My products were conceived in 1986 through 1991. At the time I was working for Westinghouse Water Reactor Division. I am 60, retired, and now have had the time to work out the "kinks", on how to make my products viable and reliable. I find it interesting that no one has introduced one of my products that I conceived over 25 years ago. I have done an exhaustive patent search to make sure I am original.
