| 摘要 | A DEVICE FOR MEASURING VARIATIONS OF PRESSURE, COMPRISING A DEFORMABLE ELEMENT IN WHICH THE ERRORS OF MEASUREMENT DUE TO THE PHENOMENON OF HYSTERESIS IN THE MATERIAL CONSTITUTING SAID ELEMENT ARE REDUCED SUBSTANTIALLY TO ZERO BY CHOOSING THE FORM OF THE DEFORMABLE ELEMENT AND THE THICKNESS OF ITS WALL IN SUCH MANNER THAT THE THICKNESS OF SAID WALL VARIES IN A LINEAR MANNER WITH THE RADIUS OF SAID WALL, WHEREBY THE STRESS-GRADIENT IS MADE SMALL OR ZERO THROUGHOUT THE WHOLE MASS OF THE MATERIAL OF THE DEFORMABLE ELEMENT. | ||||||
