Abstract
Abstract ABSTRACT A dissipator basin for reducing the kinetic energy of water exiting from steeply sloped highway culverts, spillways and the like which is especially useful in mountainous country. A substantially rectangular basin is provided with a massive impact block shaped so that water from the culvert strikes the underside of an upwardly and rearwardly facing projection which causes the water to be swept downwardly and rearwardly as a downward vortex which tends to dissipate the kinetic energy as heat.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
92 words
A device for reducing the kinetic energy of a fluid freely flowing along a fluid flowpath, comprising: (a) basin means having an upstream fluid inlet and a downstream fluid outlet, for placement in said flowpath; (b) an impact surface in said basin and angularly traversing at least a portion of said fluid flowpath and arranged to create a vortex in said fluid in said basin adjacent the fluid inlet thereof; and (c) flowpath means in said basin adjacent said impact surface to permit fluid flow between said vortex and said fluid outlet.
Claim 2
Independent Claim
92 words
A device for reducing the kinetic energy of a fluid freely flowing along a fluid flowpath, comprising: (a) basin means having an upstream fluid inlet and a downstream fluid outlet, for placement in said flowpath; (b) an impact surface in said basin and angularly traversing at least a portion of said fluid flowpath and arranged to create a vortex in said fluid in said basin adjacent the fluid inlet thereof; and (c) flowpath means in said basin adjacent said impact surface to permit fluid flow between said vortex and said fluid outlet.
Claim 3
Dependent Claim
13 words
A device as claimed in claim 1 wherein said fluid is a liquid.
Claim 4
Dependent Claim
12 words
A device as claimed in claim 2 wherein said liquid is water.
Claim 5
Dependent Claim
20 words
A device as claimed in claim 1, 2 or 3 wherein said basin includes weir means adjacent said fluid outlet.
Claim 6
Dependent Claim
24 words
A device as claimed in claim 1, 2 or 3 wherein said impact surface is provided on an impact block mounted in said basin.
Claim 7
Dependent Claim
40 words
A device as claimed in claim 1, 2 or 3 wherein said impact surface is provided on an impact block mounted on a lower surface of said basin so as to create a vortex having a horizontal axis of rotation.
Claim 8
Independent Claim
110 words
A device for reducing the kinetic energy of water freely flowing along a flowpath between conduit means and a natural waterway, comprising: (a) basin means having an upstream fluid inlet and a downstream fluid outlet, for placement in said flowpath adjacent said conduit means; (b) an impact block mounted in said basin and having an impact surface angularly traversing at least a portion of said flowpath and arranged so as to create a vortex in said water in said basin upstream of said impact block; and (c) passage means between said impact block and said basin to permit said water to flow from said vortex to said downstream fluid outlet.
Claim 9
Independent Claim
110 words
A device for reducing the kinetic energy of water freely flowing along a flowpath between conduit means and a natural waterway, comprising: (a) basin means having an upstream fluid inlet and a downstream fluid outlet, for placement in said flowpath adjacent said conduit means; (b) an impact block mounted in said basin and having an impact surface angularly traversing at least a portion of said flowpath and arranged so as to create a vortex in said water in said basin upstream of said impact block; and (c) passage means between said impact block and said basin to permit said water to flow from said vortex to said downstream fluid outlet.
Claim 10
Dependent Claim
44 words
A device as claimed in claim 7 wherein said basin has sidewalls and a rearwall between D and 2D and a front wall between 0.5 and D high, is about 4D wide and about 6D long, where D is the diamter of the conduit.
Claim 11
Dependent Claim
31 words
A device as claimed in claim 1 wherein said impact block has a substantially rhomboidal base axially aligned with said culvert and an angularly upwardly extending projection directed towards said conduit.

Dependent Claim
20 words
A device as claimed in claim 9 wherein a lower face of said upwardly extending projection provides said impact surface.
Claim 13
Dependent Claim
37 words
A device as claimed in claim 10 wherein said impact block is mounted on a horizontally disposed base of said basin so as to produce a downward vortex in said water between said base and said projection.
Claim 14
Dependent Claim
27 words
A device as claimed in claim 11 wherein said impact surface is at an angle between 30 and 40° to a horizontally disposed base of said basin.
Claim 15
Dependent Claim
23 words
A device as claimed in claim 12 wherein said impact surface is at an angle of about 35° to said horizontally disposed base.
Claim 16
Dependent Claim
32 words
A device as claimed in claim 11 or 12 wherein a rear face of said rhomboidal base is inclined at an angle between 65° and 80° relative to said horizontally disposed base.
