Other objects will be in part obvious and in part pointed out more in detail hereinafter.
A better understanding of the invention will be obtained from the following detailed description and the accompanying drawings of an illustrative application of the invention.
BRIEF DESCRIPTION OF THE DRAWINGS In the drawings:
FlGs. 1A through 1D inclusively are collectively a diagrammatic view. partly broken away, of a fluid delivery control and registration system incorporating an embodiment of the present invention.
DESCRIPTION OF THE PREFERRED EMBODIMENT Referring now to the drawings in detail, a fluid deliv ery control and registration system incorporating an embodiment of the present invention is provided for controlling and registering the fluid deliveries from twelve generally conventional fuel pumps 10. Only one fuel pump (i.e., Pump 1) and only the corresponding pump interlock circuit 12 and the corresponding pump interconnect circuit 14 are shown in the drawing for convenience.
The fluid delivery control and registration system comprises a plurality of manually operable controls and a display register 16 for selectively displaying the cost and volume of the fuel deliveries from the twelve pumps and the total volume and total cost of each of three grades of fuel, herein designated grades A, B and c, delivered from the twelve pumps. The display register 16 and the manually operable controls are preferably provided on a single console and the console is preferably located to permit a console operator to view a dispensing operation at each of the pumps as well as to control and register each delivery. The system has primary utility in providing for self-service delivery fuel and such that each customer can handle his own fuel delivery after appropriate authorization is given by the console operator and then pay the console operator for the fuel delivery.
The system comprises a timing circuit 18 for sequentially generating individual and binary timing signals for properly coordinating and/or sychronizing certain logic processing functions of the system. The timing circuit 18 comprises a l MHZ clock 20 which steps a timing pulse ring counter 22 for sequentially generating timing pulses TPO through TP -8 in corresponding output leads of the timing counter 22. The TP-8 timing pulse is similarly employed to step a digit ring counter 24 for sequentiaily generating digit pulses D-l through D-6 in corresponding output leads of the digit counter 24. And the D-6 pulse is used to step a pump selector ring counter 26 for sequentially generating binary pump address signals. A decoder 30 is operated by the binary address signals for sequentially generating pump pulses P-l through Pl2 in corresponding output leads of the decoder 30. The TP-8 timing pulse is also connected via a D-6 pulse controlled gate 31 for stepping a memory address counter 32only five steps for each sixdigit pulse cycle of the digit counter 24for sequentially addressing the memory digits of memories 34 (which preferably have 64-digits but which use only 60- digits in the shown embodiment) of an A memory circuit 36 and an identical B memory circuit 38. A suitable reset circuit 40 is operated by the binary memory address output of the memory address counter 32 to reset the counter 22, 24, 26 and 32 at the completion of each 60 digit cycle of the memory address-and therefore at the completion of twelve full digit cycles of the digit counter 24 and one full cycle of the decoder 30and to thereupon initiate a succeeding digit cycle and synchronize the counters.
Thus, the timing circuit provides consecutive Pl through P-l2 pump pulses and a synchronized binary output signal designating the pump. During each pump pulse, six sequential digit pulses D-l through D-6 are provided and for each digit pulse nine sequential timing pulses TP-O through TP-8 are provided.
A pump selector 43 comprising a line of twelve pump push buttons 44 is provided for individually registering with the display register 16 the cost and/or volume of a fuel delivery from each pump for individually determining the memory status for each pump and for individually clearing the pump memories. Each selector 'button 44 is connected to the corresponding P-l through P-l2 pump lead of the decoder 30. The pump selector push buttons 44 are mechanically interlocked so that only one push button may be depressed at a time and such that a single P-l through P-l2 pulse is transmitted to a pump selector output 45 in accordance with the push button 44 which is depressed.
A presettable grade selector 50 is provided for generating synchronized grade pulses in its three output leads representing the grade of each pump. The grade selector 50 has twelve input leads connected to the twelve P-l through P-12 pump leads and a suitable buffer diode 56 between each input lead and a terminal 57. The terminals are adapted to be selectively connected to the grade output terminals 58 for presetting the grade selector in accordance with the grade delivered from each pump. Although pumps 1-5 are shown connected to the grade A terminal, pumps 6-8 are connected to the grade B terminal and pumps 9-12 are connected to grade C terminal, the connections would be made as appropriate for each of the 12 pumps.
