Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
19 words
A system according to claim 1, wherein said fluid comprises about 3 to 25 percent of water by weight.
Claim 2
Dependent Claim
17 words
A system according to claim 1, wherein the expander is a turbine, piston engine or helical screw.
Claim 3
Dependent Claim
11 words
A vehicle driven by a prime mover system according to claim
Claim 4
Dependent Claim
71 words
In the conversion of heat into motive power by vaporizing and superheating a portion of the fluid in a reservoir and then allowing said fluid vapor to expand, condense and return to said reservoir, said expansion moving a member, the improvement which comprises heating said fluid to a temperature of about 400* to 750* F., said fluid consisting essentially of trifluoroethanol containing about 1 to 40 percent of water by weight.
Claim 5
Dependent Claim
17 words
A process according to claim 5, wherein said fluid is heated to about 400* to 600* F.
Claim 6
Dependent Claim
42 words
A process according to claim 5, wherein, the fluid vapor prior to expansion is under a maximum pressure of about 300 to 1, 500 psia, the tendency toward decomposition fostered by said pressure being counteracted by the stabilizing effect of said water.
Claim 7
Dependent Claim
19 words
A process according to claim 7, wherein said fluid comprises about 3 to 25 percent of water by weight.
Claim 8
Dependent Claim
18 words
A process according to claim 6, wherein said moving member is a reciprocating piston and drives a vehicle.
Claim 9
Dependent Claim
18 words
A process according to claim 9, wherein said moving member is a turbine blade and drives a vehicle.
