Abstract: Disclosed generally is a coating end structure of dissimilar metallic materials having different characteristics. More specifically, the coating end structure is for example a current-carrying contact or arching contact which is used for, e.g., a power breaker, or a coating end structure of a metal base and a coating material for improving conductivity and heat resistance.      The coating end structure comprises a recessed metal base and a coating material having a smaller or greater rigidity than that of the metal base, to provide a coating structure having a high reliability. When the coating material has a smaller rigidity than the base metal, an angle of the base to a free edge of a coating end portion is at least 120 degree or 55-85 degree. When the coating material has a greater rigidity, the angle is no more than 60 degree or 95-125 degree.

Title: Method of acidizing a subterranean formation with diverting foam or fluid
Inventor: CAWIEZEL KAY C
IPC: E21B43/22
Filed: 2004-07-16
Granted: 2011-07-12
Abstract: A method of acidizing a subterranean formation with a diverting agent composed of a gelled or thickened viscoelastic foam or fluid generated from (i.) an amidoamine oxide gelling agent and (ii.) an acid or foam, water and/or brine. The gelled or thickened foam or fluid may be generated in-situ or introduced directly into the formation by mixing of the amidoamine oxide gelling agent and acid or foam, water and/or brine. As the acid spends, the acidizing fluid thickens. When the acid is further spent, the fluid viscosity declines eventually returning to a low viscosity state, allowing for easy cleanup. The process allows for selective acidizing of less permeable zones of the formation and more uniform stimulation of the hydrocarbon bearing formation.

Abstract: A vent assembly has a base and a single piece cover that is attached to the base to form a housing. A partition inside the housing forms an upper compartment that communicates with an outlet at the rear of the cover and a lower compartment that communicates with an inlet through the base. The compartments communicate via an opening through the partition. The partition provides an exhaust passage from the opening to the outlet at the rear of the cover and a barrier to the flow of water from the outlet back to the opening.  The partition and cover provide a drain passage from the exhaust passage back to the outlet in case water accumulates near the opening. The vent assembly may be static or include a fan unit to provide a powered vent assembly. Either may be used as the hatch of a combined vent and escape hatch assembly.

Title: Primitive and proximal hepatic stem cells
Inventor: REID LOLA
IPC: C12N5/071
Filed: 2003-03-14
Granted: 2019-10-29
Abstract: Hepatic progenitors comprise two populations of human hepatic stem cells, primitive and proximal hepatic stem cells, and two populations of committed progenitors, one for biliary cells and one for hepatocytes. Human primitive hepatic stem cells are a very small fraction of the liver cell population and give rise to proximal hepatic stem cells constituting a much larger fraction of the liver. Human proximal hepatic stem cells give rise to biliary and hepatocyte committed progenitors. Primitive and proximal stem cells are the primary stem cells for the human liver. Human primitive hepatic stem cells may be isolated by immunoselection from human livers or culturing human liver cells under conditions which select for a human primitive hepatic stem cell.  Proximal hepatic stem cells may be isolated by immunoselection, or by culturing human liver cells under conditions which include a developmental factor. Proximal hepatic stem cells may also be isolated by culturing colonies comprising a primitive hepatic stem cell under conditions which include a developmental factor. Resulting compositions may be used for treating liver disorders and for producing bioartificial organs.

Abstract: La présente invention permet de résoudre le problème des artéfacts de pics fantômes qui peuvent parfois se présenter dans les spectromètres de masse qui font appel à un ensemble de barreaux quadripolaire à la fois pour le piégeage et pour l'analyse de masse des ions piégés. Le problème découle de gradients de tension dont la distribution est aléatoire sur la longueur des barreaux. L'invention apporte trois solutions au problème précité. La première approche consiste à améliorer les caractéristiques de conduction des ensembles de barreaux. La seconde approche consiste à appliquer au moins un champ c.c. axial continu à l'ensemble de barreaux quadripolaire de piégeage afin de pousser les ions vers une région prédéterminée du piège, évitant de la sorte les gradients de tension. Une autre approche consiste à appliquer un ou plusieurs champs axiaux discrets afin de créer une ou plusieurs barrières potentielles le long de la dimension axiale du piège (en plus des barrières utilisées pour le piégeage initial des ions). Ces barrières permettent d'empêcher les ions aux gradients de tension différents de s'équilibrer entre eux.
