Notes |
|
(1) | This class covers methods, systems, and apparatus for controlling, in general. |
|
(2) | In this class, the following terms or expressions 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; |
|
– | "automatic control" is often used in the art as a synonym for "regulation". |
|
(3) | Attention is drawn to the Notes following the title of section G, especially as regards the definition of the term "variable". |
