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 1 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". "Proportional band" means that range of values of deviation which corresponds to the full operating range of output signal of the controlling unit resulting from proportional action only.
