Abstract
Abstract A support which can be assembled and disassembled at room temperature and events translational and rotational motion at temperatures below room temperature. A truncated cone is located between an outer support housing and an inner housing which is to be supported. The narrow end of the cone is sized to fit over the inner housing and the wide end of the cone is sized to fit within the outer support housing. The cone is comprised of a material which has a higher thermal expansion coefficient than the inner housing.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
139 words
A support apparatus which can be assembled and disassembled at a given temperature and which prevents rotational and translation motion at temperatures below the given temperature comprising: a. a housing to be supported; b. tapered support means having a narrow end and a wide end, and having a coefficient of thermal expansion which is greater than said housing; c. an outer support means; d. said narrow end of said tapered support means shaped to fit loosely around said housing; and e. said wide end of said tapered support means secured to the outer support means, whereby responsive to said apparatus being exposed to temperatures below said given temperature the coefficient of thermal expansion of said tapered support means causes contraction thereof to provide a radial interference fit between said narrow end of said tapered support means and said housing.
Claim 2
Dependent Claim
139 words
A support apparatus which can be assembled and disassembled at a given temperature and which prevents rotational and translation motion at temperatures below the given temperature comprising: a. a housing to be supported; b. tapered support means having a narrow end and a wide end, and having a coefficient of thermal expansion which is greater than said housing; c. an outer support means; d. said narrow end of said tapered support means shaped to fit loosely around said housing; and e. said wide end of said tapered support means secured to the outer support means, whereby responsive to said apparatus being exposed to temperatures below said given temperature the coefficient of thermal expansion of said tapered support means causes contraction thereof to provide a radial interference fit between said narrow end of said tapered support means and said housing.
