Abstract: 115,935. Adamson, E. June 21, 1917. Cylinder offset machines.-A travelling-cylinder offset machine for producing a series of repeat designs from a master printing-surface or design on a printing or other surface comprises an offset cylinder mounted to reciprocate over a frame or bed having movable supports for the design and for the surface on to which the copies of the design are transferred by the offset cylinder, and screw or like mechanism with totalizing counters for moving one or both of the supports to make the successive impressions accurately in the required positions. As shown, the machine comprises a frame 1 on the upper bars 2 of which the carriage 4 of the offset cylinder 5 is guided by rollers 3 on the carriage. Supports 13, 23 for the master printing-surface 11 and the printing or other surface 12 on which the offset prints are to be transferred are movably mounted on the frame 2, the support 13 sliding transversely on guides 15, and the support 23 longitudinally on similar guides. After each impression, the support 13 may be moved by means of a screw 14 geared to a shaft 17 operable by a hand-wheel 18 under the control of a totalizing counter mechanism 19. By this means, successive impressions may be printed in a transverse row on the surface 12, after which the slide 23 may be moved longitudinally and another row or rows printed. The slide 23 is moved by a screw 24 and hand-wheel 25 by aid of a second counter mechanism 26. The carriage 4 is moved and the cylinder 5 at the same time rotated by means of a handle 8 geared by spur gears 9, 10 to the cylinder shaft. On the cylinder shaft are split spur gears 6 engaging. racks 7 on each side frame 2, the split gears serving to take up back-lash. The sliding supports 13, 23 are held in the thrusting engagement with their screws 14, 24 by cords and weights such as 21, 20, 27, so as to prevent back-lash. The supports may have circular or oblique movements instead of the rectangular movements described above.

Title: Fluidised solids process for recovery of uranium from zirconium-type fuel elements
IPC: G21C19/48
Filed: 1960-03-15
Abstract: Uranium and zirconium are separated from spent nuclear fuel elements containing them by inserting the element within a fluidised bed of inert granular solids, introducing anhydrous hydrogen chloride to convert the zirconium to <PICT:0925178/III/1> zirconium tetrachloride and recovering the latter, and thereafter introducing gaseous fluorine which reacts with the uranium and fission products to form a gaseous uranium hexafluoride-containing effluent gas which is fractionated to recover the uranium hexafluoride.  The hydrochlorination of the zirconium may be carried out 350-450 DEG C. whilst the fluorination is suitably effected at 350-475 DEG C.  As shown in Fig. 1 a jacketed reactor 10 is provided with a foraminous support 26 for supporting the zirconium clad uranium rod 22.  The reactor is initially heated to 350-450 DEG C. by introducing liquid sodium into the jacket 16 whilst fluidising with a helium or argon stream; thereafter hydrogen chloride is introduced through line 28 whilst coolant is introduced through the jacket to control the exothermic reaction. Zirconium tetrachloride product is withdrawn via a filter 30 to line 32.  Heated sodium is then passed through jacket 16 to raise the temperature to 400 DEG C. whereupon gaseous fluorine in a concentration of 5-100% of the gaseous phase is introduced through line 34; the uranium hexafluoride, plutonium hexafluoride and other volatile fission product fluorides are withdrawn through a line 36 to a distillation zone where uranium hexafluoride is recovered.
