Abstract: An apparatus for treating a fibre suspension in a liquid to remove therefrom solid foreign particles. The apparatus has an inlet for receiving inflowing fibre suspension mixed with solid foreign particles; a first outlet for discharging part of the suspension liquid and said solid foreign particles; a screen positioned to define a filtering enclosure extending between said inlet and first outlet; a rotor disposed within said filtering enclosure for rotation therein to apply to the suspension fluidizing forces breaking up interlocked fibre flocs present therein and thereby fluidizing a part of said suspension to exit therefrom through said screen; and a second outlet communicating with the exterior of said screen to allow exit of fluidized suspension. The rotor has a plurality of radially extending blades supported by a central shaft, and the screen has a plurality of radially extending ribs inwardly directed to a predetermined clearance with said radially extending blades to thereby establish fluidizing forces acting upon the suspension.

Abstract: PCT No. PCT/DE79/00090 Sec. 371 Date Apr. 21, 1980 Sec. 102(e) Date Apr. 21, 1980 PCT Filed Aug. 18, 1979 PCT Pub. No. WO80/00423 PCT Pub. Date Mar. 20, 1980. A pulp suspension of waste paper which is laden with air bubbles is introduced into a flotation cell. Fine air bubbles rise through the pulp suspension toward the top. Printing ink and other impurities are deposited on the bubbles which form a foam layer on the surface of the pulp suspension. The foam which is laden with impurities is drawn off from the surface. The fibers which have been subjected to preliminary purification in this manner sink downwardly. For reducing the number of cells connected in series to fewer than a third, while obtaining the same degree of whiteness, the fibers which were subjected to preliminary purification are drawn off and are once again supplied to the flotation cell in the form of an air-laden pulp suspension. Alternatively, instead of the air-laden pulp suspension, a water-air suspension can be injected. The air bubbles which are thus introduced once again rise toward the top and traverse the sinking fibers in a counterflow. As a result, an intensive air-pulp contact is created.

Abstract: In a method for obtaining a uniform total pressure distribution in the compressor inlet plane of the inlet duct (1) of air-intake engines the incoming air in the region of the boundary layer is removed from the inlet duct (1) by way of openings in the walls (9, 10) bounding the inlet duct. In order to avoid the particularly disturbing influence of the corner boundary layer (19), in the region of at least one of the intersection edges (13) of the walls (9, 10) of the inlet duct (1) the air is removed in accordance with the thickness of the boundary layer (corner boundary layer 19) to be expected there.

Abstract: A current-limiting electric switch for low-voltage has a contact device with a contact finger and an elongated fixed contact arranged side by side. The contact finger is rotatably arranged and forms at one end a break together with the fixed contact and is at the other end provided with a flexible current connection conductor. The contact finger has its bearing point located between the two ends of a movable arm. Through the influence of electrodynamic forces from short-circuit currents, the contact finger is first rotated in one direction of rotation while maintaining the galvanic contact at the break, whereby the movable arm is displaced so that the distance between the bearing point of the contact finger and the fixed contact is increased. A stop means limits the movement of the contact finger in the first direction of rotation and brings about a continuation of the rotational movement in the opposite direction of rotation resulting in an instantaneous contact opening.

Abstract: A method for debarking treetrunks by means of an annular debarking apparatus is proposed, in which, in a known manner, the pressing force of the peeling tools against the trunk can be arbitrarily changed in operation and, with running rotor, the peeling tools can also be shifted into an open position out of contact with the trunk. The method is characterised in that the controlling of the pressing force and the opening of the tools are effected solely via the arbitrarily changeable rotational speed of the rotor, using the movement-effective mass of the peeling tools, which counteracts an elastic force stressing the peeling tools, in a known manner, permanently into the closed position. The elastic force here remains unchanged from outside during the operation of the annular debarking apparatus. The particular advantage of the method according to the invention consists in that it can be carried out with a high degree of operational reliability and considerably less constructional expense on the part of the annular debarking apparatus compared with the known methods which allow arbitrary control of the pressing force of the peeling tools and shifting thereof into an open position with running rotor. Furthermore, an annular debarking apparatus for carrying out the method according to the invention is proposed, which is characterised in that the rotor drive 5,6,7 for driving the rotor 4 is designed with arbitrarily changeable rotational speed.
