High temperature measuring probe

Claim 1

IN A DEVICE FOR MEASURING HIGH TEMPERATURES, THE COMBINATION COMPRISING A TUBE MADE OF A REFRACTORY CERAMIC MATERIAL, SIAD TUBE HAVING FIRST AND SECOND END PORTIONS, SUPPORTING MEANS AFFORDING SUPPORT FOR SAID FIRST AND SECOND END PORTIONS, A FIRST ELECTRICALLY CONDUCTIVE LEAD EXTENDING INSIDE SAID FIRST END PORTION OF SAID CERAMIC TUBE FROM ONE END THEREOF TO A FIRST POINT THEREALONG AND ANCHORED SECURELY TO SAID CERAMIC TUBE AT SAID FIRST POINT, A SECOND ELECTRICALLY CONDUCTIVE LEAD EXTENDING INSIDE SAID SECOND END PORTION OF SAID TUBE FROM THE OPPOSITE END THEREOF TO A SECOND POINT THEREALONG AND ANCHORED SECURELY TO SAID CERAMIC TUBE AT SAID SECOND PINT, SAID SECOND POINT BEING SPACED ALONG SAID SECOND TUBE FROM SAID FIRST POINT, THE PORTION OF SAID TUBE BETWEEN SAID FIRST AND SECOND POINTS BEING ENTRIELY FREE OF ELECTRICALLY CONDUCTIVE MATERIAL OTHER THAN THE CERAMIC MATERIAL OF SAID TUBE, THE CERAMIC MATERIAL OF SAID TUBE BETWEEN SAID FIRST AND SECOND POINTS THEREBY CONSTITUTING THE SOLE MEANS OF ELECTRICAL CONDUCTION BETWEEN SAID FIRST AND SECOND POINTS AND AFFORDING ELECTRICAL RESISTANCE WHICH VARIES AS A FUNCTION OF TEMPERATURE AT HIGH TEMPERATURES, SAID FIRST AND SECOND END PORTIONS OF SAID TUBE PROVIDING SUPPORT FOR THE PORTION OF SAID CERAMIC TUBE BETWEEN SAID FIRST AND SECOND POINTS AND ALSO HEAT SHIELDING FOR SAID FIRST AND SECOND ELECTRICALLY CONDUCTIVE LEADS.
