    • A dual use fluid filtration tool to separate both solids and gas from a fluid. The fluid filtration tool is suspended from and connected to downhole equipment, such as a downhole submersible pump having a motor, which rotates a shaft. The tool includes a housing having a cylindrical wall with a plurality of perforations therethrough and m interior chamber therein. A removable cylindrical filter surrounds the interior chamber of the housing in order to filter solid particles. At least one centralizer bearing within the interior chamber of the housing centralizes the shaft which passes therethrough. The fluid in the interior chamber is radially induced in order to separate gas from fluid. The gas separated from the fluid is directed out of the chamber while the fluid remaining in the interior chamber is directed to the intake of the downhole pump.
    • 双重用途流体过滤工具,用于将固体和气体与流体分离。 流体过滤工具悬挂并连接到井下设备,例如具有旋转轴的电动机的井下潜水泵。 所述工具包括具有圆柱形壁的壳体,所述圆柱形壁具有穿过其中的多个穿孔和在其中的内部腔室。 可移除的圆柱形过滤器围绕壳体的内部腔室以便过滤固体颗粒。 在壳体的内部腔室内的至少一个扶正器轴承将通过其中的轴中心。 径向地引导内室中的流体,以将气体与流体分离。 从流体分离的气体被引导出室,而残留在内室中的流体被引导到井下泵的入口。

    • A weapon control system is disclosed which includes system electronics providing control and drive electronics for the weapon control system, a weapon mount for supporting and firing a weapon in accordance with commands from the system electronics, a remote control including a visual display and hand controls for operational control of the weapon control system from a position distant from said weapon mount, and a system disconnect for removal of control of the weapon from the weapon control system and for safety interlock to prevent accidental firing of the weapon. The weapon mount is adapted to support and fire a variety of weapons. A gyro stabilization assembly is mounted on the weapon mount and operatively connected to the remote control and the system electronics for allowing line-of-sight weapon and integral sight stabilization.

    • A switching circuit for conducting a pulse of current between a first and a second terminal, the circuit including a transistor having a base connected to the first terminal, an emitter and a collector and a saturable-core transformer having an emitter winding coupling the emitter to the first terminal and a collector winding coupling the second terminal to the collector so as to provide regenerative current feedback rapidly driving the transistor into saturation after the transistor is suitably triggered, the circuit diverting the collector current from the emitter to the base circuit sweeping carriers out of the base and hastening the transistor turn-off after the transformer core saturates decoupling the emitter and collector windings.
    • 一种用于在第一和第二端子之间传导电流脉冲的开关电路,所述电路包括具有连接到第一端子的基极的晶体管,发射极和集电极以及具有将发射极耦合到发射极的可饱和磁芯变压器, 第一端子和集电极绕组将第二端子耦合到集电极,以便在晶体管被适当地触发之后提供再生电流反馈,从而将晶体管迅速驱动到饱和状态,电路将集电极电流从发射极转移到基极电路将扫描载流子 的基极,并且在变压器芯饱和使发射极和集电极绕组去耦之后加速晶体管截止。
