Patent CA-2379348-C (CA)
Inventor: PODREBARAC GARY G
IPC: B01D3/16

Granted: 2009-04-28
Abstract: L'invention concerne un procédé de séparation d'isobutène de haute pureté, normalement inséparable du butène-1 par fractionnement, à partir de butènes contenus dans un flux d'hydrocarbures mélangé contenant du butène-1, du butène 2 et de petites quantités de butadiène, dans lequel le flux d'hydrocarbures mélangé (107) est distribué à un réacteur de colonne de distillation (40) contenant un catalyseur d'oxyde de palladium ayant pour support de l'alumine. Ladite colonne a tendance à empêcher le butène-2 d'entrer en contact avec le catalyseur et à maintenir le butène-1 en contact avec le catalyseur, afin d'isomériser le butène-1 au butène-2. Une fois produit, le butène-2 est distillé sans le catalyseur, par inversion de l'équilibre, ce qui permet de produire des quantités de butène-2 supérieures aux quantités d'équilibre. L'isobutène et l'isobutane sont séparés simultanément du butène-2. En outre, tous les butadiènes de l'alimentation sont hydrogénés aux butènes. Le résidu (108) est riche en butène-2.

Patent CA-2397576-C (CA)
Inventor: HARKLESS CURT
IPC: G06K9/00
Filed: 2002-08-12
Granted: 2013-02-12
Abstract: An approach for the compression of images such as fingerprints may involve a resolution reduction of an image before forming a cellular representation of the resulting resolution-reduced image. A given fingerprint image is divided into a number of finger pattern cells. Each finger pattern cell is then compared to each finger pattern cell in a set of predetermined finger pattern cells to find a close match. The set of closely matching predetermined finger pattern cells forms the cellular representation. The cellular representation may then be used as a basis for a finger pattern interchange data format for use with pattern-based fingerprint matching algorithms. The finger pattern interchange data comprises an identification of the predetermined finger pattern cells that most closely approximate the finger pattern cells that make up the fingerprint image.
