Patent SE-310671-B (SE)
Inventor: WETTSTEIN A
IPC: C07J5/00
Filed: 1961-07-13
Abstract: The invention comprises (1) a process for the preparation of a 6b ,19-oxido-steroid or the lactone of a 6b -hydroxy-steroid-19-acid, wherein a 19-unsubstituted 6b -hydroxy-steroid is treated in a non-polar solvent with a compound capable of liberating monovalent positive chlorine, bromine or iodine, and, when the lactone is required, the oxido-steroid is oxidized with ruthenium tetroxide or chromic acid or an oxidizing derivative thereof; (2) 6b ,19-oxido-steroids; and (3) the 19,6b -lactones of 6b -hydroxy-steroid-19-acids containing a 5a -halogen atom, a 5-hydroxy group or D 4-3-oxo grouping. The process may be applied to steroids of the androstane, pregnane, cholane, cholestane, stigmastane, spirostane and cardanolide series which may contain free ketalized or enolized oxo groups, esterified or etherified hydroxyl groups, alkyl groups, halogen atoms, oxido or lactone groups or double bonds in one or more positions in the ring-system or 17-side chain. Suitable halogen-containing reagents are N-halo-amides and -imides, cyanogen halides, alkyl or acyl hypohalites, iodine and iodine halides. Acyloxy groups in the products may be hydrolysed before or after the oxidation process, and resulting hydroxy groups oxidized to keto groups.  D 4-double bonds may be introduced by bromination and dehydrobromination, or 5a -(hydroxy or halogen)-3-ketones may be treated with alkaline agents or acid to give D 4-3-ketones. 17-Oxo-androstane products may be converted to the corresponding 17b -hydroxy-17a -hydrocarbon-compounds with metal-hydrocarbon reagents, or they may be reduced to the 17b -hydroxy compounds, with or without concomitant reduction of a 3-keto group which, if it is reduced, may then be re-oxidized. 17a - and/or 21-hydroxyl groups may be introduced into 20-keto pregnanes by conventional methods, and hydroxyl groups may be esterified. Spirostanes may be degraded via furostenes to D 16-20-oxo-pregnens.  Many detailed examples illustrate the processes of the invention and these optional processes.  5a  - chloro - 6b  - hydroxy - steroid starting materials are prepared from the corresponding D 5-steroids and hypochlorous acid.  The cyclic 3a ,5a -carbonate of 3a ,5a ,6b -trihydroxy - 20 - oxo - pregnane is prepared from the triol and phosgene.  The 18,20-lactone of D 5-3b  - acetoxy - 20b  - hydroxy - pregnene - 18 - acid is prepared by treating D 5-3b -acetoxy-20b -hydroxy-pregnen with lead tetraacetate and iodine and oxidizing the product.  3b ,17a - diacetoxy - 6 - oxo - androstane is a by-product in the treatment of 3b ,17a -diacetoxy - 6b  - hydroxy - androstane with mercuric or silver acetate and iodine.  Specifications 994,747 and 994,749 are referred to.
Patent SE-303122-B (SE)
Inventor: LAUCHENAUER A
IPC: D06M13/12
Filed: 1963-07-05
Abstract: Textile materials comprising cellulosic fibres, e.g. cotton yarns and fabrics, are crease-proofed and given improved dimensional stability by producing on them, preferably when they are in an at least slightly swollen state, a rearrangement of the yarns and fibres thereof by uniformly stretching them by at least 30% of their extension at break in the stretched direction, the stretching being carried out in small to infinitely small areas by p  exerting mechanical pull between points which are at a small to infinitely small distance from each other, and then crosslinking the cellulosic fibre material.  The stretching which may be carried out at room or elevated temperatures may be effected by causing the material to form curves of small length perpendicular to its original surface to orginal dimensions measured in that plane remaining substantially unchanged, by means of pairs of bowls or plates with surface structures arranged at a small distance from each other the surface structures consisting of ridges in one surface alternating with grooves in the other, by pressing the material between two elastic bodies or one elastic and one inelastic or less elastic body, e.g. bowls, belts, blankets or plates, so that the material is stretched in the desired directions or by stretching the material between bowls or other bodies having differing surface speeds one of which preferably has a relatively high friction coefficient towards the textile material.  Stretching may be effected during, after or prior to washing, bleaching, dyeing or caustic treatments or in the presence of the cross-linking agents and may be carried out in a series of steps.  Crosslinking may be effected by treatment with synthetic resin precondensates of formaldehyde, glyoxel or acrolein with urea, cyclic alkylene ureas, ureino or triazones aldehydes, acetates, enol ethers, di-or polyfunctional compounds containing epoxy-isocyanate- or vinylsulpho groups, polyhalides, halohydrino, dicarboxylic acids, sulphonium, phosphorium and oxanium compounds or reaction products of ketones with aldehydes which are applied with acid, basic potentially acid or basic catalysts, radical producing compounds or radiation, polyethylene softeners, dyestuffs and pigments, followed by drying and curing. Alternatively cross-linking may be effected by irradiation, substitution reactions, graft polymer formation, formation of polymers in situ or depostion of polymers within the fibres. Crosslinking may be carried out in several steps. Stretching may be carried out at a small angle to the yarns to be stretched. Prior to or after stretching the materials may be subjected to mechanical or chemical shrinking.

Title: Ladle for the chlorination of aluminium alloys,for removing magnesium
Inventor: BRIOLLE EMILE
IPC: C22C1/02
Filed: 1985-07-26
Abstract: The present invention relates to a ladle for the chlorination in co-flow mode of aluminium alloys in a molten state. It is divided by a vertical partition (6) which, with the bottom, leaves a space (7) for the flow of the metal, into a feed compartment (8) and a treatment compartment (9) in which a chlorinated gas distributor rotor (10) is immersed. It is characterized in that the treatment compartment is closed at its base by a horizontal wall (13) which extends at the level of the bottom of the partition and which is apertured at its center by an opening whose axis coincides with the axis of rotation of the rotor. It is used in the removal of magnesium from aluminium alloys and, with ladles of a capacity of close to 1 m3 and which can therefore be easily maneuvered, it makes it possible to attain treatment capacities of the order of 20 T/hour with suitable levels of efficiency in regard to the removal of magnesium.

Title: Digital information recording media and method of using same
Inventor: NOHR RONALD SINCLAIR
IPC: C09B67/00
Filed: 1996-06-03
Abstract: A digital information recording media which includes a recording layer comprising a light-stable colored composition which composition is mutable or decolorizable upon exposure to a specific wavelength of ultraviolet radiation. The light-stable colored composition includes a colorant and an ultraviolet radiation transorber. The colorant, in the presence of the radiation transorber, is adapted, upon exposure of the transorber to specific, narrow bandwidth ultraviolet radiation, to be mutable. The radiation transorber also imparts light-stability to the colorant so that the colorant does not fade when exposed to sunlight or artificial light. The ultraviolet radiation transorber is adapted to absorb radiation and interact with the colorant to effect the irreversible mutation of the colorant. Especially useful radiation is incoherent, pulsed ultraviolet radiation produced by a dielectric barrier discharge excimer lamp or coherent, pulse radiation produced by an excimer laser. In another embodiment, the colored composition which comprises a colorant and an ultraviolet radiation transorber may also contain a molecular includant having a chemical structure which defines at least one cavity. Each of the colorant and radiation transorber is associated with the molecular includant. In some embodiments, the colorant is at least partially included within a cavity of the molecular includant and the ultraviolet radiation transorber is associated with the molecular includant outside of the cavity. In other embodiments, the radiation transorber is covalently coupled to the molecular includant.
