  • Patent number: 7875090
    Abstract: Disclosed are a method and a corresponding apparatus for converting a biomass reactant into synthesis gas. The method includes the steps of (1) heating biomass in a first molten liquid bath at a first temperature, wherein the first temperature is at least about 100° C., but less than the decomposition temperature of the biomass, wherein gas comprising water is evaporated and air is pressed from the biomass, thereby yielding dried biomass with minimal air content. (2) Recapturing the moisture evaporated from the biomass in step 1 for use in the process gas. (3) Heating the dried biomass in a second molten liquid bath at a second temperature, wherein the second temperature is sufficiently high to cause flash pyrolysis of the dried biomass, thereby yielding product gases, tar, and char. (4) Inserting recaptured steam into the process gas, which may optionally include external natural gas or hydrogen gas or recycled syngas for mixing and reforming with tar and non-condensable gases.

  • Patent number: 7846114
    Abstract: A compression sleeve (10) has twelve inflatable cells (13) to be wrapped around a limb. The cells (13) are inflated to set pressures and duration by a fluid source. The cells (13) are numbered (1) to (12), with (1) being at the toe, or the wrist, and (12) being at the thigh, or the shoulder. In use, the inflation sequence begins with a peristaltic wave at cell (1) and finishes at cell (12). Then cell (12) is inflated and deflated 5 times, then cell (11) is inflated and deflated 5 times in the same way as cell (12), followed by a single peristaltic wave beginning at cell (12) to cell (11). This compression regime is repeated along the compression sleeve until cell (1) is inflated and deflated (5) times followed by a peristaltic wave from cell (1) to cell (12). The described compression sequence is particularly useful for lymphatic drainage.