A line of 12 pump authorization buttons 60 are provided for authorizing fuel deliveries from the 12 pumps. An authorization request button 62 is also provided at each pump for requesting authorization of a fuel delivery. A request authorization signal from the push button 62 sets a request authorization flip-flop 64. The flip-flop 64 in combination with a suitable flasher 66 (used for all 12 pumps) thereupon operate, via gates 68 and 70 to flash a push button lamp (not shown) at the corresponding authorization push button on and off, and thereby signal the console operator that a fuel delivery is requested. The corresponding authorization button 60 is connected, via an AND gate 72, to set an authorization flip-flop 74 and thereby provide an authorization signal transmitted via gate 76 to authorize the delivery of fuel from the corresponding fuel pump 10. The authorization signal is also applied to the gate 70 to hold the push button lamp on and thereby indicate that a delivery has been authorized. The pump interlock circuit 12 also employs a manual override switch 80 for maintaining the corresponding pump active, for example for attendant made deliveries. Also, an emergency push button 82 is connected to the gate 76 for deenergizing the pump at any time.
[n a conventional manner, the pump 10 has an operating handle 90 mounted adjacent the usual fuel delivery nozzle receptacle so that the handle 90 must be placed in its vertical of of position before the delivery nozzle 91 can be returned to its receptacle at the end of a fuel delivery and cannot be moved to its horizontal or on position until after the nozzle 91 is removed from its storage receptacle. Upon authorization, power is supplied to a suitable electric reset 92 of the pump such that when the handle 90 is placed in its on" or horizontal position, the electric reset 92 is energized to reset the volume and cost registers 93, 94 of the pump computer 96. After the registers 93, 94 are reset to zero, power is supplied to the fuel delivery pump motor 98 to condition the pump 10 for delivering fuel. A status signal is thereupon transmitted to a gate 104 to generate a memory clear signal in the memory clear lead l06-for clearing the corresponding pump memory section of the appropriate memory circuit 36, 38. The gate 104 is also connected to a pulse control gate 108 for transmitting cost pulses from a pump pulse generator 110 via lead 112 to a pulse scanner 114 of a scanning circuit 116. Accordingly, cost pulses are transmitted to the scanner 114 only while the pump 10 is active for delivering fuel and pulses cannot be transtor is also reset with the cost register 94 so that the pulse timing remains accurate.
At the completion of a delivery when the handle 90 is returned to its vertical or off" position, or when the pump is deactivated by the emergency push button 82, a pulse is generated by a single shot to reset the flip-flops 64 and 74 and thereby deactive the pump and turn off the pump authorization button lamp. The pulse generated by the single shot 120 also operates to set a first control flip-flop 122 and, if the flip-flop 122 is already set, to set, via gate 124, a second control flip-flop 126. The flip-flop 122 is connected via a lead 123 to apply a memory select signal to a corresponding pump input ofa memory select scanner 125. The flip-flop 122 is also connected via a gate to a lamp A scanner 132 to light (as here-inafter described) a lamp (not shown) associated with a memory A button 133 to indicate that the A memory section for the corresponding pump is in use. Similarly, the flip-flop 126 is connected to a lamp B scanner 134 to light (as hereinafter described) a lamp (not shown) associated with a memory B button 135 and thereby indicate that the B memory section for corresponding pump is in use. The flip-flops 122, 126 are also connected (a) via a gate to the gate 72 to prevent a succeeding authorization when both available memory sections are in use and (b) via a gate 141 and lead 142 to selectively energize a lamp (not shown) associated with the corresponding pump selector button 44 when either or both of the memory sections are in use.
The A and B memory sections for each pump may be individually cleared (upon the commencement of the succeeding delivery with the memory clear signal transmitted via lead 106) by simultaneously depressing the appropriate memory button 133, 135 and a clear button 143. As a result, a gate 144 is timely pulsed by the pump selector output pulse to transmit a clear pulse via a corresponding memory gate 145, 146 to the A and B memory clear decoders 149, respectively.
The scanners 132, 134 and the decoders 149 and 150 are operated by the binary pump address signals such that (a) the pump lamp signals from each pump are transmitted to operate the lamps when the corresponding pump selector button is depressed and (b) the clear pulses are transmitted to clear the memory sections for a pump when the corresponding pump selector button is depressed. More particularly, when a pump selector button is depressed, the memory A clear signal is transmitted to the corresponding pump interlock circuit 12 to set a memory A clear flip-flop and the memory B clear signal is transmitted to reset the second control flip-flop 126. The flip-flop 160 is connected to gate 130 to turn off the memory A push button lamp. The first control flip-flop 122 is not, however, reset if the pump is then active and a gate 164 is connected for transmitting a reset signal for resetting the first control flip-flop 122 when the pump is deactivated and for also resetting the flip-flop 160. The delayed reset of the first control flip-flop 122 is provided for preventing switching memory circuits by switching the memory select signal in the lead 123 during the delivery of fuel.
