The simple solution ol the problem Is the Installation ol a Wing Electric Heater (shown at the upper right) which Is set in operation by a dewpoint control (shown on the wall below the healer). At the (list Indication of excess mois ture In the air, the dewpoint instrument sets the Wing Electric Heater into operation, healing and reclreulatlng the air in the room and removing all danger ol dampness and corrosion. Wing Electric Healers have many applications, not only la the electric utility. Held, but wherever heal i$ necessary at remote points or where eteem or gat is unavailable or un economical. L. J.

Ceneral Electric Co, Schenectady 5,. New York There's no avoiding the fact that a turbine requires protection from (wo troublemakers-- dirt and water. Any device that removes only the dirt does only half a job. That is why De Laval Oil Purifiers are so much more effective for maintaining the purity of turbine oil than any other means available. They not only remove solid contaminants but also any moisture that may be present. ' It is important to get such double protection, for oftentimes water, rather than dirt, is the real source of contamination. For example, condensate in oil leads directly to the forma tion of sludge, and, of course, if a water leak should ever develop, serious emulsification and real trouble might occur. De Laval Oil Purifiers do not remove oilsoluble additives. The purifying action is entirely mechanical.^ THE DE LAVAL SEPARATOR COMPANY PoushltMpiIt, NtwYoiV . 487 Randolph St., Chkago 6 DE LAVAL PACIFIC CO. 61 B.l Si, San Frad S THE DE LAVAL COMPANy,Umll.d.Pd.rbo.ooih,Oni DE LAVAL Scintillation Counief* - 1233 New selnillUtbo survey m scintillation drill-hole, probe-lype. drily detector ere selUeoUlnod, bauwr [Continued on page 198) town otcemui ' 'fOVrtft OECCM6EC 1933
