Title: Monture de la lame dans la section de formation d'une machine a deux toiles
Inventor: MCPHERSON DOUGLAS R
IPC: D21F1/52
Filed: 2000-11-15
Abstract: L'invention porte sur une monture flexible de la lame dans la section de formation d'une machine à papier à deux toiles comportant essentiellement une embase (1), reposant sur la structure (2) de la machine, à laquelle est fixé une plaque flexible en C (3). L'une (4) des extrémités se la plaque flexible en C (3) est fixée à l'embase (1), et l'autre au support (8) d'une lame (13) en contact avec la toile. Un tube (14) sous pression de mise en charge est placé sous la plaque en C (3) entre l'embase et sa deuxième extrémité. Le tube (14) en se chargeant fait fléchir la plaque (3) et met en un premier temps la lame (13) en contact avec l'une des toiles. Lorsque la charge augmente, la face (22) de contact de la lame (13) contacte plus fortement la toile. Dans une exécution préférée, l'angle d'enveloppement de la toile autour du bord d'attaque de la lame peut être réduit, la monture permet ainsi de diminuer l'usure de la toile passant sur la lame. La monture permet également des flexions de la lame pour tenir compte de variations ponctuelles telles que l'épaisseur de pâte. La monture peut également comprendre des évents (81) d'évacuation en aval de la lame du liquide accumulé en amont de la lame.

Title: Soudures et brasures à point de fusion variable
Inventor: CORBIN STEPHEN F
IPC: B23K35/14
Filed: 2001-05-24
Abstract: L'invention concerne des soudures et des brasures à point de fusion variable, composées d'une poudre métallique ou d'une poudre d'alliage métallique présentant un point de fusion bas associé à une poudre métallique présentant un point de fusion plus élevé. Lors du chauffage, un alliage se forme in-situ entre les poudres métalliques à point de fusion bas et à point de fusion élevé, de sorte qu'une solidification se produit à la température de soudure ou de brasage, créant une nouvelle température de solidus (ou de fusion) plus élevée, la formation de composés intermétalliques étant faible ou nulle. Un aspect de l'invention concerne une soudure comprenant de la poudre de Sn mélangée à une poudre Sn-Bi eutectique dont la composition est 63 % en poids de Sn: 57 % en poids Bi, la proportion globale de Bi dans la composition étant de 3 % en poids. Cette composition présente un point de fusion initial de 140 °C et une seconde température de fusion de 220 °C après avoir été chauffée pour former un alliage in-situ. Un autre aspect concerne une composition de poudre de Pb mélangée à une poudre eutectique Pb-Sn, qui comprend 62 % en poids de Sn:58 % en poids de Pb, la proportion globale de Sn du mélange étant égale à 15 % en poids. Cette composition présente un point de fusion initial de 183 °C et une deuxième température de fusion de 250 °C.

Title: Moteur d'aspiration pour aspirateur
Inventor: CUNNINGHAM JAMES VERN
IPC: A47L5/22
Filed: 2003-03-12
Abstract: Selon cette invention, un aspirateur (1) comprend un moteur (15) à courant continu sans balai comportant un stator (203) et un rotor (212). Le stator est monté sur un arbre et le rotor est monté sur un corps tubulaire (207), à l'intérieur de celui-ci, autour du stator (203). Une roue (17) est montée sur le corps tubulaire (207), à l'extérieur de celui-ci. Le moteur (15) et la roue (17) sont montés dans un logement pourvu d'un orifice d'admission (7) et d'un orifice d'évacuation (9). Le fonctionnement du moteur et la rotation de la roue génèrent un vide partiel au niveau de l'orifice d'admission (7) de sorte que de l'air soit aspiré. L'air est ensuite évacué par l'orifice d'évacuation (9). Un filtre (61) empêche les particules de pénétrer dans le moteur (15). Ces particules sont recueillies dans un compartiment (5) situé en amont du filtre (61). La roue (17) peut être un ventilateur à cage d'écureuil, un ventilateur à ailettes ou un ventilateur centrifuge. Un deuxième orifice d'évacuation (11) expulse les particules du filtre (61) et/ou du compartiment (5) par la rotation de la roue (17) dans le sens inverse ou au moyen d'un second moteur à courant continu et d'une seconde roue. Le logement (2) peut être placé dans une cavité située entre des montants de cloisons classiques.

Title: Linear-and-angular measuring plane mirror interferometer
Inventor: BOCKMAN JOHN J
IPC: G01B9/02
Filed: 1990-01-11
Abstract: A linear-and-angular measuring plane mirror interferometer measures two degrees of freedom, both linear translation and rotation angle, using a single interferometer optical assembly. In alternate orientations it can be used to measure either the pitch, roll or yaw angle. The linear-and-angular measuring interferometer splits the measurement beam at the interferometer optic, using a single integrated optical assembly to make measurements at two locations on a measuring mirror on a stage. In a first embodiment, the input beam is split, and two separate measurements, X and X', are made at two locations separated by a distance d. A second embodiment optically produces a direct measurement of X-X' at a detector. The input beam makes one interferometer measurement for X, then the polarization of part of the resulting output beam is rotated and the rotated part of the beam is returned for a second pass to make an interferometer measurement at a location offset by a distance d from the first pass measurement.

Abstract: \                   ABSTRACT OF THE DISCLOSURE            A tendon for prestressed concrete structure includes a core member such as a steel wire, a steel strand or a steel bar; and an unset bonding material coating the core structure to a predetermined thickness, having a specific setting time determined by selectively determining the respective contents of the bonding material and which sets at an ordinary temperature by chemical reaction; and a seamless corrugated sheath with a long span.  The tendon is manufactured continuously by coating a wire strand core member with an unset bonding adhesive, melt extruding and shrinking a seamless plastic sheath around the coated core member, deforming the plastic sheath to a corrugated shape with the depth of an indented portion being deeper than the thickness of the plastic forming the sheath and cooling the tendon.  The tendon with a long span is wound on the reel for storage, paid off from the reel and cut to the predetermined length, and anchorages are attached to the end of each reel.  The tendon is arranged in a desired arrangement for forming a prestressed concrete structure, concrete is placed so as to bury the tendons therein, and then the tendons are tensioned and fixed after the strength of the deposited concrete has increased to a degree to permit tensioning the tendons and before the unset bonding material sets.  Thus, the unset bonding material sets after the tendons have been tensioned and bonds the tendons firmly to the prestressed concrete structure.

Patent CA-2043598-A1 (CA)
IPC: H04M11/00
Filed: 1991-05-30
Abstract: This invention relates to a method and apparatus for accessing customer meters and for controlling customer devices over a telephone line. A suppressed ringing connection is established over a customer line between a central office and customer station equipment. The connection is between a data accessing device such as a meter reading controller and a customer premises device such as a meter interface unit. Signals are exchanged over the connection between these two units without alerting the customer via a ringing signal and without changing the supervisory state of the customer's station equipment from on-hook. The connection can also be used for controlling devices such as air conditioning units, in order, for example, to avoid overloads in a power distribution system. The voice switching network of the central office is used for making the connection between the meter control unit and the meter interface unit. Advantageously, this arrangement can allow a large number of utility meters and controlling devices to be accessed remotely using existing telephone plant.
