Abstract: The present invention is a variable blending dispenser for fluids, particularly for fuel dispensers. The dispenser controls variable valves according to volumetric data observed by flow meters on input lines to the dispenser, by calculating measuring error as the difference between desired blend ratio and the observed blend ratio calculated from volumes of blend components dispensed. The dispenser successively corrects the settings of the valves after dispensing predetermined volumes, the corrections determined by a volume based PID error function so that the total amount of each blend component is separately and accurately measured while providing the desired blend ratio.

Abstract: A dispenser for delivering different grades of gasoline through a single nozzle at each fueling position, includes a pair of hoses connected to the nozzle, one of which hoses is used for selectively delivering high octane gasoline, and the other of which hoses is for selectively delivering either low octane or mid octane gasoline through the nozzle, whereby a control system is programmed for monitoring the dispensing of low octane gasoline relative to the dispensing of mid octane gasoline, for injecting a sufficient quantity of high octane gasoline through the nozzle at the initiator of a mid octane dispensing cycle for compensating for low octane fuel remaining in the other hose from an immediately prior low octane dispensing cycle relative to a mid octane dispensing cycle.

Abstract: A conversion mechanism for selective conversion of a conventional mechanical fuel pump computer to selectively extend the unit volume price range of the computer while maintaining the rotational speed of the right hand cost and volume counter wheels of the computer within acceptable limits and mathematical correspondence of the volume counter readout with the cost counter readout and the established unit volume price. The conversion mechanism comprises cost and volume drive ratio selector mechanisms and one or more sets of single transfer, double transfer and quadruple transfer right hand cost counter wheels and a decimal point selector mechanism for shifting the decimal point of the unit volume price setting and/or cost counter readout.

Abstract: A conversion mechanism for selective conversion of a conventional mechanical fuel pump computer to selectively extend the unit volume price range of the computer while maintaining the rotational speed of the right hand cost counter wheels of the computer within acceptable limits. The conversion mechanism comprises a cost drive ratio selector mechanism and one or more sets of substitute single transfer and double transfer right hand cost counter wheels and provides for selectively and successively shifting the decimal point of the unit volume price range and cost counter readout and for establishing a cost counter drive ratio for each of the substitute right hand cost counter wheels.

Abstract: Microprocessor controlled flow metering apparatus employs mechanically coupled registers driven by a positive displacement or other flow meter to display fluid volume dispensed during a monitored transaction--and as a cumulative total over time. User adjustable electrical switch decades electrically enter computational scale factor variables such as price per gallon and tax rate.The stored program controlled microprocessor computes all desired output variables (fuel cost, tax)--and outputs the variables in predesignated fields onto a printed ticket (invoice) while controlling printer carriage movement and solenoid actuation. In accordance with varying aspects of the invention, mechanical and software security is provided to ensure proper correlation between customer fluid (e.g., fuel) receipt and billing.

Abstract: Price encoder for delivering pulses corresponding to the price of gasoline or other liquid petroleum products dispensed by a pump. The encoder is removably mounted on the existing mechanical price computer in the pump and includes an input gear for engaging a drive gear on the computer. A pulse generator coupled to the input gear provides pulses at a higher rate than required for the output, and this pulse rate is reduced by a counter to provide a desired number of pulses per unit price. The counter is reset in response to the application of operating power to eliminate errors which might otherwise arise when the pump is reset.

Abstract: An apparatus and method for vending liquid fuel of the type wherein an electrically driven pump is controllably energized in response to a counter adding a credit unit as electrically signalled by a money acceptor. The counter subtracts credit units in response to a primary dispensing switch which is operatively responsive to the dispensing of fuel. In accordance with the present invention, a fail-safe circuit is provided which is electrically connected with the counter, acceptor and primary switch and which is operable for selectively disabling the pump from delivering fuel. A secondary dispensing switch is provided which is operatively responsive to dispensing of fuel and which cooperates with the fail-safe circuit in monitoring the normal sequence of vending steps and responding to abnormality in such normal sequence of steps by precluding delivery of pumped fuel.

Abstract: Draft beer monitoring apparatus in which the amount of beer dispensed is indicated in terms of the sales price, the indicator being controlled by a pair of pulsers operating at different rates associated with the dispensing of a glass or a pitcher of beer. The glass-rate pulser is actuated upon the operation of a switch when the dispensing tap is initially opened. If the tap remains open for a period of time greater than that required to fill a glass, a timer automatically actuates the pitcher-rate pulser instead of the glass-rate pulser.

Abstract: This disclosure is directed to an attachment for a limited range gasoline pump. Many gasoline pumps are limited in price range to $9.99. The apparatus comprises an attachment wherein the number one is located on the face of the pump to extend its range to $19.99, and a flag bearing a dollar sign is placed over the number one. The flag remains in position if the sale is $9.99 or less. If that value is exceeded, the flag is moved to the left to expose the one, keeping the dollar sign correctly located. Movement is controlled by a cam attached to the rotating number wheel which displays the dollar value. This wheel is mounted on a cross shaft. The attachment cooperates with the cross shaft to respond to movement thereof to provide a reset motion when the gasoline pump is reset to zero.
