Abstract
Abstract Using a primary head of water, e.g., from natural source and flowing the water by gravity through an aspirator, a vacuum is produced which is utilized to lift a part of the water from the same source through multiple stages to any desired elevation. The stages may be operated in alternating sequence by selective connection to a common aspirator. Alternatively, by use of multiple aspirators two or more stages may be operated simultaneously for continuous flow. A series of reservoirs arranged with limited elevational differences are connected selectively to the suction line of a water-driven aspirator. The water may be stored temporarily in an elevated reservoir, from which it may be withdrawn to generate power and/or for other uses.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
280 words
A system for raising a desired liquid from a source of supply thereof, using a flowing stream of liquid which has sufficient fall to drive an aspirator with a substantial lifting force, said system comprising, in combination, an aspirator having a passageway for said flowing stream, an aspirating air inlet terminating within said flowing stream passageway, a single selectively operable control valve connected to said air inlet and having an outlet to the atmosphere, a first air-tight reservoir connected by a single air-tight line to said valve and located at an elevation higher than said source but within the height to which said aspirator can lift said desired liquid from said source a conduit for said desired liquid connected from said source to said first reservoir, a second air-tight reservoir also connected by a second single air-tight line to said valve and located at an elevation above said first reservoir but within the height to which the aspirator can lift said desired liquid from said first reservoir, a further conduit connected from the bottom of said first reservoir to the second reservoir for emptying the desired liquid from the first reservoir, sensor means in each of said reservoirs for producing a signal when its reservoir is full of the desired liquid, and valve operating means initiable in response to a signal from the sensor in a full reservoir to operate the valve, thereby to apply aspirator force to the other reservoir through its air-tight line and to connect the air-tight line of the full reservoir through the valve and its air outlet to the atmosphere, thereby to permit emptying of the full reservoir while the other reservoir is being filled.
Claim 2
Independent Claim
280 words
A system for raising a desired liquid from a source of supply thereof, using a flowing stream of liquid which has sufficient fall to drive an aspirator with a substantial lifting force, said system comprising, in combination, an aspirator having a passageway for said flowing stream, an aspirating air inlet terminating within said flowing stream passageway, a single selectively operable control valve connected to said air inlet and having an outlet to the atmosphere, a first air-tight reservoir connected by a single air-tight line to said valve and located at an elevation higher than said source but within the height to which said aspirator can lift said desired liquid from said source a conduit for said desired liquid connected from said source to said first reservoir, a second air-tight reservoir also connected by a second single air-tight line to said valve and located at an elevation above said first reservoir but within the height to which the aspirator can lift said desired liquid from said first reservoir, a further conduit connected from the bottom of said first reservoir to the second reservoir for emptying the desired liquid from the first reservoir, sensor means in each of said reservoirs for producing a signal when its reservoir is full of the desired liquid, and valve operating means initiable in response to a signal from the sensor in a full reservoir to operate the valve, thereby to apply aspirator force to the other reservoir through its air-tight line and to connect the air-tight line of the full reservoir through the valve and its air outlet to the atmosphere, thereby to permit emptying of the full reservoir while the other reservoir is being filled.
Claim 3
Dependent Claim
24 words
A system according to claim 1 where the conduit connected between the bottom of said first reservoir and the second reservoir is a U-tube.
Claim 4
Dependent Claim
20 words
A system according to claim 1 in which at least four reservoirs are serially connected to each other by U-tubes.
Claim 5
Dependent Claim
34 words
A system according to claim 1 in which the highest air-tight reservoir has its outlet connected to an open elevated storage reservoir located at a level which makes it capable of generating useful power.
Claim 6
Dependent Claim
23 words
A system according to claim 1, in which a high storage reservoir is located to receive water from the highest located water-raising reservoir.
Claim 7
Dependent Claim
60 words
A system according to claim 1, which includes at least four water-raising reservoirs, at least two of which connect to a single aspirator air inlet means for simultaneously filling at least said two reservoirs, and a further storage reservoir means for receiving and storing more water from the highest elevation of said water-raising reservoirs than said highest reservoir can hold.
Claim 8
Dependent Claim
35 words
A system according to claim 1, which includes a plurality of alternate water-raising reservoirs and means for alternately connecting a first said plurality and a second separate plurality of said reservoirs to a single aspirator.
Claim 9
Dependent Claim
32 words
A system according to claim 1, in which the valve has an atmospheric air inlet and including sensor means in at least one of the water-raising reservoirs connected to each air-tight line.
Claim 10
Dependent Claim
26 words
A system according to claim 1, in which the flowing liquid and the source of supply of desired liquid are obtained from the same liquid source.
