Patent number: 11965075Abstract: This invention relates to a treatment process for a material chosen from among a polyamide, a polyester and a poly(meth)acrylate. According to the invention, this process comprises a step in which contact is made between this material and a polar organic solvent in a supercritical fluid. This invention also relates to a process for manufacturing a part from a material chosen from among a polyamide, a polyester and a poly(meth)acrylate in a divided form. Finally, the invention relates to use of the material treated by the treatment process and to use of the part manufactured by the manufacturing process in the low voltage, medium voltage or high voltage electrical industry.Type: GrantFiled: December 17, 2020Date of Patent: April 23, 2024Assignees: Commissariat à l'énergie atomique et aux énergies alternatives, Schneider Electric Industries SASInventors: Olivier Poncelet, Daniel Getto, Olivier Renard, Mehrdad Hassanzadeh, Romain Maladen, Karim Helal

Publication number: 20170152627Abstract: A method for marking a textile thread by a fluorescent element has the following successive steps: placing a textile thread and at least one fluorescent element in a reaction chamber, introducing a fluid into the reaction chamber, increasing the temperature and pressure in the reaction chamber up to a temperature and a pressure so as to transform the fluid into a supercritical fluid and to mark the textile thread by the fluorescent element. The fluorescent element is chosen from organolanthanide complexes.Type: ApplicationFiled: June 2, 2015Publication date: June 1, 2017Applicant: COMMISSARIAT À L'ENERGIE ATOMIQUE ET AUX ENERGIES ALTERNATIVESInventors: Aurélien AUGER, Sonia DE SOUSA NOBRE, Daniel GETTO

Patent number: 8342006Abstract: The invention relates to a method for detecting and/or quantifying water leaks in a water pipe, and to a device for realizing said method. The method of the invention comprises measuring the water flow rate in the pipe in at least two different locations, i.e., one downstream and one upstream relative to the suspected leak, the water flow rate being measured by injecting a tracing agent that modifies the water conductivity instantaneously at an upstream location and a downstream location relative to the suspected leak location, continuously measuring the water conductivity downstream from said locations and, from the conductivity values, calculating the water flow rates upstream and downstream relative to the suspected leak location in the pipe. The method of the invention can be used for quantifying a leak flow rate that can even be a very small one.Type: GrantFiled: November 27, 2007Date of Patent: January 1, 2013Assignee: Commissariat a l'Energie AtomiqueInventors: Daniel Getto, Patrick Burghoffer
