    This was a major piece of early thinking on spread spectrum communications and frequency hopping–butter for the bread (or bread for the butter?) of wireless communication–with the piano roll tapes replaced by electronics. The idea didn’t go anywhere in 1942–it did, however, go far, beginning in the late 1950’s. The major name listed on the patent report is a major name, but not in this form, and not in this area–some might find it very surprising to know the more popular version of the inventor’s identity, and the industry in which the inventor worked.

    The original patent for this tube-and-rod design was made at the Danish Patent and Trademark Office in Copenhagen on 28 Jaunary 1958 at 1:58 p.m.  The design could be for an associated cooling system for a steam turbine; or for a high-pressure/reactive clutch of passes and cylinders for a water turbine hydroelectric facility; or perhaps it was for a modern prison system utilizing water-filled bars for prison cells that could indicate a possible jail break if any leaking water was discovered, making tampering with the bars an impossibility.
