Abstract
Apparatus for treating a pulp suspension with a treatment liquid is disclosed, comprising a continuous pervious belt for receiving the pulp suspension and moving it through a treatment zone in a predetermined direction. A treatment liquid supply is located above the continuous belt for supplying the treatment liquid onto the pulp suspension as it travels through the treatment zone, and a collector is located below the continuous belt for receiving liquid passing through the pulp suspension. The treatment liquid supply includes a treatment liquid feed pipe for supplying a flow of the treatment liquid, a distributor for dividing the flow of treatment liquid from the treatment liquid supply into first and second flow components, the first flow component being in the direction of the moving belt and the second flow component being counter to that direction, a deflector for deflecting the second flow component into that direction, and first and second plates for applying first and second flow components onto the pulp suspension, whereby the amount of the treatment liquid supplied to the pulp suspension is controlled.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
