IPC: C07C/
Filed: 1964-02-11
Abstract: Trimethyl adiponitrile is prepared by a continuous process by feeding trimethyl adipic acid and ammonia into a reaction vessel maintained at 240 DEG  to 290 DEG  C. and having a superposed fractionating column, utilizing residue formed in the reaction vessel to dissolve trimethyl adipic acid and removing the more volatile substances formed during the reaction from the top of the column, removing the crude trimethyl adiponitrile so formed through a lateral outlet of the column, and removing surplus residue formed in the reaction vessel; the reaction being effected in the presence of a catalyst. Ammonia may be separated from the volatile substances removed from the top of the column and recycled to the reaction vessel.  Further, water may be additionally separated from the volatile substances and at least part of the residual volatile substances recycled to the top of the column.  The catalysts employed in the process of the invention are those which may be employed to catalyse the production of adipodinitrile by the liquid phase reaction of ammonia and adipic acid.  The oily mixture obtained by the oxidation of trimethyl-cyclohexanol and/or trimethyl cyclohexanone with nitric acid may be employed in place of pure trimethyladipic acid as reactant.

Title: Manufacture of 4-hydroxycoumarin derivatives
IPC: C07D311/46
Filed: 1952-03-05
Abstract: 3 - (a  - Phenyl - b  - acetylethyl) - 4 - hydroxycoumarin is prepared by condensing 4-hydroxycoumarin with benzalacetone dispersed in water containing ammonia or an organic amine in an amount sufficient to give at least 50 per cent of the theoretical yield. Suitably, the amine is present in an amount of up to 5, 15 or 50 moles. per 100 moles of 4-hydroxycoumarin.  Specified organic amines are pyridine, aniline, triethylamine, tributylamine, triethanolamine, piperidine, diethylamine, diethanolamine and monoethanolamine.  The product obtained using up to 15 mole per cent of catalyst is usually a solid which is isolated by refluxing in a hydrocarbon or chlorinated hydrocarbon solvent, e.g. benzene, cooling, separating the solid material, filtering, dissolving the residue in caustic alkali solution and acidifying to precipitate the pure 4-hydroxycoumarin derivative. The product obtained when more than 15 mole per cent of catalyst is used is usually a semi-plastic residue and it is necessary to extract the cooled benzene solution with dilute hydrochloric or sulphuric acid to cause the product to precipitate.  In examples, 4-hydroxycoumarin is condensed with benzalacetone by heating in an aqueous medium with (1) and (3) triethylamine; (2) ammonia; (4) aniline, and (5) and (6) tributylamine.  U.S.A.

IPC: B27K5/00
Filed: 1949-03-07
Abstract: 664,924. Treating wood with vapours. SOC. ANON. DES ATELIERS DE SECHERON. March 7, 1949 [March 12, 1948], No. 6199/49. Class 140. [Also in Group XIII] Lengths of timber are seasoned by applying a sheet of moisture-permeable material to each of two faces of each length, allowing the moisture to escape but sheltering the timber from the action of the air, heat being applied by circulating hot air between adjacent layers of timber. Pieces of timber 1 are disposed side-by-side and covers 2 of porous material such as cork, felt, &c. are placed in contact with the faces of the timber extending in the direction of the grain and the layers thus formed are kept apart by corrugated metal sheets 4 or metal tubes, the slack being clamped together by irons 5 connected by ties 6. The ambient atmosphere or hot air circulates freely between the layers and removes moisture permeating the porous covers. Water passes from the timber into the covers and evaporates from the outer surface thereof but as the timber face is shielded from the air it remains moist until the interior of the timber is dry, said to prevent shrinking and cracking. The vapour atmosphere formed between the timber and the porous cover contains in addition to water vapour, methyl alcohol, or the vapour of resins, oils or other organic substances contained in the timber. Heating is carried out in the range 90-110‹ C., but the maximum and minimum temperatures desirable are given as 130‹ and 60‹ C. respectively.

Title: Improvements in or relating to safety devices for oil immersed electric apparatus such as transformers
IPC: H01F27/14
Filed: 1951-03-15
Abstract: 684,140. Transformers. SOC. SAVOI. SIENNE DE CONSTRUCTIONS ELECTRIQUES. March 15, 1951 [March 20, 1950], No. 6273/51. Addition to 660,181. Class 38 (ii). A protection device for oil-filled transformers comprises a reservoir R arranged above a tank A, and includes gas-detecting means B mounted in a pipe b giving connection between the highest point in the tank A and the space in the reservoir R above the maximum oil level, together with a second pipe c, of large section compared with pipe b, which is connected to the cover of the tank A and which is closed by a frangible diaphragm D and a third pipe e, of small section compared with pipe c, affording connection between the lower part of the tank A and the lower part of the reservoir R. If a fault occurs in the transformer causing a sudden displacement of oil in the tank, the oil penetrates into the reservoir by way of orifices d. A more violent movement of oil will burst the diaphragm D to avoid excessive pressures in the tank D, the movable curved portion of the pipe c directing the oil away from danger. The valve C prevents normal circulation of hot oil due to convection, but does not provide appreciable impedance to voilent movement of oil, and since the pipe c is short the inertia of the oil is low and discharge takes place with a minimum of difficulty. The function of pipes e and f are as in the parent Specification, to which reference is made.
