Title: Hydrometallurgical recovery of metals from complex ores.
Inventor: O'BRIEN ROBERT N
IPC: C22B3/44
Filed: 1994-01-24
Abstract: A continuous hydrometallurgical process for conversion of ore derived copper and zinc sulfides into recoverable water soluble sulfates is provided. The process comprises: i) contacting the ore derived copper and zinc sulfides with sulfuric acid and with nitric acid to form a reaction mixture in an acidic solution, ii) maintaining the reaction mixture at a temperature in the range of 110 DEG  C. to 170 DEG  C. while continuously mixing the reaction mixture, iii) adding sufficient sulfuric acid and nitric acid to the reaction mixture to form a light precipitate and a dark precipitate in the reaction mixture, the light precipitate comprising water soluble sulfate salts of copper sulfate, zinc sulfate and iron sulfate, and the dark precipitate being water insoluble and comprising mainly elemental sulfur and gangue, iv) introducing a source of oxygen to the reaction mixture to promote oxidation in the presence of the nitric acid, of the sulfides to sulfates and to oxidize gaseous NOx reaction products to regenerate nitric acid for the reaction mixture, v) removing the light and dark precipitates and any entrained acidic solution from the reaction mixture, vi) separating the light and dark precipitate from the acidic solution in preparation for treatment of the light precipitate for recovery of copper sulfate and zinc sulfate from the light precipitate, and vii) recycling the acidic solution to the reaction mixture.

Abstract: Die Farbkontrolle von Produkten wird mit bildgebenden farbtüchtigen Sensoren wie Farbmatrix-, Farbzeilen- oder punktweise arbeitenden Abtastern durchgeführt, indem aus den Signalen dieser Sensoren sowohl für eine Referenz als auch für die Prüflinge jeweils eine oder mehrere mehr dimensionale Histogramme der Farbvektorkomponenten berechnet werden und aus dem Vergleich dieser Histogramme Maße für die Farbabweichung oder Farbübereinstimmung gewonnen werden. Aus den Histogrammen werden vor dem Vergleich automatisch ungültige Stellen, welche Glanzstellen, Schattenzonen oder unsicheren Farbwerten entsprechen, beseitigt. Diese Farbkontrolle kann daher auch für Objekte angewendet werden, deren Oberfläche nicht diffus ist und die durch andere Bildinhalte gestört ist.

Title: Traitement du metal liquide
Inventor: ECKERT C EDWARD
IPC: C22B9/05
Filed: 1994-07-13
Abstract: L'invention concerne une méthode perfectionnée de dispersion d'un agent de traitement dans une masse de métal liquide: un agitateur (6) disperse l'agent dans le métal liquide (8), ce qui augmente l'effort de cisaillement dans le métal liquide et réduit la formation de vortex. Selon cette méthode, une masse de métal liquide (8) entoure un axe (4) comportant un agitateur (6). Un agent de traitement est ajouté à la masse, dans laquelle il est dispersé par rotation de l'agitateur (6) dans un sens donné, puis dans le sens opposé. Le sens de rotation de l'agitateur est régulièrement inversé, ce qui réduit considérablement la formation de vortex autour de l'axe (4) de l'agitateur et augmente l'effort de cisaillement dans la masse. Cette méthode permet d'améliorer le traitement du métal liquide grâce à une meilleure dispersion de l'agent dans la masse.

Abstract: Un distributeur (305) de bandes de ligature permet de distribuer individuellement les bandes (310, 311, 312) selon l'invention pendant une séquence de fonctionnement d'un instrument de ligature. Un boîtier (306) et des segments de piston (307) emboîtés supportent plusieurs bandes de ligature espacées dans le sens axial. La rétraction d'un segment de piston entraîne la distribution d'une bande de ligature et le décalage des bandes restantes vers l'extrémité distale de l'instrument et axialement. Après cette rétraction, le piston est poussé vers l'avant de façon qu'une rétraction ultérieure entraîne la distribution d'une autre bande de ligature. Une aiguille (330) d'injection sclérosante est montée dans une gaine (320) raccordée au segment du piston. Un médecin peut rétracter le piston en même temps que la gaine. De plus, il peut faire avancer l'aiguille d'injection sclérosante dans la gaine pour administrer un agent sclérosant destiné à remplacer la ligature d'une lésion.
