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

|  | G05 |
Note(s) Attention is drawn to the notes (particularly the definition of the term "variable") on page G 3 of this elaboration. This class covers methods, systems, and apparatus for controlling in general. In this class, the following terms are used with the meanings indicated: "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. "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".
