Patent CA-2052729-A1 (CA)
Inventor: CHEN ZUI-NIEN
IPC: B25B27/02
Filed: 1991-10-03
Abstract: A gear puller has a body that houses an hydraulic mechanism formed by a pair of piston-and-cylinder assemblies, one assembly being positioned toward a head end of the body, and the other assembly being positioned toward a base end of the body.  An annular oil chamber extends around the head end of the body.  A first check valve sits in a passage between the oil chamber and the cylinder of the one assembly, and a second check valve sits in a passage between the cylinder of the one assembly and the cylinder of the other assembly.  A lever and a rod connected to the piston of the one assembly actuate that assembly.  A series of pawls, connected to the puller body, and a rod connected to the piston of the other assembly define an arrangement for pulling a gear off of a pole. A spring housed in the body biases the piston of the other assembly away from the base end of the body.  A rotatable bolt extends across a flow passage between the cylinder of the other assembly and the oil chamber, controlling oil flow between the two.  Use of the gear puller involves positioning the pawls around the gear and bringing the rod of the other assembly against the pole.  Actu-ation of the lever relative to the head end of the body moves oil from the cylinder of the one assembly to the cylinder of the other assembly, and results in the gear moving relative to the pole.  The bolt is then loosened, allowing the oil in the cylinder of the other assembly to be pushed by the spring into the oil chamber.  The bolt is then tightened before further use of the gear puller.

Patent CA-2092241-A1 (CA)
Inventor: HUSSELTON MAHLON E
IPC: E05F1/04
Filed: 1993-03-23
Abstract: A torsion spring counterbalance assembly having one end of a torsion spring attached to a center support bracket with the other end attached to a torsion shaft around which the torsion spring is pre-loaded with the torsion shaft releasably locked to the center support bracket for allowing the tension of the pre-loaded torsion spring to be released after installation with an overhead garage door to counterbalance the garage door between open and closed positions via lift bands wound about drums mounted at the ends of the torsion shaft and secured to the door bottom by wire brackets.          The drums are selectively connected for rotation with the torsion shaft and disconnected from rotation with the torsion shaft to permit adjustment of the tension and resulting torque of the torsion spring.  A safety interlock mechanism limits the rotation of the torsion shaft relative to the center support bracket in the event of a malfunction upon initial installation.   A manually actuated eccentric cam selectively locks and unlocks the lift band drums for lateral adjustment of the drums on the torsion shaft to properly align the spacing of the drums relative to variations in door width.   A sleeve inside the torsion spring maintains the length of the torsion spring at its fully wound position to prevent lateral thrust on torsion shaft end supports enabling a single spring to be used on garage doors of various sizes and weights.

Title: Restitution des signaux d'horloge dans les reseaux a mode de transfert asynchrone (mta) transmettant des signaux videos a debit binaire variable
Inventor: HASKELL BARIN G
IPC: H04N21/643
Filed: 1993-05-31
Abstract: On surmonte les difficultés de resynchroniser le signal reçu par un récepteur fonctionnant en mode de transfert asynchrone (ATM) grâce à un premier élément à boucle de synchronisation de phase comprenant un comparateur de phase, un filtre, un oscillateur à régulation de tension (VCO) et un compteur de sortie pour resynchroniser le système aux signaux de référence d'horloge (SCR) reçus en mode asynchrone d'un transmetteur ATM lointain. La valeur SCR représente la valeur instantanée de l'horloge de synchronisation d'un système (STC) au moment où s'est effectuée la transmission du signal SCR asynchrone. Au niveau du récepteur, le compteur de sortie est d'abord ajusté à la valeur du signal SCR reçu initialement, de sorte que l'horloge STC peut servir à décoder les cellules de données des paquets de données initialement reçus. Ensuite, on a recours à des indices temporels de décodage et de présentation (PTS/DTS), qui sont présents dans les signaux vidéo et audio, conjointement à l'horloge du système (STC), pour afficher correctement les données reçues. Dans une réalisation de l'invention, on peut réduire les problèmes de valeurs extrêmement faibles de données en mémoire en imposant une valeur de délai (D j), ce qui permet d'accumuler plus de données en mémoire avant de procéder au décodage. L'ajustement de la valeur de délai du canal se fait de façon dynamique,  en évaluant le degré de saturation des mémoires de données et en ajustant la valeur de délai en conséquence. La stabilité de la synchronisation du décodeur vidéo se trouve améliorée si on emploie un second élément à boucle de synchronisation de phase dans le contrôle de l'affichage vidéo, en plus du signal d'erreur de synchronisation. Le second élément à boucle de synchronisation de phase comprend un commutateur, un filtre, un élément de contrôle d'amplitude et un oscillateur à régulation de tension (VCO). Le commutateur change d'état sous l'effet d'impulsions provenant de l'oscillateur VCO et fournit ainsi un signal  instantané d'erreur aux contacts d'entrée du filtre pour chaque unité de présentation vidéo. L'oscillateur VCO possède une fréquence centrale extrêmement stable, dont la variation est contrôlée en limitant l'amplitude de la tension de contrôle à un domaine restreint de valeurs de tension. Les impulsions de sortie de l'oscillateur VCO permettent le décodage des unités de présentation. Une synchronisation plus rapide est obtenue au démarrage en permettant un plus grand domaine d'amplitudes de l'oscillateur VCO, par régulation de l'élément de contrôle de l'amplitude.

Title: Apparatus for Operating a School Bus Safety Device
Inventor: REAVELL JAMES
IPC: B60Q1/50
Filed: 1993-08-17
Abstract: A stop sign and/or crossing arm deployment system is secured to a side and/or the front, respectively of a school bus for deploying a safety stop sign and/or crossing arm between a retracted normal state and a deployed safety state.      A dual power circuit is provided for providing maximum power at the instance of deployment and at the instance of final retraction. Otherwise, a lower power is used to operate a bi-directional DC motor which receives power for the entire time period between deploying and retracting the system. The system provides the lower power level while simultaneously heating the circuitry including the motor for use in cold climates. A single ground switch is used for coupling the motor directly to ground both during the deployed state and retracted state to provide maximum power in momentary cycle times to the motor. A voltage, in the reverse retraction direction of the motor, is applied to the system at all times to immediately commence the retraction portion of the cycle during deployment should the system be deployed and that decision is followed by a decision to cancel such deployment.
