Record number: 1, Textual support number: 1 CONT

Rotary vane vacuum pumps are built in single-and two-stage versions. Two-stage pumps achieve lower ultimate pressures than single-stage pumps. Moreover, the effects of the gas ballast on the ultimate pressure are lower, as the ballast gas is only admitted in the second stage.  1, record 1, English, - rotary%20vane%20vacuum%20pump

Balloons can be captive, free-floating, or powered. ... A free-floating balloon travels wherever it is blown by the wind. The balloon pilot can control the vertical movement of a piloted, free-floating balloon but cannot steer it. However, the pilot can control the course of a balloon flight to some degree by rising or descending into a layer of wind that is blowing in the desired direction.  5, record 2, English, - free%20balloon

Le ballon libre. [...] En montant, le ballon traverse des couches atmosphériques de masse volumique décroissante; la force ascensionnelle diminue, et il finit par atteindre une position d'équilibre; pour continuer à monter, il faut alléger le ballon: l'aéronaute jette alors du lest. S'il veut descendre, il laisse échapper du gaz en ouvrant la soupape.  3, record 2, French, - ballon%20libre

La montgolfière a été le premier moyen de transport inventé par l'homme pour se déplacer dans les airs. [...] Le ballon libre, appelé alors «globe aérostatique» ne trouvait guère d'utilité, car il se contentait de dériver au gré du vent. C'est donc à diriger les ballons, c'est-à-dire les conduire, que l'on va travailler, mais il faudra un siècle pour y parvenir.  2, record 2, French, - ballon%20libre

Agencies working for NASA use this term for a lighter-than-air aircraft designed to explore the planets. An aerobot is a helium-filled balloon fitted with heaters that are powered by solar cells. During the day, solar energy will heat the helium and give it extra buoyancy; at night, the balloon will drop to lower altitudes or even touch the ground. A limitation of the design is that its movements cannot be fully controlled, though it may have some ability to dictate its altitude, perhaps through dropping ballast, releasing gas or managing its temperature. A big advantage of this design is that it doesn’t need fuel, which is expensive to transport and which runs out all too soon. Unlike satellites, aerobots fly in the atmosphere, so allowing experiments to be carried out on its chemistry. They can also view and record the ground from much lower altitudes than is possible with satellites. NASA plans to send a device of this sort to Mars in 2003, and possibly later to Titan, Venus and Jupiter.  2, record 5, English, - aerobot
