Record 4 2001-07-03

English

Subject field(s)
  • Launching and Space Maneuvering
  • Orbital Stations
CONT

The description of the Station's flight attitude(orientation relative to the plane of its orbit) is referenced to local-vertical/local-horizontal(LVLH) axes that are fixed with respect to the Station's near-circular orbit(i. e., not to the physical Station). The LVLH origin is at the Station's center-of-mass; the z-axis points radially toward the Earth's center(or toward the nadir direction), the x-axis points along the orbital velocity vector(the ram direction, with wake being opposite), and the y-axis completes the right-handed triad. The flight attitude of the Station is then described using a second, Station-fixed, coordinate system whose orientation relative to LVLH is specified using the Eulerian angles of yaw, pitch and roll. Several Station-fixed coordination systems are defined. The most widely used is the Space Station Reference Coordinate System,... in thich the positive x-axis points along the axis of the U. S. lab away from the Zarya and Service Modules; the positive y-axis points starboard along the main truss, and positive z completes a right-handed coordinate system.

OBS

Station’s flight attitude: term officially approved by the International Space Station official approval Group (ISSOAG).

French

Domaine(s)
  • Lancement et manœuvres dans l'espace
  • Stations orbitales
CONT

Iouri Onoufrienko et Dan Bursch, qui avaient enfilé des combinaisons spatiales russes Orlan, ont installé six écrans de protection autour des micropropulseurs qui servent à contrôler l'attitude de la Station et qui sont situés à l'arrière du module Zvezda.

OBS

attitude de la Station : terme uniformisé par le Groupe de travail de la terminologie de la Station spatiale internationale (GTTSSI).

Record 5 1998-06-22

English

Subject field(s)
  • Plastics Manufacturing
  • Presses (Machinery)
DEF

The upper structure of a vertical hydraulic press. In an upstroke press, the main head carries a fixed table or platen, whereas in a downstroke press, it carries the cylinder casting and ram.

OBS

main head: term standardized by ISO.

Key term(s)
  • upper platen
  • upper plate
  • top plate
  • top platen

French

Domaine(s)
  • Plasturgie
  • Presses (Machines)
CONT

Plateau mobile : Dans une presse à plateaux multiples, plateau situé entre le plateau supérieur et la table de presse, dont le mouvement est indépendant.

OBS

plateau supérieur; corps de presse : termes normalisés par l'ISO.

Record 6 1997-11-17

English

Subject field(s)
  • Plastics Manufacturing
OBS

For larger parts, the ram accumulator is the machine of choice. This type of machine is used to make parts weighing up to 50 pounds. Typical applications include industrial parts, shipping containers, and toys. The size of the extruder is independent of accumulator size, and in some cases more than one extruder is used. The main disadvantage of the system is that the first material to enter the accumulator is the last to leave, making the process unsuitable for heat-sensitive materials.

OBS

downstroke press : hydraulic press in which the main ram is above the moving table and operates downward.

French

Domaine(s)
  • Presses (Machines)
  • Plasturgie
OBS

presse descendante : presse hydraulique dans laquelle le piston principal est situé au-dessus du plateau, la pression étant appliquée par un mouvement descendant du piston.
