1. A thermally insulated cryogenic coupler including:
- a section of inner piping having a first and second end;
a section of outer piping having a first and second end, the first and second ends substantially coterminous with the first and second ends of the said section of inner piping, wherein the internal diameter of said outer section of piping is larger than the outer diameter of said inner section of piping, said section of inner piping positioned within said section of outer piping;
the said sections of said inner and outer piping joined one to the other at their first and second ends to define a closed, hermetically sealed annular space between said inner and outer sections of piping;
whereby,a condition of vacuum is provided and maintained between the inner and outer sections of said piping.

11. In a cryogenic fluid delivery system, a connecting assembly having a first section of insulated transport pipe, including an internal receiving sleeve, and a second section of insulated transport pipe including an internal receiving sleeve, each of said first and second sections of insulated pipe terminating in a flanged end section, and means for coupling the two said pipe sections together at their flanged ends, the improvement comprising:
a jacketed piping insert, said piping insert comprising a section of pipe including an inner pipe and an outer pipe, the inner pipe spaced from the outer pipe to define an annular space between them, said jacketed piping insert vacuum sealed to define a vacuum within said annular space, the jacketed piping insert having a diameter sized so as to be received by each of said receiving sleeves of said sections of insulated pipe. - View Dependent Claims (12)
