Title: Device for continuous casting in vertical charge of a melting metal
Inventor: COURBE PIERRE
IPC: B22D11/04
Filed: 1999-11-16
Abstract: The invention concerns a device for continuous casting in vertical charge of a melting metal in the form of slabs, using a copper ingot mould (1) extended by a preheater (2) made of refractory material, the preheater (2) being positioned above the ingot mould (1) such that the liquid steel level, or meniscus (S), is located during the continuous casting operation in said refractory material preheater (2) and not in the copper ingot mould (1) proper. Between the copper ingot mould (1) and the preheater (2) is arranged a joint element made of refractory material consisting of bars (3), (4), (5), (6), (7), (8). The bars are positioned such that their assembly defines a joint element with an internal shape similar to that of the ingot mould and whereof the inner surfaces are the extension of the ingot mould corresponding inner surfaces, with a choice of dimensions such that the ratio of a bar transverse cross-section, expressed in mm2, to the length of said bar, expressed in mm, is not less than 2.4 mm. Moreover, the bars are parallelepiped in shape and their cross-section has a height/length ratio ranging between 0.4 and 0.6. Each bar (4), (6) is supported against a rear stop (12), (13) serving to position it in perfect alignment, allowing for the mechanical assembly clearances, with the ingot mould surface whereof it constitutes the extension and prevent it from being pushed backwards by the slab, and each bar (4) is machined (R) to receive a maintaining clamping claw (9), the latter ensuring the double function of pressing the bar vertically so that it remains in contact with the ingot mould top edge during the oscillating motion of the latter, and to prevent the bar from moving away from the alignment with the ingot mould surface whereof it is an extension by moving towards the slab centre, in particular at the start of the operation of continuous casting in vertical charge.

Abstract: The device is used in the archiving of big data volumes in computer systems in long automated medical researches. It provides control of the process of information exchange between different kinds of magnetic tape ministorage devices (MTMS) and microcomputers. It is possible to work with several of them simultaneously lasting by reduced program control. The device contains two programmable parallel interfaces. The first is connected to an evenness control circuit and through buffer amplifiers to storage inputs and inputs for control of MTMS. The second interface is connected to a comparing circuit, outputs for the condition of MTMS and through a buffer- to outputs for the reproduction of MTMS. Part of the inputs of the first programmable parallel interface are connected to a priority coder, which outputs are connected to a control register, the output of which is connected to an input for processing system interruptions of a microcomputer. The information tapes of the control register are connected to the information tapes of a programmable timer, the two programmable parallel interfaces and to a part of the input/output tapes of a duplex buffer, the remaining tapes of which are connected to the information tapes of the microcomputer.

Title: Analyse automatisee bidimensionnelle d'echantillons biologiques et autres
Inventor: DOVICHI NORMAN J
IPC: C12Q1/02
Filed: 2000-03-10
Abstract: L'invention concerne un procédé et un appareil permettant de séparer et de détecter des composants dans un échantillon, notamment des échantillons biologiques. L'échantillon est soumis à une première technique de séparation, par exemple l'électrofocalisation, l'électrophorèse, ou analogue. Après cette première phase de séparation, on divise l'échantillon en fractions, chacune étant ensuite soumise à une seconde technique de séparation, par exemple une chromatographie. Les composants sortant de la seconde phase de séparation sont détectés. On peut ainsi appliquer une technique de séparation bidimensionnelle. Les deux techniques de séparation sont différentes, par exemple l'électrofocalisation et une technique capillaire de gel SDS. Les première et seconde techniques de séparation sont convenablement effectuées dans les premier et second capillaires. Un autre aspect de l'invention concerne une rampe raccordant des paires de capillaires de façon à présenter plusieurs systèmes de séparations doubles fonctionnant en parallèle, par exemple 96 paires de capillaires. L'invention concerne en particulier la présentation d'une séparation de solution élevée et d'une sensibilité de détection élevée de composants dans des échantillons biologiques.

Title: Marchepied a relevage manuel pour camionnettes
Inventor: WATSON BRAD E
IPC: B60R3/02
Filed: 2000-05-10
Abstract: L'invention concerne un ensemble marchepied (20) comprenant un support (26) de montage monté dans un chariot inférieur de la camionnette. Un marchepied (30) est monté pivotant sur le support de montage. Le marchepied est capable de tourner entre une position rentrée dans laquelle le marchepied est disposé à côté du support de montage et une position de fonctionnement dans laquelle le marchepied se projette du support. Un ressort hélicoïdal est monté entre le support et le marchepied de manière à contraindre en continu le marchepied dans la position rentrée. Un mécanisme à cliquet, comportant un cliquet d'arrêt, une came et un ressort excentré, est monté entre le support et le marchepied. Le mécanisme à cliquet bloque le marchepied dans la position de fonctionnement en réponse à la rotation du marchepied de la position rentrée à la position de fonctionnement. Lorsque l'ensemble marchepied se trouve dans la position de fonctionnement, un utilisateur peut se tenir debout dessus pour accéder au châssis de la camionnette. Le mécanisme à cliquet débloque également le marchepied en réponse à une rotation excessive du marchepied dans la position de fonctionnement. Une fois débloqué, le marchepied effectue automatiquement une rotation en sens inverse dans la position rentrée. Lorsqu'il se trouve dans la position rentrée, l'ensemble marchepied est dissimulé sous la camionnette.

Title: Removal of hydrogen sulfide from fluid streams with minimum production of solids
Inventor: KENT VAN A
IPC: C01B32/50
Filed: 1989-10-31
Abstract: ABSTRACT       Fluid streams containing hydrogen sulfide such as a geothermal steam or a sour gas stream are contacted with an aqueous solution of a polyvalent metal chelate and a bisulfite whereby the hydrogen sulfide is converted to free sulfur and then to soluble sulfur compounds.  The metal chelate is reduced to a lower oxidation state metal chelate and reduced metal chelate is subsequently oxidized with air back to the higher oxidation state and reused.  The bisulfite is formed by combustion of a hydrogen sulfide portion of the fluid stream and subsequent absorption of the sulfur dioxide formed thereby in a two-stage countercurrent scrubber operating at conditions favorable for high bisulfite and low sulfite formation and selective away from carbon dioxide absorption.

Title: Plug-type clasp for pieces of jewelry
Inventor: BUNZ GEORG
IPC: A44C11/02
Filed: 1990-01-17
Abstract: A plug-type clasp for pieces of jewerly, in particular for necklaces, composed of a housing in which a sleeve is movable under the force of a spring. The sleeve has a receiving opening into which a connecting element can be inserted through a front-end opening of the housing and locked there. Both the front-end opening of the housing and the receiving opening of the sleeve are eccentrically offset from each other, so that the connecting element can only be inserted into the housing, and locked there, only after the sleeve has been pulled back against the force of the spring. Removal of the connecting part can take place in the correspondingly reversed order. Activation of the sleeve for unlocking the plug-type clasp takes place by means of an operating button, laterally guided in a longitudinal hole of the housing, so that the actual connecting areas of the plug-type clasp for pieces of jewelry, in particular necklaces, remain free of pulling stresses during the operation of the plug-type clasp. With the exception of the spring and sleeve, no other movable parts are required.
