AUTUMN . POWERFAX . 1 9 3 3 dock makes an electric contact every two seconds and if the fre quency is not exactly 60 cycles, the little Telechron motor must bring it exactly right. In addition to the governor con trol, a Scutte and Koerting but terfly valve has been installed in the steam line to each engine ahead of the throttle valve, and any speed in excess of ISO r.pjm., will cause it to restrict the steam to the engine. The 16" main steam line is connected in the double loop sys tem, and each engine can be cut off by means of gate valves. Directly attached to each steam cylinder is a 10* Elliott Welderon receiver separator, the steam line leaving the overhead throttle valve, and forming a Siamese loop connection. Set about 30 feet from the floor is the motor-driven throt tle valve, which is operated by means of a push button to start and stop each engine. Elaborate lubricating systems are provided. An unusual feature is an electrically operated oil sup ply valve for each engine. This is a double magnet-operated solenoid globe valve, placed in the oil line of each engine and elec trically connected so that the throttle valve cannot be opened until the oil is flowing to the bear ings. Aswitchboard and controlbench occupy a comer of the engine room. In a high glass dome, .sur rounded by a guard rail, the mas ter Telechron clock operates. The main electrical switching and bus room is located below the engine room. Heating System Both steam and hot water are used for heating, hot water being favored for the hospital buildings. The highest floors are heated by steam. In such rooms as the de livery room and the maternity hospital, steam is used in connec- A close-up view of the governor and valve gear on one of the engine units. tion with or to supplement the hot-water system to insure reli ability. Both the steam and the hot-water systems receive their supply from the engine exhaust. There are numerous ventilating systems, and air conditioned spac es are scattered throughout the hospital. In the refrigerating sys tem, two Elliott 12' Twin Strain ers are located next to brine pumps. Dr. A. A. Adler, Consulting En gineer, writing in NATIONAL ENGINEER closes f' with this paragraph: "In examining the equipment in this hospital group, two things are forcibly brought to the attention of the engineer. Ob viously, in a hospital it is impera tive that the equipment be reliable and that the breakdown of any one piece of equipment does not neces sitate a complete shutdown. The designing engineers have not only selected the best equipment pos sible, but they have also dupli cated most of the equipment in the plant, so that trouble in any one piece of equipment will not seriously affect the functioning of any service. Undoubtedly, the years to come will see a continuous growth of this medical center. The designing engineers have provided plenty of room for future expan sion. With the passing of time, the value of these features will be realized and the foresight of these engineers will be appreciated. This vast project stands as a monu ment to progress, not only in the Held of medical science, but also in the field of mechanical engi neering--a true triumph of en gineering skill." Construction of the group of buildings comprising the New York Hospital - Cornell Medical College Assodatidn was started in 1929. Architects were Coolidge, Shipley, Bullfinch and Abbott, of Boston.
