2. Rutherford (rocket engine) - Wikipedia

   en.wikipedia.org/wiki/Rutherford_(rocket_engine)

   It uses LOX (liquid oxygen) and RP-1 (refined kerosene) as its propellants and is the first flight-ready engine to use the electric-pump-fed cycle. The rocket uses a similar engine arrangement to the Falcon 9 ; a two-stage rocket using a cluster of nine identical engines on the first stage, and one vacuum-optimized version with a longer nozzle ...

3. Miniature mass spectrometer - Wikipedia

   en.wikipedia.org/wiki/Miniature_mass_spectrometer

   Mini mass spectrometers relying on miniature 18 mm rods transpector quadrupole for mTorr pressure operation, a miniature turbo molecular drag pump and assets like small, multi-parameter battery powered sensor suite MiniGas embedded with micro PC control system, and telemetry system were integrated in an aircraft to acquire 4D image of an ...

4. Sprayer - Wikipedia

   en.wikipedia.org/wiki/Sprayer

   Sprayers range in size from man-portable units (typically backpacks with spray guns) to trailed sprayers that are connected to a tractor, to self-propelled units similar to tractors with boom mounts of 4–30 feet (1.2–9.1 m) up to 60–151 feet (18–46 m) in length depending on engineering design for tractor and land size.

5. Liquid-propellant rocket - Wikipedia

   en.wikipedia.org/wiki/Liquid-propellant_rocket

   An electric motor, generally a brushless DC electric motor, drives the pumps. The electric motor is powered by a battery pack. It is relatively simple to implement and reduces the complexity of the turbomachinery design, but at the expense of the extra dry mass of the battery pack. Example engine is the Rutherford designed and used by Rocket Lab.

6. Hibar Systems - Wikipedia

   en.wikipedia.org/wiki/Hibar_Systems

   Hibar Systems Ltd was a Canadian manufacturer of automated, precision liquid dispensing and filling systems. Hibar was started in 1974 when German-born Canadian engineer Heinz Barall developed a prototype of a precision metering pump that would dispense a small, precise amount (two microlitres) of electrolytes into button cell batteries. Barall ...

7. Spray (liquid drop) - Wikipedia

   en.wikipedia.org/wiki/Spray_(liquid_drop)

   A spray is a dynamic collection of drops dispersed in a gas. [1] The process of forming a spray is known as atomization. A spray nozzle is the device used to generate a spray. The two main uses of sprays are to distribute material over a cross-section and to generate liquid surface area.
