current in the induction coil and should never be operated without first opening the Operating Switch. Next to the Pole Changing Switch, is the Condenser Switch, by means of which the amount of condenser shunted across the heavy contacts of the interrupter may be varied and the best conditions secured for the particular value of current which is being used. T he illustration shows the interrupter andThe Regular Type. , ... ... .. , condenser with auxiliary parts as supplied for use with our regular type A coils. When it is furnished to be adapted to other coils, it is provided with two pairs of binding posts, instead of one as shown, and these are plainly stamped 11 Line for connection to the source of current and Coil for connection to the induction coil primary.

Figure ix. Roentgen Electrolytic Interrupter.Type A. 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 dis-charges are demanded of an induction coil for short exposures inradiographic work. The electrolytic interrupter has, however,Large apac y. a jarge current carrying capacity, and is especially suitable for producing the heavy discharges necessaryfor quick exposures. It can be made to deliver momentarily fromtwo to thirty amperes of current to a properly designed inductioncoil for the purpose of making a snap shot exposure, or it can bereadily adjusted to furnish less current as desired. It is thus readilyunderstood that the use of the electrolytic interrupter on large in-duction coils is the thing which has made possible the short exposure skiagraphic work. It consists essentially of a small anode ofDescription. iridio-p
