Variable marks are applied to the outside of bales of hay that assign each bale to a group based on pre-selected parameters collected during baling.

A water nozzle with a flow head is provided with at least two separate water supply devices that supply, in a controllable fashion, different water volume flows to the flow head. The flow head generates an annular jet from the different water volume flows. By controlling the water volume flows, alternatively a slim annular jet or a widened annular jet is generated by the flow head. A deflection element with a central outlet opening is provided, wherein the central outlet opening is arranged in a flow direction of the annular jet downstream of and spaced apart from the flow head. A deflection device surrounds the central outlet opening. A diameter of the central outlet opening is designed such that the slim annular jet is able to pass through the central outlet opening while the widened annular jet impacts on the deflection device surrounding the central outlet opening.

A double tentacle pump system for a liquid sprayer includes first and second tentacle pumps positioned serially within a flow path that extends between a liquid container and the outlet of the sprayer. A motor is configured to actuate the first and second tentacle motors in response to a user directed trigger, thereby causing fluid to be moved from the container and expelled from the sprayer.

A haze generating device for generating aerosol from a liquid includes at least one chamber in which the aerosol is generated. Each chamber includes a housing including a bottom and a side wall extending from the bottom to a top of the chamber, an ultrasonic transducer at the bottom, and a filter element at the top. The chamber is at least partially filled with a liquid to a filling level such that at least an ultrasound emitting surface of the ultrasonic transducer is immersed in the liquid. The chamber has a directed gas inlet at the side wall that directs a gas stream introduced into the chamber in a direction substantially parallel to a surface of the liquid and substantially along the side wall. The filter element includes guide surfaces that direct the gas stream out of the chamber in a direction substantially perpendicular to the surface of the liquid.

A sprayer system having a trailer, which is pulled by a tractor or other tow body, and has a tank carrying liquid to be sprayed and a spray head. The trailer has a peristaltic pump mounted on a frame and driving pumping power from the wheels of the trailer so that the sprayer is self pumping when the trailer is pulled. The peristaltic pump provides a smooth flow by providing a multiplicity of pulses of liquid produced by the pump from the rotation of the trailer wheels by wrapping the compressible tube of each pump around an assembly of rollers which are rotated by drive wheels. The tube is wrapped at least 360 around the rollers and is held stationary by being connected to fixed outlet and inlets of each pump. The tube lies side by side on at least one of the rollers of each assembly and overlaps that roller.

A tank holding a quantity of liquid releasably connects to a portable pump assembly through a connector to provide a portable sprayer. The tank connects to a feed line that supplies spray nozzle with the liquid. The connector combines a quick disconnect connector with a pressure relief valve. The portable pump assembly includes an electric pump, a switch assembly, and a check valve. The portable pump assembly directs gas through the check valve into the connector to increase the gas pressure in the tank and force the liquid in the tank to flow through the feed line and out the spray nozzle. The switch assembly turns off the electric pump when the gas pressure in the tank exceeds a predetermined limit while maintaining the flow of liquid through the spray nozzle.

An application apparatus includes a nozzle device (20) injecting a damping material from a nozzle hole (20a) to a vehicle body, an articulated robot (21) moving the nozzle device (20) relative to the vehicle body, a supply section including a supply pump (22), and a supply passage (27), and continuously driving the supply pump (22) to continuously supply the damping material from the supply pump (22) to the supply passage (27) in a substantially uniform amount, a return passage (33) branched from the supply passage (27) and returning the damping material to the supply pump (22), and a gun (32) and a return valve (34) switching a supply destination of the damping material between the nozzle hole (20a) and the return passage (33) based on information on applying the damping material to the vehicle body.

The purpose is to provide a fluid feeding system which can feed fluid so that an internal pressure fluctuation of an introduction chamber provided to a discharging device is minimized to minimize a poor discharge of the fluid, and to provide a molding system provided with the fluid feeding system. The fluid feeding system 50 includes a feed channel 60 connected to the discharging device 20, a pump 80 connected to the feed channel 60, a valve 70 for blocking a flow of the fluid that flows toward the introduction chamber 28 via the feed channel 60, and a control device 100 for determining a pressure state on the pump 80 side and carrying out an opening-and-closing control of the valve 70 based on the determination result. The control device 100 carries out the opening-and-closing control in which the valve 70 is made into an open state when the control device 100 determines that a pressure P1 on the pump 80 side reaches a pressure state exceeding a given pressure.

A method of controlling a flow rate includes selecting an operating condition defined by an operating flow rate and an operating pressure, comparing the operating flow rate to a threshold flow rate, and executing an adaptive calibration routing if the operating flow rate is greater than or equal to the threshold flow rate. The adaptive calibration routine includes measuring the operating pressure, measuring a first flow rate through a first meter, and modifying a pressure-flow table based on the operating pressure and the first flow rate.
