Patent CA-2834693-C (CA)
Inventor: CROW STEPHEN L
IPC: E21B23/01

Abstract: A cut and pull spear is configured to obtain multiple grips in a tubular to be cut under tension. The slips are set mechanically with the aid of drag blocks to hold a portion of the assembly while a mandrel is manipulated. An annular seal is set in conjunction with the slips to provide well control during the cut. An internal bypass around the seal can be in the open position to allow circulation during the cut. The bypass can be closed to control a well kick with mechanical manipulation as the seal remains set. If the tubular will not release after an initial cut, the spear can be triggered to release and be reset at another location. The mandrel is open to circulation while the slips and seal are set and the cut is being made. Cuttings are filtered before entering the bypass to keep the cuttings out of the blowout preventers.

Title: Hand-actuated device for remote manipulation of a grasping tool
Inventor: DANITZ DAVID J
IPC: B25J1/00
Filed: 2005-09-19
Granted: 2016-08-02
Abstract: The invention provides an articulating mechanism useful, for example, for remote manipulation of various surgical instruments and diagnostic tools within, or to, regions of the body. Movement of segments (A1, B1,D1) at the proximal end (106, 107, 121, 606, 1711, 1801) of the mechanism results in a corresponding, relative movement of segments (A2, B2, D2) at the distal end (108, 109, 123, 604, 808, 1721, 1822) of the mechanism. The proximal and distal segments are connected by a set of cables (104) in such a fashion that each proximal segment forms a discrete pair with a distal segment. This configuration allows such segment pair to move independently of one another and also permits the articulating mechanism to undergo complex movements and adopt complex configurations. The articulating mechanisms may also be combined in such a way to remotely mimic finger movements for manipulation of an object or body tissue.

Abstract: A method and assembly to produce data pulses in a drilling fluid in a drill string. The assembly comprises a shear valve that includes a valve member mounted in a valve passage in fluid flow communication with a fluid flow conduit of a drill string to which the assembly is connectable. The valve member is connected to a reciprocation mechanism comprising a rocker, a driven crank arrangement, and a slider member that provides a sliding coupling between the crank arrangement and the rocker. The slider member is pivotally connected to the crank arrangement, is keyed to the rocker for angular displacement about a valve axis, and is radially slidable relative to the rocker, so actuation of the crank arrangement causes angular reciprocation of the rocker, and hence of the valve member, about the valve axis, to produce data pulses in the drilling fluid.

Abstract: In a surface mining operation, real-time ore composition analysis can be used to direct ongoing mining processes, and in blending ore feed streams to achieve a blended dry ore stream that meets operational specifications for downstream processing. Further, the analysis data can be used to control downstream processing steps, for example in determining appropriate volumes and temperature of water and chemicals added to the ore to form a suitable slurry composition for efficient operation of a downstream hydrocarbon extraction process, or to optimize specific processing steps in the extraction of hydrocarbons from oil sands ore, based on the analysis data. The ore analysis data can also be used to update a mine or reservoir map. Ore analysis can be accomplished by infrared reflectance analysis using NIR probes installed on ore transport or processing equipment that come into direct contact with the ore to be analyzed.
