Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
167 words
Contacting apparatus comprising in combination: a. a vertically disposed shell; b. horizontally disposed fluid-contacting devices fixed within said shell in spaced relationship, each said device comprising in combination i. a fixed first perforate member comprising a first plate element containing a plurality of parallel open slots unidirectionally traversing said first plate from side to side, said slots being separated by imperforate portions of said first plate element which are approximately as wide as the width of said slots; ii. a rotatable second perforate member contiguous to said first member comprising a second plate element containing a plurality of parallel open slots unidirectionally traversing said second plate from side to side, said slots being separated by imperforate portions of said second plate element which are approximately as wide as the width of said slots; and, c. means disposed externally of said shell and extending therethrough and operatively connecting with said second member for rotating each second member whereby the effective open area of corresponding slots may be varied.
