    • An upper shackle assembly for a steel pump jack for a wood pole includes a u-shaped shackle component to receive the wood pole. The assembly includes a crank handle that extends through the shackle component and engages the pole to lower the pump jack down the pole. The assembly includes a brake attached to the shackle component to engage with the pole if the crank handle fails. A method for installing a steel pump jack to a wood pole includes the steps of placing a u-shaped shackle component about the wood pole. There is the step of closing a brake with the shackle component to engage with the pole if a crank handle fails. There is the step of extending the crank handle through the shackle component to engage the pole. A steel pump jack.

    • An upright vacuum cleaner (A) includes an upright housing section (B) and a nozzle section (C). A cyclonic airflow dirt and dust separating chamber (54) is defined in said upright housing section. A suction source (E) pulls air and entrained dirt, dust, and other contaminants through a main suction opening (26) formed in the underside (24) of the nozzle and into the cyclonic airflow chamber (54). The cyclonic airflow chamber causes the suction airstream to travel in a cyclonic path such that the entrained contaminants are separated therefrom and deposited into a dirt container (52) that defines the lower portion of the chamber (54). A main filter element (11) filters residual contaminants from the suction airstream between the chamber and the suction source. The main filter element is preferably made from high-density polyethylene porous filter media. A final filter assembly (F) filters the section airstream discharged by the suction source to ensure that the air discharged into the atmosphere is contaminant free, including those contaminants introduced into the airstream by the suction source itself.
    • 立式吸尘器(A)包括立式收纳部分(B)和喷嘴部分(C)。 在所述直立的壳体部分中限定有旋风气流污垢和灰尘分离室(54)。 吸入源(E)通过形成在喷嘴的下侧(24)中的主吸入口(26)将空气和夹带的污垢,灰尘和其它污染物吸入气旋气流室(54)。 气旋气流室使得吸入气流在气旋路径中行进,使得夹带的污染物从其分离并沉积到限定室(54)的下部的污物容器(52)中。 主过滤器元件(11)从腔室和抽吸源之间的吸入空气流过滤掉残留污染物。 主过滤元件优选由高密度聚乙烯多孔过滤介质制成。 最后的过滤器组件(F)过滤由抽吸源排出的部分气流,以确保排放到大气中的空气不含污染物,包括由吸入源本身引入到空气流中的污染物。
