Fluid pump having pulsing means and money accumulator
Abstract
Abstract A CONTROL AND CHANGE MAKING DEVICE IS PROVIDED FOR A FLUID DISPENSING PUMP TO RECEIVE MONEY DEPOSITED BY A CUSTOMER AND STORE INFORMATION SIGNALS INDICATIVE OF THE AMOUNT OF MONEY RECEIVED. AS FLUID IS DISPENSED, PLUS ARE PRODUCED TO REDUCE THE AMOUNT OF STORED INFORMATION SIGNALS UNTIL THE DESIRED AMOUNT OF FLUID IS DESPENSED. WHEN THE AMOUNT OF FLUID DISPENSED REPRESENTS THE AMOUNT OF MONEY RECEIVED, THE DISPENSING IS AUTOMATICALLY STOPPED. IF THE AMOUNT OF FLUID DISPENSED IS LESS THAN THE AMOUNT OF MONEY DEPOSITED, THE CUSTOMER MAY OPERATE A CIRCUIT TO RECEIVE THE PROPER AMOUNT OF CHANGE. AS THE CHANGE IS GIVEN, THE STORED INFORMATION SIGNALS ARE REDUCED UNTIL NO INFORMATION SIGNALS REMAIN, AT WHICH TIME NO FURTHER CHANGE IS PROVIDED.
