METHOD FOR PREPARING A VACCINE COMPOSITION COMPRISING AT LEAST ONE ANTIGEN AND AT LEAST ONE ADJUVANT
Publication number: 20100233196Abstract: Method for preparing a vaccine, comprising—a step a) of preparing an adjuvant composition by dispersing, in a physiologically acceptable aqueous solution, at least one inverse latex or a powder of polymer resulting from the atomization of said inverse latex; —a step b) of mixing the composition obtained in step a) into an antigenic medium, intended to form a vaccine composition.Type: ApplicationFiled: October 6, 2008Publication date: September 16, 2010Inventors: Laurent Dupuis, Olivier Braun -
Publication number: 20080316005Abstract: In an intelligent centralized control panel, in particular for motors in which case it is known under the name of iMCC, communications with the outside are performed by powerline carrier current or PLC. The wiring of the control panels can thereby be greatly reduced. To enable this type of communication to be used in dense systems containing a large number of line starters and therefore a large number of parallel-connected carrier current interfaces, the invention proposes inserting a preferably electronically adjustable impedance in series with the PLC conversion device. Advantageously, an adjustment algorithm enables the values of the added impedances to be optimized according to the geometry and position of the different interfaces.Type: ApplicationFiled: June 10, 2008Publication date: December 25, 2008Applicant: Schneider Electric Industries SASInventors: Olivier Coutelou, Erick Contini, Laurent Dupuis
