Abstract
Abstract A modular imaging electrode assembly for supplying liquids in automated imaging machines. The unit has a tank holding a roller coupled to an electrical source. The roller is driven past a liquid applying and leveling apparatus and then contacts an imaging member of the machine in which it is located. The tank which is elevated into and out of contact with the member of the machine has two or more sections. The first houses the apparatus to apply liquid to the roller and the second has cleaning brushes in it to remove any materials remaining on the roller. Optionally, a third section applies a different liquid to the roller. The sections are separated by squeegees for preventing material in the one section from affecting that in another.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
141 words
Apparatus for imaging electrophoretic particles suspensions including: a first electrode adapted to support an image formed from the suspension; at least another electrode with a surface capable of moving for contacting the suspension at a predetermined position between the electrodes; means for applying an electric field across the suspension at the predetermined position; means for exposing the suspension with activating electromagnetic radiation; a tank adapted to support said another electrode for movement in the tank and having a plurality of sections around a position of the surface of said another electrode including; a first section having at least one applicator member adapted to contact the surface of said another electrode; a second section having cleaning means to remove matter from the surface of said another electrode, and divider means to separate said first section from said second seCtion in said tank.
Claim 2
Dependent Claim
141 words
Apparatus for imaging electrophoretic particles suspensions including: a first electrode adapted to support an image formed from the suspension; at least another electrode with a surface capable of moving for contacting the suspension at a predetermined position between the electrodes; means for applying an electric field across the suspension at the predetermined position; means for exposing the suspension with activating electromagnetic radiation; a tank adapted to support said another electrode for movement in the tank and having a plurality of sections around a position of the surface of said another electrode including; a first section having at least one applicator member adapted to contact the surface of said another electrode; a second section having cleaning means to remove matter from the surface of said another electrode, and divider means to separate said first section from said second seCtion in said tank.
Claim 3
Dependent Claim
26 words
The apparatus of claim 1 further including a squeegee adjustably positioned within the second section of said tank to contact the surface of said another electrode.
Claim 4
Dependent Claim
35 words
The apparatus of claim 1 wherein said tank has further associated therewith a means for moving said tank and said another electrode wherein said another electrode is moved into and out of the predetermined position.
Claim 5
Dependent Claim
26 words
The apparatus of claim 1 including a third section having wetting means to contact the another electrode surface and being capable of applying a liquid thereto.
Claim 6
Dependent Claim
20 words
The apparatus of claim 4 including second divider means for separating said third section from said first and second sections.
Claim 7
Dependent Claim
27 words
The apparatus of claim 4 wherein said wetting means includes at least one roller positioned within said third section to contact the surface of the another electrode.
Claim 8
Dependent Claim
31 words
The apparatus of claim 4 including moving means operatively associated with said wetting means to move said wetting means into and out of contact with the surface of said another electrode.
