摘要： The socket has an essentially cylindrical outer layer of glass fiber-reinforced plastic and a sealing sleeve arranged in a recess in the outer layer. This sealing sleeve has, between the two socket ends, a rib serving as a stop for the ends of the two pipes to be connected to one another. Here, the outer layer forms a first and a second hollow cylindrical, dimensionally stable edge section, the first of which is substantially longer than the second. That end of such a socket which is formed by the longer edge section can be pushed relatively easily onto a first pipe and can also be nondetachably bonded thereto by means of an adhesive. The second pipe having the same diameter can then be inserted into the socket end formed by the shorter edge section. Here, the relatively short edge section makes it possible to insert the second pipe into the socket with a tight seal even when the axes of socket and pipe do not coincide but make a small angle with one another.
摘要翻译：插座具有基本上圆柱形的玻璃纤维增强塑料外层和布置在外层凹部中的密封套筒。该密封套在两个插座端之间具有用作两个管道的端部彼此连接的止挡件的肋条。这里，外层形成第一和第二中空的圆柱形，尺寸稳定的边缘部分，其中第一部分基本上比第二部分长。由较长边缘部形成的这种插座的这一端可以相对容易地被推到第一管上，并且也可以通过粘合剂不可剥离地结合到其上。然后可以将具有相同直径的第二管插入由较短边缘部形成的插座端。这里，相对较短的边缘部分使得即使当插座和管道的轴线不重合但彼此形成小角度时，也可以将密封的第二管子插入到插座中。

摘要： A fuel element bundle cutter that has horizontal rod bundle feed. A portionf the radioactive dust that is produced when a rod bundle is cut is picked up by scavenging air and is withdrawn with the latter via the chute for the cut-off rod pieces. The bottom of the lower part of the cutter housing, between the housing wall that faces the rod bundle feed and the side walls of the housing, is embodied as a grating, on the bottom side of which is disposed a base plate to which is connected a withdrawal mechanism that includes at least one collecting funnel and withdrawal channel for the remainder of the radioactive dust, which is conveyed by a portion of the scavenging air from the cutter housing. Each withdrawal channel communicates with the chute for the cut-off rod pieces.

摘要： Horizontal fuel element bundle shears have a stepped blade and a horizontalagazine for accommodating an undismantled uclear reactor fuel element which is to be cut up. In the fuel element bundle shears, the nuclear reactor fuel element, for the cutting operation to be performed, is pushed with a stepwise movement through a magazine opening in front of which the stepped blade is displaceable in a direction perpendicular to the longitudinal axis of the fuel element. Each portion of the stepped blade has a cutting edge. In order to achieve a lower rate of wear of the stepped blade while at the same time obtaining a good cut and a low cutting force, the stepped blade has two cutting edges which are separated from each other by a step, thereby forming two blade portions which are in superposed relationship with each other. The lower blade portion is set back with its cutting edge relative to the cutting edge of the upper blade portion by a step distance which corresponds at least to the width of the precompacted fuel element bundle. The upper cutting edge is higher or longer than the lower cutting edge. Because of this configuration, the two blade portions, which are separated by a step, do not come into engagement with the bundle simultaneously but instead engage the bundle sequentially.
摘要翻译：水平燃料元件束剪具有阶梯式叶片和用于容纳要被切割的未拆卸的核反应堆燃料元件的水平仓。在燃料元件捆束剪切机中，用于要进行的切割操作的核反应堆燃料元件被逐步地移动通过料仓开口被推动，其中阶梯式叶片可以在垂直于燃料元件阶梯式刀片的每一部分都具有切削刃。为了实现台阶刀片的较低磨损率，同时获得良好的切削和低切削力，台阶刀片具有两个彼此分离的切削刃，从而形成两个刀片部分它们彼此重叠关系。下叶片部分相对于上叶片部分的切割边缘具有相对于预压缩燃料元件束的宽度的台阶距离的切割边缘。上切割刃高于或低于下切割刃。由于这种构造，通过台阶分开的两个叶片部分不会同时与束接合，而是依次接合束。
