The Food Canning Industry Was Revolutionized In 1920, When The Continuous Rotary Pressure Sterilizer Was Introduced By Albert R. Thompson. Thompson Was Chief Engineer For The Anderson-Barngrover Co. Of San Jose, California, Now The FMC Corporation. The Sterilizer Cooked Canned Products Uniformly Under Pressure For Short Period At High Temperatures, Then Quickly Cooled Them Under Pressure To Prevent Swelling Or Bursting. It Operated Continuously At Speeds Of Up To 400 Cans Per Minute.

The first long underwater tunnel in the world designed for motor vehicle use was built from 1920 to 1927. The 29.5-foot-diameter, 8,500-foot-long twin tubes of this tunnel were shield-driven by the pneumatic method through extremely difficult river-bottom conditions that were overcome by the ingenuity and determination of its engineers, Clifford M. Holland, Milton H. Freeman, and Ole Singstad. They were the largest in the United States when built.

The Ljungstrom air preheater is a regenerative heat exchanger, invented in the 1920s and soon used throughout the world. Dr. Fredrik Ljungstrom, then technical director at Aktiebolaget Ljunstrom Angturbin, invented it for preheating combustion air in boiler plants, but the use has expanded to include energy recovery in combination with the removal of oxides of sulfur and nitrogen.

The largest mine hoist in the world, it serves the two incline skipways of Shaft No. 2, almost 9,300 feet long. The overhead winding drum has a diameter of 30 feet, of which the cylindrical center section is 10 feet long. The two 10-foot long end sections taper down to a 15-foot diameter. Wire hoisting ropes (almost 27 tons) could be wound onto a small end of the cylindrical drum as the other rope unwound from the cylindrical section.

In 1899, during the earliest days of the automobile revolution, A. O. Smith developed a new, lightweight steel car frame. Within a few short years, he was selling these frames to a “who’s who” of car makers including Cadillac, Oldsmobile, and Ford. A. O. Smith’s son, Lloyd Raymond, carried on the family company, expanding the automotive business and introducing the world’s first automated frame production line, the Mechanical Marvel.
