Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
103 words
In an aeration system including header means arranged in a tank on support means in generally horizontal relationship with diffusers spaced at longitudinal intervals along said header means, the improvement which comprises means to adjust the orientation of said diffusers with regard to said tank by rotating said header means, said improvement comprising: first connecting means secured to the outer surface of said header means and integral therewith; second connecting means on said support means; and rotation means, connected between said first and second connecting means, for rotating said header means about its longitudinal axis to thereby adjust the orientation of said diffusers.
Claim 2
Dependent Claim
103 words
In an aeration system including header means arranged in a tank on support means in generally horizontal relationship with diffusers spaced at longitudinal intervals along said header means, the improvement which comprises means to adjust the orientation of said diffusers with regard to said tank by rotating said header means, said improvement comprising: first connecting means secured to the outer surface of said header means and integral therewith; second connecting means on said support means; and rotation means, connected between said first and second connecting means, for rotating said header means about its longitudinal axis to thereby adjust the orientation of said diffusers.
Claim 3
Dependent Claim
42 words
Apparatus according to claim 1 wherein said header means includes a plurality of header sections arranged in end-to-end relationship to provide joints between said sections, wherein said support means includes a support member having cradle means in which said joint is supported.
Claim 4
Dependent Claim
16 words
Apparatus according to claim 1 wherein said rotation means secures said header in said support means.
Claim 5
Dependent Claim
36 words
Apparatus according to claim 1 wherein said header includes a plurality of diffuser connectors spaced at longitudinal intervals along said header and extending transversely therefrom, and wherein said diffusers extend laterally and horizontally from said header.
Claim 6
Dependent Claim
21 words
Apparatus according to claim 1 wherein said first connecting means includes lug means secured to the outer surface of said header.
Claim 7
Dependent Claim
18 words
Apparatus according to claim 1 wherein said second connecting means includes lug means secured to said support means.
Claim 8
Dependent Claim
43 words
Apparatus according to claim 1 wherein said rotation means includes a first threaded member inter-connected with said first and second connecting means and a second threaded member engaging the second connecting member and threadedly engaging the first threaded member for rotating said header.
Claim 9
Dependent Claim
57 words
Apparatus according to claim 1 wherein said second connecting means includes lug means extending from said support means and said rotation means includes a threaded member interconnected with said first connecting means and extending through said lug means and a nut threadedly engaging said threaded member for advancement thereon against said lug means for rotating said header.
Claim 10
Dependent Claim
46 words
The apparatus of claim 1 in which said first connection means prevents relative movement between said rotation means and said header means whereby adjustment of said second connecting means causing rotation of said rotation means results in rotation of said header means about its longitudinal axis.
