Controller for fuel dispenser
First Claim
1. A controller for fuel dispenser for use in facilitating and accurately determining the quantity of fuel being dispensed, comprising, a base member, a pulser means supported by said base member, computer means operatively associated with the said pulser means and responsive to signals generated by the pulser means for processing data relative to the dispensing of fuel, said pulser means including an encoder disc mounted for revolving in two directions in response to the flow of fuel being dispensed or monentarily drawn within the dispenser, said disc including rows of detecting means for providing sensing of the quantity and direction of flow of the fuel being dispensed, said rows of detecting means including a series of rows of slots formed through the said encoder disc and useful for effecting sensing of the rates of flow of fuel being dispensed and the direction of fuel flow, said pulser means including sensor means responsive to the turning of the disc and generating electrical signals in response thereto and transferring said signals to the computer means for processing, wherein one row of the slots of the encoder disc cooperating with the sensor means for signaling a detection of the rate of quantity of fuel being dispensed to a first limit, and another row of slots of the encoder disc cooperating with the sensor means and provided for signaling and detecting the rates of flow of fuel in excess of the said first limit, and another row of slots of the encoder disc provided for determining the discharging and retracting of dispensing and flowing fuel, and display means operatively associated with the said computer means for displaying the processed data.

Abstract
In a computer controller for fuel dispensing including a base member, a pulser member supported by the base member and capable of detecting the various increments of fuel quantity being dispensed in addition to deductions therefrom, the signals from the pulser being transmitted to a computer, the computer processing the signals for delivery to a display assembly, and disclosure of the processed information upon liquid crystal displays readily available for view by the customer; a junction box mounted upon the base member, the junction box being completely sealed for exhibiting explosion proof attributes to prevent ignition from sparking of the associated electrical wires or thermal heating of associated electrical components, contained therein and precluding an incident ignition of the external ambient fuel vapors, a computer housing mounted upon the junction box and incorporating the various intrinsically safe circuit boards comprising the computer, and the display assemblies either connecting upon the computer housing or being portable in installation for suspension upon the front of the existing dispenser in converting it from the mechanical actuation type to an electronic computer controlled fuel dispenser.
