20090054227 | METHOD FOR OBTAINING A HOMOGENEOUS FILTERING STRUCTURE FOR A CATALYTIC APPLICATION - The invention relates to a method of obtaining a homogeneous filtering structure for a catalytic application, which can be used as a particulate filter in an internal combustion engine exhaust line, said structure comprising a plurality of honeycomb filter elements in which a homogeneity criterion characteristic of the constituent support material of said elements, in the absence of a catalytic coating, is determined in a prior step, and then the elements making up the structure are selected by means of this homogeneity criterion so as to obtain a structure suitable for homogeneous deposition, within an element and from one element to another, of a catalyst for treating the pollutants in gas phase. | 02-26-2009 |
20090120062 | METHOD FOR THE NON-DESTRUCTIVE CONTROL OF A PARTICLE FILTER AND ASSOCIATED DEVICE - A nondestructive method for detecting internal defects of a filter, for example a catalytic filter, and a device for implementing the method. The method may be used in particular for treating a gas laden with soot particulates. The filter includes a honeycomb filter element or a plurality of honeycomb filter elements. In the method the presence or absence of the defects is determined by measuring a propagation of a gas stream such as air through the filter element or elements. | 05-14-2009 |
20090217762 | METHODS FOR CONTROLLING AND MAKING PARTICLE FILTERING DEVICES - One subject of the invention is a process for checking the robustness of a particulate filter intended to be used in the exhaust line of a diesel engine, comprising the steps consisting in, having first determined the soot mass limit of said filter, loading a new filter with a level of soot at least equal to two times and at most equal to three times said soot mass limit, then making said filter undergo a severe regeneration then, in any order, determining the filtration efficiency of said filter, measuring its pressure drop and comparing it to the pressure drop of the new filter, measuring its level of cracking, and finally checking its integrity after a mechanical stress. Another subject of the invention is a method for diagnosing the robustness of a filter. | 09-03-2009 |
20090297407 | STRUCTURE AND CATALYTIC FILTER FOR FILTERING A GAS COMPRISING A HYDROPHOBIC OR OLEOPHOBIC CEMENT - The invention relates to an assembled structure that can be used, after deposition of a catalyst, for filtering a gas loaded with soot particles and pollutants in the gas phase in which the cement used as a coating cement and/or as a joint cement comprises, at least at the surface, a hydrophobic or oleophobic material. | 12-03-2009 |
20150044263 | Kit comprising two separate compositions, notably for cosmetic application - A kit comprising two separate compositions (A) and (B). Composition (A) is an aqueous gel with a viscosity of less than 11 Pa·s and contains at least one capsule including: a liquid core with at least one active ingredient and a gelled envelope totally encapsulating the liquid core. The gelled envelope includes at least one polyelectrolyte in the gelled state. Composition (B) includes a depolymerizing agent. | 02-12-2015 |