The output leads from the A and B lamp scanners 132, 134 are connected to gates which are pulsed by the pump selector output pulse. Thus, for example, when the pump 1 selector button 44 is depressed and a memory A lamp signal is transmitted to the scanner 132 from pump 1, a flip-flop 172 is set to energize the lamp (not shown) associated with the memory A push button 133. When the lamp signal is terminated upon the setting of the flip-flop 160, the pump selector output pulse is transmitted via a gate 174 to reset the flipflop 172 and deenergize the memory A push button lamp. An identical system is provided for energizing and deenergizing the memory B push button lamp via the scanner 134.
The cost pulses from the active pumps are transmitted to the pulse scanner 114 by the corresponding cost pulse leads 112. Similarly, the memory clear signal for each pump is transmitted to a memory clear scanner 107 via a corresponding pump lead 106 and the memory select signals are transmitted via respective memory select leads 123 to a memory select scanner 125.
The scanning circuit 116 provides for sequentially transmitting the cost pulses and control signals received from the pump interlock circuits 12 for proper operation of the A and B memory circuits 36, 38. Also, the cost pulses are transmitted via the scanning circuit 116 for operating a totalizer circuit 190 using an eighteen-digit memory 192 (Le, six-digits for each of the three available fuel grades A, B and C) for accumulating the total cost (in dollars in the shown embodiment) of each fuel grade delivered by all of the pumps connected for delivering that grade.
The scanning circuit 116 employs a l2-digit memory 200 (preferably having l6-digits but using only l2- digits in the present embodiment) which is addressed in synchronism with the scanners 114, 107, and 125 by the binary pump address signals for transmitting and storing each cost pulse and each memory clear signal received from each pump interlock circuit 12 via the pulse scanner 114 and memory clear scanner 107. More particularly during each pump pulse interval any generated cost pulse from the corresponding pump is transmitted through the scanner 114, and then via a gate 202 during the succeeding TP-2 timing pulse of the D-1 digit pulse to temporarily set a flip-flop 204. The flip-flop 204 thereupon transmits a cost pulse signal via a gate 205 and either an A memory gate 206 or a B memory gate 207 as an input pulse to the respective memory circuit 36 or 38. The cost pulse signal is also written into the corresponding memory digit by the immediately following TP-6 timing pulse, and the flipflop 204 is then reset by the immediately following timing pulse TP-7. The pulse duration of each cost pulse transmitted to the scanner 114 is substantially longer than a complete scanner cycle such that each cost pulse is operative to set the flip-flop 204 several times during several successive cycles of the scanner 114. However, an output cost pulse signal is transmitted to the appropriate memory circuit 36 or 38 (at timing pulse TP-4 of digit pulse D-l) only once because the stored cost pulse signal in the corresponding memory digit is thereafter operative to make the control gate 205 nonconductive. After the cost pulse signal applied to the scanner 114 terminates, the corresponding memory digit is cleared by the TP-6 write pulse to permit a succeeding cost pulse to be transmitted through the control gate 205. A memory clear signal transmitted to the clear scanner is similarly analyzed and transmitted via identically numbered circuitry to set a flip-flop 210 which transmits an output memory clear signal via either an A memory gate 212 or a B memory gate 214 to the appropriate memory circuit 36 or 38. The output memory clear signal is applied to the appropriate memory circuit during the interval between the TP-4 timing pulse of the D-1 digit pulse and the TP-7 timing pulse of D-6 digit pulse for fully resetting the five corresponding pump digits of the memory circuit whereupon the flip-flop 210 is reset via a gate 218.
The memory select signal from each pump interlock circuit 12 is transmitted during the corresponding pump pulse via the memory select scanner for timely operating the A memory gates 206, 212 or the B memory gates 207, 214. Thus, with the first control flip-flop 122 of the pump interlock circuit 12 in a cleared or reset condition, the A memory gates 206, 212 will be effective to transmit the clear signal to the A memory circuit 36 (for clearing the corresponding five-digit pump memory section of the memory 34) and then transmit succeeding cost pulses to the A memory circuit 36 for accumulating the cost amount of the succeeding fuel delivery. If the first control flip-flop 122 is in its set conditionn, the clear signal and succeeding cost pulses are transmitted to the B memory circuit 38 for similarly clearing the corresponding pump memory section and accumulating the cost amount of the succeeding fuel delivery in the B memory circuit 38.
