Abstract
Abstract Prefabricated rings comprising several arcuate sections and an expansion device are installed and frictionally retained in an inclined water conduit so as to dissipate the energy of the water descending therein, thereby slowing it to a velocity at which conduit wear and erosion and other harmful effects by the water in the conduit are acceptable.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
65 words
For use in a closed water conduit, an energy dissipator ring comprising a a plurality of arcuate precast sections which together form said ring, said ring sections having inwardly extending circumferentially spaced-apart plateaus, and b an expansion assembly between at least a pair of said sections for increasing the circumference of said ring so as to permit said ring to be force-fitted in said conduit.
Claim 2
Dependent Claim
65 words
For use in a closed water conduit, an energy dissipator ring comprising a a plurality of arcuate precast sections which together form said ring, said ring sections having inwardly extending circumferentially spaced-apart plateaus, and b an expansion assembly between at least a pair of said sections for increasing the circumference of said ring so as to permit said ring to be force-fitted in said conduit.
Claim 3
Dependent Claim
61 words
An inclined closed liquid-carrying conduit having a plurality of spaced-apart energy dissipator rings therein, each ring comprising: a a plurality of prefabricated ring sections, and b an expansion device between at least two of said sections for forcing said two sections apart so as to increase the circumference of said ring until it is frictionally locked in place in said conduit.
Claim 4
Dependent Claim
61 words
An inclined closed liquid-carrying conduit having a plurality of spaced-apart energy dissipator rings therein, each ring comprising: a a plurality of prefabricated ring sections, and b an expansion device between at least two of said sections for forcing said two sections apart so as to increase the circumference of said ring until it is frictionally locked in place in said conduit.
Claim 5
Dependent Claim
15 words
The conduit of claim 2 characterized further in that said ring sections are precast concrete.
Claim 6
Dependent Claim
25 words
The conduit of claim 2 characterized further in that said rings are stepped in cross section so as to form inwardly extending circumferentially spaced-apart plateaus.
Claim 7
Dependent Claim
39 words
The conduit of claim 4 characterized further in that alternate ones of said rings are so positioned within said conduit that the plateaus of one ring are in alignment with the spaces between the plateaus of an adjacent ring.
Claim 8
Dependent Claim
38 words
The conduit of claim 2 characterized further in that each ring additionally includes structurally interfitting alignment means on at least two adjacent sections of said ring, and a drainage notch on at least one section of said ring.
