Abstract: Phases of different densities are separated from each other in a vortex separator chamber. A primary flow to be cleaned drives a secondary vortex flow in the chamber. The primary flow is introduced into the chamber centrally between the chamber ends through at least one flow inlet channel or bed having an axial length shorter than an axial chamber length and a radial inlet depth such that the primary flow is adapted to the secondary vortex flow. For this purpose the primary flow is fanned-out so that it smoothly merges into the secondary vortex flow close to the inner surface of the chamber wall to avoid turbulent flows and thus losses of the primary flow energy are reduced. Cleaned gas is sucked out through immersion pipes reaching centrally into the chamber from opposite ends. Heavier particles are removed by centrifugal force and discharged through gaps in the end walls of the chamber and/or through at least one peeling slot in the axial cylindrical or spirally shaped chamber wall.

Abstract: The invention relates to a vortex chamber separator (1) with at least one vortex chamber and at least one immersion pipe (11, 12). Each immersion pipe is arranged coaxially in the vortex chamber and is connected to a pure gas outlet. In the region of the end walls (9, 10) of the vortex chamber there is an angular channel (13) surrounding at least one immersion pipe (11, 12), forming an annular vortex casing (14). Via a peripheral slot (15), the latter is in communication with the vortex annular space (16) surrounding at least one immersion pipe (11, 12). There is a spiral immersion pipe casing in the region of the immersion pipe opening (17) which is connected to the annular vortex space (16) and at least one fume outlet.

Abstract: A wing type sailing yacht is constructed to incorporate the airfoil principle. Such a yacht has a boat hull, a mast, and a sail, including a bow with a bow keel and a stern with a stern keel. Each keel has a buoyancy control fin (9, 10) at its lower end. An outrigger arm (6, 6') is attached laterally to each side of the hull. The end of each outrigger arm carries a downwardly projecting fin strut which in turn carries a further buoyancy control fin (8, 8'). The buoyancy control fins (9, 10, 8, 8') form a four-point wing or airfoil type system for producing lift or buoyancy and for maneuverability and stability. The outrigger arms (6, 6') are built as narrow surface wing type carriers having a negative sweepback. The arms have a predetermined elasticity. A pontoon (12, 12') is attached to the end of each outrigger arm. The fin struts act as lateral control fins or steering wings (11, 11').

Abstract: A sailing yacht having a hull and a sectional mast holding a sail, is equipped with a canard rudder and two rolling keels. Each rolling keel has a ballast container. A three point wing system is formed by wings carried by the canard rudder and by the two rolling keels for producing buoyancy, for steering, and for stabilizing. Thus, the three point wing system has a fore wing (9) forming an end wing of the canard rudder and two aft wings (11, 11') forming end wings of the rolling keels (10, 10'). The rolling keels (10, 10') are tiltable about rotational axes extending above the water line approximately in parallel to the hull axis, whereby the rolling keels (10, 10') are normally above the water line and only the long end (14, 14') of the wing (11, 11') dips into the water, so that the end disk wing (15) functions as a lift producing surface. The ballast is shiftable between two ballast containers 17, 17'.

Abstract: The invention concerns a process for separating and/or precipitating of solid and/or liquid particles (disperse phase) from gaseous and/or liquid media (continuous phase) as well as for separating mixed gases (gas-gas-separation) and/or mixed fluids (fluid-fluid-separation) as well as for screening and/or classifying by means of a vortex chamber separator with suction tube 35. For decrease of flow resistance at generation of moment of momentum the contact zone between main flow and eddy is adjusted to cylinder casing that the tangential initial impulse in laminary bottom flow is increased by means of decrease of laminary bottom flow impulse, secondarily circulating in vortex chamber. For reduction of loss of impulse by means of dissipative drop of pressure in flow of main channel, laminary bottom flow is dynamically balanced with constant or mainly constant average main flow rate.

Abstract: Solid particles suspended in a flowing gas are separated from the gas by gentially driving the gas and particles into a substantially cylindrical eddy chamber substantially along the entire axial length of the chamber. Axially arranged suction pipes are connected to suction fans and reach mirror-symmetrically into the eddy chamber for withdrawing the clean gas from a central zone of the chamber. The eddy chamber has end walls through which the suction pipes extend concentrically relative to the longitudinal axis of the cylindrical eddy chamber. Particle exits are provided in the chamber end walls at points to which secondary flows tend to transport the particles. These particle exits are so located that they are in line with the transport direction of the particles by the secondary flows.

Abstract: A method and apparatus are disclosed for separating components from a flog medium by means of centrifugal force. The flowing medium travels through two stages. In the first stage a spin is generated and in the second stage the actual material separation is accomplished in one or several separating devices by means of one or several whirling or eddy sources. The apparatus includes a spin generator housing and separator chambers, whereby spin conduits extend into the separator chambers toward exhaust pipes to such an extent that a spacing is provided between the spin conduit and the exhaust pipe. At least one exhaust suction is tangentially effective in the area of this spacing.

Abstract: Solid components such as dust particles having a lighter density are sepaed from a flowing medium, such as a gas, wherein the dust is suspended. The gas has the lightest density. For this purpose, the flowing medium which includes the gas and the solid components suspended therein, is detoured in a bent channel and partially introduced into a whirling chamber, which contacts the bent channel along its entire axial height to communicate with the channel along its inner bent portion, whereby the flow produces a centrifugal field in said whirling chamber. Two immersion pipes extend coaxially into the chamber, one pipe from each end. The pipes are connected to suction means, such as fans, for sucking the lighter component out of the whirling chamber. These pipes extend deep enough into the central region of the chamber so that the sucking of the lighter component out of the chamber takes place at said central region of the whirling chamber.

Abstract: The present apparatus is constructed to convert or reconvert spin flow energy into pressure energy. For this purpose a conduit forms a chamber intermediate the ends of the conduit. The chamber and a flow control member operatively supported in the chamber are of rotational symmetry and so shaped that predetermined flow passage configurations are accomplished which facilitate the conversion of the spin flow into an axial flow.

Abstract: A gaseous or liquid fluid to be centrifuged, for the purpose of purification or of separation of different phases, is conducted at high speed in a curved channel past a vortex chamber formed in one of the channel walls at the concave side thereof, this chamber being partly separated from the main fluid path by an overhanging sharp upstream edge and by a possibly rounded downstream edge which extend over the full width of the channel. A body of fluid whirling in this chamber develops a cylindrical core free from entrained solids, or from an accompanying heavier phase, which can be axially extracted from the chamber while the remaining fluid continues its flow through a reduced channel portion which may also be curved and provided with another vortex chamber to repeat the process. Entrained particles may be removed from the solid-enriched residual flow by way of end apertures along the periphery of the vortex chamber and/or at the convex side of the curved channel.

Abstract: The fluid to be treated is directed along a main flow path and past a flow-off edge on the concave side of the main flow path to produce a stationary whirl at least contacting the main fluid flow and in which suspended matter is separated from the fluid, by centrifugal force, to provide purified fluid. At selected locations in the stationary whirl, a selected one of the purified fluid and the suspended matter is separated and withdrawn from the stationary whirl. The non-separated portion of the fluid volume, whose suspended matter content is now changed, is returned into the main flow. The geometric form of the whirl axis is selected in accordance with the particular requirements of each installation. Thus, starting from a simple cylindrical configuration, the whirl may take any form having a curvilinear axis, even an annular form with a circular axis.
