Ernie Wells article - Popular Mining MagPlease understand that I am NOT suggesting that anyone infringe on the patent covering the Cleangold system.
Paraphrased from the USPTO, infringement is to manufacture, use, sell, import or induce others to manufacture.
The patentee, in return for PUBLIC divulgence, received the above EXCLUSIVE rights.
Infringement does NOT include talking about the patent, mentally dissecting the patent or analyzing the probable (in)efficiency.
The patent is published and by virtue of the US Constitution 1st Amendment, freedom of the press and freedom of speech, can be read, thought about, spoken about and should it merit it, ridiculed as just another vanity patent: no different from US patent #3,079,521.
I do not stand aside when threatened with lawsuits for exercising my Constitutional Rights.
Someone far wiser than me said something like, "All it takes for evil to flourish is for good men to do nothing."
I am not a lawyer and I don't play one on TV.
I would highly recommend reading the patent US#5927508 for yourself so as to avoid potential infringement in your construction efforts.
Each should always consider the potential outcomes of their actions.
Oh and looking at the Ernie Wells design and his use of magnetic sheeting, take a gander at the science of the magnetism in the magnetic sign material. Please notice the alternating magnetic poles induced in the sheeting during manufacture.

johnedoe, the article is copyrighted and still available in Volume 1 of the Popular Mining Encyclopedia.
I think you can still buy the set of 5 encyclopedias from Action Mining. Not exactly cheap, but I am glad I bought my set.
Old issues of the magazine can be found for sale occasionally on the web.
Not everything printed is in the public domain.
Ergo, you either gotta buy it, borrow it or use the inter-library loan system.
Never begrudge the producer/service provider their just rewards.
Not all products/services deserve ample compensation.
Caveat emptor.
