Patent number: 9632051Abstract: A sensor for determining gas content of a two phase fluid flowing in a flow line, the sensor including a sleeve configured to be arranged in the flow line in a stream of fluid. The sleeve includes a plurality of measurement electrodes that, in pairs, define a plurality of subdivision spaces subdividing a flow section of the sleeve. The sensor also includes switch and measurement members coupled to the measurement electrodes to control switching of each subdivision space of the sleeve between a measuring state and a non-measuring state. The switch and measurement members are configured to selectively switch the state of each of the subdivision spaces independently of one another.Type: GrantFiled: July 31, 2012Date of Patent: April 25, 2017Assignees: SNECMA, CENTRE NATIONAL D'ETUDES SPATIALESInventors: Philippe Nivet, Alain Bruere, Didier Matarin

Patent number: 9151684Abstract: The invention relates mainly to a test bench (10) for a radial bearing (14) suitable for being interposed between two members (12, 16) that are movable relative to each other in rotation, the test bench being characterized in that it comprises a radial force measurement device (18) for measuring radial forces exerted on said bearing (14), a radial acceleration measurement device (20) for measuring radial accelerations to which said bearing (14) is subjected, and an electronic calculation unit (26) in communication with the radial force measurement device (18) and with the radial acceleration measurement device (20). The invention also relates to a method of establishing a behavior relationship for the radial bearing (14).Type: GrantFiled: April 4, 2014Date of Patent: October 6, 2015Assignees: SNECMA, CENTRE NATIONAL D'ETUDES SPATIALES CNESInventors: Philippe Nivet, Fabien Tessier, Laurent Fabbri, Valerie Begin
