Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
141 words
IN THE MELTHOD OF PREPARING A THERMOELECTRIC DEVICE THE STEP COMPRISING COMPACTING UNDER PRESSURE A QUANTITY OF AN ELECTRICALLY AND THERMALLY INSULATING MATERIAL INTO A COMPACT OF A DESIRED DENSITY AND HAVING UPPER AND LOWER SUBSTANTIALLY FLAT END SURFACES, A PLURALITY OF PERFORATIONS EXTENDING BETWEEN THE UPPER AND LOWER END SURFACES AND A PLURALITY OF INTERCONNECTING INDENTATIONS IN AT LEAST ONE OF THE END SURFACES DISPOSED BETWEEN PAIRS OF PERFORATIONS, PLACING A QUANTITY OF COMPACTIBLE THERMOELECTRIC MATERIAL IN EACH OF THE PERFORATIONS IN THE COMPACT AND AN ELECTRICALLY CONDUCTIVE MATERIAL IN THE INTERCONNECTING INDENTATIONS, COMPRISING THE APPLIED THEREMOELECTRIC MATERIAL TO FILL THE PERFORATIONS SO AS TO PROVIDE A HIGH DENSITY THERMOELECTRIC MEMBER IN EACH PERFORATION, AND ALSO COMPRESSING THE ELECTRICALLY CONDUCTIVE MATERIAL IN THE INDENTATIONS SO AS TO PROVIDE AN ELECTRICAL CONDUCTOR BETWEEN THE COMPACTED THERMOELECTRIC MATERIAL FILLING THE PAIRED PERFORATIONS.

Claim 3
Dependent Claim
93 words
A SINTERED THERMOELECTRIC DEVICE COMPRISING A SHAPED BODY OF COMPACTED ELECTRICALLY AND THERMALLY INSULTING MATERIAL HAVING A PLURALITY OF PERFORATIONS EXTENDING BETWEEN THE UPPER AND LOWER END SURFACES OF THE BODY, A PLURALITY OF THERMOELECTRIC MEMBERS COMPRISING MATERIAL COMPACTED WITHIN THE PERFORATIONS SO AS TO CONFORM INTIMATELY TO THE WALLS OF THE PERFORATION AND BEING SUPPORTED THEREBY, SAID MATERIAL HAVING BEEN COMPACTED WHILE IN THE PERFORATION, AND ELECTRICALLY CONDUCTIVE MATERIALS CONTACTING ENDS OF PAIRS OF THERMOELECTRIC MEMBERS AND BEING FLUSH WITH THE END SURFACES OF THE BODY TO PROVIDE A THERMOELECTRIC CONDUCTOR THEREBETWEEN.
