An investigation of the fatigue properties of music wire and springs, which is now under way at the National Bureau of Standards, has resulted in the development of a reversed bending analysis method for predicting the approximate fatigue strength of helical springs wound from music wire. The study,
## Abstract **Summary:** 1‐(2′,2′,3′,3′‐Tetracyanocyclopropyl)‐3,4‐di‐2′‐hydroxyethoxybenzene (4) was prepared by the reaction of bromomalononitrile with 3,4‐di‐(2′‐hydroxyethoxy)benzylidenemalononitrile (3). The dipole moment of diol 4, calculated by the ASED‐MO method, was 4.01 D. Diol 4 was cond
