Abstract
Abstract Thin sheet apparatus having a central area and a frame area around the central area. The frame area contains supply orifices and drainage orifices. The frame area contains a plurality of micro-channels leading from each of the supply orifices toward the central area. The plurality of microchannels leading from each orifice diverge from each other in the direction away from the orifice.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
191 words
A THIN SHEET APPARATUS COMPRISING A CENTRAL AREA AND A FRAME AREA AROUND SAID CENTRAL AREA, SAID FRAME AREA CONTAINING SUPPLY ORIFICES IN THE ONE SIDE THEREOF, AND DRAINAGE ORIFICES IN THE OPPOSITE SIDE THEREOF, SAID FRAE AREA CONTAINING A PLURALITY OF MICRO-CHANNELS LEADING FROM EACH O SAID SUPPLY ORIFICES TOWARD SAID CENTRAL AREA AND ADAPTED TO SUPPLY LIQUID FRM SAID SUPPLY ORIFICES TO THE SURFACE OF SAID CENRAL AREA, THE SAID PLURALITY OF MICROCHANNELS LEADING FROM EACH OF SAID ORIFICES COMPRISING A GROUP OF MICRO-CHANNELS WITH THE TWO MICRO-CHANNELS FORMING SAID GROUP DIVERGING FROM EACH OTHER IN THE DIRECTION AWAY FROM ORIFICE EACH OF SAID MICRO-CHANNELS COMPRISING THE SAID PLURALITY OF MICRO-CHANNELS LEADING FROM EACH OF SAID ORIFICES HAVING A CROSS-SECTIONAL AREA VARYING RELATIVE TO THE ROSS-SECTIONAL AREA OF EACH OF THE OTHER OF SAID MICRO-CHANNELS IN PROPORTION TO THEIR RESPECTIVE LENGTHS, AND SAID FRAME CONTAINING A FLUID DISTRIBUTION AREA IN SAID FRAME POSITIONED BETWEEN THE SUPPLY MICRO-CHANNELS AND THE SIDE OF SAID ELECTRODE TOWARD WHICH SAID SUPPLY MICROCHANNELS LEAD AND ABUTTING SAID SIDE OF SAID ELECTRODE, SAID FLUID DISTRIBUTION AREA HAVING APLURALITY OF SPACED PROJECTIONS ACROSS THE AREA THEREOF,

Claim 3
Dependent Claim
126 words
The apparatus of claim 1 wherein a group of micro-channels diverge from each of said drainage orifices toward said central area and are adapted to drain liquid from the surface of said central area; wherein the micro-channels in each of said groups diverging from the supply orifices and from the drainage orifices, are equidistant from the adjacent micro-channels in the same group when measured along a plane parallel to the side of said central area toward which said micro-channels lead; and wherein the micro-channels in each of said groups which do not diverge from an orifice positioned adjacent one side of said central area are symmetrical about a central plane perpendicular to the side of said central area toward which the group of said micro-channels lead.
Claim 4
Dependent Claim
85 words
Apparatus of claim 2 containing a fluid distribution area in said frame area positioned between the supply micro-channels and the side of said central area toward which said supply micro-channels lead and abutting said side of said central area, and containing a fluid distribution area in said frame area and positioned between the drainage micro-channels and the side of said central area and abutting said side of said central area, said fluid distribution areas having a plurality of equidistant spaced projections across the areas thereof.
Claim 5
Dependent Claim
34 words
The apparatus of claim 3 wherein the number of micro-channels comprising said plurality of micro-channels diverging from each of said drainage orifices is greater than the number diverging from each of said supply orifices.
