Patent CA-2391759-A1 (CA)
Inventor: RAJANIEMI JAAKKO
IPC: H04W36/12
Filed: 2000-04-26
Abstract: A method for indicating a mobile station's (MS) location. A first radio network controller, RNC, acts as the mobile station's serving RNC (SRNC), for reporting the mobile station's location to the core network (CN). A second RNC acts as the mobile station's drift RNC (DRNC), for maintaining a radio connection with the mobile station. In response to fulfilment of at least one criterion in a first set of criteria, the mobile station (MS) sends location information about its location to the second RNC (DRNC) which forwards the location information to the first RNC (SRNC) for reporting to the core network (CN). There is also a second set of criteria for transforming the location information. In response to fulfilment of at least one criterion in the second set, the first RNC (SRNC) sends falsified information about the mobile station's location to the core network (CN).

Abstract: L'invention concerne un système de télémesure par câble et procédé permettant de transmettre des données sur des fréquences porteuses multiples. Ce système et ce procédé permettent un réglage du niveau de puissance ainsi que du nombre de bits par porteuse pour l'utilisation optimale ou presque optimale de la capacité du câble. En raison de la nature de la télémesure par câble, le niveau de puissance total est limité seulement par les capacités d'entrée de la cartouche de télémesure de fond et par les restrictions de puissance d'entrée du récepteur de l'unité de télémesure du haut du trou. Le niveau de puissance optimal est déterminé pendant une séquence d'exercice et est fonction de facteurs tels que la longueur, le matériau, la température et la géométrie du câble. Les transmissions montantes et descendantes sont exécutées au moyen de différentes techniques de modulation.
Patent CA-2398475-A1 (CA)
Inventor: ZIKELI STEFAN
IPC: B29C48/475
Filed: 2000-11-20
Abstract: The present invention relates to a buffer tank as is substantially used for ensuring a constant supply of the spinning machine with a polymer melt in spinning machines. To this end the buffer tank is provided with a compensation chamber whose volume is variable in response to a pressure prevailing in the polymer melt and to a volume flow variation. The polymer melt flows from a polymer melt entry opening to a polymer melt exit opening through the compensation chamber. It is the object of the present invention to make the flow through the compensation chamber uniform. The residence time of the polymer melt in the compensation chamber shall thereby be prevented from having a wide range, the latter resulting in an irregular quality of the yarns produced by the spinning machine because of the time-dependent, mechanical and chemical properties of the polymer melt. To achieve said object, the compensation chamber is provided for flow optimization with at least one flow guiding element projecting into the flow of the polymer melt, which is smaller than the flow cross-section of the compensation chamber and by which the velocity profile in the direction of flow through the compensation chamber is made uniform at least in sections.

Abstract: Systems, apparatuses and methods for cell isolation and analysis. Cells are introduced into a dielectrophoretic prefilter including one or more trapping  electrodes configured to trap at least a portion of the cells with a dielectrophoretic force. The cells trapped from the prefilter are directed into a dielectrophoretic field-flow fractionation separator coupled to the prefilter. The cells are discriminated by balancing a dielectrophoretic forc e ( and optionally a magnetophoretic force) with a gravitational force to displace the cells to positions within a velocity profile in the separator. At least a portion of the cells are trapped as a function of the cells' time of  emergence from the separator with two or more spiral electrode segments coupled to the separator.

IPC: A01G23/14
Filed: 2003-01-15
Abstract: Le système de collecte de la sève au moyen de tubulures est un système fermé qui opère généralement par succion à une pression inférieure à la pression atmosphérique. Avant l'entaille, il est possible pour le producteur de laver le système de tubulures fines étant donné qu'il n'est pas branché sur les chalumeaux. Par la suite, au cours de la saison , étant donné son étanchéité, la configuration du système ne permet pas un lavage à contre courant (back-flush). Un tel lavage permettrait d'éliminer les bactéries champignons et moisissures qui s'accumulent dans la fine tubulure en raison de la présence de sucres et de la chaleur Pour corriger cette situation et permettre un lavage du systèm e à n'importe lequel moment de la récolte, nous proposons l'introduction d'une soupape au niveau du chalumeau qui permettrait une relâche de la solution à l'extrémité du réseau de tubulures lors d'un lavage à contre-sens

IPC: C08J7/043
Filed: 2003-02-17
Abstract: A composite article includes an acrylic layer, a UV-cured layer formed from a UV-curable composition, and a polyurethane backing layer. A method of forming the composite article includes applying the UV-curable composition to the acrylic layer such that the composition is between the acrylic layer and the polyurethane backing layer to enhance bonding between these layers. The UV-curable composition includes at least one monomer which is an ethylenically unsaturated methacrylate monomer, an ethylenically unsaturated acrylate monomer, or both. The at least one monomer has a hydroxy functional group. The monomer is compatible with the acrylic layer and the hydroxy functional group of the monomer is reactive with a polyisocyanate from the polyurethane backing layer. The UV-curable composition also includes a curing initiator that is reactive with the monomer. Upon exposure of the UV-curable composition to UV electromagnetic radiation, the curing initiator enables the composition to cure to the acrylic layer.

Abstract: A method of determining the distribution of shales, sands and water in a reservoir including laminated shaly sands using vertical and horizontal conductivities derived from nuclear, NMR, and multi-component induction data such as from a Transverse Induction Logging Tool (TILT). From the resistivities of the sand laminate, empirical realtions are used to predict anisotropic reservoir properties of the reservoir. The TILT data are inverted based on anisotropic assumptions about laminated shale, with bulk permeability as a measurement (103) constraint; and an assumption that sand comprises a number of intrinsically isotropic layers which gives a model such as a Thomas-Stieber and Waxman-Smits model, that comrises laminated sands including water and dispersed clay, laminated shales and clay-bound water is isotropic.  Estimates of inverted shale volume are compared to the estimate from nuclear logs. A difference between the two estimates is an indication that the sands may be anisotropic. A check is made to see if a bulk water volume determined from the inversion is greater than a bulk irreducible water volume from NMR  measurements. NMR data are then used ot obtain sand distribution in the reservoir.

Abstract: A pipefitter's protractor is used to measure the angle between two separate pipes having an intersecting point. The protractor assembly includes a pipe attachment bar secured to the squared end of one pipe, with a protractor arm extending from the center of the pipe attachment bar and concentric with the centerline of the pipe. The protractor extends from the arm, with the arm and protractor rotating about the pipe attachment bar fitting to align the protractor plate coplanar with the plane defined by the pipes. The protractor is adjusted along the protractor arm to position the protractor origin at the intersection of the pipe centerlines, and a line is run from the origin to the center of the second pipe. The angle between the pipes and the distances from the protractor origin to the ends of each pipe are then used for fabricating an elbow to join the pipes.

Abstract: Existing electronic hair removal machines have a built-in tester that allows one to easily test the continuity of the central wire of the needle holder cable. However, existing testers on these machines cannot test the continuity of the shielding of the needle holder cable. When the shielding in these cables has a break in continuity, the esthetician using the machine might mistakenly judge that the entire machine is defective rather than just the cable.   The invented tester allows one to quickly test the continuity of the cable's central wire and the shielding simultaneously, to show that only the needle holder cable is defective and not the entire machine. The esthetician can then confidently replace only the cable, rather than sending the entire machine for costly repairs.
