20100300761 | APPARATUS AND METHODS TO OPTIMIZE FLUID FLOW AND PERFORMANCE OF DOWNHOLE DRILLING EQUIPMENT - Sleeves, stabilizers and other well tools may be formed with fluid flow paths or channels extending through one or more blades disposed on the exterior portions of such well tools. The blades and associated fluid flow paths extending therethrough may allow optimum fluid flow rates and volumes to enhance lifting of formation cuttings and downhole debris along with cleaning exterior portions of the well tool and an associated rotary drill bit. Location, configuration, orientation and/or dimensions associated with such blades and associated fluid flow paths or channels may also be modified to provide an enlarged pad or contact surface on exterior portions of one or more blades while maintaining desired fluid flow rates and volumes over exterior portions of the well tool. Such pads or contact surfaces may have optimum surface areas for contacting adjacent portions of a wellbore during directional drilling of the wellbore. | 12-02-2010 |
20110203852 | Segmented Downhole Tool - A downhole tool includes a plurality of segments positioned on a core member. This construction is particularly suitable for sleeves, stabilizers and drill bit gage pads used in the formation of oil and gas wells. Worn or damaged segments can be replaced without the need for replacing the entire unit. The segments may include spiral vanes for directed fluid upwardly to the well head. | 08-25-2011 |

20100156002 | High-throughput asymmetric membrane - A microporous asymmetrical membrane formed of one or more layers wherein the “tight” side of the membrane has an “opened” face or otherwise highly-porous reticulated surface is described. The microporous asymmetrical membrane has high throughput and high flux, even when used for filtering viscous materials, such as serum or plasma. The membrane's surface can be formed by ablation or solvation, or in a two or more layered structure, through an appropriate selection of casting dopes. | 06-24-2010 |

20140090063 | SYSTEM AND METHOD FOR INHIBITING THE PROCESSING OF NEW CODE MODULES BY AN OUTDATED RUNTIME ENVIRONMENT - A system and method for inhibiting some code modules from being processed by an outdated runtime environment are disclosed. The system and method may operate to detect that a runtime environment installed on a computer system is outdated. New code modules that have not been previously processed by the runtime environment may be inhibited from being processed by the outdated runtime environment, while known code modules that have been previously processed may be allowed to continue being processed uninhibitedly by the outdated runtime environment. | 03-27-2014 |
