Abstract: The present invention improves the oxidation resistance of an ultrafine metal powder for use in the internal electrode of a multilayer ceramic capacitance and suppresses an increase in the thickness of a metal internal electrode film resulting from the spheroidization of the molten metal under surface tension during the formation of the metal internal electrode film. The ultrafine metal powder has a sulfur-containing compound of not less than one element selected from the group consisting of Y, Zr, and La present on the surface of the particle thereof and is produced by performing an ultrafine metal powder purification step of dispersing the ultrafine metal powder,in a slurry, a surface treatment step of adding an aqueous solution containing a sulfate of not less than one element selected from the group consisting of Y, Zr, and La to the slurry to form the compound on the surface of the metal particle, a filtering step, and a drying step.

Title: An ultra high strength steel composition, the process of production of an ultra high strength steel product and the product obtained
Inventor: VANDEPUTTE SVEN
IPC: C22C38/14
Filed: 2002-08-28
Granted: 2012-03-20
Abstract: The present invention is related to a steel composition, a process for producing a steel product having said composition, and said steel product itself. According to the invention, a cold-rolled, possibly hot dip galvanised steel sheet is produced with thicknesses lower than 1mm, and tensile strengths between 800MPa and 1600MPa, while the A80 elongation is between 5 and 17%, depending on the process parameters. The composition is such that these high strength levels may be obtained, while maintaining good formability and optimal coating quality after galvanising. The invention is equally related to a hot rolled product of the same composition, with higher thickness (typically about 2mm) and excellent coating quality after galvanising.

IPC: C12N9/58

Granted: 2013-01-22
Abstract: The stabilization of biomaterials such as proteins in a nominally dry, hydrophilic glassy matrix is vastly improved by the addition of an appropriate amount of a small-molecule pasticizer such as a glycol or DMSO to the formulation, while maintaining a glass transition temperature (Tg) that is above the storage temperature. By plasticizing the glasses, their ability to preserve proteins is improved by as much as 100 times over the unplasticized glass at room temperature. The plasticizer confers the greatest beneficial effect when it is dynamically coupled into the bulk glass, and this coupling occurs over a fairly narrow range of plasticizer concentration. Methods are described in which a small-molecule plasticizer can be incorporated into a glass made of much larger molecules (e.g. a polymeric glass), with desired dynamic coupling, via a molecule that is believed to act as a dynamic linker. Protein preservation data was obtained from two enzymes, horseradish peroxidase (HRP) and alcohol dehydrogenase (ADH).

Abstract: A method and product is disclosed which provides emulsion stability and filtration control to invert emulsion drilling fluids. The product comprises a blend of a carboxylic acid terminated polyamide and a mixture produced by the Diels-Alder reaction of dienophiles, preferably carboxylic acids, polycarboxylic acids, acid anhydrides, or combinations or mixes thereof, with a mixture of fatty acids and resin acids. The product is extremely effective, decreasing by about two-thirds the amount of emulsifier generally required to formulate an effective drilling fluid. The product also greatly reduces and in many cases eliminates the need for conventional fluid loss additives, and additionally provides electrical stability. Moreover, the product has a pour point as low as about 20 degrees Fahrenheit with minimal solvents, thereby eliminating the need to ship large amounts of inert material for use, and may be transported in a highly active state.

Abstract: The static and electrostatic interaction energy fields between probe atoms and the atoms of a topomerically aligned fragment placed in a three-dimensional grid may be used to derive a CoMFA model. The topomeric CoMFA model coefficients may be used to predict partial activity values for fragments not derived from molecules of the activity series. The partial activities can be summed to provide a predicted activity for all fragment positions of the activity series molecules. A Virtual Library in which topomerically aligned fragments are associated with their respective steric and electrostatic interaction energies can be searched for fragments similar in shape to the fragments derived from the molecules of the activity series. The identified fragments can be used with the topomeric CoMFA coefficients to predict their activity if used in the molecular activity series.

Title: Compresseur de gaz haute pression et methode d'utilisation
Inventor: HILGER ULRICH
IPC: F04B35/01
Filed: 2005-08-04
Granted: 2007-04-24
Abstract: Un compresseur à gaz à haute pression comprend un piston entrainé par une came à simple effet avec une chambre de compensation de pression placée entre le piston et la came. Un ensemble de poussoir à galets transmet un mouvement alternatif de la came au piston. Un gaz sous pression peut être dirigé vers la chambre de compensation de pression pour compenser une partie des forces agissant sur le piston en raison de la pression du gaz dans la chambre de compression, réduisant ainsi la pression hertzienne entre le poussoir à galets et la came. En outre, l'efficacité et la durabilité globales peuvent être améliorées en réduisant la friction entre les composants du compresseur, par exemple en utilisant des revêtements en couches minces afin de réduire les coefficients de frottement, des systèmes de lubrification sous pression d'huile, et un diamètre d'alésage de cylindre supérieur afin que les rapports de course des pistons en réduisent la vitesse. La durée de vie des joints étanches aux gaz et l'efficacité de compression peuvent également être améliorées par des stratégies de gestion thermique, y compris des doublures de cylindres de compresseur refroidies par liquide et l'utilisation d'échangeurs entre les étapes de compression. Enfin, l'emploi d'une soupape d'aspiration de type champignon et la réduction du volume parasite dans la chambre de compression peuvent également améliorer le rendement volumétrique du compresseur.

Abstract: A system diagnostic mode is provided for a security central station receiver that monitors the operations of a large number of individual security systems over a large number of telephone lines. The system diagnostic mode provides the receiver with the capability to test itself for proper operation after it has been initially installed, or on a repeated basis thereafter, to ensure that the receiver at the security central station is fully operational. A plurality of line cards are designed to serve and interface with the large number of telephone lines. The auto test diagnostic mode tests the operation of the central station receiver, and is programmed to automatically dial into each of the plurality of line cards and to send to each line card a number of preformatted test signals using standard reporting formats that are generated by the auto test diagnostic mode. The auto test diagnostic mode is preferably provided on a test line card shat generates the preformatted test signals. After the test is completed, the auto test diagnostic mode routes a report on the results of the preformatted tests to an output of the security central station receiver such as an automation system.

Abstract: The two polystyrene panels of the Insulated Concrete Wall Forming System are tied and held in a parallel relationship by polypropylene bridging webs to provide space between the panels for placement reinforced concrete. Each bridging web is comprised of three parts, namely two identical end-sections and one central section. Each of the end-sections is embedded into one of the polystyrene panels, the central section is inserted into each embedded end-section through complicated sets of hinges, bridging and anchoring the polystyrene panels into a discrete wall-form component (a block). The hinge section of the embedded bridging webs projects out of the polystyrene panels, allowing for the the movement of the two panels from a full extension equal to the width of the central-section to a completely collapsed position during transportation. The embedded end-section of the bridging web is designed so that it can be inexpensively mass produced with a simple injection mould, without any additional intermediary procedure for creating a tubular hinges.  This design characteristic of these bridging webs is unique because it facilitates inexpensive mass production of such webs, and also, because of the two hinges, it allows the collapse of the two panels during transportation thus reducing the shipping costs.
