    • A device for loading catalyst particles into a reaction zone which distributes said particles, at substantially the same rate, uniformly across the catalyst bed area of said zone. The catalyst particle loading device is employed in combination with a catalytic reaction zone. The catalyst particle loading device comprises a hopper having a conical bottom portion provided with an opening at its lower end. The opening is in communication with a catalytic reaction zone. A vertically movable hollow sleeve is coaxially disposed within the hopper. The sleeve has a lower conical end portion which forms with the conical bottom portion of the hopper a throttle valve for the opening. A rotary shaft is coaxially disposed within the sleeve and extends through the opening at the lower end of the hopper and into the upper portion of the reaction zone. A particle-dispersion wheel is attached to the lower end of the shaft below the opening.
    • 用于将催化剂颗粒装载到反应区中的装置,其以基本上相同的速率将所述颗粒均匀地分布在所述区域的催化剂床区域上。 催化剂颗粒装载装置与催化反应区组合使用。 催化剂颗粒装载装置包括具有在其下端设有开口的锥形底部的料斗。 开口与催化反应区连通。 垂直移动的中空套管同轴地设置在料斗内。 套管具有下锥形端部,其与料斗的锥形底部形成用于开口的节流阀。 旋转轴同轴地设置在套筒内并延伸穿过料斗下端的开口并进入反应区的上部。 颗粒分散轮附着在开口下方的轴的下端。

    • A system and method for performing passive coherent location (PCL). A PCL radar system has high speed analog-to-digital converters (ADC) for digitizing RF signals received on antenna elements of an antenna array. The RF signal received by each antenna element is processed by components within a corresponding physical channel. The RF signals are digitized by the high speed ADC and then processed by a frequency channelizer. The frequency channelizer inputs the RF signal into a digital filter bank comprising a plurality of band pass filters. Each filter in the filter bank may have a corresponding filters, which share the same filtering properties, in the frequency channelizers of each of the physical channels. The outputs of such corresponding filters share a frequency channel. Beam forming and PCL processing are performed for each frequency channel on the filter outputs from each physical channel sharing said frequency channel. A target state is estimated.
    • 一种用于执行无源相干位置(PCL)的系统和方法。 PCL雷达系统具有用于数字化在天线阵列的天线元件上接收的RF信号的高速模数转换器(ADC)。 由每个天线元件接收的RF信号由对应的物理信道内的组件处理。 RF信号由高速ADC数字化,然后由频率调节器进行处理。 频率信道器将RF信号输入到包括多个带通滤波器的数字滤波器组中。 滤波器组中的每个滤波器可以具有在每个物理信道的频率通道器中共享相同滤波特性的相应滤波器。 这种相应滤波器的输出共享频道。 对来自共享所述频道的每个物理信道的滤波器输出上的每个频道执行波束形成和PCL处理。 估计目标状态。
