1. A system for solidifying ink printed on a moving web of paper comprising:
a structure means for directing an airflow across a plurality of elongated and perforated hollow tubes at a high negative electrical potential,
said tubes also containing flammable gas under pressure, so disposed as to emit flames along the length of said tubes,
said tubes thereby becoming sufficiently heated so as to initiate thermionic-emission of ions from said tubes into said airstream, and
charge bars so disposed that said web is interposed between said charge bars and said tubes,
the ionized airstream being thereby attracted to the web interposed in the electrostatic field created between said tubes and said charge-bars, thereby causing ionization of gasses, vapors and fumes as they are emitted from said web, and
means for collecting said ionized gasses, fumes and vapors.
2. The system in claim 1 wherein the voltage on the charge tubes is sufficient to cause a corona on the surface of the web, the ultraviolet energy causing the inks and coatings to become solidified.
3. The system in claim 1 wherein the voltage on the charge tubes is sufficient to create an ozone atmosphere at the surface of the web, thereby causing the inks and coatings to become solidified.
4. A system for solidifying ink printed on a moving web of paper comprising:
a structure means for directing an airflow across a plurality of elongated tubes,
said elongated tubes being maintained at a sufficiently high temperature and electrical positive voltage potential to cause a stream of ions to be released from said tubes and said flames, thereby ionizing said airstream wherein
said elongated tubes contain a mixture of fuel and air and being so disposed as to support flames along their length, and
said flames being spaced from the web being treated , and
charge bars so disposed that said web is interposed between said charge bars and said elongated tubes, whereby an electrostatic field is created causing ionization of said vapors gasses and fumes as they are repelled from said web.
5. A system for solidifying a coating on a moving web comprising: blower and duct structures for directing an airflow across a plurality of heated high-voltage structures so disposed as to provide thermionic emission, the heated and ionized airflow then being attracted towards a plurality of elongated charge bars,
said moving web being interposed between said heated high-voltage structures and said charge bars and
said ionized airstream being thereby attracted to the web interposed in the electrostatic field created between said wires and said charge-bars,
thereby causing ionization of the emitted effluent consisting of condensing vapors, fumes and nascent gasses as they leave said web,
said web then moving into a second position wherein said emitted effluent is repelled from the web by a second charge bar and attracted to a collection structure.
6. The system in claim 5 wherein said coating is ink on the surface of a moving web of paper.
7. The system in claim 5 wherein said heated high-voltage structures are perforated hollow tubes containing flammable gas under pressure.
