Patent number: 9440888Abstract: Fabricating a composite material part comprises the steps of making a consolidated fiber preform, the fibers of the preform being carbon or ceramic fibers that are coated in an interphase formed by at least one layer of pyrolytic carbon (PyC) or of boron-doped carbon (BC). Obtaining a partially densified consolidated fiber preform, where partial densification comprises forming a first matrix phase on the interphase, the first matrix phase comprising a plurality of layers of self-healing material alternating with one or more layers of PyC or of BC. Continuing densification by dispersing carbon and/or ceramic powder within the partially densified consolidated preform and by infiltrating molten silicon or a liquid composition formed for the most part of silicon.Type: GrantFiled: November 22, 2012Date of Patent: September 13, 2016Assignee: HERAKLESInventors: Eric Bouillon, Eric Philippe, Andre Lafond, Franck Lamouroux

Patent number: 7628356Abstract: The invention relates to a yaw control device for an aircraft fitted with a supersonic nozzle having a rectangular or flat section comprising a supersonic throat extended by a diverging portion in which supersonic flow occurs. In order to enable the aircraft to be controlled in yaw in the absence of a vertical fin, the device of the invention makes use of jet control surfaces in the form of airfoils disposed in the diverging portion of the nozzle. The control surfaces are movable about respective pivot axes in order to generate a lateral force when in a deflected position, so as to enable the aircraft to turn about its yaw axis.Type: GrantFiled: June 28, 2006Date of Patent: December 8, 2009Assignee: Snecma Propulsion SolideInventors: François Buffenoir, André Lafond

Publication number: 20040166030Abstract: A biological specimen cassette comprising a base and a lid wherein the lid is pivotally mounted relative to the base. The lid so pivots into the base that, once in a closed position, the lid is included within the base thereby providing to the cassette, an overall thickness which is equal to that of the base. Similarly, the lid has a tab which does not extend beyond the dimensions of the base.Type: ApplicationFiled: February 26, 2003Publication date: August 26, 2004Inventors: Andre Lafond, Daniel Leblanc

Patent number: 6640981Abstract: A modular test tube rack for assembly with similarly constructed racks comprise a flat rectangular body displaying, in a first position, a series of wells extending from its top wall to its bottom wall and adapt to receive tubes therein. A pair of handles vertically extend at opposite end walls of the body, each handle having a lower portion adapted to tightly engage an extension on each end wall and a hand gripping upper portion. The lower portion has a bottom edge configured to anchor with the top edge of the handle of an underposed similarly constructed rack to thereby enable a stacking of two more of these racks. In one embodiment, the body displays a second series of wells extending from the bottom wall to the top wall whereby the body, when in a second position reversed relative to the first position, may also receive test tubes, the handles being reversably mountable to the end wall extension to still enable a stacking of racks in the second position.Type: GrantFiled: August 14, 2001Date of Patent: November 4, 2003Assignee: 3088081 Canada Inc.Inventors: André Lafond, Yanick Bertin

Patent number: 6601725Abstract: An integral assembly of a multiplicity of spaced reagent tubes arranged in an aligned series wherein the tubes are integrally linked to one another by connecting portions and to a corresponding multiplicity of independently spaced seal caps by a multiplicity of bands, each band having one end integral with a seal cap and an opposite end integrally connected to two adjacent tubes. The bands extend perpendicularly to the series of aligned tubes and include an oblique hinge portion which is deformable so as to allow the cap to be independently manipulatable to pivot angularly and to superimpose the open end of a tube for sealing.Type: GrantFiled: May 15, 2001Date of Patent: August 5, 2003Assignee: 3088081 Canada, Inc.Inventors: André Lafond, Yanick Bertin

Patent number: 6568544Abstract: A support assembly for receiving and holding a series of test tubes is formed of a base plate receiving the bottom ends of the tubes, an intermediate frame displaying an array of openings to receive the tubes and a top frame also displaying an array of tube receiving openings in vertical registry with the array of openings of the intermediate frame. The base plate and the top frame have outwardly extending opposite ends that are adapted to snappingly engage one another together with the opposite ends of the intermediate frame. The intermediate frame and the top frame include one or more removable frame sections each having openings of a given configuration to correspond to the configuration of tubes so that the support is adaptable to receive tubes of varying configuration. Similarly, the base plate has one or more removable sections to correspond to the configuration of the bottom ends of the tubes.Type: GrantFiled: May 22, 2002Date of Patent: May 27, 2003Assignee: 3088081 Canada Inc.Inventors: André Lafond, Yanick Bertin

Patent number: 6543717Abstract: The thrust device comprises a valve body (20) having a chamber (24) surrounding part of the needle, at least one gas admission opening (27) opening out into the chamber, and a gas outlet opening (25) opening out into the chamber and defined by a wall portion which co-operates with a nose portion (14) of a moving needle (10) to define an outlet section for gas leaving the chamber. Actuator means (40, 41, 43) control the position of the needle in the valve body by acting on a rear end portion of the needle. The nose (14) of the moving needle (10) has an aerodynamic concave profile (15) and the wall portion (29) which defines the outlet (25) from the chamber is shaped in such a manner as to be capable of directing the exiting gases essentially against the concave side of the nose of the needle, which needle acts as the main member for taking up thrust.Type: GrantFiled: December 22, 2000Date of Patent: April 8, 2003Assignee: Societe Nationale d'Etude et de Construction de Moteurs d'Aviation S.N.E.C.M.A.Inventors: Thierry Le Fur, Bernard Debons, André LaFond, André Dumortier
