<p>The present invention is a method of and an apparatus for creating a pulsed stream of particles in a carrier means, such as air. A pre-metered stream of particles is accumulated in a pulsing chamber (320) of a pulsing means (310) by interrupting the stream of particles by a separator means (330), which interrupts the flow for a certain portion of the pulse period. The accumulated particles are the removed from the pulsing means by suction, such as by using ejectors. <IMAGE></p> |
