  • Patent number: 10006453
    Abstract: A peristaltic pump comprises a flexible tube, a compression mechanism being actuatable for compressing the flexible tube, an upstream valve mechanism being actuatable to selectively open or close the tube upstream of the compression mechanism and a downstream valve mechanism being actuatable to selectively open or close the tube downstream of the compression mechanism. A drive mechanism actuates the compression mechanism, the upstream and downstream valve mechanisms. A pressure sensor measures a pressure signal indicative of a pressure in the tube between the upstream and downstream valve mechanisms. First and second signal values indicative of a pressure value downstream the downstream valve mechanism and upstream the upstream valve mechanism, respectively, are computed from the measured pressure signal. A threshold value is computed from the first and second signal values, and the measured pressure signal or a derived signal parameter is compared with the threshold value to detect a fault condition.

    Abstract: A dual piston/poppet valve in a fuel dispenser works with a two-stage valve to help eliminate errors from an inferential flow meter. When the two-stage valve opens partially, a secondary fuel path is opened in the dual piston/poppet valve. A sensor detects the opening of the secondary fuel path and reports its opening to a control system. The two-stage valve opens fully and a primary fuel path is opened concurrently. During transaction completion, the two-stage valve partially closes, resulting in the closing of the primary fuel path. When the two-stage valve closes completely, the secondary fuel path closes. The sensor detects the closing of the secondary fuel path and reports the closing to the control system. Based on the outputs of the sensor, the control system accepts or declines input from a flow meter.

The motion sensor includes components to detect motion, such as that caused by a vehicle striking the dispenser housing, and provides a signal to a controller which cuts off electrical power through an electrical supply line to electrical components of the dispenser. With power disconnected from electrical components of the dispenser, potential arcing of electricity to those electrical components when they become damaged, or potential arcing when the electrical supply line becomes damaged can be prevented to potentially prevent a resulting fire or explosion.

  • Patent number: 5816448
    Abstract: An arrangement for dosing fluids, such as beverages, comprising a flow meter arranged in the fluid dosing duct, an on-off valve arranged in the dosing duct downstream of the flow meter for releasing or cutting the flow of fluid, and an evaluation circuit that transmits a switching off control signal (closing signal) to the on-off valve when a predetermined amount of fluid has passed through the flow meter. The flow meter and on-off valve are preferably an impeller flow meter and an electrically actuable on-off valve, respectively. In order to improve the dosing accuracy, a sensor is provided with the flow meter for sensing the speed of flow given, for example, by the frequency of rotation of the impeller and for supplying, to the evaluation circuit, a preferably electric sensor signal that corresponds to the speed of flow.

  • Patent number: 5711456
    Abstract: An above ground fuel transfer module includes a bottom surrounded by vertical side walls forming a fuel containment vessel. One corner of the support frame has the vertical side walls recessed to form a recessed compartment for a fuel dispensing pump and electrical equipment which are thereby protected by the frame and side walls from being damaged by vehicles or the like operated in the vicinity. An electronic circuit card connected to a control panel controls the transfer of fuel and monitors safety conditions.

  • Patent number: 5632411
    Abstract: A meter for measuring the quantity of milk by weight flowing in a pipeline comprises a main housing having a main milk inlet pipe and a main milk outlet pipe. A buffer chamber in the main housing receives and holds the milk prior to weighing. A weighing container in a weighing chamber sequentially receives discrete quantities of milk from the buffer chamber through a communicating opening. The weighing container is mounted on a load cell, which sequentially weighs the settled weights of the discrete quantities of milk, the settled weights of which are cumulatively stored. Weighed milk is discharged from the weighing container through a discharge outlet opening. A main valve member and a secondary valve member selectively close the communicating opening and the discharge outlet, respectfully. Milk samples are collected in a milk sample reservoir on discharge of weighed discrete quantities of milk from the weighing container for subsequent collection in a collection jar.

  • Patent number: 5441176
    Abstract: A volumetric measuring and dispensing apparatus for the dry measure of particulate matter such as sand, or gravel, which apparatus includes one of either (I.) a rotary table spaced slightly from a body having a stationary interrupted circular wall which defines a storage zone; or (II.) a stationary table spaced slightly from a rotating body having an interrupted circular wall which defines a storage zone. The storage zone includes a distally located gate, under which a predetermined amount of particulates can pass as one of the table or said body rotates relative to the other. The apparatus also includes a retention zone on the table outside of the gate for residual material. The particulates fall into a collection vessel such as a hopper or conveying belt. The contents of the storage zone may be replenished from a conventional feed hopper or manually.

  • Patent number: 5363988
    Abstract: This invention relates to an improved fuel dispenser comprising a gas detector responsive to the presence of gas within the fuel. The gas detector provides an electrical signal indicative of the presence or absence of gas to a computer which controls a valve, and thus the dispensing of fuel in dependence upon the signal received from the gas detector.

  • Patent number: 5360139
    Abstract: An automated fueling facility allows untrained persons to safely dispense homogenous phase liquid methane from a cryogenic storage tank into a motor vehicle. The fueling facility automatically maintains pressure on the liquid methane within a predetermined safe operating range using methane gas trapped in the cryogenic storage tank. The pressure on the liquid methane is at least set equal to a set pressure equal to the sum of the saturation pressure of the liquid methane plus an additional amount to help to ensure that it remains in a fully saturated condition after absorbing any heat during pumping from the storage tank. A pump is cooled by placing it in the storage tank and circulating liquid methane through the pump and back into the storage tank. A dispenser, including nozzle for connecting to a motor vehicle, is cooled by circulating liquid through the nozzle and back to the storage tank through a receptacle on the dispenser to which the nozzle is connected.

  • Patent number: 5323721
    Abstract: A planter monitor system monitors, measures and displays a plurality of planter performance parameters. The system includes a display console, a plurality of row unit modules and a plurality of seed sensors. The system can be used with a wide variety of planters made by different manufacturers and on many different planter types. The system can accurately monitor a wide variety of seed types (e.g. both small and large) and a wide variety of seed planting rates (low and high) and any combination thereof which can occur within the wide scope of seed planting. The system calculates an error rate from a set of data, in graph form, representing experimentally determined actual seed rates versus seed rates as would be measured, thus allowing the operator to optimize seed population and distribution by adjusting the speed of the planter apparatus and/or the seed distribution system.
