Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
134 words
A THERMOELECTRIC DEVICE COMPRISING, A THERMALLY CONDUCTIVE TUBULAR MEMBER, A FIRST ELECTRICAL CONDUCTOR MEANS HELICALLY DISPOSED ON AN OUTER SURFACE OF SAID TUBULAR MEMBER AND ELECTRICALLY INSULATED THEREFROM, A SECOND ELECTRICAL CONDUCTOR MEANS SPACED RADIALLY OUTWARD FROM SAID FIRST ELECTRICAL CONDUCTOR MEANS AND DISPOSED IN A HELICAL PATH PARALLEL THERETO, AND A PLURALITY OF SPACED APART THERMOELECTRICAL SEMI-CONDUCTOR MEANS DISPOSED BETWEEN SAID FIRST AND SECOND ELECTRICAL CONDUCTOR MEANS TO FORM A HELICAL SERIES ARRAY OF ALTERNATELY CONNECTED THERMOELECTRIC ELEMENTS WHEREIN BOTH SAID ELECTRICAL CONDUCTOR MEANS FROM JUNCTIONS BETWEEN SAID ALTERNATELY CONNECTED THERMOELECTRIC ELEMENTS, SAID THERMO ELECTRIC ELEMENTS ADAPTED TO CO-ACT WITH SAID JUNCTIONS TO RESULT IN A HEAT TRANSFER FROM JUNCTIONS FORMED BY ONE ELECTRICAL CONDUCTOR MEANS TO JUNCTIONS BETWEEN SAID ALTERNATELY ELECTRICAL CONDUCTOR MEANS WHEN A DIRECT ELECTRICAL CURRENT FLOWS THROUGH THE DEVICE.
Claim 2
Dependent Claim

Claim 3
Dependent Claim
119 words
IN A METHOD FOR CONSTRUCTING A THERMOELECTRIC DEVICE THAT CONSISTS OF A PLURAITY OF RADIALLY SPACED-APART DISCRETE ELECTRICAL CONDUCTOR STRIPS POSITIONED AROUND A TUBULAR MEMBER TO FORM A HELICAL SERIES ARRAY OF ALTERNATELY CONNECTED THERMOLELECTRIC ELEMENTS POSITIONED BETWEEN THE CONDUCTOR STRIPS, THE METHOD COMPRISING THE STEPS OF, ADHESIVELY POSITIONING AN ELECTRICAL CONDUCTOR AROUND A TUBULAR MEMBER, SEVERING THE ELECTRICAL CONDUCTOR TO FORM ROWS OF STRIPS, POSITIONING TWO BARS OF DISSIMILAR THERMOELECTRIC SEMICONDUCTOR MATERIAL IN SPACED-APART PARALLEL RELATION ON EACH ROW OF CONDUCTOR STRIPS, POSITIONING ANOTHER ELECTRICAL CONDUCTOR AROUND THE THERMOELECTRICAL BARS, SOLDERING THE THERMOELECTRIC BORS TO THE ELECTRICAL CONDUCTORS, AND CUTTING A HELICAL PATH IN THE AXIAL DIRECTION OF THE TUBULAR MEMBER TO SEVER AT LEAST THE THERMOELECTRIC BARS.
