Abstract: Dans la production de naphtalate de polyéthylène selon la présente invention, la réaction d'estérification entre l'acide naphtalènedicarboxylique et l'éthylèneglycol est exécutée en présence d'eau dès le début dans un système de réaction et en présence d'au moins un catalyseur choisi dans le groupe constitué par des sels et des amines azotiques, carboxyliques, phosphoriques et hydrophosphoriques en fonction des nécessités pour atteindre ainsi un taux d'estérification de 45 à 80 %, de telle sorte que l'on obtient un mélange liquide de produits de réaction de l'estérification de l'acide naphtalènedicarboxylique, qui comportent cet acide, du carboxylhydroxyéthoxycarbonylnaphtalène et du bis(hydroxyéthoxycarbonyl)naphtalène. Ensuite, on sépare un cristal de ce mélange liquide pour obtenir un mélange de produits de réaction de l'estérification. Après cela, on ajoute à ce mélange de l'éthylèneglycol en fonction des besoins et on lui fait subir une polycondensation. Le naphtalate de polyéthylène obtenu avec le procédé selon la demande assure une faible teneur en esters d'acide naphtalènedicarboxylique, chacun d'eux comportant un squelette de diéthylèneglycol, ce qui leur confère une excellente qualité, par exemple, en ce qui concerne leur aspect.

Patent CA-2217987-A1 (CA)
Inventor: SIEGLE SVEN
IPC: C08H7/00
Filed: 1996-05-02
Abstract: L'invention concerne un procédé de production de pulpe d'un matériau cellulosique, selon lequel le matériau est mélangé à de l'acide formique servant de solvant, et est porté à ébullition approximativement à la température d'ébullition du solvant, avec refroidissement au reflux. Les matériaux cellulosiques appropriés peuvent être des plantes annuelles, des bois feuillus ou des bois conifères. Dans une variante dudit procédé, le matériau cellulosique n'est chauffé que légèrement avec refroidissement au reflux, puis on y ajoute ensuite lentement et sensiblement, sans apport énergétique externe supplémentaire, un volume déterminé avec exactitude au préalable de peroxyde d'hydrogène, en dosage constant. Cette variante du procédé peut être répétée avec une diminution de la température de traitement. La pulpe ainsi obtenue sert de préférence à produire de la cellulose, notamment dans le cadre de la fabrication de papier ou de carton. Selon l'invention, la lignine dissoute hors du matériau cellulosique peut être utilisée ultérieurement et isolée par précipitation dans l'eau après que la pulpe ait été séparée du solvant. La lignine ainsi obtenue s'utilise comme nouveau matériau de construction, comme charge ou comme produit de départ pour produire des substances aromatiques.

Upon selective cleavage of the cleavable site, primer extension products that contain about five or fewer base pairs of the primer sequence are released, to provide more useful sizing and sequence information per fragment than extension products containing the entire primer.
Patent CA-2221376-A1 (CA)
Inventor: SCHNELL JAMES H
IPC: F24J3/08
Filed: 1996-06-07
Abstract: Ce système (10) de production d'électricité à partir de l'énergie géothermique repose sur l'utilisation de réactions endothermiques au fond d'un puits (12) pour capter et stocker la chaleur géothermique, ainsi que sur des réactions exothermiques au sommet de ce puits (12) pour libérer la chaleur stockée dans les produits des réactions endothermiques. Selon un mode de réalisation préféré, la décomposition de l'eau constitue la réaction endothermique. Pour induire cette réaction endothermique et récupérer et séparer les produits résultants, on utilise un dispositif catalytique (22) dans lequel chaque type de produit diffuse sélectivement dans sa propre conduite (24, 26). Les produits endothermiques subissent la réaction exothermique dans une turbine à combustion (240), et les produits de cette réaction exothermique sont immédiatement condensés dans un condenseur (242). Selon un mode de réalisation préféré, ce condenseur (242) condense la vapeur en eau, laquelle est renvoyée vers le bas du puits (12), ce qui crée un système fermé.

Patent CA-2224731-A1 (CA)
Inventor: LEWIS KEITH LODER
IPC: G07D7/00
Filed: 1996-06-19
Abstract: A covert method of distinguishing between genuine and counterfeit articles by means of applying an optical filter to genuine articles as a mark of authenticity. The filter for use in the method may comprise a multi layer stack having at least one maximum and at least one minimum in the spectral characteristic and a selective absorber over a range of visible wavelengths.  The spectral characteristic is such that the filter has a neutral appearance when viewed by an unaided eye under normal lighting conditions, but gives rise to characteristic optical effects when illuminated with selected wavelengths.  The characteristic effects provide an authenticating signature for the filter.  In the absence of the filter, the illumination would not give rise to the characteristic effects. The intensity of radiation reflected or transmitted by the filter at two or more wavelengths may be used to provide the authenticating characteristic. In an alternative embodiment, the filter may be illuminated with radiation at two or more angles of incidence. The resulting intensity or spatial distribution of radiation reflected or transmitted by the filter may be used to verify the authenticity of the article by comparing the observed properties with known properties for the filter.
