Obsolete Tube Cleaners waste time, labor, and money Even If you rarely use tube deanori, you can't afford to be without a powerful new ROTOJET. A ROTOJET should save you enough In time, labor* and air In one cleanout to poy for itself. You won't believe a tube cleaner can pack such tremendous power until you try the new ROTOJET. 242 lion, since Kodok Park extends on, considerable area.

There is a 12 jn pipe line transmitting at 260 psl to Bldg 101 with an extension to the area still further west, a mile and a half from Bldg. 31. We are now in the process of supplementing the 12-in. msin with a 5,000-fl., 20-in. pipe line to sopply siesta for the new turbine previously mentioned and also, expected increases in load in the western areas of the plant.
