A filter cartridge comprises a body of sintered material having a star-shaped profile and a substantially constant wall thickness. The body has a folded or corrugated configuration with the corrugations extending longitudinally parallel to the axis or along a helix or screw-thread pattern. The ribs or corrugations can be symmetrical about axial planes of the body and, in an embodiment of the invention, are parallel thereto.

Filter cartridge

A filter cartridge has a fluid-permeable support body formed externally with ribs and is closely surrounded by a 'folded' (e.g. corrugated) sheath of sintered material. The support body may likewise be formed of sintered material and preferably the sheath and support body are sintered together.

Filter cartridge with folded filter sheath

A process for producing composite bodies consisting of discrete particles, embedded in a metallic embedding material, in which the particles are positioned relative to the embedding material and the resulting composite is subjected to isostatic compression at pressures which suffice to cause the particles to be embedded.
