Abstract: Thermal oil recovery operations, such as SAGD, result in waste heat that is typically released to the environment. Bitumen mining operations require heat input for heating fluids used in the mining process. A method and system of recovering heat from a thermal recovery operation for use in bitumen mining operation is described. A heated donor fluid from a thermal recovery operation is used to heat an acceptor fluid for use in bitumen mining via proximal heat exchange using a power cycle or heat exchange module, such as an ammonia and water based Kalina® Cycle. By utilizing waste heat from thermal recovery operations to heat fluids used in bitumen mining, thermal efficiencies are realized.

Abstract: A method of recovering coordinate system information for a geographic data file for which coordinate system information is unavailable. The method includes obtaining a raster image corresponding to the geographic data file, and correlating the raster image to the earth's surface. A list of probable coordinate systems for the raster image is generated, and a statistical analysis is performed for each likely coordinate system candidate. The suggested coordinate systems are then ranked using statistical analysis.

Abstract: Bitumen within raw oilsands may be cracked and fully recovered by light hydrocarbon extraction following exposure to modified natural zeolite catalysts under cracking conditions. The recovered bitumen is reduced in viscosity, with lower boiling point distributions. Effective cracking of oilsands bitumen using economical, abundant and readily disposable natural zeolites represents a significant step towards a waterless and environment friendly extraction process.

Abstract: A process for production of sweet heavy crude oil is disclosed. The process comprises the steps of: removing contaminants from heavy oil, bitumen or bitumen froth to form a substantially dewatered deasphalted oil; and subsequent desulfurization of the substantially dewatered deasphalted oil using sodium metal desulfurization to produce a sweet heavy crude oil. The step of removing contaminants is conducted using extraction with a paraffinic solvent.

Abstract: A method of forming a semiconductor device having two different strains therein is provided. The method includes forming a strain in a first region with a first straining film, and forming a second strain in a second region with a second straining film. Either of the first or second strains may be either tensile or compressive. Additionally the strains may be formed at right angles to one another and may be additionally formed in the same region. In particular a vertical tensile strain may be formed in a base and collector region of an NPN bipolar transistor and a horizontal compressive strain may be formed in the extrinsic base region of the NPN bipolar transistor. A PNP bipolar transistor may be formed with a compression strain in the base and collector region in the vertical direction and a tensile strain in the extrinsic base region in the horizontal direction.

Abstract: An apparatus and related methods using photographic imaging and the interactions between light beams and dairy milk to provide in-line monitoring, analysis, and display of the quality of milk collected from dairy animals. The apparatus is robust in that it is reliable, simple to install, relatively small in size, cost effective, easily cleaned, and low maintenance. The apparatus can be installed directly in-line with the milk collection apparatus for each animal so as to measure the entire milk yield produced by that animal at flow rates typically used in milking parlours without requiring any unusual tube fittings or non-standard equipment. The apparatus is capable of handling analysis of a flow having mixed densities, air/liquid ratios, temperature variations, or any other similar variation of physical characteristics.

Abstract: The present invention provides a method of forming a self-aligned heterobipolar transistor (HBT) device in a BiCMOS technology. The method includes forming a raised extrinsic base structure by using an epitaxial growth process in which the growth rate between single crystal silicon and polycrystalline silicon is different and by using a low temperature oxidation process such as a high-pressure oxidation (HIPOX) process to form a self-aligned emitter/extrinsic base HBT structure.

The method can further include reconfiguring the stored hyperlinks to point to the cached hypermedia content. The presenting step can include displaying Web content in a Web browser. In that case, the Web content can contain hyperlinks to additional Web content. The presenting step also can include playing back multimedia content in a multimedia content player. Finally, the presenting step can include displaying audiovisual television content combined with hypermedia content in a television set.

Abstract: In a swather formed by a tractor and attached heeder for cutting standing crop to form a swath, reel speed and optionally draper speed are controlled relative to ground speed by a control system including a manually operable input and display available to the operator. The control system acts to calibrate” the control output so that the control module has a secondary reference point as to how the PWM valve should function in the event of a speed sensor failure. Instead of using the speed sensor signal as a reference, the control system now compares the set point with the stored table (which may in one example provide 256 values) containing the PWM voltage/current values. These values correspond to a set of actual speed sensor values taken during the profiling procedure, plus extrapolated values equalling 256 points.

Abstract: A system for collecting, treating and disposing of waste fluid includes a station that features transfer, flushing and mixing pumps as well as a bowl that holds the waste fluid. The waste fluid is collected in a container mounted on a cart. The cart container connects to the station so that the waste fluid is transferred from the cart to the station bowl by the transfer pump. The flushing pump has an inlet that communicates with a source of water and a disinfectant dispenser. The flushing pump is used to flush both the cart container and the station bowl, the latter of which communicates with a drain system. The flushing pump also delivers disinfectant to the waste fluid in the station bowl. The inlet and outlet of the mixing pump communicate with the bowl so that it mixes the bowl contents. Buffer is provided to the circulating waste fluid until the pH level drops to a predetermined level.

Abstract: A system for collecting and disposing of liquid medical waste includes a fluid collection cart and a draining and cleaning station. The fluid collection cart includes a pair of containers, each of which includes a draining port and a cap. Each cap includes an outer portion having a flushing port and a bore formed therein and an inner portion having vacuum and patient ports formed therein. The inner cap portion is disposable and removably positioned within the bore of the outer cap portion. Liquid level detectors also communicate with each container. The cart also includes a regulator so a low vacuum level may be pulled on one of the containers while a full vacuum level is pulled on the other container. Fluids are collected in the containers via suction tubes connected to the patient ports. The flushing and drain ports of the containers are connected to corresponding flushing and drain connectors on the station when the containers are full so that they may be drained and flushed.

Abstract: A tractor has hydraulically driven wheels at a cab end and castor wheels at an engine end. It can be driven cab forward in a working mode with a header on the forward end. It is rotated to engine forward in the transport position for more stable higher speed travel. The driven wheels are driven by hydraulic motors each having their own drive pump the output of which is controlled by a cam plate. The speed control is effected by a manually operable lever through a servo-cylinder which locates a speed control arm moving both cam plates to the set position. In a maximum speed position both cam plates are engaged against a stop. The steering is effected by moving the cam plates differentially to drive the wheels at different speeds. The piston rod of the servo-cylinder includes a spring relief so that the speed control arm can back off from the maximum position by moving the servo-cylinder body when steering in the maximum speed position.
