Notes |
|
(1) | Electrolytic or electrophoretic processes or apparatus or operational features are classified |
|
(i) | in the groups for the compounds or articles produced, and |
|
(ii) | in the groups which cover the apparatus or operational features. [2] |
|
(2) | The electrolytic or electrophoretic purification of materials is classified according to the nature of the liquid in the relevant places, e.g. A 01 K 63/00, C 02 F 1/46, C 25 B 15/08, C 25 D 21/16, C 25 F 7/02. [2] |
