Thermocouple split follower

A radioisotope heated thermoelectric generator assembly, comprising a cold frame forming holes therein, a plurality of thermocouples having first and second ends, said first ends having a hot frame connected thereto and said second ends having a hemispherical shape forming a slot therein, a cylindrical shaped follower having a first end, a hemispherical second opposite end and opposite wedge shaped fillets on the inside thereof, said follower being split to form symmetrical split follower halves having a longitudinally extending gap therebetween, and resilient means for urging said hemispherical second follower end against said second end of said thermocouple for the urging outside of said follower halves against the inside of said cold frame.

A radioisotope heated thermoelectric generator assembly, comprising a cylindrical shell, an annular cold frame inside said shell forming holes therein at right angles to said shell axis, a plurality of thermocouples having first and second ends, said first ends having a hot frame connected thereto and said second ends having a hemispherical shape forming a slot therein, cylindrical shaped followers having a first end, a hemispherical opposite second end and opposite wedge shaped fillets on the inside thereof adjacent said second follower end, said follower being split to form symmetrical split follower halves having a longitudinally extending gap therebetween equi-distant from said fillets, and resilient means disposed between the inside of said shell and said wedge shaped fillets for urging said second ends of said followers and thermocouples respectively against each other for urging the outside of said followers against the inside of said holes in said cold frame.

A radioisotope heated thermoelectric generator assembly comprising a thermocouple having a first and second ends, said first end having a hot frame connected thereto and said second end having a cold frame connected thereto, said cold frame having two symmetrical split follower halves, means for holding said thermocouple from rotation, and means for relatively rotating said follower halves to hone the folower halves against the second end of said thermocouple.
