Title: Method and apparatus for sample and defect removal from a bore
Inventor: REINHART EUGENE R
IPC: B23H9/00
Filed: 1995-07-06
Abstract: A metal section removing tool (10) separates a section of metal from a metal object (M) such as a turbine motor. The tool (10) separates an elongated section of metal from the object using a pivotally mounted cutting device (16) that cuts along a cutting arc ("B") with cutting arc axis ("A") aligned parallel to the longitudinal axis of the cutting device. Preferably, the tool (10) uses electric discharge machining to separate the metal section from the object (M). The tool (10) also includes channels (48, 50) formed in the cutting device (16) for directing the flow of a dielectric fluid to a cutting edge of the cutting device (16). The cutting method includes first securing a carriage at a fixed position with respect to the object and then pivoting the cutting device along the cutting arc ("B") to separate a section of metal from the object (M).

Patent CA-2195771-A1 (CA)
Inventor: GORDON DANIEL A
IPC: G01N21/892
Filed: 1996-06-10
Abstract: Cette invention concerne un appareil de mesure directe de la couleur et des caractéristiques liées à la couleur d'une feuille en mouvement. On effectue les mesures du pouvoir réfléchissant et de l'indice d'opacité de façon à établir des corrections d'opacité pratiquement en temps réel pour un spectre de couleurs complet. Un capteur optique de couleurs, conforme à la présente invention, comporte une paire de spectromètres synchronisés, le premier spectromètre étant aligné de façon à visualiser une région de la feuille doublée d'une matière hautement réfléchissante (dite "blanc") et le second spectromètre étant aligné de façon à visualiser une région de la feuille doublée d'une matière hautement absorbante (dite "noir"). L'utilisation des deux spectromètres permet d'effectuer des mesures pratiquement simultanées de "blanc" et de "noir" pour un spectre de couleurs complet. Le système de détection optique des couleurs comporte également deux sources lumineuses, une lampe éclair et une lampe au tungstène continuellement sous tension. Les faisceaux lumineux des deux sources sont combinés de façon à constituer un troisième faisceau d'éclairage de la feuille de caractéristiques proches d'une source à la norme D65. On régule électroniquement l'intensité de la lampe éclair pour maintenir l'équilibre du rayonnement ultraviolet par rapport à la lumière visible qui caractérise la source normalisée. Le capteur de couleurs comporte en outre un système de doublage des feuilles comportant une roue rotative normalisée portant un pavé blanc normalisé. Dans le capteur selon l'invention, on prévoit également la possibilité de rotation de la roue normalisée ainsi que la normalisation du capteur en position extérieure à la feuille, le pavé blanc étant constamment isolé de l'environnement de la fabrique de papier pendant ladite normalisation. Le système de doublage des feuilles comporte une plaque faisant office de guide pour le papier, ladite plaque définissant un espace annulaire à écoulement tourbillonnaire à l'intérieur duquel l'air est injecté depuis une source sous pression. La zone de basse pression ainsi produite dans ledit espace attire la feuille de papier vers la plaque faisant office de guide. Dans le même temps, l'air de circulation s'échappe en tourbillonnant de l'espace à écoulement tourbillonnaire pour former une fine couche d'air ou un galet soufflant entre la feuille et le guide du papier. On parvient ainsi à minimiser le flottement de la feuille et à empêcher que cette feuille ne soit endommagée.

Inventor: DAVIES DAVID HUW
IPC: H04J11/00
Filed: 1997-03-04
Abstract: A method and apparatus are disclosed for determining the boundaries of guard intervals of data symbols being received in a coded orthogonal frequency division multiplexed signal. Temporal samples separated by an interval of an active interval of a data symbol are associated in pairs, and difference signals obtained. The dispersion of a first comparison block of difference signals is determined, and compared to the dispersion of a second comparison block of difference signals, the second comparison block being displaced from the first comparison block by n samples. An F ratio is calculated for the dispersions of the two blocks. F ratios are iterated in a succession of comparison blocks, and a signal representing the F ratios subjected to peak detection. The peaks represent the boundaries of the symbol's guard interval. This information is utilized in synchronizing an FFT window for subsequent signal reconstruction.

Title: Nozzle for extruding flowable material
Inventor: LEOPOLD EDMUND A
IPC: B29C48/30
Filed: 1994-01-07
Abstract: A glazed unit having three sheets includes a pair of outer glass sheets secured to outer legs of a spacer having a generally U-shaped cross section.  On the base of the spacer between the outer legs is provided a layer of pliable material having a generally U-shaped cross section and having a desiccant therein.  A third or intermediate glass sheet has its edge portion in the groove formed by the layer of pliable material.  Movement of the third sheet toward an outer glass sheet is limited by the cooperation of the layer of the pliable material and portion of the outer legs of the spacer at the corners of the unit bent inwardly to move the layer of pliable material at the corner toward the unit during fabrication of the unit.          A nozzle for depositing the shaped layer of the pliable material includes a platform having a shaping tip. The shaping tip has converging sides at one end and generally parallel sides at the other end.  The portion of the tip at the first end has a lower elevation than the portion of the tip at the second end.  Holes for moving the pliable material are provided in the platform on each side of the tip and in tips intermediate its ends.  The different elevation and converging end minimizes if not eliminates tailing.          A method is also discussed for making the triple glazed unit using the nozzling to provide the shaped layer of pliable material.  An injector arrangement fills the unit with an insulating gas e.g. Argon.

Patent CA-2222728-A1 (CA)
Inventor: SMITH EDWARD PETER
IPC: F16L55/162
Filed: 1996-06-20
Abstract: A method and apparatus are provided for forming sealed and reinforced holes through the end of a flexible resin impregnable tubular pipe liner (21) for securing a cable (73) thereto and for sealing the end of the liner. The liner is to be installed into an existing conduit either by pulling the liner into the conduit using a cable secured to holes (27) at the front end of the liner or by eversion of the liner while securing a hold-back cable to holes at the trailing end of the everting liner. First, the holes are cut through the liner, and then resin is impregnated into the region about each hole and hardened to form an integral grommet or reinforcement about the hole. A mold for impregnating the region about the hole includes a lower mold body with a projecting spigot and a groove thereabout. An upper mold body has a central opening with a groove thereabout, the upper mold body fitting over the spigot but leaving room to engage a tube therebetween. A tube fits into the central opening and receives a resin within it. The resin is forced by a plunger down the tube, about the spigot and into the region surrounding the hole in the liner. After injection, the resin is allowed to harden, thereby forming a secure and reinforced hole for attaching a pull-in or hold-back rope or cable.  The liner can be folded at the end, and reinforcing disks can be placed on the outsides of the folded liner in order to distribute the pulling forces along the material. Also, a capstan can be attached to the integrally-formed grommets between the two folded sides of the liner end portion in order to allow the hold-back cable to be wrapped around it so that, when one end of the cable is fixed, the other end of the cable can be slackened to allow the liner to evert slowly within a conduit.
