An apparatus is disclosed for coating a surface that is movable relative to the apparatus with a layer of metallic particles or particles having a metal-like appearance and reflectivity, the particles adhering more strongly to the surface than to one another. The apparatus comprises at least one spray head for directly or indirectly applying to the surface a fluid stream within which the particles are suspended, a housing surrounding the spray head(s) and defining an interior plenum for confining the fluid stream, the housing having a rim adjacent the surface that is configured to prevent 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 the sprayed fluid and particles suspended in the sprayed fluid. In operation, the suction source extracts substantially all particles that are not in direct contact with the surface, so as to leave only a substantially single particle layer adhering to the surface on exiting the apparatus.

The invention relates to non-ferrous metallurgy and the electrolytic production of aluminium, and can be used for lining the cathode assembly of an electrolytic cell. The present method consists in laying materials while simultaneously distributing same over the surface of a base and levelling them at a height measured from the plane of the top edge of the shell of the cathode assembly of the electrolytic cell by gradually moving a device for installing unformed lining materials along the longitudinal axis of the cathode of the aluminium electrolytic cell. Said device is configured in the form of a bridge equipped with a mechanical drive for movement. The bridge has guides on which a frame is mounted for vertical movement, said frame having cassettes provided with gates with a mechanical drive. The technical result is reduced labour costs, healthier working conditions for operatives, and better quality installation of the base of an electrolytic cell.

An additive manufacturing device includes a recoater configured to push powder onto a build platform. The recoater defines an advancing direction for pushing powder. A first baffle is mounted to a first end of a leading edge of the recoater and a second baffle mounted to a second end of the leading edge of the recoater opposite the first end. Each of the first and second baffles includes a base mounted to the recoater, a first wall that extends obliquely ahead of and laterally outward from the base relative to the advancing direction, and a second wall opposite the first wall. The second wall extends obliquely ahead of and laterally inward from the base relative to the advancing direction. A volume is defined between the first and second wall with capacity to collect powder as the recoater advances.

An adjustable distributor apparatus (10) for dispensing a foam forming mixture comprising a main body (20) and adjustment plate, the main body featuring at least one inlet, one channel, and one outlet, the inlet, channel and outlet in fluid connection such that a fluid may pass through the inlet into the channel and exit from the channel through the outlet, and the outlet being coupled with at least one adjustment plate (40), the adjustment plate featuring at least a first face, a second face opposing the first face, and an outlet hole, enabling a seal between either the outlet of the main body or the second face of a second adjustment plate, and the outlet hole extending from the first face to the second face by way of a fluid connection through the adjustment plate.

Disclosed herein is a system for slurry coating leveling. The system includes a guide frame and a scrapper apparatus coupled to the guide frame. The scrapper apparatus includes a plurality of scrapper fingers aligned substantially parallel to each other. The system also includes a contour guide coupled to the scrapper fingers. The contour guide is configured to guide movement of the scrapper fingers across a surface of a component having a slurry coating. The scrapper fingers conform to a contour profile of the surface to level the slurry coating on the surface of the component.

A slurry scraping mechanism and an applying and scraping device used in an SG abrasive production process includes a scraping master support; a scraper, wherein the scraper is connected with the scraping master support through a suspension component such that the scraper 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 to the scraping master support, the torsion spring support shaft is movable up and down relative to the scraping master support, the torsion springs are clamped in a V-shaped plate, an end side of the V-shaped plate is connected with the scraping master support, and a side surface of the V-shaped plate is connected with the scraper.

Skin for dressing backlit vehicle interior parts comprising a perforated opaque decorative layer and a light transmitting material filling the holes wherein the light transmitting material is a reactive hotmelt adhesive which forms a base layer extended over the back side of the opaque decorative layer and comprising a central portion and a transition portion surrounding the central portion and several projections protruding from the central portion of the base layer and completely filling the through holes. Method and an installation for manufacturing said skin for dressing backlit vehicle interior parts.

An embodiment of the present invention provides a coating method, a coating bar head and a coating apparatus which enables coating in which changes in coating film thickness is less likely to occur, even when performing meniscus coating at a high speed. This coating method is a coating method including: supplying a coating liquid between a coating bar head and a substrate to form a meniscus; and moving the substrate, wherein a cross section of the coating surface of the bar head in the direction of coating, is a convex curve, and has bending points at both ends of the curve.

There is disclosed a method of printing onto the surface of a substrate, which method comprises i) coating a donor surface with a monolayer of particles, ii) treating the substrate surface 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, the donor surface returns to the coating station 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.
