Patent CA-2259527-A1 (CA)
Inventor: HERSHMAN LAWRENCE J
IPC: G01M11/00
Filed: 1999-02-09
Abstract: A calibration technique for lasers of a data acquisition module in a signal processing system, wherein an optimal value of a phase modulation coefficient is calculated for each laser and used as the amplitude of a cosine wave signal for the laser module carrier frequency for phase modulation of the laser output signal. The phase modulation coefficient is determined from a global average I/Q ratio, calculated for all channels of the selected laser module, as an average of all I/Q ratios of in-phase and quadrature phase angle components of the signals returned from the sensors. The phase modulation coefficient for the selected laser module is determined empirically or by dividing the previously determined phase modulation coefficient by the previously determined global average I/Q ratio.

Title: Three-dimensional intraluminal ultrasound image reconstruction
Inventor: TENHOFF HARM
IPC: A61B5/00
Filed: 1997-09-15
Abstract: A method for imaging an organ or internal structure within a body to obtain three-dimensional reconstruction of the organ includes steps of providing an intraluminal ultrasound imaging system (23) capable of obtaining echographic images of the surrounding of a catheter imaging tip (22) located inside the body of a patient. The intraluminal ultrasound catheter imaging tip (22) is positioned within a region of interest (97) inside the body of the patient and a plurality of echographic images are obtained during deliberate movement or pull-back of the catheter (21), each image corresponding to an echographic data set. The position of the catheter axis with respect to each echographic data set obtained during pull-back is recorded. The recorded position of the catheter tip (22) can be used to calculate a catheter pull-back trajectory in three-dimensional space. The images are stacked around the catheter pull-back trajectory by positioning the origin of a first image at a first recorded position, and positioning subsequent images at their respective distances from the first image, wherein each echographic data set is positioned so that the catheter axis is aligned with the catheter pull-back trajectory.

Title: Process for casting and forming slag products
Inventor: BERRY RICHARD
IPC: F27D27/00
Filed: 1999-07-20
Abstract: The present invention relates to a process and apparatus to cast and form slag directly from the molten state into crystalline or amorphous products suitable for use as decorative and structural building and construction materials. Molten slag and additives are refined at high temperature in a treatment furnace for a period of hours. The eventual entrapped gas content is controlled using a variety of methods, such as vacuum pressures and bottom stirring with inert gas. The molten slag is cast directly into moulds, and these moulds form the slag into any shape desired. The farmed products are immediately introduced into a heat treatment furnace at temperatures at or above the glass transition temperature (GTT) for the case of crystalline products, or just below the GTT for amorphous products. The product is thermally cycled over a period of hours to relieve thermal stresses during coaling to ambient temperatures. If desired, the product can be coated using enamel or glaze and cured in another furnace, or metal plated.

Title: Network access in multi-service environment
Inventor: SKILLEN RICHARD PRESCOTT
IPC: H04L12/02
Filed: 1998-02-25
Abstract: In current voice telephony, CATV, and wireless networks, traffic is channelized for both access and transport. This channelizationis wasteful of resources where multiple services have varying demands for bandwidth and holding times, or a service generates traffic that is bursty in nature. The invention solves these problems by providing flexible and adaptable multi-service access to the networks. Customer requirements are checked by monitoring traffic on a local access at a connection request and/or during the established connection, and the local access is configured according to the transmission requirements. The local access can also be configured in response to the network information. In furhter realizations, either or both the CPE connector and access module include common bus architecture which forms a backbone LAN for handling a multiplicity of CPEs and/or networks.

Title: Lower pre-heat block for use in metal scarfing apparatus
Inventor: ENGEL STEPHEN A
IPC: B23K7/06
Filed: 1999-09-17
Abstract: A lower pre-heat block assembly 9 for use with a metal scarfing apparatus 5 is disclosed. The lower pre-heat block assembly has a lower block 38 and an extension 39 engaged upon and in overlying relationship with a front face 46 of the lower block. A gas discharge outlet 56 is defined within the front face of the block. The extension may partially overlie the gas discharge outlet such that a gas discharge orifice 70 is defined in the front face of the block by the extension. The extension includes an upper face 58 which extends forwardly from the front face of the block, and is recessed with respect to an upper face 41 of the block. So constructed, when a sheet-like oxidizing gas flow 82 is passed over the upper faces of the block and the extension, respectively, and as a fuel gas 85 is emitted through the gas discharge outlet, the fuel gas is pneumatically compressed between the oxidizing gas flow and the upper face of the extension such that the fuel gas is substantially uniformly distributed along the longitudinal length of the lower pre-heat block assembly and forms a uniform sheet-like fuel gas flow (90) which underlies and adjoins the sheet-like oxidizing gas flow so as to prevent ambient air from aspirating into the oxidizing gas flow and thereby result in a smooth and uniformly scarfed surface on the metal workpiece.

Filed: 1998-05-27
Abstract: La pièce mécanique à surface antiabrasion est caractérisée en ce qu'elle comprend un corps métallique fritté obtenu par métallurgie des poudres et un revêtement en cermet déposé par la technique au laser. Le revêtement a une certaine épaisseur dont une portion est métallurgiquement liée au corps métallique. Le dépôt par laser permet de fondre en surface la pièce frittée à revêtir sous l'effet du faisceau laser. La surface de la pièce frittée à recouvrir est donc fusionnée sur une épaisseur pouvant aller de 10 .mu.m à 1mm, ce qui permet la fermeture des pores en surface, typique aux pièces frittées et, par conséquent, l'accroissement de sa résistance au choc. De plus, la faible surface couverte à un instant donné par le laser permet l'autotrempage de la zone exposée, suite au déplacement du faisceau, par effet de puits de chaleur du volume métallique environnant. Le revêtement obtenu selon la présente invention présente aussi une très faible porosité à cause de la fusion complète des poudres de la pièce frittée par le laser.

Abstract: L'invention concerne : un article en plastique nouveau et utile, en particulier un élément de bardage en plastique, dans lequel est incorporé un motif coloré d'accentuation; un granulé de colorant d'accentuation qui est utile dans la production d'un tel article; et un procédé de production dudit article faisant appel à de tels granulés. Selon ledit procédé, on extrude un produit en plastique à partir d'un matériau de base constitué de particules de poudre et de granulés de colorant d'accentuation façonnés spécialement. Les granulés de colorant d'accentuation sont des masses alliées de résines et de pigment qui sont plus grandes que les particules de poudre du matériau de base et présentent une température de ramollissement Vicat supérieure à celle du matériau de base. Les granulés alliés sont conçus pour fondre de façon contrôlée et se mélanger également de façon contrôlée avec le matériau de base. Pendant le procédé d'extrusion, les granulés de colorant d'accentuation commencent à se ramollir et se dispersent plus tard que le matériau de base, et provoquent une dispersion, pouvant être controlée, du colorant d'accentuation dans le matériau de base, ce qui résulte en la formation de stries de colorant d'accentuation dans le produit obtenu présentant des caractéristiques pouvant être controlées. Le procédé convient particulièrement à la production d'un effet simulé du grain du bois ou de striures dans un élément de bardage en plastique, et, tel qu'il est décrit, ce procédé permet d'obtenir des striures dures, des striures douces et des striures tachetées ou marbrées dans lesquelles plus d'un colorant d'accentuation sont utilisés simultanément. L'invention concerne en outre une nouvelle composition de granulé de colorant d'accentuation, comprenant du poly-.alpha.-méthylstyrene en tant que seule résine à température de ramollissement Vicat élevée.
