  • Patent number: 5963758
    Abstract: A system for substantially maintaining color density in liquid toners for electrographic printers is disclosed. The system includes means for substantially continuously supplying toner concentrate to a printer and means for substantially continuously withdrawing liquid toner from a printer into a waste flowstream. A method to achieve substantially consistent color density of liquid toner in an electrographic printing system is also disclosed.
    Type: Grant

  • Patent number: 4109863
    Abstract: An improved apparatus for ultrasonic nebulization of liquid samples or suspensions in which the piezoelectric transducer is protected from chemical attack and erosion. The transducer is protected by being bonded to the inner surface of a glass plate which forms one end wall of a first hollow body provided with apparatus for circulating a fluid for cooling and stabilizing the transducer. The glass plate, which is one-half wavelength in thickness to provide an acoustically coupled outer nebulizing surface, seals an opening in a second hollow body which encloses an aerosol mixing chamber. The second body includes apparatus for delivering the sample solution to the nebulizing surface, a gas inlet for providing a flow of carrier gas for transporting the aerosol of the nebulized sample and an aerosol outlet.
