  • Patent number: 7984934
    Abstract: Copper purge fittings for brazing components of a special gas delivery line together are provided. An orifice is located on the top or end portion of each fitting to create a continuous flow of inert purging gas through the delivery line under construction while brazing. Each fitting will reach temperatures exceeding 1500 degrees. By having a continuous flow of inert gas while brazing, the protection of the interior portion of the system remains intact. Without a purge in place, the intense heat would create a rapid immediate buildup of carbon and other contaminates. Brazing is only commenced after the elimination of harmful oxygen and proper flow of purging gas is measured. The purging gas pressure is lowered if it becomes high enough to potentially cause separation of tubular sections from the purge fittings and is raised if a low flow rate is detected indicating potential insufficient flow of purging gas.

  • Publication number: 20100289196
    Abstract: An overhead wire tension balancer has a water draining structure and can prevent lubricating oil in the tension balancer from scattering to the outside. The overhead wire tension balancer is for supporting a spanned overhead wire while applying tension thereto, and rainwater collecting inside the overhead wire tension balancer is collected from a collecting pipe connecting part into a collecting tank through a collecting pipe. The oil content of grease applied to the inside of the overhead wire tension balancer is prevented from scattering to the outside even if the oil content is carried together with the rainwater.

  • Publication number: 20100288018
    Abstract: The application relates to a connector (11) for connecting at least a portion of a double-wall tubing (9) to a high-pressure line (4) and a fuel system having a high pressure line (4), a double wall tubing (9) and connector for coupling the double-wall tubing (9) to the high-pressure line (4). The connector (11) is configured to establish a fluid connection between a portion of the double wall tubing (9) and the high pressure line (4). The connector also provides a fluid detection passage, and a fluid connection between another portion of double wall tubing and said fluid detection passage. The application also relates to a method for detecting a leakage in a fuel system of the above type, having a plurality of first detection units and a second detection unit, in which fuel leakage, which may stem from different areas of the fuel system, may be detected by at least one of said first and second detection units.

  • Publication number: 20100207379
    Abstract: A fluid conduit coupling for a turbofan engine wherein the engine has a gas path defined by inner and outer duct walls and the exterior surface of the outer duct wall is readily accessible for visual inspection. In one example, a first fluid line extends across the gas path between the inner and outer duct walls and a second fluid line is connected to the first fluid line at the level of the outer duct wall. The first fluid line may include a female coupling member and the second fluid member may include a mating male coupling member. An annular sealing member is associated with the first and second couplings and a leak path is defined between the annular sealing member and the exterior surface of the outer duct wall, whereby fluid may be detected by visual inspection of the outer duct wall if a leak should occur at the annular sealing member.

  • Patent number: 7753412
    Abstract: A vented gas riser for use in a system for conducting pressurized gas through a gas carrier pipe from a gas supply source line located below ground level to a delivery point disposed above ground is provided. A fluid tight gas riser protective casing is disposed around said carrier pipe and creates a gas escape passageway in an elongate annular space between the carrier pipe and the casing. Any gas which leaks from the gas carrier pipe is captured in the gas escape passageway. A riser transition head, which includes at least one vent passageway, provides a fluid connection with said gas escape passageway and with the atmosphere such that any gas which leaks in the vicinity of the gas escape passageway can escape through the at least one vent into the atmosphere.

  • Patent number: 7744018
    Abstract: A power operated pressure washer having a high pressure liquid supply hose with an inlet fitting formed with an axial stem having a central liquid passageway that can be connected to a pressure washer outlet fitting by a threaded retaining ring. As a feature of this invention, the retaining ring can be unscrewed from the pressure washer outlet for permitting the dissipation and venting of high pressure buildup within the hose while the retaining ring safely retains the hose fitting on the outlet. In one embodiment, the stem has a pair of axially spaced annular sealing members adaptable for sealing engagement with relatively smaller and larger size pressure washer outlets and the stems is formed with a transverse passageway for venting liquid from the central stem passageway around one of the sealing members, as an incident to unscrewing of the retaining ring, while the other sealing member remains in sealed engagement with the pressure washer outlet fitting.

  • Patent number: 7740284
    Abstract: A vented gas riser for use in a system for conducting pressurized gas through a gas carrier pipe from a gas supply source line located below ground level to a delivery point disposed above ground is provided. A fluid tight gas riser protective casing is disposed around said carrier pipe and creates a gas escape passageway in an elongate annular space between the carrier pipe and the casing. A containment chamber is disposed below ground level which creates a confined space which has, as its only egress, a fluid connection to a gas escape passageway. Any gas which leaks into the containment chamber is directed into the gas escape passageway. A riser transition head, which includes at least one vent passageway, provides a fluid connection with said gas escape passageway and with the atmosphere such that any gas which leaks into said containment chamber is directed through the gas escape passageway and through the at least one vent and into the atmosphere.

  • Patent number: 7722093
    Abstract: The invention relates to a fitting for connecting lengths of pipe by compression, having a substantially cylindrical internal contour. The fitting has a ridge which is configured in a radially outward direction and in which a sealing element is provided. The fitting is slidable onto the lengths of pipe, the internal contour having a region of non-circular cross-section. The invention also relates to a connecting arrangement for connecting lengths of pipe by compression, comprising a length of pipe and a fitting plus a sealing element which is arranged in the ridge. One axial gap which extends over the entire connecting region is formed between the length of pipe and the internal contour of the fitting in the uncompressed state. Such an axial gap with an open end would ensure that a leak exists even in the region of the sealing element in an uncompressed state.

  • Patent number: 7717470
    Abstract: A quick fluid connector includes two mating portions. Leakage may occur during mating and demating. In order to contain such leakage, the mating portions of the connector are mounted on the distal end of a projecting boss and at the fundus of a matching well, respectively, so that the boss and well together define a chamber which surrounds the two mating portions of the quick connector. One or more drainage channels are coupled to the chamber to carry away leakage.

    Abstract: A docking system for docking a liquid stream carrying line to a docking body, a line end for docking a liquid stream carrying line to a docking interface of a docking body, as well as to a method for preventing liquid from continuing to flow when undocking a line end of a liquid stream carrying line from a docking interface of a docking body. The docking system includes a line end having a first form that is conically tapered in the direction of flow and a docking interface which is situated on the docking body and has a second form that is conically tapered in the direction of flow. The first conically tapered form and the second conically tapered form are adapted to one another in such a way that, in the docked state, they are mutually set apart in one coupling region by an interspace defined by a sealing ring, concentrically opposing one another.
