Abstract

972,815. Rulers. CARL ZEISS JENA VEB. Jan. 10, 1962, No. 981/62. Heading B6P. [Also in Division G1] A graduated glass rule has a crosssection such that change in position of the graduations on the glass carrier due to bending of the rule is compensated by virtual displacement of the graduations viewed through the carrier. The rule may be of trapezoidal cross-section.
