Title: Process for the reduction of organic compounds
IPC: C07C29/00
Filed: 1930-10-08
Abstract: In the process described in the parent Specifications, in which organic compounds are reduced by means of an alkali metal and a lower alcohol under excess pressure of hydrogen, the excess pressure is now produced by means of an inert gas, particularly nitrogen.  It is preferred to take about 10 per cent excess above the quantity of alkali metal theoretically required.  The alkali metal may be used in a finely divided state, e.g. as a dispersion in xylene.  As starting materials may be used esters of carboxylic acids and also all the types of compounds mentioned in Specification 358,721.  In the example castor oil is reduced by means of sodium and n-butyl alcohol under excess pressure of nitrogen.  The product is mainly octadecylene glycol. Specification 351,359 also is referred to.

Title: Improvements in or relating to the manufacture of sintered metallic bodies
Inventor: GRIMWADE MARK FREDERICK
IPC: C22C1/10
Filed: 1960-09-01
Abstract: A sintered body consisting mainly of one or more of the metals Ni, Co and Fe and containing a dispersed refractory oxide such as Al2O3, MgO, B6O, Cr2O3, is formed from a powdered mixture of the metal and/or metal oxide and/or metal compound decomposable by heat to the oxide, and a minor proportion, e.g. up to 3%, of the refractory oxide which is heated to at least 900 DEG  C. in an inert or oxidizing atmosphere to form mixed oxides which are then heated in a reducing atmosphere prior to compacting and sintering.  In the preferred method the metal powder or metal oxide is mixed with an aqueous solution of a water soluble salt which decomposes to the refractory oxide by heating, e.g. the nitrate, acetate, citrate or formate of aluminium, the slurry formed is dried, heated at 900-1400 DEG  C. in an oxidizing atmosphere and the mixture of oxides is then crushed to minus 200 mesh.  The powdered oxides are heated in hydrogen at 300-500 DEG  C. to form the metal/refractory oxide mixture which is then hydrostatically pressed at 25-40 t.s.i. and sintered in H2, N2, argon or vacuum at 1000-1400 DEG  C.  The sintered compact is hot rolled, swaged, cold drawn and annealed to form wire.

Patent GB-773653-A (GB)
Title: Improvements in or relating to process for resolution of dl-alpha-amino dicarboxylicacids
Filed: 1955-10-24
Abstract: Racemic alpha-aminodicarboxylic acids containing 4 or 5 carbon atoms are resolved by dissolving such racemates, together with at least an equivalent weight of L- or D-lysine, in a mixture of water and a C1-C3 alkanol, agitating the solution at a temperature between 20 DEG and 30 DEG  C. for between 10 and 20 hours and separating the precipitated lysine salt from the reaction mixture.  Preferably 1.0 to 1.4 equivalent weights of lysine are employed per equivalent weight of alpha-aminodicarboxylic acid. The solvent preferably contains 7 to 8 parts by weight of water and 1.8 to 2.2 parts by weight of C1-C3 alkanol, such a mixture being suitable for 1 part by weight of alpha-aminodicarboxylic acid.  Specified racemic alpha-aminodicarboxylic acids are DL-glutamic and DL-aspartic acids. Methanol is specified as the alkanol component of the solvent.  The optically active alphaaminodicarboxylic acids may be separated from their lysine salts by dissolving in concentrated hydrochloric acid and crystallizing as the hydrochlorides or by dissolving in water, adjusting the pH to the appropriate isoelectric point and crystallizing as the free acids; the filtrate in each case yields a further quantity of free acid after passage through a cation exchange resin.  The lysine remains adsorbed and may be recovered for re-use by elution with ammonia.  In an example L-lysine is used to resolve DL-glutamic acid and L-glutamic acid and the hydrochloride thereof are recovered from the precipitated L-lysine-L-glutamic acid monohydrate.

Abstract: 446,279. Cupping - press. BERLINERFURTER MASCHINENFABRIK H. PELS & CO. AKT.-GES., 1, Schwerbmerstrasse, Erfurt, Germany. Oct. 23, 1934, No. 30661. Convention date, Oct. 26, 1933. [Class 83 (iv)] The resistance of the draw ring 5 or buffer of a press can be varied in accordance with the kind of work done on the workpiece 6 by altering the pressure required to open the release valve 15 by interposing an adjustable wedge 17 to alter the compression of the spring 19 on the valve. When the die 4 approaches the work 6, the rod 33 on the ram lowers the ejector plate 32 to position 32a and continuing movement cups the work 6 and depresses the piston 13 which thereby forces liquid from the chamber 26 through valves 15 to an overflow chamber 28 where it makes room for itself by depressing the spring pressed piston 29 forming the bottom of the chamber 28. A manometer 34 shows the resistance pressure in the chamber 26. On the return stroke the spring 30 is free to press piston 29 up to deliver back through the valve 16 to the chamber 26 the same quantity of liquid that was forced therefrom during the working stroke. Also after a delay the ejector plate is raised to strike the piston rod 14 and raise the draw ring 5 to strip the work. The position of the wedge in the valve stem 15a is varied as desired by rotating the reversed sleeve 25 thus raising or lowering the ring 23 carrying brackets which adjust wedge 17. The wedge may be replaced by a screw-adjusted cone.
