Patent number: 6015170Abstract: A coupling assembly for connecting components in a piping system comprising a conduit, an annular ring and a gland. The gland comprises a body and a flange portion extending radially therefrom. A circumferential groove is formed along an inner surface of the body, and the flange portion includes a plurality of spaced bores for enabling attachment of the gland to a mating component in the piping system. The gland preferably comprises two arcuate segments, each segment having bores formed in spaced apart ends thereof to enable the segments to be attached to one another. The annular ring includes a shoulder and an arcuate surface configured to be received in the cooperatively configured groove formed in the gland. The configuration of the ring and the groove enable axial rotation and angular deflection of the gland.Type: GrantFiled: November 26, 1997Date of Patent: January 18, 2000Inventor: Rollow M. Carpenter

Patent number: 5997047Abstract: A high-pressure, flexible, self-supportive piping assembly includes a jointed conduit formed by a plurality of ball and socket joint elements, a flexible internal conduit extending through the jointed conduit, an external sheath, and fittings at opposite ends which communicate with the internal conduit. The sheath is heat shrunk onto the jointed conduit. Each joint element has a ball at one end and a socket at an opposite end whereby the joint elements can be connected serially in end-to-end relationship to form the jointed conduit. The ball of one joint element frictionally engages the socket of the next joint element and, in combination with the stiffness of the external sheath, result in a piping assembly which can selectively configured in shape and which will tend to retain such a shape until subsequently configured.Type: GrantFiled: July 7, 1997Date of Patent: December 7, 1999Inventors: Ralph Pimentel, Gerald Jones

Patent number: 5957768Abstract: An exhaust gas diffuser interface includes a stainless steel shell with varying levels of insulation. The varying levels of insulation concentrate thermal expansion and contraction at the turbine outlet end allowing it to be connected to the outlet by way of a seal weld. This construction allows expansion and contraction of the diffuser interface in unison with the attached turbine outlet, as well as the diffuser inlet.Type: GrantFiled: July 9, 1997Date of Patent: September 28, 1999Assignee: Braden Manufacturing, L.L.C.Inventors: Gene F. Schockemoehl, L. Matt Farabee, David W. Daniels

Patent number: 5951061Abstract: An elastomeric flex joint is provided with a rotational bearing so that torsional stress is relieved by slip of the rotational bearing. In a first embodiment, the flex joint is designed to resist flexing from a mean position at which there is a substantial bend of axial direction, and the rotational bearing does not normally slip. An adjustment mechanism reduces the loading on the elastomeric flex element and the rotational bearing so that the bearing will slip during an initial orientation or during an adjustment of the joint. In a second embodiment, all small torsional deflections are absorbed by the elastomeric flex element, and large torsional deflections are absorbed by the rotational bearing. This is desirable because the elastomeric flex element has a greater fatigue capacity for small oscillations than the rotational bearing. An elastomeric clutch can be used to precisely control the break-out torque.Type: GrantFiled: August 13, 1997Date of Patent: September 14, 1999Assignee: Continental EMSCO CompanyInventors: Edward J. Arlt, III, Benton Baugh, David C. Riggs

Patent number: 5865566Abstract: A catenary riser support, for a floating offshore structure, that receives the riser and is attached to the floating offshore structure. The catenary riser support is formed from a tube that is rigidly attached to the floating structure and a flex joint in line with the catenary riser. The tube includes a gradual bend that complements the natural catenary curve of the catenary riser. A pipe adaptor attached in line with the flex joint and riser allow the flex joint to be pulled up against the tube. The flex joint allows the catenary riser to move relative to the floating structure.Type: GrantFiled: September 16, 1997Date of Patent: February 2, 1999Assignee: Deep Oil Technology, IncorporatedInventor: Lyle David Finn

Patent number: 5839476Abstract: A cable guide (1) consisting of articulated, partially overlapping individual components (2, 3), where the articulation axes (7, 8) of the components (2, 3) run transversely to the longitudinal axis of the cable guide and the individual components (2, 3) are connected together in such a way that the articulation axes (7, 8) of two adjacent components (2, 3) are positioned at 90.degree. to one another. The components (2, 3) include two different alternating basic shapes and each have a removable, snap-on cover (11, 12), where the covers (11, 12) of the cable guide (1) are all directed to one side of the cable guide (1).Type: GrantFiled: August 9, 1996Date of Patent: November 24, 1998Assignee: Igus Spritzgussteile Fur Die Industrie GmbHInventor: Gunter Blase

Patent number: 5803506Abstract: A flexible pipe loop for absorbing or compensating for movement in a pipe run, and for reducing stresses in the pipe run. The loop comprises a pair of pipe run elbows, a pair of flexible tube members, a pair of loop elbows, and a third flexible tube member. The pipe run elbows are oppositely disposed, and each has a first open end to be connected to the pipe run, and a second open end. The pair of flexible tube members each have first and second open ends. The first open ends of the tube members are connected to the second open ends of the pipe run elbows, respectively. The loop elbows are disposed in a spaced-apart opposing relation, and each has first and second open ends. The first open ends of the loop elbows are connected to the second open ends of the pair of tube members, respectively. Finally, the third flexible tube member is connected between, and to the second open ends of, the loop elbows.Type: GrantFiled: September 10, 1997Date of Patent: September 8, 1998Assignee: Flex-Hose Company, Inc.Inventors: Philip B. Argersinger, Robert J. Walsh
