Abstract: A fuel injector for injecting fuel into a combustion chamber of an internal combustion engine has a body containing a mechanism that is operable to cause fuel to be injected out of the body and into the combustion chamber. An electric actuator operates the mechanism to initiate a fuel injection from the body when an initiating electric signal for initiating a fuel injection is applied to the electric actuator and to terminate the fuel injection when the electric signal changes to a terminating electric signal for terminating the fuel injection. The injector has an identity circuit that possesses an identity characteristic identifying a calibration category into which the fuel injector has been previously categorized based on data obtained from actual operation of the fuel injector. In some embodiments the identity circuit is electrically connected in shunt with the electric actuator and imposes no significant effect on the response of the fuel injector to the initiating and terminating electric signals. In others, it is connected between engine ground and one actuator terminal.

Abstract: In a method of spectrochemical depth-profile analysis of heterogeneous materials, a first burst of ablation laser pulses in a first beam is directed at a sample to form an ablation crater. A second single pulse or burst of laser pulses in a second beam having a smaller width than said first beam is then directed at the bottom of the crater so as to create a plasma that emits radiation representative of a component in the sample without a significant contribution from the walls of the ablation crater. The intensity of radiation from the plasma is measured and the concentration of the selected component is determined from the intensity of the radiation. The depth at which the measurement is taken is then evaluated and the above steps repeated to determined the evolution of concentration of said selected component as a function of depth.

Title: Polarization-combining fused-fiber optical coupler and method of producing the same
Inventor: DION BRUNO Y
IPC: G02B6/28
Filed: 2001-08-08
Abstract: A polarization-combining fused-fiber optical coupler is made of polarization maintaining (PM) fibers spliced to non-birefringent single mode (SM) fibers which are fused and drawn near the splicing to form a coupler with an adiabatic tapered profile. The linearly polarized light injected into PM fibers travels through the coupler where the power of the two polarizations is combined and transmitted to one output fiber. The method for producing such coupler involves splicing a pair of PM fibers to a pair of SM fibers, then injecting linearly polarized light into each PM fiber and fusing and drawing SM fibers to form an adiabatic coupler with maximum power transmission at a desired wavelength going to only one output fiber.

Abstract: In a method for reducing hydrogen chloride emissions from an asphalt air- blowing process, an asphalt is subjected to an air-blowing process where air  is bubbled through hot asphalt to raise the softening point of the asphalt. The fumes from the air-blowing process are bubbled through a liquid seal in a knockout tank before going to an incinerator and finally being emitted to th e atmosphere. The knockout tank normally operates to condense oil in the fume stream, and the liquid seal is composed of this oil, as well as some of the water evolved in the air-blowing process. When using ferric chloride or ferrous chloride as a catalyst in the air-blowing process, the fume stream contains significant levels of hydrogen chloride. In this invention, a chemical modifier is added to the process oil and water seal in the knockout  tank prior to the start of the process in order to reduce the amount of hydrogen chloride in the emitted fume stream by at least 25% by weight compared to the same process without the addition of the chemical modifier.< /SDOAB>

Abstract: Where a submarine wellhead is coupled to a floating vessel by a riser in the form of a flexible hose, vessel movements subject the riser to excessive strains where the riser is tethered to the vessel. In accordance with the invention, these strains are reduced by pivoting the riser tether about a horizontal axis, and optionally also about a vertical axis. Giving the riser tether at least one degree of rotational freedom is surprisingly beneficial in reducing riser strains, and consequently in reducing the probability of premature failure of the riser.

Abstract: A lift assembly for an axle of the trailer of a semi-trailer or of another vehicle such as a straight truck, is mounted generally adjacent to and beneath each suspension beam of the axle/suspension systems of the trailer or other vehicle. The manner of mounting the lift assembly generally adjacent to and beneath the beam provides sufficient clearance for concurrent disposition of a dual service/parking brake chamber adjacent to and beneath the beam. The location and orientation of the axle lift assembly, relative to radial lines emanating from the pivot point of the suspension beam, facilitates the application of efficient lift forces to the beam by the lift assembly, which in turn results in less wear to an air chamber of the lift assembly. The air chamber of the lift assembly can be quickly and easily removed and reinstalled to allow for replacement of the dual brake chamber.

Filed: 2001-07-17
Abstract: Cette invention concerne un procédé et un dispositif de gestion des encombrements par domaine permettant de détecter et de réguler des encombrements dans un réseau à services différenciés. Ce système fait intervenir une technique d'amélioration de le détection aléatoire précoce (improvRED) pour la détection d'encombrements au niveau des routeurs centraux et des files d'attente simples (token bucket filters) pour la régulation du trafic au niveau des noeuds d'entrée. De plus, improvRED assure une commande de rétroaction. ImprovRED fait intervenir trois seuils pour la détection d'encombrements: un seuil minimum, un seuil maximum et un seuil de rétroaction dont la valeur se situe entre les seuils minimum et maximum. Chaque fois que la taille moyenne de la file d'attente est supérieure au seuil minimum, mais inférieure au seuil de rétroaction, tous les paquets sortants sont repérés en conséquence et signalent l'apparition possible d'une période d'encombrement. Lorsque la taille moyenne de la file d'attente est supérieure au seuil de rétroaction (mais inférieure au seuil maximum), des paquets sont abandonnés selon des critères de probabilité et tous les paquets sortants sont repérés en conséquence de manière à rendre compte de cette phase d'abandon. Lorsque la taille moyenne de la file d'attente est supérieure au seuil maximum, tous les paquets entrants sont abandonnés. On utilise une rétroaction, sous forme d'un message de notification d'encombrement local, pour indiquer aux noeuds d'entrée l'apparition vraisemblable d'un encombrement. Les noeuds d'entrée réagissent immédiatement à la notification d'encombrement en régulant en conséquence leurs taux de trafic respectifs (c'est-à-dire le volume de paquets qu'ils injectent dans le réseau à services différenciés). Le volume de trafic (ou de paquets de données) injecté dans le coeur du domaine à services différenciés est déterminé par une file d'attente simple à chacun des noeuds d'entrée.

Abstract: A single air spring (36) positioned under one side of a vehicle (10) provide s side to side loading of the vehicle (10). Main springs (30) support the vehicle (10) above a pair of coaxial wheels or coaxial wheel sets. An auxiliary inflatable air spring (36) is positioned to provide additional support to the vehicle (10) above one of the wheels. Deflection of the main springs (30) from a norm or index is indicated by movement of tie rods (60 a nd 64) mounted from the wheels, axle (22), or base of the main springs relative  to the suspended portion of the vehicle. One tie rod is directly linked to a  free end of an equalizer lever (58) whereby the equalizer lever moves in the  same direction as the tie rod. The second tie rod is coupled to the remainin g free end of the equalizer lever by a rotatable rod (62), whereby the appropriate end of the equalizer lever moves in the direction opposite to th e tie rod. The equalizer lever (58) is suspended at its center from an actuati on lever for a valve used to control inflation and deflation of the auxiliary a ir spring (36). The actuation lever (46) has a pivot axis fixed with respect to  the suspended vehicle (10), so movement the center point of the equalizer lever (58) results in movement of the actuation lever (46). The direction of  movement of the actuation lever results in valve action to inflate, deflate,  or hold the pressure in the auxiliary air spring (36).
