Abstract: A method for making a riser component includes: positioning a coupler adjacent and end of a tube such that a region of the coupler forms an interface with the tube's end, wherein the region includes a material (in some embodiments an aluminum alloy), and the tube's end includes a groove and another material (in some embodiments a steel alloy) that is different than the region's material; heating the region of the coupler to increase the region's malleability; and exerting pressure on the region of the coupler to plastically deform the region to insert some of the region's material into the groove in the tube's end. By fixing the coupler to the tube in this manner, the coupler may be strongly secured to the tube, and thus able to withstand high, dynamic loads frequently experienced in service. Also, the material of the coupler may be different than the material of the tube, and thus the material of the coupler may be lighter than the material of the tube.

Abstract: Systems and methods for performing replication operations on a continuous data protection system. In one embodiment, a method includes identifying at least a portion of the series of transactions on the continuous data protection system to be included in the pseudosnapshot, identifying an initial time at which the pseudosnapshot begins, identifying a final time at which the pseudosnapshot ends, identifying a last transaction before the final time at which the pseudosnapshot ends, and creating an event marker identifying a particular point in time that the last transaction was saved on the continuous data protection system.

Abstract: Systems and methods for performing scheduled backups and recovery of data generated by one or more production applications operating on a MAGIC platform located on two or more host computers in a coherency group. The data for a coherency group is stored in a primary storage in the form of one or more production volumes and ISB protocol is used to create one or more clone volumes. Exemplary methods for backing up one or more clone volumes for a coherency group to a backup storage include copying the one or more clone volumes to a backup storage or creating a snapshot of the one or more clone volumes. The ISB functions of splitting and/or reconnecting the one or more production volumes and one or more clone volumes occur at substantially the same time for all the two or more host computers in the coherency group.

Abstract: A method and system for performing multiple concurrent recovery operations using a single instance of a user interface. One exemplary method includes initiating a first recovery operation via a single user interface. The first recovery operation includes copying a first data object from a first backup storage location to a first recovery storage location. The exemplary method further includes initiating a second recovery operation via the single user interface without requiring a user to open a separate instance of the user interface. Similarly, the second recovery operation includes copying a second data object from a second backup storage location to a second recovery storage location. At least a portion of the second recovery operation occurs concurrently with at least a portion of the first recovery operation.

Abstract: A method and system for restoring data on a production server by recovering individual data objects from a recovery storage group to a database residing on the production server. In one example method, a recovery interface accesses a recovery storage group containing a recovered database. The recovered database has been recovered from a backup storage location and contains a copy of a database residing on the production server. The method then identifies each data object residing in the recovery storage group and displays each of the data objects on a graphical user interface configured to allow a user to select and individual data objects for recovery from the recovered database. The selected data objects are restored to the appropriate location on the production server.

Abstract: Systems and methods for performing replication operations on a continuous data protection system. Exemplary methods include identifying a series of transactions in a continuous data protection system, identifying an event marker indicating a point in time in the series of transactions, copying at least a portion of the series of transactions up until the point in time of the event marker from the continuous data protection system, and presenting the copy of at least a portion of the series of transactions such that the surfaced copy can be read in a subsequent replication operation.

Abstract: The present invention provides an improved structural assembly constructed of a plurality of structural members secured together. At least one of the plurality of structural members defines a first region characterized by comparatively high operational stress and a second region having a locally refined grain structure positioned such that the second region at least partially encompasses the first region to thereby enhance the strength, toughness and fatigue resistance of the at least one structural member in the first region. The present invention also provides a method for selectively improving the strength, toughness and fatigue resistance of a structural member in a region of high operational stress including the steps of casting the structural member in a pre-selected configuration. Regions of the structural member having comparatively high operational stress are identified. The structural member is secured to prevent movement.

Abstract: The present invention provides a backing device for backing up weld joints formed by friction stir welding workpieces having curvilinear geometries. The backing device includes a backing ring defining a contact zone. At least a portion of the contact zone defined by the backing ring engages the weld joint opposite the friction stir welding tool to thereby support the weld joint and to constrain the plasticized material within the weld joint. The backing device includes a restraining member in operable communication with the backing ring to urge the contact zone of the backing ring toward the weld joint. The backing device includes a sensor for measuring the magnitude of force exerted by the contact zone of the backing ring upon the weld joint.

Abstract: A backing member for a friction stir butt welding apparatus includes a groove in the working surface of the backing member which supports the workpieces being butt welded. The backing member is positioned with the groove aligned directly beneath the butt joint between the workpieces. A rotating friction stir welding pin is introduced at the joint so as to plasticize the material of the workpieces on either side of the joint, and pressure is applied between the stir pin and the workpieces to create a forging pressure which forces plasticized material downward through the root zone of the weld and into the groove in the backing member. A visible bead is thus produced on the lower surfaces of the workpieces indicating total penetration of the weld. Lack of a bead indicates probable failure of the weld to totally penetrate through the root zone.
