  • Patent number: 11325824
    Abstract: A fuel nozzle receptacle for use with auxiliary fuel tanks is disclosed. A fuel nozzle is received in a receptacle or boot in a nozzle-down orientation that defines a secure storage for the nozzle. The receptacle includes a drain port on the lower end of the receptacle and a drain tube is attached to the drain port. A valve is plumbed into the receptacle. When residual fuel has accumulated in the receptacle, the end of the drain tube is fed into an appropriate holding vessel and the valve is opened to allow the residual fuel to drain from the receptacle into the holding vessel.

  • Patent number: 5450881
    Abstract: A method and apparatus for drawing and measuring an amount of liquid agrichemical and dispensing the measured amount of agrichemical for mixture with water and eventual application onto a field. The agrichemical is drawn into a measuring vessel by suction pressure, created in one embodiment by an air compressor and valving system, and in another embodiment by a valve-pump in conjunction with a 3-way valve. The agrichemical is then dispensed from the measuring vessel either by positive pressure created by the same air compressor/valving system, or by suction pressure created by valve-pump/3-way valve. The valve-pump provides both a mixing chamber for the agrichemical and water prior to tank storage for eventual application, and controllable suction pressure for drawing the agrichemical out of the measuring vessel for mixing. The valve-pump is also self-cleaning thereby reducing the possibility of cross-contamination.
