GRINDING; POLISHING

|  | B24 |
Note(s) In this class, the following term is used with the meaning indicated: "grinding" is used in its most general sense to mean machining and covers, in particular, "corrective" operations.

|  | B24C |
ABRASIVE OR RELATED BLASTING WITH PARTICULATE MATERIAL

|  | B24C |
Note(s) This subclass covers: the use of a blast of any particles or pellets dispersed in air, gas, or liquid for the treatment of surfaces or cutting of materials, the particles usually being of abrasive material; the equivalent use of a jet of particles or pellets projected or energised by means other than a stream of air. In this subclass, the following terms are used with the meanings indicated: "abrasive" covers any material used in the manner mentioned in Note (1) above; "blast" covers any equivalent jet of material mentioned in Note (1) above.
