Abstract
Abstract In apparatus for dispensing any selected one of a plurality of blends of liquid motor fuels of different octane ratings or numbers, or in the alternative either motor fuel alone, a dual control valve is used to govern the flow of the two fuels to the dispensing nozzle. Each time any one of the blends is manually selected for dispensing, the dual control valve is automatically adjusted (by means of a biasing arrangement) to open wide the higher octane fuel portion of the dual valve and to close completely the lower octane fuel portion of the dual valve.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
79 words
In apparatus for the delivery of a selected one of a plurality of different blends of two liquid motor fuels of different octane numbers, means for selecting a blend of liquids to be delivered, means responsive to the selection made for automatically controlling the proportioning of the liquids delivered, and means for injecting a substantially fixed quantity of the higher octane fuel into a delivery of a blend oF liquids whenever the blend selection is changed for such delivery.
Claim 2
Dependent Claim
79 words
In apparatus for the delivery of a selected one of a plurality of different blends of two liquid motor fuels of different octane numbers, means for selecting a blend of liquids to be delivered, means responsive to the selection made for automatically controlling the proportioning of the liquids delivered, and means for injecting a substantially fixed quantity of the higher octane fuel into a delivery of a blend oF liquids whenever the blend selection is changed for such delivery.
Claim 3
Dependent Claim
35 words
Combination according to claim 1, wherein the higher octane fuel if injected is injected into the initial portion of the blend delivery, before the automatic control of the proportioning reaches its equilibrium point of operation.
Claim 4
Dependent Claim
49 words
Combination of claim 1, wherein the second-mentioned means includes valves individually controlling the deliveries of said liquids, and wherein the third-mentioned means comprises means for yieldably urging said valves toward positions such as to effect delivery of only the higher octane fuel during the initial part of the delivery.
Claim 5
Dependent Claim
32 words
Combination set forth in claim 3, wherein the urging means is effective to urge said valves toward the said positions upon the operation of the blend selecting means to select a blend.
Claim 6
Dependent Claim
37 words
Combination set forth in claim 3, wherein the urging means concurrently urges the valve for the higher octane fuel to a fully open position and the valve for the lower octane fuel to a fully closed position.
Claim 7
Dependent Claim
26 words
Combination set forth in claim 3, wherein the urging means is overcome by the automatic controlling means upon the actual commencement of a delivery of liquid.
Claim 8
Dependent Claim
84 words
Apparatus for the simultaneous delivery of two liquid motor fuels having different octane numbers, comprising individually means metering the deliveries of said liquids, valves individually controlling the deliveries of said liquids, means operated by said metering means to concurrently control said valves to effect the delivery of said liquids in substantially a predetermined ratio, and means for urging said valves toward positions such as to initially effect the delivery of only the higher octane fuel whenever said predetermined ratio is changed for a delivery.
Claim 9
Dependent Claim
84 words
Apparatus for the simultaneous delivery of two liquid motor fuels having different octane numbers, comprising individually means metering the deliveries of said liquids, valves individually controlling the deliveries of said liquids, means operated by said metering means to concurrently control said valves to effect the delivery of said liquids in substantially a predetermined ratio, and means for urging said valves toward positions such as to initially effect the delivery of only the higher octane fuel whenever said predetermined ratio is changed for a delivery.
Claim 10
Dependent Claim
29 words
Apparatus according to claim 7, wherein the last-mentioned means urges the valve for the higher octane fuel fully open and the valve for the lower octane fuel fully closed.
Claim 11
Dependent Claim
41 words
Apparatus defined in claim 7, wherein the last-mentioned means urges said valves toward said positions at the beginning of a dispensing operation, the urging being overcome by the second-mentioned means upon the delivery of liquid through one of the metering means.
Claim 12
Dependent Claim
81 words
In apparatus for the delivery of a selected one of a plurality of different blends of two liquid motor fuels of different octane numbers, means for selecting a blend of liquids to be delivered, means responsive to the selection made for automatically controlling the proportioning of the liquids delivered, and means for injecting a substantially fixed quantity of a certain one of said liquids into a delivery of a blend of liquids whenever the blend selection is changed for such delivery.
Claim 13
Dependent Claim
81 words
In apparatus for the delivery of a selected one of a plurality of different blends of two liquid motor fuels of different octane numbers, means for selecting a blend of liquids to be delivered, means responsive to the selection made for automatically controlling the proportioning of the liquids delivered, and means for injecting a substantially fixed quantity of a certain one of said liquids into a delivery of a blend of liquids whenever the blend selection is changed for such delivery.
Claim 14
Dependent Claim
86 words
Apparatus for the simultaneous delivery of two liquid motor fuels having different octane numbers, comprising individual means metering the deliveries of said liquids, valves individually controlling the deliveries of said liquids, means operated by said metering means to concurrently control said valves to effect the delivery of said liquids in substantially a predetermined ratio, and means for urging said valves toward positions such as to initially effect the delivery of only a certain one of said liquids whenever said predetermined ratio is changed for a delivery.
Claim 15
Dependent Claim
86 words
Apparatus for the simultaneous delivery of two liquid motor fuels having different octane numbers, comprising individual means metering the deliveries of said liquids, valves individually controlling the deliveries of said liquids, means operated by said metering means to concurrently control said valves to effect the delivery of said liquids in substantially a predetermined ratio, and means for urging said valves toward positions such as to initially effect the delivery of only a certain one of said liquids whenever said predetermined ratio is changed for a delivery.
