Patent CA-2389318-A1 (CA)
Inventor: CUNNEEN DAN
IPC: G08B13/24
Filed: 2000-11-06
Abstract: A self-contained conveyor member including a plurality of EAS deactivators is adapted to connect in-line to an existing conveyor system for transporting goods at a manufacturer or distributor's site. The conveyor member has attached to it several commercially available EAS marker deactivators spaced apart to provide continuous coverage across the width of the conveyor and such that the deactivation field of each of the deactivators do not cause interference of the deactivation fields of the adjacent deactivators. EAS markers attached to articles being transported on the conveyor member will pass through at least one of the deactivation fields and will be deactivated. The deactivators selectively deactivate a variety of specific EAS markers such as RF and/or magnetomechanical EAS markers.

Abstract: The invention provides a strategy to start a parallel HEV powertrain engine while maintaining a smooth vehicle response to driver demand using the motor while simultaneousl y closing an engine disconnect clutch. In the preferred embodiment, the strategy starts an engin e (based on, for example, driver demand), closes the disconnect clutch commands a desired motor/generator speed, fuels the engine, calculates a desired engine torque and gradually reduces actual motor/generator torque while proportionally increasing actual engine torque until motor/generator torque is zero while maintaining vehicle velocity using, for example, a proportional plus integral controller . The prediction of a desired motor/generator speed can be: a trajectory comparison based on present and past vehicle velocity and acceleration or on vehicle accelerator position, or a determination of whether the vehicle is in speed control mode. The system can also add additional strategies such as a termination strategy if a vehicle brake is applied.

Title: Method of web turn-up in a web winder and apparatus therefor
Inventor: CASPAR ROMAN C
IPC: B65H19/26
Filed: 2002-07-25
Abstract: A method and apparatus for cutting and transferring a web onto a new empty reel core utilizing at least one water jet cutter located immediately upstream and adjacent to a nip formed between a driving drum and the empty reel core and that further utilizes twin water jet nozzle tail cutters located further upstream of the first water jet cutter.      The twin cutters cut a strip into the web from the interior of the web which strip is directed downstream past the first water jet cutter. The first water jet cutter is limited to cut across the strip to completely sever the strip and form a leading tip that is wrapped around the new empty core. Thereafter, the water jet tail cutters move to the outside edges of the web widening the strip to the complete width of the web which is then wound onto the new empty core.

Abstract: L'invention concerne un capteur servant à détecter des propriétés chimiques d'un liquide, par exemple dans un puits de pétrole, qui comprend une électrode (22a) de mesure du pH en verre et une électrode de référence (22c). L'électrode (22a) en verre est constituée d'une électrode (30) de détection étroite située à la surface d'un substrat (20) électriquement isolant, d'une couche de verre (36) recouvrant l'électrode (30) de détection et de deux électrodes (32, 33) de nettoyage ; une électrode de nettoyage s'étend le long de chaque côté de l'électrode de détection sur toute la longueur de détection de celle-ci. Les électrodes (32, 33) de nettoyage ne sont pas recouvertes par la couche de verre, et sont séparées l'une de l'autre de 3 mm au maximum. L'application d'une tension entre celles-ci produit des bulles de gaz par électrolyse qui détachent tout encrassement de l'électrode (22a) en verre. L'électrode (30) de détection peut présenter une forme de zigzag, les électrodes (32, 33) de nettoyage étant intercalées entre des parties successives du zigzag.

Abstract: A method and system state-of-the-art private VoIP network (206) for delivery of high quality, lower cost voice and data services to business customers across the United States is shown. The unique implementation of the latest networking and Internet technologies over a privately managed network (206) produces Quality of Service (QoS) that rivals traditional circuit-switched calls (102, 104) and allows customers to capitalize on the convergence of traditional circuit-switched voice networks (202, 204) with packet-based networks (224). Proprietary account management, call detail recording, and accounting software complements the equipment and satisfies the administrative needs of business customers. Customers receive the added security and flexibility of "virtual private networks" through the implementation of IP  technology, advanced switching equipment, and Asynchronous Transfer Mode ("ATM") operation of the fiber optic backbone (224).

Abstract: A clamping cartridge is provided which comprises a plurality of clamping mechanisms spaced apart on a frame or chassis. The clamping mechanisms are generally oriented perpendicular to their direction of spacing. The clamping mechanisms are of the type which comprise a pair of relatively movable jaws which are biased together. The jaws are openable by levers which are connectable to or integral with the jaws such that when the end of the levers are moved relatively toward one another, the jaws are caused to open. The actuation fevers extend through the frame where they engage a camming mechanism which is operable to urge together respective pairs of levers of each clamping mechanism so as to cause the plurality of clamping mechanisms to open in unison and to permit the respective pairs of levers of each clamping mechanism to separate so as to cause the jaws of the plurality of clamping mechanisms to close or clamp against one or more objects which may have been placed therebetween. The clamping cartridges are useful in a variety of applications requiring clamping of one or more articles in a side-by-side relationship. One such application is a transportation/storage rack which includes a plurality of aligned horizontal and vertical clamping cartridges for clamping the edges of glass panels.
