Patent CA-2351423-A1 (CA)
Inventor: HUDSON HANK M
IPC: F25J3/02
Filed: 1999-11-24
Abstract: A process for the recovery of ethane, ethylene, propane, propylene and heavier hydrocarbon components from a hydrocarbon gas stream is disclosed. In recent years, the preferred method of separating a hydrocarbon gas stream generally includes supplying at least portions of the gas stream to a fractionation tower 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 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 to provide at least a portion of the refrigeration needed to condense the desired components for subsequent fractionation in the distillation column. In the process disclosed, the tower reboiling scheme is modified to use one or more tower liquid distillation streams from a point higher in the column 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 In addition, the tower liquid streams withdrawn from a higher point in the column contain larger quantities of the more volatile components, which when vaporized provide better stripping of undesirable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 is returned to a lower point on the fractionation tower that is separated from the withdrawal point by at least one theoretical stage.

Title: The use of 4-h-1-benzopyran-4-one derivatives as inhibitors of smooth muscle cell proliferation
Inventor: DUMONT JENNIFER A
IPC: A61P21/00
Filed: 2000-01-18
Abstract: Smooth muscle cell (SMC) proliferation is a critical component of neointimal formation in many animal models of vascular injury, and in many human lesions as well. Cell cycle inhibition by gene transfer techniques can block SMC proliferation and lesion formation in many animal models, although these methods are not yet applicable to the treatment of human disease.  Flavopiridol is a recently identified, potent, orally available cyclin-dependent kinase inhibitor. Given the role of smooth muscle cell (SMC) proliferation in vascular disease, we tested the effects of flavopiridol, a recently identified cylin-dependent kinase inhibitor, on SMC growth in vitro and in vivo.  Flavopiridol (75 nmol/L) potently blocked SMC proliferation, an effect that was associated with downregulation of cyclin-dependent kinase activity and cell cycle-related gene expression. We examined the effects of flavopiridol on SMC proliferation in vivo in the rat carotid injury model. Flavopiridol (5 mg/kg) decreased neointimal size by 35% and 39% at 7 and 14 days, respectively, after balloon injury. Flavopiridol may be a potential therapeutic tool in the treatment of SMC-rich vascular lesions. 4-H-1-benzopyran-4-one derivatives inhibit smooth muscle cell proliferation at low dosage levels.

Title: Method and device for the gathering of flat articles
Inventor: STUDER BEAT
IPC: B65H39/06
Filed: 2001-12-14
Abstract: Flat articles (5) are gathered into stacks (9) by conveying stacks in production successively along a gathering route (1) past feed stations and by adding one article to each stack in every feed station. The stacks (9) in production are conveyed on stack supports (2) with supporting surfaces (7). The supply direction of the articles comprises a component parallel to the stack conveyance direction and the supporting surfaces (7) are advantageously arranged not in parallel to the gathering route (1). The articles (5), each respectively gripped by a holding element (4) on one of their edges (5.1), are conveyed along a supply route (3) to the feed station.  The supply route (3) traverses the gathering route (1) at the feed station. The articles (5) are inserted between successive stacks (9) or stack supports (2) respectively e.g. from above with their leading edges (5.1) held gripped. The gripped edge is released from being held by deactivation of the holding element (4), when it has reached the lower zone of the stack supports (2). The released article is then positioned on the upstream or downstream stack (9) or stack support (2) by the force of gravity and/or by its own inertia and the holding element (4) is conveyed onwards in downward direction. A gathering operation of this kind is e.g. suitable for establishing dispatch units made up of different printed products. It allows very compact gathering arrangements, which, with reasonable conveying speeds, allow gathering with high performance capacities.  Furthermore, gathering of articles with very different formats is possible without any problems.
