Coil-measuring machine
Abstract
A machine was constructed to measure the diameters and axial positions of the turns of single layer coils used for realizing or monitoring electric units. The diameters are referred to a length standard previously measured in terms of the meter, but the axial positions are measured directly by an interferometer forming part of the machine. All results are punched on tape, and the desired property of the coil is solved by computer.
