In order to minimize the plasma loss arising from interactions with background gas particles, the plasma is contained in an ultra-high vacuum system. The high vacuum is obtained by using turbo-molecular pumps for the initial vacuum and liquid helium cryopumps for the pumping to very low pressure.  1, record 1, English, - ultra%2Dhigh%20vacuum%20system

In a skidding turn, the gyro precesses towards the inside of the turn. After return on the aircraft to straight and level flight, the instrument shows a turn in the direction of the skid. In a normal turn, the gyro precesses towards the inside of the turn. The precession error is quickly corrected by the erecting mechanism.  2, record 2, English, - erecting%20mechanism

The only really tricky part of the attitude indicator is its erecting mechanism. When power(vacuum) is first applied to the instrument, the mechanism quickly erects the gyro spindle to plumb-vertical in order to align the artificial horizon with the natural horizon. In flight, the erecting mechanism continually compensates the gyro for precession errors in order to keep it aligned throughout the course of a long flight. The design of the erecting mechanism is quite clever. In an air-driven attitude gyro, there are "pendulous vanes" suspended from pivots attached to the lower portion of the sealed gyro housing, one vane for each exhaust port. The vanes are positioned so that, when the gyro is erect, each vane half-covers its associated exhaust port. If the gyro tilts so that its axle is not plumb, the pendulous vanes shift so that one exhaust port is more-than-half-covered and the opposite exhaust port is less-than-half-covered. The resulting imbalance of discharge air exerts a force on the rotor housing at right angles to the direction of tilt, causing the gyro to precess to the erect position. As soon as the gyro is erect, the pendulous vanes return to a balanced condition to remove the precessing force. Pure magic! The erecting mechanism can erect the gyro quite quickly at initial power-up because the gyro doesn’t exhibit much gyroscopic rigidity at low rotor RPMs. Typically, the horizon bar becomes level within the first 10 or 15 seconds, and then its oscillations(caused by precessional nutation of the gyro) are damped out within a minute or so as the rotor comes up-to-speed.  3, record 2, English, - erecting%20mechanism

Vacuum Exhaust System(Waste Gas). All of the laboratory modules contain the plumbing to support a waste gas exhaust system that is vented to space. A 2. 5 cm(1 in.) diameter gas line connected to this exhaust system is provided at each of the ISPR [International Standard Payload Racks] locations. The pressure allowed into the waste gas line is 275. 8 kPa(40 psia). The temperature of the exhaust waste gas is allowed to be be between 15. 6-45°C(60-113°F). The waste gas system can reach pressures of 1 x 10 [minus³] torr(1. 9 x 10^{minus 5} psia) in less than two hours for a single payload volume of 100 liters(3. 5 ft³) at an initial pressure of 101. 4 kPa(14. 7 psia). The waste gas system is a shared and scheduled resource that can only be operated at one ISPR location within each module at a time. This requirement is to prevent cross contamination of payloads and incompatible mixtures of waste gas constituents. The types of waste gas constituents allowed must be compatible with the wetted materials of the module waste gas system.  3, record 4, English, - waste%20gas%20exhaust%20system

Referred to unit of mass of the solid, the difference(at constant temperature) between the enthalpy of a solid completely immersed in a wetting liquid, and that of the solid and the liquid taken separately. It must be specified whether the solid in the initial state is in contact with vacuum or with the vapour of the liquid at a given partial pressure. Measurements of the enthalpy of wetting of a solid equilibrated with varying relative pressures of the vapour of a pure wetting liquid may be used to derive the differential enthalpy of adsorption of the vapour.  1, record 6, English, - enthalpy%20of%20wetting

For simple thickening of very dilute stocks up to 12% consistency, multidisc thickeners... can be used. A fiber mat forms on the face of each sector as it submerges in the vat of stock. After complete submergence, vacuum is applied and more pulp is deposited while filtrate is drawn through the mat. The initial filtrate is relatively cloudy and can be segregated(by the action of the end valve) for dilution uses. The later(clear) filtrate is sufficiently free of fiber to be used for shower water. Following emergence from the vat, the pulp mat is further dewatered and finally removed from the filter media by a knockoff shower. Multidisc thickeners are most commonly used as save all devices, i. e., to recover fine fibers from white water and reuse the water.  1, record 7, English, - multidisc%20thickener

Pour obtenir un épaississage à une concentration ne dépassant pas 12 %, on peut faire appel à des épaississeurs à disques [...] Un matelas fibreux se forme à la surface de chacun des segments à mesure que ceux-ci plongent dans la cuve de pâte. Après immersion complète, un vide est appliqué qui entraîne un dépôt supplémentaire de pâte, tandis que le filtrat est aspiré à travers le matelas. Le premier filtrat est relativement trouble et peut être isolé (par l'appareil de robinetterie d'extrémité) aux fins de dilution. Le filtrat subséquent (plus clair) possède une teneur en fibres suffisamment faible pour servir d'eau de rinçage. À sa sortie de la cuve, la couche de pâte continue d'être épaissie, puis est enfin détachée du disque filtrant au moyen d'un rinceur de choc.  1, record 7, French, - %C3%A9paississeur%20%C3%A0%20disques
