20150082633 | TOOL AND METHOD FOR FRONTAL UNSCREWING OF A LINK NUT IN A TWIN-SPOOL TURBINE - A method for unscrewing a link nut of an HP rotor of a twin-spool turbine, including a front fan, an intermediate casing, a HP module with a HP rotor, and a LP turbine module, the intermediate casing including a support bearing for the HP rotor, the rotor being retained in the bearing by the link nut, the method including: placing an unscrewing tool in front of the link nut after having removed the fan and released access to the nut from the front; with rotation of the HP rotor locked and the frontal unscrewing tool including a socket spanner including teeth having a shape that complements that of teeth of the link nut, attaching a mounting for the socket spanner to the intermediate casing, the socket spanner being rotatably mounted on the mounting, and applying an unscrewing torque to the socket spanner. An unscrewing tool implements the method. | 03-26-2015 |

20110190627 | Method and Device for Marking a Medium, and Marker Usable in Such a Method - To mark an area of interest in a target medium, an initially inactivated and ultrasound-activatable optical marker is added to the medium, and then an ultrasound activation beam is emitted, being focused on the area of interest in order to locally activate the marker, which then colors the area of interest. | 08-04-2011 |
20120121516 | Emulsion Activatable by Ultrasounds and Method for Producing Same - The invention relates to an emulsion that can be activated by ultrasounds, comprising, in an emulsion in an aqueous solution, microparticles having a diameter of less than 10 μm and containing an active agent and a gaseous precursor in a liquid form, encapsulated by a first emulsifier. The microparticles contain nanoparticles smaller than 1 μm, in an emulsion in the gaseous precursor, each nanoparticle comprising an inner liquid that contains the active agent and is encapsulated by a second emulsifier. | 05-17-2012 |
