An electrostatic oiling system for use with single blanks in batch systems having an open spray chamber without the need for a negative vacuum chamber. Further, the provided electrostatic oiling system may utilize induction beams and a charge wall that allows for utilization of a smaller vacuum system. Further, the provided electrostatic oiling system may provide variable blank coverage without the need for metered pumps.

An electrostatic fluid delivery system is configured to deliver fluid, such as a disinfectant fluid, onto a surface by electrically charging the fluid and forming the fluid into a mist, fog, plume, or spray that can be directed onto a surface, such as a surface to be cleaned. The system atomizes the fluid using a high-pressure air stream and passes the fluid through an electrode inside a nozzle assembly to charge, such as negatively charge, droplets of the atomized fluid. The system uses a unique nozzle design that is configured to optimally atomize the fluid into various sized droplets.

An electrospray printing system that produces conformal films includes a printhead. A housing of the printhead includes a solution reservoir operable to receive a solution that includes a print material suspended in a solvent. An electrical potential is applied to the solution to produce an electrically charged solution that is emitted from the solution reservoir towards a target substrate. Electrostatic focusing is used to guide the print material to the target substrate.

A coating apparatus includes a first module and a second module constituting a coating area where a coating target is coated. The first module includes a first frame and a coating robot. The second module includes a second frame. When the first module and the second module are arranged to adjoin each other in a movement path direction in which the coating target relatively moves along the coating area, the first frame of the first module and the second frame of the second module that are arranged to adjoin each other are configured to be coupled together.

A selectively configurable spray gun may include a gun body comprising a selectable forward section and a rearward section. The rearward section may be connected with either of two or more selectable forward sections so as to selectively configure the spray gun to operate either with a dense phase powder supply configuration or a with dilute phase powder supply configuration. The rearward section may include a selectable powder flow path that is connectable at an inlet end to a source of dense phase powder and at an outlet end to a selectable spray nozzle in the selectable forward section that may optionally include a diffuser. An adapter may be used to connect the rearward section with a selectable spray nozzle or air cap. A manual spray gun embodiment is also presented. A selectively configurable spray gun for use with a dense phase powder supply may include a smaller diameter powder tube that extends through a larger diameter powder tube.

The invention relates mainly to an above-ground farming module which includes an element for supporting plants defining a root chamber for the aerial portion of the plants, and which includes means for forming a mist of nutritional solution (9) and means (25, 26) for circulating said mist of nutritional solution (30) located in the root chamber (4). The means for forming the mist of nutritional solution (9) advantageously include an ultrasound mister (10) located in the bottom of a misting cell (9) on which at least one opening for propagating the nutritional mist (20) in the root chamber (4) is arranged, and the means (25, 26) for circulating the mist of nutritional solution (30) are located next to said opening (20).

This disclosure provides an apparatus, system, and method for thermal spraying a metal cladding on a substrate. The apparatus may include a housing having a first electrode and a second electrode disposed in the housing. The second electrode can be spaced apart from the first electrode.
