Title: Procede pour la conduite d'un four metallurgique de  fusion et dispositif de mise en oeuvre
Inventor: DE SAINT-MARTIN LUCIEN
IPC: C21B13/12
Filed: 1984-01-31
Granted: 1988-01-19
Abstract: Procédé pour la conduite d'un four métallurgique de fusion et dispositif pour sa mise en oeuvre. Selon l'invention, on introduit dans la partie supérieure du four la charge solide composée par des matières ferrifères à fondre et une quantité déterminée d'agent carboné et on soutire à la partie inférieure du four la fonte liquide obtenue par passage au travers de la charge solide d'un flux gazeux circulant du bas vers le haut et insufflé dans le four par des tuyères latérales. L'invention se caractérise en ce que l'on enfourne, avec les matières ferrifères, la quantité d'agent carboné au moins nécessaire à la carburation souhaitée de la fonte et en ce que l'on insuffle par les tuyères latérales un courant gazeux non oxydant, ou très faiblement oxydant, préalablement chauffé à haute température, de préférence au moyen de torche à plasma, de manière que sa chaleur sensible échangée avec la charge solide soit suffisante pour assurer la fusion de celle-ci ou la fusion d'une partie prépondérante de celle-ci. L'invention permet une économie de matière énergétique non renouvelable et s'applique préférentiellement à la fusion, dans les fours du type cubilot, des matières riches en fer telles que les ferrailles, éponges de fer, etc.

Abstract: Abstract of the Disclosure A hierarchical message channel storage of a digital switching system which is connected to time division multiplex transmission lines includes at least a small-capacity high-speed memory and a large capacity low-speed memory.  A control section performs switching using the high-speed memory when a circuit switching call is received.  However, when a packet switching call is received, the control section accesses the high-speed memory to temporarily stores transmission data in the high-speed memory and performs switching for one or output transmission lines for the control section accesses the high- and low-speed memories to temporarily store data in the low-speed memory through said high-speed memory so as to perform switching for one of said output transmission lines.  In this case, the access cycles of the high-speed memory have circuit/packet switching call cycles and switching program cycles.  A single storage is commonly used for the circuit switching call requiring writing data at a high speed, the packet switching call requiring storing a great amount of data, and the switching program.

Abstract: FAST RECOVERY BIAS CIRCUIT     Abstract A programmable bias circuit for use with a data limiter circuit is described.  The limiter and bias circuit are coupled to a portable data receiver which is adapted to communicate in a coded system.  Frequency disparities between a transmitted word sync signal and the portable data terminal local oscillator signal will cause a DC offset voltage in the received data signal. The programmable bias circuit is controlled by a decoder within the portable data terminal.  If the terminal is in an idle state, the programmable bias circuit will be set to rapidly follow offset voltage shifts until a transmitted word sync signal has been detected.  After word sync has been detected, a slower, more stable time constant circuit is programmably activated for the duration of the digital data message.  The fast time constant circuit is activated at the end of the received data signal.

Abstract: ABSTRACT:          "Method of liquefying a gas and liquefier for carrying out the method".            A gas at superatmospheric pressure is supplied via a first pre-cooling heat exchanger to a cryogenerator and is condensed there, while the condensate is then con-ducted through a liquid separator and is cooled and sub-cooled, respectively, in a second heat exchanger which is situated in liquid already produced in a thermally insu-lated reservoir. The sub-cooling is effected by means of a pressure controller downstream of the second heat exchanger and is regulated by the adjustment of the user pressure (second pressure). The cold for the first heat exchanger is extracted from the evaporated gas in the reservoir which was caused to evaporate by the second heat exchanger.          The method is used inter alia in liquefiers for nitrogen, hydrogen, argon, methane, etc.

Abstract: ABSTRACT           Power transmission to a remote consuming device, especially for underseas applications including towed arrays, static arrays, submersible links to submersible vehicles, or surveillance devices, links to divers, and dunking sonars, uses on the transmission medium an optical fibre.  This fibre has a thickness in the range 150-300um, i.e. it is of the so-called fat type, and is a long wavelength fibre for conveying light whose wavelength is in the range of 0.7 to 1.7um.  The light source uses lasers or super-luminescent diodes, a preferred light source being an array of individual laser diodes which are pulsed and/or cooled to improve power handling capacity.  These diodes each feed optical energy into a short length of optical fibre and these fibres are coupled via an optical coupler into the main transmitting fibre.  At the receiving end another optical coupler feeds via individual fibres an array of detectors each of which is preferably a photo-voltaic cell formed of layers of suitable doped indium phosphide and indium gallium arsenide.  Each such cell has its own output electrodes and these cells are connectable in series, parallel or series/parallel dependent on the desired output.

Abstract: HOMOGENEOUS FLUORESCENCE IMMUNOASSAY USING              A LIGHT ABSORBING MATERIAL                 ABSTRACT OF THE DISCLOSURE      A method for separation-free solid phase immuno-assay of an analyte includes contacting an anti-analyte attached to the surface of a solid support with the analyte, a light absorbing material and a fluorescent tracer for the analyte.   The resulting mixture is incubated.  The method includes applying excitation light to the mixture and time resolved measurement of fluorescence emission from the tracer.          All excitation light and fluorescence emission are absorbed by the light absorbing material except that absorbed and emitted by the tracer bound to the anti-analyte whereby the only fluorescence emission detected  is from the bound tracer.  Since free tracer in the fluid phase of the assay medium does not emit fluorescence, separation of the bound and free fractions is unnecessary.  The invention in-cludes a kit of materials useful in performing an immunoassay in accordance with the method of the invention.
