    摘要： A method includes forming an aqueous fibre suspension including cellulosic fibres from one or more raw material flows, and applying at least one chemical and/or physical control measure to the aqueous fibre suspension or at least one of its raw material flows for control of microbial activity in the aqueous fibre suspension or the raw material flow before an inlet of an intermediate residence entity. In this manner a starting ORP value for the aqueous fibre suspension is obtained. The aqueous fibre suspension is in the intermediate residence entity at least a minimum delay time. A final ORP value is measured for the aqueous fibre suspension after an outlet of the intermediate residence entity before the formation of the fibrous web. An ORP difference value between the starting ORP and final ORP values is calculated. Finally, the aqueous fibre suspension is formed into a fibrous web and dried.

    摘要： Pulp is effectively and simply fed into a pulp tower using at least one feed pipe having a number of openings that are spaced different distances from the bottom of the pulp tower. The opening through which the pulp being fed into the tower flows automatically changes depending on the level of the existing pulp in the tower. The feed pipe may have a wide variety of different configurations with openings formed or shaped in different manners, and baffles or similar guides can be used to uniformly spread the pulp being fed through the feed pipe onto the top surface of the existing pulp without mixing. This configuration allows the amount of pulp pumping energy to be minimized while still effectively feeding pulp into a tower.

    摘要： A vane shaft is suspended within a container in a pendulum or swinging fashion at its drive shaft by means of a pivotable coupling. The drive shaft can constitute the output shaft of a drive arrangement composed of a drive motor equipped with a transmission or gearing unit and supported upon a radial arm member. The drive motor together with its transmission also can be arranged in or at a central axis of the orbiting or revolving path of movement of the vane shaft, and the drive shaft can connect the drive motor equipped with the transmission with the vane shaft in the manner of a Cardan shaft. The vane shaft also can be directly suspended at the vertical output shaft of the transmission or gearing arrangement by means of a pivotable coupling. At the lower end of the vane shaft there is secured a buoyant or float body member serving for the lateral deflection of the vane shaft. Above the level of the liquid confined within the container the latter is provided with a substantially ring-shaped guide arrangement which limits the deflection of the vane shaft towards the outside.
