Patent number: 6508267Abstract: A plumbing tool includes an elongated hollow shaft and a resilient member attached to the shaft adjacent a shaft end. The resilient member extends radially outward and is sized to closely fit within a pipe inner diameter. Once the pipe has been cut, the tool is forced into the pipe end and the resilient member closely fits within the pipe inner diameter to block fluid flow. As the shaft is hollow, fluid flow is diverted through the shaft. A valve is then passed over the tool to engage the pipe end. As the fluid is being diverted through the tool, the valve is then soldered to the pipe without concern for the heat sink effect of fluid passage through the pipe. Once the valve has been properly soldered to the pipe end, the tool is simply pulled through the valve and removed. Capping of the pipe end with the valve is therefore rapidly achieved with minimal disruption to the users.Type: GrantFiled: March 14, 2002Date of Patent: January 21, 2003Assignee: Waterfall, Inc.Inventor: Joseph D. Rippolone

Patent number: 6508274Abstract: The present invention is directed towards a dust plug for insertion into a fluid conduit system. The dust plug is comprised of an insertion end, removal means, and a hollow central body located between the insertion end and the removal means. The insertion end of the plug is formed as a solid flat end so that when the plug is inserted into the fluid conduit system, the hollow interior of the plug does not communicate with the interior of the system. Additionally, the removal means is preferably formed as a continuous lip about the end of the hollow central body.Type: GrantFiled: December 4, 2000Date of Patent: January 21, 2003Assignee: The Goodyear Tire & Rubber CompanyInventor: David Gene Street

Patent number: 6508275Abstract: A molded fuel filler pipe for use in automobiles, in particular cars, comprises a one-piece structure which is blow molded. The conduit produced in the blow mold has a smooth edged tubular portion and a bellows portion which is molded at the same time. By deforming the bellows portion, flexibility in the relative location of the two ends of the conduit is provided. This eliminates taking two separate pieces and joining those pieces which may give rise to fuel vapour permeation through the joints.Type: GrantFiled: March 15, 2000Date of Patent: January 21, 2003Assignee: Salflex Polymers Ltd.Inventors: Changize Sadr, Sam Shafiee

Patent number: 6508276Abstract: A textile tubing comprises inner and outer coatings, and a material made of warp and weft threads manufactured from high tensile strength and high modular strength fibers (high performance fibers) disposed between the coatings. The warp threads are arranged in the longitudinal direction of the tubing and the weft threads are arranged in the circumferential direction of the tubing. The inner and outer coatings are made of a thermolastic synthetic material. The weft thread width is at least 8,000 decitex (dtex) and, preferably, more than 10,000 dtex. The warp thread width is at least 2,000 dtex and, preferably, more than 3,000 dtex. The weft density is at least 40 and preferably more than 50. The textile tubing is especially suitable for cleaning high pressure liquid lines. The textile tubing does not have to be stuck to large surface areas of the inner wall of a pipe due to its high burst pressure of more than 90 bar.Type: GrantFiled: February 28, 2002Date of Patent: January 21, 2003Assignee: Radlinger Maschinen-und Anlagenbau GmbHInventors: Josef Rädlinger, Horst Stimmelmayr, Frank Heinze, Frank-Michael Köpping

Patent number: 6508277Abstract: The present disclosure relates to a flexible pipe including a pipe body that extends along a central longitudinal axis. The pipe body is made from a strip that is helically wrapped in a plurality of convolutions. The strip includes inner and outer hook portions that interlock to form an interlock seam between adjacent convolutions. The pipe body includes a mid-portion positioned between first and second end portions. At least the first end portion has an axial length L1 that traverses at least several of the convolutions of the pipe body. The first end portion is crushed radially inward relative to the mid-portion such that the first end portion has an effective outer diameter D1 that is smaller than an effective outer diameter D2 of the mid-portion. A first transition region is positioned between the first end portion and the mid-portion. The first transition region provides a diameter transition between the outer diameter D1 of the first end portion and the outer diameter D2 of the mid-portion.Type: GrantFiled: July 27, 1999Date of Patent: January 21, 2003Assignee: Donaldson Company, Inc.Inventors: Julian A. Imes, Wayne M. Wagner, John T. Herman

Patent number: 6508278Abstract: An on-machine-seamable papermaker's fabric produced by modified endless weaving includes machine-direction (MD) and first cross-machine-direction (CD) yarns. The MD yarns weave continuously back and forth between the two widthwise edges of the fabric, each time forming a seaming loop at one of the two widthwise edges. The MD and first CD yarns are interwoven with one another in a first weave pattern. The fabric also includes systems of second and third CD yarns. The second CD yarns are interwoven with the MD yarns along one of the two widthwise edges of the fabric between the system of first CD yarns and the seaming loops in a second weave pattern which may be different from the first weave pattern. Likewise, the third CD yarns are interwoven with the MD yarns along the other of the two widthwise edges of the fabric between the system of first CD yarns and the seaming loops in a third weave pattern which may be different from the first weave pattern.Type: GrantFiled: November 23, 2001Date of Patent: January 21, 2003Assignee: Albany International Corp.Inventor: Glenn J. Kornett
