B24C

ABRASIVE OR RELATED BLASTING WITH PARTICULATE MATERIAL

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

the equivalent use of material without particles or pellets for deburring, removal of extended surface areas or jet milling of local recessions, e.g. grooves

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

In this subclass non-limiting references (in the sense of paragraph 39 of the Guide to the IPC) may still be displayed in the scheme.
