Title: Dynamic damper for use in a drill string
Inventor: HAUGHOM PER OLAV
IPC: E21B17/07
Filed: 2003-04-14
Abstract: A dynamic damper for installation in a drill string (1), the purpose of which damper is to reduce the risk of jamming the drill bit (5), thereby avoiding damages in the event of unwanted extreme oscillations and rotational speed of the drill string caused by uncontrolled release of torsional energy in the drill string when the drill string suddenly breaks free of the jam. For this purpose, the damper is constructed from an outer and an inner string section (11) and (12), supported concentrically and interconnected through a helical threaded connection (10), so that relative rotation between the sections caused by torque (8) will give an axial movement that lifts and loosens the drill bit from the bottom of the hole in critical jamming situations. The spring (9) maintains the outer string section in an axial position against the shoulder (22). A hydraulic damping effect on the axial movements is achieved by oil volumes (16) and (17) being interconnected through narrow bores (18).  Logging of the damping function is carried out by sensor (20), which registers and stores data to be read when the damper is retrieved to the surface.

Title: Production of propylene from steam cracking of hydrocarbons, particularly ethane
Inventor: SUMNER CHARLES
IPC: C07C11/06
Filed: 2004-11-15
Abstract: An ethane or other hydrocarbon feedstock is steam cracked to produce an ethylene stream which is processed in an ethylene plant recovery section to separate an ethane recycle and a polymer grade or chemical grade ethylene product stream. A portion of the ethylene product stream may then be reacted by dimerization to produce a butene stream. These formed butenes and/or butenes recovered from other sources and another portion of the ethylene product stream are reacted by metathesis to produce a propylene stream which is deethanized and separated from heavier hydrocarbons to produce the propylene product. The butene product stream may also be deethanized and is separated from heavier hydrocarbons. The overhead from the metathesis section deethanizer may be recycled to the ethylene plant recovery section. The reflux for the metathesis section deethanizer may be generated from the overhead or may be a portion of the ethylene product stream.

Title: Reorganization and repair of an icf catalog while open and in-use in a digital data storage system
Inventor: PACE RICHARD G
IPC: G06F17/30
Filed: 2005-02-18
Abstract: MVS mainframe computer systems employ the ICF (Integrated Catalog Facility) catalog environment to manage numerous data sets. To provide 24x7 availability of those data sets, the BCS (250,270) must be re-organized while leaving the catalog open to access by applications. To perform a re-org while open, a data CI correlation table (500) is constructed (314) and used to lay the data CIs into a backup file in logical order (316), so that they can be loaded into the new BCS (324) without sorting, thereby reducing downtime. Additionally, if the BCS is damaged during normal operation, repair of the structure must also be performed to ensure that correct access is maintained to all data that is cataloged in the BCS. Throughout the re-org process, structural integrity checks are performed on the data and index component of the BCS, and if errors are encountered, they can be repaired.
