Definition of Vacuum tube
Vacuum tube 2. The condition of rarefaction, or reduction of pressure
below that of the atmosphere, in a vessel, as the
condenser of a steam engine, which is nearly exhausted of
air or steam, etc.; as, a vacuum of 26 inches of mercury,
or 13 pounds per square inch.
Vacuum brake, a kind of continuous brake operated by
exhausting the air from some appliance under each car, and
so causing the pressure of the atmosphere to apply the
Vacuum pan (Technol.), a kind of large closed metallic
retort used in sugar making for boiling down sirup. It is
so connected with an exhausting apparatus that a partial
vacuum is formed within. This allows the evaporation and
concentration to take place at a lower atmospheric
pressure and hence also at a lower temperature, which
largely obviates the danger of burning the sugar, and
shortens the process.
Vacuum pump. Same as Pulsometer, 1.
