipe coupling port of the compressor. The compressor includes a pipe to form a refrigerant path through which a refrigerant flows, a pipe coupling port connected to the pipe, and a hollow bushing having an inner surface to define a hole to receive an end of the pipe, and an outer surface to come into contact with the pipe coupling port, when the hollow bushing is thrust at an end thereof, at which the end of the refrigerant pipe is placed, so as to be compression-fitted into the pipe coupling port.

Abstract: Apparatus has a vessel fitting (2) and a retainer (10) that connect a core spray pipe system (4) to an opening (14) in a wall (8) in a vessel (9) in a boiling water nuclear reactor. The vessel fitting (2) has a plurality of resilient beams (76a), (766b), (76c), (76d), 76(e) and 76(f) arranged to extend into the opening (14) and lock the vessel fitting (2) in place on the vessel. The retainer (10) is installed on the vessel fitting (2) by inserting it through a passage (79) in the vessel fitting (2). The retainer (10) bears against the beams to maintain them in locking engagement with the vessel.

Abstract: A pipe coupling for transverse connection of a drainpipe to a concrete sewer pipe of larger relative diameter. The coupling has a hollow, longitudinally extending cylindrical body with first and second ends and interior and exterior surfaces. The body has an external locating shoulder, on the exterior surface, integral with the body and extending outwardly therefrom. The external locating shoulder limits penetration of the coupling in an opening in a sidewall of the concrete pipe. The body also has an internal groove on the interior surface, located at a same longitudinal spacing as the external locating shoulder. The internal groove receives an internal sealing ring for creating a seal between the drainpipe and the body when the drainpipe is inserted.

Abstract: A bubble jet fitting for use in a pool or spa provides for a lay-length short enough to allow its installation within a six-inch dam wall. The bubble jet fitting has an outlet portion which in one use provides for solvent welding therein of either one of two different standard sizes of PVC pipe. An axially extending annular recess of the fitting may receive a surfacing layer of plaster or fiberglass to form a water-tight interface with the surrounding wall of the pool or spa.

Abstract: A heat exchanger is disclosed with one piece manifolds formed from a unitary sheet of metal. Each manifold has first and second sidewalls and a third sidewall extending therebetween the a lap joint between the side edges of the metal sheet. The first and second sidewalls are flat and the first is provided with tube apertures for receiving cooling tubes extending between a pair of manifolds. The second sidewall is flat and is provided with a socket for receiving the end of a pipe fitting in an interlocking connection. The manifold is clad on both sides with a brazing material and the manifold assembly with all attached parts are heated in a brazing oven to effect final assembly of the heat exchanger.

Abstract: In a piping system having a main pipe or fitting joined to a lateral pipe, a restraint body or sling extends about the fitting or main pipe and is secured at opposite ends to the lateral pipe. The lateral pipe, main pipe or fitting and restraint body are formed of plastic material. The restraint body includes a bend intermediate its ends for wrapping about the fitting or main pipe and has arcuate sections at its ends for solvent-welding to the lateral pipe. Any tendency toward separation of the lateral pipe and the main fitting or main pipe is resisted in tension by the restraint body and the joint is stress-relieved.

Abstract: A vacuum cleaner hose assembly has a corrugated, flexible hose with fittings at opposite ends for connection to the vacuum cleaner suction inlet and to a cleaning head. A tube or cable extends along the assembly for supply of cleaning fluid or electrical power to the cleaning head. The tube or cable is retained with the hose by means of a U-shape channel provided as a separate member bonded to the outside of the hose. The tube or cable extends within the channel as a loose fit so that it can move along the channel on flexing of the hose, thereby helping maintain flexibility of the assembly.

Abstract: A one piece integrally formed liquid tight connection or "whip" assembly for electrically interconnecting electrical appliances, such as air conditioning units, hot tubs, swimming pools and outdoor lighting fixtures, to one another and/or to a power source junction box or control box. The connection assembly includes a flexible tubular conduit, preferably constructed from a composite of full rigid PVC and flexible plasticized PVC, having first and second end portions and an outer surface with a plurality of surface irregularities. A pair of end fittings are integrally attached to the first and second end portions of the tubular conduit, respectively, using either a solvent welding or temperature welding technique. When using the solvent technique, the plurality of surface irregularities operate to hold additional localized amounts of solvent which further reacts with the plastic in the end fittings and conduit to yield a superior weld.

Abstract: An apparatus which creates a pre-engineered solvent bond is disclosed which acts to self-optimize the characteristics of the resultant solvent bond. These characteristics can thus be chosen by the part designer with confidence that inherent variations in the assembly process will not unduly impact the resultant bond. The design establishes a specific volume through integral tabs or removable shims within which solvent acts to precisely dissolve material so that the predetermined bond characteristics are automatically created without reliance upon assembler technique.

Abstract: A hot tap connection comprising: (i) a main supply pipe, (ii) a side branch pipe connected to the main supply pipe, (iii) a reinforcing saddle surrounding the main supply pipe and the side branch pipe, (iv) a first gap between the main supply pipe and the reinforcing saddle, (v) a second gap between the side branch pipe and the reinforcing saddle, and (vi) a solid material substantially filling the first gap and the second gap. The method for producing the hot tap connection is also described.

Abstract: A quick connect coupling for tubing. The coupling includes a tubular male connector member adapted to be telescopically received within a tubular female connector member assembly. The female assembly includes a first member defining a seal bore and a cylindrical socket portion forwardly of the seal bore. A second female member includes a cylindrical portion which plugs into the socket of the first member and is held in position relative to the first member by sonic welding. A plurality of circumferentially spaced feet on the inner end of the second member are positioned proximate the seal to hold the seal in the seal bore and further engage the outer periphery of the pilot portion of the male member to minimize cocking of the male member relative to the female assembly.
