| 20090061229 | DIAMONDOID STABILIZED FINE-GRAINED METALS - Thermal stability of cryomilled Al+1% diamantane was investigated in the temperature range of 423 to 773K. Diamantane is a nanosized hydrocarbon molecule with a 14 carbon atom diamond cubic framework that is terminated by hydrogen atoms. Following the cryomilling of the Al powders and diamantane cages, the average grain size characterized using transmission electron microscopy (TEM) and X-ray diffraction (XRD). The as-cryomilled grain sized was found to be of the order of 22 nm, essentially the same as that for Al cryomilled without diamantane. To determine thermal stability, the powders were sealed in glass tubes in an Ar atmosphere to avoid oxidation and contamination and annealed at different temperatures between 423 and 773K for different holding times. Following these treatments, the grain size of cryomilled Al+1% diamantane was consistently less than that for cryomilled Al by about a factor of two. Preliminary investigations indicate that the grain growth exponent n decreased with increasing temperature, reaching a value of approximately 35 at 423 K. Such a high value of n suggests the operation of strong pinning forces on boundaries during annealing treatment. The thermal stability data were found to be consistent with Burke's model based on drag forces exerted by dispersion particles. | 03-05-2009 |

| 20110083857 | REPEATABLE, COMPRESSION SET DOWNHOLE BYPASS VALVE - A bypass valve for use in tubing string which can be repeatedly opened and closed to selectively provide bypass fluid flow between the interior of the tubing string and the annulus to assist in flowing debris. The valve uses hardened valve elements which can be opened and closed while flowing fluids under pressure through the tubing string. The valve is actuated by placing the tubing string in a sufficient weight down condition to operate the valve. A trigger is provided to prevent unintended actuation of the bypass valve during use. | 04-14-2011 |
| 20110203809 | WELLBORE BYPASS TOOL AND RELATED METHODS OF USE - Disclosed is a bypass tool for connection in a tubing string suspended in a subterranean location in a wellbore. The bypass tool has a tubular body for connection to a tubing string with ports in the body wall to inject fluid into the annulus, surrounding the tubing string. In some applications, nozzles are placed in the ports to create fluid jets which can be utilized, for example, for cleaning a subsea BOP. In other applications, fluids are injected into the annulus to assist circulation. An axially shiftable sleeve is mounted in the body's internal bore and acts as a valve to open and block flow through the ports. Spring-loaded detents in the body engage openings in the sleeve to lock the sleeve against axial movement. The detents extend into the sleeve to be engaged by an actuator ball pumped down the tubing string to the bypass tool. In operation, the bypass tool is run into the wellbore in the closed position with the sleeve closing the ports in the mandrel. When bypass flow is desired, an actuation ball is pumped down the wellbore to the bypass tool. The ball engages a seat in the sleeve to block flow down the tubing string. The ball also engages and depresses the detents, unlocking the sleeve to shift axially down the wellbore to the bypass position where ports in the sleeve align with ports in the mandrel to permit flow through the ports. To return the bypass tool to the closed position, a second ball of the same diameter as the first ball is pumped down the well to abut the first ball and engage and depress the detents to allow the sleeve to shift to a closed position. In this closed position, flow through the tubing string is reopened by shifting the ball-seat assembly to an enlarged area of the mandrel bore where fluid is free to flow around the ball seat. | 08-25-2011 |
