Full Title

Full titles differ between systems:

IPC:

Plural gas-turbine plants; Combinations of gas-turbine plants with other apparatus; Adaptations of gas-turbine plants for special use > Gas-turbine plants providing heated or pressurised working fluid for other apparatus, e.g. without mechanical power output > supplying working fluid to a user, e.g. a chemical process, which returns working fluid to a turbine of the plant > Turbochargers, i.e. plants for augmenting mechanical power output of internal-combustion piston engines by increase of charge pressure

CPC:

Plural gas-turbine plants; Combinations of gas-turbine plants with other apparatus; Adaptations of gas-turbine plants for special use > Gas-turbine plants providing heated or pressurised working fluid for other apparatus, e.g. without mechanical power output (F02C6/18 takes precedence ) > supplying working fluid to a user, e.g. a chemical process, which returns working fluid to a turbine of the plant > Turbochargers, i.e. plants for augmenting mechanical power output of internal-combustion piston engines by increase of charge pressure
