Knudsen Vacuum Gage : It is a device used for measuring
negative gas pressures. In this device a rotatable vane is moved
by the pressure of heated molecules, proportionately to the
concentration of molecules in the system. |
Knurl : To provide a surface with small ridge or knobs
to ensure a firm grip to a metal. |
Knurling : It is a manufacturing process, typically conducted

a better grip on the knurled object than would be provided by
the originally-smooth metal surface. |
Konimeter : It is a device which is used to measure dust
in mine atmosphere. A measured volume of air is drawn through
a jet impacts on a glass surface coated with glycerin jelly.
The adherent dust is then examined and the particles are counted
under the microscope. Also known as Zeiss konimeter. |
