G03
Note(s)
In this class, the following terms are used with the meaning indicated:
"records" means photographs or any other kind of latent, directly-visible or permanent storage of pictorial information, which consist of an imagewise distribution of a quantity, e.g. an electric charge pattern, recorded on a carrier member;
"optical" applies not only to visible light but also to ultra-violet or infra-red radiations.

G05
Note(s)
This class covers methods, systems, and apparatus for controlling, in general.
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".
Attention is drawn to the Notes following the title of section G, especially as regards the definition of the term "variable".
simulators which are concerned with the mathematics of computing the existing or anticipated conditions within the real device or system;
simulators which demonstrate, by means involving computing, the function of apparatus or of a system, if no provision exists elsewhere.
This class does not cover:
control functions derived from simulators, in general, which are covered by class Fulltext... Hierarchy... Expanded...G05, although such functions may be covered by the subclass of this class for the device controlled;
simulators regarded as teaching or training devices which is the case if they give perceptible sensations having a likeness to the sensations a student would experience in reality in response to actions taken by him. Such simulators are covered by class Fulltext... Hierarchy... Expanded...G09;
components of simulators, if identifical with real devices or machines, which are covered by the relevant subclass for these devices or machines (and not by class Fulltext... Hierarchy... Expanded...G09).
In this class, the following terms or expressions are used with the meanings indicated:
'calculating" or "computing" includes, inter alia, operations on numerical values and on data expressed in numerical form. Of these terms "computing" is used throughout the class;
"computation" is derived from this interpretation of "computing". In the French language the term "calcul" will serve for either term;
"simulator" is a device which may use the same time scale as the real device or operate on an expanded or compressed time scale. In interpreting this term models of real devices to reduced or expanded scales are not regarded as simulators;
"record carrier" means a body, such as a cylinder, disc, card, tape, or wire, capable of permanently holding information, which can be read-off by a sensing element movable relative to the recorded information.
Attention is drawn to the Notes following the title of section G, especially as regards the definition of the term "variable".
This class covers all sound-emitting devices, in general, whether or not they may be considered as being musical.
In this class, the following expression is used with the meaning indicated:
"musical instrument" does not exclude devices emitting a single sound signal.
The following Class Index is given in place of subclass indexes, to show the grouping of the elaborations belonging to different subclasses, under the following three fundamental types:
wind instruments;
string instruments;
percussion instruments,
which relate clearly to the majority of instruments.
