Title: Mecanismes de reglage et nettoyage pour machine de retrait par compression
Inventor: HUGHES ROBERT J
IPC: D06C21/00
Filed: 1996-09-13
Granted: 2002-07-23
Abstract: Machine de retrait par compression mécanique, conçue notamment pour des tricots tubulaires et au large. Cette machine comprend des cylindres d'alimentation (11) et de retardement (12) qui coopèrent avec des lames côté entrée (18) et côté sortie (35), formant une zone de retrait par compression entre les cylindres; la machine est également pourvue de nouveaux mécanismes de réglage améliorés. Chacune des lames est pourvue d'un mécanisme de réglage séparé qui comprend, de chaque côté de la machine, un vérin pneumatique en ligne (50, 70), un système de réglage indépendant accessible par un technicien, et un excentrique rotatif (54, 74). Les excentriques rotatifs sont supportés de chaque côté par un arbre commun (55, 75) qui est accessible de l'extérieur et qui constitue un système de réglage commandé par un opérateur. Du fait de la conception des parties excentriques de l'arbre, les limites de contrôle de la production par l'opérateur se situent dans une plage de sécurité afin d'éviter que l'équipement soit endommagé dans le cas d'une intervention maladroite de l'opérateur. Les vérins pneumatiques en ligne, incorporés dans le mécanisme de réglage, permettent le déplacement global, rapide, des éléments en vue de reconfigurer la machine dans un état d'ouverture totale afin de procéder à son nettoyage.

Title: A method for manufacturing an orifice plate for use of a liquid discharge, an orifice plate, a liquid discharge provided with such orifice plate, and a method for manufacturing such liquid discharge
Inventor: KASHINO TOSHIO
IPC: B41J2/05
Filed: 1998-07-02
Granted: 2003-09-16
Abstract: A method for manufacturing an orifice plate used for a liquid discharge provided with discharge port for discharging liquid comprises the steps of preparing a non-conductive plate having recessed portion formed on the circumference of the flat portion corresponding to the discharge port, forming a first conductive material peelable from the non-conductive plate only in the recessed portion of the non-conductive plate, forming a plate member by plating the first conductive material with a second conductive material by electroforming method after the formation of the first conductive material, and obtaining the orifice plate having the discharge port by peeling off the plate member from the non-conductive plate.  With the method thus arranged, it is possible to materialize the same precision as in the glass mask used for photolithography, and make the variation of orifice areas smaller for the formation of highly densified orifices.

Patent CA-2246835-C (CA)
Inventor: MCNEIL MICHAEL
IPC: B60T13/66
Filed: 1998-09-08
Granted: 2001-11-20
Abstract: The present invention is a valve system for exhausting air from a brakepipe in a remote portion of a train. It has a pressure containment structure having a cylindrical bore and a piston mounted in the bore. A first valve chamber is on one side of the piston and a second valve chamber on a second side.     A diaphragm seals between piston and bore, the diaphragm having an annular fold for permitting movement of the piston within the bore. The system has a first brakekpipe pressure passageway for conveying air from the brakepipe to the first valve chamber and a control pressure connection for conveying air from a control chamber to the second valve chamber. A biasing means is provided for urging the piston toward the first valve chamber. A brakepipe exhaust valve connected to the piston is closed when the piston is moved toward the first valve chamber and opened when the piston is moved toward the second valve chamber so that when the pressure in the control chamber is reduced the brakepipe exhaust valve is opened and air is vented from the brakepipe. An annular sleeve is attached to the pressure containment structure and protrudes into the fold of the diaphragm to prevent the diaphragm from inverting if the pressure in the brakepipe drops below the pressure in the control chamber when the piston is positioned toward the first valve chamber.

Patent CA-2263333-C (CA)
Inventor: JAFFE STEPHEN M
IPC: H05H1/42
Filed: 1997-09-26
Granted: 2004-03-30
Abstract: A plasma jet CVD system (100) includes gas injectors (122a-122h) and a stand-off ring (126). The gas injectors have outlet holes (236a-h) preferably flared to approach the expansion angle of the injected jet, thereby keeping the holes substantially free from entrained atomic hydrogen. The injectors are arranged counter-rotational to the swirl of the primary jet, providing a more uniform mixture of hydrocarbons and atomic hydrogen. The stand-off ring provides vents (152a-152d) for cooler gases to enter the nozzle (128), thereby decreasing the overall temperature of the injectors and decreasing the temperature gradient experienced by the injectors, thereby preventing injector cracking. In addition the vents reduce shear, thereby increasing jet velocity and increasing the deposition rate for the coating. In addition, a new method of injector design permits optimal mixing characteristics to be obtained across various recipes whereby the ratio of the mass flux of the primary flow of the jet to the mass flux of the injected flow from the downstream injectors is kept constant.

Title: Systeme et procede de generation de valeurs de pixels
Inventor: GRABENSTEIN MARTIN
IPC: G06T15/50
Filed: 1998-06-23
Granted: 2007-05-01
Abstract: La présente invention concerne un système infographique permettant de générer des valeurs de pixels pour les pixels d'une image d'objets d'une scène. On utilise pour cela des séquences strictement déterministes faiblement déviantes, telles que des séquences de Halton. Ces séquences servent de points échantillons permettant d'évaluer des intégrales simulant différentes techniques infographiques, et notamment: (1) les ombres douces des scènes éclairées par une source lumineuse finie telle qu'un disque, par opposition à une source lumineuse ponctuelle; (2) la simulation de la profondeur de champ; (3) le flou du mouvement; (4) le scintillement; et (5) l'éclairage global. Le système infographique utilise la séquence faiblement déviante: (1) en relation avec l'ombre douce pour générer des points échantillons dans l'espace fini de la source lumineuse éclairant la scène; (2) en relation avec la simulation de la profondeur de champ, pour générer des points échantillons occupant la zone lenticulaire entre la scène et l'image; (3) en relation avec le flou du mouvement, pour générer des points échantillon prenant un intervalle de temps pendant lequel on veut simuler le flou du mouvement correspondant aux objets en mouvement dans la scène; (4) en relation avec le scintillement, pour générer des points échantillons à scintillement dans une image ou une pluralité de pixels contigus; et (5) en relation avec le scintillement, pour générer des points échantillons destinés à une utilisation selon un principe strictement déterministe de roulette russe de façon à générer des estimateurs destinés à l'utilisation dans la simulation d'éclairage global. A la différence de ce qui se produit dans le cas de la technique du Monte-Carlo utilisant des nombres aléatoires, les séquences faiblement déviantes garantissent que les points échantillons sont régulièrement répartis dans une région considérée ou un intervalle de temps défini, ce qui vient réduire les erreurs affectant l'image par suite de l'agglutination de tels points échantillons. En l'occurrence, l'invention facilite la génération d'image de qualité améliorée, et ce, en utilisant le même nombre de points échantillons, pour le même effort informatique, que dans le cas de la technique du Monte-Carlo.
