FIGURE 26. Roentgen Static Transformer. THE Roents:en Static Transformer is used to obtain Static Dis-chm^ges from the ordinary induction coil. The discharge from aninduction coil is too heavy, even when the coil is operated as lightlyas possible, to be used directly in electro-therapeutic applications.Because of this fact the static machine, the discharge from which isvery light and especially suited to this work, till now has been theonly machine available for the purpose. Resonance Many attempts have been made to utilize the in- Apparatus. duction coil in electro-therapeutics by using a smallTesla coil, or some form of resonance apparatus, with it. All thesede\ices give a discharge of high potential and sufficiently light involume, but alternating and not unidirectional as is needed for thebest results. The discharge from the Roentgen Static Transformer is practicallyunidirectional. Its Discharge It is as much so as the discharge of the induction VnidirectionaL coil by which it is
