CONTROLLING; REGULATING (specially adapted to a particular field of use, see the relevant sub-class, e.g. B23Q)
 G05

Note(s)

  1. Attention is drawn to the notes (particularly the definition of the term "variable") on page 7 of this Section.
  2. This class covers methods, systems, and apparatus for controlling in general.
  3. In this class, the following terms are used with the meanings indicated:
    1. "Controlling" means influencing a variable in any way, e.g. changing its direction or its value (including changing it to or from zero), maintaining it constant, limiting its range of variation.
    2. "Regulation" means maintaining a variable automatically at a desired value or within a desired range of values. The desired value or range may be fixed, or manually varied, or may vary with time according to a predetermined "programme" or according to variation of another variable. Regulation is a form of control; the term "automatic control" is often used in the art as a synonym for "regulation".
