    • The present invention provides a means for producing a laminar output of fluid which is substantially turbulence free. The present invention utilizes an input tank or enclosure which includes turbulence reducing and flow straightening devices for producing a turbulent free output flow of water. This enclosure uses a tangential input port to introduce water to the enclosures which results in much more uniform and controllable flow profiles of the water through the device. The entire device may be situated entirely beneath the surface of a pool, pond or fountain, with a clear glass or plastic tube extending above the water level to provide a visibly nonintrusive protective path for the laminar output flow.
    • 本发明提供一种用于生产基本上无湍流的流体层流输出的方法。 本发明利用一种输入罐或外壳,其包括减少湍流和流动矫正装置,用于产生湍流的自由输出水流。 该外壳使用切向输入端口将水引入外壳,这导致水通过设备的更均匀和可控的流量分布。 整个设备可以完全位于游泳池,池塘或喷泉的表面下方,其中透明的玻璃或塑料管延伸到水面之上,为层流输出流提供明显的非侵入性保护路径。

    • An ice display device includes a chill tube and a piston that slides within the chill tube providing a fluidtight seal against the interior. The tube is filled with water and cooled to form an ice column. A shutter may selectively close the upper end of the chill tube with a fluidtight seal while the ice column is formed. The tube is warmed and the piston is lifted to an upper end of the tube to display the ice column. A plurality of water nozzles may selectively discharge streams of high pressure water inwardly to sculpt the ice column. An armature may extend upwardly from the piston to support and cool an interior of the ice column. The tube and armature may be cooled and warmed by a thermal transfer fluid. A device may be provided to induce turbulence in the thermal transfer fluid.
    • 冰显示装置包括冷却管和在冷却管内滑动的活塞,其提供抵靠内部的流体密封。 将管填充水并冷却以形成冰柱。 当形成冰柱时,挡板可以选择性地关闭冷却管的上端,并具有流体密封。 管被加热并且活塞被提升到管的上端以显示冰柱。 多个水喷嘴可以选择性地向内排出高压水流,以对冰柱进行雕刻。 衔铁可以从活塞向上延伸以支撑和冷却冰柱的内部。 管和电枢可以被热传递流体冷却和加热。 可以提供一种装置来引起热传递流体中的湍流。
