20100052232 | FRICTION DEVICE FOR CONTROLLING FORCE, AND A FRICTION DAMPER COMPRISING SUCH A DEVICE - Friction device includes at least two members, one of which is mobile, or potentially mobile, in terms of relative displacement with respect to the other under the action of an external stimulus. The relative displacement is liable to cause the relative displacement of two friction surfaces subjected to pressing forces, so as to convert the external stimulus into a friction force and to thus control the displacement of the mobile or potentially mobile member. The pressing forces are produced by pre-stressing mechanisms and the members are able to act on the effects of the pre-stressing mechanisms so as to use the resultant effect of the relative displacement of the mobile or potentially mobile member to reduce the pressing forces. | 03-04-2010 |

20110039073 | DAMPING SKIN FOR PROTECTING COMPOSITE PARTS - Damping skin for protecting composite parts includes a composite material having at least two superposed layers, namely a first layer formed from the juxtaposition of hollow spheres, which is intended to be applied and fixed, either directly or indirectly, to the surface of the part to be protected and a second layer covering the first and formed from a wall made of a material having plastic deformation properties. | 02-17-2011 |
20110272536 | COMPOSITE L-SHAPED FITTING AND METHOD AND MOULD FOR THE PRODUCTION THEREOF - The invention relates to an L-shaped fitting obtained after molding a composite material, including two portions defining an angle therebetween and having holes formed therein for connecting the two portions using an attachment device, and having side reinforcements in the form of brackets. At least one portion has a concave curved profile on the inner side of the fitting, and the hole(s), formed in the portion having a concave curved profile on the inner side are each formed along an axis radial to the curvature. | 11-10-2011 |
20110277919 | METHOD OF MANUFACTURING A COMPOSITE PART, AND RESULTING PART - The invention relates to a method for manufacturing a composite part intended for being subjected, via at least one attachment point, to pulling and/or compression forces. The method includes: winding fibers on a hub so as to form a portion of the wall of the part, and creating an externally convex rounded area at the location intended to form the area for applying the pulling and/or compression forces. The forces are radial thereto. The method also includes placing an insert on the convex rounded area, the insert including the attachment point or a mechanism for rigidly connecting the attachment point, and continuing to wind fibers so as to form the rest of the wall, while covering a portion of the insert and leaving the attachment point or the mechanism for rigidly connecting the attachment point accessible. | 11-17-2011 |

20120167344 | SHOCK-ABSORBER DEVICE - The invention relates to a shock-absorber device intended to connect two parts, one part moves relative to the other part, owing solely to an initial temporary thrust provided by a driving device, thereby shifting from an initial position to an end position. The device includes a mechanical system connecting the parts in relative movement, which also includes a kinetic energy accumulator designed to be supplied by the above-mentioned initial thrust, and to return at least the exact amount of energy required to allow the mobile one part to reach the end position. | 07-05-2012 |
20130129956 | PART MADE OF A COMPOSITE, ITS MANUFACTURING PROCESS AND CONNECTING ROD OBTAINED BY THIS PROCESS - A part made of a composite is intended to be subjected, through at least a point of attachment and in cooperation with connectors, to tensile and/or compressive forces. The part includes a monolithic part having a winding of fibers oriented and embedded in a matrix, and a tubular body, wherein an attachment point, based at one end of said tubular body takes the form of a strap forming a loop turning about an axis perpendicular to the axis of the tubular body, and wherein an internal wall and/or the external wall of the loop is designed to cooperate with a portion of the connector in tension and/or in compression along one or more directions. | 05-23-2013 |
20130287479 | MULTI-BRANCH FITTING MADE OF COMPOSITE MATERIAL AND METHOD OF MANUFACTURING SUCH A MULT-BRANCH FITTING - A multi-branch fitting includes at least three branches, molded from a composite material and, more precisely, from a fiber-reinforced thermoplastic or thermoset matrix.
