without stationary working-fluid guiding means; (F01D1/24, F01D1/32, F01D1/34 take precedence; )

Introduced: September 1968

Title

Titles differ between systems:

IPC: without working-fluid guiding means

CPC: without stationary working-fluid guiding means; (F01D1/24, F01D1/32, F01D1/34 take precedence; )

Full Title

Full titles differ between systems:

IPC:

Non-positive-displacement machines or engines, e.g. steam turbines > without working-fluid guiding means

CPC:

Non-positive-displacement machines or engines, e.g. steam turbines (wit working-fluid flows in opposite axial directions for balancing axial thrust F01D3/02; with other than pure rotation F01D23/00; turbines characterised by their use in special steam systems, cycles, or processes, regulating devices therefor F01K) > without stationary working-fluid guiding means; (F01D1/24, F01D1/32, F01D1/34 take precedence; )

IPC and CPC are identically structured here. All 2 subcodes exist in both systems.
