Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
180 words
A jet flow alternator for directing the flow of a fluid substance in a select direction comprising, in combination, an outer cylindrical shell, a pipe of lesser diameter than said shell extending axially through said shell and through which a substance flows, means at the ends of said shell closing the space between the shell and pipe to provide a cylindrical chamber between them, a plurality of superposed tubes mounted around said pipe, said tubes being shiftable with respect to each other and said pipe, a plurality of circumferentially and axially spaced apertures in said tubes and pipe, said apertures being aligned normally to provide fluid passageways, means to deliver pressurized fluid of greater pressure than in said pipe into said chamber for passage through said passageways into the interior of the pipe, and means to shift the tubes relative to the pipe and to each other to offset the apertures in the tubes with respect to the apertures in the pipe to direct the pressurized fluid entering the pipe through said passageways towards a selected end of the alternator.
Claim 2
Dependent Claim
180 words
A jet flow alternator for directing the flow of a fluid substance in a select direction comprising, in combination, an outer cylindrical shell, a pipe of lesser diameter than said shell extending axially through said shell and through which a substance flows, means at the ends of said shell closing the space between the shell and pipe to provide a cylindrical chamber between them, a plurality of superposed tubes mounted around said pipe, said tubes being shiftable with respect to each other and said pipe, a plurality of circumferentially and axially spaced apertures in said tubes and pipe, said apertures being aligned normally to provide fluid passageways, means to deliver pressurized fluid of greater pressure than in said pipe into said chamber for passage through said passageways into the interior of the pipe, and means to shift the tubes relative to the pipe and to each other to offset the apertures in the tubes with respect to the apertures in the pipe to direct the pressurized fluid entering the pipe through said passageways towards a selected end of the alternator.
Claim 3
Dependent Claim
25 words
The jet flow alternator recited in claim 1, wherein mechanical means is provided to shift the tubes relative to each other and to the pipe.
Claim 4
Dependent Claim
25 words
The jet flow alternator recited in claim 1, wherein the outer cylindrical shell of the jet flow alternator constitutes the shaft of a drilling rig.
Claim 5
Dependent Claim
22 words
The jet flow alternator recited in claim 1, wherein there are three tubes telescoped one into the other and around the pipe.
Claim 6
Dependent Claim
22 words
The jet flow alternator recited in claim 1, wherein there are two tubes telescoped one into the other and around the pipe.
Claim 7
Dependent Claim
23 words
The jet flow alternator recited in claim 1, wherein the tubes are shifted axially one relative to each other and to the pipe.
Claim 8
Dependent Claim
30 words
The jet flow alternator recited in claim 1, wherein the alternator extends through a water tight float and means is provided to submerge the float in a body of water.
Claim 9
Dependent Claim
124 words
In a dredge including a suction line having an open free end resting on the bottom of a body of water, a plurality of superposed telescopic perforated tubes mounted around the free end of said suction line, said suction line including a plurality of perforations, a housing enclosing said tubes and providing an enclosed chamber therearound, means to deliver pressurized fluid of greater pressure than in said suction line to said chamber for passage into the suction line through the perforations, and means to shift the tubes relative to one another and to said suction line to offset the perforations in the tubes relative to the perforations in said suction line for directing the pressurized fluid in a selected direction in said suction line.
Claim 10
Dependent Claim
124 words
In a dredge including a suction line having an open free end resting on the bottom of a body of water, a plurality of superposed telescopic perforated tubes mounted around the free end of said suction line, said suction line including a plurality of perforations, a housing enclosing said tubes and providing an enclosed chamber therearound, means to deliver pressurized fluid of greater pressure than in said suction line to said chamber for passage into the suction line through the perforations, and means to shift the tubes relative to one another and to said suction line to offset the perforations in the tubes relative to the perforations in said suction line for directing the pressurized fluid in a selected direction in said suction line.
