Patent CA-2389277-A1 (CA)
Title: Solar energy concentrator and converter
Inventor: ARKAS NICHOLAS
IPC: H01L31/054
Filed: 1999-11-11
Abstract: A solar energy concentrator (1) is formed in the shape of a spiral horn, so that solar energy incident over a wide range of incident angles on the mouth (2) of the horn is concentrated by multiple reflections from inner walls (5) of the horn to emerge from an exit aperture (3) at the centre of the horn. Solar energy emerging from the collector may be distributed by light pipes (40) to illuminate a building or may be transmitted to a solar energy conversion chamber (50) having a small entry aperture (51). The entry aperture (51) acts as black body absorbing all solar energy incident upon it and the solar energy may be converted within the chamber (50) either by photovoltaic cells and/or by heat absorbing media.

Title: Process for blending a difficultly soluble pharmaceutical substance with a solvent using a syringe for applying the process
Inventor: OTTO THOMAS
IPC: A61J1/05
Filed: 2002-08-13
Abstract: The process serves to blend a difficultly soluble pharmaceutical substance filled preferably in the front chamber (2) on the cannula side of the syringe barrel (3) of a dual- chamber syringe (1) with a solvent filled in the second chamber (4). Both chambers (2, 4) are separated from one another by a central stopper (8). By displacing the stopper (6) located at the plunger rod (5), first the central stopper (8) is displaced into the area of a by-pass (9) arranged in the wall of the syringe barrel (3) where it is stopped by lock stops (10). The solvent is then transferred via the by-pass (9) into the front chamber (2), which is sealed off by a closure system (11) arranged on the cannula side, thereby building up pressure in this chamber (2). Finally, the stopper (6) is pushed out by the built up pressure so that a portion of the solution together with a portion of the pharmaceutical substance flows back into the rear chamber (4) via the by-pass (9).

Abstract: L'invention concerne un procédé permettant de mettre en évidence la présence de 5-méthylcytosine dans des échantillons d'ADN génomiques. Dans un premier temps, un ADN génomique issu d'un échantillon d'ADN est mis à réagir chimiquement avec un réactif, la 5-méthylcytosine et la cytosine réagissant différemment. L'ADN prétraité est ensuite amplifié à l'aide d'au moins une polymérase et d'au moins une amorce. A l'étape suivante, l'ADN génomique est amplifié est hybridé sur au moins un oligonucléotide de manière à former une double hélice, celui-ci étant prolongé d'au moins un nucléotide. Ledit nucléotide porte un repère identifiable et la prolongation dépend du statut de méthylation de chaque cytosine dans l'échantillon d'ADN génomique. A l'étape suivante, les oligonucléotides prolongés sont examinés afin d'identifier la présence du repère.
