Abstract
Abstract Method for moving moisture in moisture bearing material by disposing the material in an electrostatic field comprising a plurality of non-uniform electrostatic fields with each field having the higher intensity portion thereof substantially oppositely located relative to the higher intensity portion of an adjacent non-uniform field and at least partially extending across the material to act on at least part of the moisture thereof to move at least part of the moisture relative to the material.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
79 words
A method of treating moisture bearing material comprising the steps of creating a plurality of non-uniform electrostatic fields with each field having the higher intensity portion thereof substantially oppositely located relative to the higher intensity portion of an adjacent non-uniform field, and disposing said material so that said non-uniform fields at least partially extend across said material to act on at least part of the moisture thereof to move at least part of said moisture relative to said material.
Claim 2
Independent Claim
79 words
A method of treating moisture bearing material comprising the steps of creating a plurality of non-uniform electrostatic fields with each field having the higher intensity portion thereof substantially oppositely located relative to the higher intensity portion of an adjacent non-uniform field, and disposing said material so that said non-uniform fields at least partially extend across said material to act on at least part of the moisture thereof to move at least part of said moisture relative to said material.
Claim 3
Dependent Claim
22 words
A method as set forth in claim 1 and including the step of causing relative movement between said material and said fields.
Claim 4
Dependent Claim
42 words
A method as set forth in claim 1 wherein said step of creating said non-uniform electrostatic fields comprises the step of disposing a plurality of pairs of spaced apart electrodes with each pair of electrodes creating one of said non-uniform fields therebetween.
Claim 5
Dependent Claim
25 words
A method as set forth in claim 3 and including the step of electrically insulating said electrodes from said moisture of said moisture bearing material.
Claim 6
Dependent Claim
19 words
A method as set forth in claim 3 and including the step of forming said electrodes from electret means.
Claim 7
Dependent Claim
34 words
A method as set forth in claim 1 wherein said step of disposing said material comprises the step of supporting said material so that said non-uniform fields at least partially extend across said material.
Claim 8
Dependent Claim
44 words
A method as set forth in claim 3 wherein said step of disposing said material comprises the step of disposing said material so as to be out of contact with said electrodes while said non-uniform fields still at least partially extend across said material.
Claim 9
Dependent Claim
22 words
A method as set forth in claim 7 and including the step of causing relative movement between said material and said fields.
Claim 10
Dependent Claim
43 words
A method as set forth in claim 3 wherein said step of disposing said material comprises the step of disposing said material so as to be in contact with said electrodes while said non-uniform fields still at least partially extend across said material.
Claim 11
Dependent Claim
22 words
A method as set forth in claim 9 and including the step of causing simultaneous movement of said fields and said material.
