Did anybody realise that today is the 218th Anniversary of the first US patent? It covered a method of making potash and pearl ash (potassium carbonate), important ingredients for making glass, china, soap and fertilizer. It wasn't patent No.1, though. See http://www.wired.com/science/discoveries/news/2008/07/dayintech_0731 for more.
