摘要： A drop deflector apparatus for a continuous drop emission system that deposits a liquid pattern on a receiver according to liquid pattern data comprising a plurality of drop nozzles formed along a nozzle array axis and emitting a plurality of continuous streams of a liquid that breaks up into a plurality of streams of drops having nominal flight paths that are substantially parallel and substantially within a nominal flight plane is disclosed. An airflow plenum having an evacuation end connected to a negative pressure source and an impingement end having an opening located adjacent the nominal flight plane into which ambient air is drawn for the purpose of deflecting drops in an air deflection direction perpendicular to the nominal flight plane is provided. The opening is bounded by upstream, downstream, first and second walls wherein the upstream and downstream wall ends are spaced away from the nominal flight plane in the air deflection direction by a larger amount than are the first and second side wall edges. An airflow plenum having through slots for the passage of drops is also disclosed. Such a plenum design increases the amount of drop deflection achieved for a given maximum deflection air velocity and provides a reduction in the affect of perturbing air currents that may be present around the nominal flight paths. Drop synchronization apparatus is disclosed to break up continuous streams into drops of large and small volumes according to liquid pattern data, the large and small drops being differently deflected by the air flow in the airflow plenum. A plurality of path selection elements is disclosed for directing drops along different paths according to liquid pattern data, wherein drops following different paths are differently deflected by the air flow in the airflow plenum. A method of printing using the disclosed apparatus is also disclosed.

摘要： A continuous drop emitter comprising a liquid supply chamber containing a liquid held at a positive pressure; first and second nozzles in fluid communication with the liquid supply chamber nozzles emitting first and second continuous streams of a liquid; first and second stream break-up transducers adapted to independently synchronize the break up of the first and second continuous streams of the liquid into first and second streams of drops of predetermined volumes, respectively; and an acoustic damping material located adjacent to or within the liquid supply chamber for damping sound waves generated within the liquid chamber by the first and second stream break-up transducer. The continuous drop emitter may also configured with a Helmholtz resonant chamber tuned to a critical stimulation frequency having an acoustic damping material therein for absorbing acoustic stimulation energy. The Helmholtz resonant chamber may serve as a portion of the common liquid supply for the first and second jets in which case the acoustic damping material may be porous to allow the liquid to pass through. The acoustic damping materials may acoustically lossy materials that transmute energy into heat via molecular motions. The acoustic damping materials may be porous materials that absorb acoustic energy by forcing the liquid through small passages causing viscous flow energy losses. In addition the acoustic damping materials may include components that cause the disruption of acoustic waves by reflection from materials that are impedance mismatched to the liquid, either very dense materials or gas filled voids.
