IPC: B23K26/06
Filed: 1998-01-21
Abstract: A method for producing a laminated object repeats a depositing step and an irradiating step alternatively. The irradiating step comprises the operations of: covering a deposited layer with a mask having a pattern configuration for penetrating the laser beam; and scanning the laser beam on the deposited layer covered with the mask in such a manner that the laser beam depicts an irradiated continuous wave trace being wider than the pattern configuration of the mask, by moving the laser beam in the Y-direction with a Y-- rotating mirror, while repeating oscillations of the laser beam in the X- direction with a X--rotating mirror. The laminated object may be a casting mold.

Inventor: KRAMER TOM
IPC: A61B1/303
Filed: 1996-10-01
Abstract: A method and apparatus are provided for imaging a narrow body lumen (16), the method comprising maintaining separation between a distal end (20) of an optical viewing scope (14) and a lumen wall (16) with a spacing structure (74) which extends distally from the distal end of an access catheter (72).  Optional spacing structures include distal cages (74) and a guidewire (122) which is fixed to and extends distally from the access catheter body. The invention is beneficial during retrograde imaging of the fallopian tube, and also allows antigrade imaging and advancing the access catheter and scope under the direction of the image provided, as it prevents the tubal wall from coming into such close proximity to a falloposcope as to produce "white-out"  on the imaging monitor.

Patent CA-2243803-A1 (CA)
Inventor: FLOWER RONALD J
IPC: H02J7/00
Filed: 1998-07-23
Abstract: La présente invention a pour objet un circuit permettant de produire une augmentation de tension dans une batterie comportant une pluralité de cellules montées en série. Le circuit en question conduit une ou plusieurs des cellules à se décharger à travers une résistance à un régime plus élevé que celui des autres cellules, ce qui a pour effet de produire une augmentation de tension lorsque la cellule à régime plus rapide se décharge complètement avant les autres. Une diode à polarisation inverse connectée en parallèle à la cellule à régime de décharge plus rapide amène le courant à contourner la cellule en question lorsque complètement déchargée, ce qui prévient le risque de charge inverse. Le circuit en question permet de régler l'intensité du régime de décharge plus élevé et de déterminer, par le fait même, le moment où se produira l'augmentation de tension.

Title: System for producing high density, extra large well perforations
Inventor: GEORGE KEVIN R
IPC: E21B43/117
Filed: 1997-02-13
Abstract: A shaped charge (27) and liner (33) having a minimum outside diameter determined by the formula: DL = 2.625 - 0.3571 (6-DID), where DL = Liner Minimum Outside Diameter, DID = Carrier Inside Diameter. The geometry of the shaped charge (27) reduces the chances of interference between charges by controlling burn time, as does the positioning of the primer cord. The liner (33) has an open end with a minimum outside diameter determined by the formula. The shape of the case (29) and liner (33) is determined by keeping the center of the primer cord (49) a distance not greater than 0.10 (DID) from the center line of the carrier (13), ideally not greater than 0.05 (DID). This yields a large diameter, flat shaped charge that may be loaded in a tubular carrier having a charge or perforation density of at least 10 shots per foot.

Patent CA-2253191-A1 (CA)
Inventor: REINHARDT BERND
IPC: D21H19/14
Filed: 1997-04-18
Abstract: The invention concerns a process for thermo-mechanical surface treatment of webs, particularly paper and cardboard webs, and means to carry out the process. According to the claimed process, the adhesion between the web and the surface of the tool used for the thermo-mechanical surface treatment, e.g.  a roller or press, is reduced or eliminated by the application of an abhesive agent containing dicarboxylic acid esters-dialkylesters and/or esters of saturated and/or unsaturated C8-C18 fatty acids with multivalent alkanols with 3 to 6 carbon atoms and/or single or multiple unsaturated C16-C12 fatty acids as abhesive components. The preferred use of abhesive agent is in the form of an oil-in-water emulsion which is either applied to the surface of the tool used for the thermo-mechanical treatment or added to the impregnating liquid, paper-coating mass, fountain solution or the steam for pre-moisturising, or is applied to the paper web after the impregnating stage, or directly in front of the glazing roller. Steam-volatile abhesive agents are preferred and are metered into the steam moistening process via the steam line.

