Note(s)

Inventions relating to cleaning are usually classified according to one (or more) of the undermentioned aspects, and are only classified in this class if they are not fully classifiable in a class providing for such an aspect:

  1. the article cleaned, e.g. filters B01D, castings and moulds B22D 29/00, vehicles B60S, coke ovens C10B 43/00, building forms E04G, boilers F22, combustion apparatus F23, furnaces F27;
  2. the general nature of the cleaning, e.g. preparing for sugar manufacture A23N, domestic cleaning A47L, treatment of textiles D06, laundry D06F, air-conditioning F24F;
  3. the particular operation performed, e.g. filtering B01D, separating of solids B03, B07, sand-blasting B24C;
  4. the particular apparatus or device per se, e.g. brushes A46B, mops A47L, centrifuges B04, hand tools B25;
  5. the substance cleaned, e.g. metals B21C, C23, water C02, glass C03B, leather C14B, textile fibres D01;
  6. the substance removed (or prevented from depositing or forming), e.g. implements or apparatus for removing dry paint from surfaces B44D 3/16, chemical paint-removers C09D 9/00, preventing rust C23F;
  7. the substance used, e.g. macromolecular compounds or compositions C08, anti-icing compositions C09K, detergents C11D;
  8. the operation in connection with which cleaning is done, e.g. metal rolling B21B, metal boring B23B, soldering B23K, textile fabrication D01G, D01H, D03J, D04B;
    1. the surroundings of a surface to be cleaned or kept clean, e.g. water in a boiler C02F, air in a room F24F.
