  2. Pneumatic trough - Wikipedia

    en.wikipedia.org/wiki/Pneumatic_trough

    Pneumatic trough, and other equipment, used by Joseph Priestley. The bottle is filled with water, inverted, and placed into the pneumatic trough already containing water. The outlet tube from the gas-generating apparatus is inserted into the opening of the bottle so that gas can bubble up through it, displacing the water within. [4]

  3. Beehive shelf - Wikipedia

    en.wikipedia.org/wiki/Beehive_shelf

    The right-hand drawing is about half the scale of the others and shows the shelf in use inside a pneumatic trough. A beehive shelf is a piece of laboratory equipment, usually of pottery, used to support a receiving jar or tube while a gas is being collected over water with a pneumatic trough. It is used so that when the gas emerges from the ...

  4. Pipe plug - Wikipedia

    en.wikipedia.org/wiki/Pipe_plug

    Pipe plugs provide a trench-less method for the maintenance of drains and sewers, and construction and testing of non-pressurized gravity pipelines. There are three main purposes of pipe plugs. These are temporary sealing or stopping the fluid flow in a pipeline, leak testing and by-passing the flow.

  5. Shotcrete - Wikipedia

    en.wikipedia.org/wiki/Shotcrete

    Gunite was originally a trademarked name that specifically referred to the dry-mix pneumatic cement application process. In the dry-mix process, the dry sand and cement mixture is blown through a hose using compressed air, with water being injected at the nozzle to hydrate the mixture, immediately before it is discharged onto the receiving surface.

  6. Pneumatic chemistry - Wikipedia

    en.wikipedia.org/wiki/Pneumatic_chemistry

    Robert Boyle's air pump. In the history of science, pneumatic chemistry is an area of scientific research of the seventeenth, eighteenth, and early nineteenth centuries. . Important goals of this work were the understanding of the physical properties of gases and how they relate to chemical reactions and, ultimately, the composition of

  7. 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 ...

  8. Eudiometer - Wikipedia

    en.wikipedia.org/wiki/Eudiometer

    Landriani used a pneumatic trough in the form of a tall, graduated cylinder over water. As it measured the salubrity of air, he called it a eudiometer [ 1 ] An associate of Moscati's, Felice Fontana also designed a eudiometer on the same principles and quantified the salubrity of the air.

  9. Pneumatic tool - Wikipedia

    en.wikipedia.org/wiki/Pneumatic_tool

    Drilling a blast hole with a pneumatic drill (jackhammer). A pneumatic tool, air tool, air-powered tool or pneumatic-powered tool is a type of power tool, driven by compressed air supplied by an air compressor. Pneumatic tools can also be driven by compressed carbon dioxide (CO 2) stored in small cylinders allowing for portability. [1]
