Patent FR-2730732-A1 (FR)
Inventor: FAUCONET MICHEL
IPC: C07C67/08
Filed: 1995-02-17
Abstract: Utilisation, as an ester, of acetic acid contained in the light head fraction obtd. in purificn. of acrylic acid, and contg. acetic acid, acrylic acid, formic acid and water, involves reacting this mixt. with a 4-8C prim. or sec. mono-alcohol, in presence of an acid as catalyst and/or a polymerisation inhibitor. Water formed in the esterification is entrained continuously by distn. in a column, as a heteroazeotropic mixt. with the alcohol. When the acetic, acrylic and formic acids have been converted to esters, purificn. is carried out by (a) reacting the crude mixt. recovered at the end of the esterificn. with an aq. basic soln., to neutralise the catalyst and traces of acetic, acrylic and formic acids, and at the same time, to cause selective saponification of alkyl formate formed in the esterificn., (b) sepg. the heterogeneous mixt., in a decanter, into a lower aq. phase, which is rejected, and an upper organic phase, (c) distilling the organic phase in a column, to recover at the head a light fraction comprising a mixt. of excess alcohol and part of the alkyl acetate, and at the foot a mixt. comprising the alkyl acetate removed at the head and heavy prods., and (d) distilling, in a column, the effluent recovered at the foot of the column in stage (c), to recover, at the head, pure alkyl acetate, and at the foot, heavy prods. comprising mainly alkyl acrylate part of the alkyl acetate.

Title: Simulation chamber for determining effect of radiation from star on satellite
Inventor: GUIDON MICHEL
IPC: B64G7/00
Filed: 1995-12-21
Abstract: The spacecraft or its model (S) is placed in an enclosure (2) surrounded by an insulating wall (3) through which a refrigerating liquid flows (4) to isolate the chamber from the ambient heat. A group of electrically conducting rings (5) is mounted concentrically within the enclosure, each contributing to the provision of radiant energy within the enclosure directed towards the spacecraft. Electrical connections (6) for the rings are made through the insulating wall to electrical sources (7) operating independently, so that each ring is subject to a different voltage and thus dissipating a different heat energy. The number of rings depends on the required accuracy of the simulation. The spacecraft may also be illuminated by a beam of laser light (9) through a window (8) in the insulating wall, the wavelength of this light being complementary to the IR radiation from the electric rings.

Title: Colour digital camera using photomultiplier coupled to optical fibre
IPC: H04N3/08
Filed: 1996-11-06
Abstract: The optical system (30) forms an image of an object (28) in its focal plane (32). A rotating polygonal mirror turns about an axis perpendicular to the direction of sweep and to the direction of the optical system to sweep across the end (42) of the fibre (44). The coloured image may be obtained by using three optical fibres and associated photomultipliers responding to the colours, red, green, blue, perhaps with a fourth fibre to signal luminosity.  The signal from the photomultiplier is connected to an A-to-D converter (48), and a calculator (50) such as a microcomputer to reform the image from the sweep signal. A conventional drive motor can provide the sweep in the perpendicular direction.

IPC: C12P19/04
Filed: 1997-10-27
Abstract: Preparation of a concentrate of proanthocyanidine oligomers (I) by fermenting an extract of the bark of Schinopsis lorenzii, and the use of (I) in cosmetic, pharmaceutical, agroalimentary, dietetic and chemical compositions. The extract of Schinopsis lorenzii (red quebracho, fam. Anacardiaceae) is widely used in the tanning industry and is commercially available. It may be obtained by any extraction process from the bark of the tree. This is fermented using a strain of the fungus Aspergillus niger, which process concentrates the extract into proanthocyanidine oligomers by eliminating other components, especially sugars and organic acids. It further polymerizes the monomers and dimers and de-condenses catechins. The final product (I) contains a minimum of 95% proanthocyanidine oligomers. This may be dried by spraying, evaporation, or lyophilization or used in liquid form, either encapsulated or emulsified, or absorbed onto a solid. Formulated compositions may be administered by any route.  Solid formulations preferably contain 0.01 - 15% (I), especially 0.1 - 2.5%, while capsules preferably contain 0.01 - 25% (I), especially 0.5 - 10%.
