Patent CA-2516811-C (CA)
Title: Improved process for isolation and purification of paclitaxel from natural sources
Inventor: BUI-KHAC TRUNG
IPC: C07D305/14
Filed: 2004-01-27
Granted: 2009-04-14
Abstract: Disclosed is a process for the extraction and purification of Paclitaxel from a natural source of taxanes containing Paclitaxel, which comprises the steps of: a) washing with deionized or pure water, a raw material comprising Paclitaxel, this raw material coming from a natural source of taxanes, such a washing allowing removal of soluble impurities from the raw material; b) extracting with an organic solvent from the washed raw material, a wet raw material comprising Paclitaxel; c) contacting the wet raw material with a salt to obtain a biomass by precipitation, and isolating and drying the biomass; d) removing resin and natural pigments from the so isolated and dried biomass by dissolving the biomass in acetone or an acetone-hexane mixture and then adding thereto at least one-polar solvent until a Paclitaxel-~enriched oil phase is obtained; e) purifying by chromatography at least once the Paclitaxel-enriched oily phase obtained in the preceding step in a volatile solvent to obtain a purified solution and crystallization at least once the purified solution obtained by chromatography. This process advantageously permits to reduce the impurities and the volume of the Paclitaxel and analogs extract which are obtained from the biomass by precipitation, to reduce the steps of purification, to increase the amount of Paclitaxel that is obtained; and to reduce the production cost to a more economical level.

Title: Dispositif et procede de dilaceration de materiaux
Inventor: GRAHAM JAMES B
IPC: B02C19/06
Filed: 2004-06-22
Granted: 2010-02-02
Abstract: La présente invention concerne un dispositif de dilacération pouvant générer une vitesse de choc supérieure à 200 ft/s, par exemple 1.500 ft/s, qui consomme moins d'énergie que les dispositifs de dilacération classiques, d'où une plus grande efficacité que ces derniers. Le dispositif de dilacération de l'invention comprend: un volant de lancement qui crée dans les particules de matériau une force centrifuge et tangentielle pouvant accélérer les particules et leur imprimer une vitesse de choc désirée; un rotor d'impact qui présente une surface d'impact pouvant fragmenter les particules lorsque celles-ci heurtent la surface d'impact; et un moteur qui alimente le rotor d'impact et le volant de lancement. Pour augmenter la vitesse de choc de la particule, la surface d'impact est déplacée vers la particule au moment où celle-ci quitte le volant de lancement. Ainsi, le dispositif de dilacération peut générer des vitesses de choc supérieures aux vitesses de choc produites par les dispositifs de dilacération classiques, et donc réduire en une seule passe une particule en morceaux plus petits.
Patent CA-2533621-C (CA)
Inventor: SEVICK-MURACA EVA M

Granted: 2013-12-10
Abstract: According to one embodiment of the invention, a method for biomedical imaging includes directing time-varying excitation light at a surface area of a light scattering material, the material comprising a fluorescent target. Time-varying emission light from the fluorescent target is detected, substantially at a two~dimensional sensor surface, in response to the time-varying excitation light stimulating the fluorescent target. The time-varying emission light is filtered to reject excitation light re-emitted from the material. A three-dimensional image of the fluorescent target is generated based on the detection substantially at the sensor surface.

Title: Systeme d'amorcage automatique
Inventor: DEDERING DANIEL E
IPC: F02M1/08
Filed: 2006-02-16
Granted: 2008-08-05
Abstract: Un système d'amorçage automatique pour les moteurs à combustion interne utilisable pour amorcer le carburateur du moteur à des régimes de rotation et qui est automatiquement désactivé après le démarrage du moteur. Le système d'amorçage automatique est entraîné par les fluctuations de pression dans le carter du moteur causées par le mouvement alternatif du piston. Aux régimes de rotation du moteur, une communication fluide des impulsions de pression positive et négative entre le carter du moteur et l'accumulateur est permise par un restricteur. Les impulsions de pression négative et positive sont utilisées pour entraîner la pompe à air, telle qu'une pompe à air à membrane pour pomper l'air atmosphérique dans le carburateur afin de pressuriser la cuve à flotteur du carburateur pour l'amorçage. Après le démarrage du moteur et que le mouvement alternatif du piston devienne plus rapide, le restricteur coupe la communication des impulsions de pression négative et positive entre le carter du moteur et l'accumulateur, et la pression dans l'accumulateur devient relativement constante et au-dessous de la pression atmosphérique. De cette manière, la pompe à air n'est plus entraînée par les impulsions de pression négative et positive et l'opération d'amorçage s'arrête.

Title: Gas seal structure
Inventor: ISHII SEIJI
IPC: F16J15/00
Filed: 2004-10-14
Granted: 2009-10-06
Abstract: A resin sub-seal member (11) provided with a concave groove (16) is disposed at a region closer to a higher-pressure side region than a rubber main seal member (10) and pressure variation in a gas on a higher-pressure side is inhibited from being transmitted to the main seal member (10). Further, a variation reducing space (13) is formed between the seal members (10) and (11) to be able to reduce the pressure variation when gas leakage in the sub-seal member (11) occurs or the sub-seal member (11) responds with a delay with respect to the pressure variation. Thus, rapid change in the pressure of the gas surrounding the main seal member (10) is inhibited, occurrence of the blistering phenomenon is inhibited, and a high seal ability is achieved. The seal structure is formed by a simple structure including the seal members (10) and (11), and the variation reducing space (13).

Abstract: The variable ties are used in the civil engineering for the formation of the A/B wall of variable thicknesses made of insulation plates: three types of male and female ties are used for straight A/B walls, angles of 90~ and 135~, and for the cross tie for the T-shape of the A/B wall of variable thickness.  They are made of PP-Vestolen. The variable ties serve as holders of the insulation boarding (20), carriers with the mounting distancing members (23), or carriers of plaster plates (27). Fastening is accomplished by means of lateral teeth on the neck of the male tie (24) and the lateral fixing elements on the female tie (25), (30) and (35); on the narrower part of the neck of the male tie there are the measures of the wall thickness (26). The insulation lining and the tie-lining are used for the formation of the ribbed light A/B  plate. The ties-linings connect the insulation linings in one whole, they distance the mounting (42) in the ribs of the carriers of the A/B plates (43), the ties-linings remain anchored (48) in the A/B plate, and the plaster plates are fastened to it (27).
