G01D 5/26 characterised by optical transfer means, i.e. using infrared, visible, or ultraviolet light
Introduced: September 1968
Title
Titles differ between systems:
IPC: using optical means, i.e. using infrared, visible or ultraviolet light
CPC: characterised by optical transfer means, i.e. using infrared, visible, or ultraviolet light
Full Title
Full titles differ between systems:
Mechanical means for transferring the output of a sensing member; Means for converting the output of a sensing member to another variable where the form or nature of the sensing member does not constrain the means for converting; Transducers not specially adapted for a specific variable > using optical means, i.e. using infrared, visible or ultraviolet light
Mechanical means for transferring the output of a sensing member; Means for converting the output of a sensing member to another variable where the form or nature of the sensing member does not constrain the means for converting; Transducers not specially adapted for a specific variable (G01D3/00 takes precedence; specially adapted for apparatus giving results other than momentary value of variable G01D1/00) > characterised by optical transfer means, i.e. using infrared, visible, or ultraviolet light
Of 8 combined children, 4 exist in both systems.
4 codes are CPC-only extensions.
3 shared codes have differing titles between IPC and CPC.
