Abstract
Abstract A low heat conductant structural support has a series of concentric and spaced tubular columns to thermally insulate and support a load above a base. The outer tubular column is vertically mounted on and may be thermally insulated from the base while the supported load is supported on and may be thermally insulated from the upper rim of the inner column. Intermediate columns join the upper rim of the outer column to the lower rim of the inner column. The columns of the support can be composed of materials such that the over-all thermal contraction of the intermediate columns is equal to the sum of the thermal contraction of the inner and outer columns so that, consequently, the over-all height of the support and correspondingly the distance between the supported load and the base is the same after the temperature has been decreased.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
117 words
A low heat conductant structural support wherein: a. an outer tubular column is vertically mounted on a base; b. an intermediate tubular column is concentrically disposed within and spaced from said outer column, said intermediate column and said outer column being joined together about the circumference of the upper rims of said two columns; c. an inner tubular column is concentrically disposed within and spaced from said intermediate column, said inner column and said intermediate column being joined together about the circumference of the lower rims of said two columns; and d. a supported load is attached to the upper rim of said inner column, whereby the load is supported above and thermally insulated from said base.
Claim 2
Dependent Claim
117 words
A low heat conductant structural support wherein: a. an outer tubular column is vertically mounted on a base; b. an intermediate tubular column is concentrically disposed within and spaced from said outer column, said intermediate column and said outer column being joined together about the circumference of the upper rims of said two columns; c. an inner tubular column is concentrically disposed within and spaced from said intermediate column, said inner column and said intermediate column being joined together about the circumference of the lower rims of said two columns; and d. a supported load is attached to the upper rim of said inner column, whereby the load is supported above and thermally insulated from said base.
Claim 3
Dependent Claim
69 words
The structural support of claim 1 wherein the support is temperature stabilized in that the columns are composed of materials such that the thermal contraction of the intermediate column is equal to the sum of the thermal contractions of the inner and outer columns whereby the over-all height of the support and correspondingly the distance between the supported load and the base remains constant as the temperature is decreased.
Claim 4
Dependent Claim
33 words
The structural support of claim 2 wherein said base is an outer wall of A superconducting electromagnet and said supported load is a liquid helium chamber containing the coils of the superconducting electromagnet.
Claim 5
Dependent Claim
48 words
The structural support of claim 3 wherein the outer wall of the electromagnet is approximately at room temperature, the liquid helium chamber is at approximately 4*K., and the joint between the outer and intermediate columns is thermally sinked to a liquid nitrogen cooled radiation shield at about 78*K.
Claim 6
Dependent Claim
29 words
The structural support of claim 4 wherein the intermediate column is made of aluminum and both the inner and outer columns are made of epoxy fiberglass cloth laminated tubes.
Claim 7
Dependent Claim
177 words
A low heat conductant structural support comprising: an outside tubular column vertically mounted on a base; an odd number of intermediate tubular columns concentrically disposed within and spaced from said outside column and spaced from each other; the outermost intermediate column and said outside column being joined together about the circumference of the upper rims of said two columns; an inside tubular column concentrically disposed within and spaced from the innermost intermediate column, said inside column and said innermost intermediate column being joined together about the circumference of the lower rims of said two columns; each of said intermediate columns being joined about the circumference of the rim on one end to the immediately outer column about the circumference of the rim on its corresponding end and being joined about the circumference of the rim on the opposite end to the immediately inner column about the circumference of the rim on its corresponding end; the supported load being attached to the upper rim of said inside column and thereby supported above and thermally insulated from said base.
Claim 8
Dependent Claim
177 words
A low heat conductant structural support comprising: an outside tubular column vertically mounted on a base; an odd number of intermediate tubular columns concentrically disposed within and spaced from said outside column and spaced from each other; the outermost intermediate column and said outside column being joined together about the circumference of the upper rims of said two columns; an inside tubular column concentrically disposed within and spaced from the innermost intermediate column, said inside column and said innermost intermediate column being joined together about the circumference of the lower rims of said two columns; each of said intermediate columns being joined about the circumference of the rim on one end to the immediately outer column about the circumference of the rim on its corresponding end and being joined about the circumference of the rim on the opposite end to the immediately inner column about the circumference of the rim on its corresponding end; the supported load being attached to the upper rim of said inside column and thereby supported above and thermally insulated from said base.
Claim 9
Dependent Claim
84 words
The structural support of claim 6 wherein the support is temperature stabilized in that the columns are composed of materials such that the resultant thermal contraction of the over-all height of the intermediate columns due to the collective thermal contractions of all intermediate columns is equal to the sum of the thermal contractions of the inside and outside columns whereby the over-all height of the support and correspondingly the distance between the supported load and the base remains constant as the temperature is decreased.
