Abstract: An articulated liter is disclosed for assisting disabled patients in getting in and out of hydrotherapeutic pools. The litter moves progressively from a chair-like position for the patient to sit on, to a horizontal position in which the patient is supported in a supine position, to a position in which the litter is cantilevered over the pool and finally into a substantially vertical position in which the free end of the litter and the patient are submerged within the pool. The progressive movements of the litter are reversed to remove the patient from the pool.

Abstract: A continuous device and process for extracting liquid from mash, sludge or pulp bearing slurries. The device comprises a pair of parallel opposed and counter rotating rolls each consisting of a base roll member having circumferentially disposed grid member consisting of a multiplicity of upright standing leaves which interbolt to form a grid which encases the entire surface of the roll member. Raw material for deliquification is spread over the grid and compressed by an inflatable, reciprocating platen to express liquid through the grid into underlying collection channels. The rolls are then rotated toward each other to express additional liquid and produce a substantially dry material. The liquid collected in the collection channels is withdrawn by applying a negative pressure through orifices located at the axial extent of the rolls.
