Patent EP-0287443-A1 (EP)
Title: Procédé de compensation d'un circuit à amplificateur de charge, notamment pour hydrophone piézoélectrique
Inventor: BILLET DANIEL
IPC: G01S7/529
Filed: 1988-04-08
Abstract: L'invention concerne la compensation de l'effet des paramètres extérieurs sur les capteurs piézoélectriques connectés à un amplificateur de charge. Elle consiste à utiliser une petite portion (36) de ce capteur (300) pour former le condensateur (22) de contre-réaction de l'amplificateur (310). L'effet de ces paramètres est alors le même sur le capteur et sur le condensateur. Elle permet de compenser les hydrophones en matériau polymère piézoélectrique.

Abstract: When converters are tapped, steel also runs out with the slag towards the end of the tapping. With a minimal amount of steel remaining in the converter, the proportion of slag also running out must be minimised in order to improve the accuracy of analytical sampling, the degree of purity and the output. The cause of slag also running out is essentially the formation of a vortex and a lowered channel above the tap hole, when the level falls below the critical steel bath level. According to the invention, a depression is therefore created around the tap hole, the depth of the depression being greater than the critical bath height for vortex formation and, to prevent the latter, the depression being provided with weirs, feeds for inert gas and/or coils for generating flows in the steel bath and measuring instruments to detect the slag also running out. The process provides that the depression is uniformly filled until the end of tapping, the stiffness of the slag is increased by means of lime if necessary and/or the melt is perturbed by pulsed introduction of inert gas and/or the vortex flow is perturbed by electromagnetic fields. By means of the novel device and the process, formation of the vortex is very largely prevented and therefore has the advantage of improving the accuracy of analytical sampling, the degree of purity and the output of steel in the tapping of converters. <IMAGE>

Un système de commande (25) fournit un signal de commande qui varie en fonction d'un signal (23) indicateur du mouvement differentiel inter-image et de l'inverse de l'occupation du tampon. Un récepteur de télévision numérique reçoit un signal d'image de télévision numérique et de préférence un signal d'état d'occupation du tampon de l'émetteur. On applique un signal filtré passe-bas de haute résolution à l'additionneur conformément à l'état du tampon et à l'indication du mouvement.

Abstract: An apparatus and method to determine with a high degree of precision the position of the inside wall of a translucent or transparent tube (10) comprises a laser beam at a wavelength for which the material being measured is transparent or translucent and a directing means (12) for aiming the laser beam toward the tube and normal to the axis of the tube while moving the aimed beam to traversely scan the tube. A light detection means (16), positioned to receive light polarized normal to the axis of the tube which light, having been reflected by the inside wall (14) and refracted by the tube, causes the detection means to generate signals. The signals are processed (23) to analyze when the light beam is reflected by and when the light is refracted at the inside wall (14) of the tube. The apparatus is also useful in connection with finding the position of the inside wall (14) of curved material of generally uniform thickness. The method includes the steps of aiming a beam of laser light polarized normal to the axis of the tube and intercepting the outside wall of the tube at a height substantially equal to the inside wall and normal to the axis of the tube (10) so that the laser light reflected by or refracted through the inside wall (14) can be detected and related to the transition point between reflection and refraction as a measure of the radius of curvature of the inside wall.

Abstract: The invention concerns a method wherein hydrochloric acid, which is used especially for pickling steel before zinc coating, is regenerated by mixing it with sulphuric acid. Heating the mixture and concentrating it with regard to sulphuric acid causes the hydrochloric acid to distil into vapor phase while the metals that have been dissolved in the pickling acid remain in the sulphuric acid. By condensating the distillates, the hydrochloric acid may be reused in the pickling process. The metal sulphate salt produced in evaporation is filtered and can be utilized in zinc manufacturing process.

Abstract: A method and apparatus for washing impurities such as phosphine, ammonia, hydrogen sulphide and/or arsine out of crude gases by means of sulphuric acid in at least one washing column is described. To overcome the disadvantages of known processes, such as formation of by-products which cause blockages and high equipment cost, it is proposed to circulate dilute sulphuric acid in an (n-2)th washing stage, n being greater than or equal to 3, and to circulate concentrated sulphuric acid in an (n-1)th washing stage, and to charge fresh concentrated sulphuric acid in an (n-1)th washing stage at the top of the washing column. A 3-stage process here represents a particularly economical solution. <IMAGE>

Abstract: Transforming Growth Factor-b (TGF-b) enhances the growth-inhibiting activity of tumor necrosis factor (TNF) or interferon-a (IFN-a) on immune cells and hematopoietic progenitor cells, as well as cancer cells. Thus, combinations of TGF-b with TNF or IFN-a are effec­tive for suppressing immune cell and hematopoietic pro­genitor cell growth, and are thus useful for treating cancer (e.g., lymphomas, leukemias, myelomas, adeno­carcinomas, etc.), autoimmune and chronic inflammatory diseases (e.g., rheumatoid arthritis, osteoarthritis, myasthenia gravis, lupus erythematosus, uveitis, etc.) hyperproliferative diseases (e.g., psoriasis vulgaris), and organ transplant rejection, and for protecting immune cells and hematopoietic progenitor cells from the lethal effects of cancer chemotherapy and radiotherapy.

Abstract: The invention relates to the monitoring of the spring-back of a tube (7), or other deformable elongate element, on it being bent by wrapping around a forming component (1), with clamping of the tube (in 5) at a portion (7c) located in front of the bend to be formed. 
<??>After producing the bend (7a), the portion (7c) of the tube located in front of this bend remains clamped, while its portion (7b) located to the rear of the bend (7a) is released. The extent of the spring- back is determined by a detection means (13) which carries out a measurement or a referencing on the released portion (7b) of the tube located to the rear of the bend (7a). The detection of the spring-back is made on rotation of the tube (7) and of the forming component (1) about the axis (2) of the bend (7a) by detecting the instant when the portion (7b) reaches a predetermined position. 
<??>This process enables the bending of the tube (7) to be resumed after detecting the spring-back.

Abstract: Les procédés connus employés pour la fabrication de matériaux de contact au CuCr sont des procédés faisant uniquement appel à la métallurgie des poudres, des procédés par frittage et infiltration ainsi que des procédés de la métallurgie par fusion. Seuls les matériaux produits par la métallurgie par fusion conviennent comme matériau de contact pour les contacteurs à vide à base de cuivre et de chrome. Dans le cadre de l'invention, un matériau de contact pour des contacteurs à vide, constitué essentiellement de cuivre (Cu) et de chrome (Cr) dans des proportions de 50 à 70% en poids de Cu et de 30 à 50% en poids de Cr, est fabriqué par un procédé consistant à comprimer et à fritter un mélange pulvérisé des composants jusqu'à ce qu'on obtienne une porosité fermée et à former ensuite à froid le comprimé fritté. On a pu démontrer que ce procédé permet d'obtenir, comme dans le cas de la fusion, une liaison intime et sans défauts des composants Cu et Cr par soudage à froid des constituants de la structure.
