摘要： An improved method and apparatus are provided for constructing and operating a linear actuator, and equipment incorporating a linear actuator, by operatively connecting a pressure biasing pneumatic arrangement between the driving member and the driven member of a mechanical linear actuator for applying a unidirectional biasing force between the driving and driven members, along an axis of motion, regardless of the location or movement of the driving and driven elements with respect to one another along the axis of motion. The pneumatic biasing arrangement is also configured, connected and operated to reduce the force which must be exerted by the driving and driven members in extending and retracting the linear actuator. The pneumatic biasing arrangement may further be configured for preferentially aiding extension or retraction of the actuator.

摘要： A dual component density sampler determines at least one of a density of water and a density of oil in a mixture of oil and water extracted from an oil well during production. A three-way valve is coupled to the oil well, with the three-way valve having a first output port and second output port. A dual-in-single-out manifold is coupled to the first output port. A segregation tank separates the water and oil, and has an entrance tank and exit tank. An entrance of the entrance tank is coupled to the second output port, and an exit of the entrance tank is coupled to an entrance end of the exit tank. An exit end of the exit tank is coupled to the dual-in-single-out manifold. A coriolis meter is coupled to the dual-in-single-out manifold, and is configured to selectively measure a density of the fluid mixture, the oil, and the water.

摘要： A method for operating a linear rod pump to pump fluids, such as water and/or hydrocarbons, from a subterranean formation or reservoir, include a linear rod pump having a mechanical rack and pinion drive arrangement, adapted for attachment to a pumping mechanism, such as the polished rod at the top of a rod string in a hydrocarbon well. The rack gear, of the rack and pinion drive arrangement, is adapted for connection to, and movement with, the polished rod. The pinion gear does not translate with the rack gear, and is driven by a reversible motor for affecting up and down reciprocating motion of the rack gear and pumping mechanism. Some forms of the invention include a compressible gas counter-balance arrangement. Some forms of the invention include an electronic drive configured for dealing with electric power generated by the motor during a portion of the pumping cycle.
