摘要:
A dynamic filter system includes a dynamic filter assembly including one or more filter elements and one or more members disposed within a housing. The filter elements and the members are interleaved and arranged to rotate with respect to one another. The dynamic filter assembly preferably includes one or more mechanisms to prevent preferential fouling.

A bed including a frame, an articulating deck on the frame having head, seat, and foot deck sections, and a mattress on the deck. The deck foot section and mattress foot portion have a first length when the foot section is in the up position and a second length shorter than said first length when the foot section is in the down position. A first driver varies the length of the deck foot section, and a second driver moves the foot section relative to said seat section between the generally horizontal up position and the generally vertically downwardly extending down position.
摘要:
A submicron filter assembly (24) is added to an exhaust gas controlled destruction and oxidation unit (10). Controlled destruction and oxidation unit (10) treats exhaust gas from at least one semiconductor wafer fabricating reactor. The submicron filter (24) filters submicron particles out of the treated exhaust gas to prevent visible plumes from forming in wafer fab exhaust systems (stacks). The controlled destruction and oxidation unit (10) and submicron filter assembly (24) are ideally suited for use at the point of generation of the exhaust gases. In one embodiment of the invention, the submicron filter assembly comprises an electrostatic filter (26). The electrostatic filter (26) includes a positively charged first grid (28) and a grounded second grid (30). The second grid may include a mist screen for removing particulate build-up. In another embodiment of the invention, the submicron filter assembly (36) comprises a mist eliminator (38) and a HEPA filter (40).
