Patent EP-0471278-A1 (EP)
Inventor: LIN PING-WHA
IPC: B01D53/60
Filed: 1991-08-07
Abstract: Sulfur dioxide (S0 2 ) can be oxidized to rapidly sulfur trioxide (S0 3 ) in a high temperature environment. It has been found that the S0 2  oxidation rate can be impeded by a high rate of temperature reduction in a dynamic condition such as in a boiler and the ductwork of a power plant and an industrial plant. The mechanism of the reaction kinetics has been developed. With the understanding of the mechanism, the methods for oxidation of S0 2  to form SO 3  have been developed. The SO 3  rich flue gas is treated with lime (CaO) in a fluidized lime reactor wherein SO 3  reacts with CaO to form CaS0 4  coating on the surface of CaO. The high heat generated from the S0 3 /CaO reaction causes the remaining S0 2  to convert in the reactor to SO 3  which in turn reacts with CaO to form more CaS0 4 . Nitrogen oxides can also be removed from flue gas by converting nitric oxide (NO) to nitrogen dioxide (N0 2 ) via a high time rate of temperature reduction within ductwork and by sudden cooling with a spray of fine water mist or water vapor. N0 2  reacts with water vapor to form nitric acid which in turn reacts with lime to form calcium nitrate Ca(N0 3 ) 2 . The plant gas effluent, after treatment with the improved Lin flue gas SO x /NO x  removal process, is essentially free from SO x , N0 2 , and particulate materials.

Abstract: A cased telescoped ammunition in which a rigid liner (34) fills the gap between the control tube (16) and the metering tube (22). The liner (34) comprises an energetic material which transfers the ignition stimulus from the control tube propellant (18) to the main propellant (40). Energetic materials in the liner (34) can be modified to increase the ignition stimulus for proper cold round performance or decrease ignition stimulus for an improved timed sequencing of the round's performance. Both double-based and single-based energetic materials may be used.

Abstract: Mixed oxides of zirconium and yttrium [ZrO₂(Y₂O₃)], with an yttrium content (as computed as elemental metal) comprised within the range of from about 15 to about 21% by weight, as spherical particles with size comprised within the range of from 0. 1 to 2 µ m, with an average size of the particles lower than 1 µ m, in the cubic crystal form, are obtained by:
     preparing a mixture by starting from an aqueous solution of zirconium and yttrium carboxylates; an organic solvent selected from the group consisting of nitriles or alcohols; and a non-ionic surfactant;   causing solid colloidal particles of the precursor of mixed zirconium/yttrium oxides to precipitate from said mixture, by operating at a pH value comprised within the range of from 5 to 7, at room temperature or at temperatures close to room temperature; and   calcining said precipitate of solid particles at a high temperature to cause said solid particles to be directly converted from the amorphous state into the cubic crystal form.   
     According to a particular form of practical embodiment, ultrasounds are applied to the mixture during said precipitation step, to further reduce the size of the precipitated particles. 
     The so obtained mixed oxides of zirconium and yttrium are suitable for use in the electronic sector, in particular as a solid electrolyte for fuel flow cells.

Abstract: A method for control of ethylene biosynthesis in plants comprising a vector containing a selective gene under plant promoter control, and a DNA insert comprising codons for a functional heterologous polypeptide having AdoMetase activity and flanked by a plant promoter on one side and a polyA signal sequence on the other side; and, transforming a plant host with said vector wherein the plant host transformed thereby is capable of expressing the heterologous polypeptide having AdoMetase activity under the control of said control region. The presence and expression of AdoMetase in transgenic plants lowers AdoMet levels and generates an inhibitor of ACC synthase causing a corresponding decrease in ethylene biosynthesis and precursor availability. The current construction of transgenic plants containing a copy(s) of the T3 AdoMetase gene allow for construction of plants that will control ethylene biosynthesis resulting in fruits, vegetables, and flowers which have improved shelf life and preservation qualities.

Abstract: Un processeur ultra-rapide utilise une logique combinatoire et une limitation de plage pour une valeur d'entrée modifiée, en vue d'augmenter l'efficacité de la détermination du facteur de convergence pour la division convergente et la calcul de la racine carrée. Une valeur d'entrée (101) est modifiée pour obtenir une certaine valeur dans une plage limitée (104), qui est ensuite divisée en deux subdivisions (106, 108). A l'aide de ces deux groupements, le programme de traitement réduit au minimum le temps nécessaire pour déterminer le facteur de conversion en inversant les bits binaires sélectionnés pour former un facteur modifié (114), et le programme utilise ensuite ce facteur modifié pour faciliter le calcul ultra-rapide du facteur de convergence.

Abstract: Les revêtements lubrifiants hydrophiles de cette invention sont beaucoup plus lubrifiants lorsqu'ils sont humides que lorsqu'ils sont secs, ils adhèrent sur plusieurs types de substrats et résistent au détachement par voie humide. Dans un mode d'exécution, les revêtements comprennent une polyoléfine hydrophile telle que de la polyvinylpyrrolidone et un polymère stabilisateur insoluble dans l'eau tel qu'un ester de cellulose. Les revêtements peuvent également comporter un polymère adhérent et un agent plastifiant. On peut appliquer le revêtement en préparant une solution du polymère stabilisateur et une solution de la polyoléfine hydrophile, puis en couchant le substrat dans la première solution puis dans la deuxième solution. On peut également dissoudre les polymères hydrophiles et de stabilisation dans un système à solvant unique, qu'on applique ensuite sur le substrat en une seule fois. Dans un autre mode d'exécution, on applique directement sur le substrat une seule solution d'une polyoléfine hydrophile. Dans ce mode d'exécution, la solution de polyoléfine hydrophile renferme un cosolvant faisant office de solvant pour la polyoléfine hydrophile et le substrat. On peut appliquer les revêtements de cette invention sur des dispositifs et des implants biomédicaux, tels que des cathéters, des préservatifs, et des tuyaux naso-gastriques et endotrachéaux.
