    摘要: A harvesting device for zooplankton (1) or other micro organisms in a body of water (2). The new and inventive in the harvesting method is amongst others a bubble diffuser (3) arranged for being submerged in the body of water (2) and arranged for releasing gas bubbles (4) preferably air, in the body of water so as for said bubbles (4) may attach to zooplankton (1) and bring them closer to the surface (21) of said body of water (2) for collection by means of a skimmer or trawl (5). Said trawl is further arranged as a skimmer with a transportation tube from the aft of said skimmer to a vessel which both tows the trawl and processes the harvested zooplankton at the same time.

    摘要: Air governing means at a refuse burning furnace may include a sleeve, which is axially reciprocable with respect to an air passage port in the furnace wall; in order to produce a high air velocity, the air is forced through a narrow, annular clearance between the perimeter of the inward end of the sleeve, and the passage port, the outward end of the sleeve being normally closed; to accommodate for axial mis-alignment at the outward end, the sleeve is adapted to cooperate with a tubular member projecting from the back wall of a plenum chamber supplying the passage port with air; the tubular member is provided with a head displaceable in a plane perpendicular to the longitudinal axis of the tubular member, and further having a tapering front end to facilitate re-introduction into the sleeve, when the latter, in order to perform a scraping function, has performed a stroke exceeding normal governing movement.
