Abstract: An optical fiber cable, includes at least one optical fiber and a cable connector at a cable end, and a removable cap removably couplable to a free end of the cable connector. The cap includes a recess adapted to receive and accommodate an anchor element of a cable pulling rope, and to retain the anchor element against traction when the pulling rope is tractioned.

Abstract: Disclosed herein is a shape optimized header comprising a shell that is operative for collecting a fluid; wherein an internal diameter and/or a wall thickness of the shell vary with a change in pressure and/or a change in a fluid flow rate in the shell; and tubes; wherein the tubes are in communication with the shell and are operative to transfer fluid into the shell. Disclosed herein is a method comprising fixedly attaching tubes to a shell; wherein the shell is operative for collecting a fluid; wherein an internal diameter and/or a wall thickness of the shell vary with a change in pressure and/or a change in a fluid flow rate in the shell; and wherein the tubes are in communication with the shell and are operative to transfer fluid into the shell.

Abstract: Managing a log-full condition of a transaction log in a transaction processing system, where the transaction log has a plurality of log records each associated with a particular transaction. When a log-full condition is detected, the active transaction having the oldest log entry of all active transactions is identified and logging for all transactions except for the identified transaction is temporarily suspended. A dynamic transaction backout of the identified transaction is initiated, with the writing of a backout record for the identified transaction to the log being delayed. Confirmation that the backout has completed is awaited before trimming the log. Then the delayed backout record for the identified transaction is written to the log, and normal logging is resumed.

Abstract: A method of preparing a wellbore for production includes running a wellbore clean-out string, including a cement evaluation tool and a wellbore cleaning tool, into a wellbore, acquiring data relating to at least one property of a cement bond of the wellbore, using the cement evaluation tool, and simultaneously cleaning the wellbore, using the wellbore cleaning tool, as the clean-out string is run into the wellbore in order to acquire first and second sets of data while running the string into the wellbore. The first and second sets are combined to form first and second logs of cement bond, which are used to produce an enhanced log of the cement bond.

Abstract: A firearm attachable bullet trap for use on a gas operated firearm having a compensator attached to the barrel. The bullet trap captures bullets from live rounds and provides an visual and tactile indication of live rounds having been fired. The bullet trap is designed for the shooting of blank rounds, but is adapted to handle live rounds having a bullet in a semi-automatic or automatic firearm.

Abstract: A method for installing an optical fibre unit in a protective tube housing a pulling rope includes the steps of: providing a mini tube having a longitudinal opening from end to end; transversally inserting a portion of the pulling rope in the longitudinal opening; contacting the pulling rope and optical fibre unit over a predetermined length; slipping the mini tube over at least a portion of the contacting length of the pulling rope and optical fibre unit; crimping the mini tube around the pulling rope and optical fibre unit; and drawing the optical fibre unit through the protective tube by pulling the pulling rope.

Abstract: A harrow includes plural hydraulic actuators to displace respective working elements between opposing first and second positions. The actuators are connected in series in a phasing relationship to define one or more hydraulic circuits. Each circuit includes a lead actuator mounted in a first orientation to displace the respective working elements in a first direction when extended and a secondary actuator in series with the lead actuator in an opposing second orientation to displace the respective working elements in the first direction when retracted. One of the ports of the secondary actuator is coupled to the same one of the ports of the lead actuator such that all of the working elements are simultaneously displaced in a common direction when supplying hydraulic fluid under pressure to the lead actuator. Additional actuators may be similarly connected in series in alternating orientations with the lead and secondary actuators of each circuit.
