Application of differential thermal contraction to obtain improved cryogenic interfacial contact - A simplified explanation of the abstract

This abstract first appeared for US patent application 17644443 titled 'Application of differential thermal contraction to obtain improved cryogenic interfacial contact

Simplified Explanation

The patent application describes an apparatus that consists of two components made of different materials with different thermal contraction properties. The second component has an opening where a part of the first component is inserted at room temperature.

  • The second component has a larger thermal contraction property than the first component.
  • When the apparatus is exposed to cryogenic temperatures, both components contract.
  • The second component constricts more than the first component, exerting a constricting force on the inserted portion of the first component.

Potential applications of this technology:

  • Cryogenic engineering
  • Thermal expansion compensation in various systems
  • Precision instruments and devices operating at low temperatures

Problems solved by this technology:

  • Addressing thermal expansion mismatch between different components
  • Ensuring tight and secure connections in cryogenic environments

Benefits of this technology:

  • Improved stability and reliability of systems operating at cryogenic temperatures
  • Enhanced precision and accuracy in measurements and experiments conducted at low temperatures


Original Abstract Submitted

An apparatus comprising a first component comprised of a first material, wherein the first material has a first thermal contraction property. A second component comprised of a second material, wherein the second material has a second thermal contraction property, wherein the second component has an opening where a portion of the first component is inserted into at room temperature. Wherein the second thermal contraction property is larger than the first thermal contraction property and when at cryogenic temperatures, the first component and second component constrict, wherein the second component constricts more than the first component causing the second component to exert a constricting force on the portion of the first component inserted into the opening of the second component.
