  • Method and an apparatus for controlling a flow of pulp suspension
    Patent number: 8177937
    Abstract: Apparatus and methods for controlling the flow of a pulp suspension from a container in which the pulp is processed or stored are disclosed. The container is pressurized to a first pressure and includes an outlet for the pulp suspension, a pump includes an inlet and an outlet, and the pump inlet is connected to the container. The pulp suspension is fed from the inlet to the outlet of the pump and provides a controlled decrease in pressure to which the pulp suspension is subjected in the pump during such transport, and the flow from the container is controlled by adjusting this controlled decrease in pressure.

  • Mixing device
    Patent number: 7033069
    Abstract: Apparatus for mixing a fluid with a flowing material is disclosed including a chamber having an inlet for connection to a circular inlet conduit and an outlet for connection to a circular outlet conduit, and a supply conduit for supplying the fluid to the chamber, the inlet having a cross-section which is substantially circular at one end and which continuously transforms to a substantially elongated cross-section at the other end, and the outlet has a cross-section which is substantially circular at one end and which continuously transforms to a substantially elongated cross-section at the other end, and the supply conduit is located between the inlet and the outlet.
