Abstract
The invention comprises measuring or responsive instruments, including (but not limited to) viscometers, having a music wire ( ) or like high tensile wire support between driving/driven shaft assemblies ( ) and appropriate mounting to eliminate drag, friction, radial misalignment, vibration problems, especially at high rotational speeds, and afford an enhanced accuracy and speed of measurement or other response of the instrument as a whole, including such specific features allowing large angular deflections or small ones (full scale under one degree) and axial and radial rigidity. The instrument can also be used with a plate for cone plate, oscillation and normal force measurements.
