Lagrange Equations
Joseph Louis Lagrange (Jan 25, 1736, Turin, Italy –April 10, 1813, Paris, France)
• Pupin studied Lagrange Equations. Later he used this theory to calculate wave speed, what was foundation for long distance telephony.
• Lagrange’s paper: “Research sur la nature et la propagation de Sou” - basis for Pupin’s invention of loaded line in telephone signal transmission
![Page 18: Pupin 2015 10 pictures](https://reader030.vdocuments.net/reader030/viewer/2022013004/58885b7a1a28abad0d8b4675/html5/thumbnails/18.jpg)
1885-1887 - Oliver Heaviside (1850-1925)—An inventor who
failed to file crucial patents
• Patent GB 1407 – 1880, Coaxial-Cable• 1892 – attend Tesla presentation held
in British Electrical Engineers Institute: “Experiments with high voltage, high frequency alternate
currents” • In 1885 and 1887 in British magazine
Electrician stated: “Without sufficient inductance (word first used in English Language), permitting energy to be stored in the magnetic field of the
line, efficient transmission would not be possible and much of the energy of the signal would be transformed into
the heat” 1900 – 15-13 yr
![Page 19: Pupin 2015 10 pictures](https://reader030.vdocuments.net/reader030/viewer/2022013004/58885b7a1a28abad0d8b4675/html5/thumbnails/19.jpg)
Heaviside coined the following terms of art in electromagnetic theory:
Electromagnetic terms• admittance (December 1887);• conductance (September 1885);• electret for the electric analogue of a
permanent magnet, or, in other words, any substance that exhibits a quasi-permanent electric polarization (e.g. ferroelectric);
• impedance (July 1886);• inductance (February 1886);• permeability (September 1885);• permittance (later susceptance; June
1887);• reluctance (May 1888).

Pupin’s Coil• Pupin's 1894 patent "loads" the line
with capacitors rather than inductors, a scheme that has been criticised as being theoretically flawed and never put into practice.
• One variant of the capacitor scheme proposed by Pupin does indeed have coils.
• These are not intended to compensate the line in any way. They are there merely to restore DC continuity to the line so that it may be tested with regular equipment.
• Pupin states that the inductance is to be so large that it will block all AC signals above 50 Hz. (Start fight with Tesla)
• Consequently, only the capacitor is adding any significant impedance to the line and "the coils will not exercise any material influence on the results before noted

Heviside-Pupin Legal BattleCampbell was the first to actually construct a telephone circuit using loading coils.
Heaviside never patented his idea; no commercial advantage of any of his work. Heaviside was the first to publish and many would dispute Pupin's priority.
AT&T fought a legal battle with Pupin over his claim. Pupin was first to patent but Campbell had already conducted practical demonstrations before Pupin had even filed his patent (December 1899). Campbell's delay in filing was due to the slow internal machinations of AT&T. AT&T foolishly deleted from Campbell's proposed patent application all the tables and graphs detailing the exact value of inductance that would be required before the patent was submitted.
Since Pupin's patent contained a (less accurate) formula, AT&T was open to claims of incomplete disclosure.By January 1901 Pupin had been paid $200,000 /$4.36milUSD2012 and by 1917, when the AT&T monopoly ended and payments ceased, he had received a total of $455,000 /9.9milUSD2012

Benefit to AT&T
It has been estimated that AT&T saved $100 million in the first quarter of the 20th century.
