Title: Compact expanding gate valve
Inventor: PARTRIDGE CHARLES C
IPC: F16K3/18
Filed: 2000-10-12
Abstract: A compact expanding gate valve having a valve body defining a flowway and having spaced internal seat rings. Guide elements project internally from the valve body. A valve stem driven gate and segment assembly is movable within the valve body between open and closed positions relative to the seat rings and has control arms mounted by actuating pins to each side of gate and segment members of the gate and segment assembly. The control arms are movable linearly with the gate and segment assembly and are disposed in guided relation with the guide elements during opening and closing movement. During initial movement of the gate and segment assembly from the closed position, the pinned connection of the control arms to the gate member and the segment member causes the control arms to pivot responsive to relative linear movement of the gate and segment members and apply collapsing force to the gate and segment members to collapse the gate and segment assembly to minimize frictional contact thereof with the seat rings and permit its movement by the valve stem from the closed position to the open position.

Patent CA-2331170-A1 (CA)
Inventor: O'PHELAN MICHAEL J
IPC: H01G9/055
Filed: 1999-05-05
Abstract: A wound multi-anodic electrolytic capacitor has a multi-anode stack of strips of high foil gain tunnel-etched aluminum. Inner end edges of the anodes (215A, 215B) in a multi-anode stack are offset from each other by a predetermined distance. Offsetting the end edges of the anodes advantageously reduces mechanical stresses in the capacitor windings. This increases the reliability of the capacitor and advantageously allows a smaller diameter mandrel opening, increasing the energy density per unit volume of the capacitor and allowing its volume to be reduced. When used in an implantable defibrillator or other cardiac rhythm management device, the smaller capacitor advantageously reduces its volume or, alternatively, allows the use of a larger battery, thereby prolonging its useable life.

Abstract: Un téléphone portatif comprend une batterie interne (10) et un bloc-batterie externe (12) qui peut être fixé de manière détachable sur le téléphone. Une unité (72) de contrôle intégrée dans le téléphone contrôle la connexion des batteries respectives à l'entrée (40) de puissance du téléphone, au moyen de la détection de la tension du bloc-batterie. Chaque fois qu'un bloc-batterie externe présente une tension supérieure à une valeur minimale prédéterminée, le bloc-batterie externe est connecté (51) à l'entrée de puissance du téléphone pour fournir la puissance permettant au téléphone de fonctionner, ceci permettant d'allonger la durée de vie de la batterie interne. Lorsque la tension du bloc-batterie externe chute en-deça de la valeur minimale, ou que le bloc-batterie est enlevé, l'unité se place automatiquement sur la puissance (50) de la batterie interne pour que le bloc-batterie puisse être changé sans que le téléphone subisse une interruption de son alimentation en puissance, si le téléphone est sous tension ou pendant un appel. Un procédé et un appareil améliorés de charge de batterie à plusieurs phases pilotée par logiciel sont utilisés pour charger les blocs-batteries interne et externe. Le procédé (200) de charge de batterie préféré utilise une technique de charge à plusieurs phases comprenant une phase (206) de charge à régime lent, une phase (208) de charge rapide et une phase (214) de charge d'appoint. La batterie interne est chargée à sa capacité presque maximale par régime lent (en fonction des besoins) puis par charge rapide. Le bloc-batterie externe est lui aussi et de la même manière chargé à sa capacité presque maximale. Ainsi les deux batteries sont chargées à leur capacité presque maximale pendant une durée de charge sensiblement réduite par rapport au temps nécessaire pour effectuer la charge totale.

Patent CA-2339911-A1 (CA)
Inventor: DON-CAROLIS CEDRIC
IPC: H04B10/516
Filed: 2001-03-07
Abstract: This disclosure applies to an improvement on conventional optical transmitter architecture which allows the production of bursts of data signals with accurate selectable optical frequency within the target optical band. The invention overcomes the limitation caused when the monitor and feedback circuits do not provide sufficient control within the required time. A key aspect of this invention is the ability to ensure the output frequency is well controlled, even for rapid changes in output frequency, as in packet on wavelength systems. Two approaches are discussed: one for cases when the laser cannot be tuned within an allowed switching time, and one which applies when the laser can be tuned sufficiently quickly but requires on-going stabilization. The second approach may be used to improve the performance of the first approach.  The first approach, in which a single laser cannot tune accurately within the required time, makes use of multiple lasers implemented with an appropriately fast optical switch to select the desired laser, each laser being tuned and locked on the frequency required for the packet it will address while an other is (or others are) transmitting. In the second approach, in which a single laser can be tuned to the nominal frequency during the transition time, the implementation improves the initial spectral quality and frequency accuracy on switching to a new frequency through: -setting the initial frequency as determined by a set of parameters in a table, -improving the output quality during the data transmission, -updating the table parameters based on the changes necessary to improve the signal. The second approach is particularly appropriate for rapid cyclical requirements for a particular wavelength, as the conditions for any wavelength may be nominally unchanged from cycle to cycle.  If the tunable lasers cover only a fraction of the desired optical band, multiple lasers may be operated in paralleled to provide full coverage of the wavelength band, and combined with a fast optical switch, while being controlled with either of the two control approaches. This disclosure also applies to the use of such rapidly tuned optical sources to provide data units, frames or packets where each data unit can be of arbitrary frequency within a set of operational frequencies.

Filed: 1999-08-12
Abstract: A single row or single plant harvesting machine (10, 410, 510) which is particularly useful for harvesting test and developmental plots used by plan t breeders of cereal grains. The harvester has a cutting head (23, 223, 323, 423, 523) with cutter (35, 236, 336) that severs the stalks of the grain plants (30) and produces cuttings (41). The cuttings are threshed by an impeller (51, 351, 551) to free the grain, seeds (60) or other plant product . The impeller is also used to generate a vacuum which draws the cuttings (41)  into an intake port (40) which feed the thresher (51, 351, 551). The impelle r further conveys the threshed cuttings to a separator (70, 470, 570) which separates the grain seeds (60) from the straw and chaff which are discharged  onto the ground. The harvester can be carried on a human operator (20) or be  rolled using a wheeled carriage (480). The harvester eliminates bundling and  remote threshing while also speeding and simplifying the harvesting of small  test and developmental plots.

Abstract: The simulation system is used in the course of firing exercises, in particular with a laser beam, for simulating conditions which would arise if actual ammunition were used. For identifying a response device (2), a transmitting device (1) transmits a coded radiation, which is detected in the responder device and is converted into electrical signals, which are supplied to a central unit (25) on the receiving end for transmitting identification messages back to the transmitting device in accordance with decisions made by this central unit (25). The transmitting device generates laser radiation or electromagnetic pulses or pulse bursts containing information which is coded in such a way that the response pulses being sent back by the responder device to the transmitting device additionally enable a central unit (15) on the transmitting end to calculate the distance between the transmitting device and the responder device.
