Abstract: A pressure-filter apparatus includes at least one filtration chamber coupled with a source of slurry. The filtration chamber is also coupled with a source of fluid at an elevated pressure, which may be arranged in series or in parallel with a source of wash fluid. The pressure-filter apparatus may also include a source of fluid at a conventional pressure.

Abstract: A pressure filter includes two continuous mating surfaces movable relative each other and a filter medium capable of being disposed therebetween. A surface, provided for supporting the filter medium, is bounded by and is substantially coplanar with one of the continuous mating surfaces. The filter further includes a shallow inlet cavity, bounded by the other of the continuous mating surfaces, and an inlet distributor in communication with the inlet cavity. The inlet distributor includes at least one opening and may be of internal or external type. When the mating surfaces are pressed together, a shallow filtration chamber is defined by the inlet cavity and the filter medium. The filter apparatus may include a plurality of shallow filtration chambers, stacked one above the other, and constructed as described above.

Abstract: An adhesive bandage includes a carrier strip having at least one adhesive portion and a dressing element disposed adjacent to the adhesive portion(s) along the entire length of the carrier strip. The width of the carrier strip is greater than the width of the dressing element.
