Title: Improvements in gas-cooled nuclear reactors
IPC: G21C15/18
Filed: 1962-06-26
Abstract: 1,013,544. Cooling arrangements for gascooled nuclear reactors. BABCOCK & WILCOX Ltd. June 26, 1962 [June 26, 1961], No. 24497/62. Heading G6C. A gas-cooled nuclear reactor having fuel elements disposed in channels in moderating material has solid heat conducting means arranged to transfer heat from the fuel elements to the moderator, which is arranged to be cooled during the operation of the reactor, the thermal conducting properties of the solid heat-conducting means being such that, upon shut-down of the reactor, heat is transferred from the fuel elements to the moderator at a rate approximately equal to the rate of heat generation in the fuel elements as a result of the disintegration of radio-active fission products after the chain reaction has ceased. The principle of the arrangement is illustrated by Fig. 1, where heat generated in nuclear fuel 1 is conducted mainly to the passing coolant indicated by arrows 2 and partly through heatconducting body 3 in the direction of arrows " q " to the moderator 4. The moderator 4 gives off this heat and any other produced in the moderator to coolant stream 5. Coolant streams 2 and 5 may be separate systems or they may be a common circuit as indicated by arrow 6, where the coolant gas first cools the moderator before passing over the fuel element. If the cooling system fails and the reactor is shut down, the heat generated in 1 by radioactive decay is conducted away from the fuel elements by bodies 3 and is stored in the moderator. Figs. 2 to 8 (not shown) illustrate various embodiments of this principle. Figs. 2 and 3 illustrate a liquid moderated reactor with separate moderator and fuel element cooling systems, the fuel element being enclosed in a heat-conducting material which is in close contact with the fuel channel wall. Fig. 4 illustrates a fuel element, having central cooling channels, but which is insulated externally from the coolant stream, thus providing separate channels for cooling the moderator and the fuel elements, the heat conducting means being fins which are insulated from the coolant stream but in contact with the moderator. Figs. 5 and 6 illustrate dished fuel elements with central apertures, the fuel element being equipped with spaced radial flanges which contact the moderator and Figs. 7 and 8 show fuel elements which are frusto-conical shells supported on flanges in grooves in the moderator. In the last two embodiments the construction of the fuel elements provides the passages for coolant flow, and, if desired, the radial surfaces of the fuel elements may be equipped with a helical fin extending coaxially of the central aperture to induce spiral flow of the coolant over the surface. The flanges mentioned above serve as the heat conducting means.

Title: Improvements in process and mechanism for rolling endless lengths of metal in reversible mills
IPC: B21B1/36
Filed: 1937-09-08
Abstract: 485,443. Rolling strip. WILLIAMS, W. P. (American Rolling Mill Co.) Sept. 8, 1937, No. 24502. [Class 83 (iv)] To save wastage of unrolled ends, strip metal is reduced, a length at a time in a reversible rolling mill, the length being virtually segregated, but not severed from the uncoiler 3 and the final coiler 25, for the time being, which, when finished is coiled at 25 and cut off, and then succeeded by the next length to be rolled. The elongation of each length by rolling is taken up by two sets of rollers 13, acting as pulley blocks on which the strip is threaded to and fro, one set being urged away from the other by cable 15 on a drum 16 coupled to a motor 17, whereby tension is maintained on the strip by duplication of this apparatus on each side of the mill. The pull of the drum motor 17 controlled by a rheostat 43 operated by cable 42 from a hydraulic accumulator 41. If the tension tends to vary sporadically, the strip clamps 9 or 22 on each side being pulled a little to one side force liquid from the hydraulic cylinder 40 back to the accumulator 41 so influencing additionally the rheostat 43 of the drum motor 17. An end-to-end welder 4 is provided ahead of the uncoiler 3 for joining short lengths from the uncoiler, the slack required for welding being provided by a slack-forming device 7. A cutter for removing welding flash is also provided at 5. The elongation of each length is shown by a pointer 18 moving over a scale 19 as one set of take-up rollers 13 moves away from its co-operating set. After each length is rolled, the clamps 9 and 22 are opened and a fresh length is pulled through by the coiler 25 in front of which is a shear 24 to sever the coil when big enough which can then be removed and stored away. In another form, Fig. 3 (not shown), the clamps may be dispensed with and the strip tension each side of the rolls is maintained by a jockey roller 34 (not shown) pressed up into a bight of the strip by a hydraulic piston operated from an accumulator, the strip having similar take up devices and being threaded over and under a set of friction rollers 29 (not shown) forming a continuous puller between the take up and the mill.
