Patent CA-2267209-A1 (CA)
Inventor: SUGIKAWA HIROFUMI
IPC: H01M4/64
Filed: 1997-10-03
Abstract: A battery electrode substrate is fabricated by the steps of: applying a pressing force to a thin metal sheet by embossing to form an undulated portion over the entire surface; during the process of forming the undulated portion, forming holes in the apices of the undulated portion by a pressing force;  producing burrs protruding outwardly from the edges of the holes; stacking the metal sheets formed with the undulated portions to combine the burr on the apex side of the raised portion of the lower layer of the adjoining metal sheets with the burr on the apex side of the recessed portion of the upper layer. This structure allows an active substance to be filled into a space formed between the upper and lower adjoining metal sheets through openings of the apices of the recessed and raised portions.

Patent CA-2278031-A1 (CA)
Inventor: TAM ROBERT
IPC: C12Q1/00
Filed: 1997-12-19
Abstract: L'invention concerne des oligonucléotides d'aptamères qui se lient au site de liaison de l'ADN de protéines comme la protéine Sp1 ou les protéines apparentées, ces protéines permettant de réguler les gènes qui codent les molécules co-stimulantes telles que la molécule CD28, et les cytokines telles que IL-2 et GMCSF. Les oligonucléotides entrent en compétition avec les sites de liaison de l'ADN des protéines régulatrices qui régulent spécifiquement les molécules afin de moduler l'activation des lymphocytes T. On module ainsi l'expression génique en empêchant la transcription du gène. Les aptamères sont administrés de manière à constituer une thérapie contre les maladies impliquant une activation aberrante des lymphocytes T, par exemple le psoriasis, le diabète sucré de Type I (insulinodépendant), la sclérose en plaques, l'uvéite auto-immune, la polyarthrite rhumatoïde, le lupus érythémateux aigu disséminé, les infections inflammatoires touchant le tube digestif (maladie de Crohn et colite ulcéreuse), ainsi que les chocs septiques. L'administration des aptamères permet de réguler l'activation normale des lymphocytes T, par exemple lors d'un rejet de greffe allogénique.

Patent CA-2294307-A1 (CA)
Inventor: CANTU ROBERT J
IPC: B01D21/26
Filed: 1998-06-22
Abstract: Blood processing systems and methods are disclosed. A processing chamber (14) rotating on a rotating element includes a first compartment (38) and a second compartment (40). Blood is conveyed into the first compartment (38) for centrifugal separation into components. A liquid free of blood occupies the second compartment (40) to counter-balance the first compartment (38) during rotation on the rotating element. In one embodiment, the second compartment (40) is served by a single fluid access. Prior to use, the single access is coupled to tubing, through which a vacuum is drawn to remove air from the second compartment (40). While vacuum exists, communication is opened between the tubing and a source of liquid. The vacuum draws the liquid into the second compartment (40) through the single access, thereby priming the second compartment (40) for use.

Title: Procede et dispositif pour des operations effectuees avec un tube de production enroule
Inventor: SOLA KJELL INGE
IPC: E21B19/22
Filed: 1998-06-10
Abstract: Procédé mis en application dans des opérations effectuées avec un tube de production pouvant être enroulé, telles que des opérations de forage à terre et en mer de pétrole et de gaz, pour lesquelles on utilise ce type de tube de production (34). Ce tube de production (34) est enroulé sur un tambour (36) et déroulé au moyen d'un injecteur de chargement et de déchargement (32), ledit tambour (36) pouvant effectuer une rotation sur son axe. Dans le but de permettre au tube de production (34) de tourner à l'intérieur du puits, de manière à mettre en rotation la pièce de transition inclinée portant le trépan, afin de pouvoir effectuer le forage le long d'une trajectoire prédéterminée sans utiliser d'outil d'orientation en fond de trou, on imprime au tube de production (34) des déplacements rotatifs pendant sa progression vers l'avant. On peut, à cet effet, placer le tambour (36) et l'injecteur (32) placé sous le tambour sur une table rotative (30) dont l'axe vertical de rotation (A-A) est aligné sur l'axe vertical de symétrie d'un dispositif de sécurité (28) placé en position inférieure. Le tambour (36) permettant d'enrouler le tube de production (34) est, de préférence, positionné de façon excentrique sur la table rotative (30). Les déplacements rotatifs de progression vers l'avant du tube de production (34) permettent également de limiter considérablement la friction à l'intérieur du trou de sondage, ce qui provoque une augmentation de la charge pesant sur le trépan et, par conséquent, de la vitesse de forage et prolonge la longueur du trou horizontal.

Title: E-mail type facsimile apparatus and e-mail reception method
Inventor: SAITO KYOJI
IPC: H04L12/58
Filed: 1998-10-07
Abstract: The decision unit leaves unacceptable mail in the mail server and stores the left mail number and message ID of the latest mail in the 1st RAM as left mail number K and left mail ID, respectively. In the next access, the decision unit acquires the message ID of the Kth mail stored in the mail server and compares it with the left mail ID. If both match, the "K+1"th and subsequent pieces of mail are received. Therefore, it distinguishes the left mail and new incoming mail, avoiding repeated reception of the left mail. This makes it possible to leave E-mail in the mail server using it as a secondary storage device and distinguish the left E-mail and new incoming E-mail in subsequent accesses.
