Abstract: The present invention relates to a final drug product comprising coagulation factor VIII in an aqueous solution with a reduced concentration of oxygen. In this way, the factor VIII activity can be retained during storage to a surprisingly high degree. The factor VIII  activity can be retained for a prolonged period of time, if the final drug product further comprises an inert gas and/or an antioxidant. The present invention also relates to processes for reducing the oxygen concentration of the aqueous solution, and a method for improving the stability of factor VIII in an aqueous solution by storing the solution under an inert gas atmosphere. By the present invention it is possible to retain at least 50 % of the initial activity of factor VIII after storage for at least 6 months at a temperature of 2 to 10 °C and a pH of the solution of 6.5 to 8.5.

Abstract: Provided is a process for catalytic reforming a hydrocarbon feedstock containing at least 20 ppbw sulfur. The process comprises passing the hydrocarbon feedstock through at least two serially connected reforming zones, with each zone containing a highly sulfur sensitive reforming catalyst. The catalyst in the first reforming zone is more frequently regenerated than the catalyst in the second reforming zone. The result is a highly efficient and simplified process for reforming a sulfur contaminated hydrocarbon feedstock. The process basically employs a minor portion of the highly sulfur sensitive reforming catalyst as both the reforming catalyst and a sulfur removal agent.

Abstract: A stabilized spray displacement tin plating process of copper printed circuit innerlayers is disclosed for the manufacture of multilayer printed circuit boards.  During prolonged use of spray tin plating, the plating solution becomes saturated with cupurous thiourea complex which precipitates interfering with spray nozzles and other mechanical components.  The tin plating solution is stabilized by removing portions from the reservoir before saturation is reached, selectively precipitating the thiourea complex, and returning the remaining solution back to the reservoir. The precipitated cupurous thiourea complex is redissolved in acid and either disposed of by conventional waste treatment or the acid solution can be electrowinned to reclaim copper and oxidize thiourea to form a more acceptable acid solution for waste treatment. Preferably,the thiourea is isolated from the anode during electrowinning, so that the acid thiourea solution formed may be used to partially replenish the tin plating solution in the reservoir. By such periodic removal of the complex, the plating bath is stabilized and its useful life is extended dramatically.

Inventor: YANO MUTSUMI
IPC: C01G51/04
Filed: 1997-02-06
Granted: 2004-11-16
Abstract: A non-sintered nickel electrode for use in alkaline storage batteries is provided. An active material of the electrode takes the form of composite particles consisting of grains of nickel hydroxide or grains mainly constituted by nickel hydroxide, each of which has a surface formed with an electric conduction layer consisting of a cobalt compound containing 0.1 to 10 % by weight sodium. The electrode is thereby adapted to make an active material available in a high degree because the pulverulent active material consists of grains, each of which is coated with an electric conduction layer having a high electric conductivity. Because the electrode is non-sintered, the highly porous substrate allows an active material having a relatively large bulk density to be used during manufacture. The presence of sodium in the electric conduction layer improves specific electric conductivity of the electrode relative to other non-sintered nickel electrodes.

Abstract: L'invention concerne un convertisseur de courant équipé d'une paire d'interrupteurs établis chacun entre des sources de tensions continues constantes positives et négatives, et d'un noeud de sortie commun relié à une charge. Un modulateur ouvre et ferme les interrupteurs selon une séquence où il se produit une opposition mutuelle, au noeud de sortie commun, des courants électriques commandés par les interrupteurs, et une sommation desdits courants à ce noeud de sortie. Le modulateur comporte un générateur de signaux triangulaires et des comparateurs couplés à un amplificateur d'erreurs dans le but de fournir une tension d'interruption de support aux comparateurs. Les comparateurs activent les interrupteurs de commande en réponse aux signaux triangulaires produits par le générateur sus-mentionné à un niveau supérieur et inférieur par rapport aux niveaux de référence. On régule les phénomènes d'interlignage et de chevauchement propres aux convertisseurs en faisant varier le niveau de la polarisation en courant continu des signaux triangulaires.
