Patent CA-2050339-C (CA)
Title: Insulated wire for high temperature use
Inventor: INAZAWA SHINJI
IPC: H01B13/06
Filed: 1990-12-26
Granted: 1997-12-02
Abstract: Disclosed is an insulated wire which comprises a conductor, a first insulating metal oxide layer which is formed around the conductor, and a second insulating metal oxide layer, containing ceramics particles mixed by addition, which is formed around the first insulating metal oxide layer. The aforementioned insulating metal oxide layers can be formed by changing a precursor of a metal oxide to a ceramics state, using a method such as a sol-gel method or a thermal decomposition method. Further, the mixed ceramics particles are more preferably in the form of a fine plate. This insulated wire is excellent in flexibility, emits no gas, can maintain insulation even under a high temperature, and has a high breakdown voltage.
Patent CA-2058212-C (CA)
Title: Machining apparatus
Inventor: BACKHOUSE ANTHONY EDWARD
IPC: B23Q15/22
Filed: 1991-12-20
Granted: 2004-06-22
Abstract: Machining apparatus comprises a boom displaceable along spaced rails and a carriage displaceable along the boom perpendicularly to the displacement direction of the boom. A machining station is adjustably supported on the carriage by three adjustment means to adjust a machine head, such as a milling cutter, towards and away from a workpiece disposed between the rails beneath the machining station. Adjustment of the machine head results from inaccuracies in the level of the rails and/or the displacement of the carriage. Variations in the level of the rails and/or carriage are determined by a respective sensor associated with each adjustment means which monitors a reference defined by a planar laser beam. Alternatively one of the three adjustment means between the machining station and the carriage may be replaced by a pivot with the third adjustment means being arranged to adjust the machine head relative to the remainder of the machining station. In an alternative embodiment, the boom is rotatable about a pivot support within a cylindrical workpiece with the machining station mounted on the remote end of the boom and optionally displaceable with a carriage along the boom. The boom is supported at its remote end on the workpiece by wheel units.

Title: Control culvert attachment
Inventor: NOONAN JOHN P
IPC: E03F7/06
Filed: 1993-02-04
Granted: 1995-01-03
Abstract: The highway and railroad culverts, with or without modification, have been susceptible of being blocked by the natural instincts of beavers, causing flooding and conditions hazardous to human life. In this invention, the culvert opening Is modified by an up-stream excavation of a reservoir and the attachment of a beaver-proof device to the existing culvert. This device consists of a vertical inlet extending Into a dug-out reservoir to a depth sufficient to conceal the bottom flow of the water from beavers. The device also conceals the culvert opening where beavers usually start their dams. The water flow is not restricted as the device allows water to flow through the existing culvert at its maximum capacity. The device is adaptable to round or square culverts and can beinsulated to control winter ice build-up. A steam pipe is installed in the unit for the use of steam in spring to thaw ice if necessary.            The unit is adaptable for different size culverts.

Title: Epoxy/polyolefin coating process
Inventor: COX JAMES J W
IPC: C08J7/04
Filed: 1991-08-16
Granted: 1999-03-30
Abstract: A method of coating metallic pipe is disclosed. The method comprises heating the pipe to a temperature of at least 200 .degree.C and applying an epoxy resin composition having a thickness of at least 300 microns to the outer surface of the heated pipe. Before the epoxy resin composition has completely cured, but preferably after it has gelled, a coating of a modified polyolefin is applied in a thickness of up to 500 microns. The modified polyolefin is a homopolymer or copolymer of hydrocarbon alpha-olefins having 2-10 carbon atoms that has been modified by grafting with ethylenically unsaturated organic carboxylic acid or anhydride. An outer coating of a polyole fin is then applied in a thickness of at least 300 microns, the polyolefin being a homopolymer or copolymer of hydrocarbo n alpha-olefins having 2-10 carbon atoms and preferably a homopolymer of ethylene or propylene, or a copolymer of ethylene an d a C3-C10 hydrocarbon alpha-olefin. The resultant coating is resistant to impact damage and cathodic disbondment. The c oated pipe may be used in buried pipelines in the petroleum industry.

Patent CA-2124812-C (CA)
Inventor: BROWN RICHARD I
IPC: B04B5/00
Filed: 1993-03-23
Granted: 2004-06-01
Abstract: A system (234) for monitoring the interface region between cellular constituents and plasma in a blood separation chamber (80) employs a sensor mechanism (236) for emitting upon the interface region energy that is absorbed by the cellular constituents. The sensor mechanism (244) also detects the intensity of the energy that is not absorbed by the interface region to generate an unabsorbed intensity output signal. The system (234) moves the interface region relative to the sensor mechanism during a prescribed time period. A first circuit (268) measures variations in the unabsorbed intensity output signal over the prescribed time period and generates a time based output. A second circuit (270) can derive the physical size of the interface region based upon the time based output.

Title: Method and apparatus for improving motion compensation in digital video coding
Inventor: HORNE CASPAR
IPC: H03M7/36
Filed: 1994-08-24
Granted: 1999-06-22
Abstract: A novel method and apparatus for use in digital video compression provides improved block-based motion compensation using the global motion of a video frame.  A video frame comprising a plurality of blocks may be compressed for transmission using block motion vectors. Motion vectors are generated by block matching a block to be coded with a block within a reference frame and determining the displacement therebetween.  To effect block matching, motion compensation techniques define a search window within one or more reference frames within which a displaced block will be found.  According to the present invention, the location of the search window within a reference frame is defined using the global motion of the frame.

Abstract: A media player and the clock which controls it are integrated into a single object This integration may be achieved by the construct of inheritance between objects in an object oriented programming environment.  A software class for player objects is established which inherits from a software class for clock objects. In this way, a player "is a"  clock. This integration provides improved synchronization among different media, and simplifies design of applications which employ player objects and clock objects. Each object is synchronized to a RootClock object which operates at the speed of the fastest media player in the system. The RootClock may be separated into "low" order and "high" order components and a compare register in order to induce interrupt overhead.
