Patent number: 9494514Abstract: In systems and methods for analyzing traces of airborne compounds, the air to be analyzed is circulated for a given length of time through a small-diameter analysis tube while lowering the temperature of the air at the entrance to the analysis tube. Condensation and deposits of compounds are formed on the inner walls of the analysis tube. A scraping liquid is circulated through the analysis tube to scrape off the deposits. The compounds in the deposits are concentrated at the front of this liquid. The front of the liquid is then analyzed to identify the compounds.Type: GrantFiled: April 26, 2013Date of Patent: November 15, 2016Assignee: FlowgeneInventors: Bruno de Vandiere, Claude Debroche, Nicolas Garnier

Patent number: 7501639Abstract: An optical device (1) includes a cavity (2) for which at least part is ellipsoidal with a first focus (F1) and a second focus (F2). The device includes means of presenting a medium containing components to be analyzed in the cavity at the first focus, and the device also includes means of transporting an excitation light beam in the cavity along a path also passing through the first focus (F1) to illuminate the medium at the first focus. The ellipsoidal part of the cavity includes a wall reflecting light emitted by the medium in response to the excitation light beam, and the device includes means (5) of collecting said emitted light at the second focus (F2).Type: GrantFiled: December 10, 2004Date of Patent: March 10, 2009Assignee: FlowgeneInventors: Claude Debroche, Hervé Crespeau, Bruno De Vandiere

Patent number: 7411671Abstract: A medium is analyzed for the search for an odorous biological molecule characteristic of a specific substance in an environment to be studied comprising the steps of: exposing a component containing at least one olfactory biological receptor, capable of selectively attaching the type of odorous molecule sought, to an atmosphere taken from the environment to be studied; irradiating that component by means of an incident laser radiation having a wavelength chosen in the ultraviolet close to the absorption wavelength for the olfactory receptor, to cause the excitation of a resonance Raman scattering in the irradiated component; and analyzing the Raman spectrum obtained to determine whether or not it corresponds to the Raman spectrum of the olfactory receptor having attached an odorous molecule of the type sought in the atmosphere sampled, so as to identify any presence of the specific substance mentioned in the environment to be studied.Type: GrantFiled: September 15, 2006Date of Patent: August 12, 2008Assignee: Flowgene SAInventors: Bruno De Vandiere, Claude Debroche, Francis Galibert

Patent number: 5971050Abstract: The apparatus for the manufacture of a reinforcement from a thread deposited directly in its final position by projecting lengths of the thread for laying the thread onto a receiving surface (S). The apparatus includes an assembly (5) comprising rollers (15) for the advancing of thread (1), a rotary conduit (2), a knife (3) for cutting the thread and freeing a length (10) upon each turn of said rotary conduit (2), and a thread guide (4) to receive the cut lengths of thread. The thread guide comprises deflectors (43) exerting a pressure on the thread. The pressure of the deflectors can be adjusted by screws (7).Type: GrantFiled: November 25, 1997Date of Patent: October 26, 1999Assignee: SedeproInventor: Claude Debroche

Patent number: 5505802Abstract: The laying of pieces 40 of cord 4 is assured by a laying tube 30 which receives the cord by placing its inlet facing the outlet of a cord distributor, the knife 85 of which cuts the cord just upstream of the laying tube 30. At the end of the laying tube 30 there is disposed a laying head 32 which is displaced transversely along the support 1 on which the reinforcement is built. The angle of laying of the cord is adjusted by judiciously coordinating the transverse speed of displacement of the head 32 and the speed of rotation of the support 1.Type: GrantFiled: November 7, 1994Date of Patent: April 9, 1996Assignee: SedeproInventors: Claude Debroche, Daniel Laurent

Patent number: 5362343Abstract: The tire reinforcements are made from a single cord, a section (40) of which is advanced over a rigid core (2) until at least its central portion is opposite its final position on the support, whereupon folders (5) apply the section (40) radially against the core (2) by means of tappets (50) which act on the length (40) in the manner of a finger. The repetition of the same cycle as many times as there are lengths of cord in the reinforcement makes it possible to produce the complete reinforcement.Type: GrantFiled: February 4, 1994Date of Patent: November 8, 1994Assignee: SedeproInventor: Claude Debroche

Patent number: 5281289Abstract: The reinforcements for tires are made from a single cord (4) laid by a laying head (3A) which describes a path of any type surrounding the rigid core (2) which constitutes a rigid support on which the tire is progressively built. The path comprises a laying zone during which the laying head (3A) applies a length of cord. Between two successive passes of the laying head (3A), the rigid core (2) turns by an amount corresponding to the laying pitch.Type: GrantFiled: June 12, 1992Date of Patent: January 25, 1994Assignee: SedeproInventors: Claude Debroche, Daniel Laurent

Patent number: 4952259Abstract: A process for producing a tire reinforcement is characterized by the fact that each reinforcement cord is projected individually into its place in the reinforcement. For this purpose, a machine is used which comprises laying members comprising essentially a rotary conduit which projects the cord by a radially outer extremity of the conduit and rollers which impose a linear speed of laying of the cord.Type: GrantFiled: September 27, 1988Date of Patent: August 28, 1990Assignee: Compagnie General des Etablissements MichelinInventors: Claude Debroche, Daniel Laurent
