    • Apparatuses for separating solid catalyst particles from a Fluid Catalytic Cracking (FCC) vapor are provided. In one embodiment, an apparatus includes a vessel formed with a vessel wall. A conduit is positioned within the vessel and is configured to direct flow of an FCC vapor-solid stream. The apparatus also includes a channel positioned within the vessel and in fluid communication with the conduit. The channel has a channel inlet with an inlet cross-sectional area and a channel outlet with an outlet cross-sectional area less than about 75% of the inlet cross-sectional area. The channel outlet is configured to direct the vapor-solid stream tangentially toward the vessel wall to separate the solid catalyst particles from the FCC vapor.
    • 提供了用于从流体催化裂化(FCC)蒸气中分离固体催化剂颗粒的装置。 在一个实施例中,装置包括形成有血管壁的容器。 管道定位在容器内并且构造成引导FCC汽 - 固流流的流动。 该装置还包括位于容器内并与导管流体连通的通道。 通道具有入口横截面积的通道入口和出口横截面积小于入口横截面积的约75%的通道出口。 通道出口构造成将蒸汽固体物流朝向容器壁切向,以将固体催化剂颗粒与FCC蒸气分离。

    • Described is a technology by which software program feature usage is located within a sequence of commands collected during program usage sessions. For example, feature generally corresponds to a series of commands, such as copy and paste. A visual modeling component is controlled via drag-and-drop operations to describe a feature model, which is then compiled by a compiler into a finite state machine. Noise models may be used to exclude any command in the sequence that is irrelevant to the feature usage. A recognition process uses the finite state machine to locate program feature usage within the sequence of recorded commands by matching command sub-sequences corresponding to the feature model via the state machine. An analyzer may then use the located matches to provide an analysis report on feature usage.
    • 描述了软件程序特征使用位于在程序使用会话期间收集的一系列命令中的技术。 例如,特征通常对应于一系列命令,例如复制和粘贴。 视觉建模组件通过拖放操作进行控制,以描述特征模型,然后将其由编译器编译成有限状态机。 噪声模型可用于排除序列中与特征使用无关的任何命令。 识别过程使用有限状态机通过状态机匹配与特征模型对应的命令子序列来定位记录命令序列内的节目特征使用。 然后,分析仪可以使用定位的匹配来提供关于特征使用的分析报告。
