Figure 8. Roentgen Electrolytic Interrupter. THE special work of the Electrolytic Interrupter is that of shortexposures in radiography.The ordinary mechanical interrupter has not a sufficient currentcarrying capacity to permit of its use when the very heavy dischargesare demanded of an induction coil for short exposures in radiographicwork. La sre C V ^^^ Electrolytic Interrupter has, however, a large current carrying capacity, and is especially suitablefor producing the heavy discharges necessary for quick exposures.It can be made to deliver momentarily from two to thirty amperes ofcurrent to a properly designed induction coil for the purpose of mak-ing a snap shot exposure, or it can be readily adjusted to furnish lesscurrent as desired. It is thus readily understood that the use of theElectrolytic Interrupter on large induction coils is the thing whichhas made possible the short exposure skiagraphic work. James G.
