At point A all* flux is going through the right-hand From R down to T on the curve the 8qi decreases to zero, reverses end increase* to F in i short time. This rapid Qq* change induces a sharp peak voltage h the secondary, as indicated by curve This voltage, when applied to tbs grid of a gas-filled tube, can control current flow through the lube to within one-thoussndib part of a second. There are other constructions of these trans formers but they oil operate in the wij described. The next article will deal with espse* itors by themselves and in comblnitioa with reactors. Following this we will gel bock to electron circuits, beginning with rectifier operation. London Station (Continued from page 128) OariMId (III iiiuiontpri ikmx, 4-fSM UISSOUIII Kuw air. Hm. irn ft.

Eoch unit will have two 100%-ciparity boiler feed pumps running st. 3000 rpm. They will be interconnected on suction and discharge; of foot pumps, three will be motor driven and one steam-turbine driven. Coellnp-Wote* System. For the 6nt two units, four main circulating pump, are bring provided, each rated at 26,700 gpm so any three con supply tbs full cooling-water requirements of tbs two units. The circulating-water circuit will be of the siphonic type.
