    • Metal oxide-containing dispersions and methods of producing the same are provided. Generally, dispersions according to the invention comprise respective quantities of surfactant, metal oxide, and carrier. Methods according to the invention generally comprise providing a quantity of metal oxide particles of having a desired size suitable for being dispersed in a carrier with the aid of a surfactant. If necessary, the metal oxide particles may be mixed with the carrier and then undergo a pulverization step whereby the average particle size is reduced to the desired level, or the metal oxide particles may be pulverized prior to addition of the carrier. Dispersions made in accordance with the present invention generally exhibit excellent stability in that the metal oxide particles remain suspended in the dispersion for at least about one month.
    • 提供含金属氧化物的分散体及其制备方法。 通常,根据本发明的分散体包含各自量的表面活性剂,金属氧化物和载体。 根据本发明的方法通常包括提供一定量的具有适合于借助于表面活性剂分散在载体中的所需尺寸的金属氧化物颗粒。 如果需要,可以将金属氧化物颗粒与载体混合,然后进行粉碎步骤,由此将平均粒径降低到所需的水平,或者可以在添加载体之前将金属氧化物颗粒粉碎。 根据本发明制备的分散体通常表现出优异的稳定性,因为金属氧化物颗粒保持悬浮在分散体中至少约一个月。

    • A method for determining coverage gaps within a geographical area served by a wireless communication network includes: (a) receiving a location report from each of a plurality of mobile units; (b) storing all location reports received from the mobile units in a database; and (c) searching the database for a position within the geographical area at which an acceptable quality wireless signal has not been received. The location report may include a measured signal quality metric of the wireless link, which may be the signal strength of the wireless link, a bit error rate of the wireless link, or both. Location reports may be displayed on a map to show coverage quality and gaps. Statistical technique and quantitative techniques can be applied on the signal quality metrics reported.
    • 一种用于确定由无线通信网络服务的地理区域内的覆盖差距的方法包括:(a)从多个移动单元中的每一个接收位置报告; (b)将从移动单元接收的所有位置报告存储在数据库中; 和(c)在数据库中搜索未接收到可接受质量的无线信号的地理区域内的位置。 位置报告可以包括无线链路的测量信号质量度量,其可以是无线链路的信号强度,无线链路的误码率或两者。 位置报告可能会显示在地图上,以显示覆盖质量和差距。 统计技术和定量技术可以应用于所报告的信号质量指标。

    • A hydration tank provided with an interior rotating vessel located between a stationary wall of the hydration tank and a stationary wall of a central inlet tube provided centrally within the tank. Liquid flows downward into the tank via a central inlet tube, then upward between the inlet tube and the rotating vessel, and then again downward between the rotating vessel and the tank wall to the exit. Horizontal vanes are provided on both the inside and outside of the rotating vessel that interleaf with horizontally extending stationary vanes provided on the wall of the tank and the central inlet tube. Together, the stationary and rotating vanes constantly mix the liquid in a direction that is normal to the direction of flow of the liquid without interfering with flow of the liquid through the tank.
    • 一个水化罐,设有位于水化罐的固定壁和中央入口管的固定壁之间的内部旋转容器,该中心入口管设置在罐的中央。 液体通过中心入口管向下流入罐中,然后在入口管和旋转容器之间向上流动,然后在旋转容器和罐壁之间向下流到出口。 水平叶片设置在旋转容器的内部和外部,其与设置在罐的壁上的水平延伸的固定叶片和中心入口管相互交错。 一起,固定和旋转叶片一直在与液体流动方向垂直的方向上混合液体,而不会干扰液体通过罐的流动。
