Ideas and inventions in the GDR, 1987

In 1987, the GDR was tinkering with ideas and inventions that benefit the national economy and improve or simplify work in many areas. "Prisma" shows a technical aid for car repair, a process for the environmentally friendly separation of drilling emulsion and a method for cleaning beer lines. Insights into car body construction, the functioning of a lathe and its coolants as well as a flushing method for beer taps prove that technology is developing in the GDR.
