Abstract

579,562. Filters. COMPAGNIE POUR LA FABRICATION DES COMPTEURS ET MATERIEL D'USINES A GAZ. Dec. 17,1941, No. 16301. Convention date, Dec. 26, 1940. [Class 46] [Also in Group V] A filter is moulded of plastic material of cylin drical, conical or partly spherical form to resull in an outer and an inner group of rows of ribs, the groups being joined to gether and crossing eacl other. Fig. 1 shows par of a cylindrical filte formed by using an inner mould with longitudinal grooves and an outer mould, in two parts, with circular recesses. The ribs 6 instead of being circular may be helicoidal, in which case the outer mould is in one piece from which the filter can be unscrewed after manufacture. In a modification the longitudinal ribs are on the outside of the filter and the circular or helicoidal ribs on the inside
