  • Patent number: 11753245
    Abstract: A pharmaceutical container holder for holding pharmaceutical containers includes a receiver having an interior sized and shaped to receive and hold the pharmaceutical containers as a stack of pharmaceutical containers. The receiver has a removal location from which the pharmaceutical containers are removed from the receiver. A lift raises the pharmaceutical containers disposed in the interior of the receiver upward to move the pharmaceutical containers toward the removal location. A lift controller operates the lift to move the pharmaceutical containers upward toward the removal location after an upper-most pharmaceutical container of the stack of pharmaceutical containers has been removed from the removal location to move a subsequent upper-most pharmaceutical container of the stack of pharmaceutical containers to the removal location.

  • Publication number: 20160238704
    Abstract: Satellite geodesy can identify fault-related surface deformation above onshore oil and gas fields through the use of radar interferometry (InSAR). The method provides an independent and cost-effective approach to identifying faults and damage zones that can be associated with increased reservoir performance beyond traditional tools of subsurface imaging and reservoir evaluation.

  • Patent number: 5083546
    Abstract: A two-stage high flow purge valve for an evaporative emission system of a vehicle. The valve body contains two valves for controlling fluid flow through separate parallel flow paths in the valve body. A fast-acting, pulse width modulated solenoid valve responsive to an electrical control signal from the engine control computer precisely controls flow through a low flow path, and a vacuum-responsive valve controls flow through a high flow path in accordance with the level of manifold vacuum at the engine intake. A third valve member is provided to block flow through the high flow path when the engine is off and the manifold vacuum is zero. Means for calibrating both the solenoid valve and the vacuum-responsive valves are also provided.

  • Patent number: 5080565
    Abstract: The present invention is a retainer for a piston and valve subassembly of a scotch yoke compressor and a method of assembling it. The subassembly is comprised of a piston head, a suction valve, a spacer, a stop washer, and a rod held together by a retainer. The suction valve is assembled on the rod, then the rod is inserted into the piston head. Next the retainer is installed on an end of the rod for frictionally engaging the piston and rod, thus axially securing the suction valve and the rest of the piston head subassembly during assembly to the yoke.

  • Patent number: 5065979
    Abstract: A vacuum regulator for automotive vehicles of the type having a computer-controlled exhaust gas recirculation (EGR) system. The regulator controls the vacuum signal provided to the EGR valve in accordance with the current signal supplied to the regulator by the engine control computer. The vacuum regulator includes a solenoid structure having a secondary air gap in the flux path of the solenoid at the opposite end of the pole piece from the armature. The flux path across the secondary air gap is divided into a first fixed portion and second adjustable portion that is set during calibration of the regulator. The sensitivity of the calibration process is therefore substantially reduced, thereby enabling more accurate settings with less chance of overshooting the desired set point.

  • Patent number: 5013198
    Abstract: An air-hydraulic pump incorporates a primary pumping mechanism for supplying a first level of fluid pressure to a work-performing tool at a first flow rate in response to a supply of pressurized air. An auxiliary pumping mechanism is provided for delivering a second level of hydraulic fluid pressure less than the first level at a flow rate greater than the first flow rate. The auxiliary pumping mechanism provides sufficient pressure to overcome a load on the system up to a predetermined level, after which the auxiliary pumping mechanism ceases operation due to such load and the primary pumping mechanism delivers fluid pressure to the system sufficient to overcome the load. The auxiliary pumping mechanism speeds up operation of the work-performing tool for providing time-saving operation thereof.

  • Patent number: 4605197
    Abstract: A proportional pressure control device having a motor with a housing and a reciprocably movable armature oriented in the housing for movement between first and second limit positions. A valve body is secured to the motor housing. A platelike poppet valve member is secured to the armature on at least one end thereof. The valve body has a fluid pressure port thereon and it extends into the interior of the valve body to a chamber. A flow restrictor device is provided in the pressure port to restrict fluid flow from an external pressure source into the pressure port and the chamber. A nozzle outlet structure is provided in the chamber and has an annular flat valve seat thereon directly opposing the poppet valve member. The spacing between the valve seat and the poppet valve member effects a controlling of the magnitude of the fluid pressure developed in the chamber.

  • Patent number: 3976207
    Abstract: Apparatus for stabbing casing pipe as the casing is being run into a well bore. It includes a casing handling head arranged for grasping a generally upright section of casing pipe near the upper end thereof. The head is controllable for movement in a horizontal plane extending over the well bore and is movable vertically also. An operator platform is attached to the head for movement therewith. The platform has control means mounted thereon for operating the head, whereby an operator supported on the platform can visually observe and guide stabbing of a section of casing pipe and release the same by operating the control means. The position of the platform is such that an operator supported thereon can carry out other manipulative steps associated with the casing stabbing operation, as for example, the operation of the elevators, the pipe slings, and the like.
