Title: Nuclear fuel tablets

Filed: 1969-11-06
Abstract: 1281250 Fuel elements SIEMENS AG 6 Nov 1969 [20 Dec 1968] 54520/69 Heading G6C A fuel element comprises a stack of fuel pellets 40 within a tubular casing 8, each pellet 40 having a right cylindrical surface portion joining two end-faces each of which has a depression or dishing 6. Each pellet 40 is bevelled at the periphery of each end-face to form a frusto-conical portion which meets the cylindrical surface portion at the edge in such a manner that the included angle therebetween is in the range from 90À5 degrees to 120 degrees at every point along that edge. There is thus formed at the boundary between each bevelled portion and dishing 6, an annular ridge, the apical line a of which is at such a distance from the lateral surface of the pellet 40 that compressive forces in the fuel element are taken up by a region of the pellet of sufficient strength that spalling of the pellet is avoided. Resultant peripheral gaps b formed between the pellets 40 may be kept small so that no indentation of the casing 8 into these gaps is possible as a result of external coolant pressure. In some cases, however, it may be desirable to produce such indentations by means of somewhat larger gaps in order that the pellets may be more securely held.

Abstract: 1455447 Forging M HILGELAND F ROTH and E SPRINGMANN 29 Nov 1973 [30 Nov 1972] 55326/73 Heading B3H A multi-stage multi-tool press comprises a pair of tool carriers 2, 3 rotatable about parallel axis 7, 9, the outer tool carrier 2 having a set of fixed tools 14 respectively co-operating with the tools 16 mounted on the other tool carrier and slidable in guide pockets 13. The tools 16 are each mounted on a plate 15 which is retained against the tool carrier 3 by flanges 31, 35, Fig. 2, on the carrier but allowed to move relative to the tool carrier in the direction of rotation. Thus as the tool carriers 2, 3 are rotated synchronously the tool pairs 14, 16 are moved together and apart due to a camming action of surfaces 17 on the tool carrier 3 and the offsetting of the axes 7, 9. Each tool 16 comprises a pair of dies 47, 48 which are brought alternately into alignment with the tool 14. A feeding device 20 is associated with each tool 14 and comprises a lever 18, Fig. 10 (not shown), with a slot (55) at its free end to receive a blank. The lever is operated by a cam roller 59 which engages a cam track 63, Fig. 2, on the machine frame. The dies 47, 48 provided on each tool 16 are moved between two limit positions by a toothed member 44, Fig. 3, on the machine frame 1 engaging a toothed wheel 43. Alternatively the movement may be effected by a lever (89), Fig. 15 (not shown), engaging a cam (94) on the frame. The tool 16 is latched in its limit positions. The blanks are sheared from continuous stock by a shear 66 and loaded by the lever 18 into the first die 47 of each die pair. The blank is rough pressed by the tool 14 and die 47 after which the tool 16 is retracted. The tool 16 is displaced to bring the die 48 into alignment with the tool 14 for finish pressing. The two stage operation requires two stations of the tool carriers 2, 3 since the tools 14, 16 are together only once for revolution. The tools 16 are provided with cam operated ejectors and the tools 14 have ejectors 22 operated by a three armed actuator 23, Fig. 1.

Abstract: 1300240 Programmed control E MAYER [trading as MAYER & CIE] 26 Nov 1970 [5 Dec 1969] 56552/70 Heading G3N [Also in Division D1] An electric pattern attachment for a multiplesystem circular knitting machine, having a revolving needle cylinder and electromagnetic needle selectors, comprises a pattern repeat plugboard 400, Fig.1 having a cover plate 402 through which are inserted different length plugs 403-405 having heads 406 indentifiable by shape or colour. The plugs are electrically conductive and engage switching planes A-C whereby a stitch input 1-36 of a row is connectable through diodes 408 to colour signal outputs a-c. The scanning of the plug-board 400 is synchronized with the rotation of a needle cylinder, (not shown), by a mechanically driven co-ordination switchgear 300. The co-ordination switch-gear 300 comprises a stitch wale part 310, having an AND-gate 311 for each stitch row, a system part 320 having an AND-gate 321 for each knitting system, and a cylinder rotation part 330 having an AND- gate 331 for each cylinder rotation required for the run-through of an entire plugged pattern repeat length. The distribution of the pattern colour signals to repeat stores 501, Fig. 2, of an intermediate store, not shown, is effected through a part pattern circuit 420 evaluating the signals a-c to derive 'knit' or 'do-not knit' signals through AND- gates 421, OR-gates 422, NOR-gates 424 and NAND-gate 423. A control circuit 430, determining the system sequence per switch row, has OR- gates 431 which through AND-gates 340 enable AND-gates 350 between the part 330 and the stitch input 1-36. Connecting leads 312, 432 are extended to a scanning device, not shown, for the intermediate store. In a modification, the diodes 408 are built into the plugs 406 and the connectors to the control circuit 430 are reversible by a drum-controller. In an alternative arrangement, for use when the number of stitch wales in the pattern repeat exceeds the number of needles which lie on the needle circumference between consecutive knitting systems, the plug-board is divided into a number of sections with associated co-ordination switchgears arranged to transfer smoothly in synchronism with cylinder rotation.
