Abstract: The invention provides for a method of depressurizing a blocked pipeline at a producing well site. The invention permits depressurization in a vapour-tight manner and facilitates the disposal of any fluids and lethal gases present. In accordance with this method, there is provided a portable vapour-tight depressurizing apparatus with a pressure vessel and flare stack for incinerating gases, all mounted on a portable trailer. The pressure vessel is connected to the pipeline by means of a flow line at the blow down point. Incoming fluids are directed to the vessel where the pressurized fluid separates into liquid and gaseous phases.  The fluids are removed from the vessel through a liquid outlet. The gas is removed through a gas outlet. The gas outlet leads to flare stack where the gas is incinerated. Fluid and gas flow is regulated by a number of sensors and control valves.

Title: System and method of completing calls to busy mobile subscribers in a radio telecommunications network
Inventor: NGUYEN VIET
IPC: H04W4/16
Filed: 1998-06-30
Abstract: A method and system of completing calls to busy mobile subscribers in a radio telecommunications network. The system includes a gateway mobile switching center (G-MSC) to provide switching functions to a mobile station (MS) in a home service area, a home location register (HLR) providing a location of the MS to the G-MSC, a visitor mobile switching center (V-MSC) to provide switching functions to the MS when the MS roams outside the home service area, and a service control point (SCP) which includes service logic for periodically initiating a call attempt to the MS to determine if the MS is busy. When the calling party attempts to call a busy MS, the calling party may request an automatic callback service. The G-MSC releases all trunks from the calling party and the MS and notifies the SCP. The SCP periodically initiates a call attempt to ascertain whether the MS is idle.  Upon determining that the MS is idle, the G-MSC connects the call between the calling party and the MS.

Inventor: MYERS DALE BRUCE
IPC: H01R24/52
Filed: 2000-02-02
Abstract: A DIN press-fit coaxial connector having a press-fit center pin and a modified BNC coaxial connector having a hollow center pin are mounted back-to-back on opposite sides of a backplane with the respective center pins of the two coaxial connectors aligned along the same linear axis and in conductive press-fit engagement with each other within a waveguide defined by a conductive-material-coated center hole in the backplane. The diameter of the center hole is dimensioned in relation to the outside diameter of a cylindrical hollow portion of the center pin of the modified BNC coaxial connector to impedance match the connection between the modified BNC coaxial connector and the DIN press-fit coaxial connector. The center hole in the backplane is empty and thereby has the dielectric constant of air, which enables the diameter of the center hole to be small enough that first and second sets of apertures can be disposed in the backplane outside the boundary of the center hole for receiving the respective sets of mounting pins of the DIN press-fit coaxial connector and the modified BNC coaxial connector.

Patent CA-2304778-A1 (CA)
Title: Rapid drying oven and methods for providing rapid drying of multiple samples
Inventor: KIESELBACH PETER
IPC: F26B9/06
Filed: 1998-10-05
Abstract: A dryer (10) for use with chemical compounds employs controlled vacuum, elevated temperature, and dry inert gas to dry the chemical compounds. The dryer includes a vacuum chamber into which trays (20) containing compounds are placed. The chamber includes heating elements which elevate the temperature of chemical samples placed within the chamber. Supplying and evacuating manifolds (24) each with a plurality of orifices for supplying, and evacuating dry inert gas, provide a substantially laminar flow of dry inert gas just above the trays of chemical compounds which are to be dried. The laminar gas flow removes the unwanted vapor which tends to form above the tray of chemical compound, thus accelerating the drying process.

Title: Verre ophtalmique plat synthetise a partir de ses specifications
Inventor: THIEBERGER GIL
IPC: G02C7/02
Filed: 1998-09-27
Abstract: L'invention concerne un nouveau verre de prescription (58), courbe, conçu notamment pour des applications ophtalmiques et pour être fabriqué sous forme d'une feuille plate mince et être courbé, après ou pendant la fabrication, afin de prendre la forme arquée requise et préalablement définie. Il n'existe pratiquement aucun rapport entre, d'une part, l'épaisseur du verre et sa forme arquée macroscopique et, d'autre part, ses caractéristiques optiques. Le concepteur du verre détermine les surfaces macroscopiques du verre arqué (59, 60), comme il le souhaite. Le processus de conception implique que les emplacements de l'objet (50), du verre (51) et de l'image requise (53) sont connus. En utilisant la technique du lancé de rayons, on calcule les droites microscopiques perpendiculaires au verre qui vont former l'image requise. La forme arquée est alors transformée en une forme plate. A partir des droites perpendiculaires microscopiques transformées, on calcule la surface microscopique à l'aide d'un processus d'addition continu des pentes présentant un modèle géométrique. La surface finale n'est pas lisse mais contient beaucoup de formes microscopiques denses du type en dents de scie. Cette surface rugueuse permet au verre d'avoir n'importe quelle forme et épaisseur voulue. Ce verre peut constituer une variante aux verres de prescription classiques. Il peut être fixé ou attaché à des verres de lunettes courbes, non prescrits, afin de les transformer en verres de prescription. Ce verre peut être suffisamment fin et souple pour permettre aux personnes de couper et mettre en forme leurs verres, comme ils le souhaitent, à l'aide de simples accessoires de coupe comme des ciseaux. Le verre peut être d'un poids très léger, être élastique, produit en masse à bon marché, être très grand, comporter de très fortes ou de très faibles aberrations, être revêtu, teinté, ou présenter une combinaison de ces caractéristiques, et il peut être également stratifié. L'invention concerne en outre des miroirs arqués à un seul ou à plusieurs foyers, pouvant être souples.
