Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
147 words
For use with a crossflow water cooling tower having a hot water distributor for distributing water onto the splash type fill assembly structure, a cold water basin and means for inducing crossflow movement of air therebetween, a combination therewith of splash type fill assembly structure comprising, a series of elongated generally horizontal fill members; means supporting the fill members in the space between the hot water distributor and said cold water basin in horizontal and vertical spaced relationship; said fill members having their longitudinal axis generally parallel with the direction of air flow and said fill members having two substantially flat imperforated upper surface elements, a lower substantially flat partially imperforate element having intermittent transverse imperforate strips along its length and two vertically elongated imperforated elements one each connecting each upper surface element with the lower substantially flat element for passage and dispersal of liquid falling thereon.
Claim 2
Dependent Claim

Claim 3
Dependent Claim
27 words
The splash type fill assembly structure as set forth in claim 1 wherein the upper surface elements are narrow and the lower flat element is substantially wide.
Claim 4
Dependent Claim
34 words
A splash type fill assembly of claim 1 wherein there are located along the entire length of the fill members snap lock elements on the outer edges of the flat elongated upper surface elements.
Claim 5
Dependent Claim
30 words
A splash type fill assembly structure of claim 1 wherein said fill members are in relative offset relationship in said supporting means with respect to fill members thereabove or therebelow.
Claim 6
Dependent Claim
24 words
A splash type fill assembly structure of claim 1 wherein the width of the two substantially flat elongated imperforate surface elements are the same.
Claim 7
Dependent Claim
34 words
A splash type fill assembly structure of claim 1 wherein the ratio of perforate to imperforate area of the entire water encountered plan view of said fill assembly structure is approximately 33 to 67.
Claim 8
Dependent Claim
67 words
The splash type fill assembly structure of claim 1 wherein the width of the two substantially flat elongated imperforate upper surface elements is approximately 1/2 inch, the width of the lower substantially flat partially imperforate element is approximately 5 to 6 inches, the width of the vertical elongated imperforate element is 3/4 to 11/2 inches, the width of the intermittent transverse imperforate strips is about 1/2 inch.
Claim 9
Dependent Claim
35 words
The splash type fill assembly structure of claim 1 wherein the ratio of perforate to imperforate area of only the perforated section of the lower substantially flat partially imperforate element is approximately 55 to 45.
