Title: Improvements in or relating to clad steel plates
IPC: B23K20/227
Filed: 1955-06-22
Abstract: 772,859. Making compound sheets; rolling; working at specified temperatures. LUKENS STEEL CO. June 22, 1955 [April 27, 1955], No. 18054/55. Classes 83 (2) and 83 (4). In a method of cladding steel with zirconium a sheet of zirconium 11, Fig. 1, is electroplated on one face with nickel or iron and formed with a steel plate 5 into a hermetically sealed pack which is heated and supplied with inert gas prior to reducing the thickness by rolling to form a bond. The pack is formed between the plate 5 to be bonded and a second plate 6 which is covered with a parting compound 10 such as graphite and has spacer bars 7, 8, welded along its edges to form a recess for the zirconium plate 11 and to which the plate 5 is subsequently welded to form the sealed pack. Argon gas is supplied to the pack through pipes 13 during the welding process and subsequent heating to 1000‹ to 1550‹ F. The heating is carried out for about one hour per inch of thickness after which the pack is rolled, pressed or forged to bring about a reduction of not less than 20 per cent. In a modification two sheets of zirconium are placed back-to-back in a pack formed between two steel-backing-plates.

Patent GB-987651-A (GB)
Title: A process for the removal of impurities from actinides
IPC: B01J20/10
Filed: 1963-05-08
Abstract: In removing impurities from acid solutions containing actinides, e.g. U and Th, a complexing agent is added which forms a water soluble complex with the impurities and the difference in molecular size of the ions so produced is utilized to achieve the separation of the impurities and the actinides.  For example, the impurities are removed by molecular sieves or electrodialysis. The complexing agents used preferably contain polar group, e.g. hydroxy, ether, ester, keto or carboxy groups and are exemplified by ethylene glycol, 1,3-propane diol, 1,4-butane diol, 1,2,6-hexane triol, polyethylene glycols, ketones of the type R1.CO.R2 wherein R1 and R2 are oxygenated hydrocarbon chains, and nitrogenous derivatives, e.g. hydroxylamine, carbamide triethanol amine, and nitrilo tri-acetic acid.  The molecular sieves used are made of acid resistant micro-porous material having a pore size of half the magnitude of the diameter of the complexed actinide molecules but 3-4 times the diameter of the impurity ions, e.g. a siliceous material having a pore diameter between 6 and 12<\>rA.  Compounds of the type UO2(MO3)n.Lm are produced wherein L is the organic ligand, n is an integer either 1 or 2, and m is an integer either 1 or 2.  U.S.A. Specifications 2,717,696 and 2,796,424 are referred to.ALSO:Electrodialysis is used to remove impurities, e.g. fission products, from acid solutions containing actinides, e.g. U, Th and Pu.  A complexing agent is added which forms watersoluble complexes with the actinides but not with the impurities.  The complexed solution is then placed in the anode compartment of a dialysis cell having a microporous diaphragm with a pore diameter of 6-12<\>rA.  The fission products migrate to the cathode because of their positive charge, the complex actinide was being retained by the diaphragm because of their larger molecular size.  A suitable diaphragm is specified as being prepared from sintered titanium or porous polyethylene.  If the complexing of the actinides is carried so far as to produce neutral complexes then a standard diaphragm may be used, or if negative complexes are formed then they are concentrated in the anode space. Suitable complexing agents contain polar groups, e.g. hydroxy, ether, ester, keto, or carboxy groups and many examples are given in the Specification. U.S.A. Specifications 2,717,696 and 2,796,424 are referred to.

Title: Process for the reduction of zirconium and hafnium-tetrachloride with liquid magnesium
IPC: C22B34/14
Filed: 1961-05-18
Abstract: <PICT:0938969/III/1> Zirconium or hafnium tetrachloride is converted to halogenozirconate or halogenohafnate, prior to reduction to metal with magnesium, in the apparatus shown in Fig. 1.  Reactor 1 contains two crucibles 3, 4, located one above the other, their temperatures being independently controlled by heating coils 5, 6. Tetrachloride is placed in crucible 3, and the appropriate salt, e.g. sodium chloride, together with magnesium, in crucible 4. After purging with argon or helium, crucible 4 is heated to a temperature at which the tetrachloride salt system will be liquid, but below the melting point of magnesium, and crucible 3 is then heated to volatilize tetrachloride which diffuses into the salt until saturation is reached.  Heating of crucible 3 is then discontinued, cover 21 closed, and crucible 4 heated to 800 DEG C. to initiate the reduction reaction.

Title: Improvements in apparatus for the transformation of electric alternate currents into direct currents and vice versa
IPC: H02M1/22
Filed: 1928-06-23
Abstract: 292,617. Urbinati, M. June 23, 1927. [Convention date]. Commutator switching-arrangements; polyphase transformers.- In conversion apparatus of the type in which a polyphase transformer is adapted to provide current of a large number of phases associated with stationary segments of a commutator cooperating with synchronously rotating brushes, difficulty arises in obtaining from, for example, a three phase primary, the requisite large number of secondary phases by phase combination due to the value of volts per turn being higher than the amount to be added or subtracted to produce the necessary small phase displacement. This difficulty is overcome by providing in addition to turns on the secondary side embracing the whole of the iron cross-section, turns embracing various fractions of the iron cross-section as shown, so that fractional values of the volts per turn are available for adding or subtracting in combining phases.
