    • An irrigation pump for use in irrigating small fields or supplementing larger irrigation systems can also be used for portable water supply for emergency, military, or for underdeveloped countries. The pump system is designed to be light-weight and semi-portable and can be powered with a small engine or electric motor. The apparatus uses a down well impeller that is driven by a flexible vertical shaft and a vertical shaft motor drive or engine. The pump impeller incorporates its own thrust and journal bearings for the pump shaft. The bearings are water lubricated. The main drive shaft is flexible and elongated and is supported over its entire length with a flexible shaft guide sleeve. The flexible drive shaft is surrounded by a convoluted well pipe so that the drive shaft and the well pipe can be removed from the well casing bore as a unit and then coiled for storage. The drive shaft accepts couplings at each end and a seal at its upper end. The outlet fitting and flexible pipe with pump attached can be packaged around an engine that is bolted to the outlet fitting. A flange on the outlet fitting can be used to bolt the entire assembly of engine and outlet fitting to the well head at a well casing flange. That entire assembly of outlet fitting, engine (or motor), well pipe, drive shaft and impeller can be removed as a unit from the well casing by simply unbolting the outlet fitting from the casing.
    • 用于灌溉小田地或补充较大灌溉系统的灌溉泵也可用于紧急,军事或不发达国家的便携式供水。 泵系统设计重量轻,半便携,可用小型发动机或电动马达驱动。 该设备使用由柔性垂直轴和垂直轴电机驱动或发动机驱动的井下叶轮。 泵叶轮结合了自己的推力轴和轴心用于泵轴。 轴承是水润滑的。 主驱动轴是柔性和细长的,并通过柔性轴引导套被支撑在整个长度上。 柔性驱动轴由旋转的井管围绕,使得驱动轴和井管可以作为一个单元从井套管孔中移除,然后盘卷以便储存。 驱动轴在每个端部接受联轴器,并在其上端接受密封。 带有泵的出口配件和柔性管可以封装在螺栓连接到出口接头的发动机周围。 出口配件上的法兰可用于将发动机和出口接头的整个组件在井套管法兰上螺栓连接到井口。 出口配件,发动机(或电动机),井管,驱动轴和叶轮的整个组件可以通过从外壳上拆下出口接头而从井套中作为一个单元被移除。

    • A two-component foam spray gun is readily disassembled for cleaning. It includes a body (1) with reactant (12, 14) and purge gas (16) inlet ports. A moldable valve packing (32) inside the body has a tapered conical interior surface (142), and apertures which match the reactant ports. A valve/tip (40) has a conical outer surface (48) which mates with the valve packing (32). The valve/tip (40) is held in place by a moldable packing washer (34), held at non-constant pressure by a screw (36, 38). The interior of the valve/tip (40) houses a removable mixing chamber (50). The mixing chamber (50) has direct flow orifices (60) and an auxiliary flow path (58, 60) which ameliorate pressure surges. The spray gun can be disassembled for cleaning without disturbing the seal, by removing the valve/tip (40) to the rear, thereby breaking it free of the conical packing. Rotation of the valve/tip (40) relative to the body (1) shuts off the reactant flow, and starts the purge gas flow.
    • 双组分泡沫喷枪易于拆卸清洗。 它包括具有反应物(12,14)和吹扫气体(16)入口的主体(1)。 主体内的可模制阀芯填料(32)具有锥形锥形内表面(142)和与反应物端口匹配的孔。 阀/尖端(40)具有与阀包装(32)配合的锥形外表面(48)。 阀/尖端(40)通过可塑性填料垫圈(34)保持在适当的位置,通过螺钉(36,38)保持在非恒定压力。 阀/尖端(40)的内部容纳可拆卸的混合室(50)。 混合室(50)具有改善压力波动的直流流孔(60)和辅助流路(58,60)。 喷枪可拆卸清洁,不会干扰密封,通过将阀/末端(40)卸下到后部,从而使喷枪免于锥形包装。 阀/尖端(40)相对于主体(1)的旋转关闭反应物流,并启动净化气体流。

    • A respiratory mask is provided with an eye shield having a body portion which is releasably-secured to the mask, and a shield portion which shields the eyes of the wearer. The shield portion is self-supporting on the body portion and, hence, on the mask, and includes a sheet of transparent, eye-shielding, material which can be replaced if it becomes marked or damaged. The shield portion can be pivoted forwards, relative to the mask, so that it is removed from the line of vision of the wearer without affecting the respiratory protection provided by the mask. A valve arrangement in the body portion of the eye shield can divert air from the mask into the shield portion, to remove contaminants from the region around the eyes of the wearer.
