A system and method of protecting plants while spraying having a hood mounted to a farm implement and positioned between plant rows and below plant vegetation. Extending through the hood into a hollow chamber is a hydraulic fitting having a spray nozzle. Heated water is supplied to the hydraulic fitting.

A modular apparatus for coating glass articles with a chemical compound includes a coating hood section (10a) including a series of interconnected walls (12) defining an interior chamber (18, 20a, 20b) having an inlet (32) and an outlet (44), a blower (24) positioned at least partially in the interior chamber (18, 20a, 20b) to carry air from the inlet (32) towards the outlet (44); and a connector (50) for connecting the coating hood section (10a) to an identical coating hood section (10b). The connector (50) for connecting being defined on at least one of the interconnected walls (12) of the coating hood section (10a).

A liquid dispensing device includes a body, a nozzle on an end of the body, a liquid container coupled to the body, and a piston configured to move in the body so as to control an ejection of liquid from the nozzle. The piston and the nozzle are configured to be detached from the body as an assembly.

A liquid dispensing device includes a body, a nozzle on an end of the body, and a liquid container coupled to the body and in fluid communication with the nozzle. The liquid dispensing device also includes a shielding member coupled to the body. The shielding member is configured to block a liquid ejected from the nozzle in order to form a clean edge of the liquid on a target surface to which the liquid is applied.

A liquid-emitting device for gravity-based irrigation systems includes a support structure that defines a first axis and has a nozzle for generating an irrigation jet coaxial with the first axis, a tubular body below the support structure, and a baffle plate facing the nozzle and rotatably mounted in the tubular body to rotate about a second axis. The nozzle is stationary and the second axis is free to rotate about the first axis with a precessional motion. Guides are removably coupled to the tubular body to interact with the baffle plate and prevent the precessional motion while allowing the rotational motion about the second axis. A diverting member may be removably positioned downstream from the nozzle to distribute the liquid over an area of the soil. An arrangement of a nutating liquid-emitting device in combination with an anti-nutating adaptation kit is also disclosed.

The invention relates to a dispenser 20 for the spray delivery of a preparation 18. The dispenser comprises: a reservoir 22 suitable for containing the preparation 18, a mechanical pump 24, a load chamber 26, a nozzle 28 having a delivery axis, and a delivery cone 30 having an axis. The mechanical pump is able, whenever operated: to take a predetermined amount of preparation from the reservoir, to supply said amount of preparation to the load chamber upstream of the nozzle, and to create a delivery pressure in the load chamber. The nozzle is able to deliver said amount of preparation in the form of an aerosol spray 180. The dispenser according to the invention is characterized in that the delivery cone comprises, in the proximity of the nozzle, at least one through-hole 320 suitable for putting the inside of the delivery cone into communication with the surrounding environment.

A cloud tower (11) receives microscopic particles (18) impelled by an inert gas (17) for deposition on a porous substrate (29) having vacuum (34) disposed on opposite side. To alter the size and/or shape of the deposition field without changing the entire tower structure, a pair of flaps (43, 44) are hinged (47, 48) on one side or on a pair of opposed sides of the cloud primary tower. Another embodiment places selectable tower inserts (36, 38) within the primary tower structure, fitting therein and sealing thereto.
