Abstract: The present invention provides a method and apparatus for reducing uneven brightness in an image from a particle based image system. This uneven brightness is most often seen as regions of shadow, but may also be seen as regions of over brightness. In cases where the uneven brightness is in the form of shadowing, the method corrects for the shadowy regions by first identifying the area of shadow, obtaining brightness information from a region near the shadow, where the brightness is optimal, applying statistical methods to determine the measured brightness as a regression function of the optimal brightness, and number and proximity of shadowy objects, then correcting the shadow area brightness by calculating the inverse of the function of the shadow brightness. With this method, the brightness within the shadowy or over brightness regions are corrected to appear at a substantially similar level of brightness as the region of optimal brightness in the image.

Lorsque le bouchon est fermé, le recouvrement est fixé directement sur le bouchon. Si une force ascendante est appliquée ne serait-ce que sur la languette de tirage, la première partie extrémité du recouvrement se soulève mais la base solide du bouchon reste fixée au récipient. Si une force ascendante est appliquée sur la languette de tirage et que, simultanément, une force suffisante est appliquée vers l'intérieur sur les côtés opposés du recouvrement afin de venir en contact avec la jupe tubulaire du bouchon et de la fixer, alors la base solide du bouchon se soulève simultanément, ainsi que la première partie extrémité du recouvrement, ce qui entraîne l'ouverture du récipient. Dans un deuxième mode de réalisation, le récipient et l'ensemble bouchon comportent une partie coulissante située dans le bouchon. Cette partie coulissante peut être fournie séparément du récipient et de l'ensemble bouchon, ce qui permet à l'utilisateur de former ou non un bouchon doté d'une sécurité enfants. Dans le mode de réalisation prévoyant la sécurité enfants, la partie coulissante est disposée à l'intérieur du bouchon, au moins une partie de cette partie coulissante faisant saillie hors du bouchon, à un endroit situé à proximité de la charnière. Pour ouvrir le bouchon, l'utilisateur doit exercer une force suffisante sur la partie coulissante, la pousser en l'éloignant de la charnière, de sorte qu'au moins une partie de cette partie coulissante fasse saillie hors de la partie du bouchon disposée sensiblement face à la charnière. L'utilisateur doit ensuite exercer une deuxième force suffisante vers le haut pour ouvrir le bouchon.

Abstract: A system and method for the conversion of free fatty acids to glycerides and the subsequent conversion of glycerides to glycerin and biodiesel includes the transesterification of a glyceride stream with an alcohol. The fatty acid alkyl esters are separated from the glycerin to produce a first liquid phase containing a fatty acid alkyl ester rich (concentrated) stream and a second liquid phase containing a glycerin rich (concentrated) stream. The fatty acid alkyl ester rich stream is then subjected to distillation, preferably reactive distillation, wherein the stream undergoes both physical separation and chemical reaction. The fatty acid alkyl ester rich stream is then purified to produce a purified biodiesel product and a glyceride rich residue stream. Biodiesel may be further recovered from the glyceride rich residue stream, by further separation of and/or processing of glycerides/free fatty acids contained therein. The glycerin rich second liquid phase stream may further be purified to produce a purified glycerin product and a (second) wet alcohol stream. Neutralization of the alkaline stream, formed during the alkali-catalyzed transesterification process, may proceed by the addition of a mineral or an organic acid.
