摘要： There is provided a wrench for a workpiece having a wrench head (26) with a fixed jaw element (44) and an adjustable jaw element (46) opposite the fixed jaw element, the fixed jaw element and the adjustable jaw element defining a workpiece engagement area that receives and engages the workpiece. The fixed jaw element and the adjustable jaw element are connected by a pin and slot connection (52, 50) that permits movement of the adjustable jaw element relative to the fixed jaw element to adjust the size of the workpiece engagement area. A removable die (42) is provided that engages the slot (50) to restrict the movement of the pin (52) along the slot (50) and define a maximum size of the workpiece engagement area. An articulated actuator (30) actuates the wrench head to apply torque to the workpiece.

摘要： A drill bit includes a bit head having a front face, a plurality of blades extending along at least a portion of the front face, the blades comprising cutters, a cavity for forming a core, the cavity being approximately centrally located in the front face of the bit between adjacent end portions of the plurality of blades, and a removable core breaking device disposed within the cavity. The core breaking device is configured to project toward the front face a distance to engage and destroy the so formed core into multiple smaller fragments prior to a core length exceeding a core diameter, or project toward the front face a distance to engage and break the so formed core into a substantially unitary core sample.

摘要： A tool includes a housing between an outer wail and an inner wall that surrounds a longitudinal tool bore. First and second axially spaced ports connect the housing to the tool bore. An unlocking piston seals across the first port and an arming sleeve seals across the second port. A locking ring is held in place by a retaining ring and prevents the arming sleeve from sliding towards the unlocking piston to open the second port. An unlocking tool bore pressure at the first port moves the unlocking piston axially to displace the retaining ring and unlock the tool. A lower, arming tool bore pressure moves the arming sleeve in the unlocked tool to open the second port, and arms the tool. An actuating tool bore pressure, which is less that the unlocking pressure, actuates a valve piston via the open second port.

摘要： A valve (30) has a valve body which includes a sub (31, 32). A bore (41) extends through the valve body and the sub. The valve also comprises a port (44) and a sleeve (34). The sleeve is mounted for hydraulic displacement. There is a passage through the sleeve which is in fluid communication with the bore. The sleeve is moveable in response to fluid pressure from the bore through the passage. The sleeve is moveable from a closed position, in which it restricts flow out of the bore through the port, to an open position, in which it allows flow out of the bore through the port.

摘要： Drill bits comprise a body having an uphole end and a downhole end. The uphole end is adapted for connection to a tool assembly for rotating the drill bit. The tool assembly has an axis of rotation. The downhole end has one or more cutting members adapted for removing material in contact with the downhole end when the drill bit is rotated. The body has an uphole major axis and a downhole major axis. The uphole axis and the downhole axis are offset from each other. The uphole axis is central to the uphole end and is aligned with the tool assembly axis of rotation. The uphole axis defines an axis of rotation for the drill bit. The downhole axis is central to the downhole end.

摘要： A plug apparatus comprises a wedge, a sealing ring, and a slip. The wedge comprises an axial wedge bore. A seat is defined in the wedge bore. The seat is adapted to receive a ball. The wedge has a tapered outer surface which decreases in diameter from the upper to the lower extent of the tapered outer surface. The sealing ring is received around the tapered outer surface of the wedge. The sealing ring has an axial ring bore and is radially expandable. The slip comprises an axial slip bore having a tapered inner surface. The tapered inner surface decreases in diameter from the upper to the lower extent of the tapered inner surface. The inner surface is adapted to receive the wedge. The wedge is adapted for displacement from an unset position generally above the slip to a set position wherein the wedge is received in the slip bore.
