AISE Paper. Skinner "Universal Unaflow"Steam Engines constantly increase in popu larity; for year after yeargives added testimony to their permanent econ omy of operation and maintenance. The efficiency of the patented design of the poppet inlet and auxiliary ex haust valves, steam-tight after tong use and under any variation ofsteam Sressure or temperature, has not een equalled by any other valve. While "Universal Unaflow" En gines are most popularly known for their economical generation of elec tric power, they are effecting equally important savings in driving blow ers, compressors, refrigeration equip ment, pumps, lineshafts, and other loads, by direct connection, cou pling, or belt drive. Skinner "Universal Unaflow" En gines are made in sizes for a wide range of applications, from 75 hp. to 3000 hp., in horizontal or multi cylinder vertical types. They are suit able for noncondensing or condcnsingoperation, with automatic change for either condition. They may be provided with special manual or au tomatic controls for variable speed and load requirements. An additional economy is fre quently gained by the use of exhaust steam for heating, processing tech niques, and other uses.
