Induction type telemetering system

Claim 1

A displayed measurement translator device for providing coded measured values, said device comprising, in combination: a digit wheel stepwise rotatable through incremental rotations of one tenth of one complete rotation thereof and havIng thereon 10 decimal digits, each of said digits corresponding to one of said incremental rotations of said digit wheel; a disc-shaped encoding portion provided on said digit wheel, said encoding portion having four coupling openings circumferentially disposed thereon, said openings being divided into two groups each including two openings, said groups of openings being positioned such that the two openings of the first of said groups are located at selected two of 10 positions, corresponding to said 10 digits, circumferentially disposed at equal angular intervals on said encoding portion, and that the two openings of the second of said groups are located at two successive of said positions spaced away from the positions of said first group by one position; five driving windings disposed adjacent one surface of said disc-shaped encoding portion at alternate ones of said 10 positions and continuously energized with an alternating current; five output windings, each disposed in opposing relationship with one of said driving windings on that side of said encoding portion opposite from said driving windings; and the arrangement being such that at each position of incremental rotation of said digit wheel one only of said groups of openings is aligned with one of said opposed output and driving windings, and those output windings aligned with said two openings of said one group are electromagnetically coupled to the opposed driving windings through said two openings to provide a voltage signal representing that digit in the form of a two out of five code representative of said each position of incremental rotation of said digit wheel.
