Title: Motion restraining apparatus for a nuclear reactor
IPC: G21C5/00
Filed: 1977-06-29
Abstract: A typical embodiment of the invention provides a means for restraining the fuel elements within a nuclear reactor core from movement during reactor operation. Illustratively, within one of the fuel element end fittings a rectangular grid of torsion bars is positioned with the ends of each of the bars anchored in opposing parallel sides of the end fitting. Individual torsion arms fastened to the midportion of each of the respective torsion bars protrude above the end fitting to bear against the adjacent grid pads and thereby restrain motion in the direction of coolant flow. In the opposite fuel element end fitting a tube that extends through the length of the fuel element is connected to the center of a convex spring. The two ends of the spring are hinged to respective locking bars that are cammed to move in a direction that is transverse to the axis of the tube. As the fuel element moves in the direction of coolant flow, the tube presses the convex spring flat. The flattening spring, in turn, drives the locking bars into engagement with mating latches on the adjacent support grid to prevent further movement of the fuel element.

Title: Self-adjusting husker
IPC: B02B3/04
Filed: 1978-02-07
Abstract: A grain husker has two decorticating rollers which are accommodated in a housing, one of the rollers being rotatable about a stationary axis, while the other roller is mounted on a carrier which, in turn, is mounted on the housing for pivoting relative thereto in such a manner that the movable roller moves with the carrier closer and farther away from the stationary axis of the first-mentioned roller. A drive for the rollers includes a motor, a driving pulley mounted on the output shaft of the motor, and idler pulley and a driven pulley of the movable roller, all of these components being also mounted on the carrier for displacement therewith, the drive further including a driven pulley of the stationarily mounted roller and an endless element which is trained about all of the above-mentioned pulleys. The driving and idler pulleys, as well as the driven pulley of the movable roller are located in the corners of an imaginary triangle, while the driven pulley of the stationarily mounted roller is located within the imaginary triangle so that the required length of the endless element will always be the same irrespective of the amount of displacement of the movable roller with the carrier within the working range thereof. Thus, as the decorticating rollers wear off, the movable roller will move closer to the stationary axis due to the weight of the components mounted on the carrier or acting thereon, and there is no need for retensioning the endless element during the movement of the movable roller within its working range.

Conductor rings and ring extensions protruding therefrom are supported within the casing structure at one axial end thereof by conductor ring clamp systems and ring extension clamp structures respectively. Circumferential positions of the ring extensions correspond to the circumferential positions of the phase terminals. Phase leads which electrically connect the phase terminals and the ring extensions have standard lengths. the number of phase lead standard lengths equal the number of different radial distances the phase terminals are displaced from the stator core's axis. Attaching the conductor ring clamping systems to the arcuate structural segments permits clamping system disposition at the circumferential positions corresponding to the ring extensions' positions. The ring extension clamp structures connect to the conductor ring clamp systems and provide optimum rigidity to the ring extensions. The conductor ring clamp systems each include two blocks which each have indentations in one edge. The indentations on one block are juxtaposable with the indentations on the other block so as to cooperatively provide openings for the reception and retention of the conductor rings. The ring extension clamp structures are similarly configured, but usually have only one indentation in each block for receiving and retaining the ring extension.
