Patent ID: 7241340

Claim:
A system for applying a modifying composition differently sized and shaped substrates, comprising: a processing chamber configured for passing differently sized and shaped substrates therethrough, the processing chamber comprising: a first region; a second region; a constricted medial region between the first region and the second region; a first baffle separating the first region from the constricted medial region, the first baffle having an adjustable aperture sizable and configurable to accept the differently sized and shaped substrates; a second baffle separating the second region from the constricted medial region, the second baffle having an adjustable aperture sizable and configurable to accept the differently sized and shaped substrates; and wherein the processing chamber is further configured to accept a treatment mixture thereinto during movement of the differently sized and shaped substrates therethrough, where the treatment mixture comprises a modifying composition in a carrier medium selected from the group consisting of a supercritical fluid, a near-critical fluid, a superheated fluid, a superheated liquid, and a liquefied gas, the processing chamber being configured to initiate a pressure drop in the treatment mixture such that the modifying composition is released from the carrier medium and applied to the differently sized and shaped substrates within the processing chamber; an entry seal in communication with the first region of the processing chamber, the entry seal comprising at least one entry seal baffle having an adjustable aperture sizable and configurable to accept the differently sized and shaped substrates; and an exit seal in communication with the second region, the exit seal comprising at least one exit seal baffle having an adjustable aperture sizable and configurable to accept the differently sized and shaped substrates.
