Mnbt dtp IN REGULATING THREE BOILERS When Disston engineers started to specify the control instruments for their new power plant they were in something of a quandary. Not for many years had their Company purchased such equipment, and without recent experience as a guide, the proper selection was at first a problem. But selection did not remain a problem for very long. Disston uses temperature controlling instruments, in making saws, files, knives, armor plate, etc. Many of those instruments are LScS, and noted for satisfactory performance. Why not, then, reach over into this experi ence and specify L&N for power plant instrumentation ? Operations have amply justified the decision. The Mctermax Com bustion Control handles the heaviest load swings with ease. Micrnmax Temperature Recorders supply multiple-point records of steam, water, fuel gas and air, with outstanding dearness and legibility and the Micromax COj Recorders are proving here, as in dozens of other plants, that they need no more attention than do pyrometers and are a great help to efficient combustion. . All these instrument* are described in catalogs; just send for the ones you want. This L'iN Control Board con sists of panels for three 200,00ftlb/hr Riley steam - generators, used by Henry Disston ft Sons. Inc., in Philadelphia. U.S.A. It provides Metermax Combustion Control for the hotter furnaces. Micromax CO- Recorders and Micrnmax Temperature Recorders for steam, air and gas temperatures, and all the various other instru ments and gauges necessary for. efficient, convenient operation. Convenience of arrangement is half the battle for good control! Note how Micromax COj and Temperature Recorders are placed for easy cross-reference just above the Metennax Combusrion Con trollers. Strip-chart Recorder has chart tear-off device which makes it easy to remove chart in 1-day lengths like the 1-day charts of other instruments. I UUS A NORTHRuP COMPANY, 4110 STEWTOH AVC.
