Beschreibung
Zusammenfassung:	Apparatus for filtering solid particulates from suspension in fluid streams (especially carbon particulates from exhaust gas of diesel engines) comprising a honeycomb filter with thin porous walls defining cells extending therethrough, with the transverse cross-sectional shapes of the cells forming a repeating pattern of geometric shapes without interior corner angles of less than 30 DEG and with alternate cells forming an inlet group and an outlet group. The inlet group is open at the inlet face and closed adjacent the outlet face. The outlet group is closed adjacent the inlet face and open at the outlet face. Each cell of each group shares cell walls only with cells of the other group. The walls have a volume of substantially uniform interconnected open porosity and a mean pore diameter of the pores forming the open porosity lying within the area defined by the boundary lines connecting points 1-2-3-4 in FIG. 4.
