Balance with optical display - gives direct visual read=out and has moving and fixed transparent number scales and projector

摘要

A balance with an optical number display has a scale carrier moving according to the measured wt. with a transparent number section, a light source, and an objective for projection of a moving scale image onto a screen. A stationary scale with transparent number section is placed near the screen. - It is designed for direct optical read-out without additional operations or evaluation whilst maintaining improving on existing balance accuracy. A transparent gap is placed beside the lowest position numeral of each number. It forms an image no larger than the distance between two numbers on the fitted scale. - The screen is large enough to permit only one complete moving scale figure to be shown.
