| 20090126863 | Device, installation and method for aligning and/or assembling filtering elements - A device for aligning and/or assembling filtering elements, in particular of particulate filter, an installation for assembling a filter from filtering elements incorporating the device, and a method for aligning and/or assembling monolithic filtering elements, in particular for making a particulate filter. The device includes a back plate whereon are set the filtering elements, the back plate being for example fixed on a base plate, and walls laterally foldable upwards by a folding mechanism, such that the filtering elements are mutually maintained tightly when the walls are in an upper position. | 05-21-2009 |
| 20100308849 | DEVICE FOR DETECTING RADIAL CRACKS IN A PARTICULATE FILTER - 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. | 12-09-2010 |
