Filtering apparatus

Image Number 2 for United States Patent #5185019.

A filter tube assembly for a ceramic filter tube consisting of an annular elongated section from which a head extends. The head has a section whose outer surface is in the shape of a segment of a sphere which tapers out from the elongated section and merges into a cylindrical section. The assembly includes a stainless steel housing internally shaped to accommodate the head. Gaskets are interposed between the housing and the head which are structured cooperatively with the head to preclude dislodgement of the tube from the housing, to take up effectively the differential in thermal expansion between the tube and the housing, to prevent eccentric loading of the tube, to prevent the penetration of particulate into the housing and to seal asperities in teh surface of the tube.
