Title: Non-Unique Seismic Lithologic Inversion for Subterranean Modeling
Inventor: NEFF DENNIS B
IPC: G01V1/28
Filed: 1996-05-30
Abstract: A method of modeling subsurface reservoir conditions deals with non-uniqueness of seismic reflection signals with respect to reservoir conditions by proposing and then comparing both seismic and lithologic data for forward model sites to select the most likely model for each site. Forward modeling techniques are used to build a synthetic seismic trace catalog, which includes a range of corresponding pseudo-logs for reservoir characteristics that could reasonably exist within a defined region. Then each synthetic seismic trace in the catalog is compared against every real seismic trace, and a number (e.g., 10 to 50) of synthetic traces is selected for association with each real trace that best match the real trace. Finally, the pseudo-logs corresponding to the number of selected synthetic seismic traces for each forward model site are compared to the pseudo-logs selected for adjacent sites to select the most lithologically coherent pseudo-log at each site for use in generating a model display of reservoir characteristics.

Patent CA-2179552-A1 (CA)
Inventor: RAZAVI BEHZAD
IPC: H03D7/00
Filed: 1996-06-20
Abstract: A low noise amplifier (LNA)/mixer/frequency synthesizer circuit for the front end of a RF system. The LNA/mixer/frequency synthesizer circuit is fabricated as an integrated circuit utilizing 0.6 µM CMOS technologies. The LNA within the circuit is provided a bias current from a power supply. Due to the CMOS construction of the LNA, a significant amount of unused power is available within the LNA. The frequency synthesizer requires the same bias current as does the LNA. The frequency synthesizer is directly coupled to the LNA, wherein the unused bias current of the LNA is used to supply the required bias current to the oscillators within the frequency synthesizer. Since the bias current used by the frequency synthesizer is drawn from the surplus of the LNA, a RF system front end is provided that has greatly reduced power requirements. The LNA is coupled to the frequency synthesizer, via an inductor. The inductor provides resonance to a node between the LNA and the frequency synthesizer that joins to the mixer. The inductor suppresses band harmonics while preserving the unused bias current.

Abstract: An attachment for mounting a backhoe type bucket on a front-end loader having lifting arms for tiltably holding a wide bucket and hydraulic tilting cylinders for tilting the wide bucket, and which allows the front-end loader to be used as a backhoe. The attachment comprises a frame suitable for attachment to the front-end loader mechanism in the absence of the wide bucket, the frame having end connector parts with a lower pair of pivots attachable to the lifting arms and with an upper pair of pivots attachable to the hydraulic tilting cylinders. The lower and upper pairs of pivots lie in a common plane, and a bucket arm carrying a backhoe bucket is connected to the frame by pivot means allowing movement of the bucket arm relative to the frame about a pivot axis which is so related to the common plane of the frame pivots that when the common plane is vertical this pivot axis extends fore-and-aft of the front-end loader and the backhoe bucket is close to its lowest position. A hydraulic cylinder directly connects the bucket arm to the frame for swinging the bucket arm sideways relative to the front-end loader about the pivot axis to allow material to be dumped from the backhoe bucket beside a trench or hole being dug without movement of the front-end loader.

Title: Modified cells and methods for inhibiting hyperacute rejection of xenogeneic transplants
Inventor: EDGE ALBERT
IPC: A61K38/00
Filed: 1995-05-17
Abstract: Modified cells for transplantation having reduced capacity to stimulate natural antibody-mediated hyperacute rejection of the cell in a transplant recipient are disclosed. In unmodified form, cells for use in xenogeneic transplantation express at least one epitope on a cell surface antigen which is bound by natural antibodies in a recipient. Prior to transplantation, the cells are modified to alter, reduce or substantially eliminate expression of the epitope on the cell surface. Preferably, the cell is a porcine cell and the epitope is a galactosyl (.alpha.1,3) galactose epitope. Methods for reducing the immunogenicity of a cell for transplantation into a recipient are also disclosed. Modified cells of the invention can additionally be treated to alter, reduce or substantially eliminate another surface antigen (e.g., an MHC class I antigen) which stimulates a cellular immune response against the cell in a recipient. Additionally, a recipient can be treated with an agent which inhibits T cell activity, such as an immunosuppressive drug or an anti-T cell antibody.

Abstract: A gas phase process for the production of titanium dioxide powders having well-controlled crystalline and surface area characteristics is disclosed. In this process, which is preferably carried out in a laminar diffusion flame reactor, vapor phase TiCl4 and oxygen are mixed in a reaction area which is heated externally. The titanium dioxide powder formed is then collected. It is preferred that the heat source used be a hydrocarbon fueled (e.g., methane) flame. Optionally, a vapor phase dopant (such as SiCl4) may be added to the reaction mixture to desirably affect the physical properties of the titanium dioxide produced. In a particularly preferred embodiment, a corona electric field is positioned across the area where the combustion reaction takes place (i.e., the reaction area). High anatase, high surface area titanium dioxide powders made by this process are excellent photocatalysts. The products of this process and the use of those products as photocatalysts are also disclosed. This process is also useful for producing other ceramic powders (such as silicon dioxide and tin oxide), as well as pure metallic or alloy powders.
