IPC: G21C3/34
Filed: 1969-06-18
Abstract: 1,204,657. Fuel elements. COMMISSARIAT A L'ENERGIE ATOMIQUE. 18 June, 1969 [2 July, 1968], No. 30797/69. Heading G6C. A spacer grid for a fuel element assembly comprises a lattice of interassembled sheet metal members 2, 4 which define compartments having a square section, each member 2, 4 being cut-out and comprising two parallel rectilinear ribbon elements 2a, 2b, 4a, 4b, narrow corrugated strips 12 forming a number of projections (e.g. 13, 14, 15) on each side of the member and defining openings 10 between the ribbon elements, and slits 18, 20 forming interruptions in one of the ribbon elements 2a, 4b in the centreline of each opening 10 so as to permit the insertion of the continuous ribbon element 2b, 4a of another sheet metal member. The sheet metal members 2, 4 are attached at their extremities to similar sheet metal members (Fig. 1, not shown) which form the sides of an outer frame. Each ribbon element 2a, 2b, 4a, 4b is provided, in line with the corrugated strips 12, with bosses 16 directed towards the same side as the projections 13, 15 but of greater height. Each compartment of the grid is limited on each of its four sides by a portion of a sheet metal member, the central part of which is formed by a corrugated strip 12, whilst the corners of each compartment are cut away since they are formed by the junction of the ribbon elements adjacent openings 10. Each fuel element will be in contact on the one hand with the projection 14 of a sheet metal member 2 and the bosses 16 of the adjacent member 2 and on the other hand with the projection 14 of a sheet metal member 4 and the bosses 16 of the adjacent member 4. The flexibility imparted to each corrugated strip 12 by the projections 13, 15 serves to absorb deformations while permitting the coolant to flow between the strip 12 and the fuel element. For the purpose of guiding control rods, guide tubes can be placed in some of the compartments and secured to the corners of these by means of radial fins. In a fuel element assembly, a number of the abovedescribed grids are secured to each other and to the top and bottom support plates of the assembly by means of spacer tubes, which serve also as passageways for the guide tubes.

Filed: 1966-07-12
Abstract: 1,122,258. Hump yard control system. SIEMENS A.G. 12 July, 1966 [12 July, 1965], No. 31348/66. Heading B7N. Retarder release delay, resulting in a lower leaving speed than that required, is overcome by signalling release of the retarder at a higher speed equal to the desired release speed plus a value # V equal to K.a.t/m where K is the mean retarder braking force, a is the number of axles in the retarder, t is the retarder release delay and m is the weight of the cut. Each axle weight signal is fed in digital form from weighing device 2 to a store 7 and also triggers a monostable circuit 8 to its "on" condition. When the circuit drops back to its initial state interrogator 10 is triggered and reads the stored weight into a further store 11 which totals all the axle weights of the cut. This is transformed to analogue form by digital/ analogue converter 13 and applied as one input to divisor circuit 21. Signals representing the number of axles entering the retarder, detected by axle counter 3, are applied to the counting-in input 15 of counter 16 and similar signals representing axles leaving the retarder are applied to the counting- out input 17; the count in the counter, representing axles in the retarder, is applied to digital/analogue converter 19 and thence to a second input to the divisor circuit. The circuit, which is also supplied with constant signals representing the retarder braking force and the delay time, supplies an output representing #V which is added to a signal representing the required leaving speed in adder 23 and the resultant speed signal is applied with a signal representing the actual speed of the cut, obtained from radar speed measuring device 6, to a comparator 26 which supplies a release signal to the retarder when the speed values are equal.

Abstract: 520,765. Chain conveyers for newspapers &c. IGRANIC ELECTRIC CO., Ltd., RAPLEY, H. H., and RAWLINS, G. H. Oct. 31, 1938, No. 31507. [Class 78 (i)] Newspapers or like articles n delivered in overlapping relation in succession from a conveyer A are separated in bundles between the prongs 1 of a chain conveyer B. Each prong is tilted rearwardly on approaching the loading point and then makes a sharp short forward movement beyond the vertical position to separate the bundle from the succeeding papers, before settling down to a vertical position on the main run, finally being tilted forward at the delivery point. Each prong is pivoted at 3 and is under control of a spring 4 which tilts it to a position inclined forwardly when free to act. An arm 5 carried by the prong is depressed by the cam bar 6 on approaching the loading point to incline the prong rearwardly. On entering the recess 7 in the cam the arm 5 is released and the spring tips the prong forwardly. The continuation of the cam bar restores the prong to the vertical position. At the discharge point, the arm 5 leaves the cam-bar and the spring then tilts the prong forward to the limit allowed by the adjustable stop 11. Every alternate prong may be pivoted at 13 in its carrying frame so that it can be turned down by hand into the dotted line position, thus leaving the remaining prongs to handle bundles of twice the number of papers. Specification 508,227 is referred to.
