CPC Definition - Subclass G06G
This place covers:
Hand operated, mainly portable, mechanical devices using movable scales (linear or circular) for computing an analogue outcome as a result of the mechanical setting of the input scales.
These are very simple mechanical devices for solving specific problems involving the resolving of one or a limited number of mathematical equations by moving mechanically one scale relative to another scale and reading out the result on another scale. It does not involve electricity nor electronics.
This place does not cover:
Planimeters | |
Digital mechanical computers | |
Electronic portable computers |
The documents should be classified in the subgroups of G06G 1/0005 according to their field of application AND in the subgroups of G06G 1/02 according to their construction.
This place covers:
For the different applications see the titles of the subgroups.
Documents should be classified in every subgroup dealing with a specific application where the hand manipulated analogue computing device is used.
Documents should also be classified in the subgroups of G06G 1/02 according to their construction.
This place covers:
Hand-manipulated devices of the kind specified in the title are classified here independently from the specific application.
The different constructional arrangements of these devices are classified in accordance with the titles of the subgroups under G06G 1/04.
The documents should also be classified in the subgroups of G06G 1/0005 according to their field of application.
This place covers:
Pure mechanical analogue computation mechanisms.
This place does not cover:
Obsolete technology, there are currently almost no new publications on the subject.
This place covers:
Analogue computation mechanisms based on fluid-pressure elements, e.g. using water, oil, pneumatics.
This place does not cover:
Obsolete technology, not used anymore.
This place covers:
General analogue computation performed by electric or magnetic elements.
This place does not cover:
Analogue control systems | |
Analogue filters or mixers |
Documents are to be classified in these subgroups only if they are used for pure computation per se.
Analogue computation for a specific application are classified in the specific application field only.
This is an old technology that is hardly used anymore for performing computation as such. It is mainly used as a component in larger systems such as analogue control systems, telecommunication devices, etc.
