Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
81 words
An assembly comprising: a. pneumatic tire; b. a vehicle wheel having a tire-mounting rim with said tire mounted on said rim forming a cavity between the interior of the tire and rim; and, c. said cavity filled with a solid, resilient composition comprising a mixture of: 1. an elastomeric material; 2. hollow spheres having diameters ranging from 10 to 300 microns, with said spheres dispersed throughout the elastomeric material and the elastomer cured, thereby forming a solid filling of said cavity.
Claim 2
Dependent Claim
81 words
An assembly comprising: a. pneumatic tire; b. a vehicle wheel having a tire-mounting rim with said tire mounted on said rim forming a cavity between the interior of the tire and rim; and, c. said cavity filled with a solid, resilient composition comprising a mixture of: 1. an elastomeric material; 2. hollow spheres having diameters ranging from 10 to 300 microns, with said spheres dispersed throughout the elastomeric material and the elastomer cured, thereby forming a solid filling of said cavity.
Claim 3
Dependent Claim
30 words
hollow spheres having diameters ranging from 10 to 300 microns, with said spheres dispersed throughout the elastomeric material and the elastomer cured, thereby forming a solid filling of said cavity.
Claim 4
Dependent Claim
30 words
hollow spheres having diameters ranging from 10 to 300 microns, with said spheres dispersed throughout the elastomeric material and the elastomer cured, thereby forming a solid filling of said cavity.
Claim 5
Dependent Claim
39 words
The assembly in claim 1 wherein the elastomer consists essentially of a two-component polyurethane system which, when said components are combined and cured, makes a resilient solid material having a durometer of about 40 on the Shore A scale.
Claim 6
Dependent Claim
48 words
The assembly in claim 2 wherein the hollow spheres are made of glass having a true partial density in the range of 0.200 to 0.350 g./cc. and particle diameters ranging from 10 to 300 microns, with an average wall thickness in the range of 1 to 2 microns.
Claim 7
Dependent Claim
14 words
The assembly in claim 1 wherein the hollow spheres are made of ceramic materials.
Claim 8
Dependent Claim
22 words
The assembly in claim 1 wherein the hollow spheres occupy from about 10 to 25 percent of the volume of the cavity.
Claim 9
Dependent Claim
23 words
The assembly in claim 1 wherein the hollow spheres occupy from about 10 to about 50 percent of the volume of the cavity.
