A filter-press plate, constructed in any kind of material appropriate for the case, and essentially characterized by the circumstance of being determined by a circular surface, which presents on one of its sides a series of concentric projections, which are divided into eight equal sections, according to four diameters or two to two perpendicular axes, which divide the assembly into said eight sections, and determining such divisions some grooves or channels that starting from the periphery of the plate, go to the center thereof. It is also characteristic that the opposite face of this plate forms a smooth surface, albeit with a projection around its perimeter. (Machine-translation by Google Translate, not legally binding)
