<p>Method and apparatus for controlling dispensing of ''dry'' powdered compositions particularly carpet cleaning compositions wherein the confined finely divided particles descend in a stream under gravity and have oscillatory movement imparted thereto next before discharge through an orifice leading therefrom so as to agitate, separate and propel the particles therethrough and in the case of carpet cleaning operations depositing the finely divided discharged particles onto the surface of the fibres in a substantially uniform pattern thereover followed by working same into the fibres through the application thereto of a rotary brush or beater (78) and thereafter recovering the residues by a suitable suction or vacuum unit utilizing a rotary brush or beater (78) and an associated two stage cyclone separator (14).</p> |
