Patent CA-2389464-A1 (CA)
Title: Assemblage de materiaux a basse temperature
Inventor: HAYDEN JOSEPH S
IPC: G02B6/26
Filed: 2000-11-01
Abstract: L'invention concerne un procédé d'assemblage de matériaux similaires et/ou non à basse température (cristaux, verres et revêtements métalliques) par appariement à basse température avec une solution aqueuse inorganique contenant du phosphore. Dans un mode de réalisation préféré, les matériaux à assembler sont polis, nettoyés et assemblés à la solution contenant du phosphate entre les surfaces polies. Une mise sous vide peut être exécutée afin d'assister la fabrication du joint. Le composite est éventuellement traité thermiquement aux fins d'accroissement de la résistance, de la durabilité chimique et des performances optiques. La liaison ainsi formée présente une faible biréfringence. Elle est forte et pour ainsi dire invisible sur le plan photonique. Les joints permettent de fabriquer des dispositifs photoniques hybrides au moyen d'un procédé d'assemblage inorganique à basse température.

Title: System and method for surveying utility outages
Inventor: ALLPORT DOUGLAS
IPC: H02J13/00
Filed: 2002-09-06
Abstract: Utility failures are automatically detected and potential causes for these failures are automatically located and identified without having to physically search a utility provider's network. Detection systems capable of monitoring utility status are located at each, or a subset, of the customer premises serviced by a utility provider. A monitoring system, capable of correlating the geographical location of the detection systems with the geographical location of the equipment that comprises the utility provider's network, is located at a utility provider and interconnects with the detection systems through a communications network. The monitoring system queries the detection systems to determine utility status and to subsequently locate an outage and deduce a possible cause for the outage.  Detection systems can also be configured to automatically contact the monitoring system to report utility status. The monitoring system is also capable of sending customer based information messages to the detection systems.

Title: Closure with gas-barrier liner and package incorporating same
Inventor: DRUITT RODNEY M
IPC: B65D41/04
Filed: 2002-09-13
Abstract: A package made up of a container (30) with a closure assembly (10) applied thereto. The closure assembly has o molded plastic closure element (12) with a top panel (14) end an annular skirt (16) that depends downwardly from the top panel and surrounds and engages a finish of the container. The closure assembly (10) also has a barrier disc (20) that underlies the top panel, but is out of engagement with a rim (32) of the container (30) when the closure assembly is applied to the container. The closure element has an integral sealing fin (22) with an inner end (24) as a first portion and an outer end (26) as a second portion, and the second portion, as molded, extends inwardly and downwardly from a distal end of the first portion. When the closure assembly is applied to the container, the second portion of the sealing fin is folded back toward the end portion of the sealing fin and engages the rim and a terminal side portion (34) of the finish of the container to form a top and side seal between the closure assembly (10) and the container (30). The outer end of the sealing rib also traps the sealing disc against the underside of the top panel of the closure but out of engagement with the container. The barrier disk is molded or fabricated from a material, for example, EVOH or LCP, that has excellent resistance to the permeation of O2 or other gases therethrough, and may have an oxygen-scavenging material embedded therein when it is desired to use a closure assembly with such a barrier liner for the packaging of oxygen-sensitive materials, such as beer and other malt beverage products, dairy products and real juices.
Patent CA-2403782-A1 (CA)
Inventor: MILAM WILLIAM THOMAS
IPC: H02J7/00
Filed: 2001-03-21
Abstract: A charge pump power converter efficiently provides electrical power by dynamically controlling a switch matrix of the charge pump. Instead of open- loop oscillator-based control, a dynamic controller provides power upon dema nd by sensing the output voltage and changing the operating frequency of the charge pump in response. Moreover, this closed-loop dynamic control intrinsically voltage regulates the output voltage of the charge pump power converter without the inefficient addition of a step-down voltage regulator,  downstream of the power converter. In addition, this closed-loop dynamic control allows for maintaining a desired output voltage even with variations  in the input voltage. Also, the dynamic control accommodates the advantages of using ultra-capacitors in the charge pump. The power converter is capable of  operating with a sub-one volt input voltage incorporating low-threshold, low  on-resistance power MOSFET switches in the switch matrix of the charge pump.  A progressive start-up circuit further allows the power converter to start fro m a discharged state even with a sub-one volt input voltage.

Patent CA-2406763-A1 (CA)
Inventor: URQUHART EDWARD F
IPC: B65D77/06
Filed: 2002-11-05
Abstract: A container primarily for hot (or cold) beverages such as gourmet coffee has an outer shell formed of a stiff sheet material having heat insulating properties such as cardboard which can be erected from a flat storage condition to enclose an inner lining member for containing the liquid. The inner liner is blow molded from a plastics material to form an integral structure including a neck and a handle projecting through openings in the shell so as to be exposed on an exterior of the container for manual transportation and lifting of the container. The use of a blow molded integral liner allows the handle to be integral with the liner and relatively stiff as a tubular member parallel to an inclined upper surface of the liner.  An optional folded leg can be provided to allow the liner to be drained through an optional spigot on the neck. An optional accessory box can be slung on a flap engaged around the neck. The molded liner is translucent allowing the fill level to be observed through a flap window provided in the side wall of the shell.

Abstract: The swing mower is a mower with a walking-caster-hitch that allows mowing in the ditch adjacent to the road while leaving the tractor to operate up on the road surface. The walking-caster-hitch of the swing mower also allows mowing with the tractor directly ahead of the centerline of the mower. In addition, the walking-caster-hitch can be rotated through the whole range of motion while mowing under full power. The walking-caster-hitch is simple and eliminates the need for any additional costly constant-velocity universal joints and gearboxes. The swing mower may be equipped with a sensor out in front of the mower to sense obstacles such as signposts and then swing the walking-caster-hitch so that the mower clears the obstacle automatically. The walking-caster-hitch typically utilizes a single caster wheel. In addition, two or more swing mowers equipped with the walking-caster-hitches can be pulled behind one tractor.
