Abstract: PCT No. PCT/SE92/00557 Sec. 371 Date Feb. 28, 1994 Sec. 102(e) Date Feb. 28, 1994 PCT Filed Aug. 19, 1992 PCT Pub. No. WO93/04772 PCT Pub. Date Mar. 18, 1993.Methods for mixing a treatment agent with a pulp suspension are disclosed including supplying the pulp suspension to a mixing chamber, moving the pulp suspension through a mixing zone with the mixing chamber, supplying the treatment agent to the moving pulp suspension across the entire width of the mixing chamber prior to the mixing zone, and in which the height of the mixing zone is sufficiently small such that the pulp suspension and the treatment agent are subjected to kneading within the mixing zone in order to repeatedly stretch and compress fiber flocks in the pulp suspension. Apparatus for mixing the treatment agent with the pulp suspension are also disclosed.

Abstract: A pressure screen for separating a liquid mixture is disclosed, comprising a screen housing forming a cylindrical screen chamber, and an inlet housing directly connected to the screen housing and forming a cylindrical inlet chamber, the diameter of which is less than the diameter of the screen chamber. An inlet member is positioned on the inlet chamber for supplying a suspension to be separated substantially tangentially into the inlet chamber and an outlet member is positioned on the inlet chamber for discharging coarse contaminants from the inlet chamber, whereby the scrap particles are prevented from entering the screen chamber.

Date Jan. 6, 1994.Apparatus for mixing a processing medium with the pulp suspension within a bin is disclosed, the apparatus including a housing attached to a wall of the bin, a rotary shaft extending through the housing with a propeller attached to the shaft by means of a hub, and a nozzle surrounding the propeller for directing the pulp suspension from an inlet in the nozzle to the propeller. The housing includes a dilution chamber for the processing medium and an outlet from the dilution chamber for directing the processing medium towards the hub, and includes a gap separating the outlet aperture from the hub so that the processing medium can be contacted with the pulp suspension before the pulp suspension reaches the propeller.

Abstract: A device for sealing a rotary shaft (17), which is supported in bearings (18, 19) in an air-tight casing (20), which extends into a container (10), in which overpressure is maintained. The device comprises a seal holder (22) attached in the casing (20) with a mechanical shaft seal (21). The casing has openings (23) to render possible access to the side of the shaft seal (21) located in the casing (20). A detachable air-tight cover (24) is provided to close said openings (23) at operation.
