| 20080211196 | Annular seal - An annular seal device includes a mandrel, at least one cone axially moveable on the mandrel, at least one sealing element having a frustoconical outer surface and a frustoconical inner surface, at least one contact feature at the at least one cone and operably engageable with the at least one sealing element, and at least one of a blocking element and a resilient member at the mandrel, the at least one of a blocking element and a resilient member supporting a blocking surface in opposition to the at least one contact feature. The resilient member itself includes a tubular body having spring rings at axial ends thereof, and a plurality of beams extending spirally from one axial end to the other axial end. | 09-04-2008 |
| 20080296028 | DOWNHOLE PRESSURE CHAMBER AND METHOD OF MAKING SAME - Disclosed herein is an atmospheric chamber. The atmospheric chamber includes, a first opposing wall of the chamber and a second opposing wall of the chamber, end members sealingly joining the first and second opposing walls of the chamber to create a fluid tight volumetric space, and at least one support substantially bridging between the first opposing wall and the second opposing wall positioned between respective end members. | 12-04-2008 |
| 20090044948 | Ball seat having ball support member - Apparatuses for restricting fluid flow through a well conduit comprise a housing having a longitudinal bore and a seat disposed within the bore. The seat has a first position when the apparatus is in the run-in position and a second position when the apparatus is in the set position. A plug element support member has a retracted position when the apparatus is in the run-in position and an extended position when the apparatus is in the set position. A plug element adapted to be disposed into the bore and landed on the seat to restrict fluid flow through the bore and the well conduit is used to move the plug element support member from the retracted position to the extended position, thereby providing support to the plug member landed on the seat. | 02-19-2009 |
| 20090066030 | ANNULAR SEAL - An annular seal device includes a mandrel, at least one cone axially moveable on the mandrel, at least one sealing element having a frustoconical outer surface and a frustoconical inner surface, at least one contact feature at the at least one cone and operably engageable with the at least one sealing element, and at least one of a blocking element and a resilient member at the mandrel, the at least one of a blocking element and a resilient member supporting a blocking surface in opposition to the at least one contact feature. The resilient member itself includes a tubular body having spring rings at axial ends thereof, and a plurality of beams extending spirally from one axial end to the other axial end. | 03-12-2009 |
| 20090159289 | Ball seat having segmented arcuate ball support member - Apparatuses for restricting fluid flow through a well conduit comprise a housing having a longitudinal bore and a seat disposed within the bore. The seat has a first position when the apparatus is in the run-in position and a second position when the apparatus is in the set position. The seat comprises an arcuate member comprising a plurality of slits defining a plurality of segment members having a gap there-between. Each of the gaps are variable such that movement of segment members inwardly causes the gaps to be narrowed or closed off completely when a plug element is disposed into the bore and landed on the arcuate member to move the arcuate member from the first position to the second position, causing restriction of fluid flow through the bore and the well conduit. | 06-25-2009 |
| 20090321081 | Controlled Pressure Equalization of Atmospheric Chambers - Methods and devices for equalizing an atmospheric chamber within a well tool in a controlled manner following the operation of setting the well tool. A packer setting tool is described having a setting mechanism with an atmospheric chamber and an equalization assembly to permit the pressure differential between the atmospheric chamber and the surrounding annulus to be substantially equalized. | 12-31-2009 |

| 20080275936 | Apparatus and methods for processing mailpiece information by an identification code server - Apparatus and methods consistent with the present invention provide for processing delivery item information in an identification code sorting system by an identification code server. In one embodiment, a primary identification code server receives an identification file containing identification information uniquely corresponding to a delivery item. In this embodiment, the primary identification code server processes the delivery item information and may send the identification file to a secondary identification code server. In another embodiment, a secondary identification code server receives an identification file from a primary identification code server and processes the delivery item information. | 11-06-2008 |
| 20080300717 | Apparatus and methods for processing mailpiece information by an identification code server - Apparatus and methods consistent with the present invention provide for processing delivery item information in an identification code sorting system by an identification code server. In one embodiment, a primary identification code server receives an identification file containing identification information uniquely corresponding to a delivery item. In this embodiment, the primary identification code server processes the delivery item information and may send the identification file to a secondary identification code server. In another embodiment, a secondary identification code server receives an identification file from a primary identification code server and processes the delivery item information. | 12-04-2008 |
| 20090046892 | Apparatus and methods for identifying and processing mail using an identification code - Apparatus and methods consistent with the present invention provide for identifying and processing mail using an identification code on a mailpiece as a redundant source of identification information in a mail sorting system. In one embodiment, this information is stored in a temporary database and used for the identification and processing of mail in a Remote Bar Code System (RBCS). In this embodiment, the identification code enables the automation of mail sorting and other processing tasks, reducing costs and delays in mail delivery services. In another embodiment, the identification and processing of mail occurs in an Identification Code Sorting (ICS) system. In this embodiment, a long-term database allows for mail sorting and other processing tasks on a national or global level. | 02-19-2009 |
| 20090173672 | Apparatus and methods for reading an identification code from a mailpiece - Apparatus and methods consistent with the present invention provide for reading an identification code from a mailpiece. In one embodiment, there are a reader unit and a reader head assembly connected by an optical cable, which provide for the identification of a mailpiece in an identification code sorting system. | 07-09-2009 |
