    摘要: A method for manufacturing a gas mask canister using a HEPA filter media having plastic separating plates inserted into between HEPA filter media at certain intervals. The HEPA filter, impregnated activated carbon, and a pre-filter are accommodated within a cylinder. The cylinder is inserted into a canister having an upper portion and a lower portion detachably coupled together. The impregnated activated carbon, the plastic separating plates and the casing of the canister can be reused, and the rest of elements are burned. A vinyl coating sheet is peeled off from the canister after each use. An indexing tab for recording the number of times of peeling is attached on each of vinyl coated sheets, so that the number of uses can be known.

    摘要: A centrifugal extractor for extraction of an organic phase from a liquid mixture, such as liquid radioactive wastes, is disclosed. In the centrifugal extractor, both the separating weir and the divert disk are designed to be adjustable in their vertical positions. The extractor, thus, desirably separates the organic phase, including usable elements in addition to chemically toxic high radioactive elements, from the aqueous phase and desirably controls the reaction time of the two phases regardless of a variation of the mixing ratio and the rotational speed of the two phases. In the centrifugal extractor, a liquid suction and rotation unit sucks and rotates the liquid mixture and separates the organic phase from the aqueous phase while controlling the reaction time of the two phases. A height-adjustable separation weir unit is designed to locate the separating weir at a boundary layer between the two separated phases. A housing unit supports the suction and rotation unit and provides the path of two separated phases to the outside of the extractor.
