20110238351	METHOD AND SYSTEM FOR CORRECTING A TEMPERATURE MEASUREMENT SIGNAL - A method including digitally modelling a temperature measured by a sensor by using a modeled signal and estimating a lag error signal for the sensor from the modeled signal and a signal obtained by filtering the modeled signal, the filter having as a parameter an estimate of a time constant of the sensor, and correcting the measurement signal delivered by the sensor by the estimated lag error signal. The time constant of the sensor is estimated as a function of time from the measurement signal and the modeled signal.	09-29-2011
20110246151	METHOD AND A SYSTEM FOR ESTIMATING A STREAM TEMPERATURE IN A TURBOJET - An estimation method that can estimate a stream temperature in a turbojet including: digitally modeling the stream temperature with help of a modeled signal; and correcting the modeled signal with help of an error signal, a signal obtained after correction representing an estimate of the stream temperature. When predetermined conditions relating to at least one operating stage of a turbojet and to temperature stability are satisfied, the error signal is updated from the modeled signal and from a measurement signal of the stream temperature as delivered by a temperature sensor.	10-06-2011

20110282119	PROCESS FOR THE PRODUCTION OF A FUEL BASE FROM AN ETHYLENE FEEDSTOCK IMPLEMENTING AT LEAST ONE OLIGOMERIZATION STAGE IN THE PRESENCE OF A HOMOGENEOUS CATALYTIC SYSTEM - This invention describes a process for the production of bases for fuels (such as diesel and/or kerosene) from a C2 ethanol feedstock, whereby said process comprises at least a first stage for oligomerization of said feedstock into at least one hydrocarbon effluent that comprises a mixture of olefins that for the most part have between 4 and 30 carbons, whereby said olefin mixture comprises a C10-C24 fraction that has a mean linearity that is greater than 60%, in the presence of a homogeneous catalytic system that comprises at least one metal precursor that is selected from among the group that is formed by titanium, zirconium, hafnium, nickel and iron, taken by themselves or in a mixture, a second stage for oligomerization of at least a portion of the effluent that is obtained from stage a), into at least one hydrocarbon effluent that comprises a mixture of olefins that for the most part have between 4 and 30 carbon atoms, with said olefin mixture comprising a C10-C24 fraction that has a mean linearity that is less than 50%, in the presence of a homogeneous catalytic system that is identical to or different from the one that is used in stage a).	11-17-2011

20110174353	INSTALLATION SYSTEM FOR PV MODULES - A mounting system for photovoltaic modules includes at least two profile-shaped cross rails arranged parallel to each other and configured to hold several PV modules. Each cross rail includes plane supporting surfaces. The PV module is mounted by placing it onto the at least two cross rails so that the at least two holders lay flat on the plane supporting surfaces of the at least two cross rails. The PV module is then moved in a joining direction perpendicular to the cross rails while lying on the plane supporting surfaces so that either a recess engages with an integrated protrusion or a protrusion engages with an integrated recess. A retaining safety device is disposed between at least one cross rail and its corresponding holder and is configured to counteract a move against the joining direction.	07-21-2011
