The embodiments disclose an apparatus including a dispenser having an elongated compartment configured to contain a liquid solution, a liquid solution contained in the elongated compartment configured to suspend solid nanoparticles in an evaporative liquid, a dispenser handle configured to twist to push a predetermined amount of the liquid solution from the elongated compartment out of an open tip orifice, and at least one applicator tip insertable into the tip orifice configured to receive from the elongated compartment the predetermined amount of the liquid solution to spread over a user's mobile device glass screen.

A system for dispensing a substance in a form of a bead on a surface in a progression direction includes a dispenser having: a leading edge, a contact portion comprising two contact points with the surface, and a trailing edge that extends between the two contact points and terminates therein. The system is configured to move the dispenser along a virtual travel plane, which is parallel to the path and passes through the two contact points, while maintaining the contact portion in communication with the surface as the substance is being dispensed. The system is also configured to monitor a leading portion of the bead and to generate a signal responsive to at least one characteristic of the leading portion, wherein the leading portion is located ahead of a portion of the leading edge in the progression direction along the path. The system is further configured to control, responsive to the signal, at least one of a speed of the dispenser along the path or a flow rate of the substance to the dispenser to provide a substantially uniform cross-sectional shape of the bead along the path.

There is disclosed a print construction comprising: (a) a printing substrate having an image-receiving surface; (b) a receptive layer, at least partially covering said image-receiving surface, and having a particle reception surface distally disposed to said image-receiving surface, said receptive layer optionally having a thickness of at least 1000 nanometer (nm); and (c) a plurality of individual particles adhered to said particle reception surface, and forming a monolayer thereon, the features of which are described herein.

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.

A resin protection member forming apparatus includes a stage having a resin placement surface on which a particulate thermoplastic resin is to be placed. The stage includes a Peltier device, a DC power source, and a switch. The Peltier device is disposed inside the stage and has an upper surface, which is parallel and close to the resin placement surface, and a lower surface, which is far from the resin placement surface. The DC power source supplies a DC current to the Peltier device. The switch changes a direction of the DC current to be supplied to the Peltier device, between a first direction to heat the upper surface of the Peltier device and a second direction, opposite to the first direction, to cool the upper surface of the Peltier device.

There is disclosed a method of printing onto the surface of a substrate, which method comprises i) coating a donor surface (12) with a monolayer of particles, ii) treating the substrate surface (80) to render at least selected regions tacky, and iii) contacting the substrate surface with the donor surface to cause particles to transfer from the donor surface only to the tacky regions of the substrate surface. After printing on a substrate (20), the donor surface (12) returns to the coating station (14) where the continuity of the monolayer is restored by recovering with fresh particles the regions of the donor surface exposed by the transfer of particles to the substrate.

An apparatus for coating a donor surface that is movable relative to the apparatus with a layer of thermoplastic particles, the particles adhering more strongly to the surface than to one another. The apparatus comprises an application device to apply to the donor surface a fluid stream within which the particles are suspended, a housing surrounds the application device forming an interior plenum for confining the fluid stream, the housing prevents egress of particles from a sealing gap defined between the rim of the housing and the surface to be coated, and a suction source connected to the housing to extract from the plenum excess fluid and particles. In operation, the suction source extracts substantially all particles that are not in direct contact with the donor surface, leaving substantially a single particle layer adhering to the donor surface upon exiting the apparatus.

A die head apparatus is provided with a front blade, a rear blade, a center blade, and an internal impurity removal space. The front blade and the center blade are configured to form a pool of a slurry. The internal impurity removal space is positioned between the center blade and the rear blade. A distance separating the rear blade and the substrate is set to be smaller than the distance separating the center blade and the substrate.

Disclosed is a slurry screeding mechanism used in the production process of the SG abrasive. The slurry screeding mechanism includes a screeding main support; a screeding plate which is connected with the screeding main support through a suspension component so that the screeding plate is suspended, and a damping spring is arranged in the suspension component; and a torsion spring adjusting component, wherein the torsion spring adjusting component includes a plurality of torsion springs supported by a torsion spring support shaft; the torsion spring support shaft is fixed on the screeding main support; the torsion spring support shaft can move up and down relative to the screeding main support; the torsion springs are clamped in a V-shaped plate; an end side of the V-shaped plate is connected with the screeding main support; and a side surface of the V-shaped plate is connected with the screeding plate.

A particulate-incorporating attachment for a drop spreader is provided that includes a two-portion mount bracket, an implement holder, and a rake/brush and optionally includes wheels. The bracket portions are connected to form a mount bracket over the rest brace of the drop spreader. The mount bracket mounts the implement holder, which supports the rake/brush in a suitable position to assist in the incorporation of infill material into the space between the grass tufts of synthetic turf or to assist in the incorporation of other dropped particulates into synthetic or natural turf or onto the ground.
