Patent number: 6574466Abstract: A process for establishing secure communication between particular communicating units via a channel of a telecommunication network encodes data embodying information to be selectively transmitted from a transmitter unit to one or more particular receiver units prior to transmission using an error detecting code enabling reliable recovery of the information on reception. For security reasons, the error detecting code used to encode the information is encrypted using an enciphering key defined by application of a time dependent variation law.

Patent number: 6190160Abstract: The invention relates to a process for combustion of a fuel with an oxygen-rich oxidant, in a combustion chamber (3), in which, cyclically: at least one principal variable representing the combustion in the said combustion chamber (3) is measured, and, as a function of the result of the measurement of the at least one principal variable, a control instruction for regulating the flowrates of fuel and oxidant to be injected into the combustion chamber (3) is determined. Then the regulating control instruction is applied in order to make the fuel burn with the oxidant in the chamber (3). Additionally at least one secondary variable associated with an operational constraint of the combustion chamber (3) or with a perturbation in the operation of the latter is measured, and for the determination of regulating control instruction, the measurement result of the at least one secondary variable is also taken into account. The invention is useful in glass furnaces, rotary furnaces, and incineration furnaces.Type: GrantFiled: July 2, 1999Date of Patent: February 20, 2001Assignee: L'Air Liquide, Societe Anonyme pour pour l'Etude et l'Exploitation des Procedes Georges ClaudeInventors: Isabelle Hibon, Jean-Francois Simon

Patent number: 6171100Abstract: Burner firing method and device are presented where an oxidizing oxygen-fuel burner is fired at an angle to the reducing air-fuel burner flame to reduce overall NOx emissions from high temperature furnaces. The oxidizing oxy-fuel burner stoichiometric equivalence ratio (oxygen/fuel) is maintained in the range of about 1.5 to about 12.5. The reducing air-fuel burner is fired at an equivalence ratio of 0.6 to 1.00 to reduce the availability of oxygen in the flame and reducing NOx emissions. The oxidizing flame from the oxy-fuel burner is oriented such that the oxidizing flame gas stream intersects the reducing air-fuel flame gas stream at or near the tail section of the air-fuel flame. The inventive methods improve furnace temperature control and thermal efficiency by eliminating some nitrogen and provide an effective burnout of CO and other hydrocarbons using the higher mixing ability of the oxidizing flame combustion products.Type: GrantFiled: September 20, 1999Date of Patent: January 9, 2001Assignees: American Air Liquide, Inc., L'Air Liquide Societe Anonyme pour l'Elude et l'Exploitation des Procedes George ClaudeInventors: Mahendra L.

Patent number: 4929266Abstract: A method for manufacturing glass wherein raw material is fed as a batch to a continuous glass-melting tank furnace, melted in a melting tank and passed to a refining tank via a submerged throat. The melt is heated in the refining tank to de-gas it, and then molten refined glass is delivered to a conditioning tank where it is brought to a desired working temperature. The refining tank is divided into upstream and downstream refining cells by a transverse sill. The melt in the upstream refining cell is heated to create a spring zone located towards the downstream end of that cell and a circulation of melt in that cell which feeds the spring zone.Type: GrantFiled: April 29, 1988Date of Patent: May 29, 1990Assignee: GlaverbelInventors: Daniel Cozac, Jean-Francois Simon
