摘要:
A method for making a pleated structure having a pleated shape memory is provided which includes the steps of: providing a material in a pleated structure having a plurality of substantially parallel folds; folding the material along a plurality of axes substantially perpendicular to the first plurality of folds so as to provide a folded structure defining wall portions between folds along the plurality of axes and having face portions at the folds; heating the material in the pleated structure so as to provide a heated material; and cooling the heated material so as to provide the material with shape memory toward the pleated structure. The material is preferably a filter media and the pleated structure is preferably a filter pack structure.

Fluted filter media includes filter material having a plurality of flutes formed therein having alternating ends of adjacent flutes closed to force fluid through filter material. A first embodiment of the filter media includes tapered flutes which have the open ends of the flutes larger in cross-section than the closed flutes, wherein the upstream open flutes converge toward the downstream end and the upstream closed end flutes diverge toward the downstream end. A second embodiment includes filter media which is asymmetric formed with dissimilar upstream and downstream flute cross-sections with larger flute openings to the upstream side of the filter. A third embodiment includes filter media with an upstream edge crushed to improve flow at the upstream edge. A fourth embodiment includes filter media with the upstream sealing material recessed from the upstream edge for reducing effects from blockages at the upstream edge of the filter.

The invention relates to a structure element (1, 6, 10, 14, 31) of a device for the treatment of corrosive materials in heat and stress conditions. The structure element is comprised of monomers which are mass polymerized in a closed mold, said element being comprised of a single piece so as to seal the corrosive material when the element is placed in the device and when an external stress is exerted on said device.
摘要:
Ein Filterelement hat eine Trägerplatte (10) mit einer um eine Filterkammer-Vertiefung (12) herumlaufende Montagenut (24). Ein diese Vertiefung (12) überdeckender Filtertuch-Zuschnitt (28) hat einen angeformten Montagerahmen (26), der in der Montagenut (24) einsitzt. Auf diese Weise erhält man ein einfaches, rasches und faltenfreies Anbringen des Filtertuches an der Trägerplatte (10) und eine Flüssigkeitssperre beim Rand des Filtertuch-Zuschnittes (28).
摘要:
In the filter element (E), a multiplicity of tubes (3) each formed of filtering material and having a substantially circular cross-section are arrranged side by side in a tubular assembly with the axes of the tubes lying parallel to one another; inter-tube openings are closed (52) at one end of the tubular assembly which serves as an inlet for a fluid to be filtered, whereas intra-tube openings are closed (53) at the opposite end of the tubular assembly; and the total cross-sectional area of all the inter-tube openings is smaller than the total cross-sectional area of all the intra-tube openings, but larger than the minimum cross-sectional area of a path through which the fluid is supplied to the tubular assembly. Specifically, one or more filtering materials (1,2) including a plurality of tubes (3) each having a substantially circular shape cross-section and connecting portions (12,22) interconnecting the adjacent tubes (3) are rolled into a spiral shape to provide the tubular assembly with the axes of the tubes arranged side by side parallel to one another.
摘要:
Gezeigt und beschrieben ist eine Filterplatte aus Kugelgraphitguß für Filterpressen, welche mit einem korrosionsbeständigen Überzug (9) versehen ist. Zur Erzielung einer den hohen Druckwechselbelastungen über lange Zeiten standhaltenden Filterplatte ist vorgesehen, daß der Überzug (9) zumindest an den dem Filterpressenschließdruck ausgesetzten Flächen (5, 6, 8) der Filterplatte aus einer im Metallspritzverfahren, z. B. Flammspritzverfahren, aufgebrachten Metallschicht besteht.
