In the arrangement of apparatus indicated in Fig. 4 the cathodeis connected with the exterior resistance A which itself is in circuitwith two resistances of self-inductances S and S equal and anodes, A.^ A^, of aluminum placed in the valve with the 520 2fODON: ELECTROLYTIC RECTIFIERS. cathode are connected with the two terminals of the alternatingsource. The rectified current in the operating circuit is slightlyundulating, its strength i = 10 amperes, its , U = 55 alternating potential difference = 110 volts. In order to use both half cycles of the alternating current, fourvalves may be employed connected as in a Wheatstone examination of this arrangement shows that each half cycle ofthe current will always traverse two valves connected in series andthat the two successive half cycles are rectified in one direction andthat they add their effects upon an exterior circuit. The regulation. Fig. 5. of the output is effected by means of reactances of variable self-inductance and the output of the valves is limited by the cutoutfuses. The loss of energy effected in the valves is manifested inthe form of heat. The apparatus grows warm, and it is necessaryto maintain it at a constant temperature of between 30 deg. and40 deg. C. by means of external refrigeration. According to theoutput of the valves there may be utilized for this refrigerationexternal radiation, a cold curi-ent of air, or a cold current of the latter case the four valves are to be carefully insulated fromthe water. The model of the valve most in use is that constructedby Mors & Company of Paris. NODON: ELECTROLYTIC RECTIFIERS. 521 This valve is composed in its essentials of a prismatic vase oflead, of plate form, constituting the cathode. The vase is sur-rounded by sheet iron forming its support. The anode is analuminu
