Claims Analysis
Total Claims: 18
Claim 1
Independent Claim
103 words
An apparatus for the aeration and agitation of a body of fluid defining a surface level, comprising in combination a pumping device immersible into said fluid and including an upright conduit for delivering a stream of fluid above said surface level, a reaction turbine wheel suspended above said surface level and for rotation about an upright axis and having a plurality of radial channels communicating with said conduit, and fluid guiding means communicating with said conduit and receiving Said stream from the conduit and diverting and distributing said stream towards said radial channels for imparting a hydraulic reaction movement to said turbine wheel.
Claim 2
Independent Claim
103 words
An apparatus for the aeration and agitation of a body of fluid defining a surface level, comprising in combination a pumping device immersible into said fluid and including an upright conduit for delivering a stream of fluid above said surface level, a reaction turbine wheel suspended above said surface level and for rotation about an upright axis and having a plurality of radial channels communicating with said conduit, and fluid guiding means communicating with said conduit and receiving Said stream from the conduit and diverting and distributing said stream towards said radial channels for imparting a hydraulic reaction movement to said turbine wheel.
Claim 3
Dependent Claim
48 words
The apparatus as claimed in claim 1, wherein said radial channels have substantially vertical walls, and means are provided for adjusting the setting angle between the portions of the walls of said channels at the region of the circumference of said turbine wheel and the remaining wall portions.
Claim 4
Dependent Claim
22 words
The apparatus as claimed in claim 1, wherein means are provided for adjusting the position of said turbine wheel along said axis.
Claim 5
Dependent Claim
16 words
The apparatus as claimed in claim 1, wherein said turbine wheel is a hydraulic reaction wheel.
Claim 6
Dependent Claim
29 words
The apparatus as claimed in claim 1, said pumping device having an axial pumping wheel in said conduit and means for adjusting the delivery capacity of said pumping device.
Claim 7
Dependent Claim
24 words
The apparatus as claimed in claim 5, further comprising a housing for said pumping wheel, said housing being formed as an annular float means.
Claim 8
Dependent Claim
65 words
The apparatus as claimed in claim 5, further comprising a driving shaft for said pumping wheel, a plurality of conduits connected to a gas container means above said fluid surface, said conduits opening in the region of said pumping wheel below said fluid surface, said conduits delivering gas into said fluid body, and means for regulating the quantity of said gas flowing into said fluid.
Claim 9
Dependent Claim
