Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
64 words
A turbine alternator with a central clear optical path comprising: a hollow, cylindrical center tube defining said central clear optical path; a hollow, cylindrical assembly of turbine blades including a lower cylinder rotatably mounted on said center tube; at least one magnet mounted on the periphery of said lower cylinder of said assembly of turbine blades; and wire windings fixedly positioned about said magnets.
Claim 2
Dependent Claim
64 words
A turbine alternator with a central clear optical path comprising: a hollow, cylindrical center tube defining said central clear optical path; a hollow, cylindrical assembly of turbine blades including a lower cylinder rotatably mounted on said center tube; at least one magnet mounted on the periphery of said lower cylinder of said assembly of turbine blades; and wire windings fixedly positioned about said magnets.
Claim 3
Dependent Claim
29 words
The turbine alternator of claim 1 including the hollow, cylindrical center tube having means for inducting total air flow into the rotatably mounted, hollow, cylindrical assembly of turbine blades.
Claim 4
Dependent Claim
34 words
The turbine alternator of claim 2 wherein magnets are fixed coaxially to the outer periphery of the rotatably mounted, hollow, cylindrical assembly of turbine blades so as to introduce a current into the windings.
Claim 5
Dependent Claim
21 words
The turbine alternator of claim 3 wherein the fixed magnets function as a stator and rotate while the windings are motionless.
Claim 6
Dependent Claim
85 words
A turbine alternator with a central clear optical path comprising: a hollow, cylindrical center tube having a lower portion including air flow windows, said center tube defining said central clear optical path; means for sealing or baffling said lower portion of said hollow, cylindrical center tube; a hollow, cylindrical assembly of trubine blades rotatably mounted on said center tube by a system of ring bearings; rotating stator means fixed to said assembly of turbine blades; and wire windings fixedly positioned about said rotating stator means.
Claim 7
Dependent Claim
85 words
A turbine alternator with a central clear optical path comprising: a hollow, cylindrical center tube having a lower portion including air flow windows, said center tube defining said central clear optical path; means for sealing or baffling said lower portion of said hollow, cylindrical center tube; a hollow, cylindrical assembly of trubine blades rotatably mounted on said center tube by a system of ring bearings; rotating stator means fixed to said assembly of turbine blades; and wire windings fixedly positioned about said rotating stator means.
Claim 8
Dependent Claim
18 words
The turbine alternator of claim 5 including a means for relaying a signal created in the wire windings.
Claim 9
Dependent Claim
21 words
The turbine alternator of claim 6 wherein all air must exit through the rotatably mounted, hollow, cylindrical assembly of turbine blades.
