Patent number: 7430867Abstract: A duct comprising an inner casing spaced apart from an outer casing and which also comprises a number of interfaced duct sections must be assembled in such a way to prevent relative redial movement between the casings and thereby inhibit buckling. The present invention is a duct which utilises abutment members which longitudinally extend from each of the inner walls across the interface of the duct sections. The abutment members are radially spaced apart in normal use but are configured such that substantially relative radial movement of the inner and outer walls is prevented when the overlapping members abut.Type: GrantFiled: December 14, 2004Date of Patent: October 7, 2008Assignee: Rolls-Royce plcInventor: Michael John Agg

Publication number: 20080236693Abstract: The invention relates to an exhaust pipe assembly. There is a need for an exhaust pipe assembly which transmits less noise to the environment. The exhaust pipe assembly includes a hollow exhaust pipe, and a hollow shield which surrounds at least a portion of the pipe. The shield is supported from and separated from the pipe by a plurality of elastomeric support elements which are interposed between the pipe and the shield. Each support element includes a larger body positioned between the pipe and the shield, and a smaller stem which projects from the body and extends into a bore formed in the shield. Each support element is preferably formed by injecting an elastomeric material through a corresponding one of the bores to form the body in the space between the pipe and the shield.Type: ApplicationFiled: March 30, 2007Publication date: October 2, 2008Inventors: Norman Everett Muzzy, Jason Michael Edgington

Publication number: 20080229800Abstract: Substantially scrapless methods for fabricating angled ductwork fittings. The methods include cutting a pre-determined pattern into a blank comprised of sheet metal material to separate the blank into two or more portions. Bending each of the portions of the blank so that each portion forms a rectangular section of ductwork pipe and joining the sections of ductwork pipe together to form an angled fitting. A transition fitting comprising a transition plate including a first panel and a second panel. The first panel is sized and shaped to be positioned in and to blank-off a gap between a first pipe and a second pipe. The second panel is positionable within the first pipe to direct fluid traveling through the first pipe into the second pipe.Type: ApplicationFiled: March 20, 2007Publication date: September 25, 2008Inventor: Leslie E. Santeler

Publication number: 20080178956Abstract: A fluid distribution apparatus is positioned within an interior passageway of an existing conduit. The conduit is part of a fluid collection system. The fluid distribution apparatus includes at least one stabilizing member and at least one receptacle. The at least one stabilizing member engages at least a portion of a sidewall of a portion of the conduit defining the interior passageway extending through the conduit. The at least one receptacle is supported by the stabilizing member. The at least one receptacle has at least one passageway extending therethrough. The at least one passageway sized and dimensioned to receive at least one pipe while permitting fluid to flow through the interior passageway of the existing conduit.Type: ApplicationFiled: January 26, 2007Publication date: July 31, 2008Inventor: Bruce Willingham

Patent number: 7367363Abstract: Apparatus for supporting conduits within a sanitary environment. Some supports are configured so as to avoid the formation of surfaces that might collect dust, debris, cleaning fluids, etc. when installed. In one embodiment, the support includes a pair of opposing support members that may be releasably and sealingly secured together. The upper support member may have a substantially uninterrupted convex surface that has a desired texture. The lower support member may be sized and shaped such that no portion thereof protrudes outwardly beyond the upper member to form any surfaces, pockets, etc. wherein dirt, debris, cleaning fluids, etc. may accumulate. A seal or grommet may be employed to establish a seal between the conduit and support to prevent the infiltration of dirt, debris, cleaning fluids, etc., between the conduit and the conduit support.Type: GrantFiled: December 19, 2005Date of Patent: May 6, 2008Assignee: PBM, Inc.Inventors: Gary W. Friedline, Robert S. Chappo, Jr., Kenneth R. Graham

Patent number: 7318453Abstract: A spacing and centering device for a rigid double-wall duct, for example of the winding type, which is intended for the transport of hydrocarbons. The rigid duct comprises two coaxial tubes which are separated by an annular space. The spacing and centering device is housed in the annular space in order to maintain a distance between the two coaxial tubes. An element made from a material having low heat conductivity and comprising an aerogel element is at least partially covered with a casing of polymer-type plastic material.Type: GrantFiled: September 1, 2004Date of Patent: January 15, 2008Assignee: Technip FranceInventor: Philippe Hoffmann

Patent number: 7225837Abstract: An integrated casing spacer and joint restraint unit is attached to each of a pair of pipe sections adjacent to an end-to-end connection of the pipe sections by means of first and second spacer/retainer ring members. Disposed on the outer periphery of each ring member in a spaced manner are plural risers each having a respective runner disposed on its outer end for engaging an inner surface of an outer casing and maintaining fixed spacing between the inner pipe sections and the outer casing. Plural paired risers, with one riser disposed on each ring member, are aligned with one another along the axis of the connected pipe sections and are each adapted for secure connection to a respective connecting rod for securely coupling the two ring members together and restraining relative movement between the two pipe sections.Type: GrantFiled: September 1, 2006Date of Patent: June 5, 2007Assignee: Cascade Waterworks Manufacturing Co.Inventor: William L.
