The contacts should last for a year with constant use, while thesprings may never need renewing. In short we recommend the Roentgen Self-Starting Mechani-cal Interrupter as the most efficient, most reliable, and most satis-factory of the various mechanical interrupters which are offeredto-day. 20 James G. Biddle, 1114 Chestnut Street, Philadelphia. Interrupter and Condenser. Figure 10. Roentgen Self-Starting Mechanical Inter-rupter and Adjustable Condenser,witn Switches. A COMPLETE interrupter with adjustable condenser and switchesas shown can readily be adapted to coils whose operations isrendered unsatisfaclory because of the inefficiency of the output of an induction coil, operated by the ordinary mechani-cal interrupter, can be materially increased if the Roentgen Mechani-cal Interrupter be used in its place.
