TransactionsPublished under the care of the General Secretary and the Treasurer . l 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 analuminum alloy assuming the form of thin plate laminated at theedges, upon which is fixed a rod of aluminum forming the leadfor the current. This rod is insulated by means of a tube of rub-ber. The valves contain a saturated solution of neutral ammoniumphosphate. Cooling is accomplished by means of a lateral electricventilator. The Mors Company constructs standard sizes between1 and 100 amperes at 110 volts, whose operation is regular andconstant. The guaranteed industrial eflBciency of these valves variesbetween 65 and 75 per cent. Curves Obtained from Such an Arrangement. In Fig. 6 it will be seen that an alternating current underan alternating of 117 volts, at 53 cycles, furnishes a. rectified current at an of 83 volts. The strength of the alter-nating current is 5 amperes and that of the rectified current The output of the valve is not high, but this figurepossesses a certain interest, for it has been obtained with valvesmade with cathodes of polished steel plunged in a solution ofneutral ammonium phosphate, maintained at a constant tempera-ture of 9 deg. C. The apparatus has operated continuouslyand has carried 3800 ampere-hours. At the commencementof operation of a new valve, the is equal to 96 volts for therectified current (110 volts alternating). This soon dropsto about 80 volts, where it remains constant. The leakage isverv slight under normal conditions. 622 NODON: ELECTROLYTIC RECTIFIERS. The nature of the electrolyte plays an important part in thevalves. This action, in the case of a single valve, has already beenexamined. Determinations made w
