Abstract:
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 1401 for directly or indirectly applying to the surface 12 a fluid stream within which the particles are suspended, a housing 1403 surrounding the spray head(s) 1401 and defining an interior plenum 1406 for confining the fluid stream, the housing having a rim 1404 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.
Abstract:
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.

Abstract:
This invention relates to compositions and methods related to biocompatible conductive inks. In a preferred embodiment the inks are printable onto biocompatible substrates and are used in the creation of biocompatible medical devices, in general, the inks comprise a plurality of particles. In one embodiment, the particles have a particle surface and an agent on the particle surface, the agent configured to prevent the particles from agglomerating when the particles are in a solution, the agent also configured to allow adjacent particle surfaces to be in contact when the particles are not in the solution due to an opening in the agent.
Abstract:
A coated cold-rolled steel substrate comprising a water-reducible coating composition, which coating composition comprises water, an organic solvent, a silane as binder, a coating additive and a metal, wherein the metal is a metal particle or a metal alloy particle having an aluminium content greater than 50 weight % and a balance of less than 50 weight % of a non-aluminium metal, and wherein the coating has a wet film thickness in the range of 6 μm to 90 μm.
Abstract:
A device and method for imparting indicia to a wet-film of resinous liquid and magnetically positional particles located on a substrate. The device employs a planar magnet abutting a planar metal sheet imaging indicia formed thereon. The planar metal sheet interacts with the magnetic field communicated to the wet-film to form indicia into the wet-film through migration and reorientation of the particles along the lines of the field. The letters, numbers, logos, or other images formed as indicia may be formed such that when viewed they appear three dimensional.
Abstract:
A metallic tone glitter paint film is formed by applying sequentially a first base metallic paint, a second base glitter paint in which very small scale- like pigment or very small scale-like pigment and aluminum pigment is compounded and a clear paint, baking and hardening. The metallic paint contains (A) aluminum pigment of average particle diameter D50 from 13 to 40 m and average thickness from 0.5 to 2.5 µm, (B) aluminum pigment of average particle diameter D50 from 13 to 40 µm and average thickness from 0.01 to less than 0.5 m and (C) aluminum pigment of average particle diameter D50 from 4 to less than 13 µm and average thickness from 0.01 to 1.3 µm, and the ratio (A/B) by mass of the solid fractions of the aluminum pigments (A) and (B) is from 10/90 to 90/10.
