  • Patent number: 7923227
    Abstract: A stable system for producing liquid products such as ethanol, butanol and other chemicals from syngas components contacts CO or a mixture of CO2 and H2 with a hydrophilic membrane under anaerobic conditions and transfers these components into contact with microorganisms contained as a biofilm on the membrane. Maintaining the microorganisms as a biolayer on the surface of the membrane facilitates cleaning of the membrane surface that retains the biofilm. In addition the shell gas space that surrounds the membranes may be flooded to reduce or remove the biofilm. Agitation of the liquid, by for example the bubbling of gas in the surrounding shell space, can fully or partially remove the biofilm from the membrane.

  • Patent number: 7896956
    Abstract: A filter regeneration apparatus of a coal gasification system having a filter for capturing char (unburned matter) present in exhaust gas at an exhaust gas passage communicating with exhaust gas source including a coal gasification furnace, fills the filter container with inactive gas having oxygen concentration of less than 5 vol. % and heat the filter to a target temperature of 400 to 450° C. and feed ashing gas having oxygen concentration of 5 to 15 vol. %, thereby ashing char in the filter. This method and apparatus achieve ashing of char in a safe manner and shortens the time of regenerating the filter by controlling the oxygen concentration in the ashing gas and the filter temperature constantly to reach preset target values.

  • Patent number: 7892302
    Abstract: A process and system is provided for briquetting particulate matter such as moisture-containing bituminous and sub-bituminous coal. This process includes partially drying the particulate matter and feeding, the partially dried particulate matter to a briquetting apparatus under conditions such that water vapor is released from the particulate matter during feeding. The particulate matter is passed through briquette forming rollers to form briquettes. The released water vapor substantially displaces or prevents the ingress of a large proportion of other gaseous components from the atmosphere surrounding and/or intermixed with the particulate matter. The particulate matter that is fed to the briquetting apparatus is surrounded by and intermixed with a gaseous component containing 70 to 100% by volume of water vapor at the point where it enters the briquette-forming part of the briquetting apparatus.

  • Patent number: 7892839
    Abstract: In order to check the hermeticity of a closed cavity of at least one micrometric component, said component includes a structure made over or in one portion of a substrate, a cap fixed to one zone of the substrate to protect the structure, and an indicator element whose optical or electrical properties change in the presence of a reactive fluid. The indicator element may be a copper layer for an optical check or a palladium resistor for an electrical check. The micrometric component is placed in a container which is then hermetically closed. This container is filled with a reactive fluid under pressure, which is oxygen for the optical check and hydrogen for the electrical check. The component in the container is subjected to a reactive fluid pressure higher than 10 bars for a determined time period, and to thermal (T>100° C.) or optical (?<500 nm) activation. After this time period, an optical or electrical check of the indicator element determines the hermeticity of said cavity.

  • Patent number: 7887757
    Abstract: An apparatus for storing and dispensing a test strip includes a container configured to store a stack of test strips. The container maintains appropriate environmental conditions, such as humidity, for storing the test strips. An engaging member is disposed in the container and is adapted to contact one test strip of the stack of test strips. An actuator actuates the engaging member to dispense the one test strip from the container. Since one test strip is dispensed at a time, the remaining test strips are not handled by the user. Accordingly, the unused test strips remain free of contaminants such as naturally occurring oils on the user's hand.

  • Patent number: 7875447
    Abstract: To provide an inexpensive cell incubator for a single cell operation supporting robot having the markers (first and second feature points) required to transform the position of a cell detected on a table coordinate system into a position on the intrinsic coordinate system of the cell incubator. First and second feature points are formed on a film-like feature point setup chip which is then stuck to the cell incubator body such as a conventional dish, thus constituting a cell incubator. Since manufacture of a new die for forming the first and second feature points directly on the cell incubator body is not required, an inexpensive cell incubator for a single cell operation supporting robot can be provided.
