    • A valve assembly is provided for controlling the flow of liquid accumulated in a closed vessel through a drain port in the bottom wall of the vessel. The assembly includes a body member having a first section disposed within the drain port. The body member has a second section extending outwardly from the first section. The first and second sections are provided with a first passage for air venting the vessel interior, a second passage for controlled draining of the accumulated liquid from the vessel interior, and a common opening, the latter having an exposed end. Adjustably mounted on the body member is a valve member having a first segment adjustably disposed with respect to the opening of the body member and a second segment projecting outwardly from the first segment and subtending the body member second section. The valve member second segment is provided with first and second passages corresponding with the first and second passages of the body member. Seal elements are provided on the body member second section and in encompassing relation with ends of the first and second passages formed in the body member. When the valve member is in one position of adjustment, the corresponding first and second passages communicate with one another thereby effecting drainage of the accumulated liquid. When in a second position of adjustment, at least the corresponding first passages are not in communication whereby no drainage occurs.
    • 提供一种阀组件,用于通过容器底壁中的排放口来控制积聚在密闭容器中的液体的流动。 组件包括主体构件,其具有设置在排水口内的第一部分。 主体构件具有从第一部分向外延伸的第二部分。 第一和第二部分设置有用于使容器内部排气的第一通道,用于从容器内部控制排出积聚的液体的第二通道,以及具有暴露端的公共开口。 可调节地安装在主体构件上的阀构件是具有相对于主体构件的开口可调节地设置的第一段和从第一段向外突出并对向主体构件第二段的第二段的阀构件。 阀构件第二段具有对应于主体构件的第一和第二通道的第一和第二通道。 密封元件设置在主体构件第二部分上,并且与形成在主体构件中的第一和第二通道的端部包围。 当阀构件处于一个调整位置时,相应的第一和第二通道彼此连通,从而实现累积液体的排水。 当处于第二调整位置时,至少相应的第一通道不连通,从而不发生排水。

    • A split multipiece flanged journal bearing for use as an engine crankshaft thrust-journal bearing or the like wherein the thrust flanges and journal bearing shells are semi-cylindrical and have interlocking means to prevent rotational motion of the thrust flange relative to the respective bearing shell and with potential replacement interchangeability so that any worn or damaged parts may be replaced without changing the whole bearing and so that any one or all thrust flanges may be replaced without removing the crankshaft from the engine and wherein the notch and interlocking lug at one end of a particular combination of thrust flange and bearing shell is of greater arc length than those at the other end to provide a fail-safe feature to assure correct assembly.
    • 用作发动机曲轴推力轴颈轴承等的分体式多重凸缘轴颈轴承,其中推力凸缘和轴颈轴承壳是半圆柱形的,并具有互锁装置,以防止推力凸缘相对于相应轴承壳的旋转运动, 具有潜在的替换互换性,使得任何磨损或损坏的部件可以在不改变整个轴承的情况下被更换,并且可以更换任何一个或所有推力凸缘而不从发动机上移除曲轴,并且其中,一端的凹口和互锁凸耳 推力法兰和轴承壳体的特殊组合的电弧长度大于另一端的电弧长度,以提供故障安全功能,以确保正确的组装。

    • A computer implemented method, apparatus, and computer program product code for temporal, event-based video fingerprinting. In one embodiment, events in video content are detected. The video content comprises a plurality of video frames. An event represents discrete points of interest in the video content. A set of temporal, event-based segments are generated using the events. Each temporal, event-based segment is a segment of the video content covering a set of events. A time series signal is derived from each temporal, event-based segment using temporal tracking of content-based features of a set of frames associated with the each temporal, event-based segment. A temporal segment based fingerprint is extracted based on the time series signal for the each temporal, event-based segment to form a set of temporal segment based fingerprints associated with the video content.
    • 用于时间,基于事件的视频指纹识别的计算机实现的方法,装置和计算机程序产品代码。 在一个实施例中,检测视频内容中的事件。 视频内容包括多个视频帧。 事件表示视频内容中的离散点。 使用事件生成一组基于事件的时间段。 每个时间的基于事件的片段是覆盖一组事件的视频内容的片段。 使用对与每个基于事件的片段相关联的一组帧的基于内容的特征的时间跟踪从每个基于时间的基于事件的片段导出时间序列信号。 基于每个基于时间的事件的片段的时间序列信号提取基于时间片段的指纹,以形成与视频内容相关联的一组基于时间片段的指纹。
