Patent CA-2377846-A1 (CA)
Title: Header position control with forward contour prediction
Inventor: COERS BRUCE ALAN
IPC: A01D41/14
Filed: 2002-03-21
Abstract: A system for harvester header height and tilt control includes a sensor, such as a crop edge detector, mounted on the harvester for predicting ground contour of an area a substantial distance in front of the header for generally the entire width of the header. An on-board processor calculates the desired header height and tilt for that area in advance of the harvester reaching the area. The early ground contour measurements enable faster and smoother header height adjustments requiring reduced hydraulic power. The predicted contour also facilitates early compensation for effects of abrupt header attitude changes resulting from harvester ground wheels or tracks riding on that contour. The system can be used to maintain header height a preselected distance below the crop heads to reduce harvester throughput.

Patent CA-2385216-A1 (CA)
Inventor: RAMAKRISHNAN SRIKANTH
IPC: G02B6/32
Filed: 2002-05-06
Abstract: An important consideration in making a fiber optic device (e.g., comprising fiber in a polished tube at a certain angle and GRIN lens) is to limit sense, maintain and/or measure the gap-width between these two polished surfaces before they are either fused or glued for optimum performance. In automating the configuration, the gap is sensed, apart from optimizing in the transverse plane to minimize the loss. In the present application, a limit sensing method and system is provided to improve the effectiveness in automated manufacturing systems, by exploiting the electromechanical properties of induced EMF (Electro-Magnetic Force) by an electrical coil in presence of a magnet at mechanical resonance. Once it is known when two optical surfaces to be glued are said to have zero gap (i.e., contact between the surfaces), the present system provides an annunciation from limit-sensing electronics.  Afterwards, it is easier to back-off (separate the surfaces) up to maintain a gap using a micrometer, manually or by a stepper motor longitudinally.
Patent CA-2387430-A1 (CA)
Inventor: KIELLAND PETER JOHANN
IPC: E05D11/00
Filed: 2002-05-09
Abstract: A support rack for hanging garments that also acts as a door's hinge-pin. A  length of metal rod having the same diameter as the door's hinge pin is bent at two locations to form a triangle having a vertical portion, a horizontal portion and a diagonal portion. The rod's two ends are selectably joined to each other by means of a point on one end inserted into a side-socket formed near the rod's other end. The rod's first and second bends locate the two rod ends such that spring biasing maintains the pointed end seated into the side-socket. To install the garment rack, the vertical rod portion of the open triangle is inserted downwards through one of the door's hinges, thereby replacing its standard hinge-pin. The triangle's pointed, diagonal portion is then forced into the side-socket, thereby closing the triangle at its lower corner. The outer extremity of the triangle is thereby supported at a distance from the hinge axis and swings independent of the door. A vertical member with protruding clothes pegs is hung from the triangle's outer end to serve as a garment rack. Another embodiment adapted for hanging towels utilizes multiple cantilevers that swing about a lengthened, straight hinge-pin.  Another embodiment includes shelf modules to provide horizontal storage space for articles.

Filed: 2001-03-15
Abstract: The present invention relates to a phase detector and utilisation of the phase detector for synchronisation of a digital signal with a clock signal. It is an object of the present invention to provide a phase detector with improved characteristics including fitter tolerance and fitter transfer. It is another object of the invention to provide a phase detector that generates an output signal that, when used as a control signal in a phase or frequency locked loop, keeps the gain of the control loop substantially invariant to the transition density of the phase detector input signals. According to the invention, these aspects are fulfilled by provision of a phase detector for detection of a phase difference between a first signal and a second signal. The phase detector comprises a first logic circuit for detection of a data transition of the first signal and a second logic circuit that generates a logic output signal of a first logic value upon detection of a data transition of the first signal if a transition of the second signal occurs before the transition of the first signal and of a second logic value if the transition of the second signal occurs after the transition of the first signal.

Title: Gasification system
Inventor: MAXWELL ROSS H
IPC: F23G5/04
Filed: 2003-02-07
Abstract: A gasification system for producing useful energy from a source of biomass material includes a gasifier for partially combusting biomass material into gaseous fuel, a contained fuel preparation site for preparing biomass material to be delivered to the gasifier, a boiler for combusting gaseous fuel from the gasifier to produce useful energy, and an air delivery system for directing combustion air to at least one of the gasifier and the boiler from the contained fuel preparation site. This arrangement recovers energy normally lost to atmosphere in the form of exhaust from biomass drying facilities. Drawing combustion air from the contained fuel preparation site also permits the fuel preparation site to be maintained at a negative pressure in relation to atmosphere, therefore any odour that is produced from the preparation of the biomass at the site is contained within the closed air delivery system and used for primary combustion at the gasifier or at the boiler.

Patent CA-2423372-A1 (CA)
Inventor: WENSTRUP DAVID E
IPC: D01F1/06
Filed: 2001-05-17
Abstract: A method of solution dyeing a polymeric material during polymerization to form a base color shade, and subsequently externally dyeing the polymeric material by either yarn dyeing or piece dyeing to produce a final color shade. The base shade that is formed may then be transformed into a desired final shade chosen from a wide variety of final shades. Ultraviolet protection is also provided in the solution dyeing step, by introducing an ultraviolet stabilizing agent into the polymeric melt. By providing a yarn or a substrate having a solution dyed base color that may be transformed into a wide variety of different final color shades, inventory is more likely to be utilized rather than wasted. Less inventory space is required, and the process is much more efficient. Material handling costs are decreased with a lower inventory, fewer stock keeping units of starting material are required, and the threat of obsolescence of the remaining inventory is diminished. Further, lightfast qualities in the final product are enhanced, and the final shade may be applied late in the fabric formation process, thus allowing quick response to customer color orders.
