20090205301 | FILTER DEVICE IN PARTICULAR FOR AN EXHAUST SYSTEM OF AN INTERNAL COMBUSTION ENGINE - Cross-sectional geometries of filter elements for soot particle filters are described, allowing uniform loading of the filter element with soot. Starting with hexagonal cell shapes, other polygonal shapes are arranged around them. All the cross-sectional geometries have in common the fact that the cross-sectional area of all inlet channels is larger than the cross-sectional area of all outlet channels. | 08-20-2009 |
20090301048 | Filter for Removing Particles from a Gas Stream and Method for its Manufacture - A filter for removing particles from a gas stream has a filter pad with a coating which contains at least one of the following substances: (a) at least one aluminum oxide selected from alpha-, gamma-, delta- and theta-aluminum oxide, (b) hydrous aluminum oxide which is doped with silicon dioxide, at least one oxide of a metal of the 3 | 12-10-2009 |
20100263340 | FILTER ELEMENT, IN PARTICULAR FOR FILTERING EXHAUST GASES OF AN INTERNAL COMBUSTION ENGINE - A filter element, in particular for filtering exhaust gases of an internal combustion engine, includes mutually parallel flow channels, at least two filter segments being provided which each have a subset of flow channels, the filter segments having a spacing from one another and being interconnected via connecting device(s) arranged integrally with the filter segments. | 10-21-2010 |
