摘要： An improved fluid mandrel having an eddy current probe connected thereto is disclosed herein. The eddy current probe generally comprises a probe body which is detachably connectable to the bottom of a fluid mandrel on one end, and a source of hydraulic fluid on the other end. The probe body includes a pair of sensing coils which are separated along the longitudinal axis of the body by a distance approximately equal to the thickness of the metallic structure desired to be detected. The improved mandrel finds particular application in performing expansions which eliminate the clearance between heat exchange tubes extending through the baffle plates in nuclear steam generators. In such an application, the sensing coils of the probe are longitudinally spaced the same distance as the thickness of the baffle plates in order to generate a sharp and unambiguous electronic signal indicative of the relative positions of the mandrel and the baffle plate.
摘要翻译： 本文公开了具有连接到其上的涡流探针的改进的流体心轴。 涡流探针通常包括探针主体，其可拆卸地连接到一端上的流体心轴的底部，另一端上具有液压流体源。 探针主体包括一对感测线圈，它们沿主体的纵向轴线分开大约等于期望被检测的金属结构的厚度的距离。 改进的心轴在执行膨胀时具有特别的应用，其消除了延伸穿过核蒸汽发生器中的挡板的热交换管之间的间隙。 在这种应用中，探头的感测线圈纵向间隔与挡板的厚度相同的距离，以产生指示心轴和挡板的相对位置的清晰且明确的电子信号。

摘要： The device comprises a pair of locating pins extending outwardly of an edge surface portion of one of the cabinets and adapted to be received in complementary through openings in the corresponding edge of the adjacent cabinet to be connected, the outer ends of the locating pins being conically rounded to provide for horizontal and vertical alignment by cam action. An elongated, lever controlled interlock member serves to interclampingly engage turned down skirt portions of the thus aligned cabinet edges to retain the cabinets in interlocked relation.
