These two water turbines were probably the largest and nearly the most powerful ever built in the United States, supplying direct mechanical power to a manufacturing plant. Their installation between 1871 and 1873 makes them among the oldest surviving water turbines.
A dam at Cohoes diverted water to mills and factories along a power canal system. The vertical-shaft turbines at the mill were said to run at 800 horsepower (600 kilowatt) under a head of 20 feet and were connected to an overhead shaft by bevel gearing.

This is the first commercial, human-blood heat exchanger. Developed in 1957, it permitted a patient's body temperature to be safely and rapidly lowered during open heart surgery to any desired and precisely controlled hypothermic level, then during the conclusion of the operation rapidly rewarmed to normal. Prior to this, hypothermic surgery required hours of preoperative, hard-to-control, external emersion cooling and postoperative rewarming.
Its design was a cooperative development between researchers at the Duke University Medical Center led by Dr. Ivan W.

The ballpoint pen invented by Ladislao Jose Biro was originally patented in Hungary in 1938. The principle of the ballpoint pen was originally patented by John Loud in 1888 for a product to mark leather and in 1916 by Van Vechten Riesberg, but neither of these products were exploited commercially.
As a journalist, Biro was inspired by the concept of quick-drying ink in a print shop.

When built in 1962, this shovel was the second largest in the world. It was used for the removal of overburden in the surface mining of thin coal seams. In its lifetime, it recovered nine million tons of bituminous coal from depths of 20 to 50 feet for local electric power generation. Standing 160-feet high, weighing 5,500 tons, and moving at speeds up to two-tenths of a mile per hour, the machine stripped about a square mile each year.

This unit, retired from the Belle Isle Station of the Oklahoma Gas & Electric Company, was the first gas turbine to be used for electric utility power generation in the United States. It represents the transformation of the early aircraft gas turbine, in which the engines seldom ran more than ten hours at a stretch, into a long-life prime mover. This redesign was based upon creep-rupture tests of S-816 cobalt-base alloys for turbine buckets. The low-cost trouble-free service led to wide-scale adoption of the gas turbine, over 45 million kilowatt capacity (over 9 percent of U.S.

Built by the Bay City Dredge Works of Bay City, Michigan, this dredge was used to construct a portion of US 41 called the Tamiami Trail, which connected Tampa with Miami through the Everglades and Big Cypress Swamp. The last remaining display of walking dredges (of some 145 walking machines), it has a unique propulsion design enabling the dredge to cope with drainage problems in a wetlands environment.

This is one of the three original 60-ton vessels by which the basic oxygen process (BOP) of steel making was introduced into this country from Austria, where it was invented. It heralded the first new technology in fifty years to become the basis of a major process for steel production throughout the world. In this process, a water-cooled lance injected a jet of high-purity oxygen into the bath of molten iron. Various chemical reactions produced a quality low-nitrogen steel at a ton-per-hour rate nearly three times that of the open hearth furnace.

The Atlas E-2 Space Booster, or launch vehicle, is a modified intercontinental ballistic missile developed by the Convair Division of General Dynamics and the U.S. Air Force. The basic concept of the Atlas system was proven in its first flight on June 11, 1957, followed over the years by the launching more than five hundred vehicles including the Pioneer, Ranger, Mariner, and Surveyor. Many payloads were sent into orbit as detachable sections of Atlas missiles.

With a water table several feet below ground level, New Orleans faced a crisis after every heavy rainfall, not just through flooding but also through disease (yellow fever and malaria) caused by impure water. New Orleans was dependent on mechanical means for lifting water from its canals and sewage systems.
A. Baldwin Wood (1879-1956), a young assistant city engineer, designed and installed a system of large screw pumps (axial flow machines) to syphon water and accelerate drainage. By 1915 the Wood screw pump became the most advanced drainage pump in use.

The Apollo was the vehicle that first transported humans to the moon and safely back to earth. Nine lunar flights were made between 1968 and 1972. The command module, built by North American Aviation (at the time of launch, North American Rockwell Corporation), accommodated three astronauts during the mission. It was the only portion of the Apollo spacecraft system designed to withstand the intense heat of atmospheric re-entry at 25,000 mph and complete the mission intact. This command module at Rockwell flew as Apollo 14 in 1971.
