Abstract:
La présente invention concerne un procédé de fabrication d'une poudre chargée électriquement conductrice de polymères thermoplastiques. Le procédé comporte les étapes de réalisation d'une poudre originelle (10) contenant des noyaux (3) de polymères thermoplastiques, et de réalisation de ladite poudre chargée (1) à l'aide de fils (4) submicroniques électriquement conducteurs et de cire (6), en formant une pluralité d'ensembles (2) comprenant chacun un dit noyau (3) ainsi qu'au moins un dit fil (4) et une membrane de protection (5) en ladite cire.
Abstract:
In a production process of granules containing a biologically active substance, variation in the elution profile of the biologically active substance is reduced by heating the temperature of granules to about 50°C or higher and maintaining the temperature for about 1 minute or longer. By setting the spray speed to about 90 mg/min or more per 1 g of cores when a spray agent for a primary agent containing the biologically active substance is sprayed while spraying a binding liquid to the cores and setting the total feeding weight per unit area for a centrifugal fluidized bed coating granulation machine to about 1.5 g/cm 2 or more, the variation in the elution profile of the biologically active substance from the granules is reduced.
Abstract:
The invention relates to phosphor powders and a method for making phosphor powders. The powders are oxygen-containing, such as metal oxides, borates or titanates and have a small particle size, narrow particle size distribution and are substantially spherical. The method of the invention advantageously permits the continuous production of such powders. The invention also relates to improved devices, such as display devices, incorporating those shown by the figure, incorporating the phosphor powders.

Abstract:
The invention relates to a process for the controlled production of particles comprising the steps of producing an emulsion comprising one or more compounds to be solidified in its dispersed phase, and dosing a suitable antisolvent to said emulsion, forcing the one or more compounds to solidify. Optionally, the solidified compound(s) is/are encapsulated or coated.
Abstract:
The invention provides a method for utilizing liquid wastes, especially those that are toxic and harmful an in particular those in the form of sludge, sewage, paste and liquids. In the method provided by the invention a tank in which there is negative pressure is filled up to 50% of its capacity with liquid chemical wastes in the form of paint sludge. The tank is made to move with rotary motion and the sludge inside is treated with superheated steam at 150°C until the sludge is turned into granulated material, after which sulphur polymer is injected into the tank being in continous motion. The motion of the tank and the injection of sulphur polymer are stopped after the granulated waste is completely coated with sulphur polymer. The granulated waste with sulphur polymer coating is poured into drums or moulded into construction elements.
Abstract:
A biological tissue transplant coated with a stabilized multilayer alginate coating and a method for preparation of the stabilized multilayer coating. Coating has three primary layers of the alginate with a polyamino acid barrier emplaced between a primary and a secondary layer. The secondary "halo" layer of soft gel is formed by a gel gradient created between weakly bound cross-linking gelling divalent cations of an alginate used for the primary layer of the coating and non-gelling counter ions of a non-ionic alginate of the secondary layer of the coating.
