Wehnelt Break. — An interruptor of a type entirely diffe- rent from the preceding is Wehnelt's electrolytic break, one form of which is shewn in Fig. 63. The cathode is a sheet of lead /, the anode a platinum wire k, which protrudes slightly from the lower extremity of a little glass tube that surrounds it, the electrolyte being dilute sulphuric acid.
These two electrodes are inserted in circuit of the primary of the coil and a battery of at least 20 accumulators, as it is necessary for its... proper working that a fairly strong current should be used.
Digitized by LiOOQ IC RADIO-TELEGRAPHIC APPARATUS ii5 At the moment that the circuit is closed the platinum wire, if the current be sufficiently powerful, becomes red hot, the water that touches it evaporates, and the sheath of vapour Fig. 62.
which is thus interposed between the liquid and the electrode interrupts the circuit and gives rise to a spark. When the current ceases the platinum cools down, the electrolyte I h, mmm Fig. 63.
