The best relic from my days as a design engineer is the patent that I obtained for my work on printing equipment while at Gämmerler Corporation. I took out the patent for a “refeeder” machine that takes stacks of magazines or other printed material and directs them into a shingle stream for further finishing (cutting, folding, etc). For more details see the Google Patent site for the innovation at: http://www.google.com/patents/EP0857674A2?cl=en or http://www.google.com/patents/EP0857674A3?cl=en
Here is a schematic that I drew on CAD. More images of the actual design are available at the websites.
Enjoy responsibly.
