Particulate source, circulation, and valving system for ballistic aerosol marking

摘要

A ballistic aerosol marking device includes, marking material which flows from a material reservoir to a delivery channel via a port. Flow of marking material is facilitated by the creation of a fluidized bed or aerosol of marking material in the reservoir. Gas flow together with mechanical or electromechanical assistance can be used to assist in the generation of the fluidized bed or aerosol.
