Introduced: September 1968

Title

Titles differ between systems:

IPC: Measuring linear or angular speed; Measuring differences of linear or angular speeds

CPC: Measuring linear or angular speed; Measuring differences of linear or angular speeds (G01P5/00 - G01P11/00 take precedence; ; counting mechanisms G06M)

Full Title

Full titles differ between systems:

IPC:

Measuring linear or angular speed; Measuring differences of linear or angular speeds

CPC:

Measuring linear or angular speed; Measuring differences of linear or angular speeds (G01P5/00 - G01P11/00 take precedence; ; counting mechanisms G06M)

IPC and CPC are identically structured here. All 6 subcodes exist in both systems.

3 shared codes have differing titles between IPC and CPC.
