Abstract

A remote authorization apparatus for full-serve, self-serve vehicle fuel dispensing pumps. A transmitter carried by a station attendant may be activated to cause the emission of a radio signal. This signal is sensed by a receiver which actuates an associated control assembly to enable the reset mechanism in the fuel pumps for a preset time interval during which a customer may begin dispensing fuel. When the timed enabling signal ends, the pump or pumps which have begun service may continue, while all other pumps are returned to an inactive state. Other pumps may be enabled in the same manner by emission of the radio signal from the transmitter should other customers desire to use the self-serve vehicle fuel pumps, while previously authorized pumps are dispensing.

Claims

1. Apparatus for remotely authorizing the dispensing of fluids, comprising:

operator-actuatable transmitting means for producing an output signal;

receiver means in operative communication with said transmitting means for receiving said output signal;

a plurality of motor-driven pumps having electric resets for dispensing the fluids; and

circuit means comprising a timing circuit interconnecting said receiver means and said electric resets, said timing circuit producing a signal of fixed time duration for enabling said resets for said time duration after receipt by said receiver means of said output signal.

2. The apparatus according to claim 1 wherein said transmitting means produces said output signal as a radio signal.

3. The apparatus according to claim 2 wherein said receiver means comprises a radio frequency receiver.

4. The apparatus according to claim 3 wherein said circuit means further comprises a relay operatively connected to said timing circuit.

5. The apparatus according to claim 4 wherein said relay includes contacts in series connection with said electric resets.

6. The apparatus according to claim 5 wherein said circuit means further includes a lamp connected to said timing circuit and being illuminated during occurrence of said signal of fixed time duration.

7. The apparatus according to claim 4 wherein said relay includes two sets of normally open contacts, said contacts being interconnected with said electric resets.

8. A remote authorization device, comprising:

a radio signal transmitter;

a receiver in signal-receiving communication with said transmitter;

a plurality of reset motors; and

timing circuit means including a timer interconnecting said reset motors and said receiver, said timer actuated by said receiver and presenting an output signal for a fixed time interval, for enabling said reset motors for actuation during a fixed time interval.

9. The device according to claim 8 wherein said timing circuit means includes a lamp connected to said timer and illuminated during fixed time interval for which said reset motors are enabled.

10. The device according to claim 9 wherein said timing circuit means includes a relay having contacts interconnected with said reset motors.

11. The device according to claim 10 wherein said relay includes two sets of normally open contacts interconnected with said reset motors.
