Abstract
A scanning apparatus is provided for scanning a stream of atomized particles comprising a pneumatic valve through which gas can be routed to one or more nozzles to give a scanning action on the stream of atomized particles which routing is externally adjustable and externally programmable.
Claims6
Apparatus for scanning, in a predetermined manner, a stream of atomized particles directed along an axis, said apparatus comprising:
- a) at least one gas nozzle arranged to direct a scanning gas toward the axis;
- and
- b) a rotatable pneumatic valve having a rotor and a routing means arranged to route an amount of said scanning gas through said valve to said at least one gas nozzle to thereby impart a scanning action to the stream of atomized particles,
- wherein said amount of scanning gas routed through said valve to said at least one nozzle is arranged to vary cyclically in a pre-determined manner with rotation of said rotor, said routing means being externally adjustable and externally programmable to be displaced between a first routing configuration and a second routing configuration in order to alter said pre-determined cyclical variation of gas routed through said valve.
