Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
126 words
THE METHOD OF MAKING VIBRATION ABSORBING MATERIAL WHICH INCLUDES THE STEPS OF SUPERPOSING A PLURALITY OF LAYERS OF FIBROUS MATERIAL AND A PLURALITY OF LAYERS OF PLASTISOL, AT LEAST ONE PLASTISOL LAYER AND AT LEAST ONE MEDIATE TWO ADJACENT FIBROUS LAYER A AND AT LEAST ONE PLASTISOL LAYER BEING DISPOSED EXTERIORLY OF ONE OF SAID ADJACENT FIBROUS LAYERS, SAID PLASTISOL COMPRISING A DISPERRATIO OF RESIN TO PLASTICIZER IN SAID INTERMEDIATE PLASTICIZER LAYER BEING DIFFERENT FROM THE RATIO OF RESIN TO PLASTICIZER IN SAID EXTERIOR PLASTISOL LAYER, POLYMERZING BY HEAT SAID EXTERIOR PLASTISOL LAYER AND FORCING BY MECHANICAL PRESSURE THE FIBERS OF SAID ONE FIBROUS LAYER INTO SAID EXTERIOR LAYER WHILE THE LATTER IS STILL SOFT AND PLASTIC, AND THEREAFTER POLYMERIZING BY HEAT THE INTERMEDIATE PLASTISOL LAYER
Claim 2
Independent Claim

Claim 3
Dependent Claim
86 words
A VIBRATION CHECKING PAD COMPOSED OF A PLURALITY OF LAYERS OF FIBERS BONDED TOGETHER AND PERMEATED THROUGHTOUT WITH POLYMERIZED PLASTISOL, SAID PLASTISOL COMPRISING FINELY DIVIDED VINYL RESIN DISPERSED IN LIQUID PLASTICIZER, THE WEIGHT RATIO OF RESIN TO PLASTICIZER IN THE PLASTISOL BEING DIFFERENT IN ONE PORTION OF THE THICKNESS OF THE PAD FROM THE WEIGHT RATIO OF RESIN TO PLASTICIZER IN THE PLASTISOL IN AN ADJACENT PORTION OF THE THICKNESS OF THE PAD TO PROVIDE A HETEROGENOUS STRUCTURE HAVING STRATA OF DIFFERING NATURAL FRAQUENCIES OF VIBRATION.
Claim 4
Dependent Claim
86 words
