  • Publication number: 20240115418
    Abstract: Devices, systems and methods for removing heat from subcutaneously disposed lipid-rich cells are disclosed. In selected embodiments, suction and/or heat removal sources are coupled to an applicator. The applicator includes a flexible portion and a rigid portion. The rigid portion includes a thermally conductive plate and a frame coupling the thermally conductive plate and the flexible portion. An interior cavity of the applicator is in fluid communication with the suction source, and the frame maintains contiguous engagement between the heat removal source and the thermally conductive plate.

  • Patent number: 9157357
    Abstract: In situations where the demand for syngas is intermittent, a fuel processor is operated to provide a high absolute hydrogen and carbon monoxide production, rather than to give a high fuel-specific hydrogen and carbon monoxide production. When a syngas generator is operated to intermittently produce syngas, a heating process can be performed between periods of syngas demand in order to keep the fuel processor within a desired temperature range. The heating process can comprise various steps or events including performing a heating event, allowing a standby period, and/or performing a carbon conversion event. Carbon formed during the process of converting fuel to syngas can be advantageously converted to maintain the temperature of the fuel processor within a desired range in between periods of syngas demand. A predictive method can be employed to control at least a portion of the heating process.

  • Patent number: 9032708
    Abstract: In situations where the demand for syngas is prolonged, a fuel processor is operated continuously to provide a syngas stream for a prolonged period. The equivalence ratio of reactants supplied to the fuel processor is controlled so that a high fuel-conversion efficiency to hydrogen and carbon monoxide is obtained at temperatures correspondent to carbon production balance, where carbon is formed and gasified at approximately the same rate in the fuel processor.

  • Patent number: 9017140
    Abstract: A CMP polishing pad comprising (a) a polishing layer having a polishing surface and a back surface opposite said polishing surface; said polishing layer having at least one cured opaque thermoset polyurethane region and at least one aperture region; said at least one cured opaque thermoset region has a porosity from about 10% to about 55% by volume; said at least one aperture region having (1) a top opening positioned below the polishing surface, (2) a bottom opening that is co-planar with said back surface and (3) straight line vertical sidewalls extending from said aperture top opening to said aperture bottom opening; said at least one aperture region filled with a cured plug of thermoset polyurethane local area transparency material that has a light transmission of less than 80% at a wavelength from 700 to 710 nanometers and is chemically bonded directly to a thermoset polyurethane opaque area; (b) an aperture-free removable release sheet covering at least a portion of said back surface of the polishing l

  • Patent number: 8747496
    Abstract: A fuel processor for producing a hydrogen-containing product stream from a fuel stream and an oxidant stream, comprises a mixing tube from which the combined fuel and oxidant stream is directed substantially axially into a reaction chamber. The reaction chamber comprises a turn-around chamber and a turn-around wall at one end for re-directing the combined reactant stream, so that in the turn-around chamber the re-directed stream surrounds and is in contact with the combined reactant stream flowing substantially axially in the opposite direction. This design and opposing flow configuration creates a low velocity zone which stabilizes the location of a flame in the fuel processor and offers other advantages.

  • Publication number: 20070021045
    Abstract: The present invention relates to an article for altering a surface of a work piece, or a polishing pad having a window. In particular, the polishing pad includes a polyurethane urea material wherein the polyurethane urea material contains cells which are at least partially filled with gas. The polyurethane urea material can be prepared by combining polyisocyanate and/or polyurethane prepolymer, hydroxyl-containing material, amine-containing material and blowing agent. The polishing pad according to the present invention is useful for polishing articles, and is especially useful for chemical mechanical polishing or planarization of microelectronic and optical electronic devices such as but not limited to semiconductor wafers. The window of the polishing pad is at least partially transparent and thus, can be particularly useful with polishing or planarizing tools that are equipped with through-the-platen wafer metrology.
