20090109590 | Self-protected solid-state electrical switching device - A self-protected solid-state switching device comprising first opening means connected in series with a first fuse link, means for measuring electric current and control means acting on opening and closing of said first opening means according to the value of a main electric current flowing through said switching device. Said device comprises at least a second fuse link connected in parallel with the first fuse link, at least second electric opening means being connected in series | 04-30-2009 |
20100182071 | High-voltage solid-state switch - A solid-state switch according to the invention is designed to be connected in series with a load. The switch comprises at least two electric switching means connected in parallel, measuring means designed to measure an electric voltage at the terminals of the electric switching means and a main current flowing in the load, and control means delivering a control signal to act on opening and closing according to the value of the main current. The state of conduction of the first electric switching means depends at the same time on the main current flowing in the load, on a control current, on a control voltage delivered by the control means, and on the gain of the first electric switching means. | 07-22-2010 |

20100043408 | METHOD FOR THE CALIBRATION AND MANAGEMENT OF AN EXHAUST LINE COMPRISING A PARTICLE FILTER - The invention relates to a method for the calibration and/or management of an exhaust line of a motor vehicle comprising a particle filter (X), said method comprising an initial step of measuring, over a representative population of the filter, the increase in the loss of load generated by a limited load of soot particles present in a filter, that is the threshold for the triggering of a filter regeneration phase; a step of measuring, in the absence of soot particles, the loss of specific load of the filter (X); and a step of determining, on the basis of the values obtained in steps a) and b), a limited value for the loss of load, that is the threshold for the triggering of a regeneration phase. The invention also relates to a system for managing an exhaust line comprising means for implementing said method. | 02-25-2010 |
20110256379 | BODY ASSEMBLED WITH A MACROPOROUS HARDENED CEMENT - An assembled ceramic body having blocks attached to one another by means of a seal, the lateral surface of the ceramic body possibly being coated with a peripheral coating, the seal and/or the peripheral coating including a set cement having less than 10% of inorganic fibers, as a percentage by weight based on the dry mineral matter, in a section plane perpendicular to at least one of the facing faces of the blocks assembled by said seal, having macropores with an equivalent diameter in the range 200 μm to 40 mm in a quantity such that the total surface area in said section plane occupied by said macropores represents more than 15% and less than 80% of the total surface area observed. | 10-20-2011 |

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 |

20110313147 | CHROMATOGRAPHIC MATERIAL FOR THE ABSORPTION OF PROTEINS AT PHYSIOLOGICAL IONIC STRENGTH - Ion exchange and hydrophobic interaction chromatographic materials are constructed by tethering a terminal binding functionality to a solid support via a hydrophobic linker. The backbone of the linker typically comprises sulfur-containing moieties. Suitable terminal binding functionalities are tertiary amines, quaternary ammonium salts, or hydrophobic groups. These chromatographic materials possess both hydrophobic and ionic character under the conditions prescribed for their use. The separation of proteins from crude mixtures at physiological ionic strength can be accomplished with a chromatographic material of this type by applying pH or ionic strength gradients, thereby effecting protein adsorption and desorption. | 12-22-2011 |
