Abstract: Methods and apparatus are disclosed for uniformly distributing a flowing medium flowing in a first direction in a conduit onto a surface so as to form a uniformly distributed medium thereon having a width greater than that of the conduit, the method including deflecting the flow of the flowing medium and simultaneously spreading the flowing medium from the width of the conduit to the greater width in a direction transverse to the first direction, and again deflecting the flowing medium in a passage having a generally curvilinear shape transverse to the surface in order to provide a substantially uniformly distributed and parallel flow of the flowing medium onto the surface. The disclosed apparatus includes a distribution housing including an inlet for the conduit and an outlet for the surface so as to form a uniformly distributed medium thereon, the distribution housing including a first distribution chamber substantially transverse to the conduit and diverging from the inlet to a substantially curved surface, a second distribution chamber extending from the substantially curved surface in a direction opposite that of the first distribution chamber, and a passage associated with the substantially curved surface for deflecting the flowing medium between the first distribution chamber and the second distribution chamber so as to provide a substantially uniformly distributed parallel flow of the flowing medium onto the surface.

Abstract: A process for separating a fibre suspension wherein undesired impurities, such as printing ink and other contaminating substances, are separated from the fibres in a flotation tank and the fibre suspension in admixture with gas is introduced into the tank via directed jets having a high inlet velocity. The tank has inlet openings for the mixture of suspension advantageously located at or close to the bottom of the tank and the jets of suspension are directed upwards, towards the free surface of the suspension in the flotation tank.

Abstract: A method and a device for achieving uniform transverse distribution and spreading of a flowing medium, such as liquids, gases, foam or mixtures of different types of material. The device comprises a distribution housing (1) with a wide outlet opening (2) and line (3) for the medium feed. In a distribution chamber (5) the medium flow is deflected while being spread in lateral direction to a transversely curved passage (8) where the medium flow again is deflected to an outlet chamber (6). In this outlet chamber (6), which extends to the outlet opening (2), an outgoing substantially uniformly distributed and parallel flow is obtained.
