Patent number: 8533487Abstract: Embodiments include a system for processing logical clock values according to a secure maximum operation. The system may include a communication unit and a processing unit. The communication unit may be configured to receive an encrypted first value of a logical clock, send an encrypted blinded difference, receive an encrypted blinded maximum value, and receive a maximum value. The processing unit may be configured to access an encrypted second value of the logical clock, generate the encrypted blinded difference between the first value and the second value, provide an encrypted blinded first value and an encrypted blinded second value in an oblivious transfer protocol, and generate an encrypted maximum value from the encrypted blinded maximum value.Type: GrantFiled: September 30, 2009Date of Patent: September 10, 2013Assignee: SAP AGInventors: Florian Kerschbaum, Julien Jean-Pierre Vayssiere

Patent number: 8250146Abstract: A system may include a gateway that is configured to intercept messages being exchanged between multiple services, a message repository that is logically coupled to the gateway and that is configured to store the intercepted messages, a service description repository that is configured to store multiple service descriptions, where each of the service descriptions corresponds to one of the services, a rules repository that is configured to store mapping rules and an adaptation engine that is configured to generate a sequence of firing rules using the service descriptions and the mapping rules responsive to the intercepted messages, to generate one or more outgoing messages in response to the intercepted messages using the sequence of firing rules, and to detect at runtime an occurrence of a termination anomaly.Type: GrantFiled: May 15, 2008Date of Patent: August 21, 2012Assignee: SAP AGInventors: Julien Jean-Pierre Vayssiere, Wen Shin Kenneth Wang, Marlon G. Dumas, Chun Ouyang

Patent number: 4382817Abstract: A process for periodically and pneumatically stirring a bath of molten metal, wherein during the periods in which no stirring effect is required a fluid in gaseous state is injected through injection devices below the surface of the bath of molten metal in an amount sufficient to prevent blockage of the devices, whereas during the periods in which a stirring effect is required a fluid in liquid state which will vaporize quickly upon contact with the liquid metal is injected to provide an optimum amount of mixing gas with a minimum of injection devices.The process is advantageously used in converters for pneumatically converting pig iron into steel and in which oxygen is blown from above onto the bath of molten metal.Type: GrantFiled: January 2, 1981Date of Patent: May 10, 1983Assignee: Institute de Recherches de la Siderurgie FrancaiseInventors: Pierre Vayssiere, Jean-Claude Grosjean

Patent number: 4340208Abstract: The refractory piece permeable to gases according to the invention is designed to be incorporated in the inner refractory lining of a metallurgical container so that one of its surfaces will be in contact with the molten metal bath in said container, the opposite surface being equipped with means for introducing a gas under pressure.This piece, whose shape is generally hexahedral, consists essentially of a mass of nonporous refractory material that has a number of local discontinuities 8 extending throughout the piece along its height h between the surface in contact with the molten metal and the opposite surface. In an advantageous method of embodiment, the local discontinuities 8 are obtained by an assembly 1, in a metal casing, of nonporous refractory elements 2, in the form of plates and which are placed side by side along their large lateral surfaces, without any material gaskets or seals between them.The piece according to the invention is easy to make.Type: GrantFiled: April 24, 1980Date of Patent: July 20, 1982Assignee: Institut de Recherches de la Siderurgie FrancaiseInventors: Pierre Vayssiere, Charles Roederer, Jean-Claude Grosjean, Roland Grave, F.

Patent number: 4141723Abstract: Stainless steel is produced in a converter with a tuyere defining a central conduit and a peripheral conduit concentrically surrounding the central conduit, by blowing an oxidizing refining gas through the central conduit into a molten metal bath, the refining gas initially consisting of pure oxygen and being subsequently diluted by gaseous argon, and injecting liquid argon into the converter through the peripheral conduit, to refine the molten metal bath until it has attained a desired level of carbon.Type: GrantFiled: August 30, 1977Date of Patent: February 27, 1979Assignee: Institut de Recherches de la Siderurgie Francaise (IRSID)Inventors: Guy Denier, Pierre Vayssiere, Georges Giroud, Jean-Claude Grosjean

Patent number: 4101313Abstract: In the production of steel from pig iron melted and refined in a vessel, the pig iron is preheated in two phases. In the first preheating phase, the cold pig iron and hot gases recovered from the melting and refining vessel are moved simultaneously through a first and higher rotary tubular furnace whose lower open end is in communication with an upper open end of a second and lower rotary tubular furnace constituting a second preheating phase. The second furnace is heated from the outside to regulate the temperature of the pig iron to a desired value before it is introduced into the vessel from the second furnace.Type: GrantFiled: October 14, 1976Date of Patent: July 18, 1978Assignee: Institut de Recherches de la Siderurgie Francaise (IRSID)Inventors: Pierre Vayssiere, Aristide Berthet

Patent number: 4079184Abstract: A wall element for furnaces useful in all types of metallurgical furnaces but particularly in electric arc steel refining furnaces is comprised of a metallic block defining a cooling circuit in the interior thereof and a lining of refractory bricks anchored firmly to the cooled metallic block. The metallic block carries anchoring lugs projecting from the internal face of the block, each lug consisting of a foot portion and a retaining portion, which is constituted by an enlarged end of the foot portion opposite the internal face. Each refractory brick has a face adjacent the internal face of the metallic block and defining a recessed portion of a cross section matching that of a corresponding one of the anchoring lugs.Type: GrantFiled: August 16, 1976Date of Patent: March 14, 1978Assignee: Institut de Recherches de la Siderurgie Francaise (IRSID)Inventors: Bernard Bahout, Jean-Pierre Motte, Pierre Vayssiere
