SO that at intervals a discharge of that condenser is discs are, however, so set on the shaft that they do notproduce these discharges simultaneously but successively. Eachseparate inductance is inductively coupled to the antennacircuit as shown in the diagram, so that the damped oscillationsin each condenser circuit produce inductively secondary oscil-lations in the antenna circuit which overlap in step with eachother as shown in the diajrram in Fig. 24. The result is to produce in the antenna or secondary circuitoscillations which are practically continuous. Lastly, we may notice a recent extension of the arc method ofproducing undamped oscillations. There are a certain numberof materials, mostly crystalline substances, whicli have theproperty that the light contact between them has a unilateral 112 RA DIO TELEGRA PIl Y conductivity or conducts electricity better in one direction thanth
