  • Spacer for coaxial tube systems
    Patent number: 4220179
    Abstract: Spacer for concentrically disposed tube systems where a temperature drop exists between adjacent tubes. This may consist, for example, of a superconducting electric cable or alternatively of a tube system for carrying heated liquid or gaseous media. The concentric tubes are spaced by a winder which touches the surfaces of adjacent tubes at particular points and which consists of two ribbons of insulating material disposed adjacent to each other having two elements in-between, and one of them being wound about the other so that they touch adjacent ribbon surfaces only in isolated points.
    Type: Grant

  • Spacer for coaxial tube systems
    Patent number: 4161966
    Abstract: Spacer for concentrically disposed tube systems where a temperature drop exists between adjacent tubes. This may consist, for example, of a superconducting electric cable or alternatively of a tube system for carrying heated liquid or gaseous media. The concentric tubes are spaced by a winder which touches the surfaces of adjacent tubes at particular points and which consists of ribbons of insulating material disposed adjacent to each other. The individual ribbons are so formed and so arranged that they touch adjacent tube surfaces either at only individual points or at lines.
