摘要： A piston head assembly (10) for reciprocating in a cylinder (12), a gap (25) between the piston and the cylinder being such that the difference in diameters is less than 0.010 inches. The piston includes a flange (11) on which a seal (22) made of polyurethane with a hardness of at least 80 Shore A is removably mounted. The seal includes a lip (24) extending beyond the diameter of the cylinder wall and a heel (23). A bulge (23a) is formed on the heel (23) when the seal is formed in orer to prevent slight depressions from forming around the heel when the seal cools.

摘要： A pipe handling system comprises a pipe erector (400) that is operable to move a pipe from a horizontal storage position to an inclined position. In the inclined position, an upper end of the pipe is adjacent to an elevated drill floor (24) of a drilling rig (12) and the pipe is at an angle between horizontal and vertical. The pipe handling system also comprises a guide system (500) that is operable to engage the pipe and control lateral movement of the pipe as it is moved from being supported in the inclined position by the pipe erector to a vertical position supported by the drilling rig.

摘要： A winch system and methods for operating a winch system are disclosed. A wire (126) is spooled onto a drum (122) rotatably mounted to a shaft (206). A permanent magnet is mounted to the drum (122) such that, when an electric current is applied to a coiled winding mounted to the shaft (206), the drum (122) rotates about the shaft (206). The winch (120) comprises a first braking system that controls the rotation of the drum (122) about the shaft (206) by controlling the application of the electric current to the coiled winding. The winch (120) also comprises a second braking system (210) that mechanically engages the drum (122) so as to prevent the rotation of the drum (122) about the shaft (206). The winch (120) is used in conjunction with a control system that facilitates the use of the winch (120) with lifting and supporting personnel working in elevated environments.

摘要： An elevator (10) comprises a body (12) having a longitudinal axis therethrough. The body (12) is operable to at least partially surround and support a tubular member (100) aligned with the longitudinal axis. The body (12) has a longitudinal opening (34) that is sized so as to allow the tubular member (100) to pass therethrough. A door (16) is rotatable about the longitudinal axis of the body (12) and has a closed position wherein the tubular member (100) is retained within the body (12) and an opened position wherein the tubular member (100) can pass through the longitudinal opening (34).

摘要： Provided herein are a centrifuge assembly and method for gaining access to an accelerator. A centrifuge accelerator system is releasably mounted within a centrifuge assembly by a detachable connector, thereby providing accessibility to the accelerator. The centrifuge assembly includes a hollow bowl (52), a rotating conveyor (10), a drive shaft (20), and an accelerator (30). A series of detachable connectors (40,41) are used to mount the drive shaft (20) and accelerator (30) within the centrifuge assembly, providing a repeatable technique for gaining access to the accelerator (30) without damaging or destroying the rotating conveyor (10) or drive shaft (20). Mounting the accelerator (30) in a detachable, non-permanent manner renders the ability to repair or replace the accelerator (30) more efficient.

摘要： Methods and apparatus are disclosed for spooling a flexible member (14) onto a drum (12) with a spooler assembly (20). In certain embodiments, a spooler assembly (20) comprises a spooler arm (22) operable to guide a flexible member (14) onto a drum (12) rotating about a drum axis. A first actuator (23) moves the spooler arm (22) in a first direction that is parallel to the drum axis. The first actuator (23) operates in a first mode wherein the flexible member (14) is allowed to free movement in the first direction and a second mode wherein the first actuator controls the movement of the flexible member (14) in the first direction. The spooler assembly (20) may also comprise a second actuator (26) that moves the spooler arm (22) in a second direction that is perpendicular to the drum axis.

摘要： Apparatus and methods for applying radial compressive stress pre-loading to a cylinder liner (20) are disclosed. A cylinder housing (10) is attached to a pump, and a cylinder liner (20) is disposed within the cylinder housing (10). A fluid inlet (16) in fluid communication with an annular space (30) between the cylinder housing (10) and cylinder liner (20) is disposed on the cylinder housing (10). The annular space (30) is filled with pressurizing fluid through the fluid inlet (16), which creates radial compressive stress pre-loading on the cylinder liner (20).
