Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
102 words
A hydrogen supplementally fueled diesel powered locomotive comprising: (a) a conventional diesel electric locomotive having a diesel engine as its prime mover, (b) traction motors mounted in said locomotive adapted for dynamic braking of said locomotive and adapted to generate electricity when actuated, (c) at least one electrolysis cell for the electrolytic decomposition of water, (d) means coupled to said traction motors and to said, at least one, electrolysis cell to deliver electricity from said traction motors to said cell upon dynamic braking to generate hydrogen, (e) means for supplying generated hydrogen to said diesel engine as a fuel for said engine.
Claim 2
Dependent Claim
102 words
A hydrogen supplementally fueled diesel powered locomotive comprising: (a) a conventional diesel electric locomotive having a diesel engine as its prime mover, (b) traction motors mounted in said locomotive adapted for dynamic braking of said locomotive and adapted to generate electricity when actuated, (c) at least one electrolysis cell for the electrolytic decomposition of water, (d) means coupled to said traction motors and to said, at least one, electrolysis cell to deliver electricity from said traction motors to said cell upon dynamic braking to generate hydrogen, (e) means for supplying generated hydrogen to said diesel engine as a fuel for said engine.
Claim 3
Dependent Claim
17 words
The locomotive of claim 1 including: (g) means for separately storing oxygen generated in said electrolysis cell.
Claim 4
Dependent Claim
17 words
The locomotive of claim 2 further including: (h) means for supplying stored oxygen to said diesel engine.
Claim 5
Dependent Claim
21 words
In the locomotive of claim 1 further including storage means for storing hydrogen generated in said at least one electrolysis cell.
Claim 6
Independent Claim
30 words
The method of supplementing the power of a diesel electric locomotive for heavy local conditions, which comprises: (a) dynamically braking the locomotive upon descent of hills, to generate D.C. current;
Claim 7
Independent Claim
30 words
The method of supplementing the power of a diesel electric locomotive for heavy local conditions, which comprises: (a) dynamically braking the locomotive upon descent of hills, to generate D.C. current;
Claim 8
Dependent Claim
45 words
(b) energizing on electrolysis cell containing water to separate the water into H 2 and O 2 , said cell being disposed in the locomotive or some other car of said train, (c) feeding the H 2 gas into the diesel engine of said locomotive.
Claim 9
Dependent Claim
45 words
(b) energizing on electrolysis cell containing water to separate the water into H 2 and O 2 , said cell being disposed in the locomotive or some other car of said train, (c) feeding the H 2 gas into the diesel engine of said locomotive.
Claim 10
Dependent Claim
25 words
The method of claim 5, further including storing the H 2 gas after the preparation thereof, prior to feeding the gas to the diesel engine.
Claim 11
Dependent Claim
19 words
The method of claim 5 including feeding at least a portion of the O 2 into the diesel engine.
Claim 12
Dependent Claim
22 words
The method of claim 7 further including the step of supplementing the O 2 with air for use in the diesel engine.
Claim 13
Dependent Claim
17 words
The method of claim 5 including the step of storing the O 2 after the preparation thereof.
