Abstract: The present invention is a generally circular rotary seal that establishes sealing between relatively rotatable machine components for lubricant retention and environmental exclusion, and incorporates seal geometry that interacts with the lubricant during relative rotation to distribute a lubricant film within the dynamic sealing interface. The features of a variable inlet size, a variable dynamic lip flank slope, and a reduction in the magnitude and circumferentially oriented portion of the lubricant side interfacial contact pressure zone at the narrowest part of the lip, individually or in combination thereof, serve to maximize interfacial lubrication in severe operating conditions, and also serve to minimize lubricant shear area, seal torque, seal volume, and wear, while ensuring retrofitability into the seal grooves of existing equipment.

Abstract: The present invention provides a rapid rig-up and rig-down pipe stand building and racking system that is capable of being retrofit to an existing drilling rig. In particular, the invention relates to a horizontal to vertical pipe delivery machine that is mountable to a drilling rig. The horizontal to vertical machine delivers sections of pipe to a pair of drilling rig mounted elevators. The elevators receive and vertically translate the sections of pipe. A power tong may be used to make connections between the sections of pipe to form a pipe stand, and may also break the connections of the pipe stand. A drill floor mounted pipe racking system receives the connected drill pipe from the elevators. A pipe racking system that may be used in conjunction with the stand building system is capable of controlled, rapid, and precise movement of multiple connected sections of pipe.

Abstract: A hydrodynamically lubricated sealing element for applications where the pressure of a contained fluid can be significantly greater than the pressure of the seal lubricant. The sealing element retains the pressure of the contained fluid and provides hydrodynamic lubricant pumping activity at the dynamic sealing interface to enhance service life. The invention is particularly suitable for oilfield drilling swivel washpipe assemblies, downhole drilling tools, and rotary mining equipment, and for applications such as artificial lift pump stuffing box assemblies and centrifugal pumps where a rotating shaft penetrates a pressurized reservoir that is filled with abrasive-laden liquids, mixtures, or slurries.
