Abstract
Abstract An emulsifying system for mixing accurate ratios of two or more liquids to form an emulsion. The liquids are preferably, but not exclusively, water and oil. A supply circuit delivers accurate mixtures of the two or more liquids. An emulsifier emulsifies the mixture to form an emulsion. A container stores a quantity of the emulsion that may vary between predetermined limits and an output circuit is provided to draw the emulsion from the storage container. The emulsion storage container permits the supply of the mixture and the emulsion to the storage container at a rate independent of the rate at which the emulsion is drawn from the output circuit.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
142 words
An emulsifying system for mixing accurate ratios of two or more liquids to form an emulsion, said system comprising means for supplying an accurate mixture of said two or more liquids, an emulsifying device to emulsify said mixture into an emulsion, emulsion storage means for storing a quantity of said emulsion that may vary between predetermined limits, an output circuit to draw said emulsion from said emulsion storage means, a recirculating circuit connected at said output circuit and having a recirculating pump to recirculate said emulsion to said emulsifying device where said emulsion is regenerated and returned to said storage means whereby said emulsion in said storage means is maintained in a usable state, said emulsion storage means permitting the supply of said mixture to it at a rate independent of the rate at which said emulsion is drawn from said output.
Claim 2
Dependent Claim
142 words
An emulsifying system for mixing accurate ratios of two or more liquids to form an emulsion, said system comprising means for supplying an accurate mixture of said two or more liquids, an emulsifying device to emulsify said mixture into an emulsion, emulsion storage means for storing a quantity of said emulsion that may vary between predetermined limits, an output circuit to draw said emulsion from said emulsion storage means, a recirculating circuit connected at said output circuit and having a recirculating pump to recirculate said emulsion to said emulsifying device where said emulsion is regenerated and returned to said storage means whereby said emulsion in said storage means is maintained in a usable state, said emulsion storage means permitting the supply of said mixture to it at a rate independent of the rate at which said emulsion is drawn from said output.
Claim 3
Dependent Claim
20 words
A system as claimed in claim 1 wherein said emulsion is a water/oil emulsion for use as a combustible fuel.
Claim 4
Dependent Claim
138 words
A system as claimed in claim 3 wherein said means for supplying an accurate mixture comprises injection means fed by a regulated water and oil supply to provide said accurate mixture of said water and oil, said injection means is an injector device having a water flow inlet and an oil flow inlet connected respectively to said water and oil regulated supplies, conduit means to release water and oil flows from said inlets to mix in said injector device, said regulated supplies being pressure regulated supplies, said pressure regulated supplies each have a pressure regulating device and a flow restriction means located downstream of said pressure regulating device, said flow restriction means controlling the flow rate of said water and oil supplies for delivery to said water flow inlet and oil flow inlet, respectively, of said injection device.
Claim 5
Dependent Claim
115 words
A system as claimed in claim 3, wherein said water/oil emulsion is drawn into said recirculating circuit by said recirculating pump, said emulsifying device being connected between said recirculating pump and said storage means, said storage means being provided with volume control means to control the flow of said water/oil emulsion from said injection means to said storage means, said storage means further comprising temperature control means to maintain said water/oil emulsion at a desired temperature, input means connected to said storage means to feed back water/oil emulsion from a burner, and wherein said output circuit is connected to said burner whereby said burner draws said water/oil emulsion from said storage means when in operation.
Claim 6
Dependent Claim
36 words
A system as claimed in claim 1, wherein valve means is provided downstream of said means for supplying an accurate mixture to isolate said storage means from pressure from said means for supplying said accurate mixture.
Claim 7
Dependent Claim
15 words
A system as claimed in claim 1, wherein said storage means is vented to atmosphere.
Claim 8
Independent Claim
113 words
A method of mixing accurate ratios of two or more liquids and forming a stable emulsion therefrom comprising the steps of: (i) mixing said two or more liquids in an accurate proportion to form a mixture, (ii) producing an emulsion from said mixture, (iii) supplying said emulsion to a storage means to maintain the level emulsion in said storage means between predetermined limits, (iv) withdrawing said emulsion from said storage means at a rate independent of the rate at which said emulsion is supplied to said storage means, and (v) feeding said emulsion from said storage means to an emulsifying device where said emulsion is regenerated and fed back to said storage means.
Claim 9
Independent Claim
