Patent CA-2044957-A1 (CA)
IPC: B23D45/00
Filed: 1991-06-19
Abstract: A non-destructive saw blade for composite material is disclosed. The saw blade has a series of teeth which are formed with cutting elements which are spaced inwardly from an outer circumferential edge and have sides which extend outwardly from planar sides of the saw blade. The saw blade is designed to cut yieldable material without cutting the carrier medium which can be a conveyor belt or a caul. Cutting is achieved by pushing the blade into the yieldable material until a cutting element engages the material. Movement of the blade then causes the cutting ele-ment to cut the yieldable material until a full depth cut is accomplished. The conveyor belt or caul is not cut by the saw blade outer edge which acts like a smooth disk. The saw blade can include a wear strip positioned on the outer circumferential rim to lengthen the life of the saw blade and conveyor belt or caul.

Patent CA-2055442-A1 (CA)
Title: Enzymes and their use in drug detection
Inventor: BRUCE NEIL CHARLES
IPC: C12N1/20
Filed: 1990-05-11
Abstract: Two enzymes, one an acetylmorphine carboxyesterase (AMCE), the other a morphine dehydrogenase (MDH), have been isolated from bacteria. The AMCE degrades heroin to morphine and the MDH oxidises morphine to morphinone, with the aid of a cofactor. These reactions are used in detection of heroin (using the two reactions coupled together) or morphine. The enzymes can be incorporated in sensors for this purpose.

Title: High performance passivation for semiconductor devices
Inventor: OUELLET LUC
IPC: H01L23/29
Filed: 1991-08-14
Abstract: A method of passivating a semiconductor device, comprises depositing a first dielectric passivation layer on the surface of the device, forming at least one planarization layer over the first passivation layer from an inorganic spin-on glass solution containing phosphorus and silicon organometallic molecules that are pre-reacted to form at least one Si~O~P bond between the phosphorus and silicon organometallic molecules, and subsequently depositing a second dielectric passivation layer on said at least one planarization layer(s). This results in improved step coverage of the underlying topography and permits much better protection against moisture related degradation than standard vapour phase deposited passivation layers even when the thickness of such layers is increased.

Title: Electron emitting structure and manufacturing method
Inventor: FEIST WOLFGANG M
IPC: H01J29/62
Filed: 1992-02-07
Abstract: Abstract of the Disclosure A field emitter includes an electron emitting structure spaced from an anode structure, with the intervening gap being substantially evacuated.  The electron emitting structure includes a first electrically conductive layer spaced by an insulating layer from a second conductive layer, and a generally circular aperture disposed through the layers.  The anode structure includes an electrically conductive layer.  Electrostatic forces, provided from a potential applied between the first conductive layer and the anode structure, causes an electron beam to be drawn from a cathode provided by a peripheral edge portion of the first conductive layer within the aperture onto an adjacent surface portion of the anode structure.  Such field emission occurs under the control of a potential applied between the first and second conductive layers of the electron emitting structure with the second conductive layer functioning as a control electrode of the emitting structure.  The anode structure converts the electrical energy from the electron bombardment into visible light energy.  In one embodiment, potential applied to a third conductive layer of the emitting structure serves to focus the electron stream on the anode structure.  Methods of manufacturing the disclosed electron emitting structures are also described.

Patent CA-2072774-A1 (CA)
Inventor: VON EHR JAMES R II
IPC: G06F3/033
Filed: 1992-06-30
Abstract: There is disclosed a video graphics system and method for creating variable width lines such that the lines may be easily edited.  As a line image is created, a center point of that image along its length is temporarily established having width information at various points.  This width information is used to create an outline of image of the desired shape, the outline having point data spaced at intervals.  This point data can then be edited by a user to create different shapes.  In situations where a pressure sensitive stylus is used to create the variable length line, a look-back technique is employed to insure that the line remains wide at the end point even though the user is reducing pressure as the system is removed from the pad.

Abstract: ABSTRACT    A coolant system is disclosed for use with a machine tool in which coolant is used to both cool and lubricate a workpiece and cutting tool.  The system of the present invention utilizes a positive displacement pump with one or more spray nozzles each having a restricted orifice whereby the coolant is sprayed from the nozzles at a relatively high velocity and pressure enabling the coolant to be precisely directed to the cutting location to provide optimum cooling and lubricating of the workpiece and cutting tool.  Check valves are provided for both the pump inlet and outlet lines to maintain the pump in a primed condition and prevent drainage of coolant from the coolant system when the pump is not operating.  The system filter is mounted to a flexible coolant line to enable the filter to be raised from the coolant reservoir and the filter is coupled to the coolant line by a quick connect/disconnect coupler to enable the filter to be raised from the reservoir and quickly replaced with a clean filter when  the  first  filter becomes  clogged  and  requires cleaning.

Title: Dynamic payload monitor
Inventor: KYRTSOS CHRISTOS T
IPC: G01G19/08
Filed: 1991-05-28
Abstract: A dynamic payload monitor (10) measures and displays payload weight for a loader vehicle (11) during tip loading by sensing the hydraulic pressure of the lift and tilt cylinders (14, 15) and the geometry of an implement linkage (12). The payload weight is computed by curve fitting the sensed lift cylinder pressure and geometry data to a second order polynomial, and then performing interpolation or extrapolation with a pair of pressure versus position reference parabolas obtained during calibration. Tilt cylinder curves are derived by curve fitting tilt cylinder pressure and lift cylinder geometry data to a third order polynomial. The tilt cylinder curves are then compared to a plurality of tabulated tilt cylinder curves. Tip loading conditions are detected and the computed payload weight is modified in response to the magnitude of the tilt cylinder pressure. The weight computation algorithms used in the dynamic payload monitor are applicable to a number of work vehicles having at least one work implement linkage and at least two hydraulic cylinders for modifying the linkage geometry.
