Patent CA-2396763-C (CA)
Title: Touchscreen having multiple parallel connections to each electrode in a series resistor chain on the periphery of the touch area
Inventor: AROYAN JAMES L
IPC: G06F3/041
Filed: 2001-10-16
Granted: 2011-06-07
Abstract: A resistive or capacitive position touchscreen includes a glass substrate having a uniform resistive coating and series resistive chains of overlapping discrete electrodes adjacent to the peripheral edges of the substrate. Gaps in an otherwise insulating linear discontinuity running parallel to each chain form resistive current paths across the touch area. There are at leat two gaps for each electrode so that multiple current paths connect to each electrode. Each gap produces a local ripple in the voltage field which decays away with distance from the gap. Since the ripple decay length is determined by the distance between current paths, the magnitude of the ripple near the electrodes is reduced exponentially by a factor corresponding to the number of gaps per electrode.

Title: Assemblage d'electrode par soudage thermique
Inventor: DIEHL GREGORY W
IPC: B23K9/24
Filed: 2002-08-12
Granted: 2009-02-17
Abstract: Le présent extrait concerne une électrode pour supporter un arc dans un chalumeau à arc de plasma, et qui comprend un élément émissif pour supporter l'arc, qui peut être formé d'hafnium; un élément relativement non émissif comprenant un premier métal contenant de l'argent, qui est positionné pour limiter une surface avant de l'élément émissif, et un support métallique pour maintenir l'élément non émissif. Dans une configuration, le support est en une pièce faite d'un alliage de cuivre comprenant une majeure partie de cuivre et une partie moindre d'un autre métal, tel que le nickel. Après assemblage, l'électrode est soumise à un traitement thermique qui provoque un soudage thermique entre l'élément relativement non émissif et le support métallique, qui, pendant le fonctionnement ultérieur de l'électrode, donne une bonne conduction thermique à l'écart de l'élément émissif et améliore la durée de vie de l'électrode. Avantageusement, pendant l'opération de chauffage, le nickel atténue la réaction eutectique entre le cuivre et l'argent qui se produirait autrement, et permet la soudage sur une large plage de températures et de durées de cycle de chauffage. De plus, la température à laquelle se produit le soudage entre l'élément non émissif et le support est également remontée. En conséquence, si c'est désiré, un soudage thermique peut également être formé entre l'élément émissif en hafnium et l'élément non émissif pendant un même cycle de chauffage, encourageant ainsi une conductivité supplémentaire de l'électrode. Dans des configurations alternatives, d'autres métaux et d'autres configurations, telles que l'utilisation de placage intermédiaire, de la poudre ou un manchon sont utilisés pour faire monter et donner une plus grande plage, pour les températures au-dessus desquelles se produit le soudage entre l'élément non émissif et le support.

Abstract: L'invention concerne un ensemble de levage exempt d'air relativement léger pour système d'arbre/suspension de semi-remorque pouvant passer d'une utilisation autoroutière à une utilisation ferroviaire, utilisant un ressort de torsion hélicoïdal orienté transversalement dont la raideur est relativement faible. Ledit ressort de torsion est emprisonné entre une plaque fixe et une plaque rotative. Une liaison flexible est fixée pivotante au niveau de son extrémité supérieure à la plaque rotative et au niveau de son extrémité inférieure à l'arbre. Cet ensemble produit un bras de couple à vitesse variable et un système de levier augmentant de manière continue, lorsque le ressort pneumatique est trop gonflé, afin d'abaisser ledit système en vue de déplacer la remorque du tracteur autoroutier vers un bogie ferroviaire, ce qui permet d'utiliser un ressort pneumatique moins robuste. L'ensemble crée réciproquement une réduction de l'effet de levier au niveau de la position soulevée de déplacement sur rail, de manière à maintenir fixement le système arbre/suspension en position rail. Lorsqu'on l'utilise pour le transport autoroutier, l'ensemble de levage produit un amortissement sans avoir recours à des absorbeurs de choc.

Title: Amortisseur a friction
Inventor: DEC ANDRZEJ
IPC: F16H7/12
Filed: 2002-09-09
Granted: 2008-12-02
Abstract: L'invention concerne un amortisseur à friction. Cet amortisseur comprend un cylindre intérieur (208) coulissant à l'intérieur d'un boîtier extérieur (201). Un ressort sollicite (202) le cylindre intérieur dans un sens axial opposé au boîtier extérieur. Un premier élément de cale (209) entre en prise de manière solidaire avec un second élément de cale (204). Ce premier élément de cale entre en prise par friction avec le cylindre intérieur de façon que lorsque le cylindre intérieur est poussé dans le boîtier extérieur, le premier élément de cale appuie sur le second élément de cale, ce qui amène le premier élément de cale à s'étendre radialement, d'où une force de friction accrue entre le premier élément de cale et le cylindre intérieur. Un second ressort (207) soumet le premier élément de cale à une précharge contre le second élément de cale. Un tendeur de courroie peut utiliser cet amortisseur pour soumettre une courroie à une précharge et amortir les oscillations de cette courroie.
