Abstract

239,777. Fouard, E. H. Oct. 9, 1924, [Convention date]. Filters having sheet filtering-materials; filtering-media.-In an ultra-filtering device, the membrane e has embedded in it a trellis or net d, of material, such as tulle, and is carried by a rigid support a having perforations b. A layer c of filterig material, such as silk, may be interposed between the membrane and support. The membrane is preferably formed by applying successive coats of collodion solution to the layer c over which the net d has been wound. Specification 212,233 is referred to.
