Wing type sailing yacht

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').

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.

Method and apparatus for separating particles from a flow by centrifugal

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.

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.

Apparatus and method for separating a specific lighter component from a

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.