Patent CA-2257590-A1 (CA)
Title: Banknote reader system
Inventor: DAVEY JOHN C
IPC: G07D7/12
Filed: 1998-12-29
Abstract: A portable banknote reader for use by blind individuals is adapted to receive a banknote. The reader audibly or by other means announces the denomination of the note. The reader requires currency which is coded with special code markings. In order to read the note, the reader transmits infrared (IR) light through the note from one side and senses the intensity of light passing through the note on the other side. The reader converts intensity readings into a series of signals representative of the presence or absence of codes on the note, compares the series of signals against known codes to determine the denomination of the note and then activates a voice synthesizer or other device to output the denomination. The portable reader is more compact, less expensive and more reliable than current readers, is easy to use by blind people, requires little maintenance and has an expected life of more than 10 years.

Filed: 1997-07-11
Abstract: Machine à réluctance commutée capable de fonctionner correctement dans des conditions anormales; elle inclut un contrôleur, qui réagit à la défaillance d'un enroulement de phases en coupant le courant d'alimentation des enroulements de phases de tous les pôles du stator qui sont alignés sur un pôle du rotor au moment où le pôle du stator abritant l'enroulement de phases défectueux s'aligne sur un pôle du rotor. Par conséquent, pendant ledit moment, il n'y pas de flux magnétique ni dans le stator, ni dans le rotor; partant, il n'y a pas de courant induit dans l'enroulement de phases défectueux. Le système décrit permet d'éviter l'apparition d'un couple de réaction et d'exclure la possibilité d'une panne catastrophique de la machine SRM.
Patent CA-2263272-A1 (CA)
Title: Chargement de blocs de peinture solides sur une bande d'acier glissant en continu
Inventor: HORTON TREVOR JAMES
IPC: B05C3/18
Filed: 1997-08-28
Abstract: En règle générale, on produit une bande d'acier pré-peinte dans un laminoir finisseur d'acier en appliquant à l'état de liquide de fusion exempt de solvant sur un substrat de bande d'acier chaud, selon un procédé appelé dépôt par fusion. On obtient un taux de dépôt par fusion en régulant la pression de contact entre la peinture solide et le substrat de bande d'acier chaud, tout en maintenant constants tous les autres paramètres intervenant dans le taux de dépôt. De la difficulté de réguler avec précision tous ces paramètres découle, à son tour, la difficulté d'obtenir un taux de dépôt systématiquement bas et constant pendant la production de couches de peinture minces d'épaisseur uniforme. On a surmonté ce problème en chargeant un corps solide de peinture sur un transporteur à toile sans fin (9) comprenant une raclette de courroie sensiblement plane (11), une poulie de la tête (12) et un mécanisme de retour adjacent au point de contact du block de peinture (15) et à la bande d'acier en mouvement (5). Ledit transporteur comprend aussi un guide à poste fixe (13) et une poulie de renvoi (14). Le mécanisme de retour est construit de telle sorte que la direction du mouvement de courroie au retour est au moins parallèle à celle de la bande en mouvement continu (5), et, de préférence, à un angle éloigné de celle-ci. La poulie de la tête (12) est, de préférence, enduite d'un matériau à coefficient de friction élevé tel que le caoutchouc naturel. La raclette de courroie plane (11) est conçue pour porter une charge d'au moins un bloc, mais de préférence deux blocks (15), d'une composition de peinture exempte de solvant qui vient se lier au matériau souple, durable et réfractaire de la courroie. Dans sa forme la plus simple, la raclette plane (11) peut glisser sur une table d'appui, le guide à poste fixe du mécanisme de retour formant le bord de la table. Dans une forme d'exécution différente, les blocs de peinture (15) peuvent être chargés verticalement vers le bas entre deux transporteurs à courroie se déplaçant dans des directions opposées l'une par rapport à l'autre.
