| B 24 C | ABRASIVE OR RELATED BLASTING WITH PARTICULATE MATERIAL |
|
| Notes |
|
| (1) | 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. |
|
| (2) | 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. |
