The present invention relates to a system for delivering an agricultural formulation, having a container (1) for holding the agricultural formulation, the container (1) having a removal opening (19), a delivery unit (2), securely fastened in or to the container (1), for delivering the agricultural formulation located in the container (1) through the removal opening (19). The system also comprises a drive unit which, in order to drive the delivery unit (2), separately from the delivery unit (2), is coupled detachably to the delivery unit (2), wherein the drive unit has a hydraulic unit (12), which comprises a cylinder chamber (9), a piston (20) that is movable back and forth in the cylinder chamber (9), and an outlet opening (22) for a hydraulic fluid, and has a hydraulic line (8) which is coupled to the outlet opening (22) and able to be coupled to the delivery unit (2). In the system according to the invention, the hydraulic fluid is water or rapidly biodegradable. Furthermore, the hydraulic unit has a further cylinder chamber for driving the piston by means of a further hydraulic fluid. The invention also relates to a method for delivering an agricultural formulation.

A mixing module includes two inlets, an integrator, and a valve member. The integrator has two chambers each having a near end and a far end, and the valve member is movable between two positions. One of the inlets is connected to the near end of one of the chambers and the other inlet is connected to the near end of the other chamber when the valve is in one position. When the valve is in the other position, one of the inlets is disconnected from the chambers and the near ends of the chambers are connected.

Applicant discloses a two part polymer mix for use in the aircraft industry that is applied with pneumatic mix and spray gun. The two part cartridge is used in the mix and spray gun so the mix is applied immediately upon mixing, but the two components are kept separated unless the gun is applying the mix. The mix cures to form a clear sealant that allows for inspection of cracks and corrosion beneath the sealant. It cures quickly so that the coated part may be further processed, for example in the assembly line during aircraft build. Applicant further discloses multiple spray gun systems for applying such a two-part polymer mix to aircraft parts.

The present application thus provides a wash system for use with a compressor having a bellmouth and one or more extraction pipes. The wash system may include a water source, a first fluid source, a mixing chamber in communication with the water source and the first fluid source, a bellmouth line in communication with the mixing chamber and the bellmouth, and a stage line in communication with one of the extraction pipes.
