In the current DGJ, Vol. 20, Issue 3(Autumn 2009) at page 20, Fredrik Franzen has a very interesting article on Gebruder Merkel and he includes Patent 509779 and states: "The Merkel patent from 1930 for a combination of mechanical and low-temperature soldering called "Weichlot," for over-and-under barrels."

The epoxy term I was looking for is " zwei komponenten kleber "( two component glue ), which Mike Ford kindly supplied to me.
