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.
