Patent number: 4655433Abstract: A tensioner (10) is disclosed for use in tensioning connecting lines (16) connecting a marine riser (14) to a floating platform (12). The tensioner (10) is a passive system which incorporates a series of cylindrical elastomeric members (42, 54, 60) which are deformed in torsion to exert the proper tension on the connecting line (16). A specially tapered drum (30) is provided on the tensioner so that the radial distance from the axis of rotation of the drum to the position where the line leaves the drum varies to compensate for the variation in torsional moment of the elastomeric members so that a predetermined tension can be maintained on the line (16) as the line is payed out and taken in from the tapered drum.Type: GrantFiled: August 20, 1985Date of Patent: April 7, 1987Assignee: Lockheed CorporationInventors: George W. Peppel, Paul E. Sullivan

Patent number: 4515399Abstract: A housing (110) defines an enlarged central bore (162), from which protrudes a multi-conduit nipple (126). An elastomeric seal (128) flexibly joins the inner end of the nipple to the outer end of a respective sliding seat (116), the inner end of the seat being adapted to slide longitudinally within the central bore, whereby the elastomeric seal located is subjected to a shearing action as the nipple is pivotally deflected relative to the housing. One or more piston disks (174, 176) extend across the enlarged central bore so as to define a series of individual pressure chambers (182, 184, 186). A plurality of hollow cylindrical sleeves (188) extend through the disks, with the interior of each sleeve functioning as a continuation of a respective conduit through the connector.Type: GrantFiled: December 27, 1982Date of Patent: May 7, 1985Assignee: Lockheed CorporationInventors: Paul E.

Patent number: 4103939Abstract: A multi-channel flexible connector for connecting multiple parallel conduits for relative angular deflection between input and output conduits. In a more specific aspect, offshore well pipes are connected to a surface unit as they extend upward from the ocean floor to accommodate motion of the surface unit. An annular cup-shaped housing with a central cavity and bottom ports therein is adapted to be joined to input pipes. A nipple having a downfacing and flared lower end is adapted to be joined to output pipes and is positioned in the housing cavity. An elastomeric body includes an assembly of concentric spherical rings radially spaced apart by elastomeric pads. The elastomeric body is adhered to the inner and outer surfaces of the flared end of the nipple, to the lower surface of a collar mounted in sealed relation with the inner surface of the housing and to the upper surface of a seat mounted in the bottom of the housing cavity thereby to define a main flow channel through the connector.Type: GrantFiled: June 15, 1976Date of Patent: August 1, 1978Assignee: Murdock Machine & Engineering CompanyInventors: John T.

Patent number: 4098527Abstract: A flexible tension bearing connector includes a cylinder having a base portion supporting a central rigid spacer therein having an outer spherical surface facing away from the base portion and a center of curvature at the axis of the cylinder. A nipple has an internal spherically shaped surface contiguous to the spacer in a mating relation. An elastomeric bearing has an end inner ring which has a cylindrical center bore to receive the nipple and an end outer ring captured inside the cylinder. An intermediate elastomeric section has spherical geometry centered at the center of curvature of the spacer. The bearing encircles the nipple with annular planar bearing surface facing away from the spaces in a plane normal to the cylinder axis. A stop on the nipple contacts the annular planar bearing surface to transfer through the bearing to the cylinder any forces which would urge the bearing away from the spacer.Type: GrantFiled: January 21, 1977Date of Patent: July 4, 1978Assignee: Murdock Machine & Engineering CompanyInventors: John T.
