Patent CA-2350365-A1 (CA)
Inventor: PLANTAN RONALD S
IPC: B60T17/08
Filed: 2001-06-13
Abstract: A vehicle brake actuator including an improved piston assembly having a piston plate including an upstanding annular rim portion and a piston rod including a shank portion having a generally cylindrical head portion and an annular rim portion on a free end of the piston rod head portion which is deformed radially into a cylindrical internal surface of the piston plate upstanding rim portion, permanently attaching the piston plate and rod. The method includes piercing and extruding the upstanding rim portion of the piston plate and forming radially projecting teeth on an external surface of the head portion of the piston rod, driving the head portion of the piston rod into the upstanding rim portion of the piston plate, preventing relative rotation of the piston rod and head. The improved piston assembly of this invention eliminates welding, permitting finishing of the piston rod and plate prior to assembly and reduces cost.

Patent CA-2353683-A1 (CA)
Inventor: LEJEUNE PHILIPPE
IPC: G01R31/01
Filed: 2001-07-23
Abstract: A method for the testing of electronic components, proposing an optimization of a duration for the tests of this method, consists in choosing an earliest possible measurement date (Dm) with respect to an initial testing date (Do).    According to this method, this earliest possible measurement date is chosen by considering statistical images (IS) obtained on a population of components (P1, P2) and by comparing these statistical images with one another by means of a criterion. This criterion takes account of a mean and an amplitude of the responses given by the test population during iterations of a same test with different measurement dates.

Patent CA-2369693-A1 (CA)
Inventor: EDLAND DAVID W
IPC: F16B13/06
Filed: 2002-01-30
Abstract: The rivet includes a screw element which rotates within a body element. The body element includes an upper collar, integral with the body head, which is longitudinally stabilized with respect to the rotating screw element. The body element further includes a lower collar which is internally threaded and engages the external threads of the shank of the screw element. The lower collar therefore traverses a portion of the shank of the screw element as the screw element rotates.  Folding legs join the upper collar and the lower collar. In the uninstalled position, the folding legs are parallel to and abut the screw shank. However, in the installed position, the lower collar approaches the upper collar and the legs fold so as to be substantially perpendicular to the screw shank.

Title: Automated container loader for refuse vehicle
Inventor: HUANG SIMON
IPC: B65F3/02
Filed: 2002-02-08
Abstract: An automated container loader for mounting to the side of a vehicle adapted for collecting the contents of curbside residential waste containers. The vehicle has a vehicle body longitudinally attached to the vehicle chassis. The automated container loader is attached to the vehicle chassis by means of a slide and positioned adjacent the side of the vehicle body. The container loader is equipped with a lift arm having a gripping element comprising a gripper housing having an opposing pair of gripping jaws. The gripping jaws are pivotally attached to the gripper housing on opposite sides to their respective arms, thereby creating a cross-pivoting arrangement. The distance between the free ends of the gripping jaws is thereby reduced when in the open position. The cross-pivoting arrangement further allows the container loader to have a thin overall width, accomplished through use of a non-folding single-section gripping jaw.

Title: Looper and cutter drive mechanism for sewing machine
Inventor: SAKUMA KOUICHI
IPC: D05B37/04
Filed: 2001-03-05
Abstract: In a looper and cutter drive mechanism for sewing machine, an upper looper and a lower looper are respectively disposed below a throat plate, respective loop-taker points of these loopers are arranged in the same direction such that the loop-taker points pass a front side of the needle as seen in the stitching direction. The upper looper and the lower looper are driven such that the upper looper and the lower looper perform movements having traces on planes substantially parallel to each other. Due to such a constitution, the looper drive mechanism has both of the lockstitching function and the over-edge stitching function and can perform both functions by a single sewing machine. Further, the rotational movement of an upper shaft of the sewing machine is transferred to the upward and downward movement by way of a motion transfer mechanism which is operated in an interlocking manner with the rotational movement and a fabric edge is cut by an upper cutter which is operated corresponding to the upward and downward movement and a lower cutter which is cooperatively operated with the upper cutter. Here, the upper cutter is slidably guided by a cutter drive portion which is pivotally mounted on a frame . The motion transfer mechanism is connected to the upper cutter by way of a clutch. The clutch transfers power to the upper cutter at the time of performing the cutters of the cutter drive portion and pivotally moves the cutter drive portion to a shunting position and interrupts the transmission of power to the upper cutter at the time of not performing the cutters.

Abstract: L'invention porte sur un système de télécommunications sans fil comportant plusieurs stations radio de base desservant chacune une partie du système. A chaque station de base est associée une antémémoire qui enregistre les fichiers régulièrement demandés par des unités distantes de l'aire de couverture de la station de base correspondante. Quand une station de base reçoit d'une unité distante un message, elle l'analyse pour savoir s'il contient une demande de fichier. Si c'est le cas, la station de base recherche si le fichier est disponible dans l'antémémoire. Si oui, la station de base répond à la demande et envoie le fichier demandé. Si non, la station de base envoie le message à un contrôleur central qui par le biais d'Internet retrouve le fichier dans le serveur détenant le contenu approprié et le transmet à la station de base.
