  • Patent number: 10041407
    Abstract: The disclosed embodiments relate to a system and method that allows air to be extracted from a plurality of gas turbine engines and fed to a downstream process, even in situations in which one or more of the gas turbine engines are operating in a part load condition. For example, in an embodiment, a method includes monitoring signals representative of a header pressure of a header, or a pressure of extraction air flow from one or more gas turbine engines to the header, or both, and maintaining substantially continuous flows of extraction air from the gas turbine engines to the header. The substantially continuous flows are maintained when the gas turbine engines are under symmetric and asymmetric load conditions.

  • Patent number: 8753440
    Abstract: The present embodiments are directed towards the cooling of a solvent of a gas treatment system using a fluid flow from an air separation unit. In one embodiment, a system is provided that includes an air separation unit. The air separation unit has an air inlet configured to receive an air flow, an oxygen outlet configured to output an oxygen flow, a nitrogen outlet configured to output a nitrogen flow and a cooling system configured to cool the air flow to enable separation of the air flow into the oxygen flow and the nitrogen flow, wherein the cooling system is configured to cool a first solvent of a first gas treatment system.

  • Publication number: 20060255484
    Abstract: A solid state, compression method for fabricating lenses, lens blanks, and lens components from materials ground into fine powders having mechanical properties the make them capable of being formed into cohesive monolithic masses that are low in scattering. The fine powders may be admixtures of host matrix materials and others which, when combined, provide preferred optical properties such as index and dispersion. Parts possessing transmission from within the range from the ultraviolet to the infrared are possible. The method is particularly suited to low temperature formation of aspheric lenses transmissive in the near and far IR.

  • Publication number: 20050264878
    Abstract: A directionally-oriented reflective device is optically coupled to a prism surface in a skin ridge pattern imaging system to reflect illumination light at relatively small angles, along an optical path to an imaging device, so that minimal light is lost from the optical system. Examples of such directionally-oriented reflective devices include, but are not limited to, echelon reflectors, faceted reflective surfaces, retroreflectors, aluminum paint, nacreous pigment, and slightly rough mirror surfaces.

  • Patent number: 6072485
    Abstract: A technique for adapting a GUI which is not able to respond to directional navigation inputs which move a focus by specifying a location and a direction from a location to respond to such navigation inputs. The adaptation is done by means of a function which takes the location and the direction as arguments and moves the focus to the area capable of receiving it that is closest to the location specified in the argument in the direction specified in the argument. The function uses a non-directional navigation technique provided by the GUI to obtain each area which is a candidate for receiving the focus in turn and as each area is received, the function determines whether the area is located in the specified direction relative to the specified location and if the area is, whether it is closer to the specified location than any area as yet found. Once all of the areas have been thus examined, the focus is moved to the closest area.
