  • Patent number: 8394631
    Abstract: The present invention provides a fluid exchange cell culture technique and tissue repair cells (TRCs) made by these methods, as well as methods using these cells. The method includes a new wash step which increases the tissue repair properties of the TRCs of the invention. This wash step allows for the production of TRC populations with greater tissue repair and anti-inflammatory capabilities. Embodiments of the present invention include a post-culture process for cultured cells that preferably includes the steps of: a wash process for removing unwanted residual culture components, a volume reduction process, and a harvesting process to remove cultured cells. Preferably, all these steps are performed within a aseptically closed cell culture chamber by implementing a separation method that minimizes mechanical disruption of the cells and is simple to automate. The harvested cells may then be concentrated to a final volume for the intended use.

  • Publication number: 20090179541
    Abstract: Vacuum insulation panels and methods for making vacuum insulation panels. The panels include first and second spaced-apart sidewalls, where at least one of the sidewalls has a very smooth surface. The panels are particularly useful as insulation in applications where a smooth and aesthetically acceptable surface is required, such as in a refrigeration appliance. A method for making a vacuum insulation panel can include placing an insulative core material and a liner within a barrier envelope defining an enclosure, evacuating the enclosure, and sealing the envelope to form the vacuum insulation panel.

  • Publication number: 20090001086
    Abstract: A container insert for providing a thermally insulated enclosure. The container insert includes a bottom panel, side panels and end panels that are interconnected by a plastic backing sheet. The side panels and end panels can be pivoted upwardly to form side walls and end walls. The plastic backing sheet covers the seams between adjacent insulation panels to provide a moisture barrier. The plastic backing sheet can also urge adjacent panels together to reduce the gap between adjacent panels and improve thermal performance.

  • Publication number: 20090000312
    Abstract: A method and apparatus for the rapid cooling of a container and its contents, such as a beverage container. A heat transfer fluid is thermally contacted with the beverage container, where the heat transfer fluid has a temperature of less than 0° C. The heat transfer fluid can be physically separated from the container, such as by flowing the heat transfer fluid through a heat exchanger that surrounds the container. The cooling parameters can be controlled such that the container and its contents are rapidly cooled without freezing of the contents.

  • Patent number: 7143589
    Abstract: A sorption cooling system for providing cooled air to the cabin of a vehicle. The sorption cooling system includes an evaporator, a condenser adapted to fluidly communication with the evaporator, and a plurality of adsorbent beds adapted for fluid communication with the condenser and the evaporator. Each adsorbent bed includes a fluid impermeable casing, desiccant sheets having apertures therethrough, a refrigerant flow path for flowing a refrigerant proximal to a first side of the desiccant sheets, and a coolant flow path for flowing a coolant fluid proximal to a second side of the desiccant sheets. The apertures are a portion of one of the refrigerant and coolant flow paths.

  • Patent number: 6960243
    Abstract: A method and apparatus for the extraction of water from a gas stream, such as atmospheric air. The method includes contacting the gas stream with a porous adsorbent material having a surface modifying agent adsorbed on the surface of a porous support. The surface modifying agent creates a hydrophilic surface for the adsorption of the water. After the water is adsorbed into the pores, the surface modifying agent is selectively desorbed from the surface. The water then evaporates from the pore and can be collected in a condenser. The method and apparatus of the present invention advantageously operate in a substantially isothermal manner, thereby reducing the size and power consumption of the device. The device can advantageously be used to extract potable drinking water from atmospheric air.

  • Patent number: 6858068
    Abstract: A device for adsorbing water vapor from a gas stream. The device can be incorporated with an enclosure or garment in such a manner so as to enable water vapor to be adsorbed, thereby decreasing the relative humidity in the micrlimate surrounding the user. The water adsorption device is light-weight, has a high mass and volumetric energy capacity. A desiccant material is included within the water adsorption device to adsorb water vapor and a phase-change material is located in thermal communication with the desiccant to increase the loading capacity of the desiccant and maintain a cool gas stream by extracting the heat of adsorption from the desiccant.

  • Patent number: 6821554
    Abstract: This invention has enabled a new, simple nanoporous dielectric fabrication method. In general, this invention uses a polyol, such as glycerol, as a solvent. This new method allows both bulk and thin film aerogels to be made without supercritical drying, freeze drying, or a surface modification step before drying. Prior art aerogels have required at least one of these steps to prevent substantial pore collapse during drying. Thus, this invention allows production of nanoporous dielectrics at room temperature and atmospheric pressure, without a separate surface modification step. Although not required to prevent substantial densification, this new method does not exclude the use of supercritical drying or surface modification steps prior to drying. In general, this new method is compatible with most prior art aerogel techniques. Although this new method allows fabrication of aerogels without substantial pore collapse during drying, there may be some permanent shrinkage during aging and/or drying.

  • Patent number: 6734608
    Abstract: A structure suitable for partial or full use in a spacer (24) of a flat-panel display has a porous face (54). The structure may be formed with multiple aggregates (100) of coated particles (102) bonded together in an open manner to form pores (58). A coating (88) consisting primarily of carbon and having a highly uniform thickness may extend into pores of a porous body (46). The coating can be created by removing non-carbon material from carbon-containing species provided along the pores. A solid porous film (82) whose thickness is normally no more than 20 &mgr;m has a resistivity of 108-1014 ohm-cm. A spacer for a flat-panel display contains a support body (80) and an overlying, normally porous, layer (82) whose resistivity is greater parallel to a face of the support body than perpendicular to the body's face.
