Title: Process for producing filled polyurethane elastomers
Inventor: COLBY SCOTT A
IPC: C08G18/16
Filed: 1998-09-23
Abstract: This invention relates to a process for producing filled polyurethane elastomers, and more particularly to a process for producing highly filled polyurethane elastomers in which resin solid separation is substantially reduced. The separation rate of the solid particulate fillers contained in a filled polyol resin is significantly reduced, and the subject process can be optimized to lower the viscosity of the uncured liquid reaction mixture prior to curing same to form a solid, thereby substantially non-cellular filled polyurethane elastomer. The above-described benefits can be accomplished by reacting together a three-component polyurethane system comprising (a) a filled polyether polyol resin having a particulate filler material dispersed therein, (b) a polyisocyanate, and (c) a catalyst solution for reacting (a) and (b) to form said filled polyurethane elastomer.

Patent CA-2252366-A1 (CA)
Title: Enhancement of gene expression
Inventor: DRAKE CAROLINE RACHEL
IPC: A01H1/00
Filed: 1997-05-23
Abstract: A method for enhancing the expression of a selected gene in an organism while avoiding or reducing co-suppression involves the synthesis of a DNA which is altered in nucleotide sequence and is capable of expression of a protein, ideally identical to that of a protein already expressed by a DNA already present in the organism. This method ensures that sequence similarity between the two genes is reduced enough to eliminate the phenomenon of co-suppression, allowing the over-expression of a specific protein. The method is particularly suitable in plants.

Title: Procede et appareil utilises pour assurer un ecoulement tourbillonnaire dans un tuyau collecteur
Inventor: DOLLAR RONALD EDDIE
IPC: E03F5/10
Filed: 1997-09-17
Abstract: Un tuyau collecteur (41-2) fournit un passage allongé dans lequel des résidus liquides et des boues (résidus) circulent suivant un trajet (598) tangentiel par rapport à au moins la surface interne du conduit. Lorsque le tuyau (41-2) présente une surface interne de section circulaire, les résidus entrants pénètrent dans le conduit (41-2) en suivant un trajet (598) tangentiel par rapport à la surface circulaire. Afin d'assurer un meilleur écoulement axial des résidus dans le conduit, jusqu'à une sortie (49), le passage permet un écoulement tangentiel (598) et forme un angle aigu (61) avec l'axe longitudinal (43) du conduit (41-2). Les résidus ayant pénétré dans le tuyau collecteur (41-2) sont poussés par les résidus récemment arrivés et continuent à s'écouler de manière hélicoïdale (59) dans le tuyau. Des passages (51-2, 51-2N) sont prévus selon un certain espacement, le long du tuyau (41-2), de sorte que la boue soit enlevée du bassin de sédimentation-clarification (non représenté). L'orientation tangentielle de chaque passage (51-2, 51-2N) renforce l'écoulement hélicoïdal existant (59P) des résidus dans le tuyau.

Title: Double layer cathode for molten carbonate fuel cells and method for producing the same
Inventor: ROHLAND BERND
IPC: H01M4/88
Filed: 1998-05-19
Abstract: The invention relates to a double layer cathode for molten carbonate fuel cells, containing a first layer (2a) consisting of a first cathode material, preferably lithium-treated nickel oxide, and a second layer (2b) consisting of cerium-activated lithium cobaltite. The inventive double layer cathode is characterised in that the polarization resistance is less dependent on temperature and in that it has a longer life. The double layer cathode is especially suitable for operating a fuel cell at less than 650 ~C. The material for the second cathode layer (2b) is produced by activating cobalt oxide by co-precipitation with cerium and treating it with lithium carbonate to form a suspension. Said suspension is then applied to the first cathode layer (2a) as a second cathode layer (2b), dried and sintered at a high temperature.
