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.

 B09
DISPOSAL OF SOLID WASTE; RECLAMATION OF CONTAMINATED SOIL (treatment of waste water, sewage or sludge C02F; treating radioactively contaminated solids G21F 9/28)  [3,6]
 B09C
RECLAMATION OF CONTAMINATED SOIL (gatherers for removing stones or the like from the soil A01B 43/00; sterilising soil by steam A01G 11/00; separation in general B01D; cleaning beaches E01H 12/00; removing undesirable matter, e.g. rubbish, from the land E01H 15/00)  [6]
 B09C

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]
    are further classified in subclass C12S[6]
 B09C 1/00 - 
B09C 1/00

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]

 B09C 1/00
Reclamation of contaminated soil  [6]
 B09C 1/02
·  Extraction using liquids, e.g. washing, leaching  [6]
 B09C 1/04
·  Flotation  [6]
 B09C 1/06
·  thermally (incinerators for contaminated soil F23G 7/14)  [6]
 B09C 1/08
·  chemically (chemical means for combatting harmful chemical agents A62D 3/00)  [6]
 B09C 1/10
·  microbiologically or by using enzymes  [6]
 B09C 101/00
Indexing scheme associated with groups B09C 1/00-B09C 1/10, relating to the reclamation of contaminated soil. The indexing code should be unlinked.  [6]
 B09C 101/00 - 
B09C 101/00

Note(s)

Attention is drawn to Chapter IV of the Guide which sets forth the rules concerning the application and presentation of the different types of indexing code. [6]
