Abstract
Abstract An apparatus for dispensing a selected grade of motor fuel (each grade having a different octane rating) has an array of operating pushbuttons a selected one of which may be actuated (the selection being made according to the grade of fuel desired) to start the dispensing operation. Upon the actuation of a pushbutton, certain instrumentalities in the apparatus are energized or released to (among other things) select gearing in the apparatus appropriate to the grade selected, reset the counter or register to zero, set a control valve to a predetermined position, and start up the pump to cause the dispensing of fuel to begin. All of these functions are performed automatically, i.e., without any further human intervention, once the pushbutton has been actuated. Upon the termination of the actual dispensing, electrical instrumentalities are automatically activated to carry out certain resetting operations, prior to the next dispensing operation. The dispensing apparatus is particularly suitable for a self-service type of operation.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
188 words
In apparatus for the simultaneous delivery of two liquids in any one of a plurality of preestablished ratios, metering means providing a first output corresponding to the total delivery of said liquids, a variator receiving said output and adjustable to provide a second output corresponding to the amount of said total delivery multiplied by a base price per unit, a settable gear mechanism also receiving said first output and providing a third output corresponding to the amount of said total delivery multiplied by an incremental price per unit which depends upon the particulaR one of said preestablished ratios selected for delivery, means adding said second and third outputs to provide an indication of total price of said total delivery, a plurality of manually-operable pushbuttons one for each of said preestablished ratios, means operating automatically, in response to the operation of a selected one of said pushbuttons, for setting said gear mechanism to a position depending upon which particular pushbutton has been operated, valve means controlling the delivery of said liquids, and controlling means for said valve means to effect delivery of said liquids in substantially a predetermined ratio.
Claim 2
Dependent Claim
188 words
In apparatus for the simultaneous delivery of two liquids in any one of a plurality of preestablished ratios, metering means providing a first output corresponding to the total delivery of said liquids, a variator receiving said output and adjustable to provide a second output corresponding to the amount of said total delivery multiplied by a base price per unit, a settable gear mechanism also receiving said first output and providing a third output corresponding to the amount of said total delivery multiplied by an incremental price per unit which depends upon the particulaR one of said preestablished ratios selected for delivery, means adding said second and third outputs to provide an indication of total price of said total delivery, a plurality of manually-operable pushbuttons one for each of said preestablished ratios, means operating automatically, in response to the operation of a selected one of said pushbuttons, for setting said gear mechanism to a position depending upon which particular pushbutton has been operated, valve means controlling the delivery of said liquids, and controlling means for said valve means to effect delivery of said liquids in substantially a predetermined ratio.
Claim 3
Dependent Claim
242 words
In apparatus for the simultaneous delivery of two liquids in any one of a plurality of preestablished ratios, metering means providing individual outputs corresponding to the delivery of said first and second liquids and also providing a first output corresponding to the total delivery of said liquids, a variator receiving said first output and adjustable to provide a second output corresponding to the amount of said total delivery multiplied by a base price per unit, a settable gear mechanism also receiving said first output and providing a third output corresponding to the amount of said total delivery multiplied by an incremental price per unit which depends upon the particular one of said preestablished ratios selected for delivery, means adding said second and third outputs to provide an indication of total price of said total delivery, a plurality of manually-operable pushbuttons one for each of said preestablished ratios, first means operating automatically, in response to the operation of a selected one of said pushbuttons, for setting said gear mechanism to a position depending upon which particular pushbutton has been operated, valves individually controlling the deliveries of said liquids, adjustable means operated by said metering means and simultaneously controlling said valves to effect the delivery of said liquids in substantially a predetermined ratio, and second means operating automatically, in response to the operation of said one selected pushbutton, for adjusting said adjustable means to a position depending upon which particular pushbutton has been operated.
Claim 4
Dependent Claim
242 words
In apparatus for the simultaneous delivery of two liquids in any one of a plurality of preestablished ratios, metering means providing individual outputs corresponding to the delivery of said first and second liquids and also providing a first output corresponding to the total delivery of said liquids, a variator receiving said first output and adjustable to provide a second output corresponding to the amount of said total delivery multiplied by a base price per unit, a settable gear mechanism also receiving said first output and providing a third output corresponding to the amount of said total delivery multiplied by an incremental price per unit which depends upon the particular one of said preestablished ratios selected for delivery, means adding said second and third outputs to provide an indication of total price of said total delivery, a plurality of manually-operable pushbuttons one for each of said preestablished ratios, first means operating automatically, in response to the operation of a selected one of said pushbuttons, for setting said gear mechanism to a position depending upon which particular pushbutton has been operated, valves individually controlling the deliveries of said liquids, adjustable means operated by said metering means and simultaneously controlling said valves to effect the delivery of said liquids in substantially a predetermined ratio, and second means operating automatically, in response to the operation of said one selected pushbutton, for adjusting said adjustable means to a position depending upon which particular pushbutton has been operated.
