Patent CA-2313514-A1 (CA)
Title: Fall restrict device
Inventor: MCQUARRIE RAYMOND H
IPC: A62B35/00
Filed: 2000-07-06
Abstract: A fall restrict device for use by a lineworker on a wood electric utility pole includes a flexible strap that can be formed into a loop around the pole. A free end of the strap loop is fastened to a body harness worn by the worker. A pair of pole piercing assembly are secured to the strap, each assembly including a planar plastic paddle formed with slots through which the strap is interleaved. The paddles are positioned so as to locate on diametrically opposite sides of the pole when the loop is formed around the pole, and each paddle carries piercing elements oriented to penetrate the pole as the loop is tightened. Tension on the free strap end automatically causes the piercing elements to penetrate the pole. To permit the device to be released from the pole, each paddle defines a fulcrum to one side of its piercing elements that bears against the pole, and a lever to an opposite side of the piercing elements.      The paddles can be manually rotated by means of their levers to pry their piercing elements from the pole.

Patent CA-2316381-A1 (CA)
Inventor: SAMMES NIGEL MARK
IPC: H01M8/06
Filed: 1998-10-01
Abstract: L'invention se rapporte à un appareil conçu pour produire de l'énergie électrique et comportant une pluralité de piles (2) tubulaires à combustible oxyde solide contenues dans une chambre de réaction (40). Ces piles (2) à combustible sont immobilisées à une de leurs extrémités dans un bloc collecteur (51) et leur autre extrémité passe librement par les ouvertures (63) d'un déflecteur (47) de manière à se loger dans une chambre de combustion. Des gaz de réaction sont amenés à l'intérieur des piles (2) à combustible tubulaires à partir d'une chambre de répartition (42) située sous le bloc collecteur (51) et vers la chambre de réaction (41) entourant l'extérieur des piles à combustible par un chemin d'admission annulaire pouvant comporter un catalyseur de reformage. Le chemin d'admission des gaz dans la chambre de répartition (42) et le chemin d'admission annulaire entourant la chambre de combustion sont tous deux en relation de conduction thermique avec la chambre de réaction et la chambre de combustion amène, suivant le cas, les gaz à la température de formation ou à la température de réaction.
Patent CA-2317737-A1 (CA)
Title: Multiple dome single-panel explosion vent
Inventor: LEONARD BRENT W
IPC: B65D90/36
Filed: 1998-12-28
Abstract: An explosion vent (10) for covering an opening (12) in an enclosure (14) subject to the built-up of pressure is disclosed. The explosion vent includes a peripheral flange (16) configured for attachment to the enclosure around the opening, a pressure relief panel (18) positioned within and hingedly connected to the flange, and a plurality of connectors or rupture tab assemblies (19) connecting the unhinged portion of the pressure relief panel to the flange. The connectors break when the enclosure is subjected to pressure build-up for permitting the panel to shift outwardly from the enclosure for uncovering the opening in the enclosure. Rivets (72) are provided for attaching the rupture tab assemblies (19) to the pressure relief panel (18) which function to provide additional panel support and minimize localized bending of the rupture tabs (21) forming a part of assemblies (19) when the explosion vent is subjected to vacuum conditions, but do not interfere with rupture of the tabs and opening of the panel at a relatively low burst pressure. The pressure relief panel has a plurality of domed sections (46-52) presenting at least one valley defining bridge (54-58) therebetween. The domed sections and bridges cooperate to stiffen the panel so that it more uniformly distributes force on the connectors, causing all of the connectors to break at approximately the same time so that the panel more consistently opens at a selected burst pressure level.

Inventor: BECHTEL JON H
IPC: F21V1/00
Filed: 1999-08-26
Abstract: Continuously variable headlamps offer greater flexibility for roadway illumination but offer challenges in automatic control design. Each continuously variable headlamp has an effective illumination range varied by changing at least one parameter from a set including horizontal direction aimed, vertical direction aimed, and intensity emitted. A system for automatically controlling continuously variable headlamps on a controlled vehicle includes an imaging system capable of determining lateral and elevational locations of headlamps from oncoming vehicles and tail lamps from leading vehicles. The system also includes a control unit that can acquire an image from in front of the controlled vehicle. The image covers a glare area including points at which drivers of oncoming and leading vehicles would perceive the headlamps to cause excessive glare. The image is processed to determine if at least one oncoming or leading is within the glare area. If at least one vehicle is within the glare area, the headlamp illumination range is reduced. Otherwise, the headlamp illumination range is set to full illumination range.
