    摘要： A flow sensing apparatus for providing an indication of the presence of an exiting flow stream from a coal processing plant cyclone includes a probe member disposed in the edge of the flow stream, an electronic sensing circuit cooperatively arranged with the probe member in order to provide either a high or a low level signal, depending upon whether the probe member is being contacted by the exiting flow stream or whether such contact is not being made. A display light is cooperatively arranged with the sensing circuit so as to flicker on and off as the exiting flow stream intermittently and irregularly contacts the probe member. The flickering of the display light indicating proper outlet flow from the coal processing plant cyclone while a constantly on condition of the light indicates that flow is not occurring. A time-delay circuit section is included so that if flow is blocked for a predetermined interval of time, an alarm sounds telling the operator that flow has been blocked and that corrective measures should be taken.

    摘要翻译： 用于提供来自煤加工厂旋风分离器的出口流的存在的流量检测装置包括设置在流动流边缘的探针部件，与探针部件配合配置的电子感应电路，以便提供 高电平或低电平信号，这取决于探针部件是否被流出的流动物体接触或者是否没有进行接触。 显示灯与检测电路协同地布置，以便随着离开的流动流间歇地且不规则地接触探针构件而闪烁开启和关闭。 显示灯的闪烁指示来自煤加工厂旋风分离器的适当的出口流，同时灯的持续打开状态表示不发生流动。 包括时间延迟电路部分，使得如果在预定的时间间隔内流动被阻塞，则警报响应于操作者告知流已经被阻塞并且应采取纠正措施。

    摘要： What is provided is an enhanced dynamic address translation facility. In one embodiment, a virtual address to be translated and an initial origin address of a translation table of the hierarchy of translation tables are obtained. Based on the origin address, a segment table entry is obtained which contains a format control field and an access validity field. If the format control and access validity are enabled, the segment table entry further contains an access control and fetch protection fields, and a segment-frame absolute address. Store operations to the block of data are permitted only if the access control field matches a program access key provided by either a Program Status Word or an operand of a program instruction being executed. Fetch operations from the desired block of data are permitted only if the program access key associated with the virtual address is equal to the segment access control field.

    摘要： An electric-cable-grounding piercer has a piercer blade (1) with a trunk end attached to a double-acting hydraulic piston (2) in a double-acting hydraulic cylinder (3) from which a blade housing (4) is extended from a blade end. An insertion-pressure tube (7) is positional in fluid communication intermediate an insertion-pressure end of the double-acting hydraulic cylinder and a pump-outlet conveyance (36) from a hydraulic pump (9). A withdrawal-pressure tube (10) is positional in fluid communication intermediate a withdrawal-pressure end of the double-acting hydraulic cylinder and the outlet conveyance from the hydraulic pump. The hydraulic pump has a control valve (35) for directing pressurized hydraulic fluid to the insertion-pressure end and to the withdrawal-pressure end of the double-acting hydraulic cylinder selectively. The piercer blade has electrical communication with electric cable (6) being pierced for transmission to a ground-line connector (12) to which a ground line (13) is connectable for releasing residual current from the electric cable in preparation for work on the electric cable. An insertion-depth indicator (44) attached to the piercer blade is visible through an indicator slot 45 in the blade housing. A cable attachment, such as a chain clamp (5), is positioned on a cable end of the blade housing for rigid attachment to the cable to be pierced.
