Claims Analysis
Total Claims: 2
Claim 1
Independent Claim
108 words
IN THE PROCESS FOR MEASURING VISCOSITY IN WHICH A MEMBER IS PERIDICALLY AT GIVEN TIME INTERVALS MOVED THROUGH THE MATERIAL UNDER TEST AND THE RESISTANCE TO MOVEMENT IS RECORDED AS A MEASUREMENT OF VISCOSITY, THE RESISTANCE TO SAID MOVEMENT BEING ADDITIONALLY USED TO DETERMINE A CHANGE IN THE ELASTICITY OF THE MATERIAL, THE IMPROVEMENT COMPRISING EFFECTING AT LEAST ONE ADDITIONAL QUICKLY SUCCEEDING MEASUREMENT OF THE RESISTANCE TO MOVEMENT OF THE MEMBER DURING EACH PERIODIC MOVEMENT, THE TIME OF MOVEMENT OF THE MEMBER BEING RELATIVAELY SHORT AS COMPARED TO THE TIME INTERVAL BETWEEN MOVEMENTS, WHEREBY WIDE VARIATION OF THE RESISTANCE IN SAID SUCCESSIVE MEASUREMENTS INDICATED ELASTICITY IN THE MATERIAL.
