Patent Beauty (5)
We enter the world of registered trademarks now with our next stamp.
I cannot seem to find all the symbols here in this programme so forgive me for just saying that there should be an R in a circle following every mention of the word Dyneema. And Dyneema is the subject of our 1979 patent stamp. It is a super strong fibre, which apparently is even stronger than steel! Dyneema is often used in ropes, cables and fishing nets. It is invented by the Dutch company DSM, the current version of what used to be the Dutch State Mines in the early 1900s.
Designwise: Note how part of the invention is highlighted in a circle on every stamp.
