Society: ASME Main Category: Mechanical Sub Category: Solid Waste Era: 1960-1969 DateCreated: 1969 Newell Industries San Antonio State: TX Zip: Country: USA Website: http://www.asme.org/about-asme/history/landmarks/topics-m-z/solid-waste/-179-newell-shredder-%281969%29, https://www.asme.org/getmedia/2c664309-172d-48d9-a822-5327e310a107/179-Newell-Shredder-1969.aspx Creator: Newell, Alton

This machine, designed by Alton S. Newell, efficiently reduced automobile bodies into scrap metal for recycling. A body was fed into the shredder at a controlled rate, and rotating hammers, driven by a 500-hp motor, shredded it into small pieces that were easily shipped. The process took about 10 minutes a car and used less energy than other shredding and crushing machines.

Dunlap's Creek Bridge
Society: ASCE Main Category: Civil Sub Category: Bridges Era: 1930-1939 DateCreated: 1939 Dunlap's Creek Brownsville State: PA Zip: 15417 Country: USA Website: http://www.asce.org/Project/Dunlap-s-Creek-Bridge/ Creator: Delafield, Richard , U.S. Army Corps of Engineers

Not only was Dunlap's Creek Bridge the first cast-iron bridge in America, it was the first metal bridge anywhere to use what its builder, Capt. Richard Delafield, U.S. Army Corps of Engineers, described as "standardized, interchangeable, manufactured parts." The bridge was built as part of the federal government's effort to make repairs on the National Road  before handing authority over to the states. Dunlap's Creek at Brownsville was an especially troublesome crossing, having destroyed three previous bridges since 1801.

Split-Hopkinson Pressure Bar Apparatus
Society: ASME Main Category: Mechanical Sub Category: Materials Handling & Extraction Era: 1960-1969 DateCreated: 1962 Southwest Research Institute San Antonio State: TX Zip: 28510 Country: USA Website: http://www.asme.org/about-asme/history/landmarks/topics-m-z/materials-handling-and-excavation/-242-split-hopkinson-pressure-bar-apparatus-%281962%29, https://www.asme.org/getmedia/a82d72ab-e923-4aa9-a296-784c3fb7463a/242-Split-Hopkinson-Pressure-Bar-Apparatus.aspx Creator: Lindholm, Ulric

The Southwest Research Institute Split-Hopkinson Pressure Bar apparatus is a mechanical test instrument used to characterize the dynamic response of materials at high strain rates (typical of impacts and explosions).

The apparatus, based on devices invented by Bertram Hopkinson and Herbert Kolsky, was developed at SwRI in 1962 by Dr. Ulric Lindholm. Initially created to evaluate the behavior of metals under various conditions, the SwRI Split-Hopkinson Pressure Bar has since been applied to a wide range of materials.
