COOPERATIVE PATENT CLASSIFICATION
G05D
SYSTEMS FOR CONTROLLING OR REGULATING NON-ELECTRIC VARIABLES [2023-01]
NOTES

  • This subclass does not cover features of general applicability to regulating systems, e.g. anti-hunting arrangements, which are covered by subclass G05B.
  • In this subclass, the following term is used with the meaning indicated:
    • "systems" includes self-contained devices such as speed governors, pressure regulators.
  • Control systems specially adapted for particular apparatus, machines or processes are classified in the subclasses for the apparatus, machines or processes, provided that there is specific provision for control or regulation relevant to the special adaptation, either at a detailed level, e.g. A21B 1/40: "for regulating temperature in bakers' ovens", or at a general level, e.g. B23K 9/095: "for automatic control of welding parameters in arc welding". Otherwise, classification is made in the most appropriate place in this subclass.
WARNING

  • In this subclass non-limiting references (in the sense of paragraph 39 of the Guide to the IPC) may still be displayed in the scheme.
