Flatcat no problem at all with being analytical, I am extremely analytical myself! By the way, I liked your electrical drawing it was very educating. Here are the patent numbers that you requested: I just called the US Patent office to end this discusssion and to confirm my findings and yes they are all approved - there are 3 filings related to Kryron - Patent #'s are 7870886, 7870887 and 7767121. The differences in the patents and in the Claims section if you look these up on the US Patent website I gave earlier. They are all approved patents and the first 2 were approved 1/18/11. I also emaield the WIPO and will wait to hear from them and post the results. Thanks
