Patent CA-2286912-A1 (CA)
Inventor: BRODY GEORGE
IPC: H04M3/58
Filed: 1998-02-11
Abstract: L'invention porte sur un procédé de prise d'appel par un second dispositif de communication après mise en garde de l'appel par un premier dispositif de communication sans tenir compte du type du dispositif de communication ou si celui-ci se trouve dans un réseau fermé. Ce procédé consiste à détecter, par un serveur associé au premier dispositif de communication, la mise en garde d'un appel effectuée par le premier dispositif de communication et à suspendre ensuite l'appel. Puis, le serveur associé au premier dispositif de communication attend un message de prise d'appel directif qui peut être envoyé par le premier dispositif de communication ou provenir directement d'un second dispositif de communication ou être envoyé par l'intermédiaire d'un serveur associé au second dispositif de communication. Lorsque le serveur associé au premier dispositif de communication reçoit le message de prise d'appel directif, il le communique au serveur associé au second dispositif de communication. Cette communication établit une liaison entre les serveurs de sorte que l'appel puisse être pris par le second dispositif de communication.

Title: Method for purifying fsh
Inventor: VAN HORN ERIK
IPC: C07K14/59
Filed: 1999-11-22
Abstract: The present invention provides a method for purifying follicle stimulating hormone (FSH) from biological samples, for example, from human pituitary glands or human postmenopausal urine, wherein the FSH is contaminated with other proteins, by use of dye-ligand affinity chromatography (DAC). Depending on the starting material used and the initial purity of FSH in the starting material, additional purification steps may be employed. These steps preferably involve the use of hydrophobic interaction chromatography. This process may be used to generate affinity pure FSH suitable for therapeutic applications. The methods of the invention provide high purity FSH with high overall yield. A further advantage is the ability to easily regenerate the chromatography media for re-use, thus providing added economy to the purification process.

The arrangement of the coils (32, 36) and the core assemblies (30, 34) is such that substantially all of the magnetic flux generated when the apparatus is seated on the pipe (28) and the coil is energised is contained within the core assembly and within the wall of the pipe (28). Advantageously, the core assemblies (30, 34) have E-sections profiles, the ends of the limbs of the E-sections comprising the lowermost surfaces of the core assemblies and the coils being wound about the central limbs of the E-sections. The core assembly is formed from a plurality of part-annular segments, each segment having an individual induction coil associated therewith. The apparatus may comprise first and second heating assemblies, the first extending around the outer periphery of a circular weld zone defined on the exterior surface of said second length of pipe and the second extending around the inner periphery of the weld zone.

Title: Process and apparatus for production of bi-213 cations
Inventor: CHIARIZIA RENATO
IPC: G21F9/00
Filed: 1998-06-03
Abstract: A process for producing substantially impurity-free Bi-213 cations is disclosed. An aqueous acid feed solution containing Ac-225 cations is contacted with an ion exchange medium to bind the Ac-225 cations and form an Ac-225-laden ion exchange medium. The bound Ac-225 incubates on the ion exchange medium to form Bi-213 cations by radioactive decay. The Bi-213 cations are then recovered from the Ac-225-laden ion exchange medium to form a substantially impurity-free aqueous Bi-213 cation acid solution. An apparatus for carrying out this process is also disclosed.

Title: Method for increasing the efficiency of recombinant aav production
Inventor: SNYDER RICHARD
IPC: C12N5/10
Filed: 1998-08-07
Abstract: The present invention relates to methods and compositions for increasing the production of high titer stocks or recombinant AAV (rAAV) through regulation of expression of the AAV REP and CAP proteins. The methods and compositions of the invention are based on the observation that the low level expression of the AAV REP 78/68 protein increases the production of AAV viral capsid protein and efficiency of packaging resulting in production of higher titer recombinant viral stocks. The invention encompasses recombinant AAV vectors that direct the expression of AAV REP and CAP proteins and the use of such vectors for the production of novel stable cell lines capable of generating high titer rAAV vectors. The invention provides methods for regulating the expression of the AAV REP 78/68, REP 40/52 and CAP gene at the transcriptional and post-transcriptional level.

Patent CA-2305185-A1 (CA)
Inventor: MOON BILLY GAYLE
IPC: G06F9/44
Filed: 1998-10-02
Abstract: A method for processing information using a personal digital assistant utilizes a standardized status bar manager ("SBM") and status bar interfaces.  All applications and the operating system's launch pad support the status bar which can be uniformly used to both show and interact with status bar messages. The SBM links together all of the status bar areas of all applications (and the operating system launch pad as well) whenever necessary.  The present invention routes global status messages corresponding to incoming events to each status bar of every active application. The SBM also routes all messages to the status bar, regardless whether the message requires an action by the user or is for information only. Minimized applications are displayed on and launched from a status bar of an active application without having to first access the operating system launch pad. Finally, the SBM creates an unanswered telephone call list that includes a reason code explaining why the call went unanswered.

IPC: G01N1/00
Filed: 2000-04-17
Abstract: A fixed volume liquid transfer device defined by a small bore tube having an open end for collection of liquids and a plunger in the tube is disclosed. A piston is mounted around the open end and an air plug is mounted in the piston adjacent the open end. Liquid in a test tube is transferred to a testing site by inserting the transfer device into the test tube.      As the piston contacts the liquid, the liquid is pumped into the tube. As the transfer device is inserted further, the air plug is actuated to balance air pressure across the piston.      The device may then be withdrawn from the test tube and transported to a test site. At the test site, the plunger is depressed to expel the liquid into a testing device.

Filed: 1999-09-23
Abstract: The present invention relates to a transformer having a conductive element spiraling along the length of an insulated wire of the coil. When formed into plurality of adjacent turns, the conductive element couples one of the plurality of turns with another of the plurality of turns. The conductive element increases the series capacitance of the transformer circuit. A resistive element may also spiral along the length of the insulated wire to couple one of the plurality of turns with another of the plurality of turns. The resistive element not only increases the series capacitance of the transformer, but also increases the series conductance of the transformer circuit. The increase in the series resistance increases the dampening of the switching resonance.
