Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
153 words
In an installation for the remote control of a liquid disperser comprising a main control station, at least one liquid pump having a flow meter and display panel in electrical communication with the main control station and means in electrical communication with said pump for monitoring and controlling the dispensing of liquid, the improvement comprising including a programmable general purpose computer as the monitoring and controlling means wherein the operating program of the computer of the pump is stored in a programmable read only memory (PROM) and wherein said memory comprises in its operating program, for the determination of the volume of liquid and of the sum of money to be paid, two independent sub-routines which cause the central processing unit (CPU) of the computer to carry out the necessary calculations, in two independent sequences from two independent trains of counting a pulses (φ) and (1) from the pulse-generator coupled to the flow-meter.
Claim 2
Dependent Claim
153 words
In an installation for the remote control of a liquid disperser comprising a main control station, at least one liquid pump having a flow meter and display panel in electrical communication with the main control station and means in electrical communication with said pump for monitoring and controlling the dispensing of liquid, the improvement comprising including a programmable general purpose computer as the monitoring and controlling means wherein the operating program of the computer of the pump is stored in a programmable read only memory (PROM) and wherein said memory comprises in its operating program, for the determination of the volume of liquid and of the sum of money to be paid, two independent sub-routines which cause the central processing unit (CPU) of the computer to carry out the necessary calculations, in two independent sequences from two independent trains of counting a pulses (φ) and (1) from the pulse-generator coupled to the flow-meter.
Claim 3
Dependent Claim
54 words
The installation of claim 1, wherein said memory further comprises another sub-routine for having the CPU continuously compare the results from the calculations performed on the two independent trains (φ) and (1) of pulses, and in case of a discrepancy greater than a chosen margin, for having the delivery pump be disabled and stopped.
Claim 4
Dependent Claim
130 words
The installation of claim 1, wherein the computer comprises a random access memory (RAM) for storing and temporarily restoring some of the data provided by the CPU, and wherein the PROM comprises in its operating program sub-routines for having the CPU store in said RAM (area A) the information relative to the quantities and cost of the liquid delivered to a customer and display said information on the display system then, on order from the main station, to transfer said information into another area (area B) of said RAM, re-store them again therein and display them on a further display panel, so that a new customer, the initial recording and displaying areas being now available, can draw liquid from the same pump before the previous customer has paid his bill.
