Title: Method of and apparatus for cold drawing metal tubes
IPC: B21C37/30
Filed: 1962-12-03
Abstract: 955,245. Drawing tubes. BABCOCK & WILCOX CO. Dec. 3, 1962 [Dec. 4, 1961], No. 45497/62. Heading B3P Apparatus for processing eccentric metal tubes comprises a draw-bench having means for selectively tilting the die from a plane normal to the axis of the tube, and a mandrel. The die 10 has a frusto-conical entrance portion 11 merging into a frusto-conical exit portion 12 and is mounted for tilting movement in a holder, the angle of tilt being co-ordinated with the amount of eccentricity in the tube 13. As shown in Fig. 2, the die is tilted about a transverse horizontal axis, such a position is used to correct tube eccentricity when the minimum wall thickness lies at the top of the tube. As the zone of minimum wall thickness changes its location angularly of the tube, the direction of the tilt of the die will be manually or automatically rotated a corresponding amount. The action of the die produces circumferential flow of the metal and thickens the thin wall portion of the tube. The diameter of the mandrel may be selected to effect uniform thinning of the tube wall, after the correction of the eccentricity.

Filed: 1963-12-12
Abstract: 1,122,841. Reactors. UNITED POWER CO. Ltd. 12 March, 1965 [12 Dec., 1963], No. 49179/63. Heading G6C. A liquid-cooled nuclear reactor, e.g. a sodiumcooled fast reactor, in which cooling of the reactor contents is possible after the main heat exchangers have been rendered inoperative by the transmission of shock waves through the liquid coolant from a reactor core nuclear explosion has a gas-filled shock wave attenuating space between the reactor vessel 4 and an outer containment chamber 14, an emergency heat exchanger and circulatory pump unit 7 communicating with this space to receive coolant liquid released from the reactor vessel 4 if this should fracture. The bottom 4a of the reactor vessel 4 is thinner than its side walls and is therefore more readily frangible. The reactor core 1 is housed within the reactor vessel 4 beneath the normal surface level 3 of the coolant, the main heat exchanger and circulatory pump units 6 communicating with the reactor vessel 4 by means of ducts 5 which enter the vessel below the coolant level 3. In the event of a core explosion, the sides of the reactor vessel 4 will deform plastically outwards, but are of sufficient thickness as not to rupture or strike the wall of the chamber 14. The bottom 4a will, however, fracture and release the coolant from the core 1 and the reactor vessel 4. The dimensions of the chamber 14 are such that the coolant level does not fall below the core 1. The provision of the space between the reactor vessel 4 and the chamber 14 and of a suitably thick reactor vessel wall restrict damage to the chamber 14, and damage to the emergency heat exchanger 7 will be obviated. Coolant from the fractured reactor vessel is pumped via tubes 12, 13, annular headers 10, 11 and tubes 8, 9 through the emergency heat exchanger 7 and back into the reactor vessel 4. To safeguard against the possibility that an explosion sufficient to damage the main heat exchangers might not fracture the reactor vessel, a remotely-operated broaching tool may be included to perform this task and release the coolant into the bottom of the containment chamber.
