  • Patent number: 6874712
    Abstract: A powder spraying gun generates a desired pattern of electrostatically charged particles for coating a workpiece without rotating parts or particle deflectors. The powder pattern is generated with a funnel-shaped output in conjunction with air introduced into a powder charging chamber of the gun in a tangential swirling motion. The swirling air is additionally used to purge agglomerated powder particles from the charging electrodes in the charging chamber. The charging chamber surface is fashioned from material exhibiting low friction or high resistance to powder impact fusion.

  • Patent number: 6857580
    Abstract: A piezoelectrically actuated liquid atomizer device which applies alternating voltages from an ordinary wall outlet to a piezoelectric actuator intermittently and at a high rate sufficient to cause an atomization plate which is vibrated by the actuator to form small droplets from liquid which is supplied to the plate. The intermittent application of voltages to the piezoelectric actuator is carried out according to a duty cycle in which the off times are adjustable. An override of the duty cycle is provided so that the piezoelectric actuator operates continuously for intervals which are manually or automatically controlled.
