The disclosure relates to a painting system component, in particular a rotating bell (1) for a rotating atomizer, including a main body (1) and a surface coat (8) at least on a part of the surface of the main body (1). The surface coat (8) reduces the tendency of the painting system component to become dirty and/or improves the ease of cleaning of the painting system component.

A method for producing a connecting rod for an internal combustion engine, having a small connecting rod eye for holding a piston pin and having a large connecting rod eye for holding a crank pin, wherein at least one connecting rod eye has at least one geometric deviation from a cylindrical inner contour. It is provided according to the invention that the at least one connecting rod eye is formed by creating a bore with a cylindrical inner contour, and coating the bore with a coating comprising a resin with solid lubricant particles embedded therein. The coating forms the at least one geometric deviation from the cylindrical inner contour of the at least one connecting rod eye.

Provided is a rotary atomization painting device that can adjust balance in a state in which a bell cup and an inner member are integrally assembled and can achieve an increase in yield and a reduction in the number of manufacturing steps. A rotary atomization painting device including a rotary atomizer head configured to rotate to atomize paint, the rotary atomizer head having: a bell cup that is formed into a bell shape to cause paint to be formed into a thin film; and an inner member that is arranged inside the bell cup and forms a paint reservoir, the inner member having a plurality of weight mounts on which weights are selectively mountable.

An improved cleaning device for an air conditioning condensing unit having a housing with a sprayer cleaning device therein which includes a rotatably disposed spray nozzle connected to a spray nozzle conduit which operably communicably connects to a hose coupling connection outside the housing, wherein the spray nozzle conduit rotates about a rotational axis. A method of cleaning the air conditioning condensing unit employs the sprayer cleaning device.

Improved wafer coating processes, apparatuses, and systems are described. In one embodiment, an improved spin-coating process and system is used to form a mask for dicing a semiconductor wafer with a laser plasma dicing process. In one embodiment, a spin-coating apparatus for forming a film over a semiconductor wafer includes a rotatable stage configured to support the semiconductor wafer. The rotatable stage has a downward sloping region positioned beyond a perimeter of the semiconductor wafer. The apparatus includes a nozzle positioned above the rotatable stage and configured to dispense a liquid over the semiconductor wafer. The apparatus also includes a motor configured to rotate the rotatable stage.

A material spreader assembly for the broadcast spreading of particulate material from the trailer hitch of a vehicle. A hopper for storing the particulate material is supported by a frame having a trailer hitch coupler for connection to the vehicle. A spreader including a spinner driven by an electric motor receives and disperses the particulate material. A control circuit receives electric current from the vehicle via a plug interface and a wiring harness and controls the operation of the spreader. A remote communicates user commands to the control circuit. The control circuit includes a motor control processor that controls a motor power relay and a motor driver to gradually ramp up the current supplied to the spreader for start up the spreader while preventing a high transient current draw spike. Component feedback sensors enable the motor control processor to provide an emergency shut off feature and warning signals.

Embodiments of the invention relate generally to disinfection and, more particularly, to methods, devices, and systems for disinfection of a space. In one embodiment, the invention provides a disinfecting system comprising: a disinfecting composition; and a device for producing a fog of the disinfecting composition, the fog comprising liquid droplets having diameters between about 0.5 micron and about 20 microns. In some embodiments, the invention includes a dehumidifying device for removing the fog of the disinfecting composition from the space.

A bowl for spraying a coating product, intended to be integrated into a rotary spraying apparatus for spraying a coating product. The spraying apparatus includes a turbine for rotating the bowl about an axis of rotation, and a body that defines the axis of rotation and includes shaping air ejection orifices arranged in a crown. The bowl includes a body which is centered in relation to an axis and which defines an inner radial surface for distributing the coating product to a spraying edge, as well as an outer radial surface. The outer radial surface of the bowl includes a deflector for at least partially directing a flow of cleaning product towards the crown of the body, the cleaning product flowing along the outer radial surface towards the spraying edge.

A liquid atomization device includes: an inlet; an outlet; and a liquid atomization chamber. The liquid atomization chamber is provided in an air passage between the inlet and the outlet. The liquid atomization chamber includes a rotary shaft, a pumping pipe, a collision wall, a reservoir, and a drain port. The rotary shaft is rotated by a rotary motor and is disposed in the vertical direction. The pumping pipe includes a lower portion having a pumping port and an upper portion fixed to the rotary shaft, and is rotated in coordination with rotation of the rotary shaft to pump up water through the pumping port and centrifugally discharge the water. The pumping pipe generates, inside the pumping pipe, a whirlpool in the water in the reservoir by the rotation, and forms, at the center of the whirlpool, a void providing communication between the pumping port and the drain port.

A device to distribute solids such as seeds, fertilizers, salts, or other granular materials through a machine for agricultural use or other similar uses, of the type that uses horizontal rotating plates or discs with spreader pallets, wherein access of the material to be distributed to the spreader pallets is tangential thereto, by use of a channeller downloaded in the central area of the disc. The device does not break the particles to be spread and, thereby, they maintain their original mass, which let us affirm that the working area is extended and the uniformity of the distribution is improved. Additionally, the tangential access of the material from the center of the rotating plate or disc, and with the same course of the pallets, gives an additional speed to the particles that allows to further increase the working area.
