Abstract
Abstract A microgeometric electric field machine includes arrays of conductors formed on or carried by a plurality of substrates. The conductors on a first group of substrates carry electrical charges, with alternate conductors being charged positively and the other conductors being charged negatively. A second group of substrates are interleaved with the first group in close proximity therewith. Also included is a voltage source for successively supplying alternate positive and negative electrical charges to the conductors of the second group of substrates. Effectively a pattern of alternate positively and negatively charged conductors is established for the second group of substrates and these patterns are caused to move, relative to the substrates, along the arrays of conductors to produce "moving" electric force fields which cause one group of substrates to move with respect to the other group. The substrates maybe in the form of stacked discs with the conductors being radially positioned thereon, where one group of discs is caused to rotate with respect to another group. Alternatively, the substrates may be in the form of stacked planes with the conductors positioned in parallel thereon, where one group of planes is caused to move linearly with respect to the other group, and in a direction perpendicular to the conductors. the configuration of the substrates, positioning of the conductors, and interleaving of the substrates and conductors could take a variety of forms.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
142 words
An electric field machine comprising a first plurality of elongate, generally parallel elements capable of being charged with an electrical charge and arranged in a multiplicity of planes stacked one above another in a spaced-apart relationship, a second plurality of elongate, generally parallel elements capable of being charged with an electrical charge and arranged in a multiplicity of planes interleaved among the planes of the first plurality, generally parallel therewith and movable in a direction parallel with the planes, either the first or second plurality of elements being electrically charged, with certain elements being charged negatively and other elements, interspersed among the certain elements, being charged positively, and means for successively applying electrical charges to the other plurality of elements to produce electrical force fields which cause the second plurality of elements to move with respect to the first plurality of elements.
Claim 2
Dependent Claim
142 words
An electric field machine comprising a first plurality of elongate, generally parallel elements capable of being charged with an electrical charge and arranged in a multiplicity of planes stacked one above another in a spaced-apart relationship, a second plurality of elongate, generally parallel elements capable of being charged with an electrical charge and arranged in a multiplicity of planes interleaved among the planes of the first plurality, generally parallel therewith and movable in a direction parallel with the planes, either the first or second plurality of elements being electrically charged, with certain elements being charged negatively and other elements, interspersed among the certain elements, being charged positively, and means for successively applying electrical charges to the other plurality of elements to produce electrical force fields which cause the second plurality of elements to move with respect to the first plurality of elements.
Claim 3
Dependent Claim
91 words
An electric field machine as in claim 1 wherein for each pair of adjacent planes, alternate elements of one of the planes are charged positively with the other elements of that plane being charged negatively, and wherein said electrical charge applying means includes means for applying alternate positive and negative charges to successive ones of the elements of the other plane to thereby propagate and move the pattern of positive and negative charges along the array of elements of the other plane and thus cause the one plane to move therewith.
Claim 4
Dependent Claim
65 words
An electric field machine as in claim 2 wherein the spacing of elements in said one plane is two or more times the spacing of elements in said other plane, and wherein the alternate positive and negative charges applied to and moved along the array of elements in said other plane are spaced substantially the same as the spacing of elements in said one plane.
Claim 5
Dependent Claim
49 words
An electric field machine as in claim 1 wherein said elements are from about 200 to 5000 angstroms in width, wherein the spacing of elements of said other plane is from about 200 to 5000 angstroms, and wherein the spacing between planes is from about 200 to 5000 angstroms.
Claim 6
Dependent Claim
156 words
An electric field machine comprising a first plurality of generally planar, parallel substrates stacked one above another in a spaced-apart relationship, a first multiplicity of generally elongate, spaced-apart, parallel conductors carried by the first substrates, a second plurality of generally planar, parallel substrates stacked one above another and interleaved with the first plurality of substrates to be generally parallel therewith, said second substrates being movable in a reciprocating manner, in a direction parallel with the first substrates, a second multiplicity of generally elongate, spaced-apart, parallel conductors carried by the second substrates, wherein alternate ones of the first conductors are charged positively, with the remaining first conductors being charged negatively, and means for applying alternate positive and negative charges to successive ones of the second conductors to thereby propagate and move the pattern of positive and negative charges along the second conductors and thus cause the second substrates to move linearly with respect to the first substrates.
Claim 7
Dependent Claim
156 words
An electric field machine comprising a first plurality of generally planar, parallel substrates stacked one above another in a spaced-apart relationship, a first multiplicity of generally elongate, spaced-apart, parallel conductors carried by the first substrates, a second plurality of generally planar, parallel substrates stacked one above another and interleaved with the first plurality of substrates to be generally parallel therewith, said second substrates being movable in a reciprocating manner, in a direction parallel with the first substrates, a second multiplicity of generally elongate, spaced-apart, parallel conductors carried by the second substrates, wherein alternate ones of the first conductors are charged positively, with the remaining first conductors being charged negatively, and means for applying alternate positive and negative charges to successive ones of the second conductors to thereby propagate and move the pattern of positive and negative charges along the second conductors and thus cause the second substrates to move linearly with respect to the first substrates.
Claim 8
Dependent Claim
60 words
An electric field machine as in claim 5 wherein the spacing of the first conductors from one another is two or more times the spacing of the second conductors from one another, and wherein the alternate positive and negative charges applied to and moved along the second conductors are spaced substantially the same as the spacing of the first conductors.
