Yes, and NO, Jerry. There are trade secrets that old timers took to their graves that have yet to be rediscovered. For instance, back in the mid 19th century, Franklin Stoves were often made and sold with a decorative clay or "ceramic" piece that fit on the door of the stove. To this day, we can now make ceramic reproductions of these decorative pieces, that will withstand the expansion and shrinkage of being heated and cooled in a stove, but scientist and ceramic engineers have not yet found out How those originals were made.
And, my late friend, Oscar Gaddy, " Re-discovered" Bone Charcoal Case Hardening, after finding almost a dozen different "formulas" for the process in sources both here in the USA and in Europe- NONE Of which worked as written. The one step left out of ALL of the formulas was the need to aerate the water for the quench for at least a half hour before quenching. There were other missing "steps" from each of the formulas he found, but by finding them all, and putting them side by side, he was able to find those missing steps. However, It took consultation with a Professor of Metallurgy, and a Professor of Chemical Engineering( Oscar was a Professor of Electrical Engineering, and created the new Dept. of Electronic engineering at the U of Ill. ) to figure out that softening the water would produce the best colors.
Finally, when my Father left Sun Electric Co. in 1941 to work for Western Electric Co., he took with him his hand drawn electrical schematics for all the Sun Electric motors he worked on and repaired for the company as their " fix-it" guy. When I asked him why he took them, his comment was, " They didn't pay me for these!".
I suspect that this is the Reason so many people who have " Trade Secrets" still guard them jealously, and take them to their graves. In my father's case, had the company had the foresight to pay my father for his drawings, they could have hired Anybody to do his work. He tore down used motors that were sent in by customers, found out what was worn out or broken, Fixed them, and sent the motors back to the customer. During the Great Depression, when he was working for Sun Electric, people were sending in motors for early refrigerators sold before Dad was born. The company had kept NO records on those motors, so Dad had to take them apart, figure out how they were designed( UGH!) and repair them. People simply could not afford to replace their refrigerator. In many cases, they had a hard time coming up with enough money to ship the motors to the company for repairs. My father remembered he was making $24.00 a week at Sun Electric when he quit the company to earn $28.00 per week working for Western Electric. That was in September, 1941. Dad showed me his "Trade Secrets" before his death in the mid-1990s. :hatsoff: :grin: :hmm: :thumbsup: :thumbsup:
