Inventions



In a supplement ("Great Inventions that Changed the World") to the
periodical "American Heritage of Invention and Technology", featured are ten
top patents of all time. Numerous archival photos, diagrams from patents,
etc.  Top 10 are: Cotton Gin; Sewing Machine; Barbed Wire; Telephone; Light
Bulb; Machine Gun; Automobile; Airplane; Xerography; Transistor.   Full
articles on: Sewing Machine; Light Bulb; Machine Gun; Xerography.   This
supplement seems to have gotten lost from its companion, so I am not sure of
its exact date. I assume it's fairly recent, as it is not too dog-eared.
Edison graces the cover.
