Claims Analysis

Total Claims: 9
Claim 1
Independent Claim 239 words
Apparatus for generating electric energy from heat energy comprising: (a) a first electrode means, (b) a second electrode means spaced proximate said first electrode means such that a first dielectric region is established therebetween, (c) means for initially charging said first and second electrode means, (d) means for electrically disconnecting said first electrode means from said means for initially charging said first and second electrode means, (e) means for decreasing the capacitance between said first and second electrode means after said first electrode means has been electrically disconnected from said charging means, (f) means for electrically connecting said first and second electrode means in circuit with a load to be driven which is desired to be driven, (g) said means for decreasing the capacitance between said first and second electrode means further comprising means for magnetically forcing said first electrode to move with respect to said second electrode such that the distance between said first and second electrode means is increased, (h) said magnetic forcing means further comprising a magnetic field producing means, a ferromagnetic material positioned substantially within the magnetic field produced by said magnetic field producing means and a means whereby said ferromagnetic material may be caused to increase and decrease in temperature such that the magnetic permeability of said ferromagnetic material is made to vary in strength thereby causing the magnetic field in the space proximate said ferromagnetic material to be made to vary in strength.
Claim 2
Dependent Claim 239 words
Apparatus for generating electric energy from heat energy comprising: (a) a first electrode means, (b) a second electrode means spaced proximate said first electrode means such that a first dielectric region is established therebetween, (c) means for initially charging said first and second electrode means, (d) means for electrically disconnecting said first electrode means from said means for initially charging said first and second electrode means, (e) means for decreasing the capacitance between said first and second electrode means after said first electrode means has been electrically disconnected from said charging means, (f) means for electrically connecting said first and second electrode means in circuit with a load to be driven which is desired to be driven, (g) said means for decreasing the capacitance between said first and second electrode means further comprising means for magnetically forcing said first electrode to move with respect to said second electrode such that the distance between said first and second electrode means is increased, (h) said magnetic forcing means further comprising a magnetic field producing means, a ferromagnetic material positioned substantially within the magnetic field produced by said magnetic field producing means and a means whereby said ferromagnetic material may be caused to increase and decrease in temperature such that the magnetic permeability of said ferromagnetic material is made to vary in strength thereby causing the magnetic field in the space proximate said ferromagnetic material to be made to vary in strength.
