Patent CA-2423699-A1 (CA)
Title: Hydrocarbon gas processing
Inventor: PIERCE MICHAEL C
IPC: C10G5/06
Filed: 2001-09-28
Abstract: A process for the recovery of ethane, ethylene, propane, propylene and heavier hydrocarbon components from a hydrocarbon gas stream (31) is disclosed. In recent years, the preferred method of separating a hydrocarbon gas stream (31) generally includes supplying at least portions of the gas stream (31) to a fractionation tower (17) having at least one reboiler, and often one or more side reboilers, to supply heat to the column by withdrawing and heating some of the tower liquids (40, 42) to produce stripping vapors that separate the more volatile components from the desired components. The reboiler and side reboilers (if any) are typically integrated into the feed stream cooling scheme (10) to provide at least a portion of the refrigeration needes to condense the desired components for subsequent fractionation in the distillation column (17). In the process disclosed, the tower reboiling scheme is modified to use one or more tower liquid distillation streams (40) from a point higher in the column (17) than is used in the conventional reboiling scheme, providing colder stream(s) for the reboiler(s) that allow more effective cooling of the feed streams and thereby improve the efficiency with which the desired components are recovered. In addition, the tower liquid streams (40) withdrawn from a higher point in the column (17) contain larger quantities of the more volatile components, which when vaporized provide better stripping of undesirable components like carbon dioxide without reducing the recovery of the desired components. The heated distillation stream (40a, 42a) is returned to a lower point on the fractionation tower that is separated from the withdrawal point by at least one theoretical stage.

Title: Procede de fabrication d'un article comportant une impression sur deux cotes de mise a plat et article ainsi fabrique
Inventor: STOCKLEY HENRY WALKER III
IPC: B65D33/00
Filed: 2001-10-25
Abstract: L'invention concerne un article pouvant être mis à plat constitué d'un film souple et comportant une impression sur ses deux côtés de mise à plat, cette impression étant confinée dans une zone d'impression située autour d'une première moitié de l'article imprimé, la seconde moitié dudit article ne comportant aucune impression. Un procédé de fabrication de cet article plat permet de réaliser l'impression uniquement sur un premier côté de mise à plat d'un tube souple, lequel est alors reconfiguré selon une seconde configuration de mise à plat de façon que l'impression soit réalisée sur les deux côtés de mise à plat de ce tube dans la seconde configuration de mise à plat. Ledit tube est alors converti (par coupage et éventuellement par soudure) en article d'emballage, de préférence en sac, et notamment en sac à soudure terminale ou à soudure latérale. Dans un autre mode de réalisation, un article d'emballage imprimé sans adhésif constitué d'un film souple comporte deux zones imprimées, l'une de ces zones recouvrant un premier bord latéral de l'article, l'autre recouvrant le second bord latéral dudit article. Le procédé de fabrication de cet article consiste à réaliser une impression sur les deux côtés de mise à plat initiaux d'un tube, puis à opérer une reconfiguration de façon à obtenir une seconde configuration de mise à plat dans laquelle les zones imprimées sont situées sur les bords latéraux du tube reconfiguré. L'invention concerne également des produits emballés au moyen de ces articles.

Title: Medico-surgical instruments
Inventor: GOSTELOW THOMAS
IPC: A61B17/24
Filed: 2003-08-21
Abstract: Known instruments for providing ventilation access to the trachea have a hollow needle with a sharp tip used to provide access to the trachea. In the present invention a tube extends within the needle and a spring urges the tube to project a short distance from the patient end of the needle. The rear end of the tube carries two colored flags one of which is visible at a time in a transparent window towards the machine end of the needle. When the patient end of the instrument is pushed through neck tissue overlying the trachea the inner tube is pushed rearwardly so that a flag of one color is visible. When the patient end of the instrument enters the trachea the spring can push the inner tube forwardly so that the other flag is visible. In one embodiment the instrument carries a dilator and tracheostomy tube that can be slid off the needle after penetration. In another embodiment, ventilation equipment is connected to the rear of the inner tube and the patient is ventilated through the instrument itself.
