    Abstract: A filter tube for use in earth coated type filters includes a flexible permeable tubular sheet internally supported by a helical spring which in one embodiment extends partially along the length of the filter tube. The unsupported free end or an intermediate portion is subjected to oscillation to dislodge contaminated coating material accumulated on the surfaces of the filter sheet. External means are provided at the free end of the filter to permit oscillation and to support a plurality of filter ends. In another embodiment, an internal spring is connected between opposite ends of the filter tube to support the full length of the tube wall. One end of the tube is connected to an external spring and anchor plate. In a slack position, the tube end folds over an end collar connected to the spring. Extension of the anchor plate applies tension to stretch the spring and tube to a taut position during a cycling operation which oscillates the tube to dislodge accumulated material.

    Abstract: A filter device is disclosed, comprising two compartments within a housing. The first compartment includes a filter element, of the screen or the disc types, with communication to the filtered fluid outlet of the housing. A controllable valve communicates the first compartment with the inlet of the housing across the second compartment. A drain valve connects the first compartment with outside the housing. For flushing the filter element by reverse-flow, the first valve is closed and the flushing fluid drains through the drain valve. In a further embodiment two or more filter elements and associated compartments and valves are installed, in parallel, within the same housing, so that by stopping the filtering operation of one of the filter elements, it becomes flushed with the product, filtered fluid of the other element. The filter elements are preferably of the disc-type, and provided with a hydraulic piston and cylinder assembly for compacting and releasing the discs during the filtering and flushing modes of operation, respectively, to effect a more thorough rinsing of the discs. In addition, the displacement of the discs compacting cylinder can be controlled from outside the system.
