  2. Pneumatic chemistry - Wikipedia

    en.wikipedia.org/wiki/Pneumatic_chemistry

    [2] Van Helmont (1579 – 1644) is sometimes considered the founder of pneumatic chemistry, as he was the first natural philosopher to take an interest in air as a reagent. [3] Alessandro Volta began investigating pneumatic chemistry in 1776 and argued that there were different types of inflammable air based on experiments on marsh gases. [4]

  4. Aerodynamic levitation - Wikipedia

    en.wikipedia.org/wiki/Aerodynamic_levitation

    Sample is heated by a CO 2 laser and temperature is measured from sample brightness by a pyrometer. Here a light ball hovers in an air stream generated by a ventilator in the square box. Aerodynamic levitation is the use of gas pressure to levitate materials so that they are no longer in physical contact with any container.

  5. Pneumatics - Wikipedia

    en.wikipedia.org/wiki/Pneumatics

    Pneumatics (from Greek πνεῦμα pneuma 'wind, breath') is the use of gas or pressurized air in mechanical systems. Pneumatic systems used in industry are commonly powered by compressed air or compressed inert gases. A centrally located and electrically-powered compressor powers cylinders, air motors, pneumatic actuators, and other ...

  6. Working fluid - Wikipedia

    en.wikipedia.org/wiki/Working_fluid

    In pneumatics, the working fluid is air or another gas which transfers force between pneumatic components such as compressors, vacuum pumps, pneumatic cylinders, and pneumatic motors. In pneumatic systems, the working gas also stores energy because it is compressible. (Gases also heat up as they are compressed and cool as they expand.

  7. Air-operated valve - Wikipedia

    en.wikipedia.org/wiki/Air-operated_valve

    An air-operated valve, also known as a pneumatic valve, is a type of power-operated pipe valve that uses air pressure to perform a function similar to a solenoid. As air pressure is increased, the compressed air starts to push against the piston or diaphragm walls which causes the valve to actuate. Whether the valve opens or closes depends on ...

  8. Pneudraulics - Wikipedia

    en.wikipedia.org/wiki/Pneudraulics

    Derived from the words hydraulics and pneumatics, pneudraulics is the term used when discussing systems on military aircraft that use either or some combination of hydraulic and pneumatic systems. [1] The science of fluids made of both gas and liquid.

  9. Pneumatic trough - Wikipedia

    en.wikipedia.org/wiki/Pneumatic_trough

    Four items are required for gas collection with a pneumatic trough: [2] The trough itself, which is a large glass dish or a similar container. A gas bottle (or bulb), to hold the gas collected. A way to support the gas bottle or bulb, such as a beehive shelf or a hanger (as with Stephen Hales' design). A liquid in the trough.
