Abstract
Abstract The specification discloses a remote control system, especially for self-service fuel, chemical, or other liquid dispensing pumps in which each dispensing pump is provided with a call switch which actuates a signal in a remote location whereupon the operator in a remote location can enable the respective dispensing pump to dispense fuel. The remote location is operable for monitoring the quantity of fuel dispensed and can include counter means for totalizing or limiting the quantity dispensed from each of a plurality of remote controlled dispensing pumps. The signal which is actuated in the remote station consists of visual signal, such as a lamp, and an audible signal, such as a bell or buzzer, with the audible signal sounding only so long as the customer has the button of the call switch depressed at the respective dispensing pump, while the visual signal remains illuminated after the button on the dispensing pump is released. When the operator in the remote location takes the action necessary to enable the dispensing pump, the visual signal in the remote station is extinguished.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
194 words
In a control systeM for a customer operated dispensing installation having dispensing pump means and a remote control station; each dispensing pump being normally disabled and having electrically energizable enabling means, a primary source of energy, a call switch at each dispensing pump actuable by a customer when dispensing from the respective pump is desired, signal means in said remote station in circuit with said call switch and said primary source of energy, and operable in response to actuation of said call switch, said signal means comprising an audible signal and a visual signal, an auxiliary source of energy under the control of said visual signal operable to maintain said visual signal energized following release of said call switch, a control switch in said remote station having a first set of contacts in circuit with said primary source of energy and a second set of contacts in circuit with said auxiliary source of energy, said control switch being actuatable by an operator in said remote station and operable when actuated to connect said enabling means to said primary source of energy while simultaneously interrupting said auxiliary source of energy to extinguish said visual signal.
Claim 2
Dependent Claim
194 words
In a control systeM for a customer operated dispensing installation having dispensing pump means and a remote control station; each dispensing pump being normally disabled and having electrically energizable enabling means, a primary source of energy, a call switch at each dispensing pump actuable by a customer when dispensing from the respective pump is desired, signal means in said remote station in circuit with said call switch and said primary source of energy, and operable in response to actuation of said call switch, said signal means comprising an audible signal and a visual signal, an auxiliary source of energy under the control of said visual signal operable to maintain said visual signal energized following release of said call switch, a control switch in said remote station having a first set of contacts in circuit with said primary source of energy and a second set of contacts in circuit with said auxiliary source of energy, said control switch being actuatable by an operator in said remote station and operable when actuated to connect said enabling means to said primary source of energy while simultaneously interrupting said auxiliary source of energy to extinguish said visual signal.
Claim 3
Dependent Claim
67 words
A control arrangement according to claim 1 in which said dispensing pump means includes at least two individual dispensing pumps each having a respective call switch and a respective enabling means, said remote station comprising a said visual signal for each dispensing pump and a said control switch for each pump, said audible signal comprising a single audible signal device common to all of said dispensing pumps.
Claim 4
Dependent Claim
37 words
A control arrangement according to claim 2 which includes a diode interposed between said signal device and each said call switch, and a further diode interposed between each call signal lamp and the call switch pertaining thereto.
Claim 5
Dependent Claim
32 words
A control arrangement according to claim 2 which includes a lamp on each said dispensing pump connected to become energized when the enabling means pertaining to the respective dispensing pump is energized.
Claim 6
Dependent Claim
154 words
A control arrangement according to claim 2 which includes a first relay in said remote station energizable in response to actuation of each said control switch, energization of said first relay connecting said primary source of power to the respective said enabling means and interrupting the connection of said auxiliary source of power with the respective said signal lamp and also establishing a holding circuit for the said first relay, switch means on the respective dispensing pump actuated preparatory to a dispensing operation, a second relay in said remote station energizable in response to actuation of said switch, energization of said second relay interrupting the holding circuit to said first relay and establishing a connection from said primary source of power to said enabling means, energization of said second relay also connecting a counting device on the respective dispensing pump to a counting device pertaining to the respective dispensing pump in said remote location.
Claim 7
Dependent Claim
34 words
A control arrangement according to claim 5 in which energization of said second relay also interrupts the connection of said auxiliary source of power with the visual signal pertaining to the respective dispensing pump.
Claim 8
Dependent Claim
106 words
A control arrangement according to claim 3 in which said visual signal is a signal lamp, said auxiliary source comprising a light sensitive resistor connected in circuit with said lamp via said resistor, and said resistor being disposed adjacent said lamp so as to be illuminated thereby whereby energization of the signal lamp by closing of said call switch will establish said auxiliary source of power to maintain said lamp energized while extinguishing of said signal lamp will interrupt said auxiliary source of power, each said source of auxiliary power being connected to the respective signal lamp between the lamp and the said diode pertaining thereto.
Claim 9
Dependent Claim
58 words
A control arrangement according to claim 7 in which each said signal lamp and the light sensitive resistor and the diodes pertaining to the respective call switch are mounted in a body to form an integral unit, said lamp projecting from one end of said body so as to be observable by the operator in said remote station.
Claim 10
Dependent Claim
19 words
A control arrangement according to claim 8 in which said body is in the form of an encapsulating resin.
Claim 11
Dependent Claim
31 words
A control arrangement according to claim 8 in which the electrical connection to the components in said body lead into the body from the end opposite the said one end thereof.
Claim 12
Dependent Claim
18 words
A control arrangement according to claim 10 in which said body comprises mounting lugs on the sides thereof.
