Abstract: 268,716. Krupp Akt.-Ges., F. April 3, 1926. [Convention date]. Grant of Patent refused. Purifying.-Iron and steel are deoxidized to an oxygen content of less than 0.005 per cent which is determined as part of the manufacture by the fact that the aged state does not cause any substantial decrease in the tenacity of the notched bar under test. In making this iron or steel, a quantity of molten metal is heated in a smelting-oven, and a quantity of aluminium or other agents, e.g. titanium, zirconium, vanadium, magnesium, or silicon, is introduced. The metal is de-oxidized and run off. After solidification, a trial rod is cut off, and is submitted to artificial decay A sample is cut off from this. and is submitted to a cutting-test. The quantity of aluminium &c. is varied until the result of the test is satisfactory. The process may be carried out by means of carbon in a vacuum.

Title: Improvements in or relating to the production of aminoaryl sulphone amidoximes
Filed: 1943-10-07
Abstract: Amidoximes of the general formula <FORM:0583592/IV/1> are prepared by the action of hydroxylamine or an N-substituted hydroxylamine on an aryl sulphone nitrile of formula <FORM:0583592/IV/2> where X is an amino group, a substituted amino group or an acylamino group, and R1, R2, R3 and R1 are hydrogen, or alkyl, aryl or aralkyl groups. Starting materials mentioned include p-aminobenzene sulphonyl acetonitrile, a -(p-aminobenzenesulphonyl) propio- and butyronitrile, p-aminobenzene sulphonyl phenylacetonitrile, and a -(p-aminobenzene sulphonyl) b -phenylpropionitrile. Hydroxyl-amines mentioned include N-alkyl, N-aryl, and N-aralkylhydroxylamine.  The reaction is carried out by merely shaking the reactants together.  If desired the hydroxylamine or substituted hydroxylamine may be liberated from a salt thereof in situ.  Suitable media in which the reaction may be carried out comprise the lower alkanols such as ethanol and isopropanol, used either as such or in admixture with water.  In an example, sulphanilyl acetonitrile hydrochloride is treated with hydroxylamine hydrochloride in aqueous alcohol solution in the presence of sodium carbonate to give sulphanikyl acetamidoxime.

Title: Improvements in or relating to nuclear reactors
IPC: G21C1/24

Abstract: 789,117. Nuclear reactors. STICHTING REACTOR CENTRUM NEDERLAND. July 16, 1956 [July 18, 1955], No. 21930/56. Class 39(4). In a reactor having fissile material in suspension or solution in ordinary or heavy water, the water is evaporated in a reaction zone 3. The walls of this zone, the reflector surrounding it, and any solid structure within the reaction zone, are constructed of graphite. Graphite is preferred to zirconium, which is expensive, and to aluminium, which has to be coated to prevent corrosion, the coating increasing absorption of neutrons. A pressure shell 1 surrounds the reactor and is lined at 11 with an insulator to prevent electrolytic corrosion. Steam from the reaction zone 3 passes through a separating zone 4 and a bed of Berl saddles 10 to remove fissile suspension, and a channel 6 to produce mechanical energy or for heating. Water is returned to the reactor through pipes 7 and finds its way back to a mixing zone 2 through reflector blocks of graphite 5, where its presence augments the moderating effect of the graphite and through the separating zone 4 where it washes down any fissile material deposited on horizontal surfaces. The fissile material is uranium which may be enriched with U<SP>235</SP> or U<SP>233</SP> or Pu<SP>239</SP> and may include Th<SP>232</SP>. Specification 789,937 is referred to.

Title: Process for the complete or substantial removal of free acid from mixtures containing free acid and acid alkyl esters
IPC: C07C51/42
Filed: 1947-08-12
Abstract: Free acid is substantially or completely removed from mixtures containing strong inorganic oxygen-containing polybasic acids and acid alkyl esters thereof by a process wherein a portion of the free acid is first separated as a separate layer from the mixture by setting or centrifuging without the addition of water and thereafter the mixture which has thus been partially freed from acid is treated with a small amount of water or aqueous medium, e.g. an aqueous solution of a salt, base or acid for the purpose of promoting further separation of the mixture into an acid layer and an acid alkyl ester layer.  Mixtures obtained by treating aliphatic primary or secondary alcohols or alkenes, especially alkenes or alcohols having more than 5 carbon atoms, with sulphuric acid or phosphoric acid are suitable for the above treatment.  In an example, a vapour phase crack distillate of boiling range 160-300 DEG  C. from paraffinic material is fed into the bottom of a tower dome which 90 per cent sulphuric is fed; the sulphation product is removed at the top of the tower and is passed to a centrifuge from 84 per cent sulphuric acid runs off; the sulphation product is then mixed with 3 per cent of water and passed to another centrifuge from which 65 per cent acid runs off. The purified acid alkyl esters are worked up to the sodium salts, the yield being 80 per cent.  The 84 per cent acid can be mixed with 96 per cent acid to provide sufficient 90 per cent acid for re-use.  In an experiment illustrating the known method, the sulphation product from the tower is mixed with 15 per cent of water and centrifuged. Substantially acid-free esters, in only 65 per cent yield due to hydrolysis, and 65 per cent sulphuric acid are thus recovered; on mixing the 65 per cent acid with 96 per cent acid to obtain 90 per cent acid for re-use it is found that more acid is formed than is required for the next sulphation cycle, thus necessitating concentration apparatus.  Specification 459,080 is referred to.
