Abstract: A threaded connection includes a pin member comprising a first pin step and a second pin step, and pin wedge threads disposed on each of the first and second pin steps and a box member comprising a first box step and a second box step, and box wedge threads disposed on each of the first and second box steps, wherein an axial separation of the first and second pin steps differs from an axial separation of the first and second box steps.

Abstract: A method of determining whether particular data is included in a data store. The particular data comprises a plurality of first data values and the data store comprises a plurality of second data values. The method comprises obtaining identification data associated with the particular data. The identification comprises a subset of said first data values. A portion of the data store is retrieved and it is determined whether at least a predetermined number of data values of the identification data have a predetermined relationship with corresponding second data values of the retrieved portion of the data store.

Abstract: Systems and methods for mitigating failure mode effects in a steer-by-wire system. The system includes a controller configured to alter a direction of the vehicle when the controller is in a failure mode. A steering device is coupled to a detector. The detector is configured to detect a steering input from a driver and output a signal representative of the steering input. A first actuator is coupled to a first control device. The first control device is configured to generate a first control signal representative of the steering input when the controller is in the failure mode. The first actuator alters the direction of the vehicle by removing energy from the vehicle. A second actuator is coupled to a second control device. The second control device is configured to generate a second control signal representative of the steering input when the controller is in the failure mode. The second actuator alters the direction of the vehicle by adding energy to the vehicle.

Abstract: A tubular connection includes a pin member having external wedge threads configured to engage a box member having corresponding internal wedge threads, and a solid lubricant coating applied on at least one of the internal and external wedge threads wherein the solid lubricant coating comprises a first uniform layer of a dry corrosion inhibiting coating made of an epoxy resin containing particles of zinc and a second uniform layer of a dry lubricant coating covering the first uniform layer.

Abstract: A process for separating Co from Ni in an aqueous solution comprises subjecting the solution to extraction and using kinetic differences between Ni and Co in the extraction for achieving at least a partial separation of Co from Ni. This is effected by controlling the duration of the extraction so that a major portion of Co and a minor portion of Ni is extracted from the solution to produce a loaded extractant, enriched in Co and depleted in Ni compared to the feed solution, and a Co-depleted raffinate containing Ni. In a further embodiment, the invention utilizes kinetic differences between Ni and Co during striping for effecting separation of Ni and Co. The loaded extractant can be subjected to a bulk stripping or a selective stripping operation to obtain Co and Ni solutions from which Ni and Co can be recovered. The process may be incorporated in a hydrometallurgical process for the extraction of Ni and/or Co from an ore or concentrate containing Ni and Co.

Abstract: Described herein are iron golf club heads and sets of iron golf clubs that have variable weight distribution. Each iron golf club head has a cavity and a y-shaped cavity pad disposed on at least a portion of a back wall of the cavity. The y-shaped cavity pad provide reduced vibrations within the cavity when the iron golf club head strikes a golf ball. The y-shaped cavity pad also provides an enlarged sweet spot to provide increased forgiveness for off-center hits. Other aspects, features, and embodiments are also claimed and described.

Abstract: A golf club head of the wood-type, including: a body defining an interior cavity and including a ball-striking face, a sole, a crown, and a ribbon extending rearwardly from the face; an elongated groove that extends along a portion of the ribbon; a weight slidably disposed in the elongated grove; and a fastener affixed to the weight capable of selectively fixing a location of the weight. Other aspects, features, and embodiments are also claimed and described.

Abstract: A threaded pipe connection includes a pin member having an external thread increasing in width in one direction, a box member having an internal thread increasing in width in an opposite direction so that complementary internal and external threads move into engagement upon make-up of the connection, and at least one contact zone in which the pin member and box member are in sealed contact.
