In one aspect, a method for permeating color into components includes the step of placing substrates inside a carrier. The method includes the step of placing the carrier inside an ultrasonic cleaning tank of an ultrasonic cleaning machine. The method includes the step of performing an ultrasonic cleaning in the ultrasonic cleaning tank. After the ultrasonic cleaning, the method transports the carrier with a robotic arm to a washing tank. The method includes the step of inserting, with the robotic arm, the carrier into the washing tank and neutralizing a substrate with water in the washing tank. The method includes the step of feeding warm water into a channel of the washing tank up to a specified level. The method includes the step of steaming the washing tank for a specified steaming time.

In an example, a method including dispensing a liquid onto a first portion of a surface of a substrate and dispensing a solution comprising colloidal spheres onto a second portion of the surface of the substrate. The method additionally includes agitating the colloidal spheres to disperse the colloidal spheres along the first portion and the second portion of the surface of the substrate and directing air flow above the colloidal spheres inducing rotation of the colloidal spheres. In another example, a method includes positioning a retaining ring on a surface of a liquid above a substrate below the surface of the liquid and dispensing a solution comprising colloidal spheres onto the surface of the liquid within a surface area of the retaining ring. The method further includes agitating the surface of the liquid and the colloidal spheres to disperse the colloidal spheres along the surface area of the retaining ring.

A sector roll dipping plant for impregnating rotating components (1) of electric machines in the form of stators and rotors has a roll dipping tank or roller immersion tray (6) that is divided into sectors having impregnating agent inlets (11) which are separated from one another by bulkheads or partition walls (7). At least one sealing element (8) connected to one of the partition walls (7) is in contact with the rotating component (1). A method for impregnating a rotating component (1) (such as a stator or rotor of an electric machine) uses the sector roll dipping plant to cause only the grooves of the rotating component to be soaked with impregnating agent while laminations on the outer jacket surface of the rotating component remain clean.

Technologies are generally described to increase a surface smoothness of a 3D printed article implementing a water-based treatment using layer by layer (LBL) deposition. An initial 3D printed article having an anionic surface may be treated with a first aqueous solution comprising at least one polycation that may bind to the anionic surface to produce a first treated surface, which may be rinsed with water to remove the first aqueous solution. The first treated surface may be treated with a second aqueous solution comprising at least one anionic microparticle that may bind to the polycation to produce a final 3D printed article having a second treated surface, which may be rinsed with water to remove the second aqueous solution. The bound polycation and anionic microparticle may be present as a single layer in the final 3D printed article that may act as a conformal coating to increase the surface smoothness.

The particle impregnating device includes a placing body for placing a nonwoven fabric having a surface on which particles are sprayed; a vibrating member which is provided above the placing body and extends in the width direction of the nonwoven fabric placed on the placing body; a vibrator which applies ultrasonic vibration to the vibrating member; a lifting mechanism which lifts up and down the vibrating member; and a moving mechanism which relatively moves the nonwoven fabric and the vibrating member in a surface direction orthogonal to the width direction of the nonwoven fabric. When the nonwoven fabric and the vibrating member are relatively moved by the moving mechanism, the vibrating member is lowered by the lifting mechanism, so that the nonwoven fabric is pressed and compressed by the vibrating member and ultrasonic vibration is applied to the vibrating member by the vibrator.

According to an embodiment, an apparatus for applying hydroxyapatite to a nonwoven fabric includes a tank, a shower head, an ultrasonic wave generator, and a drying section. The tank stores suspension containing hydroxyapatite. The shower head jets the suspension against the nonwoven fabric in the suspension in the tank. The ultrasonic wave generator emits ultrasonic waves against the nonwoven fabric. The drying section dries the nonwoven fabric in a wet state removed from the suspension in the tank.
