Patent CA-2181438-A1 (CA)
Title: Maximizing process production rates using permanent constraints
Inventor: LIM KIAN YAP
IPC: G05B13/04
Filed: 1995-04-11
Abstract: The present invention optimizes the relationship of variables associated with a process having inputs and outputs such that the process has controlled variables, manipulated variables, associated variables and disturbance variables, to maximize production rates. The method of optimizing the relationship includes the steps of prioritizing errors associated with the controlled variables, optimizing controlled variable deviations from their setpoints over a predetermined future time horizon based upon manipulated variable differential moves, suppressing errors associated with the future controlled variable while penalizing moves having large manipulated variable movement for balancing the reduction of future control error against large manipulated variable movement, weighting the manipulated variables for reducing deviation of the manipulated variable from a predetermined target value set artificially high so as to allow preferential movement with respect to some manipulated variables over other manipulated variables, and applying a constraint deviation variable to effectuate deviations outside allowable bounds.

IPC: G06F9/44
Filed: 1995-12-05
Abstract: A distributed program configuration database system is designed for use on a client-server network. The system consists of a plurality of program servers which maintain version information for various program components. A program developer, upon logging into a client terminal on the network, establishes a workspace or project and connects with one of the servers. After connection to the server has been made, a draft of the program configuration is retrieved from the server. The configuration draft may include information for constructing some of the program components and "bridge" information identifying other program servers where additional program components are located. The workspace uses the component information to assemble components and the bridge information to connect to other servers and retrieve the remaining components in order to assemble the complete source code for a program in the workspace.
Patent CA-2205918-A1 (CA)
Title: Epitaxial growth of silicon carbide and resulting silicon carbide structures
Inventor: IVANTSOV VLADIMIR A
IPC: C30B19/04
Filed: 1995-11-22
Abstract: A method is disclosed for producing epitaxial layers of silicon carbide that are substantially free of micropipe defects. The method comprises growing an epitaxial layer of silicon carbide on a silicon carbide substrate by liquid phase epitaxy from a melt of silicon carbide in silicon and an element that enhances the solubility of silicon carbide in the melt. The atomic percentage of that element predominates over the atomic percentage of silicon in the melt. Micropipe defects propagated by the substrate into the epitaxial layer are closed by continuing to grow the epitaxial layer under the proper conditions until the epitaxial layer has a thickness at which micropipe defects present in the substrate are substantially no longer reproduced in the epitaxial layer, and the number of micropipe defects in the epitaxial layer is substantially reduced.
Patent CA-2207469-A1 (CA)
Title: Variable venturi
Inventor: MATTE SYLVAIN
IPC: B63H11/103
Filed: 1997-06-10
Abstract: The invention relates to a variable venturi for a watercraft vehicle or similarly powered vehicle which allows the operator of the vehicle to selectively choose to operate a watercraft vehicle for achieving maximum acceleration or, alternatively, maximum top end speed. The venturi is comprised of a collar surrounding the venturi adjacent to a distal end of the venturi. At such time as the collar is activated, exposing the water flow exiting the venturi to atmospheric pressure, the diameter of the water flow exiting the venturi is reduced by approximately 1.0 mm. to 1.5 mm. in radius. This slight change in the surface area of the water flow provides a lower mass flow of the exiting water with an increased velocity of the water and top speed of the vehicle. Alternatively, a larger diameter venturi provides a higher mass flow with a decreased velocity and maximum acceleration. In a preferred embodiment, the vehicle comprises a means for allowing the rotation of the engine or the pressure of the water flow to activate an actuator means for altering the surface area of the water exiting the venturi. The preferred embodiment is comparable to automatic shifting of a transmissions for a conventional land vehicle. In an alternative embodiment, the collar may be manually controlled by an operator of the vehicle to modify the surface area of the water flow exiting the venturi, thereby allowing the vehicle to achieve maximum acceleration.

Patent CA-2210814-A1 (CA)
Inventor: BUCHMANN CHRISTA
IPC: B23K26/044
Filed: 1997-07-28
Abstract: To follow and inspect a common edge (13) between two sheet metal blanks (6,7) which are to be welded together, a line pattern (5) is projected across the edge (13) by a projector (2) and is imaged by a camera (3).  The image captured is analysed in order to derive from the trace of the lines information on the gap between the blanks, or on the track of the edge.  The pattern projected has several lines with different light intensities.  When the photographed image is processed, it is then possible even if there is variation in the reflection characteristics of the sheet metal blanks   to select a line which is neither too faint nor too bright in the image obtained and which can therefore be used for meaningful analysis.
