    • A method and computer-readable medium for obtaining information associated with a VoIP communication session includes tapping the computer network passively to obtain signaling and media information in a first format, separating the signaling and media information, determining transport information from at least one of the signaling and media information, transcoding the media information to a second format, and storing the transcoded media information in the second format. The media information includes data, voice, audio, and/or video information. A system obtain information associated with a VoIP communication session on a computer network includes a tapping device to passively tap the computer network to obtain signaling and media information in a first format, a processing device to transcode the media information from the first format to a second format, separate the signaling information from the media information, and determine transport information from at least one of the signaling and media information, and a storage device to store the transcoded media information in the second format.

    • A hydraulic distributor for safely and efficiently top charging a bell-less blast furnace. The hydraulic distributor includes a main housing, an inner ring, a trunnion, and an actuator ring, which act together to lift and rotate the distributor chute. Hydraulic tilt cylinders operatively coupled to the inner ring act to lift the distributor chute to change tilt. Rotational Drives operatively coupled to the trunnion act to rotate the distributor chute. The hydraulic distributor provides improved repeatability and precision control of the distributor chute, and hence the placement of burden materials within the blast furnace resulting in improved productivity and operation of the furnace. The hydraulic distributor provides a less complex design and construction resulting in reduced costs for manufacturing and maintenance.
    • 一种液压分配器,用于安全有效地向无鼓高炉充电。 液压分配器包括主壳体,内圈,耳轴和致动器环,其一起作用以提升和旋转分配器滑槽。 可操作地联接到内环的液压倾斜缸用于提升分配器滑槽以改变倾斜。 可操作地联接到耳轴的旋转驱动器用于旋转分配器滑槽。 液压分配器提供了分配器滑槽的改进的重复性和精确控制,并且因此在高炉内放置负载材料,从而提高了炉的生产率和操作。 液压分配器提供了较不复杂的设计和结构,从而降低了制造和维护成本。
