Abstract: A measuring head is used in measuring an assembly part of a nuclear facility, such as a fuel rod, a fuel assembly box, or a spacer of the fuel assembly. The measuring head is capable of augmenting a comparatively large data base representing the overall aging state of the fuel elements in a simple manner and within a short measuring time. The measuring head has a probe tip on the sensor housing and a layer thickness measuring probe is integrated into said probe housing, said measuring probe working according to the eddy current principle. The contour or the diameter of the fuel rod can be determined by the measured deflection of the probe.

Abstract: The invention relates to an optical sorting system for a color sorting machine. Product is irradiated with visible, infra-red or ultra-violet light by a transmitter. If there is no product in the ray path of the transmission source, all of the light falls onto a residual light receiver. If product is present, on the other hand, the light is partly or wholly scattered back to one or more product signal receivers.

Abstract: An arrangement for the manufacture of solid forging blocks with manipulator pins in which an electro-slag remelt process is used for filling an ingot having a vertical bore hole. At least one consumable electrode is used, and the ingot with the vertical bore is placed on a block table having at least one power connection in the region of the block table and flush with a depression for slag start material. The filling of the core zone is started with this depression having a depth of substantially at least 25% of the diameter of the block bore. A movable starting disk is applied as a lower boundary of the depression, and the slag start material is placed on top of the disk. After formation of liquid slag, the depression is exclusively filled from material of the consumable electrode. The power connection to the starting disk is fed along during the entire remelt process.
