    • A portable core drill adapted for sampling dense mineral specimens or the like by urging a fluid cooled/lubricated tubular drill bit into a dense mineral mass from which a sample is to be extracted is comprised of a drive member for imparting a drilling-effective rotary motion to a tubular drill bit about a longitudinal drill axis and a spindle member for coupling the drill bit to the drive member, which spindle member includes a bit fastening member for receiving and retaining the drill bit concentrically in respect of the drill axis. The bit fastening member, in turn, is comprised of a bit-engaging collet member, received in a collet housing having tapered sidewalls and an end wall, and a rotatable compression member (i) for constricting the collet member about the outer sidewall of the drill bit at or near the proximal end thereof upon rotation and (ii) for engaging an element on the collet member and urging the collet member outwardly of the collet housing upon counter-rotation; whereby the drill bit may be operatively engaged with and disengaged from the bit fastening member by hand rotation and counter-rotation of the compression member, respectively.

    • The radially compact fluid compressor especially suitable for use in the distillation apparatus or other environments where space may be at a premium is disclosed herein. The compressor includes a power driven impeller and a compressor housing which surrounds the impeller and which together with the impeller defines a fluid collection chamber extending between the first upstream end and a second fluid exiting downstream end. This collection chamber progressively enlarges vertically from its upstream end to its fluid exiting downsteam end, whereby fluid passing through the collection chamber from its upstream end to its downstream end progressively decreases in velocity and therefore progressively increases in static pressure.
    • 本文公开了特别适用于蒸馏设备或空间可能溢价的其它环境的径向致密流体压缩机。 压缩机包括动力驱动叶轮和围绕叶轮的压缩机壳体,并且其与叶轮一起限定在第一上游端和离开下游端的第二流体之间延伸的流体收集室。 该收集室从其上游端逐渐扩大到其流出下游端的流体,由此通过收集室从其上游端到下游端的流体逐渐降低速度并因此逐渐增加静压。

    • A centrifugal type of pump, for example one used for compressing steam, is disclosed herein. This pump includes an impeller located within a pump housing and connected to a power driven shaft assembly extending through a cooperating opening in the housing from outside thereof so as to rotate with the shaft assembly about the axis of the shaft assembly relative to the housing, whereby to cause fluid in the housing, for example steam, to be centrifugally forced radially outward. The pump also includes a sealing arrangement for preventing the steam or other such fluid within the housing from escaping through the housing opening containing the shaft assembly. This sealing arrangement is designed to provide a continuous liquid seal extending circumferentially around an axial section of the shaft assembly within the housing opening and radially between the axial shaft section and housing druing operation of the pump, whereby to seal the opening against the passage of steam or other such fluid within the housing.
    • 本文公开了一种离心式泵,例如用于压缩蒸汽的泵。 该泵包括位于泵壳体内的叶轮,并连接到从其外部延伸穿过壳体中的配合开口的动力驱动轴组件,以便随着轴组件相对于壳体绕轴组件的轴线旋转,由此 使壳体中的流体例如蒸汽被径向向外离心强制。 泵还包括用于防止壳体内的蒸汽或其它这样的流体通过包含轴组件的壳体开口逸出的密封装置。 该密封装置被设计成提供连续的液体密封件,该液体密封件围绕轴组件在壳体开口内的轴向部分周向延伸,并且径向地在轴向轴部分和泵的壳体排出操作之间,由此将开口密封抵靠蒸汽通道 或其它这样的流体。
