Publication number: 20180208739Abstract: Layered double hydroxides organo-modified by 3-(4-hydroxyphenyl)propionic acid (HPPA), by 2-(4-hydroxyphenyl)ethylsulfonic acid or by a hydroxyphenylpropenoic acid, and to composite polymer materials having same. The composite materials are advantageously made of biosourced polymers such as poly(butylene succinate). These composite materials have improved properties over the polymers that make up the composition thereof, and over the composites of the prior art.Type: ApplicationFiled: May 19, 2016Publication date: July 26, 2018Applicants: CENTRE NATIONAL DE LA RECHERCHE SCIENTIFIQUE, UNIVERSITÉ BLAISE PASCAL- CLERMONT II, ALMA MATER STUDIORUM- UNIVERSITA DI BOLOGNA, ECOLE NATIONALE SUPÉRIEURE DE CHIMIE DE CLERMONT FERRANDInventors: Fabrice LEROUX, Vincent VERNEY, Laura SISTI, Annamaria CELLI, Grazia TOTARO

Patent number: 9810614Abstract: The method for evaluating the compactness of a layer of railroad ballast near a railroad tie includes at least one step of taking at least two measurements (11,11a,11b) of the penetration resistance (Qd) of the ballast (13) near one and the same railroad tie (10), and a step of calculating the mean value (Qdmean) of these measurements (11,11a,11b) of penetration resistance (Qd). Also provided are a device for implementing such a method and a method for predicting the settlement of the ballast of a railroad track including a step of evaluating the compactness of a ballast near a railroad tie.Type: GrantFiled: October 28, 2013Date of Patent: November 7, 2017Assignees: SNCF RESEAU, UNIVERSITE DE MONTPELLIER 2 SCIENCES ET TECHNIQUES, UNIVERSITE BLAISE PASCAL-CLERMONT II, LE CENTRE NATIONAL DE LA RECHERCHE SCIENTIFIQUE (CNRS)Inventors: Gilles Saussine, Juan Carlos Quezada, Pierre Breul, Franck Radjai

Publication number: 20170283697Abstract: A method for producing a photo-luminescent material, including the following steps: (1) producing, according to a sol-gel method, a sol and then a gel of first precursors of a first substance from the sol; (2) crushing the gel; (3) optionally, annealing the gel in order to form first particles of the first substance of which the average size is between 1 pm and 20 um; (4) producing a colloidal dispersion of second particles of a second substance, different from the first substance or identical to the first substance, of which the average size is between 5 nm and 400 nm; (5) mixing the colloidal dispersion with the sol in step (1) before forming the gel or with the first particles after step (3); and (6) annealing the mixture obtained in step (5), resulting in an increase in the compactness of the mixture, the average size of the second particles after annealing being between 100 nm and 900 nm.Type: ApplicationFiled: August 12, 2015Publication date: October 5, 2017Applicants: Aledia, Universite Blaise Pascal-Clermont II, Centre National de la Recherche Scientifique, Sigma ClermontInventors: Abdelhay Aboulaich, Geneviève Chadeyron, Rachid Mahiou

Patent number: 8554501Abstract: A method and device for the non-intrusive determination of the electrical power consumed by a subscriber installation. From the sampled values of the supply current and supply voltage that are delivered to the installation, constituting a consumption signal, the sampled values are grouped in successive observation time windows; the poles and residues of the consumption signal are discriminated in each current window using the pencil method, the set of poles and residues associated with at least one singular value representing a combination of signatures of separate electrical loads; at least the active power consumed by a subset of electrical loads in operation is calculated, over at least the duration of the current observation window, the sum of the active powers consumed by each electrical load satisfying a consumed power function linking these poles and residues.Type: GrantFiled: October 2, 2009Date of Patent: October 8, 2013Assignees: Electricite de France, Universite Blaise Pascal Clermont II, Landis + Gyr, Centre National de la Recherche Scientifique—CNRSInventors: Alioune Diop, Thierry Jouannet, Khalil El Khamlichi Drissi, Hala Najmeddine

Publication number: 20120031194Abstract: The invention relates to a method of diagnosing the operation of a water purification installation of the filter medium device type, the material of the filter medium being made up of particles, the method including the following steps: a characterization step of characterizing at least one physical and/or mechanical parameter of the filter medium device to establish a permeability value Ks (expressed in m/s); a comparison step of comparing said established permeability value Ks with a predetermined range [kmin; kmax] of permeability values representing a satisfactory operating state of the purification installation; and a diagnosis step during which the filter medium device is assigned an operation indicator according to the result of the comparison step. Applications include non-collective sanitation (NCS) systems and stand-alone sanitation systems.Type: ApplicationFiled: January 18, 2010Publication date: February 9, 2012Applicants: UNIVERSITE BLAISE PASCAL- CLERMONT II, VEOLIA EAUInventors: Christian Vignoles, Pascal Molle, Alain Lienard, Laurence Rolland, Pierre Breul, Fathe Bouteldja, Daniel Boissier

Patent number: 7622422Abstract: A method of preparing an ionic conducting gel in solid form, known as ionogel. The method includes a step of mixing an ionic liquid with at least one molecular precursor containing at least one hydrolyzable group, if necessary in the presence of an acid, such as a carboxylic acid. The mixture is subsequently left to stand for one or more days until a gel is formed by polycondensation of the molecular precursor(s). The gel contains the aforementioned ionic liquid and can be set, in particular in transparent monolithic solid form.Type: GrantFiled: July 2, 2004Date of Patent: November 24, 2009Assignees: Centre National de la Recherche Scientifique, Universite Montpellier II, Universite Blaise Pascal Clermont IIInventors: André Vioux, Jean Le Bideau, Marie-Alexandra Neouze, Fabrice Leroux
