Abstract
Abstract A plurality of alternating junctions of two types arranged in a series configuration. The first junction type is comprised of two materials in overlapping arrangement. The second junction type is also comprised of two materials and additionally has a third material therebetween. Current flow through the junction produces a Peltier heating or cooling effect at the first type of junction. Either no thermal effect or both Peltier heating and cooling occur at the second type of junction which cancel out. The effect is the cumulative Peltier effects produced at the first type of junction.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
59 words
A Peltier effect system comprising a group of similar junctions formed between metals, a second group of composite junctions formed between materials such that when current passes therethrough, the Peltier effect cancels, all junctions being connected in series electrically, with junctions of the first and second groups alternating, whereby the Peltier effect of all first group junctions is cumulative.
Claim 2
Dependent Claim
59 words
A Peltier effect system comprising a group of similar junctions formed between metals, a second group of composite junctions formed between materials such that when current passes therethrough, the Peltier effect cancels, all junctions being connected in series electrically, with junctions of the first and second groups alternating, whereby the Peltier effect of all first group junctions is cumulative.
Claim 3
Dependent Claim
50 words
A system in accordance with claim 1, including a first metal and a second metal, wherein said first metal and said second metal are positioned in overlapping relationship to provide a junction of said first group therebetween, whereby current flow in a first direction therethrough produces a first energy effect.
Claim 4
Dependent Claim
43 words
A system in accordance with claim 2, further including a third metal, wherein said third metal is placed on said second metal to form a junction in said second group, whereby current flow in a first direction therethrough produces a predetermined energy effect.
Claim 5
Dependent Claim
64 words
A system in accordance with claim 3, further including a metal similar to said first metal positioned over said third metal and forming a junction therewith in said second group, whereby current flow in a first direction therethrough produces a predetermined energy effect opposing the effect produced by current flow through said second metal and third metal, thereby cancelling the Peltier effect produced thereby.
Claim 6
Dependent Claim
16 words
A materials composition strip in accordance with claim 2, wherein said first metal is typically copper.
Claim 7
Dependent Claim
17 words
A materials composition strip in accordance with claim 2, wherein said second metal is typically stainless steel.
Claim 8
Dependent Claim
16 words
A materials composition strip in accordance with claim 3, wherein said third metal is typically graphite.
Claim 9
Dependent Claim
115 words
A materials composition arrangement for thermoelectric heating and cooling comprising a plurality of a first type of junction, each of said junctions including a first type of material in overlapping relationship and a plurality of a second type of junction, each of said last mentioned junctions including said first and second types of material in overlapping relationship and further including a third material therebetween whereby passage of current through said first type of junction produces a heating effect and passage of current through said second type of junction produces heating and cooling thereby cancelling so that the cumulative effect of the arrangement results from the effect produced by said plurality of first type of junction.
Claim 10
Dependent Claim
115 words
A materials composition arrangement for thermoelectric heating and cooling comprising a plurality of a first type of junction, each of said junctions including a first type of material in overlapping relationship and a plurality of a second type of junction, each of said last mentioned junctions including said first and second types of material in overlapping relationship and further including a third material therebetween whereby passage of current through said first type of junction produces a heating effect and passage of current through said second type of junction produces heating and cooling thereby cancelling so that the cumulative effect of the arrangement results from the effect produced by said plurality of first type of junction.
Claim 11
Dependent Claim
22 words
A materials composition strip in accordance with claim 8, wherein passage of current in the opposite direction permits said strip to cool.
Claim 12
Dependent Claim
52 words
A Peltier effect system comprising a group of similar junctions formed between metals, a second group of composite junctions formed between materials such that when current passes therethrough, no thermal effect occurs, all junctions of the first and second groups alternating, whereby the Peltier effect of all first group junctions is cumulative.
Claim 13
Dependent Claim
52 words
A Peltier effect system comprising a group of similar junctions formed between metals, a second group of composite junctions formed between materials such that when current passes therethrough, no thermal effect occurs, all junctions of the first and second groups alternating, whereby the Peltier effect of all first group junctions is cumulative.
Claim 14
Dependent Claim
50 words
A system in accordance with claim 10, including a first metal and a second metal, wherein said first metal and said second metal are positioned in overlapping relationship to provide a junction of said first group therebetween, thereby current flow in a first direction therethrough produces a first energy effect.
Claim 15
Dependent Claim
43 words
A system in accordance with claim 10, further including a third metal, wherein said third metal is placed on said second metal to form a junction in said second group, whereby current flow in a first direction therethrough produces a predetermined energy effect.
