Description: |
| In 1964 Fairbanks, Morse Inc. changed its name to Colt Industries.
Abstract:
The low profile scale assembly includes a scale platform, a scale base unit, a load sensing means mounted on the scale base unit, and a parallelogram flexure linkage between the scale platform and base unit for applying vertical load forces to the sensing means. This flexure linkage includes first and second spaced, horizontally coplanar parallel elongated beams, the first beam being connected to the scale base unit and the second beam being connected to the scale platform. Upper and lower parallel, spaced flexure plates extend between the beams and provide little resistance to vertical load forces. The sensing means may include an electronic load cell connected to the second beam which provides a load signal to an electronic measuring circuit. |
