Abstract
A screen for filtering undesirable particles from a liquid has a flat parallel array of warp filaments spaced apart less than a preselected minimal linear dimension of the undesirable particles transverse to a parallel array of pairs of shute filaments, the shute filaments of each pair being oppositely woven about the warp filaments to secure the warp filaments and maintain the spaces therebetween, the spaces between pairs of shute filaments being greater than the preselected minimal linear dimension of the undesirable particles so that the screen is characterized by rectangular flow apertures therethrough, the apertures being an access ratio ranging as great as 4 to 10, even for filaments having diameter ranging as small as 0.007 to 0.001 inches.
