Title: Appareil de prospection geophysique passif et procede utilisant une association entre detection de discontinuites et champs electromagnetiques tres basse frequence
Inventor: JACKSON JOHN R
IPC: G01V3/08
Filed: 1997-07-23
Abstract: L'invention porte sur un appareil et un procédé de détermination passive de la profondeur et de l'épaisseur d'une formation géologique souterraine comprenant des hydrocarbures tels que du pétrole et/ou du gaz, ou des dépôts de minerais présentant une valeur commerciale tels que des métaux précieux. L'appareil comporte une antenne pour capter les signaux de très basse fréquence émanant naturellement de la surface de la Terre. Selon une réalisation préférée, le signal reçu est amplifié et filtré. Le signal est ensuite modulé sur une onde porteuse. Le signal modulé est ensuite filtré pour éliminer l'une des bandes latérales, par exemple, la bande inférieure. Un oscillateur génère une fréquence d'accord qui est comparée au signal modulé, filtré de façon à s'accorder à une fréquence donnée. L'oscillateur balaye toute la plage de fréquences telle que la partie de la bande latérale supérieure du signal filtré, modulé. Pour chaque fréquence désirée de cette plage qui correspond à une certaine profondeur de la Terre, le signal accordé est ajusté à la fréquence désirée et envoyé à un détecteur de niveau de tension qui détecte les informations accordées et les convertit en impulsions. Les impulsions sont comptées sur une durée souhaitée pour déterminer la densité des impulsions, c.-à-d. le nombre d'impulsions par unité de temps. Un compteur peut être utilisé et réglé comme déclencheur pour émettre un signal de sortie lorsqu'un nombre spécifique d'impulsions par unité de temps est réalisé. Il est possible d'afficher, d'enregistrer et/ou d'envoyer à un ordinateur les impulsions ou le signal de sortie et de les manipuler ultérieurement en faisant varier l'unité spécifique de temps, c.-à-d. le laps de temps, pour examiner les informations de densité d'impulsions.

Title: Acrylate coating methods
Inventor: LANGLOIS MARC
IPC: H05H1/24
Filed: 1997-10-31
Abstract: Material such as polypropylene, polyester or nylon, with high oxygen barrier properties is prepared by evaporating polyfunctional acrylate monomer with flash evaporators (43, 47, 49) and condensing the acrylate as a monomer film or by roll coating acrylate monomers onto a plastic sheet (38) in a vacuum chamber (36), using reels (37, 41). Acrylate is polymerized by irradiation by ultraviolet or electron beam (44, 48, 51, 53). A layer of metal or oxide oxygen barrier material is vapor deposited (46) over the first layer of cross-linked acrylate. An acrylate layer is applied over the metal layer. Adhesion of the acrylate layer on the plastic sheet is enhanced by reactive plasma treatment (52) of the surface immediately before deposition, the plasma treatment and coating being conducted in vacuum with less than three seconds between them. Condensation efficiency is enhanced by chilling the surface of the substrate on which the acrylate is condensed to temperatures below 0 ~C. A  backing drum (39, 40) and/or rolls (42) may be cooled to less than -15 ~C.

Title: Method and apparatus for printing onto a continuously advancing web of work material
Inventor: STEIN DARRYL COLBURN
IPC: B41J19/14
Filed: 1999-10-04
Abstract: In an apparatus (20, 320) for printing on a web of work material (26, 326) continuously advanced in an X coordinate direction at a velocity v wx, at least one print head (86, 286) having a plurality of print elements (100) arranged in a scanning array (102, 302) extending in the X direction is repetitively movable relative to the apparatus (20, 320). The scanning array (102, 302) moves at a velocity v a along a path that includes at least one scan segment and at least one repositioning segment. As the scanning array (102, 302) traverses the scan segment it has a first velocity component v ax in the X direction, and a second velocity component v ay in a Y direction perpendicular to the X direction. The first velocity component v ax is equal to the velocity v ax so that the scanning array (102, 302) in traversing the scan segment, scans a swath on the web (26, 326) parallel to the Y direction, having a swath height hs. The velocity component v ay is such that in the time taken for the array (102, 302) to move along the full extent of the scan segment the web (26, 326) advances a distance h w in the X direction that is less than h s. The array (102, 302) then travels along the repositioning segment such that prior or equal to a time taken for the web (26, 326) to advance a distance d= h s- h w the print head (86, 286) is positioned for movement along the scan segment, thereby causing successive swaths of the web scanned by the array to be positioned immediately adjacent to one another.

Patent CA-2286661-A1 (CA)
Inventor: KELLY N PATRICK
IPC: H04L12/10
Filed: 1998-04-07
Abstract: A Physical Layer Device is disclosed having power savings features operable during autonegotiation for multiple technologies. Excessive power consumption is alleviated by decreasing the power required by the receiver(s) during parallel detection. The Physical Layer Device includes at least one port, with each port including a parallel detection receiver for receiving data and messages from a connected device, the data and messages including autonegotiation fast link pulses indicating a technology capability of the connected device, a cycler for enabling the parallel detection receiver for a fraction of an autonegotiation period and a controller for controlling the cycler. The enabling of the receiver for each port, whether a multiple or single port device, is staggered to prevent more than one receiver from being enabled at one time. Accordingly, the receivers are enabled for a brief period of time to check for the presence of the required signals, and then disabled for a much greater period of time before being enabled again. Further, the Physical Layer Devices contain multiple ports that can stagger the enabling of their receivers so that only one port's receiver is active at any given time.
