Abstract: Technique d'encapsulation selon laquelle deux pellicules (14, 16) de matériaux semblables susceptibles de se déformer de façon élastique, du moins lorsqu'ils sont soumis à une solvatation partielle, sont amenés dans un élément d'encapsulation (22). Un solvant est appliqué sur l'une au moins des pellicules avant l'encapsulation pour produire une solvatation partielle de la surface du matériau, de façon que la surface soumise à la solvatation partielle puisse adhérer au matériau de la pellicule et s'unir à celui-ci. Dans l'élément d'encapsulation, la substance à encapsuler, par exemple une huile cosmétique ou une préparation à base de vitamines, passe entre les pellicules. On donne aux pellicules, généralement par moulage, la forme voulue de parties de gélules qui peuvent se coller l'une et l'autre en raison de l'adhérence de la ou des surfaces soumises à une solvatation partielle. Ces parties se collent ensemble en enfermant la substance fournie et forment une gélule. L'invention permet de procéder à une encapsulation en utilisant des matériaux autres que la gélatine, comme l'alcool de polyvinyle. L'invention décrit aussi un appareil d'encapsulation et les gélules résultantes.

Abstract: Hydrocarbon feedstocks are converted into synthesis gas in a two-stage process comprising an initial steam reforming step followed by final conversion to synthesis gas in a mixed conducting membrane reactor. The steam reforming step converts a portion of the methane into synthesis gas and converts essentially all of the hydrocarbons heavier than methane into methane, hydrogen, and carbon oxides. The steam reforming step produces an intermediate feed stream containing methane, hydrogen, carbon oxides, and steam which can be processed without operating problems in a mixed conducting membrane reactor. The steam reforming and mixed conducting membrane reactors can be heat-integrated for maximum operating efficiency and produce synthesis gas with compositions suitable for a variety of final products. Synthesis gas produced by the methods of the invention is further reacted to yield liquid hydrocarbon or oxygenated organic liquid products.

Granted: 2005-05-10
Abstract: The invention concerns a method for making smart cards by rolling. A first synthetic sheet (1) is first smoothed by hot pressing against a first smoothing plate (4). Likewise a second synthetic sheet (2) is smoothed against a second smoothing plate (5). Without being unstuck from their smoothing plates, these two sheets are rolled with other layers (3, 6, 7), said synthetic sheets (1, 2) serving as external layers. One of the smoothing plates may comprise a three-dimensional pattern to be relief printed on the synthetic sheet. The rolling is carried out by cold pressing the different layers (1, 6, 3, 7, 2) which the laminated card comprises between the two smoothing plates (4, 5). After being rolled, different cards with adapted dimensions can be cut out from the laminated sheets. The invention is advantageous in that the same plates (4, 5) are used for the hot pressing and the cold rolling. The external surface of the synthetic sheets (1, 2) thus remains protected between these two operations and the cards have better inherent flatness.

Title: System for extracting soluble heavy metals from liquid solutions
Inventor: PANG DAVID C
IPC: B01D15/08
Filed: 1997-11-03
Granted: 2008-02-19
Abstract: A process for removing ions of dissolved heavy metals and complex heavy metals comprises providing a treatment zone in which is contained an extraction material having an activated surface that has an affinity for heavy metal ions and complex heavy metal ions. The activated surface is the reaction product of a polyamine with a covalently anchored trifunctional hydrocarbylsilyl that yields non-crosslinked amino groups to which functional chelator groups can be covalently attached.  The activated surface of the extraction material is formed by first hydrating the extraction material surface and then silanizing the hydrated surface with a short chain trifunctional silane having a hydrocarbon substituent containing 1-6 carbon atoms and a terminal leaving group, and then reacting a polyamine with the hydrocarbylsilyl from the silanization of the hydrated surface so as to form an aminohydrocarbyl polymer covalently bound to the extraction material surface.
