Yah.....We invented them and made the prototype for Vogtle. Then we had the real thing made by a vendor out of a spun fiberglass-kevlar composit. If you need any, let me know and I will contact the people who made them for us to see if they still have the tool-up available to make more.
Tarbox.....Thanx for the reference. We invented so much stuff and worked on so many patents, I had nearly forgotten all about that one. The credit for all of that stuff should be spread evenly between myself, Wayne Mandrell, Brad Pittman and Eddie Humphreys....(No particular order....That's just the order they put our names in in the patent paperwork.)
