Patent CA-2218808-A1 (CA)
Title: Improved retroviral vectors, especially suitable for gene therapy
Inventor: VAN BEUSECHEM VICTOR WILLEM
IPC: C12N7/00
Filed: 1996-05-07
Abstract: The present invention relates to the field of molecular biology, especially recombinant DNA technology, especially concerning retroviral vectors. Retroviral vectors are very suitable vehicles for transferring genetic material of interest into certain cells in so-called gene therapy strategies. However, the retroviral vectors described so far are not ideal. They may give rise to recombination events resulting in helper (pathogenic) virus, they may express viral proteinaceous materials leading to immune responses, etc. These and other drawbacks are overcome by the vectors, cells, kits and methods of the present invention by providing a vector derived from a retrovirus, comprising a sequence responsible for transcriptional control, including an enhancer, which vector further comprises a site for insertion of at least one gene of interest, a packaging signal, said vector having no superfluous retroviral sequences and no open reading frame encoding at least parts of viral proteins, characterized in that the enhancer is an enhancer that is active in undifferentiated cells.

Inventor: BRENNAN PAUL MICHAEL
IPC: H04M1/663
Filed: 1997-10-30
Abstract: On receiving a new call, a controller in a telephone station apparatus compares the incoming caller information with caller information in stored records.  On a match, an associated name is spoken over a handsfree speaker and then the controller places the telephone station apparatus in a handsfree off-hook condition.  In this way, someone in a hands-busy situation or a handicapped individual may have calls from pre-selected callers automatically connected.  The controller may also store a two-way or one-way communication path indication with each record and, accordingly, establish either one-way communication path from the calling party to the telephone station apparatus or a two-way communication path to and from the telephone station apparatus.

Inventor: SCHON G STEVEN
IPC: C01D15/04
Filed: 1998-06-05
Abstract: L'invention concerne un procédé de fabrication de l'hexafluorophosphate de lithium, par réaction du pentafluorure de phosphore avec le fluorure de lithium. Le procédé selon l'invention est caractérisé par le fait que l'on met en contact, d'une part, du pentafluorure de phosphore gazeux ou un mélange gazeux comprenant du pentafluorure de phosphore et de l'acide chlorhydrique, et, d'autre part, une solution de fluorure de lithium dans l'acide fluorhydrique, dans une colonne présentant un nombre d'unités de transfert suffisant pour réaliser la réaction du PF5 avec LiF dans des conditions prédéterminées de température, de pression et de rapport molaire des deux réactifs en présence, et avec absorption totale ou sensiblement totale du PF5 au sein de la colonne. Ce procédé permet de résoudre les problèmes de bouchage en empêchant les recristallisations de sels; d'évacuer les calories dégagées par la réaction par la vaporisation d'une partie de l'HF; de séparer l'HCl éventuellement contenu dans le PF5 de départ, sans perte de PF5, ce qui autorise un traitement ultérieur de récupération/valorisation de cet HCl. Ce procédé est par ailleurs très simple, avec un nombre d'étapes minimal, ce qui permet d'éviter toute entrée d'air ou d'humidité susceptibles de polluer le LiPF6 final.

Title: Appareil et procede de deploiement de stent a greffer
Inventor: LEOPOLD ERIC
IPC: A61F2/844
Filed: 1996-12-13
Abstract: Appareil ou mécanisme (320, 322) de déploiement de stent ou de stent à greffer configuré de manière telle que lorsqu'il est activé, le stent ou stent à greffer (2) se déploie progressivement dans une direction depuis sa première extrémité, qui est placée de manière proximale par rapport à l'instrument de déploiement, tel qu'un cathéter percutané, vers son extrémité qui est placée de manière distale par rapport à l'instrument de déploiement. Le mécanisme de déploiement de stent ou de stent à greffer peut présenter une configuration (306) d'amarre ou de ligne de glissement qui peut réduire à un minimum la possibilité d'accrochage entre la ligne et l'élément de stent. Un procédé permettant de déployer un stent ou stent à greffer dans la lumière d'un mammifère, qui consiste à déployer le stent ou stent à greffer dans une direction proximale à distale, est également décrit. L'appareil et le procédé de la présente invention peuvent réduire à un minimum la possibilité de déplacement du stent ou du stent à greffer par rapport au site désiré avant qu'il soit quelque peu fixé dans le vaisseau pendant le déploiement. Le moyen de déploiement peut faciliter l'expansion dans une direction de l'aval vers l'amont, alors que le fluide dans le passage s'écoule vers l'aval.
Patent CA-2243921-A1 (CA)
Inventor: HUBER HANS
IPC: B65B13/22
Filed: 1998-07-27
Abstract: Disclosed is a band moving device of a strapping machine for applying a band around a package, which band moving device is provided with an envelope drive having only one enveloping component, which is guided, by way of an inner surface, over at least two wheels.  At least one of the two wheels is designed as a drive wheel that can be brought into operative connection with a drive motor to drive the enveloping component.  The band may be pressed onto an outer surface of the enveloping component by means of a pressure pulley in order to produce, between the band and the enveloping component, a frictional force by means of which the band can be moved in one direction.   The pressure pulley is arranged in a region in which the enveloping component wraps around one of the two wheels, thus making it possible for the enveloping component to be pressed against one of the two wheels by the pressure pulley.  There is means for reversing the direction of rotation of the enveloping component, so that the band can be moved both in a feeding direction and in a tensioning direction.  A further wheel is located opposite the outer surface of the enveloping component, and is designed as a tensioning wheel and, during a tensioning phase, presses the band onto the enveloping component in order to apply a band tension.

Title: Pressure vessels and end closures therefor
Inventor: GILBERTSON TERRY
IPC: B29C53/58
Filed: 1997-03-12
Abstract: Pressure vessels having end closures for sealing at least one open end are constructed so as to provide full-bore access to a generally tubular shell portion wherein one or more filter cartridges will be disposed.  A sealing ring (45) of rectangular cross section is seated in a groove provided in the tubular shell (15) at a location axially inward of a cylindrical surface region wherein a central annular groove is provided. A closure head (39) fits within this annular surface and includes a shoulder (73) which prevents insertion past the sealing ring (45). The head may be a 2-piece construction wherein a flanged and dished element having an inward facing convex surface of oblate spheroidal shape protrudes through the interior of the sealing ring and mates with a securing plate (41) having an annular notch in the periphery of its outer face that aligns with the groove in the tubular shell to create a pocket designed to receive a helical locking ring (79) in the form of a spring-like band of at least two revolutions that cannot be inadvertently removed when the vessel is pressurized. A bell-end configuration for the tubular shell is efficiently created from filament-reinforced polymeric resin through the use of a sacrificial insert that not only creates the seat for the sealing ring but also provides space to accommodate side flow fluid connections.
