Patent CA-2156815-A1 (CA)
Inventor: BONNER BRIAN BERNARD
IPC: B23K1/00
Filed: 1995-08-23
Abstract: The present invention discloses a novel, moisture-free atmosphere for brazing carbon steels that provides good braze flow and brazed joint quality with minimum or no formation of soot on brazed joints. According to the present invention, carbon steels are brazed in continuous furnaces using a moisture-free atmospherecontaining a mixture of three gases including nitrogen, hydrogen, and carbon dioxide. The key features of the invention involve (1) formation of moisture, which is needed to facilitate braze flow and to minimize formation of soot on brazed joints, in-situ in the heating zone of the furnace by the reaction between hydrogen and carbon dioxide and (2) reduction in the overall amount of a reducing gas required for brazing carbon steels by keeping moisture out of the cooling zone. The use of a moisture-free three gas atmosphere has been unexpectedly found to (1) eliminate the heed of an expensive and difficult to control external humidification system, (2) provide flexibility in adjusting moisture content of the atmosphere in the heating zone of the furnace simply by adjusting the flow rate of hydrogen or carbon dioxide or both, and (3) facilitate rapid conditioning of the furnace by keeping moisture out of the cooling zone. The moisture-free atmosphere has also been unexpectedly found to provide good braze flow, fillet formation, and brazed joint quality while minimizing or eliminating formation of soot on brazed joints.

Title: Method and apparatus for configuring systems
Inventor: LYNCH JOHN
IPC: G06F17/50
Filed: 1994-03-21
Abstract: The present invention employs a generative approach for configuring systems (10) such that a system may be configured based on component or resource requests (60), or input in the form of need. The present invention provides a constraint-based configuration system using a structural model (12) hierarchy. The structural aspects of the model provide the ability to define a model element as being contained in, or by, another model element. In addition, the structural model (12) provides the ability to identify logical datatype and physical interconnections (30) between elements and establish connections between elements. To configure a system, the present invention accepts input in the form of requests (e.g., component or resource) or needs, such as an expression of a need for a desktop computer system to be used in a CAD environment.

Abstract: A veneer hoisting apparatus in which at the hoisting of a veneer by a piercing body, the decrease in sustaining force applied to the veneer by the piercing body is prevented, and it rarely happens that the veneer drops down from the piercing body.  With the construction of the piercing body 7 and a sustaining member 9, when the veneer is hoisted through the piercing body 7, although the central portion side of the veneer 5 in the direction of its fiber is hung down about the root of the piercing body 7 which pierces the veneer as a fulcrum, and the end side thereof is curved upward, no fulcrum occurs at a position apart from the root of the piercing body in the direction of the fiber of the veneer.

Abstract: Méthode permettant de déterminer à quel moment transmettre une communication d'une ressource de communication à une autre ressource dans le cas d'un système de communication entre sites multiples (100). La méthode comporte les étapes suivantes : lorsqu'une unité de communication (113) est assignée à une ressource de communication, elle commence à surveiller l'exploitabilité du signal de la ressource de communication assignée et d'un ensemble prédéterminé de ressources de communication de remplacement. Une unité de diffusion (107) associée à la ressource de communication assignée surveille aussi l'exploitabilité du signal de cette dernière. Lorsque la disponibilité du signal des ressources de communication assignées est jugée insuffisante par l'unité de communication ou l'unité de diffusion, l'une des ressources de communication de remplacement est sélectionnée en fonction de l'exploitabilité déterminée du signal de cette dernière, de sorte que l'unité de communication puisse continuer la communication.

Abstract: An exhaust port timing control apparatus for a two-cycle engine includes a control valve which is moved upward and downward in the linear direction across an exhaust port by moving the control valve slidably and rotatably around a supporting axis. The control valve is operated by rotating a pivot provided at an end portion of the control valve. Since the control valve moves linearly, the clearance between the control valve and the exhaust port can be kept very small, whereby the leakage of gas out of the cylinder can be minimized and consequently an accurate exhaust port timing control and a stable engine operation are achieved.

Title: Ultrasonic bone testing apparatus with repeatable positioning and repeatable coupling
Inventor: BARRY DONALD
IPC: A61B8/13
Filed: 1996-05-14
Abstract: An ultrasonic bone testing apparatus  has  a  foot well assembly and a shin guide assembly which are mechanically coupled to secure a foot and lower leg of patient in a comfortable position,  during the measurement process.   The  shin guide assembly includes a molded form lined with contoured foam lining which has a shin restraint section, an instep guide section and a foot restraint section.  An adjustable strap attached to the shin restraint section is placed around the calf.   An instep support guide having sliding blocks is mounted on the molded form.  The sliding blocks are inserted into respective channels of respective bridge brackets of the foot well assembly to attach the shin guide assembly to the foot well assembly.  The channels and sliding blocks are lined with respective ratchet teeth to permit the latching of the shin guide assembly to foot well assembly at a selected one of multiple levels, and thereby the foot and lower leg can be secured comfortably.  The apparatus further includes a transducer drive mechanism for positioning a pair  of transducer assemblies.   A controller automatically modifies the positioning of the transducer assemblies until ultrasonic coupling  is achieved and a receiving transducer receives a signal of a predetermined quality.   The distance between the transducers is continuously measured by a position encoder.  The controller calculates a speed of the ultrasonic signals  through  the  foot  using  the  distance  between  the transducers which is determined by the position encoder.  The controller uses temperature readings from a temperature sensor to improve the accuracy of the position encoder measurements and correct for temperature dependent inaccuracy in the ultrasound measurement.  A coupling pad and acoustical delay line of the transducer assembly provide a waveguide function to collimate an acoustical beam a sufficient distance along a propagation axis to allow wavefronts to evolve onto a more uniform intensity pattern.  The elastomer coupling pad has an angled surface which expels air bubbles from a contact area when pressure is applied to the pad.  The coupling pad preferably is made of polyurethane with a durometer of 10 to 15 Shore A.  Petroleum jelly is used as a coupling gel to more efficiently couple the ultrasonic energy.   The coupling gel may be replaced by  self-wetting coupling pads.
