Patent CA-2149528-A1 (CA)
Inventor: YORK BILLIE M
IPC: A61P27/06
Filed: 1994-09-29
Abstract: L'invention porte sur l'emploi de mélanges de stimulateurs de croissance de cellules du stroma (p. ex. TGF-.beta.) et d'antimétabolites (p. ex. la mitimycine C) en relation avec la chirurgie du glaucome par filtration qui s'appliquent sur le site opératoire pour attirer, activer mitogéniquement, et neutraliser la synthèse de matrices extracellulaires induisant la formation de cicatrices par les cellules du stroma. En l'absence de ce traitement, la formation de tissus cicatriciels peut occasionner l'arrêt du flot efférent d'humeur aqueuse sur le site opératoire, surtout au niveau de la fistule. L'activation mitogène des cellules du stroma a pour effet de les rendre sensibles aux antimétabollites lesquels sont alors en mesure de supprimer la prolifération des fibroblastes et autres cellules du stroma associées dans une proportion nettement plus élevée que lorsqu'on utilise les métabolites seuls. Cette limitation accrue de la prolifération et du métabolisme de ces cellules se traduit par une amélioration significative de la capacité à prévenir ou retarder la formation de tissus cicatriciels, et de ce fait par un moindre nombre de fermetures de fistules suite à des opérations du glaucome par filtration.

Title: Continuous mixing of silica loaded elastomeric compounds
Inventor: ESWARAN VETKAV RAJAGOPALAN
IPC: B29C48/405
Filed: 1996-01-29
Abstract: A method of making silica loaded elastomer masterbatches or compounded productive elastomer stocks with or without the simultaneous extrusion of component profiles is provided.  A twin-screw extruder is used to mix the elastomeric stock in multiple mixing zones at controlled temperatures in which a concurrent chemical reaction takes place between the silica coupler, the silica, and/or the diene based elastomer.  Silica, elastomer, silica coupler, and other ingredients are fed into the twin screw extruder continuously through precise loss-in-weight or volumetric feeders.  Chemical reactions(s) in the elastomer/silica based composition take place within the twin-screw extruder while the composition is mixing.  The product is forced through a profile die mounted at the exit of the extruder and formed into the shape of the desired component.  The maximum rate of mixing tends to be a function of the heat transfer efficiency, the conveying capacity of the screws, and the mechanical strength of the extruder.
