Patent CA-2286012-A1 (CA)
Title: Parallel service-rate controllers in atm switches
Inventor: NICHOLS STACY W
IPC: H04L12/56
Filed: 1998-04-06
Abstract: Techniques of service-rate controls in ATM switches are described, and apparatus for their implementation are devised. The techniques fall in two categories: frequency domain controls, and time-domain controls. The regulators control the service rate on a per-class basis or on a per-connection basis. Some class regulators operate at very high speeds of the order of several gigabits per second and cover a medium number of classes, 32 for example. Other regulators operate at high speeds of the order of several-hundred megabits per second, and cover a very large number of classes, e.g., 10,000. A compound regulator which combines both types of regulators is also described. The compound regulators extend the range of controllable classes considerably, covering some 200,000 classes. The main advantages of the regulators of the invention are simplicity, robustness, and high performance.

Patent CA-2301450-A1 (CA)
Title: Water treatment system and method
Inventor: SWALES GRAHAM EDWARD
IPC: C02F1/78
Filed: 2000-03-21
Abstract: A method of handling grey water and optionally at least a portion of the black water for disposal from vehicles such as boats, recreational vehicles or rural dwellings such as cottages, camps and the like, not having direct access to sewer systems, involves the treatment of such waste water with ozone. A batch system is used whereby a predetermined quantity of water to be treated is captured in a treatment tank. A circulating pump withdraws water from the tank and pushes the water along a treatment conduit, the conduit containing an ozone/water mixer and returns the water to the treatment tank. The treatment conduit has a discharge valve that is maintained in a closed position for a selected period of time. Ozone is fed to the ozone/water mixer from an ozone generator which is advantageously fitted with an air pump to pressurize the feed gas. After the selected treatment time, the batch is discharged to waste through the discharge valve. Advantageously, the ozone generator can also be used to "polish" raw water from a lake or stream to enhance its usability on board a vessel or in a rural dwelling.

IPC: B60G17/019
Filed: 1998-11-13
Abstract: A dampener for a shock absorber of a vehicle, such as bicycle, is mounted within a telescoping front fork including a stanchion tube (616) and a coaxial slide tube (618). The dampener includes an internally received hydraulic fluid sleeve (640) that defines a hydraulic chamber in which a piston assembly (656) is disposed. Movement of the piston assembly (670) through hydraulic fluid within the hydraulic chamber is selectively adjusted by metering the flow of bypass hydraulic fluid to the back side of the piston assembly by adjusting a fluid bypass assembly disposed longitudinally within the stanchion tube. The responsive valve assembly includes outlet and inlet ports, and biased bypass valves that move between open and closed positions in response to sensed velocity and/or displacement of the piston assembly, thereby adjusting the damping of the shock absorber.

Abstract: L'invention concerne un système de clapet à fermeture automatique à monter dans l'orifice de distribution d'un récipient, dans un capuchon de fermeture ou similaires. Ce système comprend un premier élément de fermeture (7) présentant une partie de paroi (11) cintrée en matériau élastique, contenant une ouverture de passage (14), qui peut être déformée de manière élastique sous l'effet d'une première force de pression différentielle composée de forces agissant sur des surfaces opposées, pour passer d'une position de fermeture à une position de distribution. Ce système comprend en outre un second élément de fermeture (8) présentant une partie de paroi (12) cintrée, pour étanchéifier l'ouverture de passage, lorsque le premier élément de fermeture est en position fermée. Afin de compenser la pression dans un récipient muni du système de clapet, lorsque le récipient ne subit plus l'influence d'une force de compression augmentant la pression, le second élément de fermeture (8) peut être libéré de la relation d'étanchéité par rapport à l'ouverture de passage (14) du premier élément de fermeture (7), sous l'effet d'une seconde force de pression différentielle dirigée à l'encontre de la première force de pression différentielle et composée de forces agissant sur les surfaces opposées.
Patent CA-2312386-A1 (CA)
Inventor: PILSITS JOHN P
IPC: C10M173/02
Filed: 1998-11-04
Abstract: A method of use of a composition including either or both isomers of hydrogenated methylbenzotriazole, namely, 5-Methyl-1H-Benzotriazole or 4-Methyl-1H-Benzotriazole which have been at least about 50 % hydrogenated, to form corrosion inhibiting films on metal surfaces in an aqueous environment.  The hydrogenated methylbenzotriazole compositions provide both improved passivation and improved film persistence when charged to aqueous industrial systems either on a continuous or on an intermittent basis. Continuous dosing is generally kept at a constant 0.5, typically 1-2 ppm in the aqueous system to be treated; intermittent doses are generally 10-20 ppm once every week or two or more. Beyond the improved characteristics described above, films formed from the inventive composition also reduce spiking in corrosion rates immediately following halogen addition; foster faster return to pre-halogenation corrosion rates post-halogenation; and reduce the rate of conversion of phosphonate to orthophosphate, which reduces scale potential.  For these reasons, the present compositions are either continuously or intermittently fed and effective to inhibit corrosion or copper and copper alloy surfaces subjected to alkaline, neutral or slightly acidic aqueous systems.

Abstract: An accommodating intraocular lens (32) to be implanted within the natural capsular bag (20) of a human eye from which the natural lens matrix has been removed through an anterior capsule opening in the bag circumferentially surrounded by an anterior capsular remnant (22). During a postoperative healing period following surgery, the anterior capsular remnant fuses to the posterior capsule of the bag by fibrosis (30) about haptics (36) on the implanted lens while the ciliary muscle is maintained in its relaxed state by a cycloplegic to prevent dislocation of the lens, and the lens is deflected rearwardly by the fibrosing anterior capsular remnant to a distant vision position against the elastic posterior capsule (24) of the bag in which the posterior capsule is stretched rearwardly. After fibrosis is complete, natural brain-induced contraction and relaxation of the ciliary muscle relaxes and stretches the fibrosed anterior remnant and increases and reduces vitreous pressure in the eye to effect vision accommodation by the remnant, the posterior capsule, and vitreous pressure. A method of utilizing the intraocular lens to provide a patient with vision accommodation.
