Abstract: On décrit un système permettant de laver et de déshydrater une suspension de pâte à papier, ce système comprenant deux éléments de tamis (1) creux et de forme circulaire-cylindrique qui comportent eux-mêmes des chambres d'évacuation disposées à l'intérieur desdits éléments de tamis pour évacuer le liquide. Les éléments de tamis tournent chacun en sens inverse pour former un espacement (2), au moins un de ces éléments de tamis (1) étant situé dans un creux (7, 8) qui entoure partiellement l'enveloppe (3) de l'élément de tamis et qui, dans le sens de rotation de l'élément de tamis, converge en direction de l'enveloppe de l'élément de tamis. Cette invention concerne un système d'étanchéité (5) destiné à une bâche d'alimentation en pâte à papier qui distribue la pâte à papier sur la surface de l'enveloppe des éléments de tamis. Le fait de former un espace B-A qui se réduit progressivement au niveau de la bâche d'alimentation (4) en pâte à papier dans un sens inverse à la rotation de l'élément de tamis permet de réaliser un joint auto-étanche simple formé de la suspension de pâte à papier qui assure le renvoi des résidus de fibres dans la zone de déshydratation. Avec la présente invention il n'existe pas d'usure entre les éléments de tamis et le joint d'étanchéité.

Abstract: A protective body heat retaining pod that is carried in a folded condition within a special purpose backpack attached at the rear of a harness that is worn over a conventional lifejacket by both civilian and military personnel who find themselves in or about to enter a cold water environment while awaiting rescue from an emergency situation. A hood to be pulled over the head and cinched tightly around the face of the wearer is attached to the back of the protective body heat retaining pod. The protective pod has a sealed body portion that fits around the legs, arms and torso of the wearer within which a small volume of water is trapped and heated by the wearer's body heat to slow a drop in the wearer's body temperature. A cinching cord is attached to the bottom and sides of the protective pod to be pulled upwardly by the wearer, whereby the protective pod is correspondingly pulled upwardly and inwardly to draw and hold the wearer's legs in a fetal position so as to reduce the size of the body portion and thereby minimize the volume of water to be trapped and heated therewithin.
