Abstract

1,271,860. Making filter elements. APPARELLS MODERNES DE FILTRATION ET DE GRAISSAGE ET LES INDUSTRIES PLASTIQUES REUNIES. 28 Aug., 1969 [7 Nov., 1968], No. 42872/69. Heading B1D. [Also in Division B5] A filtration element comprises a filtration membrane with a plastics bead around its edge. The membrane and bead are preferably circular and have a further concentric ring within and joined to the bead by radial ribs (Fig. 5 not shown). Alternatively, the peripheral bead may have a series of holes or cavities therethrough (Fig. 3, not shown).
