A process and apparatus for filtering substances by introducing a filter band across a passageway through which the substance flows, the filter being passed through inlet and outlet ports sealed to prevent leakage therefrom for example by thermal solidification therein of the substance being filtered or any other suitable sealing substance to form sealing plugs in the ports, and the filter being advanced to locate a fresh part thereof across the passage by supporting the filter upon a reciprocable backing support, moving the backing support in a directio...


A process for filtering a substance flowing through a passage comprising introducing a filter by passing it through inlet and outlet ports flanking said passage so that a part of the filter extends across said passage, sealing said ports against substantial leakage therethrough of said substance, supporting at least said filter part extending across said passage by means of a filter backing support permeable to flow therethrough of substance filtered by said filter, said filter backing support being reciprocable in the direction of extension of said filt...
