| 20110146229 | Integration of a Surface Heat Exchanger to the Wall of an Aerodynamic Flowpath by a Structure of Reinforcement Rods - Setting in place of one or several coolers in the wall of a secondary flow of a bypass turbomachine. The wall extends from an intermediate casing toward a leading edge of a separator nose between a primary flow and the secondary flow. The wall includes a series of support arms attached to an intermediate casing, distributed over the perimeter of the wall and directed upstream. A series of surface air-oil heat exchangers forming wall segments are arranged end-to-end on the support arms, so as to form an annular wall. A shroud having a leading edge is arranged and fixed in the area of the upstream edges of the heat exchangers, so as to complete the wall. The support arms include hydraulic connectors connected to one another on each arm, adapted to cooperate with corresponding connectors in the area of the heat exchangers and in the area of the intermediate casing. | 06-23-2011 |
| 20110150634 | Integration of an Air-Liquid Heat Exchanger on an Engine - A bypass axial turbomachine includes a fan, a low pressure stator stage, a high pressure stator stage, the compressors being traversed by a flow referred to as primary flow of the turbomachine, at least one passage of discharge flow rate controlled from the primary flow in one of the stator stages toward the secondary flow, a heat exchanger of the surface air-oil (ACOC) type arranged flat on or in the wall surrounding the stator stages and defining the internal surface of the secondary flow, directly downstream of the junction of the passage of the discharge flow rate with said wall, so as to be run through by the secondary flow enriched with the discharge flow rate. | 06-23-2011 |

| 20080206049 | BLADE ANGLE SETTING FOR A TURBOMACHINE - A straightener blade for a turbomachine, comprising a platform arranged at a radially external end of the blade and adapted to be engaged in a annular groove of a housing, and a threaded rod radially extending outwardly from the platform and adapted to pass through an orifice of the housing in order to receive a fixing nut, the upstream and downstream edges of the platform each comprising a protrusion extending in the plan of the platform in order to limit the rotation of the platform in the groove when the nut screwed on the threaded rod is tightened. | 08-28-2008 |

| 20100050276 | Transgenic non-human animal models of apoptosis-mediated conditions - A transgenic non-human animal whose genome comprises a stable integration of a transgene that encodes at least one Fas-ligand protein operably-linked to a tetracycline-inducible promoter includes cells that express the transgene and undergo apoptosis. The transgenic non-human animal can be used to screen for compounds that inhibit apoptosis and to identify cells that are capable of differentiating in vivo. | 02-25-2010 |
