Title: Emergency cooling device for a nuclear reactor
IPC: G21C15/18
Filed: 1975-03-05
Abstract: 1461551 Cooling nuclear reactors ELECTRICITE DE FRANCE (SERVICE NATIONAL) 5 March 1975 [12 March 1974] 9195/75 Heading G6C A reactor, e.g. a sodium-cooled, fast reactor, having a core comprising n independent modules R each receiving coolant flow delivered by respective circulators P, and having associated therewith one or more heat-exchangers E, embodies a cooling arrangement comprising a manifold C from which extend pipes 5 connected to respective pipes K between the outlet of the respective pumps P and modules R. Thus, in the event of failure of a pump, the associated module continues to receive coolant (from the manifold C) to which it is delivered by the pump(s) which continue normal working. Detailed arrangements are described (Figs. 2-4, not shown) for conducting coolant from the manifold to the pipes K.

Title: Thermostats

Filed: 1973-02-26
Abstract: 1402824 Thermostats UNITED KINGDOM ATOMIC ENERGY AUTHORITY 25 Feb 1974 [26 Feb 1973] 9450/73 Heading G1D [Also in Divisions F2 and G3] To regulate the temperature of a fluid, e.g. a coolant such as liquid sodium for a nuclear reactor, flowing through a circuit, a thermostat is provided which consists of a duct 1 having fixed and movable walls 5, 8 defining a path for the fluid between them, the walls 5, 8 having complementary cyclically undulating contours, and means for moving the wall 8 parallel to the wall 5 in response to changes in temperature of the fluid to thereby change the area of the fluid-flow path between the contours. If the temperature falls the flow area is reduced and if the temperature rises the flow area is increased. As shown, the means for moving wall 8, in this case mounted between two fixed walls 5, is a closed reservoir R containing the same fluid as that in the flow circuit. A temperature change causes this fluid to expand or contract and thus contracts or expands bellows 18 thereby moving the wall 8, connected thereto by central spine 16 against the bias of a spring 28. A further fluidfilled closed bellows 29 may be provided to act as an overpressure relief valve. In an alternative embodiment Figs. 7-12 (not shown) only one fixed wall is provided, the reservoir R is defined between two bellows (111), (119) and an argon filled pressure relief capsule (123) is provided.

Patent GB-976337-A (GB)
Title: Improvements in or relating to transfer devices
IPC: B21D43/05
Filed: 1961-03-16
Abstract: 976,337. Moving workpieces. B. J. WALLIS. March 16, 1961 [March 21, 1960], No. 9615/61. Addition to 847,329. Heading B8A. Workpieces 200 are moved horizontally from station to station by two sets of grippers 96. Each set of grippers performs a cycle in the shape of a rectangle and this movement is derived from the vertical movement of ram 12 of a press. The vertical reciprocation of press ram 12 causes horizontal reciprocation of actuator bar 42, by engagement of rack 38, gears 36, and rack 40. The leftward movement of actuator bar 42 causes firstly, the inward movement a (Fig. 1) of grippers 96, and secondly, the leftward movement of carriage 16 which carries grippers 96 to cause grippers 96 to make the longitudinal movement b. Thus the first movement is given to grippers 96 by actuator bar 42 in that rack 50 thereon through the gearing shown rotates shaft 62 which (Fig. 5) carries arms 66 which, through toggle links 68, cause reciprocation of two racks 80; and these racks advance grippers 96 along path a by engagement via gears 82, 84 with rack 90 carried by shafts 92 carrying said grippers. Thus the first part of the movement of actuator bar 42 causes the advancement of grippers 96. At this stage, nut 154 on the bar engages with lock plate 102 and plunger 170 locks the actuator bar to carriage 16. At the same time it disengages lock plate 102 from stop 116 thus releasing the carriage for the latter to be pushed by nut 154 till the carriage is finally stopped by the left-hand stop 116. Grippers 96 have now performed movement b. A change of direction of press ram 12 now changes the direction of movement of acuator bar 42 which proceeds to the right. The first part of the movement of actuator bar 42 now proceeds independently of carriage 16 and via racks 50 and 90 (as before) causes the return movement of grippers 96 along path c. At this stage the left-hand nut 154 engages lefthand lock plate 102. This disengages the lock plate from its stop 116 and cause nut 154 to be looked to carriage 16, the movement of actuator bar 42 causing nut 154 to push carriage 16 to the right to give the grippers 96 their movement along path d. This completes the cycle. Both sets of grippers 96 perform this same cyclic movement so that the workpieces 200 therebetween are progressed leftwards stepby-step.

