Title: Dewatering watery pulp to form paper, board or tissue
IPC: D21J1/00
Filed: 1965-11-12
Abstract: In a paper-making machine in which pulp is directed into the converging passage between an upper wire and a lower wire, there is a stationary pressing element on one of the wires to urge the wires together to form the converging passage, the shape of the element and the tension in the other wire being so chosen with respect to the pulp that a substantially constant pressure-i.e. the pressure in the pulp as it leaves the headbox-is maintained on the pulp as it flows through the passage.  The pressure may be increased on the pulp once the actual web has been formed.  The pressing element, which may act on the upper or lower wire, comprises a plurality of slats extending transversely of the web forming direction and obliquely to the wire. The slats are mounted in a suction box.  The slats may form a curved wire-engaging surface-suitable examples being given.  The headbox, element, and breast roll are all adjustable so that the pulp leaves the headbox adjacent the converging passage and in the axial direction thereof.

Title: Soap drying process
Inventor: WARD NORMAN ERNEST
IPC: C11D13/26
Filed: 1963-12-23
Abstract: In a process for partially drying liquid soap in a plate type heat exchange having unrestricted outlet, steam is injected into the liquid soap prior to its introduction into the heat exchanger. This reduces the pressure drop across the heat exchanger by reducing blocking of the heat exchanger caused by solidified soap. The amount of steam, which may be superheated, saturated or wet, is preferably just sufficient to heat the soap to its boiling point at the pressure obtaining at the inlet of the heat exchanger.  The liquid soap is suitably one containing 27-33 wt. per cent water, and may also contain free fatty acid, e.g. 2-12 wt. per cent.
