At the beginning of the second world war, Vannevar Bush led a team to develop Mechanical gunnery computers. They were able to use the differential equations necessary for accurate calculations by the use of glass plate integrators. But the output of these integrators was too weak to drive the next term in the equation. A double capstan torque amplifier twas the solution. Theirs were much smaller and more precise than mine.
