Patent number: 9546115Abstract: A monolithic honeycomb element includes a collection of adjacent ducts of mutually parallel axes separated by walls made of a porous material, the element having, in transverse cross section, a polygonal, notably quadratic cross section delimited by exterior wall elements, wherein at least one corner of the polygon, has, along the bisector of the angle at the corner, an additional thickness, such that the total thickness of the external wall, likewise measured along the bisector of the angle at the corner, is greater than the mean thickness of the exterior walls by a factor of at least 1.43, the additional thickness being obtained at least in part by an additional quantity of porous material on the external face of the corner.Type: GrantFiled: September 12, 2012Date of Patent: January 17, 2017Assignee: SAINT-GOBAIN CENTRE DE RECHERCHES ET D'ETUDES EUROPEENInventor: Bernard Bouteiller

Patent number: 8557011Abstract: The invention relates to a honeycomb structure including a set of adjacent channels, each channel being in communication with upstream and downstream surfaces, respectively, via upstream and downstream openings, such that said set of channels forms cross-sectional upstream and downstream patterns on said upstream and downstream surfaces, respectively. According to the invention, at least one of the upstream and downstream surfaces has an error-proofing mark extending over fewer than 50 channels and making it impossible to completely stack any one of the upstream and downstream patterns onto the other, the outer perimeter of the upstream and/or downstream pattern being symmetrical or having an asymmetry that extends over fewer than 10 channels. The invention can be used in the filtration of particles contained it the exhaust gases of internal combustion engines, in particular diesel engines.Type: GrantFiled: July 9, 2010Date of Patent: October 15, 2013Assignee: General Electric CompanyInventor: Bernard Bouteiller

Patent number: 8038757Abstract: A block for filtering particles contained in an internal combustion engine exhaust gases, includes overlapping assemblies of adjacent input channels (14e) and output channels (14s), the input and output channels being alternately arranged so as to form, in cross-section, a checkered pattern, the overall volume of the input channels (14e) being greater than that of the output channels (14s). The filtering block is characterized in that at least one inner space (20e, 20s) of one channel (14e, 14s) includes at least one inner fin (30).Type: GrantFiled: August 22, 2005Date of Patent: October 18, 2011Assignee: Saint Gobain Centre de Recherches et d'Etudes EuropeenInventors: Sébastien Bardon, Bernard Bouteiller

Publication number: 20100308849Abstract: The invention relates to an assembly consisting of a device for detecting radial cracks in a particulate filter of the honeycomb type, of which the filtering part is made up of a porous inorganic material, said particulate filter comprising a single monolithic element or being obtained by combining a plurality of monolithic elements, the device being characterized in that it comprises an electrically conducting material arranged in the form of a strip or of a wire on at least one longitudinal part of the filter, secured to a monolithic element and/or to the coating cement or the jointing cement, and having an electrical conductivity greater than that of the material that makes up that part of the filter to which it is secured, and a strength less than or equal to that of the material that constitutes that part of the filter to which it is secured, and means of measuring the conductivity or the electrical resistance of the strip or wire of electrically conducting material.Type: ApplicationFiled: December 19, 2008Publication date: December 9, 2010Applicant: SAINT-GOBAIN CENTRE DE RECHERCHES ET D'ETUDES EUR.Inventors: Bernard Bouteiller, Arnaud Ballon, Anthony Briot, Gaetan Champagne, David Pinturaud
