Title: Improvements in or relating to the production of uranium and to apparatus therefor
Inventor: LOFTHOUSE ERIC
IPC: C22B60/02
Filed: 1945-03-12
Abstract: Uranium is produced by locally heating to reaction temperature part of a mixture of anhydrous uranium tetrafluoride with an alkaline earth metal (which term includes magnesium) in a reaction vessel, at least that portion of the reaction vessel coming into contact with the reaction mass having a lining of substantial thickness formed of calcium fluoride containing 0.5-2.0 per cent of aluminium sulphate. The vessel may be made of fire-clay or iron and may have a well in the lower part to receive molten uranium produced by the reaction. The lining may be applied as a plastic mixture in which the aluminium sulphate is in an aqueous solution.  Preferably the calcium fluoride should contain at least 15 per cent of particles fine enough to pass a 300 mesh B.S.S. sieve, e.g. 15-30 per cent precipitated calcium fluoride.  The lining is first dried at a temperature of 50-200 DEG C. and then baked at a higher temperature of 400-500 DEG C. Specification 805,191 is referred to.ALSO:A reaction vessel in which uranium is produced by exothermic reaction has a lining coming into contact with the reaction mass of substantial thickness formed of calcium fluoride containing 0,5-2,0 per cent. of aluminium sulphate.

Title: Welding process and apparatus
IPC: B23K9/02
Filed: 1954-03-03
Abstract: 756,201. Welding by fusion. GRAVER TANK & MFG. CO., Inc. March 3, 1954 [May 11, 1953], No. 6252/54. Class 83 (4). In a submerged arc welding process for welding upwardly directed elongated seams, the molten flux and metal is held in place by pressure applied through a strip of compressible heat-resistant material. The strip is of loosely felted glass wool fibres bonded together with a plastic or two such strips may be bonded to the sides of a strip of aluminium foil. A tool for welding a vertical seam consists of a casing 12, Fig. 3, carrying an electrode holder 13, a flux hopper 11 and a roll 19 of the glass wool strip. The tool is pressed against the plates P3 and moved upwardly under the guidance of a projection 23 engaging in the unwelded seam. One end of the strip 20 is secured to the work, and the strip is pressed against the welded seam by a concave roller 22 and a concave wall 25 of the casing 12. A thin layer of the granular flux F tends to be interposed between the layer of molten flux covering the weld and the strip 20 and shields the latter from the heat of the weld. The tool is maintained at the correct distance from the plates by rollers 24 and flanges on the roller 22. The front wall 25 may be inclined towards the plates so as to progressively compress the strip 20. In welding plates of ¢ inch thickness, a weld bead is first deposited on one side of the seam, and then weld beads are simultaneously deposited on both sides to complete the weld. In a modification, Fig. 11, the roller 22 is replaced by a shoe 25C having an upper surface supporting the strip and a concave front face 25E pressing the strip against the welded seam and having edges bearing on the plates P3. The shoe is fixed in the casing 12. In a further modification, Fig. 13, an endless belt 25<SP>1</SP> supports and compresses the strip 20. The belt 25<SP>1</SP> is carried on concave rollers 22, 22A the edges of which roll along the plates P3, and the belt is prevented from slipping by a roller 22B engaging the roller 22A and is tensioned by a spring- loaded roller 22C.

Title: A stereoisomer of cycloheximide and the manufacture thereof
IPC: C07D211/88
Filed: 1957-03-06
Abstract: A composition of matter having the formula: <FORM:0799731/IV (b)/1> and having a specific rotation in methanol solution of between + 12 and + 36 degrees is prepared by isomerizing cycloheximide (actidione) in solution, with or without acid-deactivated alumina for accelerating the isomerization.  The isocycloheximide is found in aged mother liquors from the recrystallization of cycloheximide obtained from fermentation beers, and is separated therefrom by evaporation to dryness, extraction of the residue with a partially chlorinated methane solvent, evaporation of the solvent and recrystallization from a solvent such as amyl acetate, isopropanol, ethyl acetate, n-butanol and mixtures of petroleum ether with chloroform, methylene chloride or diethyl ether, particularly the first two solvents mentioned.  The solutions may be decolorized with active carbon.  The products have melting points at about 100 DEG  C. The isomerization of the cycloheximide may be accelerated by the action of acid-deactivated alumina.  The product has fungicidal activity, but different from that of cycloheximide, and may be used as a mixture of isocycloheximide with cycloheximide, or after separation of the isomers by the usual methods.  The purified isocycloheximide has a specific rotation in methanol of + 36 degrees. Specifications 639,943 and 644,919 are referred to.
