This Kaplan turbine is one of the first three machines to be put into service in the United States. Named for its Austrian inventor, Viktor Kaplan (1876-1934), the turbine was an outstanding innovation, operating with a high, nearly constant efficiency over a wide load range. The machine was built by S. Morgan Smith Company of York, Pennsylvania.

This ironworks exemplified the adaptability required for industrial survival in a dynamic technical environment. It was a major western producer of mechanical equipment used in mining (especially large hydraulic machines), ship propulsion, irrigation, power generation, optical telescope mounts, and nuclear research.

This is one of several, similar inclines built in western Pennsylvania during the late 19th century. It was designed by Samuel Diescher (1839-1915) after the great flood of 1889, to provide an efficient means of transportation between Westmont and the Conemaugh Valley. (See also the Monogahela and Duquesne Inclines in Pittsburgh.)

The oscillating steam engine, built by John Penn & Sons, is located aboard the famed paddle steamer Diesbar. Diesbar is the second oldest of a fleet of nine paddle steamers in Dresden. What makes the Diesbar unique is its coal fueled engine and single deck design. The John Penn and Sons engine that runs the steamer is the oldest operational marine steam engine in the world. It has been in operation for over 165 years.

Although not the first four-wheel-drive vehicle or the first designed for rough, multipurpose field use, the Jeep MB was built as an unusual combination of these and other features of modern vehicle design in the World War II era.

The Jake Brake permits large trucks to descend long, steep grades at a controlled speed. It was the first practical mechanism for altering on demand the valve timing on a truck diesel engine, thereby converting the engine to a power absorbing machine. The modified engine can continue to power the truck in normal operation, allowing service brakes to remain cool for emergency situations. Invented by Clessie Lyle Cummins (1886-1968), this device (produced by the Jacobs manufacturing company since 1961) has contributed significantly to highway safety.

This facility was typical of others in the country that made small spherical lead shot for the fowling pieces of frontier settlers. Smelted lead from the nearby Austinville mines was melted at the top of the tower and poured through a sizing sieve to produce small droplets. Surface tension caused the molted lead to assume a spherical shape that solidified during its 150-foot fall. The shot was then collected in a water-filled kettle at the bottom of the shaft. The "drop process" was patented in England in 1769 by William Watts, a craftsman of Bristol, England.

Plans to build a rapid transit system in New York were first made in 1831. By 1868 the first elevated railway was erected. As the "El" became crowded, construction of an underground railway was proposed. Ground was broken on March 24, 1900. The original subway, which took opened October 27, 1904, ran 9.1 miles from City Hall to 145th Street and Broadway. The fare was a nickel. Extensions to the Bronx opened in 1905 and to Brooklyn in 1908, completing the first subway.

In operation since 1944, the Icing Research Tunnel is the oldest and largest refrigerated icing wind tunnel in the world. Technology developed there enables aircraft to fly safely through icing clouds. Two firsts include the unique heat exchanger and the spray system that simulates a natural icing cloud of tiny droplets.

Prior to 1909 the traditional fishtail bit scraped the rock and quickly dulled in service. The Hughes two-cone bit's revolutionary rolling action crushed hard-rock formations with twin cone-shaped, hardened steel bits, each with 166 cutting edges, revolving on bronze bearings shaped to provide a large surface with reduced friction.
