Patent number: 8932009Abstract: A device for supporting a ring of a gas turbine, the ring configured to surround mobile blades of the turbine which are driven by a gas stream flowing upstream to downstream. The device includes at least one upstream hook facing upstream, to be housed in an upstream groove of the ring, opened toward the downstream direction, and at least one downstream hook facing downstream, to be housed in a downstream groove of the ring, opened toward the upstream direction. The hooks are protected and clearances at apexes of the blades are more easily controlled. The device further includes, upstream from the upstream hook, a mechanism injecting cooling gas to cool the upstream hook and/or includes, downstream from the downstream hook, a mechanism injecting a cooling gas to cool the downstream hook.Type: GrantFiled: September 2, 2010Date of Patent: January 13, 2015Assignee: TURBOMECAInventors: Christophe-Olivier Moraines, Frederic Philippe Jean-Jacques Pardo

Publication number: 20040235049Abstract: The invention concerns a device for presentation of peptides or of proteins, which can be used as a “polypeptide chip” for the miniaturised detection of molecules structurally or functionally complementary to the said polypeptides. This device consists of a flat support onto which the polypeptides are covalently bonded, this bonding between the polypeptides and the support resulting from the formation of a semicarbazone bond. The semicarbazone bond results in particular from the reaction between polypeptides bearing an aldehyde or ketone function and a support functionalised with semicarbazide groups. The invention also concerns the process for preparation of the supports and for attaching polypeptides onto these supports and also the use of the devices thus obtained as polypeptide chips.Type: ApplicationFiled: June 28, 2004Publication date: November 25, 2004Inventors: Oleg Melnyk, Helene Gras-Masse, Christophe Olivier, Jean-Olivier Durand, Claude Auriault, Xavier Duburco, Ahmed Bouzidi, Jean-Michel Garcia, Ouafaa El-Mahdi
