Requirements governing the representation of your invention in the drawings are set out in Rules 32, 34 and 35. Reference signs not mentioned in the description and claims must not be used in the drawings, and vice versa. The same features, when denoted by reference signs, must be denoted by the same signs throughout the application.

95

Drawings must not contain text matter except, when absolutely indispensable, brief terms such as "water", "steam", "open", "closed", "section on AB" and, on electric circuits and block schematics or flow sheet diagrams, short catchwords indispensable for understanding. Any such words must be placed in such a way that they can be replaced by their translations without interfering with any lines of the drawings.

Flow sheets and diagrams are considered to be drawings.
