Patent CA-2270252-A1 (CA)
Title: Seabed sonar matrix system
Inventor: GUIGNE JACQUES YVES
IPC: G01S15/10
Filed: 1999-04-27
Abstract: A system for sonically probing a seabed comprises at least one row (14, 100) of transducers (22, T1, T2, TZ) that each can produce a sonic beam, and a corresponding row of sonic detectors (24, D1, D2). Each transducer is independently energized to produce a narrow sonic beam (40), with resulting seabed or subsea echoes being detected to produce one pixel of a display (60, 80, 90, 150) formed by an X-Y array of pixels, before a next transducer is energized and its echoes are detected to produce another pixel of the display.    When the system detects a large change in echo amplitude at adjacent seabed locations, then scanning at those locations is accentuated by analysis and by additional sonification at different frequencies. The transducers are closely spaced, at a center-to-center distance (G) of typically about 3.5 cm, to provide good horizontal resolution. Each transducer is energized to produce a sonic pulse which, dependent on the application, has a carrier frequency (32) such as 2mHz, 1 mHz, 500kHz or 100kHz. This results in an optimized narrow sonic beam, with each pulse having a duration (A) on the order of 10 to 100 microseconds to produce a modulation frequency on the order of 200kHz to 5Khz, and with each pulse having a high maximum energy to create a wide frequency bandwidth in the seabed.

Abstract: Provided are novel DT- and ETA-based immunotoxins and a method of treating an immune system disorder not involving T cell proliferation, comprising administering to the animal an immunotoxin comprising a mutant diphtheria toxin moiety linked to an antibody moiety which routes by the anti-CD3 pathway, or derivatives thereof under conditions such that the disorder is treated. Thus, the present method can treat graft-versus-host disease. Also provided is a method of inhibiting a rejection response by inducing immune tolerance in a recipient to a foreign mammalian donor tissue or cells, comprising the steps of: a) exposing the recipient to an immunotoxin so as to reduce the recipients' peripheral blood T-cell lymphocyte population by at least 80%, wherein the immunotoxin is anti-CD3 antibody linked to a diphtheria protein toxin, wherein the protein has a binding site mutation; and b) transplanting the donor cells into the recipient, whereby a rejection response by the recipient to the donor organ cell is inhibited, and the host is tolerized to the donor cell.
Patent CA-2287308-A1 (CA)
Title: Method and apparatus for enhancing gas turbo machinery flow
Inventor: NORRIS THOMAS R
IPC: F01D25/30
Filed: 1998-03-17
Abstract: In a conduit (D) constituting the outlet from turbo machinery such as a turbine or compressor, stall gas (G0, G7) high static pressure and low velocity is collected. This stall gas is then routed through struts (S) - preferably teardrop shaped - to more central low static pressure and high velocity gas flow areas. At these areas, the gas is discharged, preferably through multiple manifold openings (24). Mixing of the collected high static pressure, low velocity stall gas with the low static pressure, high velocity main stream gas occurs. Turbine noise, vibration, and back pressure are decreased with resulting improvements of efficiency. Variations are illustrated including adaptation of gas flow transfer utilizing turning vanes (72), fairings, rectangular duct turns (fig. 5a, b), and struts (fig. 6c) for placement in turbine turbo machine outlets having high turbulence or variable swirl.

Title: Monitoring of downhole parameters and tools utilizing fiber optics
Inventor: WILLIAMS GLYNN
IPC: E21B47/10
Filed: 1998-05-01
Abstract: The present invention provides systems utilizing fiber optics for monitoring downhole parameters and the operation and conditions of downhole tools. In one system fiber optics sensors are placed in the wellbore to make distributed measurements for determining the fluid parameters including temperature, pressure, fluid flow, fluid constituents and chemical properties. Optical spectrometric sensors are employed for monitoring chemical properties in the wellbore and at the surface for chemical injection systems. Fiber optic sensors are utilized to determine formation properties including resistivity and acoustic properties compensated for temperature effects. Fiber optic sensors are used to monitor the operation and condition of downhole devices including electrical submersible pumps and flow control devices. In one embodiment, a common fluid line is used to monitor downhole parameters and to operate hydraulically-operated devices. Fiber optic sensors are also deployed to monitor the physical condition of power lines supplying high electric power to downhole equipment. A light cell disposed downhole is used to generate electric power in the wellbore, which is used to charge batteries.

Patent CA-2292844-A1 (CA)
Title: D-amino acid oxidase promoter from t. variabilis
Inventor: LIU SUO W
IPC: C12N9/16
Filed: 1998-06-08
Abstract: A D-amino acid oxidases promoter isolated from T. variabilis has been incorporated into S. cerevisiae expression vectors to increase the expression of heterologous genes. The heterologous promoter has been placed upstream of selective markers, auxotrophic nutritional and/or dominant selectable markers. Because the promoter is from another yeast specie, it is weakly recognized by S. cerevisiae. To compensate for the weak transcripts of selectable marker genes transcribed from the weak heterologous promoter, the plasmid containing the gene of the interest is amplified leading to a higher expression of protein of interest.

Title: Casing annulus remediation system
Inventor: ROPP R LEWIS
IPC: E21B34/02
Filed: 1998-06-09
Abstract: A casing annulus remediation system for overcoming problems associated with lowering a flexible hose (51) into an annulus (21) between strings (13, 15, 17, 19) of casing in a petroleum well by pressurizing the hose (51) so that the hose is rigid and may be forced down the annulus. A nozzle (65) is affixed to the lower end of the hose. The hose may be inserted several hundred feet into the well. Therefore, the hose (51) is pressurized to maintain rigidity to keep the hose from winding about the well during deployment. To keep the hose rigid internal pressure is maintained in the hose (51). The nozzle (65) is provided with a burst disk (69) that holds the pressure. Once the hose is lowered to a desired depth, an operator may increase the pressure sufficiently in the hose to break the disk (69), thereby allowing heavy liquid to flow out.

Patent CA-2302403-A1 (CA)
Inventor: KRIEGER MONTY
IPC: C07K14/705
Filed: 1998-09-04
Abstract: L'invention concerne le SR-BI qui est présent dans les membranes d'hépatocytes et de tissus stéroïdogènes, y compris dans la glande surrénale, les testicules et les ovaires, où il régule le prélèvement et le transport d'ester de cholestéryle à partir de lipoprotéines de haute densité. Il a été démontré que des animaux transgéniques ne produisant pas de SR-BI sont en parfaite santé, à l'exception de l'infertilité des femelles. Cela prouve qu'une inhibition du prélèvement, de la liaison ou du transport de l'ester de cholestéryle à SR-BI peut s'utiliser pour inhiber la grossesse. On peut également utiliser la même voie pour réduire la production de stéroïdes, et donc l'utiliser comme thérapie de troubles induisant une surproduction de stéroïdes.

Title: Method and apparatus for surveillance in communications networks
Inventor: SPARGO GLENN
IPC: H04L12/26
Filed: 1998-11-13
Abstract: Control of network surveillance in communications networks is accomplished by dividing the surveillance task into two sub-tasks. The first sub-task automatically identifies communications within the network which are to be monitored. Such identification is accomplished by the application of a reasoning system to data received from the network. The identification of the data to be monitored is received by the second sub-task along with network topology information. The second sub-task also applies a reasoning system to this data in order to configure probes and switches within the network so that the identified data can be captured.
