Abstract
Abstract This disclosure relates to a laundry apparatus, paper making apparatus or the like wherein the moisture or liquid in the wet laundry, food materials, paper slurry or the like, disposed therein is removed by an electrostatic means that provides a differential in the potential of the moisutre in the laundry, food materials, paper slurry or the like and an electrode means for the moisture to tend to cause the moisture to leave the laundry, food materials, paper slurry or the like and move toward the electrode means. Such electrode means can comprise a suction nozzle which tends to draw a large volume of air through the laundry, food materials, paper slurry or the like adjacent thereto to also tend to direct the moisture from the laundry, food materials, paper slurry or the like toward the electrode means.

Claims Analysis
Total Claims: 24
Claim 1
Independent Claim
94 words
A method for removing retained moisture from moisture bearing web-like material of the moisture absorbing type comprising the steps of supporting said moisture bearing material with supporting means, disposing electrode means adjacent said supported material, moving said supported material, and creating a substantially constant electrostatic field action with said electrode means that will be imposed on at least some of the retained moisture of said moisture bearing material to cause the same to leave said material solely by the substantially constant electrostatic field action imposed thereon and while said supported material is being moved.
Claim 2
Independent Claim
94 words
A method for removing retained moisture from moisture bearing web-like material of the moisture absorbing type comprising the steps of supporting said moisture bearing material with supporting means, disposing electrode means adjacent said supported material, moving said supported material, and creating a substantially constant electrostatic field action with said electrode means that will be imposed on at least some of the retained moisture of said moisture bearing material to cause the same to leave said material solely by the substantially constant electrostatic field action imposed thereon and while said supported material is being moved.
Claim 3
Dependent Claim
29 words
A method as set forth in claim 1 wherein said step of creating said electrostatic field action comprises the step of creating an electrical charge on said electrode means.
Claim 4
Dependent Claim
38 words
A method as set forth in claim 2 wherein said step of disposing said electrode means adjacent said supported material comprises the step of disposing said charged electrode means out of electrical contact with said moisture bearing material.
Claim 5
Dependent Claim
23 words
A method as set forth in claim 3 wherein said charged electrode means tends to attract said moisture toward said charged electrode means.
Claim 6
Dependent Claim
41 words
A method as set forth in claim 4 wherein said step of creating said electrostatic field action comprises the step of tending to impose a charge on said retained moisture opposite to the polarity of the charge on said electrode means.
Claim 7
Dependent Claim
37 words
A method as set forth in claim 2 wherein said step of disposing said electrode means adjacent said supported material comprises the step of disposing said charged electrode means in electrical contact with said moisture bearing material.
Claim 8
Dependent Claim
29 words
A method as set forth in claim 2 wherein said step of creating said electrostatic field action comprises the step of disposing another electrode means adjacent said supported materiAl.
Claim 9
Dependent Claim
18 words
A method as set forth in claim 7 and including the step of grounding said other electrode means.
Claim 10
Dependent Claim
33 words
A method as set forth in claim 7 and including the step of causing said other electrode means to have a polarity opposite to the polarity of the first mentioned charged electrode means.
Claim 11
Dependent Claim
37 words
A method as set forth in claim 1 and including the step of changing the normal absorbed condition of said moisture bearing material during the time said electrostatic field action is acting on said moisture bearing material.
Claim 12
Dependent Claim
31 words
A method as set forth in claim 10 wherein said step of changing the normal absorbed condition of said moisture bearing material comprises the step of compressing said moisture bearing material.
Claim 13
Dependent Claim
26 words
A method as set forth in claim 11 wherein the step of compressing comprises the step of compressing said moisture bearing material against said supporting means.
Claim 14
Dependent Claim
15 words

Claim 15
Dependent Claim
15 words
A method as set forth in claim 1 wherein said support means is electrically non-conductive.
Claim 16
Dependent Claim
24 words
A method as set forth in claim 1 and including the step of charging at least one of said material and saId retained moisture.
Claim 17
Dependent Claim
26 words
A method as set forth in claim 1 and including the step of electrically grounding at least one of said material and said retained moisture thereof.
Claim 18
Dependent Claim
40 words
A method as set forth in claim 1 and including the step of compressing said moisture bearing material against said supporting means to tend to assist said electrostatic field action in removing said retained moisture from said moisture bearing material.
Claim 19
Dependent Claim
67 words
A method as set forth in claim 17 and including the step of moving said supporting means with said moisture bearing material thereon, said step of compressing said moisture bearing material comprising the step of moving compressing means in substantial unison with said supporting means whereby said moisture bearing material is being compressed between said compressing means and said supporting means during movement of said supporting means.
Claim 20
Dependent Claim
31 words
A method as set forth in claim 1 and including the step of assisting the electrostatic field action in causing at least some of the retained moisture to leave said material.
Claim 21
Dependent Claim
45 words
A method as set forth in claim 19 wherein said step of assisting the electrostatic field comprises the step of creating a fluid flow through said supported material in the direction of the movement of the retained moisture being removed by said electrostatic field action.