Abstract: 763,637. Multiple fastenings. RECONSTRUCTION SUPPLIES, Ltd. April 4, 1955 [April 2, 1954], No. 9698/54. Class 44. [Also in Group XVIII] A door for closing autoclaves and the like comprises a plurality of locking bolts c movable radially outward into locking position, an hydraulic ram i<SP>1</SP> for each bolt, and a central chamber l to which high pressure liquid may be admitted to operate the rams to move the bolts outwardly to lock and hold the door in position. Each ram i<SP>1</SP> is secured to or formed with the shank c<SP>1</SP> of its bolt and each is mounted in an hydraulic cylinder i, each cylinder being pivotally mounted upon the door by means of angle brackets h and connected to the central chamber l by a pipe k. In the construction shown, the rams i<SP>1</SP> are double-acting so that the bolts are both shot and withdrawn by hydraulic pressure and each cylinder is therefore connected by a pipe k<SP>1</SP> to a second central chamber l<SP>1</SP>. The central chambers are mounted on the door together with a reservoir n and a pump m. The admission of liquid from the chambers to the cylinders and the exhaustion of the liquid from the cylinders to the reservoir are controlled by a three-way valve o, in the neutral position of which all connections to the cylinders are cut off while in the other two positions the chambers l, l<SP>1</SP> are respectively connected to the hydraulic cylinders to move the bolts to locking position and to withdraw them respectively. The pump is operated by a handle p. The bolts are tapered and engage tapering sockets b in a ring a so that an annular rib f<SP>1</SP> on the door is pressed tightly against packing e in an annular channel to provide a tight seal. The pump m and valve o are carried in a unit r which may be withdrawn as a whole for inspection or repair. In a modification single-acting rams may be used instead of double-acting rams, the return of the rams and bolts being effected by springs.

Title: Triggering device, in particular for land-mines, e.g. anti-tank mines
IPC: F42C7/04
Filed: 1966-03-04
Abstract: 1,117,949. Land mines. INDUSTRIEWERKE KARLSRUHE, A.G. 4 March, 1966 [27 March, 1965], No. 9714/66. Heading F3A. A triggering device for a land mine, e.g. an anti-tank mine, comprises a striker which when the device is rendered operable is held against the action of means which otherwise would cause the movement of the striker required to effect detonation, two tubes filled with a liquid or gaseous medium and each including a pressure responsive member, and a pair of elements associated with the pressure responsive members and serving individually and together to maintain the hold on the striker, each of such elements being actuatable independently by its respective pressure responsive member to release its holding effect on the striker. Each element is arranged to hold in position a retaining ball adapted to hold the striker until actuated by its respective pressure responsive member. When both tubes are simultaneously loaded, both retaining balls are released and the striker detonates the mine. If only one of the tubes is loaded, only one of the retaining balls is released and the other still holds the striker in the safety position. This ensures that the mine only explodes when a tank passes directly over it and not merely to one side. A safety screw-plug fitted in the head of the detonator housing has a transverse slot in which the ends of the elements, e.g. levers, can move when displaced inwards. By rotating the safety screw-plug through 90 degrees this displacement, and hence the triggering of the mine, is prevented. In this latter position of the safety screw-plug, the ends of the elements enter two shallow grooves in the screw-plug perimeter should the tubes be loaded and so prevent the screw-plug from being rotated into a position to release the striker. If the tubes are not loaded, the ends of the elements are free of the two shallow grooves and the screw-plug can be so rotated.
