Claims Analysis

Total Claims: 14
Claim 1
Independent Claim 76 words
In combination with an internal combustion engine having an electrical system and a battery having a negative and a positive terminal connected to the engine electrical system, an energy efficiency device comprising: a pair of closely adjacent electrically conductive coils disposed on substantially parallel axes; means for mounting said coils adjacent one terminal of the battery; and a wire having one end adjacent said coils and its other end electrically connected to the other battery terminal.
Claim 2
Dependent Claim 76 words
In combination with an internal combustion engine having an electrical system and a battery having a negative and a positive terminal connected to the engine electrical system, an energy efficiency device comprising: a pair of closely adjacent electrically conductive coils disposed on substantially parallel axes; means for mounting said coils adjacent one terminal of the battery; and a wire having one end adjacent said coils and its other end electrically connected to the other battery terminal.
Claim 3
Dependent Claim 16 words
The invention as defined in claim 1 wherein the ends of the coils are connected together.
Claim 4
Dependent Claim 16 words
The invention as defined in claim 1 and including an iron core disposed through each coil.
Claim 5
Dependent Claim 21 words
The invention as defined in claim 1 wherein one coil has substantially three times as many windings as the other coil.
Claim 6
Dependent Claim 18 words
The invention as defined in claim 2 wherein said wire is electrically connected to at least one coil.
Claim 7
Dependent Claim 18 words
The invention as defined in claim 3 wherein said wire is connected to at least one iron core.
Claim 8
Dependent Claim 25 words
The invention as defined in claim 6 wherein said core is U-shaped with one coil being wound about each free leg of the U-shaped core.
Claim 9
Dependent Claim 17 words
The invention as defined in claim 1 wherein said coils are encapsulated in an electrically insulating material.
Claim 10
Dependent Claim 22 words
The invention as defined in claim 1 wherein said battery has a housing and wherein said wire is molded into said housing.
Claim 11
Dependent Claim 81 words
The invention as defined in claim 1 wherein each battery terminal is connected to the engine electrical system via a battery cable, said device further comprising a first iron wire extending outwardly from the positive terminal battery cable and secured at its free end to the front of the engine and a second iron wire extending outwardly from the negative terminal battery cable and connected to the rear of the engine, said iron wires being electrically insulated from the battery cables.
Claim 12
Dependent Claim 91 words
The invention as defined in claim 1 wherein each battery terminal is connected to the engine electrical system via a battery cable, said device further comprising a first iron wire extending outwardly from the negative terminal battery cable and connected at its free end to the rear of the engine and a second iron wire extending outwardly from the positive terminal battery cable and connected at its free end to one terminal of a switch means, the other terminal of the switch being electrically connected to the front of the engine.
Claim 13
Dependent Claim 19 words
The invention as defined in claim 11 wherein said switch means is a normally open manifold vacuum actuated switch.
Claim 14
Dependent Claim 14 words
The invention as defined in claim 1 wherein said wire is made of iron.
