Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
132 words
A spacer-turbulator portion of cooling tower corrugated fill sheets for separating said sheets and imparting corkscrew turbulence to air passing between said sheets which comprises: a. raised mound means at the downstream portion of the spacer-turbulator for maintaining each fill sheet apart from an adjoining sheet, said mound means contacting the fill sheet at the base of a concave portion of the fill sheet and contacting the adjoining fill sheet at the base of its concave portion, said means being in repeating units; and b. raised means between each of the raised mound means extending from the apex of a convex portion of a fill sheet outward and in opposite directions toward each concave portion of the same fill sheet, said raised means defining with the adjoining fill sheet an air space.
Claim 2
Dependent Claim
132 words
A spacer-turbulator portion of cooling tower corrugated fill sheets for separating said sheets and imparting corkscrew turbulence to air passing between said sheets which comprises: a. raised mound means at the downstream portion of the spacer-turbulator for maintaining each fill sheet apart from an adjoining sheet, said mound means contacting the fill sheet at the base of a concave portion of the fill sheet and contacting the adjoining fill sheet at the base of its concave portion, said means being in repeating units; and b. raised means between each of the raised mound means extending from the apex of a convex portion of a fill sheet outward and in opposite directions toward each concave portion of the same fill sheet, said raised means defining with the adjoining fill sheet an air space.
Claim 3
Dependent Claim
47 words
A spacer-turbulator according to claim 1 wherein the raised mound means contacts the adjacent fill sheet only at the mound's apex which is at the concave portion of the adjoining fill sheet and the base of said mound contacts the fill sheet at its own concave portion.
Claim 4
Dependent Claim
72 words
A spacer-turbulator according to claim 1 wherein the raised means between each of the raised mound means extends from the apex of a convex portion of a fill sheet outward and in opposite directions so that said means communicates with the base of each mound means of part a) said raised means between each of the raised mound means defining an air space with the convex portion of the adjoining fill sheet.
Claim 5
Dependent Claim
39 words
A spacer-turbulator of claim 3 wherein there is mound means at the apex of each convex portion of a fill sheet, said mound means being an integral portion of the raised means between each of the raised mound means.
Claim 6
Dependent Claim
25 words
A spacer-turbulator of claim 3 wherein the means between each of the raised mound means is beveled and slanted in the direction of air flow.
