SYSTEMS FOR CONTROLLING OR REGULATING NON-ELECTRIC VARIABLES( for continuous casting of metals B22D 11/16 ; valves per se F16K; sensing non-electric variables, see the relevant subclasses of G01; for regulating electric or magnetic variables G05F )
NOTE
-
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 madein the most appropriate place in this subclass. The following are lists of places where there is specific provision of the kind referred to above. Where such provision is at a detailed level, the places have been grouped according to the main groups of this subclass. Where the provision is at a general level (e.g. of a kind appropriate to more than one of the main groups specified in the lists, or to main groups G05D 27/00 or G05D 29/00 ), the places are listed under the title "General References".

NOTE
-
This group covers control of position or course in two dimensions specially adapted for land vehicles, i.e. control systems to define a trajectory for a land vehicle, and to take suitable actions to make the vehicle follow said trajectory.
Relationships with other classification places.
Subclass G01C covers navigation in general, i.e. determining the position and course of land vehicles, ships, aircraft, and space vehicles.
Subclass G01S covers radio, sonar or lidar navigation systems, i.e. navigation by use of radio, acoustic or optical waves, or analogue arrangements using other electromagnetic waves.
Subclass G08G covers navigation systems for traffic control purposes, i.e. systems in which the navigation is not performed autonomously by or in the vehicle, but where the vehicles are guided by instructions transmitted to them.
Aspects of navigation systems that are important per se should also be classified in the relevant groups of G01C (see for example list under "Informative References" below).
Aspects of radio, sonar or lidar navigation systems that are important per se should also be classified in the relevant groups of G01S (see for example list under "Informative References" below).
Aspects of navigation systems for traffic purposes that are important per se should also be classified in the relevant groups of G08G (see for example list under "Informative References" below).
