Abstract: A horizontal, Fourdrinier foraminous belt type, countercurrent, high-capacity, cellulose pulp washer is described. The described washer is equipped with a hood positioned over a portion of the belt and over vacuum boxes or receptacles under the upper loop of the belt. The gases and vapors drawn into the vacuum boxes or receptacles with the wash liquid are separated from the liquid in the receptacles and recycled to the hood to control the atmosphere in the hood and maintain the desired pressure differential for operation of the washer.

Abstract: An arrangement which allows patients confined to their beds, to use a toilet without leaving their beds. A sectionalized mattress is positioned in sequential steps so as to place the patient directly over a toilet without discomfort to the patient. The mattress together with the patient is positiond in a manner which allows the patient to use the toilet while sitting in an upright customary manner. The section of the mattress over the toilet is removed while the patient's weight is not directed thereon. Hygienic cleansing procedures are provided in conjunction with the toilet, and the patient is returned to a reclined position after repositioning the mattress and replacement of the section of the mattress that was removed to enable the patient to use the toilet. Replacement of that section of the mattress is carried out also while the patient's weight is not directed thereon. The mattress is positioned through a similar sequence of steps to place the patient directly into a wheelchair.
