Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
92 words
In a system wherein a fluid exhibits a regressive vapor dome in a T-S diagram, the combination comprising (a) a two-phase nozzle receiving said fluid in a pressurized and heated liquid state and expanding said received liquid into a saturated or superheated vapor state in a vapor jet, and (b) turbine means receiving only said saturated or superheated vapor in jet form to convert the kinetic energy thereof into power, (c) said nozzle being separate from the turbine means so that said jet is formed before its reception in the turbine means.
Claim 2
Dependent Claim
92 words
In a system wherein a fluid exhibits a regressive vapor dome in a T-S diagram, the combination comprising (a) a two-phase nozzle receiving said fluid in a pressurized and heated liquid state and expanding said received liquid into a saturated or superheated vapor state in a vapor jet, and (b) turbine means receiving only said saturated or superheated vapor in jet form to convert the kinetic energy thereof into power, (c) said nozzle being separate from the turbine means so that said jet is formed before its reception in the turbine means.
Claim 3
Dependent Claim
22 words
The combination of claim 1 wherein said turbine means includes an impulse vapor turbine receiving said vapor jet to drive the turbine.
Claim 4
Dependent Claim
30 words
The combination of claim 2 wherein said turbine means also includes a reaction vapor turbine receiving the vapor discharged from said impulse vapor turbine, to drive the reaction vapor turbine.
Claim 5
Dependent Claim
29 words
The combination of claim 1 including other means operatively connected with said turbine means for condensing the expanded vapor, for re-pressurizing and heating same for re-delivery to said nozzle.
Claim 6
Dependent Claim
34 words
The combination of claim 3 including other means operatively connected between said reaction vapor turbine and said nozzle for condensing the expanded vapor and for re-pressurizing and heating same for re-delivery to the nozzle.
Claim 7
Dependent Claim
20 words
