Title: Method of separating uranium
IPC: G21C19/46
Filed: 1947-02-19
Abstract: Uranium is separated from plutonium and fission product elements in aqueous acid solution by neutralizing the aqueous solution, adding a salting-out agent before or after neutralization, and extracting the uranium by treatment with a water-immiscible organic solvent. Preferably the aqueous solution is formed by dissolving neutron-irradiated uranium in nitric acid, although perchloric acid may be used.  The salting-out agent may be a water-soluble nitrate, e.g. ammonium, sodium, or magnesium nitrate.  Suitable solvents are ethers, ketones, esters, ester ethers, alcohols and aldehydes, examples being diethyl ether, mesityl oxide, methyl isobutyl ketone, diethyl carbitol, ethylene glycol monobenzyl ether, carbitol acetate, beta ethoxyethyl acetate, ethyl citrate, ethyl acetate, n-butyl alcohol and n-amyl alcohol.  In an example, pile-irradiated uranium sheathed in aluminium is treated with sodium hydroxide to remove the aluminium and dissolved in nitric acid; the solution is neutralized with ammonium hydroxide, ammonium nitrate is added, and uranyl nitrate is extracted by three treatments with ethyl ether, plutonium and fission products remaining in the aqueous phase.

Abstract: 673,952. Clocks. MAAR, Z. Feb. 23, 1949 [March 15, 1948], No. 4932/49. Class 139 A device for winding clocks mounted on vehicles is characterized in that it is secured to the steering wheel of the vehicle and is enclosed in a casing which accommodates the mainspring of the clock and at least two oscillating bodies which oscillate during movement of the vehicle and, through gearing wind up the mainspring. The weight 4, Figs. 1 and 3, is oscillatable about an axis 2 and is mounted by means of ball bearings 7 and 9 on coaxial spindles 6 and 10. The spindle 6 is fixed to the casing 1 and the shaft 10 is rotatably mounted by means of ball bearings 11 and 12 in a sleeve 13. A shaft 3 carried by opposite ball bearings 16 in journals 17 mounted in eyelets of the weight 4 carries two weights 5. Fixed to the inner end of the shaft 10 is a level wheel 21 which engages two bevel wheels 20 mounted by ball bearings 19 on the shaft 3. The weights 5 carry pawls 23 which engage ratchet wheels 22 respectively fixed to bevel wheels 20. The casing 1 is fixed to the steering wheel so that vibrations of the vehicle and movement of the steering wheel will result in oscillations of the weights 4 and 5. The oscillations of the weights 5 are transmitted to the shaft 10 by pawls 23 via ratchets 22, bevel wheels 20 and bevel wheel 21. The oscillations of the weight 4 are transmitted to the shaft 10 via bevel wheels 20 and bevel wheel 21. The shaft 10 is prevented from reverse rotation by a pawl and ratchet mechanism and carries a pinion 24 which drives the winding train of the mainspring.

The method of assembly of a discharge device comprises the step of unbondedly mounting cylindrical electrode elements 42, 44, 46 on to a jig 121, and fitting over these elements flanged support members 54, 56, 58; inserting i n t o t h e cylinder 42 a heating element 111, and inserting through apertures in a ceramic disc 14 mounted on flange 125 of jig wall 122 a number of conducting support wires 22, 24, 26, 28; each of which extends either to one of the flanged support members 54, 56, 58; or act as leads for the heater coil 111. Each flange is further held in place by two molybdenum wires which do not extend through the disc but are supported in it, and small copper balls are inserted in the unfilled parts of the apertures in the ceramic disc. Each of the lead wires is in contact with a coating 98, 86, 88, 94 of a material such as copper placed on the insides of the ceramic apertures. The various sets of support rods and wires -for each member are arranged symmetrically on concentric circles at an angular spacing of 120 degrees relative to their centres, and at an angular spacing of 60 degrees from the rods in adjacent circles. The ends of the support rods in contact with the flanged support members have a small quantity of copper disposed between them and the surface of the annular slots inthe flanges which they engage. The whole structure is then baked and the various copper coatings, layers, and balls are melted and on cooling the assembly forms a unitary structure; the temperature of the processing being such that the molybdenum layer 16 on the ceramic disc does not melt. The structure is removed from the jig and an emissive member is inserted over the cylinder 42 around the end of the heater, and the structure is placed in a metal envelope, the assembly is then heated to about 800‹C. in a continuously evacuated chamber and out-gassed. Several minutes later when the out-gassing is completed the temperature is raised to 950‹C. and sintering and brazing of the members into a complete assembly is completed.
