Strange Inventions

My current project involves the US Patent Office. In randomly searching patents I came across Patent #5782779 for a vibrating tampon which first showed up in the US Patent Office June of 1947 and is currently not available to the general public because they are "…in the process of developing high speed manufacturing equipment." I would hope the vibrator would have a high speed! The ladies will have to wait until late 2007.

Btw, I found it randomly after growing tired of looking at Patent #5000000 for Ethanol production by Escherichia coli strains co-expressing Zymomonas PDC and ADH genes.
