Abstract: 1,068,978. Semi-conductor devices. BROWN, BOVERI & CO. Ltd. April 25, 1966 [April 27, 1965], No. 18000/66. Heading H1K. In a process for treating a thermally oxidized silicon member having a barrier layer with an edge admitting to the surface of the member, the edge of the barrier layer is subjected to electrolytic treatment to increase the reverse voltage of the member. An N-type silicon disc is provided with a P-type zone by diffusing in aluminium, and the edge of the disc is removed mechanically to expose the barrier layer. The disc is then etched in a mixture of nitric, hydrofluoric and acetic acid and oxidized for one hour in dry oxygen. This treatment greatly reduces the reverse voltage. The disc is now immersed in an electrolyte comprising potassium nitrate dissolved in N-methyl acetamide or ethylene glycol, the underside and top of the disc are covered with tubular plungers containing contact members, and a D.C. source is connected between the contact members and a counterelectrode placed in the electrolyte, the disc forming the anode. Alternatively the counterelectrode may be omitted and an A.C. supply connected across the contact members. Treatment is continued for one hour, after which the reverse voltage is found to have been raised to nearly its original value.

Abstract: The invention comprises as new products diacylated tartaric acids of the general formula <FORM:0772215/IV(b)/1> <FORM:0772215/IV(b)/2> wherein R is the radical of an a ,b  unsaturated aliphatic carboxylic acid or the radical of an a ,b  unsaturated carboxylic acid, wherein the a  and the b  carbon atoms are part of a non-aromatic ring.  The preferred products are those in which R is the radical of an a ,b unsaturated aliphatic carboxylic acid which contains not more than 10 carbon atoms, and the radical of an a ,b  unsaturated carboxylic acid in which the a  and b  carbon atoms are part of a non-aromatic six-membered ring, e.g. the radical of an a ,b -unsaturated carboxylic acid in which the a  and the b  carbon atoms are part of a coumarine ring.  The products may be obtained by reacting d or l tartaric acid with the halide of the a -b  carboxylic acid and converting any diacyl tartaric acid anhydride produced into the corresponding acid by treatment with a mildly acting hydrolysing agent.  In examples: (1) coumarine-3-carboxylic acid chloride and d-tartaric are heated at 135-145 DEG  C. in xylene for 3 hours.  The mass is then diluted with benzene and cooled to yield a crystalline precipitate which is filtered off and boiled with benzene to extract coumarine-3-carboxylic acid anhydride whilst the benzene insoluble mass containing the anhydride of the desired di-coumarine-3-carboxylic acid ester of d-tartaric acid is shaken out with acetone and then boiled with 90 per cent acetone to hydrolyse the anhydride to di-coumarine-3-carboxylic acid ester of d-tartaric acid; (2) di-coumarine-3-carboxylic acid ester of l-tartaric acid is obtained by a procedure as in (1) except that l-tartaric acid is used; (3) a mixture of crotonic acid chloride and d-tartaric acid is heated to 110-120 DEG  C. and then to 140-150 DEG  C. to complete the reaction and the excess acid chloride is distilled off.  After cooling, the solidified residue is extracted with petroleum ether and the extract cooled to precipitate dicrotonyl-d-tartaric acid anhydride which is then hydrolysed by boiling with 50 per cent acetone to form di-crotonyl-d-tartaric acid; (4) di-crotonyl-l-tartaric acid is obtained by a procedure as in (3) except that l-tartaric acid is used; (5) di - (b b  - dimethylacryl) - l - tartaric acid is obtained by heating l-tartaric acid with dimethyl acrylic acid chloride at 110 DEG  C. and then at 140 DEG C., cooling, extracting with ligroin, cooling the extract to form a crystalline pulp comprising di-(b b -dimethylacryl)-l-tartaric acid anhydride and hydrolysing the latter by boiling with 94 per cent acetone; (6) di-(b b -dimethylacryl)-d-tartaric acid is obtained by a similar procedure to (5) except that d-tartaric acid is used and 95 per cent acetone is used for the hydrolysis.  The products are stated to be suitable for use in the separation of mixtures of lysergic and isolysergic acid derivatives.  Specification 573,514, [Group IV], is referred to.

Abstract: 909,848. Locating magnetic bodies. UNITED KINGDOM ATOMIC ENERGY AUTHORITY. July 5, 1961 [May 24, 1960], No. 18268/60. Class 37. [Also in Group XL (a)] The position of a permanent magnet with respect to an A.C. energized coil wound on a ferrous core which it maintains just short of saturation, and from which the magnet is isolated by a sealed container, is indicated by the change of inductance of the coil, due to the change of flux through the core, when in the neighbourhood of the magnet. A nuclear reactor shut-down rod, movable in a sealed sleeve of non-magnetic material, has an attached horse-shoe magnet which, in the fully inserted and fully withdrawn positions of the rod, presents its poles to one of a pair of horseshoe shaped iron cores outside the sleeve. Each core has a coil wound over a portion of reduced cross-section, which portion is driven into saturation, with consequent decrease in coil inductance, when the magnet moves into its proximity. The resulting increase in current may operate a relay or position-indicating meter.
