Patent CA-2368220-C (CA)
Inventor: JOHNSON MATTHEW Q
IPC: B23K35/38
Filed: 2000-04-06
Granted: 2004-09-21
Abstract: Deep penetration gas tungsten arc welds are achieved using weld penetration containing one or more compounds selected from the group of compounds consisting of a) a titanium oxide, b) nickel oxide, c) a metal silicide, and d) mixtures of these compounds. A flux containing at least two titanium oxides, nickel oxide, and a manganese silicide is particularly useful for welding a wide variety of materials including nickel-based alloys and carbon and stainless steels. As shown in the graph, a flux containing 23.1 wt. % Ti O, 23.1 wt. % TiO2, 23.1 wt. % Ti2O3, 23.1 wt. % NiO and 7.5 Mn15Si26 achieves at least a 200 percent increase in penetration (filed circles) over a weld without flux (open circles) when used with Alloy 718. The flux can be applie d as a paste, as part of a cored wire or rod, coated on the exterior of a fill er wire or rod. Alternatively it can be mixed with a polymer binder and applied to the weld zone as a hot melt, paint, tape, adhesive, rod, wire or a stick.

Title: Radiation filter, spectrometer and imager using a micro-mirror array
Inventor: FATELEY WILLIAM G
IPC: G01J3/02
Filed: 2000-02-14
Granted: 2006-09-12
Abstract: A spectrometer (10) includes a two-dimensional array of modulatable microm-irrors (18), a detector (20), and an analyzer (22). The micro-mirrors are positioned for receiving individual radiation components forming a part of a radiation source. The micro-minors are modulated at different modulation rates in order to reflect individual radiation components at known and different modulation rates. The micro-mirrors combine a number of the reflected individual radiation components and reflect them to the detector. The detector receives the combined radiation components and creates an output signal. The analyzer is coupled to the detector to receive the output signal and to analyze at least some of the individual radiation components making up the combined reflection. By using a micro-mirror array that modulates the radiation components at different rates, all of the radiations components can be focused onto a single detector to maximize the signal-to-noise ratio of the detector.

Title: A system and method of communicating operating capabilities in a telecommunication network
Inventor: GRAF LESLIE GARY
IPC: H04L29/06
Filed: 2000-07-21
Granted: 2016-09-20
Abstract: The present invention relates to a system and method of communicating operating capabilities in a telecommunication network or networks. The present invention stems from the realisation that mobile telecommunication network resources can be utilised with greater efficiency by maintaining mobile station attributes or operating capabilities at a network node associated with the mobile station. Preferably, the network node is a Visitor Location Register (VLR). Additionally, the network node may be a Home Location Register (HLR), a Mobile Switching Centre (MSC) or a Gateway Mobile Switching Centre (GMSC). In particular, the invention may provide the creation of a list of operating capabilities at a network node upstream from the mobile station.  Having done this, a comparison of this list with another list received from a remote telecommunication element to negotiate operating capabilities at a call set up is achieved without involving communication resources between the mobile station and the network node.

Granted: 2012-03-20
Abstract: Method and apparatus for making a tread-belt assembly for a pneumatic tire using a supply ramp to supply green rubber tread stock for application on a substantially cylindrical green rubber belt package. The green tread stock is advanced along the supply ramp toward the belt package. A final portion of the supply ramp is positioned along a plane tangent to an outer circumference of the belt package. The tread stock is applied to the outer circumference by moving a leading cut end of the tread stock from the supply ramp to the belt package.

Title: Ancrage tissulaire sans noeud
Inventor: MARTINEK JONATHAN
IPC: A61B17/00
Filed: 2001-09-14
Granted: 2009-11-24
Abstract: L'invention concerne un ancrage tissulaire à extension radiale, sans noeud, comprenant un élément externe extensible définissant un passage et un élément interne installé de manière coulissante à l'intérieur du passage. Le mouvement relatif de l'élément interne par rapport à l'élément extensible dans la direction longitudinale provoque l'extension radiale sur l'extérieur d'une partie de l'élément extensible. Cet ancrage tissulaire comprend en outre une section d'un matériau de suture comprenant une première extrémité fixée sur l'extrémité distale de l'élément interne et une seconde extrémité fixée de préférence sur une aiguille de suture. Un passage transversal est formé à proximité de l'extrémité distale de l'élément interne. L'invention concerne également un procédé permettant d'ancrer sans former de noeuds une section de tissu sur une section d'os perforée d'un orifice. Ce procédé consiste à faire passer le matériau de suture à travers le tissu et à placer l'élément extensible et une section de tissu à l'intérieur de l'orifice formé dans l'os. L'extension de l'élément extensible bloque la suture entre l'élément extensible et l'os et permet ainsi de fixer le tissu maintenu par la suture sur l'os. L'invention concerne en outre un procédé permettant de fixer sans l'aide de noeuds une section de ligament dans un orifice allongé foré dans l'os. Ce procédé consiste à faire passer une section de matériau de suture à travers le ligament et à tirer le ligament de manière à l'amener à proximité immédiate de l'extrémité distale de l'élément interne puis à enrouler ou à attacher le ligament sur l'élément interne du côté distal. Un mouvement distal de l'élément extensible par rapport à l'élément interne provoque l'extension de l élément extensible et permet de fixer ainsi à la fois la suture et la section de ligament entre l'élément extensible et l'os. Un mouvement distal de l'élément extensible sépare en outre les sections de suture attachées de l'élément interne.
