Page "Corona treatment" Paragraph 3

Verner found that there were already a couple of ways to accomplish this.

One was a gas flame method and the other was a spark generating method, both of which were crude and uncontrollable and did not produce a homogeneous product.

Verner came up with the theory that a high frequency corona discharge would provide both a more efficient and controllable method to treat the surface.

Exhaustive experiments proved him to be correct.

Verners company, Vetaphone, obtained patent rights for the new corona treatment system.
