Title: Method for the production of cellulose fibre tissues of antimicrobial effect
Inventor: DIMOV KIRIL D
IPC: D03D15/00
Filed: 1990-09-24
Abstract: The extracted fabric may be used for preparing working clothes for the needs of veterinary medicine and animal breeding. They have an improved resistance to microbial infections under multiple wet treatment. The method focuses on the treatment of non-dyed fabric with potassium or sodium salt of 5,7-dichlorine-8-hydroxyquinoline, in concentrations of 0,5-2 g/l, with fluid coefficient 15-20, at temperatures between 60 and 80 degrees C, for 20 to 40 minutes. Then follows treatment with dimethylol ethylene carbamide or dimethylol dihydroxy ethylene carbamide in concentrations between 60 and 100 g/l, in the presence of a catalyst (magnesium chloride 7-10) for 3 to 5 minutes, drying at 100 to 110 degrees C. Then there is thermo-fixation at 140 to 160 degrees C, for 5 to 10 minutes; washing with anion-active detergent in concentrations of 2 g/l at 70 to 80 degrees C, for 15 to 20 minutes; and, finally, washing with soft water at room temperature. After extracting the dried fabric, the treatment with 5,7-dichlor-8-hydroxyquinolyn is carried out simultaneously with the dying at liquid coefficient 15-20 and temperature 80-90 degrees C, for 20 to 30 minutes. Meanwhile, the remaining conditions are as if dying with direct dyes. Then follows the wring-out and treatment with solution of copper complex in concentrations of 2 g/l at room temperature for 30 minutes.

Title: Diagnostic serologique de la maladie de chagas
Inventor: RAJA GABAGLIA TRAVASSOS LUIZ R
IPC: A61K39/00
Filed: 1998-02-16
Abstract: L'invention concerne un procédé par chimiluminescence (CL)-ELISA avec des antigènes purifiés et complexes de Trypanosoma cruzi permettant de diagnostiquer de manière spécifique et sensible la maladie de Chagas chez des patients et dans des échantillons sanguins. Les préparations utilisées sont un antigène spécifique trypomastigote (A & T) et un extrait d'épimastigote (EpEx) permettant de réguler la sensibilité. La forte sensibilité du procédé CL-ELISA permet une utilisation de quantité extrêmement petite d'antigène et une dilution de sérum dans des tests de routine de 1:2000, réduisant au minimum ainsi les réactions non spécifiques ou faux-positifs. L'utilisation de l'antigène purifié A & T élimine les réactivités croisées avec d'autres agents d'infection, détecte l'infection active et permet de surveiller la chimiothérapie chez les patients chroniques. L'utilisation de la préparation antigène EpEx ne confirme pas seulement les résultats positifs avec A & T mais suggère, lors de divergences, d'autres infections telles que la leishmaniose. Comparé à d'autres tests courants utilisés dans les banques de sang principales, le procédé CL-ELISA avec les antigènes A & T et EpEx, testé en parallèle, s'est avéré nettement plus efficace en éliminant des résultats indéterminés ou en augmentant les statistiques d'échantillons positifs diagnostiqués.

Abstract: The steering wheel (10) of the vehicle of the invention is comprised of a plate (40) mounted in an appropriate annular guide (42) integral with the suspension arm (17) of the vehicle, said plate carrying a second roller bearing (24) fixed excentrically to the plate. The exterior element of the roller bearing is integral with the plate (40) and the integral element of the roller bearing is linked to the wheel (10). An electric motor (47) may drive a screw (49) and, as a result, makes the plate (40) pivot about its axis (41). Thereby, the pilot may modify the offset of the wheel (10), in other words displace the median axis (46) in either side from its central position. As a consequence, the road holding and the stability of the vehicle are improved.
