Patent CA-2293200-C (CA)
Inventor: KILLEN DALE H
IPC: A01D57/20
Filed: 1999-12-24
Granted: 2003-04-15
Abstract: A hydraulic system for a detachable implement such as draper platform for  a combine utilizes a platform-mounted pump supplied with return oil from the existing reel drive motor. The system utilizes the existing combine hydraulic connection for the reel drive to supply oil to the draper belt drive motors. Oil from the combine powers the reel drive motor and then flows into a manifold block (mixing chamber) before entering the inlet of the draper belt drive pump. This pump is sized to provide sufficient oil flow to power the draper belt drive motors, arranged in serie s. Return oil from the belt drive motors is routed back to the manifold block where it can  mix with incoming oil from the reel drive pump before returning to the combine reservoir or being recirculated to the belt drive motors. The hydraulic system avoids the  need to equip the platform with a complete hydraulic system and avoids the need to modify the existing hydraulic system of the combine.

Title: Moteur piezoelectrique
Inventor: CUNNINGHAM JOHN
IPC: H01L41/09
Filed: 1998-07-07
Granted: 2009-01-13
Abstract: L'invention concerne un moteur piezoélectrique comprenant un corps de moteur, une couche compliante en communication avec le corps de moteur, et un nombre prédéterminé de pattes en communication avec la couche compliante, laquelle met les pattes en contact avec un substrat. Chacune des pattes comporte une plaquette piezoélectrique, fonctionnant de préférence en mode de cisaillement. L'actionnement d'une plaquette piezoélectrique entraîne le déplacement de la patte correspondante par rapport à un substrat. Ce déplacement transfère l'énergie de contrainte à la couche compliante. L'énergie stockée dans la couche compliante peut être libérée, faisant ainsi avancer le moteur le long du substrat. Les pattes peuvent être capables de se déplacer indépendamment les unes des autres, sequentiellement ou par groupes ou unités prédéterminés. Les pattes peuvent également être disposées en paires, les paires de pattes étant capables d'actionnemnt simultané. Le moteur est capable de garder une force de maintien élevée en l'absence de puissance absorbée.

Abstract: The invention is a scent-free wildlife blind. .The blind comprises a room-like shelter having a door, a plurality of windows, a small vent near ground level, and a flexible tube extending from the top of the shelter to a height of approximately 30 feet from the ground. When the wind hits the shelter, the windspeed will be higher at the top of the tube than at the bottom vent. The pressure exerted by the wind on the air inside the shelter is inversely proportional. to the wind speed. Therefore, the pressure difference will force air in through the bottom vent and out through the top of the tube, carrying the scent of the occupants out of the blind high enough so that. nearby animals will not smell the occupants.

Title: Multiple job signals per processing unit in a multiprocessing system
Inventor: HOLMBERG PER ANDERS
IPC: G06F9/50
Filed: 1999-11-12
Granted: 2011-05-10
Abstract: The invention is directed towards a multiprocessing system (10) having multiple processing units (34A-D). According to the invention, for at least one of the processing units in the multiprocessing system, a first job signal is assigned to the processing unit for speculative execution of a corresponding first job, and a further job signal is assigned to the processing unit for speculative execution of a corresponding further job. The speculative execution of said further job is initiated when the processing unit has completed execution of the first job. If desirable, even more job signals may be assigned to the processing unit for speculative execution. In this way, multiple job signals are assigned to the processing units (34A-D) of the processing system, and the processing units are allowed to execute a plurality of jobs speculatively while waiting for commit priority. By assigning multiple job signals for speculative execution by one or more processing units, the effects of variations in execution time between jobs are neutralized, and the overall performance of the processing system is substantially improved.
