These publications reference the patents I was awarded for the deveopment of spark and arc sources to be used for applied spectrochemical analysis. The patents were all assigned to the Wisconsin ALumni Research Foundation. Licensing was done by Mr. Marvin Woerpel. Patent #2 has the record of being the patent owned by WARF that had the shortest time from its issue until first royalties were received by the University of Wisconsin.
