  • Patent number: 9593910
    Abstract: Firearm sight tools for removing and installing firearm sights are presented, the firearm sight tools including: a clamping assembly for clamping a firearm slide: a dovetail sight removal and installation assembly removably coupled with the clamping assembly for removing and installing a dovetail sight for the firearm slide; and a front sight staking assembly removably coupled with the clamping assembly for staking a front sight for the firearm slide. In some embodiments, the clamping assembly further includes: a pair of side plates for providing clamping surface, where the pair of side plates are substantially parallel with one another; a number of clamping bolts for providing a clamping force for the pair of side plates; and a cutout positioned along a top edge of each of the pair of side plates, the cutout provided for locating the dovetail sight removal and installation assembly.

  • Patent number: 6595287
    Abstract: A programmable controller for operating an artificial lift well is provided to monitor and operate a variety of analog and digital devices. An on-cycle of the well is initiated based on a pressure differential measured between a casing pressure and a sales line pressure. When a predetermined ON pressure differential is observed, the controller initiates the on-cycle and open a motor valve to permit fluid and gas accumulated in the tubing to eurged out of the well. Thereafter, the controller initiates a mandatory flow period and maintains the motor valve open for a period of time. The valve remains open as the system transitions into the sales time period. During sales time, the controller monitors the gas flow through an orifice disposed in the sales line. A differential pressure transducer is used to measure a pressure differential across the orifice. When the measure pressure differential is less than or equal to a predetermined OFF pressure differential, the controller initiates the off cycle.

  • Publication number: 20020074118
    Abstract: The present invention generally relates to an automated method and apparatus for operating an artificial lift well. In one aspect of the present invention, a programmable controller monitors and operates a variety of analog and digital devices. An on-cycle of the well is initiated based on a pressure differential measured between a casing pressure and a sales line pressure. When a predetermined ON pressure differential is observed, the controller initiates the on-cycle and open a motor valve to permit fluid and gas accumulated in the tubing to be urged out of the well. Thereafter, the controller initiates a mandatory flow period and maintains the motor valve open for a period of time. The valve remains open as the system transitions into the sales time period. During sales time, the controller monitors the gas flow through an orifice disposed in the sales line. A differential pressure transducer is used to measure a pressure differential across the orifice.
