Abstract: The present invention is directed to producing fluid from an oil or gas well by means of a combination intermittently filled down hole chamber accumulation device and a connected upper continuous gas lift flow system, separated by an inline one-way reverse flow check valve. A two-way purge and vent valve controls the distribution of high pressure gas. The two-way valve first injects high pressure gas into the chamber accumulation device to displace the fluid from the chamber into the continuous flow conduit. The two-way valve then vents the residual high pressure gas from the chamber into a separate low pressure conduit to the surface. The valve also provides high pressure gas to the continuous flow conduit to assist in the production of the fluid.

Abstract: A method of increasing efficiency and avoiding or reducing potential stall conditions is accomplished by configuring a ripper of a track type tractor responsive to a net force vector acting on the ripper. The net force vector is indicative of the various forces and pressures acting on the ripper, and the values indicative of these forces can be sensed. For instance, the force and value indicative of the force magnitude can be sensed by monitoring driveline torque, whereas the force vector angle can be derived from ripper tilt and lift actuator pressures. The ripper is configured responsive to the force vector magnitude and direction either via a control algorithm, or by inputs generated by an operator.

Abstract: In response to a coasting drive instruction for measurement of a driving resistance of a hybrid vehicle, the coasting control procedure of the invention prohibits a change of a gear position in a transmission and stops both an engine and a motor MG1. The coasting control procedure calculates a canceling torque, which cancels out a torque applied to a ring gear shaft or a drive shaft via a power distribution integration mechanism by generation of an inertia torque accompanied with a rotation speed change of the motor MG1. The calculated canceling torque is set to a torque command Tm2* of a motor MG2, and the motor MG2 is driven and controlled with the torque command Tm2*. This arrangement makes the ring gear shaft or the drive shaft completely free and enables accurate measurement of the driving resistance of the hybrid vehicle during such a coasting drive of the hybrid vehicle in a fully non-driving state.
