Abstract: The method and apparatus of the present invention enables a farmer or other agricultural worker to conveniently and efficiently calibrate the rate at which a granular material, particularly a granular pesticide, is dispensed from an agricultural planter. A stationary calibration unit has a motor and a rotatable shaft. The rotatable shaft is insertable into a pesticide dispenser forming part of the agricultural planter. Rotation of the shaft simulates movement of the agricultural vehicle carrying the planter in the field to determine the rate at which a granular pesticide is dispensed. The dispensing rate may thereafter be adjusted to a desired value and checked by again running the motor of the stationary unit to simulate field conditions. The calibration unit enables adjustment and recalibration of the dispensing rate of granular pesticide from an agricultural planter without the necessity and burden of performing trial and error field measurements and adjustments.

Abstract: A dual chamber Brix measuring cup which can be used to determine whether a fountain syrup dispenser is dispensing the proper ratio of water to syrup, referred to a a Brix measurement. The cup is basically two abutting cylindrical chambers, one to receive water dispensed from the nozzle and the other adapted to receive the syrup by means of a diverter tube. The cross sectional areas of the water and syrup chambers are in the ratio of the ideal water to syrup ratio in the dispensed product. In a first embodiment, a series of calibrated marks are provided on each of the two chambers, such that the mismatch of column heights can be translated into a reading of acceptability, for example if the syrup and water heights are within two lines of each other, that enable a tolerance band of acceptable mismatches to be easily seen visually. In a second embodiment, a slider element is provided which is vertically slideable on the syrup chamber. A calibration mark thereon is aligned with the syrup height, and when the water height falls within a tolerance range marked on the slider element, an acceptable ratio is indicated.

Abstract: A fluid dispenser pumps fluid in increments. The dispenser includes a computer which, on command, determines the volume of fluid dispensed per increment, the determined value constituting a calibration value which is stored in the memory of the computer. A controller which may include the computer as a component provides for dispensing a selected number of doses, each of a selected volume. The controller can also specify a time interval between the delivery of successive doses. The dispenser is particularly useful in combination with apparatus for charging petri dishes with agar.

Abstract: An apparatus and method for operating and calibrating a paint mixture delivery system includes a positive displacement fluid cylinder and a linear transducer that monitors operation of the positive displacement fluid cylinder. A controller is connected to a servo drive whose operation manipulates the performance of the positive displacement fluid cylinder. Operation of the fluid delivery system is controlled such that the ratio of paint or resin to catalyst or hardener can be accurately controlled and calibration of the discrete fluid flow sensors can be quickly and conveniently calibrated to assure delivery of the respective fluids are the desired mixture ratio.

Abstract: A chemical delivery system connects to a chemical tank and includes a union connected to the tank outlet and providing an antirotation feature, in addition to threads, to prevent rotation of the assembly in response to asymmetric loads. A measuring tube alternately receives liquid from the tank and is isolated from the tank. While isolated from the tank, liquid is withdrawn from the tube by a pump under conditions allowing the pump to be calibrated. The assembly is cantilevered from the tank outlet and is of reduced length and weight producing a device which is not prone to overstress the tank outlet.

Abstract: In one aspect, a calibration method for a multi-variety seed meter may include terminating a supply of seeds to a seed meter and subsequently operating the seed meter to discharge seeds therefrom. Additionally, upon terminating the supply of seeds to the seed meter, the method may include monitoring a parameter indicative of an amount of seeds remaining within the seed pool based on data received from a first sensor. The method may also include monitoring an operation of the seed meter based on data received from a second sensor to identify the occurrence of a starvation event for the seed meter and determining a target value for the monitored parameter based at least in part on a starvation interval defined between the termination of the supply of seeds to the seed meter and the occurrence of the starvation event.

Abstract: A system and method are provided for quantifying a degree of discontinuity of material flow from a meter roller. A flowable particulate material is fed into a meter roller rotated at a constant speed while a camera takes pictures or images of the product dispensed from the roller. The images of the product taken by the camera are analyzed to determine the area of the image represented by the product. The areas of product within the images are then compared with one another to determine how continuous the area of product is in the respective frames. The area measurement for each image is calculated at a frame rate for the camera that, when compared to the flute frequency range of the roller, provides a frame per flute ratio that ensures all particles of product dispensed from the roller are captured in an image without overlap of product between frames.
