Record 4 2009-02-26

English

Subject field(s)
  • Aircraft Propulsion Systems
CONT

The main stage discharge fuel flows to the FMU(flow metering unit), which provides metered fuel through the fuel flow transmitter to the distribution valve and onward through the manifolds to the injectors in the combustion chamber.

French

Domaine(s)
  • Propulsion des aéronefs
CONT

Le carburant est alors refoulé par la pompe vers le dispositif de dosage de carburant (FMU), qui fournit, à travers le débitmètre, un flux de carburant dosé à la vanne de répartition, et de là, dans les rampes d'alimentation des injecteurs situés dans la chambre de combustion.

Record 5 2005-08-16

English

Subject field(s)
  • Fueling Systems (Motor Vehicles)
CONT

Fuel in the D4D is pressurised to an extremely high 135mpa within the "common rail" that feeds all four cylinders (older diesel engines have a separate pipe leading from the pump to each cylinder). The high pressure injection creates better fuel atomisation for complete burning and increased power output. And because there is less fuel wasted through inefficient combustion, the D4D delivers better fuel economy too.

OBS

A common rail engine is designed to supply constant fuel pressure to electronically controlled injectors through a shared fuel reservoir. This means that the fuel supply is not dependent on the engine revs. A common rail system is built around four basic components : a high pressure pump with pressure regulator and inlet metering valve, a rail which contains a pressurised reserve of fuel, injectors which inject precise amounts of fuel into the combustion chamber as required and a Diesel Control Unit-the ’brain’ of the system, which precisely controls injector flow and timing as well as rail pressure while continuously monitoring the operating conditions of the engine.

French

Domaine(s)
  • Alimentation (Véhicules automobiles)
DEF

Rampe d'alimentation commune, maintenue à très haute pression, qui permet une injection directe du carburant dans chaque cylindre du moteur.

OBS

Le secret de la «rampe commune», c'est son tube interposé entre la pompe d'injection et les injecteurs. Alors que dans un système d'injection directe classique, la pression dépend du régime-moteur, cette rampe commune, d'un volume de quelques centimètres cubes, va jouer le rôle de réserve de pression. Ainsi, quel que soit le régime-moteur, le moteur dispose d'une pression pouvant atteindre 1500 bars.

Subject field(s)
  • Animal Feed Processing Equipment
  • Industrial Tools and Equipment
CONT

Magnetic Traps. A set of magnets is located adjacent to the metering augers to attract and prevent iron and steel objects from entering the processing unit without interrupting the normal feed flow or from contaminating ground feeds. [Source : Farmatic, Hammer Mills, p. 2. ]

Domaine(s)
  • Alimentation des animaux (Matériel)
  • Outillage industriel
CONT

Collecteurs aimantés. Pour empêcher les objets en fer et en acier de pénétrer dans l'appareil de traitement sans interrompre l'écoulement normal de l'ingrédient, ainsi que pour prévenir toute contamination des aliments moulus, il y a un ensemble d'aimants pour capter ces objets ferreux à côtés des tarières de mesurage.

Record 7 2003-05-15

English

Subject field(s)
  • Fire Warning Devices
CONT

A pneumatic rate-of-rise spot detector consists of a small dome-shaped air chamber with a flexible metal diaphragm in the base. A small metering hole allows air to enter and exit the chamber during normal rise and fall of atmospheric temperature and barometric pressure. In the heat of a fire, however, the air within the chamber expands faster than it can escape through the metering hole. This expansion causes the pressure within the chamber to increase, forcing the metal diaphragm against contact points in the alarm circuit. An alarm signal to the system control unit results. This type of detector is most often combined in one unit that also has fixed-temperature capability.

OBS

The spot detector monitors smaller areas than the line detector.

French

Domaine(s)
  • Alarme-incendie
CONT

Le détecteur ponctuel thermovélocimétrique pneumatique est constitué d'une petite chambre aérothermique en forme de dôme et d'un diaphragme en métal flexible situé dans la base. Un petit trou permet à l'air d'entrer et de sortir de la chambre aérothermique lors des fluctuations normales de la température et de la pression barométrique. Toutefois, sous l'effet de la chaleur dégagée par un incendie, l'air qui se trouve dans la chambre aérothermique se dilate plus rapidement et ne peut pas s'échapper par le trou. Cette dilatation entraîne une augmentation de la pression à l'intérieur de la chambre aérothermique et force le diaphragme de métal à toucher les points de contact du circuit d'alarme. Un signal d'alarme est alors déclenché à l'unité de contrôle du système. Ce type de déclencheur est souvent combiné à un dispositif qui est également thermostatique.

Record 8 2001-05-15

English

Subject field(s)
  • Scientific Research Equipment
  • Printed Circuits and Microelectronics
CONT

The typical particle counter for metering the amount of particulate matter in clean work station air is an optical assembly. Air is drawn into and through the optical subassembly of the particle counter until a pre-set volume of air has been seen. The particles which are drawn into this optical subassembly cause a pulse of light to be scattered for each particle present. The light pulse is sensed by a detector which converts the pulse to an electrical voltage signal. Each signal is cumulatively counted, for the pre-set volume of air. From the amplitude of the voltage, the size of each particle can be determined. All particle counters consist of three basic subassemblies. These are the optical subassembly which "sees" the particles, a pump subassembly which draws the air stream into and through the optical subassembly, and an electronic subassembly for converting each particle size/unit number to an electrical signal. Also available, usually as an option, is some form of printer.
