Title: Ailette de guidage de sortie au montage elastique
Inventor: CIOKAJLO JOHN JOSEPH
IPC: F01D9/04
Filed: 1989-07-26
Abstract: Un élément annulaire coulé intérieur de support 46 est monté concentriquement dans un élément annulaire coulé extérieur de support 48 extérieur pour l'assemblage d'une multitude d'ailettes de guidage de sortie 54 s'étendant radialement à l'intérieur du trajet d'écoulement d'un moteur à turbine à gaz. Les ailettes sont reliées élastiquement aux éléments intérieur et extérieur de support pour contrôler et limiter la charge de compression des ailettes provoquée par les contraintes thermiques pendant le fonctionnement du moteur. Une interconnexion élastique de fixation qui convient plus particulièrement pour emploi avec des ailettes en céramique comprend un ensemble à embases 76; 94 boulonné et fixé qui maintient les forces de compression tant radiales que circonférentielles agissant sur les ailettes à tout instant, malgré les différences des taux de dilatation thermique entre matériaux en métal et en céramique. Application aux moteurs à turbine de performances élevées.

Title: Passive prosthesis for tympano-ossicular chain
Inventor: CLAUDE DELEURME
IPC: A61F2/18
Filed: 1992-03-06
Abstract: Such a prosthesis comprises a member for mechanical transmission of the tympanic vibration to the stapes (stirrup), intended to remedy deficiencies of the tympano-ossicular chain. According to the invention, the prosthesis (18) includes a support element (19), solidly attached to the wall (30) of the cavity of the middle ear and defining a fixed axis of articulation, and a mobile element (29, 30) mounted pivoting on the support element about this axis of articulation and including two bearing points (31, 32), one of which comes into contact with the malleus (hammer) (4), and the other of which comes into contact with the plate of the stapes (14). The ratio of the distances between, on the one hand, the axis of articulation and the point of contact with the stapes (31) and, on the other hand, the axis of articulation and the point of contact with the malleus (32) is a predetermined ratio greater than one, so as to produce, by lever effect, a passive mechanical amplification of the tympanic vibration and to transmit this amplified vibration to the stapes.
