Introduced: January 1980
Title
Titles differ between systems:
IPC: Control of fuel supply
CPC: Control of fuel supply (F02C9/48 takes precedence; fuel valves F02C7/232)
Full Title
Full titles differ between systems:
Controlling gas-turbine plants; Controlling fuel supply in air-breathing jet-propulsion plants > Control of fuel supply
Controlling gas-turbine plants; Controlling fuel supply in air- breathing jet-propulsion plants (controlling air intakes F02C7/057; controlling turbines F01D; controlling compressors F04D27/00; controlling in general G05) > Control of fuel supply (F02C9/48 takes precedence; fuel valves F02C7/232)
Of 11 combined children, 9 exist in both systems.
2 codes are CPC-only extensions.
3 shared codes have differing titles between IPC and CPC.
IPC defines codes here since 1980.
