Patent CA-2215540-A1 (CA)
Inventor: SAKAKIBARA TOSHIKAZU
IPC: G06F17/30
Filed: 1997-09-15
Abstract: A method of using a DOS file system to access a file in a database is provided. In one embodiment implemented in an on-board vehicle navigation system, the file includes map data for a given geographic area. A file access table (FAT) is associated with the file system and references the file. The FAT has a plurality of locations, each location including a reference to one of the data clusters of the file and to another location in the FAT, forminga linked list of the references. The logical order in which the data clusters occur within the file is determined by following the linked list in the FAT for that file. A cluster table is then constructed for the file. The references to the data clusters are stored in consecutive locations of the cluster table accordingto the logical order of the data clusters within the file. The file is then accessed by sequentially accessing the consecutive locations in the cluster table to retrieve the data clusters.

Title: Method for treatment of cancer and infectious diseases and compositions useful in same
Inventor: MAYHEW MARK
IPC: A61K38/00
Filed: 1996-08-16
Abstract: Administration of expressible polynucleotides encoding eukaryotic heat shock proteins to mammalian cells leads to the stimulation of an immune response to antigens present in those cells. This makes it possible to stimulate an immune response to target antigens, including target tumor antigens or antigens associated with an infectious disease, without having to isolate a unique antigen or antigen-associated heat shock protein for each target antigen by administering to a mammalian subject or to a group of mammalian cells containing the antigen, an expressible polynucleotide encoding a heat shock protein. The expressed heat shock protein may have the same structure as native heat shock proteins, or may be a modified form adapted to control the trafficking of the expressed heat shock protein within the cells.

Title: Receptor specific chimeric viral surface polypeptides for viral and particle incorporation and internalization in target cells
Inventor: ROSENBERG STEVEN
IPC: C12N15/86
Filed: 1996-12-02
Abstract: Viral and non-viral particles can be incorporated by chimeric viral surface polypeptides that are constructed to include a portion of a viral surface polypeptide and a portion of a ligand specific for a receptor of the LDLreceptor family. Particles incorporated by the chimeras can target cells specific for the receptor type for which the chimera is designed, and can be internalized in these cells. Exemplary models of the invention include chimeras constructed with a ligand portion of a SERPIN, for example PAI-1, for targeting cells expressing uPAR bound uPA, and for forming an internalizable complex upon contact with LRP cell surface receptor. Accordingly, when the particle is internalized in the target cell, so is any genome or polynucleotide encoding a polypeptide for expression that is contained in the viral or non-viral particle. Cell specific gene therapy protocols are thereby accomplished by the invention.

Title: Liquid dispensing apparatus and method
Inventor: ROBERTS BENJAMIN R
IPC: B24B37/04
Filed: 1998-09-25
Abstract: A liquid dispensing method and apparatus in which liquid is dispensed from chambers, that can be pressure vessels, to a flow circuit. A valve network is designed such that when one chamber functions in a dispense mode of operation another chamber functions in a return mode of operation in which unused liquid is sent back to such chamber so that liquid is continually circulated. The chamber or vessel undergoing the return mode of operation is vented through a valve that is either a pressure regulation valve having a set point of pressure or a remotely activated control valve response to liquid pressure at the point of use. In such manner internal pressure within the chamber or pressure vessel undergoing the return mode of operation is regulated to in turn regulate liquid pressure at the point of use. In case of pressure vessel operation, gas pressure within each pressure vessel can also be regulated in conjunction with internal pressure during the return mode to in turn regulate liquid pressure at the point of use. As a result of such pressure regulation, constant flow rate of liquid through the flow circuit and at the point or points of use can be assured.
