Abstract: The invention concerns a device for separating the constituents of a heterogeneous mixture and its uses. Said device comprises a separation chamber (100, 250, 350, 450, 650, 724, 850, 903, 1106) having a one of its ends an inlet and at the other an outlet comprising a first ring-shaped orifice (110, 210, 310, 410, 510, 610, 710, 810, 919) coaxial with said chamber, and a second ring-shaped orifice (111, 211, 311, 411, 511, 611, 711, 811, 920) coaxial with said first ring-shaped orifice and whereof the external diameter is smaller than said first ring-shaped orifice internal diameter. The invention is characterized in that said separation chamber has a cylindrical shape and said first orifice external diameter D1 is smaller than said chamber internal diameter D0. The invention also concerns a method using said device.

Abstract: Disclosed is an improved vacuum cleaning apparatus utilizing a self-sustained vortex flow in a centrifugal separator. More specifically, vortex flow is maintained via pressure differentials allowing the ejection of dust and other particles without bags, filters, or liquid baths. Furthermore, the impeller inside of the separator serves the dual purpose of moving air through the system as well as creating a cylindrical vortex fluid flow providing an efficient and simple configuration. Also disclosed herein is a complete toroidal vortex vacuum cleaner in which a toroidal vortex nozzle is used in conjunction with the centrifugal separator. The vacuum cleaner exhibits recirculating airflow that not only prevents unseparated dust from escaping into the atmosphere, but also conserves the kinetic energy of the flowing air. The present invention excels in producing clean air of a better quality more efficiently, more quietly, and more simply than the prior art.

Abstract: A centrifugal separator of vertical axis for the separation of a flowable medium, in particular a dental liquid/solids mixture, from conveying suction air has a motor-driven removal element (10) which is arranged in a flow chamber with a rotationally symmetrical peripheral wall (4) and a bottom limit. A top, central outlet (9) for the suction air and a bottom, peripheral outlet (8) for the flowable medium are flow-connected to an inlet (5) for the mixture to be separated, which opens out between these outlets, the peripheral outlet (8) being surrounded by an annular non-return valve (7). Vanes (16) are provided on the removal element (10) between the mixture inlet (5) and the peripheral outlet (8). The mixture inlet (5) is formed between the bottom edge of the peripheral wall (4) and a holding ring (22) for the non-return valve (7).

Abstract: A centrifugal separator for solids and fluids can have its vortex chamber and an outlet duct internally aligned as a hard material or wholly formed from a hard material which is preferably selected from the group which consists of sintered titanium carbide, titanium nitride, titanium boride, zirconium carbide, zirconium diboride, niobium carbide, tantalum carbide, chromium carbide, chromium boride, molybdenum silicide, and tungsten carbide with a nickel or cobalt binder, and cubic boron nitride, boron carbide, silicon carbide and corundum.

Abstract: A voraxial separator and analyzer apparatus includes a composite fluid passing tube having a tube upstream segment and a tube downstream segment; a rotation acceleration vane structure rotationally mounted within the tube upstream segment and being oriented to deliver angular acceleration to a composite fluid within the tube about the longitudinal axis of the tube for separating the fluid into radially stratified component layers within the tube in the order of component density and to propel the fluid toward and through the tube downstream segment; an acceleration vane drive mechanism drivably connected to the rotation acceleration vane structure; a rotation maintenance vane structure rotationally mounted within the tube downstream segment and being oriented to deliver angular acceleration to a composite fluid within the tube about the longitudinal axis of the tube for maintaining the rotational velocity of the fluid imparted by the rotation acceleration vane structure against friction losses; and a maintena

Abstract: An apparatus comprising a longitudinally extending housing having a fluid inlet port; a plurality of spaced apart members rotatably mounted in the housing to transmit motive force between fluid introduced through the fluid inlet port and the members and to separate the fluid into at least two fluid streams; and, a fluid outlet port positioned on the housing for receiving each fluid stream.
