    • The present invention provides for an apparatus for use with a traveling valve assembly of a downhole pump for releasing gas and thereby breaking gas locks. The apparatus comprises a piston slidably disposed within a cylindrical housing, the piston being driven by an attached plunger element. On the down stroke of the pump, the piston protrudes through end of the cylindrical housing engaging and opening the adjacent valve. On the up stroke of the pump, the piston retracts into the cylindrical housing, disengaging from the valve allowing it to close. Fluid flows along the outer surface of the apparatus by means of fluid ports connected by defined fluid passages.
    • 本发明提供一种与用于释放气体并因此破坏气体锁的井下泵的行进阀组件一起使用的装置。 该装置包括可滑动地设置在圆柱形壳体内的活塞,活塞由附接的柱塞元件驱动。 在泵的下冲程中,活塞通过圆柱形壳体的端部突出地接合并打开相邻的阀。 在泵的上行程中,活塞缩回到圆柱形壳体中,与阀分离,允许其关闭。 流体通过由限定的流体通道连接的流体端口沿着装置的外表面流动。

    • An improved aqueous acidic trivalent chromium electrolyte and process for increasing the tolerance thereof to the presence of deleterious contaminating metal ions and organic impurities which normally progressively increase during commercial operation of the electrolyte ultimately resulting in chromium electrodeposits which are commercially unsatisfactory due to the presence of streaks, clouds, and hazes in the deposit. The improved composition contains an effective amount of at least one EDTA compound which is effective to mask the adverse effects of such contaminating metal and organic impurities and which also enhances the codeposition of such metal contaminants on the parts being plated thereby reducing, and in some instances, preventing the accumulation of such contaminating metal ions in the electrolyte.
