Patent number: 8753722Abstract: Angular sectors of a cylindrical wall of a crucible for vitrification of waste, built in steel and subject to high temperatures, are coated with a mixture of mainly glass and ceramic, the coating being subject to a heat treatment comprising a step between 650° C. and 850° C. so as to perform surface melting of the mixture filling the open porosity, improving dielectric strength and the cohesion of the coating, but without producing any excessive thermal expansion or oxidation of the substrate which would lead to fast flaking of the coating.Type: GrantFiled: November 17, 2009Date of Patent: June 17, 2014Assignee: Areva NCInventors: Patrice Brun, Geoffroy Berard, Jacques Lacombe

Patent number: 8182146Abstract: A temperature measurement tube is composite and comprises a rigid shaft (1), which is cooled so as to shield it from corrosion and from the melt, and an end-fitting (15) housing a thermocouple (9) on the end of the tube and constructed from a noble metal, which is resistant to corrosion and to the high melting point. An alumina coating (13) is placed between the two metals in order to prevent any corrosion-inducing electrochemical exchange between them.Type: GrantFiled: November 30, 2006Date of Patent: May 22, 2012Assignees: Areva NC, Commissariat a l'Energie AtomiqueInventors: Patrice Brun, Jean-Francois Hollebecque, Jacques Lacombe, Valerie Petitjean

Patent number: 8119908Abstract: The electricity transmission device comprises prolonged rigid conductors made of copper, and also a connector comprising a network of flexible elements, such as brazed tubes with cooling channels for the conductors, that enables angular displacements between the successive segments and therefore gives a flexibility absorbing small displacements of the device. A lifting manoeuvre system is associated with the segments. The segments may be joined to other elements of the device through connections with jaws enabling slipping.Type: GrantFiled: February 9, 2007Date of Patent: February 21, 2012Assignees: Areva NC, Commissariat a l'Energie AtomiqueInventors: Jacques Lacombe, Patrice Brun, Thierry Flament, Eric Chauvin, Antony Prod'Homme

Publication number: 20090265131Abstract: One proceeds with indirect measurement of the temperature of a molten bath (1) of a viscous material such as glass by measuring a parameter such as the motor torque of a rotating mechanical stirrer (3) or the heating power extracted from its coolant water. One thereby dispenses with direct measurement of the temperature by a rod provided with a thermocouple and subject to difficult operating conditions.Type: ApplicationFiled: February 1, 2007Publication date: October 22, 2009Applicant: AREVA NCInventors: Patrice Brun, Jacques Lacombe, Yann Papin

Patent number: 6996153Abstract: Vertical segments of a side wall of a crucible for an induction furnace are assembled at an adjustable, invariable position by screws screwed into tapped holes of a flange common to all segments. A precise assembly is thus obtained producing no deformation and no internal stresses. The segments are coated with a ceramic coating for their protection and to prevent formation of electric arcs. Junction edges of faces are rounded to achieve the same effect. Water cooling boxes of the lower furnace hearth are similarly constructed. The apparatus can, as an example, be applied to vitrification techniques.Type: GrantFiled: January 31, 2003Date of Patent: February 7, 2006Assignees: Commissariat a l'Energie Atomique, Compagnie Generale des Matieres NucleairesInventors: Patrice Brun, Jacques Lacombe, Christian Ladirat, Francis Bousquet

Patent number: 6815572Abstract: The present invention provides a method of processing organic waste (D) in divided solid and/or liquid form, the method being implemented in a single reactor (1) containing a bath of molten glass (V) surmounted by a gas phase (G), the method comprising incinerating said waste (D) in the presence of oxygen at the surface (S) of said bath of molten glass (V), and in vitrifying said incinerated waste (D) in said bath of molten glass (V). In said method, and in characteristic manner, in addition to the oxygen delivered as oxidizer into said gas phase (G), oxygen is also injected into said bath of molten glass (V) in a quantity that is sufficient to minimize or to avoid any formation of metal within said bath of glass (V); advantageously in a quantity that is sufficient to minimize or to avoid any formation of metal within said bath of glass (V) and also to subject said bath of glass (V) to moderate stirring.Type: GrantFiled: May 24, 2001Date of Patent: November 9, 2004Assignees: Korea Electric Power Corporation, Societe General pour les Techniques Nouvelles - SGNInventors: Pierre Brunelot, Jacques Lacombe, Serge Merlin, Patrice Roux, Valérie Thiebaut, Kwan-Sik Choi, Myung-Jae Song

Patent number: 5841108Abstract: A tubular electrical element lying substantially in a plane is fixed under a heater plate of an electrical appliance. The ends of the element are connected to a thermal limiter disposed near the middle of the element to measure at least the temperature of the element and to disconnect the electrical power supply from the element if the measured temperature exceeds a predetermined value. A portion of the element extends substantially along the peripheral contour of the plate and the ends of the element extend towards the middle of the element.Type: GrantFiled: January 22, 1997Date of Patent: November 24, 1998Assignee: SEB S.A.Inventor: Jacques Lacombe

Patent number: 4605395Abstract: To treat hydrocephaly, an intracranial catheter is implanted in the head. It is connected to a tube fitted with a non-return valve and serves to divert the flow of cephalo-rachidian liquid to the peritoneum or to the right auricle of the heart. In accordance with the invention a hydraulic filter of non-linear variable impedance is connected in the tube in series with the valve. The filter maintains an average flow rate of the cephalo-rachidian liquid close to the physiological flow rate, but prevents sudden rushes of fluid flow, thereby permitting the intracranial pressure to vary in the short term in the normal manner over a characteristic period of about one second, while preventing said pressure from rising slowly in the long term, e.g. over a characteristic period of about one minute. This is done by a bead (160) which is housed in a cavity (161) extending between a proximal orifice (111) and a distal orifice (136). The distal orifice constitutes a leaky valve seat for the bead.Type: GrantFiled: January 13, 1984Date of Patent: August 12, 1986Assignee: Universite Rene Descartes (Paris V)Inventors: Christian S.
