Abstract
Abstract A heat transferring device adapted for use in a thermoelectric generator which automatically compensates for shock, vibration, and thermal expansion is disclosed. The device consists of a relatively solid block composed of four slideably moveable wedges arranged in opposing pairs so that the movement of one pair of wedges together causes the other pair of wedges to move apart, one pair of opposing wedges being provided with means biasing them together.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
71 words
A thermal block made from a heat-conducting material comprising four wedges, said wedges arranged in alternating pairs of opposing wedges, the wedges in one alternating pair being biased towards each other, the wedges being further adapted so that adjacent wedges are slideably moveable on their adjacent surfaces, said pairs adapted so that movement of the wedges of one pair together causes a movement apart of the wedges of the other pair.
Claim 2
Dependent Claim
71 words
A thermal block made from a heat-conducting material comprising four wedges, said wedges arranged in alternating pairs of opposing wedges, the wedges in one alternating pair being biased towards each other, the wedges being further adapted so that adjacent wedges are slideably moveable on their adjacent surfaces, said pairs adapted so that movement of the wedges of one pair together causes a movement apart of the wedges of the other pair.
Claim 3
Dependent Claim
14 words
A thermal block as in claim 1, wherein said wedges have a trapezoidal cross-section.
Claim 4
Dependent Claim
16 words
A thermal block as in claim 2, wherein the cross-sections of each wedge are substantially congruent.
Claim 5
Dependent Claim
36 words
A thermal block as in claim 1, wherein each wedge of one pair of opposing wedges has a hole therein, said holes adapted to receive a common bolt when said wedges are assembled in the block.
Claim 6
Dependent Claim
22 words
A thermal block as in claim 1, wherein a layer of thermal grease is located between adjacent sliding surfaces of each wedge.
