    Abstract: A filter element 10 for purifying fluids having a filter medium 11, an enclosure member 12, and a rod 13. The filter medium 11 has folds 14, which may be zigzag-shaped, and which define a fold height 15 and a pleat surface 16. At right angles to folds 14 extend end faces 17, which represent the course of the folds 14. The enclosure members 12 are arranged on the end faces 17. To support the folds 14, the rod 13 pierces through the pleat surfaces 16 of the folds 14 creating joints 19. These joints 19 are sealed, e.g., by additional seals or by fusing the filter medium to the support rod or the support rod to the filter medium.

    Abstract: Use of a disposable filtration capsule with a non-occluded membrane filter element in the place of a standard spiral wound cartridge allows for the more rapid and quantitative filtration, recovery, and quantitation of microorganisms in liquid, particularly surface waters, well water, tap water, and the like. The capsule allows a severe reduction in the water sample size tested, substantially minimizes risks of cross-contamination, and provides a leak-proof vessel for shipment. Risk of infection of laboratory personnel and time of analysis are both reduced. Costs of measuring contamination by microorganisms such as Giardia and Cryptosporidium is lowered significantly while increasing the accuracy and dependability of the measurement.

    Abstract: An air filter comprising a sheet of filter material folded in a zig-zag configuration. A hardenable material is dispensed in a flowable state onto the sheet. The hardenable material has a varying thickness such that upon hardening, it holds the folds of the sheet apart in a selected orientation. The hardenable material may comprise glue to also secure the folds together. An air penetrable sheet can be secured to the fold edges at one or both sides of the filter.

    Abstract: A pleated paper filter element has the configuration of the frustrum of a cone with the pleats extending lengthwise of the sloping wall of the cone and has pleat separation dimples embossed into the paper from which the element is made, the height of said dimples being graduated lengthwise of the element so as to provide controlled pleat separation over at least most of the length of the element.

    Abstract: A filter element has a zigzag-folded filter medium. Filter medium sections joined by a fold edge define an intermediate fold space, respectively, with a fold base and fold peaks opposite the fold base. An elongate support section is arranged in the intermediate fold space on a filter medium surface of one of the filter medium sections. The support section extends perpendicular to the fold edges between fold base and fold peak. The support section has a height extension perpendicular to the filter medium surface that increases in longitudinal direction of the support section from fold base to fold peak. The support section has a free side facing away from the filter medium surface. The support section has a width extension parallel to the fold edges. The width extension decreases parallel to the filter medium surface and perpendicular to the longitudinal direction from fold peak to fold base.
