Military Cable Layer-extractors Inventions

In 1966-75, S.I. Fishgal, as a leading designer for the Soviet Communications Corps, among his 500 Soviet patent applications, made his military cable layer-extractor manufactured 25 years. No known ones extracted cable. His machine was driverless to track along and keep the digger near the buried cable. Vibration digging he invented too. The author’s other engineering books: "Applied Mathematics in Inventions", “Applied Cavitation Inventions”, “Applied Hydro-Impact Inventions”, “Automotive Inventions”, "Rock Crushers Inventions”, "Highways and Concrete Inventions". His intriguing truthful historical books novels: "Piddler on the Hoof", "Kosher Hooks", "Mein Krampf". The horse sense, crisp and funny language, topsy-turvy idioms, and plays of words are striking. He is hopefully neither the worst novelist of inventors, nor the worst inventor of novelists.
