Thermoelectric device for measuring high temperatures

Claim 1

A THERMOELECTRIC DEVICE FOR MEASURING HIGH TEMPERATURES COMPRISING A PAIR OF PARALLEL DISSIMILAR METAL WIRES, A JUNCTION AT ONE END OF SAID WIRES, A THIN WALLED REFRACTORY SHEATH SURROUNDING THE JUNCTION, A TUBULAR METAL SHEATH SURROUNDING THE TWO DISSIMILAR WIRES FROM A POINT ADJACENT THE END OF THE THIN WALLED REFRACTORY SHEATH TO A POINT BEYOND THE END OF THE TWO DISSIMILAR METALS REMOTE FROM THEIR JUNCTION, INTERLOCKING REFRACTORY SLEEVES EXTENDINGG FROM THE END OF THE METAL SHEATH NEAR THE JUNCTION TO A POINT INTERMEDIATE THE ENDS THEREOF, LOCKING MEANS BETWEEN THE METAL SHEATH AND THE REFRACTORY SLEEVE ADJACENT THE JUNCTION, A THREADED REFRACTORY MEMBER SURROUNDING THE REFRACTORY SHEATH INTERMEDIATE ITS ENDS AND THREADINGLY ENGAGING THE REFRACTORY SLEEVE ADJACENT THE LOCKING MEANS ON THE THIN WALLED REFRACRORY SHEATH FRICTIONALLY ENGAGING SAID THREADED REFRACTORY MEMBER, A METAL SLEEVE SURROUNDING THE TUBULAR SHEATH FIXEDLY-ENGAGING THE REFRACTORY SLEEVE REMOTE FROM THE JUNCTION AND EXTENDING TO A POINT ADJACENT THE END OF THE TUBULAR METAL SHEATH, RESILIENT MEANS FIXED TO THE END OF THE TUBULAR METAL SHEATH ACTING ON THE END OF THE METAL SLEEVE AND COOPERATING WITH THE LOCKING MEANS WHEREBY THE REFRACTORY SLEEVES AND THE METAL SLEEVE ARE MAINTAINED IN SEALING CONTACT UNDER SUBSTANTIALLY CONSTANT PRESSURE A PAIR OF ELECTRICAL LEADS CONNECTED TO THE ENDS OF THE DISSIMILAR WIRES OPPOSITE THE JUNCTION AND EXTENDING OUT OF THE METAL SHEATH TO A CURRENT INDICATING MEANS AND RESILIENT SEALING MEANS BETWEEN THE TUBULAR METAL SHEATH AND THE ELECTRICAL LEADS WHEREBY THE INTERIOR OF THE SHEATH IS SEALED AGAINST PENETRATION OF ATMOSPHERIC GASES.
