ormer which is used in thecustomary manner for working with the rectifier is also used for the photo-graphs on the single-impulse method. As compared ^^ith induction coilswith open magnetic circuit, the transformer with its closed iron core possessesa much higher efficiency. This is of particular advantage in connection withthe single-impulse method, as the current taken from the power mains maybe kept within the prescribed limits, a matter of considerable importance. In this connection the further advantage may be pointed out that theequipment can be connected directly to 400-volt power circuits ; this voltage APPARATUS FOR SINGLE-IMPULSE AND RAPID RADIOGRAPHY 7 is now frequently adopted, but is unsuitable for induction coils, and a reduc-tion in the voltage, which is in most cases not feasible, would be necessaryfor satisfactory operation. A description of the single-impulse system is as follows : Using theapparatus as a rectifier the continuous current is converted into alternating

The alternating current from the transformer is led through the rectifierdriven by the rotary converter, the high-tension alternating current beingthus converted into high-tension continuous current. This high-voltagecontinuous current is measured by a milliamperemeter and then led throughthe X-ray tube. The current in the tube is adjusted by resistances which are so pr^
