Inventor: VICIC JOHN C
IPC: C08K7/28
Filed: 2001-04-13
Abstract: La présente invention concerne un matériau isolant comprenant une résine polymère au polysulfure durcie novolaque. Le matériau est utilisé en tant qu'isolant thermique pour du matériel de production de gaz et d'huile immergé tel que des conduites et du matériel de tête de puits. Afin de réduire la température exothermique maximum générée par la résine lors de son durcissement, des billes de verre creuses sont incorporées dans la résine. La teneur en amines du durcisseur dans une résine classique a été ajustée pour réduire un peu plus la température exothermique maximum. Une matière thixotrope de silice sublimée a également été ajoutée pour accroître la viscosité du mélange. Ces modifications permettent de couler le matériau sous forme de segments épais sans que ces derniers se fissurent, fuient hors du moule ou se dilatent excessivement pendant le durcissement.

Title: Dye-based fuel indicator system for fuel cells
Inventor: MANN L CHRIS
IPC: H01M8/04
Filed: 2003-01-09
Abstract: A means for determining the concentration of a hydrogen-rich fuel in a fuel solution within the anode reservoir (202) of a fuel cell. The fuel concentration is determined using a dye mixture responsive to fuel concentration within a fuel solution. As fuel is consumed, the fuel concentration decreases. As the fuel concentration decreases, the dye changes color. The resulting color changes occur within the anode reservoir (202) of the fuel cell, or within a dye chamber (210) in fluid contact with the anode reservoir (202), and are made visible by a window (204).    A color strip (206) and fuel scale (208) may be included to facilitate fuel concentration determination based on the color of the fuel solution.  Additionally, a valve responsive to dye color may act to control fuel delivery.

Title: Method for testing liquid hydrocarbons using refractive index
Inventor: CHETWYND ROGER
IPC: G01N33/18
Filed: 2003-06-13
Abstract: The present invention comprises an apparatus and method for measuring the content of water in unrefined hydrocarbons by calibrating a capacitance measuring device to match field measurements of refractive index of emulsion of oil and water to linear data (refractive index of oil versus density of oil) published in the public domain. This method provides a basis for converting the output of the capacitance measuring device using the known value of water content and density of two batches of emulsions, one at the upper emulsion density (heavier oil) and one at the lower emulsion density (lighter oil). The output of the probe characterized by the calculated effective dimensions of the probe can be used to calculate the refractive index of the emulsion. An online procedure may be used to calculate the actual density of oil from the density of emulsion as measured by a density measuring device. The density measurement may then be applied to a linear curve fit obtained from the data published in the public domain to calculate the value of the refractive index of the oil. The water content of water in emulsion may then be calculated from a linear equation derived from first principles of physics. The resulting equation is a function of the refractive indices of dry oil, emulsion of oil and water.
