Closeup of the undercutting bar and results on a Plasser & Theurer ballast cleaner in use in Hungary in 2009. A cutter bar runs beneath sleeper level excavating all of the ballast under the sleepers to a specified, variable depth. A conveyor then moves the ballast into the cleaner, where it gets forced through a mesh by a shaking chamber. [4]

Ultrasonic cleaning is a process that uses ultrasound (usually from 20 to 40 kHz) to agitate a fluid, with a cleaning effect. Ultrasonic cleaners come in a variety of sizes, from small desktop units with an internal volume of less than 0.5 litres (0.13 US gal), to large industrial units with volumes approaching 1,000 litres (260 US gal).
Pickling is a metal surface treatment used to remove impurities, such as stains, inorganic contaminants, and rust or scale from ferrous metals, copper, precious metals and aluminium alloys. [1]
Fused quartz, fused silica or quartz glass is a glass consisting of almost pure silica (silicon dioxide, SiO 2) in amorphous (non-crystalline) form.
The electrical resistance of the coil, the voltage output of the device, the airflow of the atomizer and the efficiency of the wick all affect the vapor coming from the atomizer. [83] They also affect the vapor quantity or volume yielded. [83] Atomizer coils made of kanthal usually have resistances that vary from 0.4Ω to 2.8Ω. [83]
The Lavet-type stepping motors used in analog quartz clock movements which themselves are driven by a magnetic field (generated by the coil) can be affected by external (nearby) magnetism sources, and this may impact the rotor sprocket output. As a result, the mechanical output of analog quartz clock movements may temporarily stop, advance or ...
The solution should be allowed to cool, and oxygen gas should be allowed to dissipate prior to disposal. When cleaning glassware, it is both prudent and practical to allow the piranha solution to react overnight taking care to leave the receptacles open under a ventilated fume cupboard. This allows the spent solution to degrade prior to ...
