INVENTIONS

1. Sine Wave Drafter: Plots sinusoidal waves (Sine, Cosine or arbitrary phase) of any amplitude, phase and wavelength; along linear or circular paths.
2. Fourier Drafter: Plots the sum of any number of sinusoidal waves with different amplitudes, phase, wavelength
3. Damped Wave Drafter: Similar to Fourier Drafter above, but also includes different damping coefficients for the waves, for plotting transients.
4. Archimedian Spiral Drafter: Plots Archimedial spirals of given pitch.
5. Archimedian Polygonal Spiral Drafter: Plots polygonal spirals (e.g. pentagon spiraling in) of given number of sides and pitch.
6. Geometric Polygonal Spiral Drafter: Plots polygonal spirals where length of each linear segment bears a constant ratio with the previous segment.
7. Conicograph: can plot conics - Ellipses, Paralolae, Hyperbolae of given eccentricity and parameters
8. Automatic Road Map Reader: Mechanically places a moving vehicle on a map of given scale.
9. Modified Differential: Reduces turning radius of a vehicle, by making it turn about the center of its live axel!
10. Coin Exchanger: With a 'mechanical brain', exchanges any combination of coins for another of identical value.

and a dozen more mechanical/electromechanical devices...
