Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
111 words
A decorative, porous vaulted panel having sound dampening acoustical properties consisting essentially of a composite laminated structure of deep concave configuration composed of a substantially rigid self-supporting body of generally random felted mineral fiber bonded with at least one thermosetting translucent resin selected from the group consisting of melamine formaldehyde, ureaformaldehyde and polyester, and having a facing mat superimposed conterminously with one major surface of the said substantially rigid self-supporting body of felted fiber and adhered thereto, said facing mat being composed of mineral filaments lying generally transverse to each other and impregnated with at least one thermosetting translucent resin selected from the group consisting of melamine formaldehyde, ureaformaldehyde and polyester.
Claim 2
Dependent Claim
111 words
A decorative, porous vaulted panel having sound dampening acoustical properties consisting essentially of a composite laminated structure of deep concave configuration composed of a substantially rigid self-supporting body of generally random felted mineral fiber bonded with at least one thermosetting translucent resin selected from the group consisting of melamine formaldehyde, ureaformaldehyde and polyester, and having a facing mat superimposed conterminously with one major surface of the said substantially rigid self-supporting body of felted fiber and adhered thereto, said facing mat being composed of mineral filaments lying generally transverse to each other and impregnated with at least one thermosetting translucent resin selected from the group consisting of melamine formaldehyde, ureaformaldehyde and polyester.
Claim 3
Dependent Claim
60 words
The porous acoustical vaulted panel product of claim 1, wherein the facing mat superimposed conterminously with and adhered to the said rigid body of felted mineral fibers is impregnated with a combination of translucent resin and pigment in a ratio of about 30 to 100 percent by weight of resin to about 0 to 70 percent by weight of pigment.
Claim 4
Dependent Claim
38 words
The porous acoustical vaulted panel product of claim 2, wherein the said impregnating composition of the facing mat comprises approximately 30 to 50 percent by weight of resin and approximately 0 to 70 percent by weight of pigments.
Claim 5
Dependent Claim
32 words
The porous acoustical vAulted panel product of claim 2, wherein the pigment comprises at least one white pigment selected from the group consisting of titanium dioxide, zinc oxide, white lead, and clay.
Claim 6
Dependent Claim
29 words
The porous acoustical vaulted panel product of claim 4, wherein the thermosetting resin bond for the substantially rigid body of generally random felted mineral fiber is melamine formaldehyde resin.
Claim 7
Dependent Claim
33 words
The porous acoustical vaulted panel product of claim 5, wherein the thermosetting resin of the impregnate for the facing mat of mineral filaments lying generally transverse to each other is melamine formaldehyde resin.
Claim 8
Dependent Claim
16 words
The porous acoustical vaulted panel product of claim 6, wherein the white pigment is titanium dioxide.
Claim 9
Dependent Claim
36 words
The porous acoustical vaulted panel product of claim 7, wherein the impregnating combination for the facing mat comprises approximately 40 percent by weight of the resin and approximately 60 percent by weight of the white pigment.
Claim 10
Dependent Claim
23 words
The porous acoustical vaulted panel product of claim 8, having a porous coating of paint on the exposed surface of the facing mat.
Claim 11
Dependent Claim
26 words
The porous acoustical vaulted panel product of claim 9, wherein the facing mat of mineral filaments lying generally transverse to each other in a nonwoven fabric.
Claim 12
Dependent Claim
40 words
The porous acoustical vaulted panel product of claim 10, wherein the nonwoven fabric facing mat of mineral filaments lying generally transverse to each other is an open scrim having a weight of approximately 2 to 3 grams per square foot.
Claim 13
Dependent Claim
48 words
The porous acoustical vaulted panel product of claim 1, wherein the substantially rigid body of generally random felted mineral fiber bonded with thermosetting resin is composed of a plurality of sections with at least the section adjacent to the facing mat being bonded with a thermosetting translucent resin.
