Title: Detection of alterations in a gene by long range pcr using human mobile elements
Inventor: BLONDAL THORARINN
IPC: C12Q1/68
Filed: 2000-09-06
Abstract: Methods are described for detecting an alteration in a gene of interest, suc h as a deletion in the C4A gene (e.g., for detecting C4AQ0), by performing lon g range polymerase chain reaction amplification on a test sample comprising genomic DNA. The methods amplify target DNA comprising all or a portion of a  human mobile element (e.g., a retroviral insert in intron 9 of the C4A gene) , using primers designed such that PCR products are formed only if the test sample comprises genomic DNA comprising the alteration in the gene of interest; alternatively, the methods amplify target DNA using primers design ed such that PCR products are formed only if the test sample comprises genomic DNA that does not comprise the alteration in the gene of interest. Alternatively, primers are designed such that PCR products have detectably different sizes, depending on whether or the test sample comprises genomic D NA that comprises the alteration in the gene of interest. The methods can be us ed to identify whether an individual is at risk for a disease or condition associated with the alteration in the gene of interest, as the presence of t he alteration correlates with risk for the disease.

Title: 2-azapurine compounds and their use
Inventor: BERGMANN FRANK
IPC: C12Q1/6813
Filed: 2000-08-28
Abstract: Within oligonucleotides 2-azapurine and especially 2-azaadenine bases form specifically base pairs with guanine.  This base pair is of analogous stability as an adenine-thymine but less stable than a guanine-cytosine base pair. Therefore, the incorporation of 2-azaadenine residues into oligonucleotides instead of cytosine leads specifically to hybridization complexes with nucleic acids with homogenous stability. This is useful for the adaptation of the stabilities of different oligonucleotide sequences in all kinds of hybridization techniques, for example in oligomer chip technology.

Title: Data recording method and data recovery method
Inventor: YAMAGUCHI TAKAYOSHI
IPC: G11B27/10
Filed: 2000-10-11
Abstract: In general, time codes recorded on the disk are represented by relative times from the start of video data of each video program. Therefore, when a plurality of video programs have been recorded on one disk, a plurality of video data having identical time codes exist on the disk. In such a case, there is a fear that the data cannot be recovered in the correct order. When a sequence of video or image data is recorded on the recording medium, the sequence is recorded on the recording medium by dividing it into a plurality of units and recording within each unit the information representing the ordinal position on the sequence in which the unit is to be reproduced and the information for providing distinction of a device by which the unit was recorded. With this arrangement, even if there exist on the recording medium some units having information indicating the same ordinal position on each sequence, it is possible to make distinction between the sequences because the device ID unique to each device is allotted to each unit.

Abstract: La présente invention concerne un procédé de production de fonte brute. Selon ce procédé, du minerai de fer est réduit en éponge de fer, dans un arbre de réduction (1), puis cette éponge de fer est introduite dans la tête d'un gazéificateur de fusion (3), dans lequel l'éponge de fer est fondue au moyen d'un agent de gazéification, qui est également introduit dans la tête du gazéificateur de fusion, et d'un gaz contenant de l'oxygène, et est mise en fusion pour donner de la fonte brute liquide, un gaz de réduction étant simultanément produit. Ce gaz de réduction est extrait de la tête du gazéificateur de fusion et est conduit à l'arbre de réduction, afin de réduire l'oxyde de fer. Le fonctionnement du gazéificateur de fusion est commandé de façon qu'un gaz de réduction est produit, avec une telle composition et dans une telle quantité, que l'éponge de fer introduite dans le gazéificateur de fusion présente un haut degré de métallisation. Le fonctionnement du gazéificateur de fusion est également commandé par introduction d'oxyde de fer dans celui-ci, ce qui permet de réduire le degré de métallisation de tous les supports de fer introduits dans le gazéificateur de fusion, par rapport à celui de l'éponge de fer.

Title: Offline code based reloading system
Inventor: ADAMSON RICHARD I C
IPC: G07F7/08
Filed: 2003-05-30
Abstract: An offline code-based reload device and method for adding value to a reconfigurable memory storage means in a portable storage medium. Reload is effected using a reload device not directly connected by telephone or any other communication network to a value supplier. The system uses a "one time use number" ("OTN") generated by a computer program containing an algorithm containing information on the value to be added and a transaction sequence number ("TSN"). Upon presentation of the portable storage medium to the reload device and entry of the OTN into a numeric keypad, the reload device decodes or disassembles the OTN to verify its authenticity, validate that it was created for the specific portable storage medium presented to the reload device and to verify through the TSN that the OTN has not been previously used to add value from the receiving reload device or any other reload device. The reload device further extracts the value from the OTN, adds the value to a selected purse on the portable storage medium and loads a new TSN to the portable storage medium.

Title: Fuel cell separator manufacturing method and fuel cell separator
Inventor: IKEDA TAKENORI
IPC: H01M8/02
Filed: 2003-08-07
Abstract: A fuel cell separator having dense areas and porous areas is manufactured by charging powdered molding material into a compression mold, then compression molding the powdered material. The powdered material is charged respectively for the dense areas of the separator and for the porous areas of the separator, following which the respectively charged molding materials are integrally compression molded to form dense areas and porous areas. This process can be used to inexpensively mass-produce fuel cell separators in which dense areas and porous areas are selectively formed where required. The respective areas can be conferred with a uniform density or porosity even in separators having flow channels of complex shape.
