Patent EP-0455749-A1 (EP)
Inventor: HUBER WILLIAM D
IPC: G11B20/10
Filed: 1990-01-23
Abstract: Un circuit détecteur de canal de relecture permet de récupérer des données numériques d'une forme d'onde de relecture produite par une tête d'enregistrement magnétique. Le circuit détecteur comprend un filtre en direct (20) qui affine le bord montant et brouille le bord descendant d'une impulsion magnétique isolée d'entrée. Des techniques (23) de récation quantifiée sont ensuite utilisées pour produire une forme d'onde compensatrice (0) sensiblement complémentaire du bord descendant brouillé de l'impuslion magnétique de l'impulsion magnétique isolée (8). La forme d'onde complémentaire est additionnée (21) à la sortie du filtre en direct afin de produire une forme d'onde (E) qui constitue essentiellement une fonction discontinue. Cette fonction correspond à une seule transition numérique, du négatif au positif ou du positif au négatif dans une séquence numérique de sortie. La forme d'onde est ensuite limitée par un comparateur (22) afin de produire la séquence voulue de sortie. L'affinement du seul bord montant de l'impulsion magnétique d'entrée et l'utilisation de techniques de réaction quantifiée permettent de conserver la largeur de bande totale du système et d'obtenir une capacité accrue de signalisation binaire sans interférence sensible entre les symboles.

Abstract: Procédé pour la production de copolymères d'anhydride maléique et d'un alcoyle-vinyl-éther C1-C8, qui consiste à précharger un réacteur avec une solution d'anhydride maléique dans un solvant monoéther à empêchement stérique et à y ajouter le monomère alcoyle-vinyl-éther. La copolymérisation se fait en présence d'un excitant à radical libre. La polymérisation produit dans le milieu de réaction une boue pompable du copolymère, dont on peut tirer un produit copolymère qui est essentiellement une poudre sans benzène.

Abstract: A device for mixing a fluid, for example, carbon dioxide, with a liquid, for example an aqueous beverage solution has a combining part in which one or more infusion chambers are formed within a cylinder by chamber closing plates carried on a common axially shiftable stem. The mixture is passed from chamber to chamber through diaphragm orifices in these plates and the liquid is injected through radial bores in the cylinder wall which can be controlled by collars formed on the edges of the plates. The gas is introduced into the upstream chamber through another radial port. Downstream of the combining part, the mixture flows through an in-line mixer having walls provided with turbulence inducing formations and one of which is movable with the stem.

Date Sep. 19, 1991.An adjustable temperature gas feed is available that feeds firstly the grinder and secondly pre-drying means. At the outlet from the grinder, the gas that has passed through the grinder is combined with the gas that has passed through the pre-drying means to convey the ground material. The total gas flow rate QA at the oulet lies between a minimum flow rate and a maximum flow rate, and the flow rate Q1 of the gas passing through the grinder (1) is proportional to the quantity Qc of material placed in the grinder. According to the invention, a temperature T to be reached by the gas outlet temperature is set (optionally as a function of the moisture content of the material), and the gas feed is adjusted in such a manner that the feed gas is as hot as possible with the quantity of gas passing through the pre-drying means being limited to as little as possible. The method adapts to the material having different moisture contents and improves efficiency while leading to combustion with low NOx.
