Patent number: 7798573Abstract: A chair includes a supporting frame and a seat portion which is foldable about a transverse fold to define a rearward portion behind the transverse fold and a forward portion, forward of the transverse fold. The seat portion is supported above the supporting frame by its rearward portion. The chair also includes a reclinable back portion and a recline mechanism with which the back portion is connected for reclining action of the back portion. The recline mechanism is operably linked to the rearward portion of the seat portion such that on reclining action of the back portion, the rearward portion is moved to increase in rearward tilt angle and to obtain a net increase in height above the supporting frame, with a consequent folding of the seat portion about the transverse fold line under the weight of the occupant.Type: GrantFiled: September 5, 2008Date of Patent: September 21, 2010Assignee: Formway Furniture LimitedInventors: Mark Rundle Pennington, Jon Leonard Fifield, Robert Bruce Stewart

Patent number: 6817667Abstract: A chair (10) includes a supporting frame (20,22) and a seat portion (14) which is foldable about a transverse fold to define a rearward portion behind the transverse fold and a forward portion, forward of the transverse fold. The seat portion (14) is supported above the supporting frame by its rearward portion. The chair (10) also includes a reclinable back portion (16) and a recline mechanism with which the back portion (16) is connected for reclining action of the back portion (16). The recline mechanism is operably linked to the rearward portion of the seat portion (14) such that on reclining action of the back portion (16), the rearward portion is moved to increase in rearward tilt angle and to obtain a net increase in height above the supporting frame (20,22), with a consequent folding of the seat portion about the transverse fold line under the weight (W) of the occupant.Type: GrantFiled: September 17, 2001Date of Patent: November 16, 2004Assignee: Formway Furniture LimitedInventors: Mark Rundle Pennington, Jon Leonard Fifield, Robert Bruce Stewart

Patent number: 6516506Abstract: A scrolled resilient sheet is installed against the inner surface of a fluid conduit using a carrier tool from which a resilient sheet having an average thickness more than 2 mm and an elastic or pseudoelastic recoverable strain of at least 0.6% is released so that the sheet expands with an expansion force which is sufficiently high to allow the sheet to press itself into place alongside the inner surface of the conduit and to remain in place after installation.Type: GrantFiled: February 9, 2001Date of Patent: February 11, 2003Assignee: Shell Oil CompanyInventors: Martin Donnelly, Wilhelmus Christianus Maria Lohbeck, Robert Bruce Stewart

Patent number: 6070671Abstract: A method is provided for creating zonal isolation between the exterior and interior of an uncased section of an underground well system which is located adjacent to a well section in which a well casing is present. The method includes inserting an expandable tubular through the existing well casing into an uncased section, such as a lateral branch, of the underground well system and subsequently expanding the expandable tubular such that the one end is pressed towards the wall of the uncased section of the well system and the outer surface of the other end is pressed against the inner surface of the well casing thereby creating an interference fit capable of achieving a shear bond and a hydraulic seal between the surrounding surfaces.Type: GrantFiled: August 3, 1998Date of Patent: June 6, 2000Assignee: Shell Oil CompanyInventors: Francis Alexander Cumming, Simon Lawrence Fisher, Robert Bruce Stewart

Patent number: 5667011Abstract: The invention relates to a method of creating a casing in a borehole formed in an underground formation. The method comprises the steps of (a) installing a tubular liner in the borehole, the liner being radially expandable in the borehole whereby the liner in its radially expanded position has a plurality of openings which are overlapping in the longitudinal direction of the liner, (b) radially expanding the liner in the borehole, and (c) either before or after step (b), installing a body of hardenable fluidic sealing material in the borehole so that the sealing material fills said openings and thereby substantially closes said openings. The sealing material is selected so as to harden in said openings and thereby to increase the compressive strength of the liner.Type: GrantFiled: January 16, 1996Date of Patent: September 16, 1997Assignee: Shell Oil CompanyInventors: Daljit Singh Gill, Wilhelmus Christianus Maria Lohbeck, Robert Bruce Stewart, Jacobus Petrus Maria Van Vliet
