Abstract: An apparatus and method for providing an impregnation/rinsing of a web with fluid is disclosed wherein the web is repeatedly gently squeezed and allowed to open. A perforated conveyor belt carries the web within a longitudinal tank in which a series of squeeze rollers and a series of singular or cooperating rollers are arranged with the cooperating rollers being disposed intermediate the squeeze rollers. The web is carried by the conveyor belt beneath the first squeeze roller where the web is gently squeezed in a nip defined between the conveyor belt and the roller. The conveyor belt then carries the web above a cooperating roller. After the web has been gently squeezed, it is allowed to absorb the fluid in the tank without restraint until the web is gently squeezed again between the conveyor belt and the next squeeze roller. The steps of squeezing and absorbing are repeated throughout the longitudinal tank.

Abstract: A unit for automatically cleaning items such as laundry or the like comprises a plurality of reciprocating plungers mounted to engage the items within a tank containing the items and a cleaning liquid. Each plunger comprises a piston mounted within a canister. The piston is mounted within the canister in an arrangement which permits a limited relative movement between the piston and canister, thus developing a bi-directional pumping action. With each stroke of the plunger, the piston forces liquid through the items to be cleaned, first in one direction and then the other, by virtue of the limited movement of the piston relative to the canister, the latter serving to assist in holding the items to be cleaned in a position for encountering the liquid being driven by the piston. The combined rotary reciprocating action of the plungers not only serves to clean the items in the tank but also to slowly propel them from the inlet to the outlet end of the tank so that a continuous cleaning process is performed.

Abstract: The present invention relates to an apparatus for continuously carrying out washing, raising milling, scouring, bleaching and dyeing, of fabric. In carrying out the aforesaid operations, it is essential for the fabric to be carried forward in a stabilized and relaxed state accurately and continuously in a treating fluid and on the other hand the treating fluid should move vigorously without a hitch and come into contact with the fabric uniformly. In the present invention the stabilized posture of the fabric particularly in a treating space is emphasized and at the entry of the treating space the fabric is folded in the wavy form in good order resulting in the more uniform contact between the treating fluid or liquor and the fabric. Further jet or blowing angles of jet nozzles have been arranged to make jets of the treating liquor accurately strike the fabric.

Abstract: Liquid-containing pulp material, especially sulphate pulp containing black liquor, is deposited as a mat on a moving filter and subjected to displacement washing with a liquid such as clean water supplied to one side of the pulp mat and displacing the black liquor, which emerges in substantially undiluted form from the opposite side of the mat. The filter is a screen moving over a supporting floor, said floor and screen together forming a "resistance floor" providing a substantial flow resistance to the liquid. A layer of displacement or washing liquid (e.g., water) is maintained over the pulp mat covering the surface thereof. This layer may have a depth or height of e.g. 10 to 100 cm, thus protecting the surface of the mat against the effect of supply means for displacement liquid and providing a pressure on the upper side of the pulp mat assisting in overcoming the flow resistance of the pulp and the floor.
