Guest imported_Bookreader Posted July 12, 2004 Share Posted July 12, 2004 Here I am again reminding you and everyone to always go to our AACA Library and Research Center for information. We may have something for you there. Go to the AACA Home page and click on library for the front door entrance into our Library and to meet our librarian Kim. If Kim does not have the information she may be able to guide you to someplace for it. Link to comment Share on other sites More sharing options...
jasaflower Posted July 12, 2004 Author Share Posted July 12, 2004 Thank you for such a prompt answer But I live in the UK and felt I would try my luck online rather than on a phone line.It seems that on this museums' web page which you are pointing out, there isn't an online records search to find out if they even have what I am looking for. I am sure you know the rates can be quite costly for a phone call from here to the States. (The Library of Congress doesn't even have anything on this guy!) However, I will most definitely keep your suggestion as an option. Hmm.. actually you wouldn't happen to have an e-mail address for the museum? Didn't see one on the site either. All advice is welcome and appreciated so if you or anyone else has any further advice, avenues or 90 year old relatives with newspaper clippings & pictures, anything shy of me incurring a £90 phone bill and 2 weeks waiting for snail mail please please please don't hesitate to reply. Thanks again for your time & Happy trails!! Link to comment Share on other sites More sharing options...
Peter J.Heizmann Posted July 13, 2004 Share Posted July 13, 2004 Hello, jasaflower...Welcome to the AACA Forum. By all means, please stay tuned and involved. Collectively, all of us are here to assist eachother. New members to our forum require guidance to navigate, so, bookreader's post, I assume, was directed at "regular forum participants" that, either, do not know how to take advantage of our club's noted services, or, some that take a short cut.A phone call is not necessary. Look at the immediate left column, click on Antique Automobile Club of America, click on AACA Library, click on Research Request Form...the rest is explanatory. There is a charge, however, should you not receive satisfactory, if any, assistance on the internet, the nominal fee may be well worth the cost.I have a 1972 Triumph TR-6 (original owner). To obtain build records from the British Motor Heritage, it cost me $40.00, so, this subject is relative.Regards,Peter J. <img src="http://www.aaca.org/ubbthreads/images/graemlins/grin.gif" alt="" /> Link to comment Share on other sites More sharing options...

Guest imported_Bookreader Posted July 13, 2004 Share Posted July 13, 2004 Here we go! thanks to ye ol computer and all it holds I have some information for you.Around 1920, William Potts a Detroit policeman, invented (unpatented) several automatic electric traffic light systems including an overhanging four-way, red, green, and yellow light system. The first to use a yellow light. This was gleaned from simply going on the web and looking for William Potts, traffic lights.Go to http://inventors.about.com/library/inventors/blasphalt.htm Link to comment Share on other sites More sharing options...
