    Abstract: A recyclable, flexible filter element comprising a tubular, outer braided jacket supported by a helical spring. The bottom of the tube of the jacket is turned inside the helical spring and is sealed by a removable fastening device which is inserted into the bottom of the helical spring to engage the spring through the thickness of the braided jacket. The top of the outer braided jacket is fastened and sealed to a flange and washer assembly which also contains the top of the internal support spring.

    Abstract: Filtering apparatus including a container having an inlet and an outlet and a filter interposed between the inlet and the outlet. The filter has a bottom plate fixed to the outlet and a top plate connected to a motor for gyrating the top plate. The two plates are connected by a helical spring and a filtering screen surrounding the spring.

    Abstract: The breaking up of filter aid cake (98), Fig. 5, (not shown) deposited by liquid flow on to vertical tubular wire screen filter elements (60) suspended from an outlet chamber (42) into an inlet chamber (41) of a filter (10), is effected by the vertical vibration of helically-wound coil springs (65), one surrounding each filter element. All the springs are attached to a horizontal spider 70, which is itself vibrated vertically. The filter aid cake (including the filter residue) may be redeposited by liquid flow, or may be removed from the liquid and the liquid recirculated, or be drained off with the liquid.

    Abstract: 950,333. Filters for liquids. WINSLOW ENGINEERING & MANUFACTURING CO. May 15, 1962 [May 17, 1961], No. 18011/61. Heading B1D. A cartridge 11 for filtering contaminant from, and separating water from, hydrocarbon liquids, comprises a layer 34 of absorbent fibrous material, e.g. sisal, a layer 35 of non- woven fabric, e.g. cotton, felt or synthetic fibre that will filter out the fine contaminant from the hydrocarbon liquid, a spacer 38, e.g. coiled wire, or string, or expanded metal webbing between the said layers, and a layer 36 of water coalescing glass fibre, or glass wool bonded by a phenolic binder, which layer causes water tc fall under force of gravity into a sump 14. A suitable bonding material is used on the ends of the various media to retain them in the cartridge 11. The shape of a central cavity 18 is maintained by a coil spring 19. In another embodiment, Fig. 4, a droplet barrier 45 of, e.g. polyurethane, comprises a fourth layer, and a further such layer 57 assists coalescing of the water droplets. In a modification, Fig. 5 (no shown), the layers 45, 57 are replaced by a single such barrier of fine mesh monofilamen screen. In a modification of Fig. 1, (Fig. 6, no shown), such a barrier is located around the periphery of the filter cartridge.
