One excavation was made for both units, and a solid mat of concrete, 8" to 12" thick, placed at the bottom of the foundation. Forms were built aDd the concrete poured so that the two founda tions were actually one continu ous mass of concrete, being joined at the outboard bearing. Insula tion, Yi thick, was then placed between the floor and foundations and between the foundations and the trenches, serving the exhaust steam lines and electrical conduits. These extra precautions were justified by the results. Not a trace of vibration can be felt in the floor or walls. All who have seen these units operating have commented on their quiet, smooth and ap parently effortless operation. The Brothers have expressed them selves as being well satisGed with their purchase. The large receiver type separa tors on each engineare Elliott Welderon separators. Elliott type "P" oil separators serve each of the exhaust lines from the engine. The new engine-generators are housed in a new engine room built for the purpose. Other changes and improvements were made at the same time, including the installa tion of a complete new switch board, consisting of two generator panels and three distribution pan els. The pump room was practi cally rebuilt. Anewfeedwaterheat er was installed and the feed water pumps lowered to a new pit, giv ing sufficient additional head to permit efficient removal of the feed water which is being heated to the temperature of the exhaust steam. The softener and the hot water heaters serving the laundry and general purpose requirements were moved to' a new tank room. All of this work was. accom plished without any interruption of services to the institution. That this could be done successfully was due to the very careful planning of Brother Julius, who, with the as sistance of Brother Alphonse, had complete charge of this moderniz ing program. One of the old releasing Corliss units which were replaced by the new equipment will be preserved for posterity and is to be placed on permanent exhibition in the Museum of Science and Industry now being built in Chicago. It is considered typical ofwhatwas best practice 35 to 40 years ago. And it is not entirely coincidence that, by its side, will be placed an El liott four-valve engine represent ing the best that is offered in mod ern engine construction. One of the too old 60-kw. engine-generator units which were replaced by the Elliott sets shown on page S5. The generator of the above unit is a Siemans-Hatskf, built SB years ago. The rotor is on the outside of the generator and the exterior surface of the rotor senes as the commutator. These units were typical of best practice S5 to iO years ago. [27] CRIMDEBN00000324
