Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
128 words
A process for applying an insulating mixture onto an object and for thereby building-up the insulating mixture on the object to a desired thickness, the process including mixing together in a container a fiber adhesive mixture of about 40% sodium silicate and about 60% acrylic resin and agitating them together sufficiently to form a homogenous mixture, mixing water with the adhesive mixture in a container so that the ratio of water to adhesive mixture is about 3.5 to 1 by volume, mixing insulating fiber with the adhesive-water mixture so that the ratio of fiber to adhesive-water mixture is about 1 lb. fiber to about 1/4 gallon adhesive-water mixture, introducing the fiber-water-adhesive mixture into an application apparatus, and applying the fiber-water-adhesive mixture onto an object to a desired thickness.
Claim 2
Dependent Claim
128 words
A process for applying an insulating mixture onto an object and for thereby building-up the insulating mixture on the object to a desired thickness, the process including mixing together in a container a fiber adhesive mixture of about 40% sodium silicate and about 60% acrylic resin and agitating them together sufficiently to form a homogenous mixture, mixing water with the adhesive mixture in a container so that the ratio of water to adhesive mixture is about 3.5 to 1 by volume, mixing insulating fiber with the adhesive-water mixture so that the ratio of fiber to adhesive-water mixture is about 1 lb. fiber to about 1/4 gallon adhesive-water mixture, introducing the fiber-water-adhesive mixture into an application apparatus, and applying the fiber-water-adhesive mixture onto an object to a desired thickness.
Claim 3
Dependent Claim
62 words
An insulating mixture for spraying onto an object to insulate the object and for thereby building up the insulating mixture on the object to a desired thickness, the insulating mixture comprising about 50% water, about 17% adhesive, the adhesive comprising about 40% sodium silicate and about 60% acrylic resin agitated together sufficiently to form a homogeneous mixture, and about 33% cellulose fiber.
Claim 4
Dependent Claim
62 words
An insulating mixture for spraying onto an object to insulate the object and for thereby building up the insulating mixture on the object to a desired thickness, the insulating mixture comprising about 50% water, about 17% adhesive, the adhesive comprising about 40% sodium silicate and about 60% acrylic resin agitated together sufficiently to form a homogeneous mixture, and about 33% cellulose fiber.
Claim 5
Dependent Claim
81 words
An insulating mixture for spraying onto an object to insulate the object and for thereby building up the insulating mixture on the object to a desired thickness, the insulating mixture comprising about 50% water by weight, about 33% insulating fiber by weight and about 17% fiber adhesive by weight, the fiber adhesive comprising a mixture of sodium silicate and an acrylic resin, and the adhesive formed by sufficiently agitating the sodium silicate and acrylic resin together to form a homogeneous mixture.
Claim 6
Dependent Claim
81 words
An insulating mixture for spraying onto an object to insulate the object and for thereby building up the insulating mixture on the object to a desired thickness, the insulating mixture comprising about 50% water by weight, about 33% insulating fiber by weight and about 17% fiber adhesive by weight, the fiber adhesive comprising a mixture of sodium silicate and an acrylic resin, and the adhesive formed by sufficiently agitating the sodium silicate and acrylic resin together to form a homogeneous mixture.
Claim 7
Dependent Claim
48 words
A process for preparing an insulating mixture including the steps of providing a container mixing together in the container water, an adhesive including sodium silicate and an acrylic resin, and fiber, wherein the insulating mixture comprises about 50% water, about 33% fiber, and about 17% adhesive by weight.
Claim 8
Dependent Claim
48 words
A process for preparing an insulating mixture including the steps of providing a container mixing together in the container water, an adhesive including sodium silicate and an acrylic resin, and fiber, wherein the insulating mixture comprises about 50% water, about 33% fiber, and about 17% adhesive by weight.
