Full Title

Full titles differ between systems:

IPC:

Apparatus or methods for producing mixtures of cement with other substances, e.g. slurries, mortars, porous or fibrous compositions > using driven mechanical means affecting the mixing > Mixing in containers not actuated to effect the mixing > with stirrers sweeping through the materials

CPC:

Apparatus or methods for producing mixtures of cement with other substances, e.g. slurries, mortars, porous or fibrous compositions (controlling the mixing apparatus and supplying the ingredients B28C7/00 ) > using driven mechanical means affecting the mixing (B28C5/40, B28C5/42, B28C5/48 take precedence; in combination with the action of a fluid B28C5/38) > Mixing in containers not actuated to effect the mixing > with stirrers sweeping through the materials

CPC subdivides this area 3x more granularly than IPC with 4 additional codes.

4 codes are CPC-only extensions.
