Patent CA-2330724-C (CA)
Inventor: POPP ROGER C
IPC: F02M47/04
Filed: 2001-01-10
Granted: 2005-06-14
Abstract: A high pressure gaseous fuel injector for injecting natural gas or other gaseous fuels at high pressures (eg. 300 to 700 psig more or less) into combustion engines for improved efficiency, better performance and reduced environmental emissions.  The fuel injector is powered by hydraulic signals from an electrohydraulic valve.  The fuel injector includes an outer cartridge housing and a universal valve cartridge mounted therein. The cartridge comprises an activator body and a valve body secured together, and the valve body has a gas valve slidable therein. The stroke of the valve is adjustable by controlling the size of shims in the valve body assembly, thereby providing a universal valve cartridge that can be easily adapted to differing fueling requirements for models and sizes of engines. The valve body includes a spring chamber between upper and lower valve guides. The valve body also includes cross-holes to allow cool gaseous fuel to successively pulsate into and out of the spring chamber and thereby cool the exposed portion of the valve between guides, preventing heating of the dynamic gas seal located in the upper guide. An unsealed small clearance between the actuating piston and its bore in the actuator body allows controlled leakage of oil. The leakage of oil lubricates metal to metal contact between the upper guide and the valve and lubricates the dynamic gas seal. Gaseous fuel leakage into the leaked oil is tolerated and any combined oil/gaseous fuel is removed to an external location for separation. Spring washers are used to urge the valve assembly insert against a metal O-ring supported by the outer cartridge body.

Title: Absorbent article having a high coefficient of friction backsheet and a self-release tape tab
Inventor: MOTTA MIRIAM
IPC: A61F13/514
Filed: 2001-04-19
Granted: 2009-12-15
Abstract: The present invention relates to an absorbent article for managing bodily fluids, comprising a high coefficient of friction ("COF") backsheet and at least one tape tab extending therefrom. The tape tab comprises a minimum amount of pressure sensitive adhesive sufficient to maintain the position of the article when a user's undergarments are away from her body. When the undergarments are near her body, the high COF backsheet acts as the predominant means for maintaining the position 3f the article due to normal forces exerted by the user's body and undergarments. When the user wants to remove the article from her undergarments, the tape tab provides additional advantages. The user may grasp the tape tab itself for removing the article as an alternative to grasping a portion of the soiled article. In addition the soiled article may be folded or rolled up, and then held in that configuration with the tape tab, for convenient and discreet disposal.

Granted: 2005-03-22
Abstract: L'invention concerne un régulateur de puissance de crête fonctionnant avec un émetteur-récepteur à accès multiple par répartition de code (ARMC), afin de réduire les pics de puissance de crête dans des signaux de bande de bas, tout en maintenant la cohérence entre la puissance de sortie moyenne et la puissance d'entrée moyenne, par commande des émissions hors bande, et par conservation de la qualité des signaux intra-bande jusqu'à une dégradation acceptable. Les signaux de bande de base en phase et en quadrature sont entrés dans un bloc à retard et dans un prédicteur d'amplitude d'enveloppe appartenant au régulateur de puissance de crête. Ce prédicteur d'amplitude d'enveloppe fournit une estimation de l'amplitude de l'enveloppe, laquelle estimation se produit lorsque les signaux de bande de base émis sont modulés. Cette estimation est soumise à un multiplicateur qui fournit un rapport par division de ladite estimation par une amplitude d'enveloppe maximum. Ce rapport est ensuite introduit dans une table de correspondance qui fournit un facteur d'échelle suffisant pour réduire les pics de puissance de crête. Ce facteur d'échelle est ensuite introduit dans un régulateur de puissance moyenne facultatif, qui produit une valeur de gain instantanée, suffisante pour maintenir le niveau de puissance de sortie moyen au niveau de puissance d'entrée moyen. La valeur du gain est appliquée à deux multiplicateurs qui sont également entrés avec des versions différées des signaux d'entrée de bande de base en phase ou en quadrature. Les sorties de ces deux multiplicateurs, après avoir été filtrées par des filtres passe-bas afin d'éliminer les émissions hors bande provoquées par la mise à l'échelle, se retrouvent en sortie du régulateur de puissance de crête. Ces sorties de puissance de crête réduites présentent une échelle réduite quelconque de pics de puissance de crête, et permettent cependant de conserver la puissance moyenne constante du prédicteur d'amplitude d'enveloppe.

Abstract: In prior art embodiments of displacement machines for compressible media, single thread twin helical rotors function with a continuously diminishing gradient to obtain internal compression. In some cases, this effect is amplified or superseded by the variation of the front profiles. The demand for compact pumps with rotors which are as a short as possible and the frequent process-related demand for quicker disassembly of the housing for cleaning purposes place limits on the wrapping angle or on the variation of the front profiles, which in turn leads to extreme gradient ratios or to insufficient compression rates. The invention solves these problems by using helical rotors (2) with an optimized, non-monotonous gradient (.DELTA.w1, .DELTA.w3) and an optional front profile variation with constant diameters. The displacement capacity is improved without altering the space requirements, and compression rates of 3.0 and more are easily attained using only four wrappings. Displacement machines equipped with twin helical rotors of this type offer optimal ratios with regard to energy demands, temperature, installation space and servicing, and can be used in the fields of chemicals and semiconductor technology.

Abstract: An optical transmission fiber for use in a metropolitan or access network is disclosed. The transmission line includes a fiber being single mode at a first operating wavelength of around 1310 nm and a second operating wavelength of around 1550 nm. The dispersion of the fiber is negative at one of the first and second operating wavelengths and positive at the other of the first and second operating wavelengths, with an absolute value of between about 5 ps/nm/km and 15 ps/nm/km. The fiber also has a zero dispersion wavelength that is located between the first and second operating wavelengths, and an effective area at a wavelength around 1550 nm greater than about 60 µm2. The cabled fiber has a cutoff wavelength less than about 1300 nm. The fiber allows wavelength division multiplexing (WDM) operation in both the bands (1310 nm and 1550 nm) by reducing nonlinear effects such as four-wave mixing (FWM).

Abstract: An improved brake lathe station has an on-vehicle brake lathe and a lift with one or more support posts for raising a vehicle. A support structure is provided to support the lathe while allowing it to be moved with respect to a horizontal plane about the vehicle to assist the lathe operator in positioning the lathe with respect to wheel hubs of the vehicle. The lathe is preferably connected to the support structure by an adjustable coupling which allows vertically tilting a lathe rotation axis of the lathe, as well as allowing rotation of the lathe substantially about its lathe rotation axis. Preferably, the lathe can also be moved with respect to a vertical plane. To prevent transmission of vibrations during the machining process, it is preferred for the lathe to be floated with respect to the support structure while the lathe is mounted on the wheel hub. The coupling can be designed to allow attaching a dolly to the lathe while it is still supported by the support structure, and to allow the lathe thereafter to be released from the support structure so the lathe can be moved on the dolly.
