Title: Treatment of aqueous fission product solutions
IPC: G21F9/06
Filed: 1948-07-14
Abstract: An aqueous fission product solution containing ammonium nitrate is treated with a carboxylic acid anhydride to react with and destroy the ammonium nitrate, and the solution is then concentrated by evaporation.  Acetic, propionic, and butyric anhydrides are suitable. The aluminium sheath of irradiated uranium rod is removed with caustic solution and the rod dissolved in nitric acid; the solution is saturated with ammonium nitrate and extracted with an organic solvent to remove plutonium.  The aqueous phase may then be neutralized and the uranium extracted with diethyl ether or methyl isobutyl ketone.  The residual ammonium nitrate solution is added slowly to excess acetic anhydride and the mixture refluxed, ammonium nitrate reacting to form acetic acid and nitrous oxide.  The reaction mixture may be distilled to dryness, and any acetamide in the residue destroyed by adding nitric acid; the ammonium nitrate formed is removed by another treatment as specified above.  Alternatively the amide may be destroyed by treatment with nitrogen dioxide.

Filed: 1948-07-16
Abstract: 653,699. Fluid-pressure gauging-apparatus. SHEFFIELD CORPORATION. July 16, 1948, No. 19133. Convention date, Sept. 27, 1947. [Class 106 (ii)] In apparatus of the air-gauge type in which gauging nozzles 21, 22, 23 are obturated by a circular workpiece and a check on the truth of the workpiece is obtained by rotating the workpiece and gauging head relatively to one another between 120 and 180 degrees, an indicator is provided which will complete a circuit to a lamp or other device if the variation in diameter exceeds preset tolerances. Variations in pressure due to different quantities of air escaping from the nozzles 21, 22, 23, are detected by a Bourdon-type pressure gauge 29 connected at 30 to an arm 31 carrying at its upper end ears 34, 33. Each ear is provided with an insulating bush 35, 38, and an adjustable screw 36, 39. Mounted between the insulated contact screws 36, 39 is a slidable plunger 46 to which one connection 45 is taken, the other connection 42 being taken to a lug 41 in contact with the screw 39. The operation of the device is as follows : A workpiece is inserted in the gauging head and rotated approximately a half turn, the maximum pressure induced by this operation, corresponding to the maximum diameter, causing the arm 31 to move to the right, carrying with it screw 36 which in turn moves the sliding plunger 46 a certain distance to the right towards contact screw 39. The workpiece is then rotated again through a half revolution relative to the gauging head ; any reduction in pressure due to smaller diameters at any point on the workpiece, causing the arm 31 to move to the left, carrying the contact screw 39 towards the plunger 46 which remains in the maximum diameter position after screw 36 moves to the left. If the variation in diameter is sufficiently great the contact screw 39 will make contact with the sliding plunger 46 to complete the circuit to an indicator lamp or other device to draw the operator's attention to the fact that the workpiece is over the tolerance set by the positioning of the screws 36, 39. For hollow workpieces a gauging head having nozzles 56, 57, Fig. 5, may be employed.

Title: Improvements in tube testing machines
IPC: G01M3/28
Filed: 1933-07-13
Abstract: 401,621. Testing tubes for leakages. TRAUT, R., 69, Friedrichstrasse, M³lheim Ruhr, Germany. July 13, 1933, No. 19891. Convention date, Oct. 27, 1932. [Class 106 (ii).] In a process for testing the fluid-tightness of steel or cast-iron tubes wherein all the steps are carried out automatically, the apparatus is constructed so that two or more tubes of various lengths may be simultaneously secured in the testing position. The tubes 1 to be tested are fed in pair intermittently by conveyer chains 23 from a surface 41 to the testing position between opposed pairs of nozzles 12, 17. A cam shaft 30 rotated continuously by an electric motor 32 operates an air control valve 35 to actuate a piston 10 and advance by means of pivoted links 8, 7 an abutment 6 carrying the nozzles 12, which thus engage one end of the tubes 1, and force the other end into the nozzles 17. The latter are held in a fixed, adjustable slide 15 by means of rams 16 subjected to air pressure from a cylinder 19 acting on water. A contact disc 37 on the shaft 30 completes the circuit through electromagnets 38 which are advanced together with the abutment 6 and draw the tubes 1 downwards into the jaws of the conveyer chains so that they are not bent during the clamping. The cam shaft 30 now operates a valve 36 to admit water to the tubes 1 by way of a distributing member 14, the pipe 13 and the nozzles 12, the air in the tubes 1 escaping by a valve 18. After the water pressure test has lasted a few seconds, the valve 36 is operated to discharge the water from the pipe 13, and the air valve 35 is operated to withdraw the abutment 6, thus releasing the ends of the tubes 1 from the nozzles 12. Further movement of the abutment 6 causes the electromagnets 38 to be moved by stops 40, and this moves the tubes 1 to release their other ends from the nozzles 17. The contact disc 37 now breaks the electromagnet circuit and the tubes 1 are free to be moved by the conveyer chains to the other side 42 of the machine.
