Patent CA-2347340-A1 (CA)
Inventor: THIEVIN MARVIN
IPC: E01H4/00
Filed: 2001-05-11
Abstract: A method for forming an ice or winter road on muskeg during freezing conditions is effected by driving over the muskeg a vehicle supported on at least two rollers each of a width sufficient to span the vehicle and each having sufficient buoyancy to support the vehicle when floated in water such that the vehicle is carried on the muskeg by the rollers and such that the vehicle will float if it breaks through the muskeg. The vehicle is steered by articulation of front and rear sections of the frame and carries a drive motor and cab. The rollers have provided on the peripheral surface a plurality of generally conical projection members at angularly and axially spaced positions thereon and extending outwardly therefrom for engaging into the surface of the muskeg. The projection members engage through any snow cover on the muskeg into the muskeg so as provide an air channel for transmission of cold from the air into the muskeg for freezing water in the muskeg to form a layer of ice sufficient to provide a base for the winter road.

Title: Self-contained mapping and positioning system utilizing point cloud data
Inventor: HINTON ERIC HERBERT
IPC: G06T17/05
Filed: 2001-05-14
Abstract: A self-contained mapping and positioning system for underground mining is provided that is capable of mapping the topography of a region, such as a mine tunnel, and further being able to use the mapped data to determine the position of an object, such as a mining vehicle, within the mine tunnel. The system includes an inertial navigation system, a central processing unit, a three-dimensional database, a three-dimensional camera system, an operator console and a survey system having a three-dimensional laser scanner. The survey system using the three-dimensional laser scanner produces point cloud data, i.e., a set of data points representing the topography of the region. The point cloud data is stored within a storage device until the entire region is mapped and then transmitted to the operator console to be post processed.  After post processing, the data is exported to the three-dimensional database and the indexed for ease of use by the central processing unit. To determine the position of the object within the region, the system of the instant invention initializes the object in its current position.   The object is then either remotely or directly guided to another position from the current position where it is brought to an estimated position by the inertial navigation system or is remotely controlled for performing work, e.g., drilling a mine heading.  After a predetermined time of moving the object, there is an error in the position of the object and the operator console makes a call to the central processing unit on board the object to automatically calculate the true position based on the point cloud data stored within the database to update the position of the object. This is done by approximating a search range for the database according to t:he estimated position. A subset of data corresponding to the search range is removed from the database. The three-dimensional camera system then scans images of the surface in proximity to the object and converts the images to a patch of point cloud data. The patch of point cloud data is then matched against the subset of data corresponding to the search range of point cloud data removed from the three-dimensional database until there is less than a predetermined minimum error distance. At that point, the true position of the object is known. This new position is then put back into the inertial navigation system and the positional data of the object is updated with the correct positional data.

Title: Flush valve assembly with flex tube
Inventor: PARSONS NATAN E
IPC: F16K31/40
Filed: 2001-12-10
Abstract: A toilet room flush valve includes a body having an inlet and an outlet. There is a valve seat between the inlet and outlet and a valve assembly is movable within the body and positioned to close upon the seat to control flow from the inlet to the outlet. A cover is mounted upon the body and defines a pressure chamber with the valve assembly. There is a bypass connecting the inlet and pressure chamber whereby the pressure therein maintains the valve assembly upon the seat. A flex tube is fixed relative to the cover at one end thereof, with the other end of the flex tube being attached to the valve assembly remote from the pressure chamber. There is a passage in the flex tube opening to the body outlet at one end thereof. A vent passage connects the pressure chamber with the flex tube passage and a pilot controls flow through the vent passage. Movement of the valve assembly toward the cover in response to venting of the pressure chamber causes the flex tube to bend while remaining stationary relative to the cover. A filter is attached to the flex tube and controls the flow of water from the pressure chamber to the vent passage.

Patent CA-2365935-A1 (CA)
Inventor: GAN HONG
IPC: H01M4/08
Filed: 2001-12-17
Abstract: The present comprises an electrode having the configuration: first active material/current collector screen/second active material. When one of the active materials is in a powder form, it is possible for that material to move through openings in the current collector screen to "contaminate" the interface between the other active material and the current collector. The present invention consists of having the other electrode active materials in a form incapable of moving through the current collector to the other side thereof. Then, the assembly is pressed from the direction of the other electrode active material. This seals off the current collector as the pressing force moves the current collector against the powdered electrode active material.

Filed: 2000-04-26
Abstract: A hydrodynamic seal for location in a seal groove of a structure, such as a housing and for dynamic sealing engagement with a relative rotatable surface.  Elevated contact pressure zones caused by pressure manipulation features (18) located at least partially on the dynamic sealing surface (8) of the seal provide for controlled lubricant movement within the dynamic sealing interface between the seal (2) and the relatively rotatable surface for enhanced lubrication of the seal (2) even when the seal (2) defines a wide sealing footprint with the relatively rotatable surface. The pressure manipulation feature (18) may be defined by projections at least partially from the dynamic sealing lip which are compressed against the relatively rotatable surface or depressions which define pressure manipulating edges which react with the lubricant in the dynamic sealing interface responsive to relative rotation.  The projections (18) or depressions may be of elongate form and may be oriented in skewed relation with respect to the direction of relative rotation.

Title: Pivoting hooks for parallelogram lift linkages
Inventor: BUSS STEVEN HENRY
IPC: A01D34/64
Filed: 2002-02-28
Abstract: Pivoting hooks usable with four bar parallelogram implement lift linkages are provided. The hooks are pivotally attached at the forward edge of the implement to receive the cross bar of a suspension mechanism such as that taught in U.S.  Patent 5,025,617. The pivotal connection and axis about which the hooks are supported on the deck comprise one corner of the four bar parallelogram lift linkage. The hooks pivot forwardly and downwardly to receive the cross bar and then swing up as tension is applied to the hanger to support the deck. As the cross bar slides forwardly into the throats of the hooks when the hanger is tensioned, it is retained in the proper parallelogram lift geometry so that the deck remains level as it is adjusted throughout its vertical cutting height. The use of the pivoting hooks permits decks with extended fore and aft dimensions to be used with existing four bar parallelogram designs.