A bank of gates 217-219 are also timely operated by corresponding grade pulses to transmit the cost pulse signals from the gate 205 to cost division circuits 232-234 for the three available grades. Each division circuit 232-234 transmits an output pulse for each one hundred input pulses (and accordingly are in effect one dollar pulses) via a gate 236 to the totalizer circuit 190.
The cost pulse signals for each pump are transmitted to the selected memory circuit for accumulation of the cost amount of fuel delivered from the pump. The memories 34 are addressed in synchronism with the corresponding cost pulse trains such that the corresponding five-digit memory section of the selected memory 34 will accumulate the cost (up to a maximum of $999.99) of the fuel delivered. More particularly, the cost pulses are supplied to a gate 250 of the selected memory circuit 36, 38 to add a count of one to a BCD counter 252 which has been preset (with timing pulse TP-2 of digit pulse D-l) with the existing digit count of the first digit of the accumulated cost. The count of the counter 252 (i.e., the prior digit count plus one) is then written into the first digit by timing pulse TP-7. Any carry signal from the digit count is added to the succeeding digit. The carry signal from the BCD counter 252 initially sets a flip-flop 253 which then transmits the carry signal via a gate 254 to a second flip-flop 256 at the TP-2 timing pulse of the following timing pulse cycle whereupon the first flip-flop 253 is reset. The carry signal is then transmitted from the flipflop 256 via a gate 258 and the gate 250 to the counter 252 at timing pulse TP-6. The count in the counter 252 is then stored in the memory digit. Thus, each five-digit pump memory section of the memory 34 accumulates the total cost of fuel delivered by the corresponding pump to two decimal places. The five-digit memory 'section for a given pump is selectively cleared by the clear signal transmitted via the gate 212 or 214, as previously explained, upon the commencement of each fuel delivery.
The totalizer circuit comprises an 18-digit memory 192 for storing the total cost amount in dollars of I each available fuel grade delivered by the delivery system. The one dollar cost pulses transmitted via the gate 236 to the totalizer circuit 190 are handled-in exactly the same manner as the l-cent cost pulses are handled in the A and B memory circuits 36, 38--to accumulate the total cost delivered of the three grades of fuel and in the respective six-digit memory sections of the memory 192. The memory 192 is addressed by a memory address circuit 270 which is initially set, during each pump pulse, by the respective grade pulse and is then sequentially stepped by the succeeding TP-8 timing pulses.
The totalizer circuit memory 192 may be manually reset, for example, at the end of the day or at the end of each 8 hour shift after the volume and cost totals are suitably recorded as described, for which purpose a suitable manual reset button 280 is connected to the memory 192 for clearing the memory 192. The reset button 280 is also connected for simultaneously clearing the division circuits 232-234.
The accumulated cost amount of each fuel delivery from each pump can be selectively registered on the display register 16 merely by depressing the corresponding pump selector button 44 and depressing the appropriate memory select button 133, l35'for that delivery. (As the cost amounts of two separate fuel deliveries can be stored in the separate memory circuits 36, 38, the desired delivery cost data can be displayed by depressing the memory select button 133, 135 for the appropriate memory circuit.) The memory select buttons I33, 135 are connected, via control gates 296, 298 respectively, to a bank of A memory data control gates 300 and a bank of B memory data control gates 302 for selectively connecting the BCD memory outputs via a cost data bus 306 and a cost/volume selector 308 to BCD digit storage registers 310 of the display register 16. The BCD digit registers 310 are sequentially loaded via gates 314 by the digit pulses D-l through D-6 of the selected pump pulse. Decoder driver circuits 320 provide for operating digit display registers 322 in accordance with the BCD outputs of the digit storage registers 310 such that the accumulated cost for the selected pump delivery is displayed by the display registers 322. The display registers may, for example be 7- bar, FIG. 8 type display tubes manufactured by Radio Corporation Of America under the trademark NUMl- TRON.
A decimal point driver 326 is provided for energizing the decimal point 328 of the second order digit display 322 such that the register 16 will properly display the cost amount of the delivery to two decimal places. Also, as the cost is only accumulated to five places in the memories 34, the sixth or highest order digit display 322 is held deenergized or blanked by a signal from an inverter 330 applied to the sixth place decoder driver 320. The fifth or next highest order digit display decoder driver 320 may also be similarly connected as shown in dotted lines where a four place cost display (i.e., providing a maximum cost display of $99.99) is sufficient.
