Abstract: Upper and lower core structures of core internals carry a plurality of centering pins which have free ends protruding into recesses in a fuel assembly endpiece. In the case of the upper core structure in particular, the nuts for fixing the centering pins are difficult to access in the event of a subsequent exchange of pins. Therefore, core internals which do not require a nut for securing on the centering pins are preferred. For this purpose, a centering pin is provided with a center bore passing through it. The ends of the center bores facing away from the fuel assemblies are in the form of conically tapering stepped bores. Each stepped bore has a plug which is displaceable in axial direction relative to the centering pin. The peripheral surface of the plug is conically formed in the same direction and with the same pitch as the stepped bore. The centering pin enters into a play-free fitting connection with a bore in a grid plate.

The present invention overcomes these disadvantages by provided a sleeve which engages over the worn ends of the tines and is secured thereto and which has a replacement tine portion secured within the other end of the tubes and extending axially therefrom thus returning the tines to their original length. The sleeves can be secured to the worn ends of the tines either by welding, set screws or other means.

The upper section of the upper plug portion is rigidly attached to the connecting finger on the spider structure, whereas the lower segment of the lower plug portion is rigidly connected to the control rod. Also, the lower section of the upper plug portion and the middle segment of the lower plug portion have complementary threads defined thereon for rigidly threadably attaching the upper and lower plug portions to one another.

Abstract: The closed loop cable system was designed for preventing the theft of coats, but could be used for many other applications. When used for theft prevention, a length of cable is passed through one or both sleeves of the coat to form a loop, and the cable ends, which are provided with mating ferrules are then mated together and then crimped. The cable loop through bath sleeves prevents anyone from trying the coat on, and through one sleeve enables customers to try the coat on, but alerts clerks that it has not been paid for, and thus prevents anyone from putting a coat on and walking out without paying for it. A specialized tool is used to crimp ferrules on the ends of the cable together, and the same tool can be used to cut the cable.

Abstract: Multi-wire steel strand for use under repetitive cyclic load conditions, such as in mechanically pumped wells, is provided with end connecting pieces which are swaged into gripping engagement with the strand in a manner to avoid fatigue failure of the wire at the end connecting pieces, by avoiding abrupt load transitions in the wire. The swaging is such as to gradually and progressively transfer load from the wire strand to the end connecting pieces, preferably by virtue of a gradual and progressive increase of the grip between the wire strand and an end piece, considered in the direction of the terminal end of the strand on which the end piece is mounted, in order to gradually reduce the load in the end portion of the strand and avoid abrupt load transitions therein, which can act as stress risers. A lubricating sleeve insert prevents galling and abrading in the area of relatively slight grip where relative movement may occur, so as to avoid creating stress risers.
