  • Patent number: 10278328
    Abstract: A grain cart is provided having a storage hopper for holding crop material, load cells positioned on the grain cart to measure a weight of crop material in the grain cart and an indicator connected to the load cells. The indicator can be operative to receive signals from the load cells indicating the weight measured by the load cells and to send an electrical signal on an output connection in response to a predetermined weight of crop material being removed from the grain cart. The output connection can be electrically connected to a close gate conductor wire that is operatively connected to the gate actuator, so an electrical signal generated by the indicator on the output connection of the indicator causes the gate actuator to close gates in the storage hopper stopping crop material from being discharged from the storage hopper.

  • Patent number: 8985161
    Abstract: Method of controlling a container filling machine comprising a plurality of filling elements. Each of the filling elements has a flow measuring device which is used to measure the volume of filling material dispensed from its filling element. During filling, the time that a first filling element is open to dispense a predetermined volume of filling material is measured. A second filling element is then opened for essentially the measured time to thereby dispense essentially the predetermined volume of filling material into a second container. As an alternative, a time may be calculated from the measured times of a plurality of filling elements, which calculated time may be used to determine for how long another filling element is opened.

    Abstract: A non-pressurized fluid level shutoff system for a fuel tank includes a fuel receiver having a flow control valve that opens in a direction opposite a direction of fuel flow, and that cannot be manually overridden. A fuel sensor funnels fuel through a fuel jet outlet orifice to form a stream of fuel across a cutout section, and a supplemental peripheral port connected between an outlet orifice mixing chamber and the interior of the tank is oriented perpendicular to the stream of fuel across the cutout section, to interfere with the stream of fuel when the sensor is submerged in fuel in the tank, to further reduce any residual fluid flow signal when the sensor is fully submerged, allowing the flow control valve in the receiver to close completely.

  • Patent number: 6148877
    Abstract: A fluid filling system is disclosed wherein containers to be filled with fluid materials are supplied first to one or more time-metered filling stations, and then to a weight-metered filling station. At first, the time-metered filling station(s) is/are inactive, and only the weight-metered filling station is used to fill a first container to a desired final weight. A timer is used to monitor the filling time necessary to reach the desired final weight. When later containers are then supplied to the time-metered filling station(s), they are filled at each time-metered station for a filling time which is dependent on the previously measured filling time for the weight-metered filling station. These containers are then "topped off" by the weight-metered filling station to precisely fill them to the desired final weight, and the time required for such topping off is measured for use in subsequent modification of the filling times at the time-metered filling stations.

  • Patent number: 5787943
    Abstract: A procedure and a device for dosing free-flowing media irrespective of its viscosity into containers. It is based on the task of providing an inventive solution for filling machines of the procedure, allowing the dosing of free-flowing media into containers within an exact time regime. The task is solved by the filling media moving through the filling pump, flowing passed a flow sensor in a filling media flow, with the flow speed being measured and transmitted to a regulator in which the set value is stored which is then compared with the actual value measured in the flow sensor. To adapt the actual value to the set value, the output of the filling pump is changed until the actual and set values of the flow speed correspond. With the thus exactly determined flow speed, the filling flow of the filling media arrives at the starting sensor arranged at the outlet opening of the filling pipe and activates the sensor by flowing through a sensor section.

The first container is partially filled to a predetermined percentage of a target weight as measured by the scale. Flow into the container is then stopped by closing a valve controlled through the scale and microprocessor. The actual weight of the liquid introduced at this point is measured and a correction factor is determined by subtracting the predetermined percentage weight from the actual weight. Flow into the container is then resumed until a second predetermined weight is achieved as measured by the scale and equal to the target weight minus the correction factor. Flow at this point is stopped by again closing the valve.

    Abstract: The invention comprises a high rate pressure vessel filling process which improves the accuracy of filling pressure vessels to required gas mass. The approach overcomes heating effects of high rate filling and volume variation effects by slowly prefilling a series of temperature monitored and controlled cylinders of a set volume, then rapidly discharging the premeasured gas mass into the pressure vessel.

  • Patent number: 5570731
    Abstract: Apparatus for supplying a plurality of containers with liquid. The apparatus performs the steps of introducing into a first container a first percentage of a predetermined final amount and subsequently introducing in steps additional liquid until said predetermined amount is reached, introducing into a second container a percentage of said predetermined amount greater than the initial percentage introduced into said first container and then introducing additional liquid into said second container in steps until said predetermined amount is reached, and continously introducing into a third container an amount of liquid within a tolerance of said predetermined amount, and wherein the amounts of liquid introduced into the container are measured and determined by weight. A microprocessor connected in circuit with a scale is used to control a valve through which the liquid is introduced into the container.

  • Patent number: 5022444
    Abstract: Apparatus for filling containers alternately with predetermined quantities of material has two container positions to be fed alternately and a material guide arrangement with alternative outlets that supply the material to containers at these two positions. A pair of container support frames are arranged side by side on the front pair of a main frame, and these support frames are mounted by pivot arms to the main frame in a parallelogram arrangement. Rearwardly of the main frame front part are counterweights or counterbalances supported on either upper or lower ones of the pivot arms. An upper part of each of the support frames has a mechanism that coacts with a cooperating mechanism on the material guide arrangement to change the position of a diverter plate when the container that is being filled overbalances the corresponding counterbalance and causes the associated support frame to descend.

  • Patent number: 4092721
    Abstract: Apparatus for controlling and adjusting the weight of doses of a loose product in a rotating metering head having telescoping volumetric members distributed therearound. The apparatus includes a rotating control head having a set of sample telescoping volumetric members. A main duct feeds the product to the metering head. A secondary duct is branched off the main duct to feed the control head. A scale is operative to receive individual sample doses as provided by the telescoping members of the control head and to discharge them, after the weighing thereof has been completed, to the metering head. A control assembly adjusts in a concurrent proportional mode the volume of the telescoping members of the metering and control heads according to the weight variations of the weighed product versus the scale reference value.
