Excerpt from Variance of Measuring Instruments and Its Relation to Accuracy and Sensitivity
The ?exible connector has another important property which has been utilized to a considerable extent in the design of auto matic scales, viz, that a correction of the motion of the parts to obtain a linear or uniform scale of graduations can readily be secured by arranging that one or both ends of the tape wind upon a cam of suitable contour, a feature whose importance will readily be appreciated. It does not seem that the use of the ?exible connector in such instruments as pressure gages (including ane roids) recording thermometers, hygrometers, tachometers, and the like has been as extensive as the favorable properties of the device warrant, and a marked improvement in the constancy or reproducibility of reading of such instruments should be secured by employment of this arrangement. Critical examination of the usual pressure gages and tachometers, as well as complex record ing instruments generally, will convince one that the importance of special care in the design of the turning pairs in the linkwork has not been commonly appreciated, and it does not seem that the best practicable performance of such mechanisms has been approximated.
