Title: Data conversion mechanism for computer system
Inventor: JONES GARY WAYNE
IPC: G06F9/44
Filed: 1997-04-10
Abstract: A computer system comprises first and second software components, such as for example TUXEDO software and a Visual Basic application.  A first data structure definition file (e.g. a C header file) represents a data structure from the point of view of the first software component.  A software tool processes the first data structure to generate a second structure definition file (e.g. Visual Basic Types) representing the data structure from the point of view of the second software component, and at the same time to generate a compact coded representation of the data structure.  A conversion function is provided, for converting an instance of the data structure represented by the first structure definition file into an instance of the data structure represented by the second structure definition file, and vice versa, using the compact coded representation to control the conversion.

Title: Methods and devices for immunizing a host to tumor-associated antigens through administration of naked polynucleotides which encode tumor-associated antigenic peptides
Inventor: RAZ EYAL
IPC: A61P37/04
Filed: 1995-11-01
Abstract: The invention is directed to methods for introducing biologically active peptides into a host administration of polynucleotides which operatively encode for the peptide of interest. In a preferred embodiment of the invention, a host who has been identified as having a tumor bearing at least one tumor-associated antigen is the recipient of a polynucleotide which operatively encodes for a foreign mimic of the tumor-associated antigen or a mutation of the self-antigen. The antigen-encoding polynucleotides are administered to host tissues which have a high concentration of antigen presenting cells in them relative to other host tissues. The method is particularly useful in treating cancer through induction of antigen-specific cytotoxic T lymphocytes in the host for lysis of tumor cells bearing the antigen. Devices and compositions for use in the methods of the invention are also described.

Title: Improved rinse water additive dispenser
Inventor: MCKIBBEN GARY EUGENE
IPC: D06F39/02
Filed: 1998-03-24
Abstract: An improved rinse water additive dispenser for an automatic washer has a substantially rigid body having a resilient portion and an internal volume. The dispenser further includes an opening therein and a valve for sealing the opening closed so that the rinse water additive is maintained within the dispenser until the valve is acted upon by centrifugal force applied to the dispenser during a spin cycle of the automatic washer to unseat the valve. The resilient portion provides for volumetric expansion and contraction of the dispenser when the dispenser is placed in variable temperature water. The volumetric expansion and contraction substantially relieves an air pressure differential between ambient and the internal volume so that the centrifugal force unseats the valve without interference from the pressure differential. The opening may be in the resilient portion or in the substantially rigid body.

Filed: 1998-06-26
Abstract: A system and method is described for importing data from a source computer system, manipulating and transforming of that data, and exporting the data to a target computer system under control of a script processor using stored metadata definitions. Metadata is used to describe the properties of the data being manipulated.      The system includes a means for manipulating the metadata definitions. The metadata definitions are created to import data into the system, export data from the system, create views of the external data, store generic format data within the system, manipulate generic format data within the system and to control data flow through the system. Data is imported into the system using an import data definition to map the external data into an import data bag. Data imported into an import data bag becomes independent of the original data source. Data is manipulated within the system using script control commands and data is transformed within the system using rule sets that act upon data bags. Data is exported from the system using an export data definition to map the import data bag into the required export data bag format and then to write data in the export data bag to the external data target.
