Abstract: A gas mixture preheated to high temperatures using an oxy-fuel, an oxygen-enriched air-fuel or an air-fuel burner is used to devolatilize and partially oxidize carbonaceous feedstock, thereby producing an active residual char that can be used in applications utilizing activated carbon. Use of hot gas and ground carbonaceous feedstock allows the equipment to be minimized, thereby allowing the activated carbon to be produced at or near points of use, for example the production of activated char at or near utility boilers for use in the reduction of mercury emissions from flue gas streams.

Abstract: Recombinant chimeric antigens comprising unmodified and modified reactive polypeptide fragments of expressed product of the recombinant 56 kDa proteins of multiple strain of scrub typhus, such as Karp, Kato (Ktr56), Gilliam (Gmr56), and TA763 (TAr56). The invention is useful for detecting prior exposure to a number of strains of scrub typhus, based on the strength of reaction toward the chimeric protein and as a component in vaccine formulations and production of immune globulins for passive prophylaxis and immunity in subjects against heterologous infections.

Abstract: The invention relates to a method for the detection of prior exposure to Coxiella. burnetii infection by antibody-based assays using recombinant, immunodominant C. burnetii polypeptides. The invention also relates to the design of biotin or His-tagged C. burnetii proteins useful in the antibody-based assays as standardized antigen reagents.

Abstract: A tank and method for containing a cryogenic liquid in which a purge gas is introduced into an insulation space defined between an outer vessel and an inner vessel to contain insulation material. The inner vessel is used to contain the cryogenic liquid. The purge gas can be cryogenic vapor evolved from the liquid and routed into the insulation space. Control of the purge gas within the insulation space can be provided by a programmable logic controller in which purge gas is vented from the insulation space should the pressure be indicative of a leak within the inner vessel and purge gas is introduced into the insulation space should the pressure be below the ambient to maintain a positive purge gas pressure. An adsorbent bed can also be located within the insulation space to adsorb any moisture.

Abstract: Solid adsorbents, following their use for mercury removal from flue gas, that do not interfere with the ability of air-entraining additives (such as surfactants) to form stable bubbles when added to fly ash containing the adsorbents. The interference is overcome by heating the materials used in the manufacture of the adsorbent so that magnesium hydroxide and/or one or more alkali compounds containing one or more silicate, aluminate, and/or phosphate moiety, added or already present in the materials, binds multivalent cations present in the materials that could otherwise interfere with the surfactant activity.

Abstract: A carrier device used for carrying an optical disk in a manufacturing process is provided. The carrier device includes a base, a first supporting piece and a second supporting piece. The base includes a carrying area whose size is equal to that of the optical disk. The first supporting piece is protruded from the base and located at the center of the carrying area. The second supporting piece is disposed on the base and located in the carrying area. The second supporting piece is separated from the edge of the carrying area at a distance of more than or equal to one fourth of the radius of the carrying area.

Abstract: The present invention provides catalytic adsorbents formed from doping activated carbon with a dispersed halide salt. The catalytic adsorbents provided herein are stable and harmless at room temperature, yet allow for chemical adsorption at elevated temperatures typical of those for flue gas streams. The present invention also provides methods of manufacturing the doped activated carbon adsorbents.

Abstract: The invention relates to adsorbent materials having comparatively high intrinsic adsorption rates. Methods are disclosed whereby such rates can be achieved. In preferred embodiments, the adsorbent is a LiX zeolite material.

Abstract: In using calcium-exchanged forms of zeolite X as selective adsorbents for nitrogen in PSA air separation process, it has been discovered that, particularly under certain temperature and pressure conditions, the peak performance is not, as is generally believed, obtained when the calcium content is at a maximum, but rather when the degree of calcium exchange is in the range of 60 to 89 equivalent percent and only when the framework Si/Al.sub.2 ratio of the zeolite is within the range of 2.0 to 2.4.
