Hi Joe,
I have never submitted anything to Wikipedia, but a friend of mine did and it was rejected several times. He was very knowledgeable on the subject, but didn't write well. Another friend who was good at writing edited it for him and it went through. He also had to add more references. Maybe you should have someone who is good with grammar/syntax, etc take a look at it for you. Not saying you don't write well, but a few mistakes in grammar or punctuation might have been the cause. It could be the lack of references too. I know you are an expert on the Veeder Root and would like to see you published there.
Good luck. John
