The invention relates to the field of the protection of security documents such as for example banknotes and identity documents against counterfeit and illegal reproduction. In particular, the present invention provides processes for magnetically transferring one or more indicia into a not yet hardened coating layer made of a coating composition including platelet-shaped magnetic or magnetizable pigment particles so as to produce optical effect layers (OELs) as anti-counterfeit means on security documents or security articles or for decorative purposes.

A repaired area on a work surface is presented. The repaired area includes a repairboundary. Within the repairboundary, the work surface has a repair texture and, outside of the repair boundary, the work surface has a work surface texture. The repaired area also includes a repair depth distribution within the repair boundary and a concealing feature. The repaired area is a result of a robotic repair executed on the work surface to remove a defect.

A positioning jig assembly includes a positioning main body with holes into which electronic component bodies are respectively press-fit, a first and a second guide bodies disposed to be superimposed on the positioning main body in a planar view. First through-holes are formed in the first guide body. Second through-holes formed in the second guide body guide the electronic component main bodies to the first through-holes. The first through-holes provisionally position the electronic component main bodies. When height in the first direction of the electronic component main bodies is represented as H, lengths of the first through-hole and the second through-hole are respectively represented as L1 and L2, and depth of the hole is represented as D, L1<H<D+L1+L2 and D<H hold.

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.

Methods and systems for coating metal substrates are provided. The methods and systems include sequential application of low flow and high flow powder coatings followed by a single heating step to provide a cured coating. The methods and systems include a marker that allows coating uniformity to be monitored and assessed during application. The described methods provide coatings with optimal surface smoothness and edge coverage.

Disclosed is a resinous adhesion promoter comprising (a) a random copolymer having first and second constitutional monomeric units, the first units comprising halogen and/or a pendant organic group having six or more carbon atoms and the second monomeric units comprising an active hydrogen-containing functional group; and (b) one of either (i) a non-reactive adhesion promoter or (ii) a reaction mixture comprising a first component and a second component, at least one of the first and second components having functional groups being reactive with the active hydrogen-containing functional groups of the random copolymer.

The invention relates to the use of coatings of nanoscale SiO.sub.2 particles in water-carrying cooling systems to prevent abrasive corrosion and depositions as well as to a method for the production of such a coating.

Impregnation plant for internally hollow cylindrical components (stators) of electric motors including working stations arranged linearly and sequentially, managed and controlled by central processing unit; and a plurality of motor-driven elements to impart rotatory motion, in both directions of rotation, and tilting motion, in both directions respective to a predefined plane, to each component mounted onto a respective support device when such support device is inserted into the plant working stations. Each support device has a spring collet in turn has blocks clamping the component onto the inner diameter of its respective cylindrical body. Each spring collet entirely crosses the component cylindrical body to rest on both of its respective circumferential ends. An impregnation method for electric motor components using the impregnation plant, wherein the component is rotatable in both directions about a support device predefined axis, and tiltable respective to a predefined plane of such support device.

Antibacterial coatings and methods of making the antibacterial coatings are described herein. A first branched polyethylenimine (BPEI) layer is formed and a first glyoxal layer is formed on a surface of the BPEI layer. The first BPEI layer and the first glyoxal layer are cured to form a crosslinked BPEI coating. The first BPEI layer can be modified with superhydrophobic moieties, superhydrophilic moieties, or negatively charged moieties to increase the antifouling characteristics of the coating. The first BPEI layer can be modified with contact-killing bactericidal moieties to increase the bactericidal characteristics of the coating.

A method for manufacturing a structure on a surface of a workpiece (1) is disclosed, the method having the following steps: applying a liquid base layer (2) onto the surface of the workpiece (1); spraying on at least one droplet (3) into the not yet congealed base layer (2), wherein the at least one droplet (3) at least partially, preferably completely, penetrates into the base layer (2); fixing the base layer (2); and at least partially removing the at least one droplet (3). Further, a second method having the following steps is disclosed: spraying on at least one droplet (3) onto the surface of the workpiece (1); applying a liquid base layer (2) onto the surface of the workpiece (1), wherein the base layer (2) flows around the at least one droplet (3) and preferably at least partially covers the at least one droplet (3); fixing the base layer (2); at least partially removing the at least one droplet (3). Finally, a device for performing the methods is disclosed.
