Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
219 words
A gas cooler assembly comprising: a first plate having opposing first and second surfaces, said first surface having a plurality of grooves adapted to carry a cooling gas and said second surface having a plurality of grooves adapted to carry a cooling gas, said first plate being comprised of a carbonized material; a second plate having opposing first and second surfaces, said first surface being flat and abutting said second surface of said first plate to define with said grooves of said second surface channels for carrying a cooling gas and said second surface of said second plate having a plurality of grooves of shallower depth than the grooves of the first and second surfaces of said first plate for carrying a process gas, said second plate being comprised of a carbonized material; and a third plate having opposing first and second surfaces, said first surface being flat and abutting said first surface of said first plate to define with said grooves of said first surface of said first plate channels for carrying a cooling gas and said second surface of said third plate having a plurality of grooves of shallower depth than the grooves of the first and second surfaces of said first plate for carrying a process gas, said third plate being comprised of a carbonized material.
Claim 2
Dependent Claim
219 words
A gas cooler assembly comprising: a first plate having opposing first and second surfaces, said first surface having a plurality of grooves adapted to carry a cooling gas and said second surface having a plurality of grooves adapted to carry a cooling gas, said first plate being comprised of a carbonized material; a second plate having opposing first and second surfaces, said first surface being flat and abutting said second surface of said first plate to define with said grooves of said second surface channels for carrying a cooling gas and said second surface of said second plate having a plurality of grooves of shallower depth than the grooves of the first and second surfaces of said first plate for carrying a process gas, said second plate being comprised of a carbonized material; and a third plate having opposing first and second surfaces, said first surface being flat and abutting said first surface of said first plate to define with said grooves of said first surface of said first plate channels for carrying a cooling gas and said second surface of said third plate having a plurality of grooves of shallower depth than the grooves of the first and second surfaces of said first plate for carrying a process gas, said third plate being comprised of a carbonized material.
Claim 3
Dependent Claim
61 words
An assembly in accordance with claim 1 wherein: said assembly is to provide a predetermined degree of cooling; said grooves in said second surface of said first plate are dimensioned to provide a first amount of said predetermined cooling; and said grooves in said first surface of said first plate are dimensioned to provide the remaining amount of said predetermined cooling.
