Abstract: The invention relates to a device for discharge limitation and simultaneous temporary storage of waste water and also separation of settleable and floating matter from foul water and is notable for the fact that it comprises a cyclone chamber (2) which is connected to an inlet (1), which is constructed in accordance with the natural spiral shape of the vortex and which comprises round openings (4; 6) at the top and bottom, and in that a rotationally symmetrical container (8) seamlessly adjoins the top opening (6), in which container (8) a guide pipe is disposed which extends centrally from the top opening (6) to just below the upper edge (10) of the container.
Abstract: A cyclone and process for fluidized catalytic cracking of heavy oils is disclosed. Gas and entrained solids are added tangentially around a vapor outlet tube in a cylindrical tube cyclone body. Solids and some gas is withdrawn via a plurality of openings radially and longitudinally distributed in the cylindrical sidewall of the cyclone body. Distributed withdrawal replaces or reduces conventional underflow of solids from an end of cyclone outlet and reduces solids reentrainment. 0-5 micron particle removal is enhanced by reducing eddy formation and particle bouncing near the cyclone sidewall. The device may be used as an FCC regenerator third stage separator.

Abstract: A method and apparatus for separating from a base liquid, particles contained therein by introducing the base liquid between facing rotating surfaces which are imparted mutually different speeds of rotation relatively to the environment. The method is carried out in a container holding the liquid, wherein the two facing surfaces are rotationally symmetrical about an axis and preferably are in contact with the liquid in their entirety, and wherein the surfaces are used for radial boundary-layer transportation of the particles to be separated.
Abstract: The Induced Long Vortex Cyclone separation method and apparatus allows a three fold increase in residence time and therefore enhances the separation efficiency. The flow rate capacity is increased about 1.7 times for the same pressure drop and energy consumption compared to a conventional cyclone. The ILV cyclone could be used in addition for centrifugal separation of gases having a large difference between their molecular weights.

Abstract: A method for on-the-fly detection and separation of multiple checks or like documents transported in a track, wherein the documents are first subjected to twin opposed vacuum forces from a suction source, to separate multiple documents; then a measuring and analysis of the resulting pressure differentials is taken within the vacuum-forming system; the system being provided with a cyclonic filter-separator upstream of the suction source, for removing and storing dust and debris entrained within the vacuum-forming air flow; the cyclonic filter-separator being designed to provide constant vacuum-forming airflow regardless of the nature or quantity of debris removed and collected; the system also being provided with a pressure sensor to give clear indication of the separated/unseparated state of the passing documents, and to exhibit a variable damping accessory.

Abstract: A separation vessel (10) for separating materials of different densities comprising a chamber (14) having an external periphery (20A) at least part thereof which progressively increases from one section to another section. A mixture of materials of different densities enters the chamber (14) through an inlet (13) and travels in a spiralling vortex progressively outwardly to the widest section of the chamber (14). A primary exit (17) for material of greater density is provided closely adjacent to the widest section. A secondary exit (16) for material of lesser density is also provided.
Abstract: An improved vortex reactor system for affecting fast pyrolysis of biomass and Refuse Derived Fuel (RDF) feed materials comprising: a vortex reactor having its axis vertically disposed in relation to a jet of a horizontally disposed steam ejector that impels feed materials from a feeder and solids from a recycle loop along with a motive gas into a top part of said reactor.
