Claims Analysis
Total Claims: 18
Claim 1
Independent Claim
79 words
A method of generating a vapor stream comprising the steps of providing a jet of electrostatically chargeable particles; controlling the jet by electrostatic deflection so that some of the particles of the jet are directed into a vaporizer for a period of time sufficient to become vaporized while other particles of the jet are not directed into the vaporizer for a period of time sufficient to become vaporized; and emitting the vaporized particles from the vaporizer as a stream.
Claim 2
Independent Claim
79 words
A method of generating a vapor stream comprising the steps of providing a jet of electrostatically chargeable particles; controlling the jet by electrostatic deflection so that some of the particles of the jet are directed into a vaporizer for a period of time sufficient to become vaporized while other particles of the jet are not directed into the vaporizer for a period of time sufficient to become vaporized; and emitting the vaporized particles from the vaporizer as a stream.
Claim 3
Dependent Claim
35 words
A method of generating a vapor stream in accordance with claim 1 wherein a carrier gas having a liquefaction temperature substantially lower than the boiling temperature of the liquid particles is passed through the vaporizer.
Claim 4
Dependent Claim
24 words
A method of generating a vapor stream in accordance with claim 1 wherein the liquid particles have a viscosity of less than 100 cps.
Claim 5
Independent Claim
74 words
