Patent number: 6832624Abstract: 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 value 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: October 8, 2003Date of Patent: December 21, 2004Assignee: Waterfall, Inc.Inventor: Joseph D.

Publication number: 20040089342Abstract: The disclosed method & apparatus are for forming a fluid connection or tap through the wall (1) of a pipeline, particularly intended for “for tapping” of subsea pipelines. The method comprises fitting a connecting piece (2) having a mounting surface which extends around the tap location (2g) and at least partially over the tap location (2n) and a connecting wall (2h) which surrounds the tap location to provide an opening (2k) adapted or subsequent connection of a conduit to complete a fluid connection. The connecting piece is bonded to the pipeline by friction stitch welding performed (4, 6) inside said opening. The material at the tap location is removed (AC indicates after cutting) to define an aperture and provide said fluid connection surrounded closely by the weld (6) between the connecting piece and the wall.Type: ApplicationFiled: December 15, 2003Publication date: May 13, 2004Inventors: Olav Vennemann, Axel Meyer, F.

Patent number: 6691734Abstract: A method, system and tools for introducing a fiber optic conduit into a pressurized gas pipeline includes the step of introducing a translating member into the pressurized gas pipeline via an entry port in a first fitting attached to the pressurized gas pipeline. Tools are deployed within a first pressure lock housing attached to the first fitting by using a first manipulator located in the first air lock housing. The translating member, such as a duct rod, is advanced within the pressurized gas pipeline by a driving mechanism until a second drilling fitting is reached. The translating member is attached to a fiber optic conduit or cable. The duct rod and fiber optic conduit are then pulled back through the pressurized gas pipeline. Extractor tools extending through seals in the pressure lock housing engage with and withdraw the duct rod. Alternatively, first and second duct rods may be pushed towards each other from the first and second fittings. End elements on the duct rods engage each other.Type: GrantFiled: May 29, 2002Date of Patent: February 17, 2004Assignee: Sempra Fiber LinksInventors: Scott A. Beals, Ronald D. Hammer, Robert E.

Patent number: 6691733Abstract: A tapping connector for a pipeline, vessel or the like wherein the connector has a membrane disposed therein. The membrane may be curved or arcuate and may be configured to offer a partially cylindrical profile that resembles the wall of a pipe. The tapping connector may be used to provide future connection points for branch lines to the pipeline, vessel or other containment structure. The membrane so configured may be removed by conventional pipe tapping equipment.Type: GrantFiled: November 4, 1997Date of Patent: February 17, 2004Inventor: Bruce E. Morris

Patent number: 6681795Abstract: A method of introducing a fiber optic conduit into a pressurized gas pipeline includes the step of introducing a translating member into the pressurized gas pipeline via an entry port in a first drilling fitting (18) (8, 70, 250, 300) attached to the pressurized gas pipeline. Tools are deployed within a first pressure lock housing (30) attached to the first drilling fitting by using a first manipulator (34) located in the first air lock housing. The duct rod is advanced within pressurized gas pipeline by a driving mechanism (60), until a second drilling fitting (80) is reached. The translating member is attached to a fiber optic conduit or cable. The duct rod and fiber optic conduit are then pulled back through the pressurized gas pipeline by the driving mechanism. A conduit or cable is installed in a gas service line, to provide an optical fiber between an optical fiber trunk line or ring and building.Type: GrantFiled: October 9, 2001Date of Patent: January 27, 2004Assignee: Sempra Fiber LinksInventors: Scott A.

Patent number: 6516496Abstract: A device for facilitating manual gripping of pipes and connectors includes first and second elements hingedly interconnected and biased open by a spring element. Each element includes a channel with projections deployed to define gripping features for gripping a roughly cylindrical object of given outer diameter. The first and second elements provide grasp surfaces which, in the closed position, lie within a cylindrical volume of diameter four times the given outer diameter and generally circumscribe the object.Type: GrantFiled: March 26, 2001Date of Patent: February 11, 2003Assignee: Easy-Con Ltd.Inventor: Amir Ekron

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.

Publication number: 20020106247Abstract: This invention contemplates a resettable plug assembly suitable for insertion into a pipeline from a transverse tee connection in order that flow may be stopped and pressure retained by the plug. The stopper plug is inserted in the upstream direction and utilizes a bypass valve to aid installation when there is flow. The seal of the plug is expanded radially to contact the wall of the pipeline for sealing. Once in place the bypass valve is closed to stop the flow in the pipeline.Type: ApplicationFiled: February 1, 2002Publication date: August 8, 2002Inventor: Larry R. Russell
