Abstract

563,768. Filters. VOKES, C. G. Feb. 8, 1943, No. 2108. [Class 46] [Also in Group XXVIII] A filter element A is produced by transversely folding a strip of material along lines forming reversely directed triangles 2, 3 separated by portions 4 of rectangular or tapered outline. On folding, pockets closed on three sides are produced with adjacent pockets having their apices at opposite ends of the filter where they are clipped into the grid-bars of a frame. Reinforcement B may be inserted on one or both sides.
