Title: Methods and compositions for enhancing immune response and for the production of in vitro mabs
Inventor: TAMARKIN LAWRENCE
IPC: A61K39/00
Filed: 1998-11-10
Granted: 2011-04-26
Abstract: The methods and compositions of the present invention are directed to enhancing an immune response and increasing vaccine efficacy through the simultaneous or sequential targeting of specific immune system components.  More particularly, specific immune components, such as macrophages, dentritic cells, B cells and T cells, are individually activated by component-specific immunostimulating agents. One such component-specific immunostimulating agent is an antigen-specific, species-specific monoclonal antibody. The invention is also directed to a method for the in vitro production of the antigen-specific, species-specific monoclonal antibodies which relies upon the in vitro conversion of blood-borne immune cells, such as macrophages and lymphocytes.  Vaccine efficacy is enhanced by the administration of compositions containing component-specific immunostimulating agents and other elements, such as antigens or carrier particles, such as colloidal methods, such as gold.

Title: Morphing image processing system using polygon reduction processing
Inventor: ARAI MASATOSHI
IPC: G06T13/20
Filed: 2000-07-28
Granted: 2006-03-28
Abstract: A first image before deformation and a second image after deformation are input and formed into polygon models represented with a polygon mesh by a polygon model generation. processing part. Polygon reduction processing is performed by a low progression level polygon model generation processing part to generate low progression level polygon models having a reduced number of polygons and metadata containing the reduction process of the number of polygons. A low progression level polygon model morphing processing part specifies corresponding vertices between the low progression level polygon models, and then they are formed into intermediate low progression level polygon models by interpolation. Intermediate images are generated by reproducing processing to the polygon model using the metadata by an intermediate image generation processing part and texture mapping.

Title: Method for producing long-chain polyetherpolyols without reprocessing
Inventor: GUPTA PRAMOD
IPC: C08G65/26
Filed: 1999-04-08
Granted: 2008-07-15
Abstract: The invention relates to a method for producing long-chain polyetherpolyols without reprocessing. Oligomeric alkoxylated initiation compounds with molecular weights of between 200 and 1000 are obtained first from low- molecular initiators by catalysis with perfluoroalkyl sulfonates of metals of Group III A of the periodic table (in accordance with the IUPAC Convention of 1970), through reaction with alkylene oxides at reaction temperatures of 80 to 200oC and with concentrations of the catalyst of 5 to 200 ppm. Said initiation compounds are then reacted with alkylene oxides to produce higher-molecular long-chain polyether polyols without being reprocessed and without the catalyst being separated, using highly active DMC catalysts, the concentration of catalysts being 30 ppm or less in relation to the quantity of polyether polyol to be produced.

Granted: 2006-06-13
Abstract: A system is disclosed for providing direct automated access to an online information services provider through an address embedded in a video or audio program, commercial message, or news story. The system operates with video or audio programs which are received through broadcast, cable or pre-recorded media, and which are encoded in either analog or digital formats.      The address of an online information provider is encoded in a vertical blanking interval or other non-displayed portion, of an electronic signal which represents the video or audio program so as not to interfere with the program as displayed or transduced on a television or audio sound system. The online information provider address is detected and decoded from the electronic signal and used in establishing a direct digital communication link to the online information provider.      Upon detecting an online provider address, the system indicates to the user that more information is available. The user may then elect to establish a connection with the online information provider by giving a simple command, e.g.. pushing a special button on a remote control. The system then automatically establishes a direct digital communication link to the online information provider through the address and provides for interactive information exchange and processing to permit signals received from the online information provider to be displayed on a conventional television, transduced on a sound system, or also on a high resolution reproducing system such as a computer monitor, or other reproduction device.

Abstract: A submersible centrifugal pump for downhole pumping of methane-saturated water from wells drilled in coal formations, has an electric motor-driven vertical shaft having centrifugal impellers distributed therealong, each impeller being located in a stationary diffuser within the pump wall to form a multi-stage pump. A concentric shroud is located at the lower portion of the pump wall. It is sealed with the pump wall such that all fluid to be pumped must enter holes near the top of the shroud and travel downward through an annulus to the pump inlet. A charge impeller and a solids grinder are located at the lower end of the pump central shaft. The multi-stage centrifugal pump is located above the solids grinder and includes multiple compression stages of diminishing volume as the methane and fluid mixture travels upward through the pump. Another charge impeller may be located at the upper end of the shaft at the outlet pipe. Pressure equalization vents allow fluid flow from the fourth centrifugal stage to the pump-shroud annulus to maintain pump prime. Centrifugal impellers, each having a hub extending upward and downward along the length of the driving shaft such as to rest upon each other in turn, while avoiding contact with the stationary diffusers.
