    摘要: A certain group of electrically conductive refractory materials presently known for use in high temperature applications as throat constructions, melter sidewalls, forehearth, stacks, port sills, hot face lining for slagging coal gasifiers, slag runners, and linings for nuclear waste encapsulation furnaces may be used as electrodes permitting joule heating at temperatures in excess of 1200 C. in excess of about 4400 hours even in the presence of transition group element(s). More specifically, the invention is an electrode for melting earthen materials, wherein the electrode is made from an electrically conductive refractory material, specifically at least one metal oxide wherein the metal is selected from the group consisting of chrome, ruthenium, rhodium, tin and combinations thereof.

    摘要: The present invention is a method and apparatus for in-can waste reduction. The method is mixing waste with combustible material prior to placing the waste into a waste reduction vessel. The combustible portion is ignited, thereby reducing combustible material to ash and non-combustible material to a slag. Further combustion or heating may be used to sinter or melt the ash. The apparatus is a waste reduction vessel having receiving canister connection means on a first end, and a waste/combustible mixture inlet on a second end. An oxygen supply is provided to support combustion of the combustible mixture.

    摘要: Bioprocessing apparatus and method using centrifugal acceleration of cells to maintain a culture within a reaction zone. The reactor has an inflow at a relatively distance inlet and an outflow at an inwardly spaced point toward the rotational axis. The reaction chamber has an inwardly diverging zone with a velocity gradient which captures cells of varying sizes. A recycle system is preferably used to recycle medium containing nutrients for the culture microbes. Byproducts of the cells are removed by the circulated medium and can be extracted using a desired extraction process.
