Abstract
Abstract A solution agitation system to provide a uniform and controlled turbulent flow of treatment liquid over both sides of a flat substrate which is suspended in a treatment solution, wherein a directed liquid spray pattern below the treatment solution level creates parallel, flowing walls of solution running downward through the tank and on each opposite side of the substrate.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
129 words
A system for agitating treatment solutions in treating substrates and the like, comprising: A. a tank for containment of the treating solution; B. means for operatively suspending a substrate immersed in the treatment solution; and C. means for implementing a uniform and controlled turbulent flow of the treatment solution over the sides of the substrate, comprising spray nozzles positioned in the tank on opposite sides of the substrate, parallel thereto and below the surface of said treatment solution, whereby said spray nozzles create a flat overlapping spray pattern below the solution surface, directed downwardly from top to bottom along the substrate, wherein said directed spray pattern provides two parallel, flowing walls of solution running from the top of the tank to the bottom along opposite sides of the substrate.
Claim 2
Independent Claim
129 words
A system for agitating treatment solutions in treating substrates and the like, comprising: A. a tank for containment of the treating solution; B. means for operatively suspending a substrate immersed in the treatment solution; and C. means for implementing a uniform and controlled turbulent flow of the treatment solution over the sides of the substrate, comprising spray nozzles positioned in the tank on opposite sides of the substrate, parallel thereto and below the surface of said treatment solution, whereby said spray nozzles create a flat overlapping spray pattern below the solution surface, directed downwardly from top to bottom along the substrate, wherein said directed spray pattern provides two parallel, flowing walls of solution running from the top of the tank to the bottom along opposite sides of the substrate.
Claim 3
Dependent Claim
60 words
A system as claimed in claim 1 including a high volume, high pressure pump drawing solution from the bottom of the tank, said spray nozzles being operatively mounted to a dual manifold positioned on opposite sides of said tank and supplied by pump effluent, said manifolds and nozzles thereon being positioned parallel to and just below the treatment solution surface.
Claim 4
Dependent Claim
64 words
A system as claimed in claim 2 including flow control valves mounted to each manifold, a pump bypass line connected to the effluent side of said pump, a valve in said bypass line for regulation of the amount of fluid being drawn through the high volume, high pressure pump, solution flow in said manifolds being controlled by adjusting said manifold and pump bypass valves.
Claim 5
Dependent Claim
22 words
A system as claimed in claim 2 including elbows mounting each said manifold to allow spacing between the manifolds to be adjusted.
Claim 6
Dependent Claim
19 words
A system as claimed in claim 1 including means for thermostatically monitoring and controlling solution temperature in said tank.
