摘要： The invention relates to a valve system for a space (1) which is under vacuum in relation to its surroundings (3), which valve system comprises a valve unit (7) which is intended to be arranged in association with a wall (2) which delimits the said space and has a wall opening (4) through the said wall, which valve unit comprises a valve (8) which is normally shut and closes the said wall opening but is arranged to be opened and allow air from the surroundings into the said space if the vacuum, i.e. the difference between the surrounding pressure and the pressure in the space, should exceed a previously defined value, which valve comprises a valve housing (12) which can be connected to the said wall (2) in association with the wall opening and which has at least one inlet opening (17) for air, a passage (6) for the air between the said, at least one, inlet opening and the said space (1), a valve seat (15) and a valve body (13) with a sealing surface (21) which is normally pressed against the valve seat by an external force with counteraction by the vacuum in order to keep the passage closed when the vacuum does not exceed the defined value but to permit the passage to be opened by the force developed by the vacuum on the valve body overcoming the external force when the vacuum exceeds the said value. According to the invention, the external force is obtained from a pneumatic power source (34).

摘要： Provided is a method for reducing resin content in sulfite pulp, in an ozone bleaching process where the sulfite pulp is bleached using ozone, at a pulp concentration of about 6 to about 14% by weight, and at a pH of less than about 7. The process includes the steps of alkalizing the sulfite pulp to a pH of greater than about 7 after ozone bleaching and then mechanically processing the sulfite pulp to press resin out of the sulfite pulp.

摘要： The invention relates to a method and a device for feeding out fiber pulp over an overflow rim (2) at the upper end of a cylindrical container (1), through which the pulp, which is suspended in liquid, is being fed continuously from the bottom and upwards. The distinguishing features are that the pulp is diluted at a level below the upper surface of the pulp by means of a multiplicity of diluting nozzles (15A-D), which extend downwards in the pulp and which are rotated around the vertical center line (12) of the container, and that the pulp, which has been fed upwards through the container, and the diluting liquid are mixed with each other to form an essentially homogeneous suspension with the aid of rotating scraper elements (14A-D) which extend downwards in the surface layer of the suspension and, at the same time as they are homogenizing the mixture, feed the suspension outwards towards, and finally over, the overflow rim.
