Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
134 words
In energy generating apparatus, the combination comprising (a) first and second tanks to receive liquid, (b) a primary float in the first tank to be elevated as the level of liquid in the first tank rises, and to be lowered when the level of liquid in the first tank falls, (c) a primary pump coupled to the float to pump liquid from the second tank in response to float movement vertically, in the first tank, and (d) primary means to generate energy in response to the flow of liquid to the first tank, (e) and an upper tank at a higher elevation than said first and second tanks, to receive liquid pumped from the second tank as well as liquid supplied from another source, and to supply liquid to flow to the first tank.
Claim 2
Dependent Claim
134 words
In energy generating apparatus, the combination comprising (a) first and second tanks to receive liquid, (b) a primary float in the first tank to be elevated as the level of liquid in the first tank rises, and to be lowered when the level of liquid in the first tank falls, (c) a primary pump coupled to the float to pump liquid from the second tank in response to float movement vertically, in the first tank, and (d) primary means to generate energy in response to the flow of liquid to the first tank, (e) and an upper tank at a higher elevation than said first and second tanks, to receive liquid pumped from the second tank as well as liquid supplied from another source, and to supply liquid to flow to the first tank.
Claim 3
Dependent Claim
81 words
The combination of claim 1 including a primary valve to pass liquid from the first tank to the second tank when the valve is opened, and a primary control operatively connected with the valve and located to sense the elevation of the float to effect closing of the valve when the float arrives at a first predetermined elevation, and to effect opening of the valve when the float arrives at a second predetermined elevation which is higher than said first elevation.
Claim 4
Dependent Claim
26 words
The combination of claim 2 wherein said control includes first and second float elevation sensors at two positions corresponding to said first and second float elevations.
Claim 5
Dependent Claim
36 words
The combination of any of claims 1-3 including gearing coupling the float to said pump, the gearing including a rack movable up and down with the float, and rotary gearing coupling the rack to the pump.
Claim 6
Dependent Claim
35 words
The combination of claim 2 wherein said (d) means includes a turbine located to be driven by liquid flow from the upper tank to the first tank, and an electrical generator coupled to said turbine.
Claim 7
Dependent Claim
27 words
The combination of claim 5 including a liquid flow duct extending between the upper tank and the turbine, and a control valve in series with said duct.
Claim 8
Dependent Claim
117 words
The combination of claim 5 including (e) third and fourth tanks to receive liquid, (f) a secondary float in the third tank to be elevated as the level of liquid in the third tank rises and to be lowered as the level of liquid in the third tank falls, (g) a secondary pump coupled to the secondary float to pump liquid from the fourth tank in response to secondary float movement vertically in the third tank, and (h) said primary means to generate energy being operable in response to flow of liquid to the third tank, (i) said upper tank located to receive liquid pumped from the fourth tank, and to supply liquid to the third tank.
Claim 9
Dependent Claim
87 words
The combination of claim 7 including a secondary valve to pass liquid from the third tank to the fourth tank when the valve is opened, and a secondary control operatively connected with the secondary valve and located to sense the elevation of the secondary float to effect closing of the secondary valve when the secondary float arrives at a first predetermined elevation, and to effect opening of the secondary valve when the secondary float arrives at a second predetermined elevation which is higher than said first elevation.
Claim 10
Dependent Claim
28 words
The combination of claim 7 wherein said secondary control includes first and second float elevation sensors at two positions corresponding to said first and second secondary float elevations.
Claim 11
Dependent Claim
40 words
The combination of any of claims 7-9 including gearing coupling the secondary float to said secondary pump, the gearing including a rack movable up and down with the secondary float, and rotary gearing coupling the rack to the secondary pump.
Claim 12
Dependent Claim
35 words
The combination of claim 7 wherein said turbine has a liquid discharge which is alternately supplied to said first and third tanks to effect alternating elevation of the primary and secondary floats in said tanks.
Claim 13
Dependent Claim
44 words
The combination of claim 11 including an actuator coupled to a turbine discharge duct to displace said duct between a primary position in which liquid is discharged to the first tank, and a secondary position in which liquid is discharged to the third tank.
Claim 14
Dependent Claim
75 words
The combination of claim 1 including a primary valve to drain liquid from the first tank to the second tank when the valve is opened, and means coupling the float to the pump for enabling the pump in its operation to resist descent of the float as the level of the draining liquid in the first tank falls beneath the primary float, whereby the full weight of the descending float acts to drive the pump.
Claim 15
Dependent Claim
86 words
The combination of claim 8 or any of claims 11-13 including a secondary valve to drain liquid from the third tank to said fourth tank when the secondary valve is open, and means coupling the secondary float to the secondary pump for enabling that pump in its operation to resist descent of the secondary float as the level of the draining liquid in the third tank falls beneath the secondary float, whereby the full weight of the descending secondary float acts to drive the secondary pump.
Claim 16
Dependent Claim
44 words
The combination of claim 1 wherein said primary pump has an intake, and including an intake pipe connected to said intake, and extending downwardly in the tank, said intake pipe having multiple inlets at different elevations, there being float controlled valves controlling said inlets.
