Inventor: BREITENBACH JOERG
IPC: A61K9/16
Filed: 1999-10-14
Abstract: A method for producing solid, spherical materials containing at least one biologically active substance that is homogeneously dispersed in an auxiliary agent template by mixing said biologically active substance with one or several auxiliary agents in a melt, extruding and shaping said melt using a nozzle, characterized in that the melt containing the biologically active substance and auxiliary agents is discharged from the nozzle in the form of drops by exciting the nozzle with vibrations and the drops are frozen and solidified by coming into contact with a liquid.
Patent WO-2004009234-B1 (WO)
Inventor: AVILA GARCIA PEDRO
IPC: B01J37/00
Filed: 2003-07-07
Abstract: L'invention concerne un procédé d'élaboration de monolithes de zéolithes naturelles ou synthétiques utilisant, comme additifs, d'autres silicates qui apportent des propriétés rhéologiques permettant un moulage par extrusion de structures en nid d'abeilles. Les propriétés mécaniques des monolithes ainsi obtenus sont stabilisées au moyen d'un traitement hydrothermal faisant intervenir des solutions de silicate de sodium. Le produit ainsi obtenu est un monolithe de type nid d'abeilles qui laisse les propriétés physiques et chimiques de la zéolithe contenue pratiquement inaltérées, ce qui permet d'utiliser ledit monolithe comme catalyseur, adsorbant ou échangeur ionique dans des processus industriels de dépuration de fluides. Les monolithes ainsi obtenus comblent les déficiences d'autres monolithes stabilisés par des traitements thermiques qui peuvent endommager sensiblement les propriétés de la zéolithe, limitant leur efficacité dans des processus de dépuration de fluides.

Abstract: The invention concerns a method for continuously coating at least one substrate B with a film of organic or mineral formulation in solution or dispersion, the viscosity of said formulation ranging between 0.001 and 100 Pa's at room temperature. Said method comprises the following steps: continuously unwinding the substrate B; driving in rotation a ductor roller with deformable surface; forming a uniform primary layer of controlled width and thickness of said formulation on the ductor roller; transferring all or part of said primary layer on an applicator cylinder with shape-retaining surface to form an intermediate layer, said applicator cylinder being located between the ductor roller and the substrate B and driven in rotation in the direction opposite to the unwinding direction of the substrate B; and transferring the whole thickness of the intermediate layer, from the applicator cylinder onto the substrate B while pressing the applicator cylinder against the substrate B to obtain a coating film with homogeneous thickness. The invention also concerns the device for implementing said method.
