Valve rotation has an overall positive effect on valve life. Rotation provides improved temperature distribution in the valve head and a mild scraping action that cleans the valve interface of any crushed combustion deposits.  1, fiche 1, Anglais, - valve%20rotation

La rotation des soupapes assure une répartition uniforme de la température autour du siège et améliore la longévité en réduisant les distorsions locales et en évitant le passage des gaz dans le carter et la formation de craquelures sur la surface d'étanchéité. La rotation réduit en outre l'usure des autres composants en contact direct avec la soupape.  1, fiche 1, Français, - rotation%20de%20soupape

Un mode opératoire très simple (méthode des béchers) a été mis au point par A. Avy et R. Raillères. Dans une colonne de liquide "h", on introduit un poids "p" de poudre, on agite pour rendre la suspension homogène, on laisse au repos un temps "t" (10 secondes par exemple) puis on décante. Si 10 secondes est le temps nécessaire pour que les particules de 10 [microns] tombent de la hauteur "h", le sédiment "S" renfermera toutes les particules de 10 [microns] et plus; (...)  1, fiche 2, Français, - m%C3%A9thode%20des%20b%C3%A9chers

A bleed air manifold serves as a collection/distribution point for regulated bleed air from either engine. From the manifold, bleed air is distributed to the cabin for pressurization and heating via the flow control valve. The bleed air manifold also supplies the various other pneumatic systems previously identified.  2, fiche 4, Anglais, - bleed%20air%20manifold

The helmet is a clear plastic pressure bubble that allows the crew member to see in the dark. It is fitted with a neck disconnect ring and ventilation distribution pad. A valve was built in to remove carbon dioxide and to act as a backup purge valve to use with the secondary oxygen pack. There is also an Extravehicular Visor Assembly that attaches to the helmet. It has a gold visor to allow the astronaut to work in the presence of the Sun.  2, fiche 5, Anglais, - helmet

A supercharger which is located between the carburetor outlet and the intake manifold of the engine is called an internal supercharger. A supercharger thus located serves to provide a uniform distribution of the fuel-air charge to the various cylinders, as well as to increase the density of the charge. Maintaining a high manifold pressure ahead of the intake valves allows the use of "valve overlap" in the engine, so that the intake valve opens just before the exhaust valve closes at the end of the exhaust stroke. This allows the compressed mixture from the intake manifold to scavenge the spent gases out of the clearance volume of the cylinder and also tends to improve the cooling of the exhaust valve. This cooling is of particular importance when operating at "military" or "take-off" power. With no supercharging between the carburetor and the intake valves, "valve overlapping" would permit exhaust gases to flow back into the intake manifold. This would cause backfiring and dilution of the next charge of mixture with burned exhaust gases.  4, fiche 6, Anglais, - internal%20supercharger

There is another difference between internally driven superchargers and turbochargers ... The internal supercharger compresses the fuel/air mixture after it leaves the carburetor or fuel metering device, while the turbocharger compresses the air before it is mixed with metered fuel.  2, fiche 6, Anglais, - internal%20supercharger

When the valve is open, the melting or plasticizing cylinder pushes the material into the nozzle end of the pot, forcing the plunger back. When the plunger moves back an experimentally predetermined distance, the filling stops and the valve is closed, because the backward motion of the plunger actuates a limit switch. At the appropriate time in the cycle the material is injected into the mold from the second cylinder, the so-called shooting cylinder or pot. This method of operation gives much better mixing of the plastic, more even temperature distribution, and better control of speed, pressure, and the amount of material. This type machine is called a preplasticizing machine.  2, fiche 7, Anglais, - preplasticizing%20press

Cylindre de décantation. Principe: si on laisse sédimenter une suspension uniforme pendant "t" secondes et qu'ensuite on décante à une profondeur "h" centimètres, le liquide non décanté contient toutes les particules qui ont des vitesses de chute supérieures à "h/t", plus les particules de vitesse inférieure à "h/t" qu'il contenait déjà. (...) L'appareillage est fort simple. Un récipient de un litre environ, de hauteur 12,5cm muni d'un siphon à 25mm du fond, contient la suspension; la fraction qui doit être décantée est soutirée par siphon ou robinet.  1, fiche 8, Français, - cylindre%20de%20d%C3%A9cantation

Ventilating air for cooling the generator, the oil cooler, and the APU compartment is obtained from the aft accessory compartment and is ducted through a fire isolation valve into the APU enclosure.... The remainder of the ventilating air is ducted into the APU-driven cooling fan which forces the air through the APU oil cooler into the general compartment. Some of the fan air is diverted from the oil cooler into a distribution duct which directs cooling air to the APU enclosure. The compartment is vented through a sound suppressing muffler and thence overboard by an air discharge duct.  2, fiche 9, Anglais, - discharge%20duct
