Abstract

334,569. Pickard, J. A., and Rogers, F. May 7, 1929. Filters comprising grids or gratings; filters with loose filtering-materials. - The elements of an edge filter are formed as discs 1 with central apertures 3 and isolated spacing protuberances 2 pressed-up on both faces of the element The protuberances are preferably arranged as a circular group, those on one face alternating with those on the other. Elements as described are preferably arranged to alternate with plain discs 5, as shown in Fig. 2. The elements may be tapered outwards, so that wedge-shaped spaces are formed in which a filter aid is effectively retained. Fig. 3 shows an arrangement in which saucer-shaped elements are used, and Fig. 4 one with conical elements.
