Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
122 words
A trickling assembly for cooling towers, which includes: a plurality of trickling plates arranged substantially parallel and in horizontally spaced relationship to each other, lattice means supported by some of said trickling plates and having at least a portion thereof arranged at a level lower than said trickling plates, spray slats arranged at a level below said trickling plates, said spray slats extending substantially horizontally and being supported by said lattice means in vertically spaced relationship to each other, a portion of said lattice means respectively extending between adjacent trickling plates to the upper ends thereof, and rod means extending through meshes at the upper ends of said lattice means and resting on the respective adjacent upper ends of said trickling plates.
Claim 2
Dependent Claim
122 words
A trickling assembly for cooling towers, which includes: a plurality of trickling plates arranged substantially parallel and in horizontally spaced relationship to each other, lattice means supported by some of said trickling plates and having at least a portion thereof arranged at a level lower than said trickling plates, spray slats arranged at a level below said trickling plates, said spray slats extending substantially horizontally and being supported by said lattice means in vertically spaced relationship to each other, a portion of said lattice means respectively extending between adjacent trickling plates to the upper ends thereof, and rod means extending through meshes at the upper ends of said lattice means and resting on the respective adjacent upper ends of said trickling plates.
Claim 3
Dependent Claim
25 words
An assembling according to claim 1, in which those trickling plates on which said lattice means are suspended are stronger than the remaining trickling plates.
Claim 4
Dependent Claim
31 words
An assembly according to claim 1, in which the planes defined by said spray slats are substantially at a right angle with regard to the planes defined by said lattice means.
Claim 5
Dependent Claim
31 words
An assembly according to claim 1, which includes additional lattice means arranged below said first-mentioned lattice means, and sleeve means connecting said last mentioned lattice means to said first-mentioned lattice means.
Claim 6
Dependent Claim
52 words
An assembly according to claim 1, in which said lattice means comprises vertically spaced horizontal strut means arranged at that portion of said lattice means which is at a level lower than said trickling plates, and which include substantially horizontally extending spacer means respectively resting on said vertically spaced horizontal strut means.
Claim 7
Dependent Claim
22 words
An assembly according to claim 5, in which those areas of said spacer means which rest on said strut means are notched.
