A break so constructed we know from experience to work  very satisfactorily, and it can be renewed many times for the  cost of one of the more elaborate breaks put on the market,  which will give little, if any. better results.

With electrolytic breaks the frequency of interruption will  vary according to the pressure of current supplied, higher  voltages producing more rapid interruption. By exposing a  larger area of the platinum anode to the fluid the rate of  interruption is reduced, and by exposing less the rate is  accelerated. The increased area of exposure allows a higher  amperage to pass. With the electrodes suspended from  separate strips of wood, glass, or other insulating material,  as shown in Fig. 36, some regulation of the action may be  secured by moving the two electrodes to various distances  apart.

For working with this form of break, an induction-coil with  short primary winding should be employed, since the self-  induction of longer primaries prevents the full effect of the  break’s special efficiency reaching the X-ray tube.  The condenser of the coil should in all cases with these  breaks be put out of circuit.
