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.

 B06
GENERATING OR TRANSMITTING MECHANICAL VIBRATIONS IN GENERAL
 B06B
GENERATING OR TRANSMITTING MECHANICAL VIBRATIONS IN GENERAL (for particular physical or chemical processes, see the relevant subclasses, e.g. B07B 1/40, B22C 19/06, B23Q 17/12, B24B 31/06, E01C 19/22; measurement of mechanical vibrations, including the combination of generation and measurement, G01H; systems using reflection or reradiation of acoustic waves G01S 15/00; generating seismic energy for prospecting G01V 1/02; control of mechanical vibrations G05D 19/00; methods or devices for transmitting, conducting or directing sound, in general G10K 11/00; synthesis of acoustic waves G10K 15/02; piezo-electric, electrostrictive or magnetostrictive elements H01L 41/00; motors with vibrating magnet, armature or coil H02K 33/00; motors using piezo-electric effect, electrostriction or magnetostriction H02N 2/00; generation of electrical oscillations H03B; electromechanical resonators as resonant circuit elements H03H; loudspeakers, microphones, gramophone pick-ups or like acoustic electromechanical transducers H04R)  [2]
 B06B

Note(s)

  1. This subclass covers arrangements for generating mechanical vibrations in solids, e.g. for the purpose of performing mechanical work. [6]
  2. This subclass does not cover arrangements for generating mechanical vibrations in fluids, which are covered by subclass G10K[6]
