Abstract
Abstract An electric furnace roof or other generally circular structure is formed by concentric rows of bricks disposed side by side in each row. Each brick is the same size throughout the entire structure or individual sections thereof and is tapered to present a pair of opposed, non-parallel sides, the single size being determined in accordance with the innermost radius of the inner row to permit such radius, or a preselected smaller radius, to be turned by bricks oriented in the regular position with the larger width across the taper at the outer periphery of the row. In order to turn the greater radii of the remaining, outer rows, certain of the bricks in each row are reversed to place the larger width at the inner periphery of the respective row. The number of reversed brick in each row is determined mathematically by initially assuming the existence of imaginary reversed bricks expanded in size to equalize the widths of all bricks, both real and imaginary, of a given row at the outer periphery thereof. A digital computer is programmed to provide output including the numbers of brick or each row in both regular and reversed positions, from input comprising design dimensions and conditions of the structure to be built.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
193 words
A generally circular composite structure, such as an electric furnace roof or the like, comprising: means for presenting a generally circular, central portion of said structure; a plurality of tapered structural elements of a single shape and size, each of said elements having a tapered top, a tapered bottom, a wide end, a narrow end, and a pair of opposed sides converging toward each other from said wide end toward said nArrow end, said elements being arranged in a plurality of generally annular rows having a common central axis, including an innermost row and at least one outer row, with said sides of each element facing toward the sides of the adjacent elements in the same row, at least certain of said elements in each row being regularly oriented with said narrow ends thereof facing inwardly toward said central portion, there being other of said elements in each outer row that are reversely oriented with said wide ends thereof facing inwardly toward said central portion, defining a generally annular, outer main portion of said structure around said central portion thereof; and support means for holding said elements in said arrangement and orientations thereof.
Claim 2
Dependent Claim
193 words
A generally circular composite structure, such as an electric furnace roof or the like, comprising: means for presenting a generally circular, central portion of said structure; a plurality of tapered structural elements of a single shape and size, each of said elements having a tapered top, a tapered bottom, a wide end, a narrow end, and a pair of opposed sides converging toward each other from said wide end toward said nArrow end, said elements being arranged in a plurality of generally annular rows having a common central axis, including an innermost row and at least one outer row, with said sides of each element facing toward the sides of the adjacent elements in the same row, at least certain of said elements in each row being regularly oriented with said narrow ends thereof facing inwardly toward said central portion, there being other of said elements in each outer row that are reversely oriented with said wide ends thereof facing inwardly toward said central portion, defining a generally annular, outer main portion of said structure around said central portion thereof; and support means for holding said elements in said arrangement and orientations thereof.
Claim 3
Dependent Claim
32 words
A structure as set forth in claim 1, wherein said support means requires no mortar, and includes generally annular means around the outer extremity of and circumferentially confining said outer main portion.
Claim 4
Dependent Claim
28 words
A structure as set forth in claim 1, wherein said reversely oriented elements are interspersed at substantially equal intervals among said regularly oriented elements in each outer row.
Claim 5
Dependent Claim
43 words
A structure as set forth in claim 1, wherein there are a plurality of said rows in the outer main portion, and the number of said reversely oriented elements per row increases as the outer extremity of said outer main portion is approached.
Claim 6
Dependent Claim
71 words
A structure as set forth in claim 1, wherein the shape and size of said elements, the total number of said elements in all of said rows, the total number of said elements in each row, the number of regularly oriented elements in each outer row, and the number of reversely oriented elements in each outer row are each predetermined by computation prior to assembly thereof in said arrangement and orientation.
Claim 7
Dependent Claim
152 words
A structure as set forth in claim 1, wherein said central portion includes at least one generally sector-shaped portion comprising: a plurality of tapered structural pieces of a single shape and size, each of said pieces having a tapered top, a tapered bottom, a wide end, a narrow end, and a pair of opposed sides converging toward each other from said wide end toward said narrow end, said pieces being arranged in a plurality of generally partially annular rows having a common central axis, including a row adjacent said outer main portion with said sides of each piece facing toward the sides of the adjacent pieces in the same row, at least certain of said pieces in each row thereof being regularly oriented with said narrow ends thereof facing inwardly, there being other pieces in at least said outermost row thereof, that are reversely oriented with said wide ends thereof facing inwardly.
Claim 8
Dependent Claim
23 words
A structure as set forth in claim 6, wherein said elements and said pieces are both of the same, single shape and size.
Claim 9
Dependent Claim
44 words
A structure as set forth in claim 1, wherein said sides and said ends are also tapered and are bounded by edges converging toward each other from said top toward said bottom, whereby said structure has generally spherical curvature to present a dome configuration.
Claim 10
Dependent Claim
136 words
A composite structure comprising: a plurality of tapered structural elements of a single shape and size, each of said elements having a tapered top, a tapered bottom, a wide end, a narrow end, and a pair of opposed sides converging toward each other from said wide end toward said narrow end, said elements being arranged in at least one row having inner and outer edges of substantially circular curvature with said sides of each element facing toward the sides of the adjacent elements, a first plurality of said elements in said one row being regularly oriented with said narrow ends thereof facing inwardly, a second plurality of said elements in said one row being reversely oriented with said wide ends thereof facing inwardly; and support means for holding said elements in said arrangement and orientation thereof.
Claim 11
Dependent Claim
136 words
A composite structure comprising: a plurality of tapered structural elements of a single shape and size, each of said elements having a tapered top, a tapered bottom, a wide end, a narrow end, and a pair of opposed sides converging toward each other from said wide end toward said narrow end, said elements being arranged in at least one row having inner and outer edges of substantially circular curvature with said sides of each element facing toward the sides of the adjacent elements, a first plurality of said elements in said one row being regularly oriented with said narrow ends thereof facing inwardly, a second plurality of said elements in said one row being reversely oriented with said wide ends thereof facing inwardly; and support means for holding said elements in said arrangement and orientation thereof.
Claim 12
Dependent Claim
150 words
A generally annular composite structure comprising: a plurality of tapered structural elements of a single shape and size, each of said elements having a tapered top, a tapered bottom, a wide end, a narrow end, and a pair of opposed sides converging toward each other from said wide end toward said narrow end, said elements being arranged in a plurality of generally annular rows having a common central axis, including an innermost row and at least one outer row, with said sides of each element facing toward the sides of the adjacent elements in the same row, at least certain of said elements in each row being regularly oriented with said narrow ends thereof facing inwardly, there being other of said elements in each outer row that are reversely oriented with said wide ends thereof facing inwardly; and support means for holding said elements in said arrangement and orientations thereof.
