20140084018 | Annular Seal, And Mold For Manufacturing Such A Seal - An annular seal is provided. The annular seal is configured to be lubricated, allowing for automatic dispensing in dispensers, without the risk of clogging the dispensers or of building up with other seals. The annular seal has a determined thickness, made of an elastically deformable material, having a seal plane at mid-thickness and an axis of revolution perpendicular to the seal plane, and having: a so-called “inner” surface, turned toward the axis of revolution, and extending over a height of between ⅙ and 22/50 of the thickness on either side of the seal plane, and a so-called “contact” surface extending over the rest of the seal. The seal includes, on the contact surface, at least one spot protuberance. | 03-27-2014 |

20110062954 | A PROBE FOR INSPECTING THE SURFACE OF A CIRCUMFERENTIAL SLOT IN A TURBOJET DISK BY MEANS OF EDDY CURRENTS - A probe for eddy current monitoring of the surface of a circumferential slot formed in a turbojet disk. The probe includes a stem fastened to a support and a first multi-element sensor constrained to move with the stem and configured to be inserted into the circumferential slot to perform the inspection, and a second multi-element sensor. The two multi-element sensors are disposed back to back, and the stem of the probe is mounted to pivot about its own axis to enable the two multi-element sensors to be inserted in the slot. | 03-17-2011 |

20080297148 | DEVICE FOR NON-DESTRUCTIVE EDDY CURRENT INSPECTION OF A HOLE FORMED IN A CONDUCTIVE PART - Using eddy currents to inspect a hole that is possibly not rectilinear and/or of section that is not circular. The inspection device comprises a stick shaped and dimensioned to be capable of being engaged in said hole, at least one arm hinged to a support fastened to one end of the stick, an eddy current sensor being embedded in said arm, and resilient means for urging the arm outwards against the inside surface of the hole. | 12-04-2008 |
20080297149 | IDENTIFICATION OF POINTS OF INTEREST IN A REGION OF THE SURFACE OF A PART AND APPLICATION TO THE OPTIMIZATION OF THE PATH AND OF THE ANGULAR POSITION OF EDDY CURRENT PROBES - The invention relates to the identification of points of interest in a region of the surface of a part, by bringing a surface reference into intimate contact with said region, said surface reference consisting of a thin film sufficiently flexible to conform to the region, the thin film supporting tracks made of electrically conductive material, the passage of an eddy current probe over a track delivering a significant signal representative of the track, this representative signal corresponding to a point of interest thus identified in said region. | 12-04-2008 |

20090148454 | Peptide Domain Required For Interaction Between The Envelope of a Virus Pertaining to The Herv-W Interference Group and an Hasct Receptor - The invention relates to a peptide domain required for interaction between the envelope of a virus pertaining to the HERV-W interference group and a hASCT receptor, comprising an N end point and a C end point. Said peptide domain is defined, at the N end point thereof, by a pattern formed by the amino acids L (Z)-proline-cysteine-X-cysteine in which Z is any amino acid, is a whole number between 2 and 30, and X is any amino acid, and at the C end point thereof, by a pattern formed by the amino acids serine-aspartic acid-Xa-Xb-Xc-Xd-Xe-aspartic acid-Xf-Xg-(Z) in which Xa, Xb, Xc, Xd, Xe, Xf, Xg are any amino acids, Z is any amino acid, B is a whole number between 15 and 25, preferably 20. The peptide domain comprises, between the N end point and the C end point, at least one pattern selected from the following patterns: a pattern formed by the amino acids cysteine-X2-X3-X4-X5-X6-cysteine in which X2, X3, X4, X5, X6 are any amino acids, and a pattern formed by the amino acids cysteine-X7-X8-X9-X10-X11-X12-X13-X14-X15-cysteine-trytophane in which X7, X8, X9, X10, X11, X12, X13, X14, X15 are any amino acids. | 06-11-2009 |
