Abstract
Abstract A fuel producing system for a solid/liquid mixture. The system comprises a mixing reservoir having a first inlet for receiving a combustible liquid fuel, and a second inlet for receiving a solid fuel pulverized to a mixable state with said liquid fuel. Mixing means is provided in the mixing reservoir to mix both fuels. Quantitative control means is also provided in the reservoir to measure predetermined amounts of the liquid and solid fuels delivered therein. A holding reservoir receives the solid/liquid fuel mixture from an output conduit of the mixing reservoir. Pump means is provided in the output conduit. First control means is further provided to shut off the flow of the fuel mixture to the holding reservoir to permit the mixing of further fuel mixture in the mixing reservoir. A second control means initiates the flow of the fuel mixture to the holding tank when the mixture fluid therein is extracted to a predetermined low level.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
155 words
A fuel producing system for a solid/liquid mixture, said system comprising a mixing reservoir, said mixing reservoir having a first inlet for receiving a combustible liquid fuel, a second inlet for receiving a solid fuel pulverized to a mixable state with said liquid fuel means for mixing said liquid and pulverized solid fuels in said reservoir, quantitative control means associated with said mixing reservoir to measure predetermined amounts of said liquid and solid fuels delivered therein, a holding reservoir for receiving a solid/liquid fuel mixture from an output conduit of said mixing reservoir, pump means in said output conduit, first control means to shut off the flow of said fuel mixture to said holding reservoir to permit the mixing of further fuel mixture in said mixing reservoir, and second control means to initiate the flow of said fuel mixture to said holding tank when the mixture fluid therein is extracted to a predetermined low level.
Claim 2
Dependent Claim
155 words
A fuel producing system for a solid/liquid mixture, said system comprising a mixing reservoir, said mixing reservoir having a first inlet for receiving a combustible liquid fuel, a second inlet for receiving a solid fuel pulverized to a mixable state with said liquid fuel means for mixing said liquid and pulverized solid fuels in said reservoir, quantitative control means associated with said mixing reservoir to measure predetermined amounts of said liquid and solid fuels delivered therein, a holding reservoir for receiving a solid/liquid fuel mixture from an output conduit of said mixing reservoir, pump means in said output conduit, first control means to shut off the flow of said fuel mixture to said holding reservoir to permit the mixing of further fuel mixture in said mixing reservoir, and second control means to initiate the flow of said fuel mixture to said holding tank when the mixture fluid therein is extracted to a predetermined low level.
Claim 3
Dependent Claim
64 words
A system as claimed in claim 1 wherein said quantitative control means comprises level control sensors to signal the delivery of said fuel at said first or second inlet and to detect a delivered volume of each said fuel to signal the termination of said delivery whereby predetermined amounts of said fuel from said first and second inlets are delivered to said mixing reservoir.
Claim 4
Dependent Claim
61 words
A system as claimed in claim 1 or 2 wherein a recirculation loop is provided with said holding reservoir, said recirculation loop including said pump means and having a control valve operable by said first and second control means to recirculate said fuel mixture in said holding reservoir when the flow of said mixture from said mixing reservoir is shut off.
Claim 5
Dependent Claim
55 words
A system as claimed in claim 3 wherein said first control means is a low level control sensor secured to said holding reservoir to sense a low level of said mixture therein, said second control means being a high level sensor secured to said holding reservoir to sense a high level of said mixture therein.
Claim 6
Dependent Claim
32 words
A system as claimed in claim 1 wherein said quantitative control means is a weight sensor to sense said predetermined amounts of said liquid and solid fuels delivered to said mixing eservoir.
