Patent CA-2346080-A1 (CA)
Inventor: THOMAS PHILIP N
IPC: A62C35/68
Filed: 1999-05-18
Abstract: L'invention concerne un actionneur pour soupape de retenue, destiné plus particulièrement à un système de protection contre l'incendie à sec. La soupape de retenue réagit à une chute de pression d'air dans le système, provoquée par l'ouverture d'une ou de plusieurs têtes d'arrosage dans le système de protection contre l'incendie. Le mouvement de l'actionneur vers sa position ouverte établit une ligne d'évacuation d'eau, tout en ouvrant avantageusement un orifice d'aération, antérieurement fermé hermétiquement, pour l'air sous pression à l'intérieur de l'actionneur. La fermeture hermétique de l'orifice d'aération peut être ajustée manuellement pour compenser les tolérances de fabrication. L'actionneur est en mesure de réagir, soit à l'amplitude de la chute de pression d'air du système, soit à la vitesse de la chute de pression d'air dudit système.

Title: Method of determining the throughflow of a gas mixture
Inventor: KUNTER STEFAN
IPC: G01F1/688
Filed: 2001-06-29
Abstract: In a method of measuring the throughflow of a gas mixture, the gas mixture flows past a flow sensor which includes a heating device and a first temperature probe reacting to the temperature of the heating device. A temperature which is characteristic of the temperature of a liquid above which the gas mixture stands as vapour is measured with a second temperature probe. A first measurement signal characterizing the composition of the gas mixture and thus its heat dissipation capacity is produced by means of the known vapour-pressure curve of the liquid and the temperature of the liquid. A second measurement signal characterizing the throughflow of the gas mixture is produced by means of the heating power supplied to the heating device, the temperature of the first temperature probe and the first measurement signal. The method can be used when monitoring the gas return to a filling system and when controlling the gas pump used therein.

Title: Broadband pulse-reshaping optical fiber
Inventor: EVANS ALAN F
IPC: G02B6/036
Filed: 1999-11-10
Abstract: A pulse-reshaping optical fiber having a core with refractive index nc surrounded by a cladding layer, the diameter of the core changing monotonically along the length of the fiber. The core includes a central region having a maximum refractive index n1 and a moat region disposed radially adjacent to the central region. The moat region has a minimum refractive index n2 which is sufficiently low that the index delta .DELTA.2 of the moat region with respect to nc is not greater than 0.1 %. The moat region affects the change in dispersion with respect to fiber cladding diameter, as well as providing the pulse-reshaping fiber with low dispersion versus wavelength slope. The pulse-reshaping fiber is particularly useful in association with optical transmission systems where high transmission rates and narrow pulse widths are desired, including components such as high pulse rate wavelentgh-division-multiplexers (WDMs) and optical regenerators.

Title: Allumage d'arc pour appareil de soudage a l'arc
Inventor: DYKHNO IGOR
IPC: B23K9/067
Filed: 1999-12-27
Abstract: Dans cette invention, une électrode de soudage (102) et une pièce reliées par une alimentation de soudage (106) sont reliées simultanément à au moins deux alimentations haute tension supplémentaires (110, 112). On transmet une courte impulsion apériodique haute tension de la première alimentation haute tension (110) à l'intervalle situé entre l'électrode et la pièce, de manière à générer une décharge électrique et à créer un passage électro-conducteur dans l'air entre l'électrode (102) et la pièce. On superpose sur cette courte impulsion une autre impulsion haute tension plus longue provenant de la seconde alimentation haute tension (112). On obtient alors une impulsion étendue et la durée de la décharge de courant augmente. On chauffe ensuite le passage électro-conducteur. Sa résistance diminue alors et un arc s'allume. Lorsque la tension du passage électro-conducteur diminue jusqu'à une valeur inférieure à celle du circuit ouvert de l'alimentation de soudage (106), le courant de soudage commence à s'écouler de cette dernière via l'électrode de soudage (102) et l'arc jusqu'à la pièce.

Patent CA-2360230-A1 (CA)
Title: Micropower capacitance-based proximity sensor
Inventor: HAVEY GARY D
IPC: H03K17/955
Filed: 1999-12-21
Abstract: The present invention is a proximity detector for an electronic device (10).  The proximity detector utilizes two capacitors (20, 22) which share a common electrode (18). The two capacitors (20, 22) are located on the housing (14) of the electronic device (10). The capacitors (20, 22) are arranged so that when the electronic device (10) is used in its normal orientation, a portion of the operator's body will occlude one of the capacitors (20, 22), but not the other. The close proximity of the operator's body will change the electric field surrouding the capacitor. Thus, the capacitance of the occluded capacitor will be different than the unencumbered capacitor. A detection circuit (24) is coupled to the capacitors (20, 22) and to the power supply (15) of the device. The circuit (24) uses very little power, and maintains the electronic device (10) in a standby or powered down mode. Only when the circuit (24) detects a difference in the capacitance generated by the two capacitors (20, 22), will it allow full power to be delivered to the electronic device (10).

Title: Air pressure detection device for wheel
Inventor: YAMAGIWA TOSHIO
IPC: B60C23/04
Filed: 2002-01-10
Abstract: A wheel 14 comprises a disk form wheel 41, a tire 42 fitted to the wheel 41, and a tire tube 43 contained between the wheel 41 and the tire 42, and is provided with an air pressure detection device 50 intermediately disposed between the tire tube 43 and the wheel 41. A metallic line form reception antenna 39 is insert molded in a front fender 32. Since the distance from a transmission means fitted to an air pressure sensor to the reception antenna is reduced, reception sensitivity can be enhanced. In addition, since the reception antenna can be pitched to about the size of the fender, the reception sensitivity can be enhanced.      Further, since jigs for fixing the antenna are needless, a reduction in the number of component parts can be contrived, and the antenna can be fixed without spoiling the appearance.
