Note(s)

The following notes are meant to assist in the use of this part of the classification scheme; they must not be read as modifying in any way the elaborations.

  1. In this sub-section, the separation of different materials, e.g. of different matter, size, or state, is predominantly found in the following subclasses:

    B01D

    B03B, B03C, B03D

    B04B, B04C

    B07B, B07C.

  2. The classifying characteristics of these subclasses are:
    1. the physical state of the matter to be separated;
    2. the principle of the process used;
    3. particular kinds of apparatus.
    The first of these characteristics involves six different aspects, assembled in three groups:
    1. liquid/liquid or liquid/gas and gas/gas;
    2. solid/liquid or solid/gas;
    3. solid/solid.
  3. These subclasses are to be used according to the following general rules:
    It should also be noted that the separation of isotopes of the same chemical element is covered by B01D 59/00, whatever process or apparatus is employed.
  4. The following scheme illustrates the classification according to these rules.

Note(s)

  1. In this subclass, the following term is used with the meaning indicated:  [6]
    • "reclamation" means the partial or total elimination or the fixing of contaminants in soil.  [6]
  2. Processes using enzymes or micro-organisms in order to:  [6]
    1. liberate, separate or purify a pre-existing compound or composition, or to  [6]
    2. treat textiles or clean solid surfaces of materials  [6]

Note(s)

In groups B09C 1/00-B09C 1/10, it is desirable to add the indexing code of group B09C 101/00. The indexing code should be unlinked.  [6]
