SECTION B — PERFORMING OPERATIONS

SEPARATING AND MIXING

|  | B07 |
SEPARATING SOLIDS FROM SOLIDS; SORTING (separation in general Fulltext... Hierarchy... Expanded...B01D; wet separating processes, sorting by processes using fluent material in the same way as liquid Fulltext... Hierarchy... Expanded...B03; using liquids Fulltext... Hierarchy... Expanded...B03B, Fulltext... Hierarchy... Expanded...B03D; sorting by magnetic or electrostatic separation Fulltext... Hierarchy... Expanded...B03C; centrifuges or vortex apparatus for carrying out physical processes Fulltext... Hierarchy... Expanded...B04; sorting peculiar to particular materials or articles and provided for in other classes, see the relevant classes)

|  | B07B |
SEPARATING SOLIDS FROM SOLIDS BY SIEVING, SCREENING, OR SIFTING OR BY USING GAS CURRENTS; OTHER SEPARATING BY DRY METHODS APPLICABLE TO BULK MATERIAL, e.g. LOOSE ARTICLES FIT TO BE HANDLED LIKE BULK MATERIAL (combinations of dry separating apparatus with wet separating apparatus Fulltext... Hierarchy... Expanded...B03B; hand sorting, postal sorting, sorting by switching or other devices actuated in response to detection or measurement of some feature of articles or samples of material Fulltext... Hierarchy... Expanded...B07C)

|  | B07B |
Note(s) In this sub-class, any sorting or grading of bulk material or loose articles fit to be handled like bulk material results automatically from the construction of the apparatus and properties of the material, e.g. by a trap opening under an object of a certain minimum weight, by an aperture of graduated size. Sorting of articles is included in so far as the same conditions apply, e.g. sorting of timber by passing it over successively longer openings; the articles may or may not be orientated for the purpose of sorting.

|  | B07C |
POSTAL SORTING; SORTING INDIVIDUAL ARTICLES, OR BULK MATERIAL FIT TO BE SORTED PIECE-MEAL, e.g. BY PICKING (specially adapted for a specific purpose covered by another class, see the relevant class, e.g. Fulltext... Hierarchy... Expanded...A43D 33/06, Fulltext... Hierarchy... Expanded...B23Q 7/12)

|  | B07C |
Note(s) This sub-class covers sorting of materials or articles by hand or by devices actuated, manually or automatically, as a result of inspection or of detection or measurement of some feature of the material or articles.
