  • Publication number: 20130199262
    Abstract: Fluid level measurements for the shared tank and outflow information provided by calibrated flow meters corresponding to dispensing stations connected to the shared tank may be used to derive a filled volume model for the tank as a function of fluid level. Subsequently, a filled volume change for a shared tank over a selected time interval may be determined from pre-change and post-change fluid level measurements. The change in filled volume may be compared with the total fluid flow over the selected time interval as indicated by the flow meters of active dispensing stations. If the filled volume change for the tank is substantially different than the total fluid flow indicated by the flow meters, the flow meters may be collectively adjusted to provide a more accurate indication of the filled volume change in the shared tank.

  • Patent number: 4570823
    Abstract: The soap solution dispenser contains a reservoir into which opens an outlet or outflow opening of a container. In the reservoir there is present a float body or float which is pivotably mounted and provided with at least one indicator flag. Conjointly with the drop of the liquid level in the soap solution reservoir the float body also descends, which causes a displacement of the indicator flag. During the lowering of the surface of the soap solution the indicator flag moves along a viewing window formed in a cover or covering hood. There is thus signalled or indicated that the content of the soap solution in the reservoir is quite small or nearly consumed, so that the container now should be exchanged. One resulting advantage of the invention is that the indicator flag moves externally of the soap solution, so that the indicator flag cannot become stuck or bind, and thus, always remains readily visible.

    Abstract: An apparatus for supplying fluid of preset quantity comprises a fluid supplying pump provided in a fluid supplying pipe arrangement, a motor for driving the fluid supplying pump, meter for metering the fluid flowing in the fluid supplying pipe arrangement, and a control circuit for detecting that supplied quantity of fluid measured by the meter has reached a quantity smaller than a preset fluid supplying quantity by an estimated oversupply quantity of fluid, and stopping the motor from being driven. The estimated oversupply quantity of fluid is set to a quantity equal to a quantity of fluid supplied by the fluid supplying pump after the motor is stopped from being driven and rotates due to inertia.

  • Patent number: 4360128
    Abstract: A beverage dispenser in which a sensor provides an output corresponding to the level of the beverage in a storage reservoir from which the beverage is dispensed. In response to user actuation a dispensing valve is enabled for such a time interval, determined in accordance with the output of the sensor, as to compensate for variations in flow rate due to variations in the beverage level in the reservoir. The level sensor output is also used to control a level-indicating display and to disable the reservoir heater when the reservoir is empty. Preferably the sensor is a strain gauge adhered to the surface of a relatively thin resilient beam which supports a portion of the reservoir.

  • Patent number: 4216529
    Abstract: A system for monitoring and controlling the operation of a plurality of fluid dispensers, such as gasoline pumps or the like in a self-service gasoline station is disclosed. The system includes an operating console that may be located in a station building and has electronic displays, dispenser selecting push buttons and a keyboard including numeric and functional switches, all of which an operator can use to control the operation of the system. A mode select switch permits operation of the system in various modes, selected ones of which permit an operator to obtain various period totals of both volume and cost, to control normal postpay or prepay dispensing transactions, check inventory as well as set or reset the cost per volumetric unit, among other operations. The system can include electronic displays at the gasoline pump and permit price setting of the fluid product from the console.

  • Patent number: 4101056
    Abstract: Method and apparatus suitable for the retail sale of gasoline (as well as for other fluid delivery systems) in terms of standard quantities (e.g., gallons) at a standard temperature, such as 60.degree. F. The apparatus for retail gasoline sale provides a pressure differential for moving the gasoline from a storage tank to a hose, and it includes a metering device preferably having a rotating shaft and a shaft-angle encoder for generating a positive angle continuous, electrical signal as a function of the shaft angle output. The instantaneous temperature of the gasoline in the nozzle is sensed and a thermal value signal generated from it several times per second. A rapid electronic computer computes from the continuous gallonage signal and the thermal value signal, at intervals of several times per second, the gallonage corrected to standard gallons at 60.degree. F. and actuates a display of the computed dispensed gallons in terms of standard gallons at 60.degree. F.

  • Patent number: 4083473
    Abstract: A liquid blending system for providing three grades: (a) a first base grade; (b) a second base grade; and (c) a fixed blend proportion of the two. A blend control lever coupled to a valve is selectively driven by a differential receiving inputs from fluid meters in the base grade lines. Opposed solenoids pull the lever to one extreme or the other for the two base grades.

  • Patent number: 4067486
    Abstract: A liquid fuel dispensing system having a plurality of dispensing pumps each generating electric pulses according to the volume of fuel dispensed and a central control where payment is made. A data transmission link couples each pump to the central control and each pump has a pulse store which accumulates pulses generated by the pump during a dispensing operation. A sampling mechanism at the central control samples the outputs from the pulse stores which are updated at each sampling. First and second storage elements are provided to store information at the central control relating to previous pump transaction whereby such pump can be cleared for use by second customer before first customer has paid.

  • Patent number: 4044269
    Abstract: The circuit arrangement includes a transformer having a primary side included in at least one phase conductor of a polyphase supply for the load. A control circuit is connected to the secondary side of the transformer and includes a threshold circuit receiving a control signal from the transformer, a memory circuit receiving a threshold signal from the threshold circuit, a bistable switch connected to the threshold circuit and the memory circuit and switched, by the threshold signal, to a position preventing the stored signal from being passed on from said memory circuit, and a controlled electronic switch inserted in the phase conductor and controlled and opened by the stored signal. A resetting switch is operable to reset the control circuit to the initial state, and a delay device may be interposed between the memory circuit and the controlled electronic switch to delay opening of the latter until after a subsequent operation of the repetition-blocking device.

  • Patent number: 4027783
    Abstract: Tally means for a liquid dispenser which selectively draws measured quantities of liquor for discharge through a discharge sprout. A liquid pressure responsive sensor is connected to the discharge line and is responsive only to passage of liquid. The sensor has a chamber with a diaphragm closing one end. A chamber inlet, larger than the outlet, leads through the end closed by the diaphragm. Because of differential in orifice size, liquid accumulates in the chamber causing the diaphragm to deflect but not respond to air flow. A piston in the chamber is moved by the diaphragm to actuate a tally apparatus to provide both printed record and a display of the number of drinks dispensed.

  • Patent number: 4007855
    Abstract: A liquid metering dispenser is actuated by a trigger. The trigger releases a valve rod which is spring actuated to close a fluid pressure inlet, opening the discharge outlet of the dispenser to release a stored measured charge of liquid by operation of a spring actuated piston. The trigger is cocked by drawing the valve rod to close the discharge valve and open the liquid pressure inlet; the liquid under pressure enters the storage chamber, compressing the piston spring until it strikes an adjustable stop. The piston and spring assembly is readily removable for cleaning and servicing.
