Abstract: 1389253 Counting apparatus; price & quantity calculations ANTHES IMPERIAL Ltd 31 May 1972 [4 Oct 1971] 25533/72 Heading G4D  Each pulse from a fluid flow meter 10 opens a gate 52 to let through a number of pulses from a generator 51, the number being proportional to the price per unit of the dispensed fluid. The meter is a photo-electric or electromagnetic device whose output -pulses are sharpened by a monostable S. Its output pulses are counted in decimal stages C of a unit 11 which give BCD outputs, decoded at A to illuminate 7-segment displays 40 which register the total volume of fuel dispensed during an operation of a fuel dispenser 23. Each pulse opens the gate 52 to allow through pulses from the 100 Kc./s. generator 41. These high speed pulses are counted in further decimal stages C of a unit 12; the BCD outputs are each decoded at D to provide ten separate outputs. One pole of each switch 71 selects an appropriate output from D according to the price of the fuel; a second pole energizes respective portions of a 7-segment display 72 which registers the price. When the count accumulated in stages C equals that set up by the switches 71 a gate G releases a pulse to close the gate 52. The pulses release each time the gate 52 is opened are accumulated in stages C of a unit 13; the BCD outputs are again decoded at A to energize 7-segment displays 80 which register the total price of the fuel dispensed. A device R rounds the reading up or down to the nearest unit. At the start of the dispensing operation all the counters and registers are reset to zero but totalizers 41, 90 maintain running totals. A modification is described for use in a blending dispenser (Fig. 2, not shown).
