20080239564 | Method and Apparatus for Controlling the Temperature of a Disk Drive During Manufacture - An apparatus for controlling the temperature of a disk drive during manufacture of the disk drive has a cell having a mounting arrangement to which a disk drive can be mounted and having walls defining a volume in which the disk drive is received when mounted to the mounting arrangement during manufacture of the disk drive. At least one wall of the cell adjacent said volume is heat conductive and is arranged such that a disk drive when received in the volume does not touch said at least one wall. An air-agitating device agitates air between the at least one wall and a disk drive when received in the volume to encourage heat transfer between said at least one wall and a disk drive when inserted into the volume. The air-agitating device is mounted so as to be vibrationally isolated from a said disk drive when mounted in the cell. | 10-02-2008 |
20090122443 | Disk Drive Carrier Assembly and Method - A disk drive carrier assembly for carrying plural disk drives is provided. The assembly has a casing having first and second opposed ends, opposed sides, a top and a bottom. Drive cards are provided in the casing. Each drive card has a disk drive receiving portion for receiving a disk drive and provides at least one of a power and a data connection to a disk drive. A baffle arrangement splits an air stream entering the casing at a first end of the casing to flow over the disk drive receiving portion of each of the drive cards. The drive cards and the baffle arrangement are arranged so that air flows only in parallel over the disk drive receiving portion of each of the drive cards. In this way, each disk drive receiving portion receives air that has not passed over another disk drive receiving portion of the assembly. | 05-14-2009 |

20150129242 | SEALING ANNULAR GAPS IN A WELL - A well tool for sealing against a wall of well includes an elongate mandrel. A seal assembly encircles the mandrel and can change between an unset state and an axially compressed set state. The seal assembly includes an annular elastomer seal element configured to radially deform into contact with the wall of the well in the set state. An annular anti-extrusion ring is included to compress the seal element and form a containing space with a garter spring embedded in the seal element. The garter spring is embedded in the seal element adjacent the axial end of the seal element and configured to span the gap between the anti-extrusion ring and the wall of the well in the set state. The containing space can prevent the seal element from excessive deformation. | 05-14-2015 |

20080302541 | Grooved Expandable Recess Shoe and Pipe for Deployment of Mechanical Positioning Devices - A first, expandable casing member, in an unexpanded state, is provided with a lower axial end that has a radially expanded upset or recess shoe and a locating profile. The first casing member is run into a wellbore, expanded, and secured in place within the wellbore. A second expandable casing member is then provided in an unexpanded state and disposed into the wellbore through the first casing member using a running tool. The second casing member is located with respect to the first casing member and expanded using an expansion member carried by the running tool. | 12-11-2008 |
20090032266 | One Trip Tubular Expansion and Recess Formation Apparatus and Method - A one trip top to bottom expansion to form a lower end recess on a tubular is described using two swages of different dimensions. The smaller swage is run down hole with the larger swage behind it in a locked collapsed position. When the proper depth is reached the leading swage hits a no go. A pickup force with dogs engaged in a groove releases the lock on the larger swage at which point applied pressure sets an anchor, extends the larger swage to take over the expansion for the recess at the lower end of the tubular. An emergency release is provided to pull out of the hole if the swage cannot complete the task. | 02-05-2009 |
20120133098 | ANTI-EXTRUSION BACKUP SYSTEM, PACKING ELEMENT SYSTEM HAVING BACKUP SYSTEM, AND METHOD - An antiextrusion backup system includes an inner expandable backup ring having a first set of slots. An outer expandable backup ring having a second set of slots wherein the outer expandable back up ring is rotationally locked to the inner expandable backup ring to prevent an extrusion gap in an expanded condition of the backup rings. A method for operating within a tubular is also included. | 05-31-2012 |

20090032261 | Valve - A downhole valve comprises a tubular body and a valve member. The valve member is normally closed and in the closed position may prevent or restrict passage of a working fluid through the body. The valve member is movable to an open position, a first working fluid pressure differential being necessary to move the valve member from the closed position and a lower second working fluid pressure differential being necessary to maintain the valve member in the open position. | 02-05-2009 |
20100212912 | Valve - A downhole valve comprises a tubular body and a valve member. The valve member is normally closed and in the closed position may prevent or restrict passage of a working fluid through the body. The valve member is movable to an open position, a first working fluid pressure differential being necessary to move the valve member from the closed position and a lower second working fluid pressure differential being necessary to maintain the valve member in the open position. | 08-26-2010 |

20150069752 | Modular Tubing Seal Bore System - A seal bore is provided in a modular form so that a desired length of continuous seal bore can be provided with modules that are preferably secured to each other with threads. The modular concept allows overall seal bore lengths to go beyond the 20 meter limit that previously existing that could be attained with honing equipment entering opposed ends of a tubular. The modules abut each other as the threaded connection is made up. A transition zone extends in opposed direction on opposed sides of a connection that retracts the contact location between modules far enough so that even if the dimensional tolerances all go to the extreme in the pin and box that make the connection, a surface irregularity will be sufficiently small as to avoid seal stack contact that can result in potential seal damage. The seal stack length spans the transition zone to preserve sealing integrity. | 03-12-2015 |
