Abstract
Abstract Fuel delivery display and control system having a dot-matrix panel on which normally a first message is indicated but when a nozzle is taken up for fuel delivery, the first message is replaced with a second message with scrolling for confirmation of no faults in the display elements whereupon the panel displays delivery information consisting of a unit volume price, a delivered fuel volume and a total price to be paid. If necessary, in advance of taking up the nozzle, a switch can be manually actuated so that the delivered fuel volume only is indicated on the panel.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
359 words
A fuel delivery display and control system for a fuel dispensing apparatus comprising: a dot matrix display panel having a plurality of elements operable to be energized to display numerals and letters of the alphabet; first memory means for storing a first message and for feeding signals representing said first message to said display panel; second memory means for storing a second message and for feeding signals representing said second message to said display panel; fuel delivery information means operable to provide signals representing fuel volume and price information relating to fuel dispensed by the fuel dispensing apparatus and for feeding said latter signals to said display panel; first switch means operable to provide a fuel take-up signal and a fuel hang-up signal; clock means operably connected to said first switch means for generating a signal to cause display of said fuel volume and price information on said display panel by said fuel delivery information means to be switched over to display of said first message on said display panel by said first memory means upon expiration of a predetermined period of time after said first switch means has switched to provide said hang-up signal; second switch means operably connected to said first and second memory means and to said first switch means and operable to switch display of said first message on said display panel by said first memory means to display of said second message on said display panel by said second memory means upon receiving a take-up signal from said first switch means, said second switching means being also connected to said fuel delivery information means and operable to subsequently switch display of said second message on said display panel by said second memory means to display of said fuel volume and price information on said display panel by said fuel delivery information means such that said fuel volume and price information is displayed on said display panel during dispensing of fuel by the fuel dispensing apparatus, whereby said first and second messages and said fuel volume and price information are sequentially and automatically displaced on said display panel during operation of the fuel dispensing apparatus.
Claim 2
Dependent Claim
359 words
A fuel delivery display and control system for a fuel dispensing apparatus comprising: a dot matrix display panel having a plurality of elements operable to be energized to display numerals and letters of the alphabet; first memory means for storing a first message and for feeding signals representing said first message to said display panel; second memory means for storing a second message and for feeding signals representing said second message to said display panel; fuel delivery information means operable to provide signals representing fuel volume and price information relating to fuel dispensed by the fuel dispensing apparatus and for feeding said latter signals to said display panel; first switch means operable to provide a fuel take-up signal and a fuel hang-up signal; clock means operably connected to said first switch means for generating a signal to cause display of said fuel volume and price information on said display panel by said fuel delivery information means to be switched over to display of said first message on said display panel by said first memory means upon expiration of a predetermined period of time after said first switch means has switched to provide said hang-up signal; second switch means operably connected to said first and second memory means and to said first switch means and operable to switch display of said first message on said display panel by said first memory means to display of said second message on said display panel by said second memory means upon receiving a take-up signal from said first switch means, said second switching means being also connected to said fuel delivery information means and operable to subsequently switch display of said second message on said display panel by said second memory means to display of said fuel volume and price information on said display panel by said fuel delivery information means such that said fuel volume and price information is displayed on said display panel during dispensing of fuel by the fuel dispensing apparatus, whereby said first and second messages and said fuel volume and price information are sequentially and automatically displaced on said display panel during operation of the fuel dispensing apparatus.
Claim 3
Dependent Claim
97 words
A fuel delivery display and control system according to claim 1, wherein the fuel dispensing apparatus comprises a dispensing nozzle which is manually operable to be mounted in a mounted position on a nozzle support means and to be manually removed from said mounted position on said support means to dispense fuel, said first switch means comprising a switch part actuated by said nozzle as the latter is placed in said mounted position to provide said hang-up signal and actuated by said nozzle as the latter is removed from said mounted position to provide said take-up signal.
Claim 4
Dependent Claim
125 words
A fuel delivery display and control system according to claim 2, wherein said fuel delivery information means stores a unit volume price and is operable to calculate and deliver signals representing the total fuel volume delivered and the total calculated price for said total fuel volume delivered to said display panel, said second switching means being operable to actuate said display panel to reset said displayed total fuel volume and said displayed total calculated price to zero when said first switch means sends its take-up signal, whereby the total fuel volume delivered and the total calculated price of the prior dispensing operation is erased and reset to zero when said nozzle is taken up and removed from said mounted position on said nozzle support means.
Claim 5
Dependent Claim
59 words
A fuel delivery display and control system according to claim 1, wherein said display panel comprises a plurality of horizontal rows and a plurality of vertical columns of dot matrixes which define a display screen, said display panel being operable to display said first and second messages so that said first and second messages repeatedly move along said screen.
Claim 6
Dependent Claim
45 words
A fuel delivery display and control system according to claim 4, wherein said second message is represented by at least one column of dot matrixes such that when said column moves horizontally across said screen, defects in any of said dot matrixes will be indicated.
Claim 7
Dependent Claim
45 words
A fuel delivery display and control system according to claim 4, wherein said second message is represented by at least one row of dot matrixes such that when said row moves vertically across said screen, defects in any of said dot matrixes will be indicated.
Claim 8
Dependent Claim
39 words
A fuel delivery display and control system according to claim 1, wherein said fuel delivery information means comprises a manually operated switch to switch off delivery of signals representing said fuel volume and price information to said display panel.
Claim 9
Dependent Claim
94 words
A fuel delivery display and control system according to claim 1, wherein said display panel comprises a first portion and a second portion, said display panel having manually actuated switch means to selectively switch over to utilize either said first portion, said second portion, or both said first and second portions, whereby the entire display panel is utilized for display and when there is a defect in a dot matrix in the display panel, said manually actuated switch means switches over to effect display only in that portion which does not have said defect.
Claim 10
Dependent Claim
25 words
A fuel delivery display and control system according to claim 8, wherein said first and second portions each represent one half of the display panel.
Claim 11
Dependent Claim
47 words
A fuel delivery display and control system according to claim 1, wherein said second switching means comprises a manually actuated switch element for switching over display of said first message on said display panel to display of said fuel volume and price information on said display panel.