The volume amount of the selected fuel delivery (which corresponds to the selected cost amount) may be selectively registered with the register 16 by additionally depressing and holding depressed a volume select button 340. The volume select button 340 is conand load the volume computer 350. The clear and load pulse so generated is transmitted via a control gate 354 to (a) clear six BCD decade counters 360 of a volume counting section 362, (b) clear a simulated cost computer 364 and (c) reset three price control flip-flops 365-367 of the cost computer 364. At the same time, the selected BCD cost data transmitted via the cost data bus 306 is sequentially loaded into the first five place BCD cost registers 370 by means of the digit pulses D1 through D5 applied to the registers via the control gates 372. The highest order register 370 is maintained disconnected from the cost data bus 306 by a bank 374 of control gates when computing the volume amount of an individual delivery and, therefore, when a six place storage register is not required. Thus, in effect, the highest place register 370 is then set at binary zero.
The clear and load signal also operates a suitable delay circuit 378 which, after the volume computer 350 is cleared and the registers 370 are loaded, generates a control signal for making the gate 354 nonconductive and for making a gate 382 conductive for supplying clock pulses (which function as simulated volume pulses) via a second control gate 384 to the simulated cost computer 364. The cost computer may, for example be like that disclosed in U.S. Pat. No. 3,696,236 of Crawford M. Kus entitled Computing Device and dated Oct. 3,1972. As more fully described in the U.S. Pat. No. 3,696,236, a bank 390 of three BCD price switches 392 is provided for each of the three available grades of fuel. Each switch bank 390 is preset in accordance with the preestablished unit volume price for the corresponding grade. The switch banks 390 are selectively activated by the application of the clear and load timing pulse and grade timing pulses to the control gates 395-397 which then transmits a pulse for setting one of the flip-flops 365-367 in accordance with the preset fuel grade for the depressed selector button 44 for activating the corresponding price switch bank 390.
The simulated volume pulses passing through the control gate 384 are supplied to the lowest order BCD decade counter 360 of the volume counting section 362 to accumulate a volume count in the volume counting section 362. At the same time, the simulated volume pulses are supplied to the cost computer 364 to accumulate a cost count in a six place BCD cost accumulator 400 of the computer 364. A suitable comparator circuit 402 is connected to the BCD readout leads of the cost registers 370 and to the BCD readout leads of the cost accumulator decades 404 such that when the accumulated cost in the accumulator 400 equals the preset cost in the registers 370, the comparator operates the control gate 384 to terminate the supply of simulated volume pulses to the cost computer 364 and volume accumulator 362. Accordingly, the volume amount accumulated in the volume accumulator 362 exactly corresponds to the cost amount of the selected fuel delivery stored in memory in accordance with the preestablished unit volume price of the fuel grade. The accumulated volume amount is continuously transmitted via banks 410 of digit pulse controlled gates 412 and the cost/volume selector 308 to the display register 16 for displaying the computed volume of the selected fuel delivery.
A totalizer display button 420 and individual fuel grade buttons 421-423 are provided for selectively registering, with the display register 16, the total accumulated cost of each grade of fuel delivered. When the totalizer display button 420 is depressed, the gates 296, 298 are thereupon operated to disconnect the memory select buttons 133, 135 from the corresponding banks 300, 302 of data control gates. Also. the blanking circuit to the display register 16 is deenergized and the decimal point driver 326 is operated to deenergize the second place decimal point 328. (A first place decimal point could be connected as shown in broken lines to be energized to register the total cost amount of the first decimal place, in which event, the division circuits 232-234 would be divide by ten circuits rather than divide by one hundred circuits as shown.) The individual grade buttons 421-423 are suitably mechanically interlocked so that only one button can be depressed at a time. The depressed button supplies a grade timing pulse via a control gate 425 to a bank 427 of BCD data control gates to sequentially supply the digital totalizer cost data for the selected grade via selector 308 to the display register 16 where it is then displayed (up to a maximum of $999,999).
The total volume amount corresponding to the selected cost amount stored in the memory can be selectively registered with the display register 16 by additionally depressing and holding depressed the'volume select button 340. Thereupon, the totalizer cost data for the selected grade is transmitted to the volume computer 350 which then computes the corresponding volume amount in accordance with the transmitted total cost amount and the unit volume price of the selected grade of fuel. In this latter regard, the appropriate price control flip-flop 365-367 is set via the corresponding gate 395-397 by the grade timing pulse transmitted thereto from the depressed grade push button 421-423. The totalizer volume computed in the volume computer 350 is transmitted to the display register 16 for registration with the six register digits 322 (up to a minimum of 999,999 gallons).
