Abstract
Abstract A matrix disk for a rotary regenerator is made up of spiral turns of a first strip having spaced apart corrugations all orientated in the same direction inclined at an angle to the face of the disk and a second strip having spaced apart corrugations all orientated in the same direction inclined at an angle to the face of the disk in the opposite direction from that of the corrugations of the first strip.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
254 words
A rotary regenerator matrix structure of annular form porous to flow of fluid generally parallel to the axis of the matrix and effective to block fluid flow circumferentially around the axis, the matrix structure comprising first and second spiral wound strips with each turn of the first strip disposed between adjacent turns of the second strip and with the strips abutting face to face and fixed together into a rigid, elastic structure, the first strip being provided with spaced apart corrugations inclined at a relatively small angle of approximately 1/2 * to 4* in one direction relative to the axis of the matrix, the portion of said first strip between said spaced apart corrugations thereon being substantially flat sheet stock material, the second strip being formed with spaced apart corrugations inclined in the opposite direction and at an equivalent angle to the axis of the matrix from the corrugations of the first strip, the portion of said second strip between said spaced apart corrugations thereon being substantially flat sheet stock material, the corrugations of the first strip and of the second strip having substantial depth radially of the matrix to separate radially the turns of the other strip, the corrugations extending from one side only of each said strip, the opposite side of each said strip presenting substantially a flat surface against which the peaks of said corrugations of the adjacent strip abut to define substantially rectangular fluid flow passages between adjacent strips, the circumferential extent of said passages being defined by said corrugations.

Dependent Claim

Claim 3
Dependent Claim
258 words
A rotary regenerator matrix structure of annular form porous to flow of fluid generally parallel to the axis of the matrix and effective to block fluid flow circumferentially around the axis, the matrix structure comprising first and second spiral wound strips with each turn of the first strip disposed between adjacent turns of the second strip and with the strips abutting face to face and fixed together into a rigid, elastic structure, the first strip being provided with corrugations at spaced apart intervals separated by substantially flat sheet strip portions, said corrugations being inclined in one direction relative to the axis of the matrix at an angle of approximately 1/2 * to 4* to the axis of the matrix, the second strip being formed with corrugations at spaced apart intervals separated by substantially flat sheet strip portions, said corrugations of said second strip being inclined in the opposite direction to the axis of the matrix from the corrugations of the first strip and at the same angle, the corrugations of the first strip and of the second strip having a rib heighth radially of the matrix of from 0.012 inch to 0.025 inch to separate radially the turns of the other strip, the corrugations extending from one side only of each said strip, the opposite side of each said strip presenting substantially a flat surface against which the peaks of said corrugations of the adjacent strip abut to define substantially rectangular fluid flow passages between adjacent strips, the circumferential extent of said passages being defined by said corrugations.
Claim 4
Dependent Claim
258 words
A rotary regenerator matrix structure of annular form porous to flow of fluid generally parallel to the axis of the matrix and effective to block fluid flow circumferentially around the axis, the matrix structure comprising first and second spiral wound strips with each turn of the first strip disposed between adjacent turns of the second strip and with the strips abutting face to face and fixed together into a rigid, elastic structure, the first strip being provided with corrugations at spaced apart intervals separated by substantially flat sheet strip portions, said corrugations being inclined in one direction relative to the axis of the matrix at an angle of approximately 1/2 * to 4* to the axis of the matrix, the second strip being formed with corrugations at spaced apart intervals separated by substantially flat sheet strip portions, said corrugations of said second strip being inclined in the opposite direction to the axis of the matrix from the corrugations of the first strip and at the same angle, the corrugations of the first strip and of the second strip having a rib heighth radially of the matrix of from 0.012 inch to 0.025 inch to separate radially the turns of the other strip, the corrugations extending from one side only of each said strip, the opposite side of each said strip presenting substantially a flat surface against which the peaks of said corrugations of the adjacent strip abut to define substantially rectangular fluid flow passages between adjacent strips, the circumferential extent of said passages being defined by said corrugations.
Claim 5
Dependent Claim
30 words
A rotary regenerator matrix structure according to claim 2 wherein the spacing of said corrugations on said first strip and said second strip is between 0.050 inch to 0.150 inch.
