Highways and Concrete Inventions

In 1963-75, among novelties described in his 600 patent applications and publications, S.I. Fishgal pioneered in highway and bridge building field, including using cavitation, ultrasonics, driverless tracking, etc. Then he became stateless, paperless and almost nameless. Naturally, his unpublished works vanished. The author's other engineering books are "Rock Crushers Inventions", "Military Cable Layers-Extractors Inventions", "Applied Cavitation Inventions", "Applied Hydro-Impact Inventions", "Automotive inventions". His historical novels are "Piddler on the Hoof", "Kosher Hooks" and "Mein Krampf". Hopefully he is neither the worst inventor of novelists, nor the worst novelist of inventors.
