Record 2 2016-03-07

English

Subject field(s)
  • Mineral Processing (Metallurgy)
  • Processing of Mineral Products
DEF

A classifier for separating fine-size solids from coarser solids in a wet pulp consisting of an interrupted-flight screw conveyor, operating in an inclined trough.

CONT

Spiral classifiers... do not normally set up a turbulent stirring action in the classifying pool, but cross-pieces can be bolted to the spiral shoes to produce this.... As settled sands emerge from the "V" end of the pool, they bring with them some trapped or "drag-out" slime which should properly have overflowed at the weir. Washing sprays are often used to return this material to the pool. [The] spiral classifier... carries its sands upward on the rising side of the helix, so that sprays can be used at any point and there is a good channel for running their washed product straight down to the pool.

French

Domaine(s)
  • Minéralurgie (Métallurgie)
  • Préparation des produits miniers
DEF

Classificateur hydraulique dans lequel les sables sont remontés et extraits de l'appareil à l'aide d'une vis de transport.

CONT

Classificateurs à drainage mécanique. Le classificateur à vis utilise la partie inférieure du bac élargie avec débordement pour constituer une zone de sédimentation sans turbulence, dite «pool de classification». [...] Les particules décantées sont brassées par la partie de la spirale plongeant dans le pool de classification avec élimination des indésirables évacuées par le seuil de débordement; puis elles sont entraînées vers le haut en subissant un essorage jusqu'à la sortie supérieure.

Record 3 2008-05-30

English

Subject field(s)
  • Satellite Telecommunications
DEF

Volume capacity assigned to RCSTs [return channel via satellite terminals] from capacity, which would otherwise be unused.

CONT

Free Capacity Assignment (FCA). CRA [continuous rate assignment] and FCA can also be viewed as two mechanisms to grant dynamically, capacity to a terminal, without requests being made from that terminal. This does not exclude the possibility that requests may have been made at a higher level than the terminal.

OBS

It should be noted that the term "free" in FCA refers to "spare" system capacity and has no bearing on accounting.

Record 4 2004-09-24

English

Subject field(s)
  • Atmospheric, Climatic and Meteorological Phenomena
DEF

Leader stroke of a lightning discharge other than the first in the series of a compound discharge, in which the ionized channel is established in a single jump.

CONT

If a residual charge is available at the top of the channel, a charge called a dart leader may propagate down the first stroke channel. The dart leader initiates the second, third and fourth return strokes, if any.

CONT

... the dart leader moves along the same path as the original stepped leader, but this time without forking or branching.

CONT

The first stroke begins with a stepped leader followed by an intense return stroke which is the principal source of luminosity and charge transfer. Subsequent strokes begin with a dart leader followed by another return stroke.

OBS

The dart leader derives its name from its appearance on photographs taken with streak cameras.

French

Domaine(s)
  • Phénomènes météorologiques, climatiques et atmosphériques
DEF

Traceur d'une décharge électrique autre que la première de la série d'une décharge composée, dans laquelle le canal ionisé s'établit d'un seul coup.

CONT

Après la décharge de retour, l'éclair peut s'arrêter là. Mais si la charge est suffisante dans le nuage, un traceur de dard peut retourner du nuage au sol par un circuit direct. Ce traceur de dard déclenche une deuxième décharge de retour. Il peut y avoir plusieurs décharges de retour dans un éclair, en moyenne 3 ou 4, avec entre 40 et 80 millisecondes entre chaque décharge.

Record 5 2004-09-24

English

Subject field(s)
  • Atmospheric, Climatic and Meteorological Phenomena
DEF

The narrow path of ionized air in which the lightning discharge current flows.

CONT

The ionized channel is a conducting path for the lightning discharge.

CONT

Cloud-to-ground [discharge. ]... Once a sufficiently high voltage difference exists for electrical breakdown to begin in the cloud, a streamer of electrons develops. This, in turn, can become a "stepped leader, "which approaches the earth in a series of rapid steps... The stepped leader produces an ionized channel(molecules in its path are stripped of electrons) and tends to follow a downward branching path. As soon as one of the branches is within five to 50 meters of the surface, another streamer advances upward to meet it along the path of least resistance(often through tall and pointed objects). Now an ionized path a few centimeters in diameter connects earth with cloud. Next, the "return stroke, "which carries a surge of current, travels up the ionized channel, lighting up the paths taken by the stepped leader.

OBS

Channel... It is illuminated brightly during the return stroke.

Quand la décharge pilote atteint [...] par bonds successifs les derniers décamètres qui la séparent de la Terre, une décharge partant [...] du sol [...] va à la rencontre de la décharge pilote venant du nuage, et un canal ionisé relie ainsi une petite zone de la charge du nuage au sol.

English

Subject field(s)
  • Satellite Telecommunications
DEF

Volume capacity, which is requested dynamically by the RCST [return channel via satellite terminal].

CONT

Volume Based Dynamic Capacity (VBDC). VBDC should be used only for traffic that can tolerate delay jitter, such as the Unspecified Bit Rate (UBR) class of ATM [asynchronous transfer mode] traffic or standard IP [Internet Protocol] traffic.

Subject field(s)

DEF

Rate capacity which is requested dynamically by the RCS-[return channel via satellite] Terminal(RCST).

CONT

Rate Based Dynamic Capacity (RBDC). RBDC should be used for variable rate traffic which can tolerate the MSL [minimum scheduler latency] delay. A typical application for RBDC over a GEO [geostationary] satellite could be the ATM [asynchronous transfer mode] Available Bit Rate (ABR) class.

Record 8 2004-03-15

English

Subject field(s)
  • Satellite Telecommunications
CONT

Absolute Volume Based Dynamic Capacity(AVBDC). AVBDC is similar to VBDC [volume based dynamic capacity] and should be used instead of VBDC when the RCST [return channel via satellite terminal] senses that a VBDC request might be lost.
