Abstract: The invention relates to a device for measuring dynamic parameters of an aircraft progressing over an airport zone. The aircraft is in the phase of rolling along a traffic lane. The traffic lane comprises ground markings and notably a center line. The device includes at least one means for acquiring images (101), and means (102) for measuring the deviation of the aircraft with respect to the center line on the basis of the acquired images.

Abstract: The present invention relates to a method and a device for monitoring the minimum flying altitude of an aircraft.

Abstract: The present invention refers to an information-displaying unit (1) which has a body of a determined geometrical shape internally with an illumination system having in the narrower portions thereof (12) an arrangement for installation of water atomizing nozzles of a body climatization system, and a pedestal (14) to house the components of said system. The right side portion (10) and the left side portion (10?) of the information-displaying unit (1) have an arrangement for installation of an information-displaying device (11).

Abstract: A method of locally repairing parts coated with a thermal barrier including a ceramic outer layer and a metal underlayer of alumina-forming alloy for protecting the substrate against oxidation and for bonding with the ceramic outer layer, includes: defining the zone for repair with a mechanical mask adapted to the shape of the part and the zone for repair; scouring the zone for repair so as to remove the ceramic, the alumina layer, and the damaged portions of the underlayer; supplying materials for repairing the underlayer to the repair zone by subjecting the partially-scoured part to metal deposition by use of an electrical current; and subjecting the part to a heat treatment in order to enable the added metals to diffuse into the remaining underlayer in the repair zone for repair and to enable a surface film of alumina to form. After the underlayer has been reconstituted, the zone for repair is again defined by a mechanical mask and a new ceramic layer is deposited thereon.

Abstract: The invention relates to a multimeric molecule which can imitate a natural multimeric proteinaceous ligand. The invention also relates to a multimeric molecule as defined above which is characterised in that it has the following general formula: A-Xn, wherein: n is equal to 3, 4, 5 or 6; A denotes a chemical group which is functionalised by at least three amine functions or COOH functions; and X denotes a D, B-D or B(D)-D? group, in which B is a spacer and D and D? are peptides or pseudopeptides corresponding to a sequence which is derived from the ligand and selected from residual matter forming the interface with the receptor and which can interact with the receptor.

Abstract: A communications installation includes at least one cellular communications network that does not have an NGN architecture and to which communications terminals are connected. When the installation receives (F1), from a calling mobile terminal (T1), a request to set up a multimedia connection with a called terminal (T2), it attempts to set up that multimedia connection (F3-F4) and, if it fails to do so, it attempts to set up an audio connection between the calling and called terminals (F5-F9).

Abstract: The invention provides a method of locally repairing parts coated in a thermal barrier constituted by a ceramic outer layer (5) and a metal underlayer (3) of alumina-forming alloy for protecting the substrate (1) against oxidation and for bonding with the ceramic outer layer (5), characterized by the following steps: a) defining the zone (6) for repair with a mechanical mask (8) adapted to the shape of the part (1) and the zone (6) for repair; b) scouring the zone (6) for repair so as to remove from said zone the ceramic, the alumina layer (3b), and the damaged portions of the underlayer (3); c) supplying materials for repairing the underlayer (3) to said zone (6) by subjecting the partially-scoured part to metal deposition by means of electrical current; and d) subjecting the part to heat treatment in order to enable the added metals to diffuse into the remaining underlayer in the zone (6) for repair and to enable a surface film (3b) of alumina to form.

Abstract: The invention relates to a method of overall repair for a part (1) coated in a thermal barrier constituted by a ceramic outer layer (5) and a metal underlayer (3) of alumina-forming alloy, the method being characterized by the following steps: a) subjecting the metal part (1) for repair to thermochemical treatment under fluorine-containing halogen gas for a length of time that is sufficient to eliminate the aluminum contained in the underlayer (3) and any oxides and sulfur compounds that might be present at the surface of the part (1) and in cracks (6), thereby causing the ceramic layer (5) to be removed and causing the part (1) to be passivated; b) restoring mechanical integrity to the part (1) by methods of repairing any cracks (6) by adding material; c) enriching the surface of the part in aluminum, if necessary; and d) depositing a new layer (5) of ceramic. The invention is particularly applicable to the blades of the high pressure turbine of a turbomachine.

Abstract: The present invention refers to an information-displaying unit (1) which has a body of a determined geometrical shape internally with an illumination system having in the narrower portions thereof (12) an arrangement for installation of water atomizing nozzles of a body climatization system, and a pedestal (14) to house the components of said system. The right side portion (10) and the left side portion (10′) of the information-displaying unit (1) have an arrangement for installation of an information-displaying device (11).
