Abstract:
A system for electrostatic painting of metallic manufactured articles comprises a conveyor system for a plurality of hangers (18) designed to carry the metallic manufactured articles (19) and a painting device (16) for the manufactured articles (19) and an oven (15) traversed by said conveyor system. The conveyor system comprises a first conveyor (11) for accumulation outside of the oven (15) for loading of the hangers (18), a second conveyor (13) for accumulation outside of the oven (15) for unloading of the hangers (18), a third conveyor (12) for accumulation inside the oven (15), and a fourth conveyor (14) connecting the first three conveyors (11, 12, 13) for transfer of the hangers (18) among them. A method for electrostatic painting of metallic manufactured articles making use of the above mentioned system.
Abstract:
A method of making printed circuit boards, particularly 3-dimensional circuit boards, wherein a surface layer of micron sized hollow spheres, beads or spacers (12) are ruptured or fractured by a laser (17) in a pattern defining the electrical circuit (16). The circuit pattern is thermally sprayed with molten copper particles. The molten copper particles shape themselves to the nooks, crannies and undercuts of the fractured spheres or beads to mechanically lock the electrical circuitry to the board. The current carrying capacity can be adjusted by the thickness of the sprayed metal. The overspray does not adhere to smooth non porous surfaces (105) adjacent the fractured spheres or beads.
Abstract:
prolongador isolado para pulverização com assistência eletrostática é descrito um prolongador isolado para pulverização com assistência eletrostática instalado na barra de pulverização de um equipamento pulverizador e posicionado adjacente a um bico hidráulico (20) que atomiza a calda de pulverização, dito prolongador (10) dotado de uma haste interna isolada (12), com sobrecapa (111), ambas aletadas, para a passagem do cabo de alimentação (30) e o posicionamento do dispositivo elétrico encapsulado (13) que alimenta o eletrodo de indução (151) com alta tensão, que circunda o bocal (21) do bico hidráulico (20), resultando em ruptura dielétrica e indução de cargas positivas ou negativas nas gotas atomizadas, eliminando ou diminuindo o dreno de correntes elétricas entre o eletrodo indutor (151) e o terra na barra de pulverização (100), bem como dificultando a fuga de corrente elétrica através do cabo (30) pelo contato com qualquer parte da estrutura da máquina.

Abstract:
Disclosed is a method of applying particles to a coated backing. A first layer of particles is created over a second layer of particles on a support surface and the first layer of particles is different in at least one property from the second layer of particles. A coated backing is positioned above the first and second layer of particles. An electrostatic field is applied simultaneously to the first and second layer of particles such that the first layer of particles closer to the coated backing are preferentially attracted to the coated backing first before the second layer of particles.
Abstract:
Apparatus and related methods align magnetic flakes in a carrier, such as an ink vehicle or a paint vehicle to create optically variable images in a high-speed, linear printing operation. Images can provide security features on high-value documents, such as banknotes. Magnetic flakes in the ink are aligned using magnets in a linear printing operation. Selected orientation of the magnetic pigment flakes can achieve a variety of illusive optical effects that are useful for decorative or security applications.
Abstract:
A vibrator vibrates a solution containing a sample to atomize it into fine particulate substance with its activity held, a high-voltage-applied wire electrifies the solution and/or the atomized fine particulate substance to dry them in floating, and the particulate substance is deposited on an earthed substrate by an electrostatic force to immobilize it with its activity held.
Abstract:
A molten metal spray-depositing apparatus for atomizing a stream of molten metal into metal particles in a divergent spray pattern of higher mass density at an upstream leading peripheral portion of the spray pattern, relative to the direction of movement of a substrate, than either of a center region or downstream trailing peripheral region of the pattern. The atomizer (34) may generate one-side sheer force for breaking up its metal stream. Alternatively, the atomizing device may be in the form of an annulus (35, 50, 64, 80, 100, 120, 140, 160) of varying configurations with plenum chambers and outlets so arranged that a divergent conical spray pattern is produced having central axes inclined with respect to the vertical axes of the molten metal stream in a direction downstream of the moving substrate upon which the spray material is deposited. An alternative form of the spray depositing apparatus employs a magnetic fuel-generating nozzle (234, 248) which eliminates the use of gas. Other forms of a gasless nozzle (334, 336) have a configuration for confining and imparting mechanically an angular momentum to the molten stream to break it up.
Abstract:
A method for producing a columnar or cylindrical metal automotive part whose outer circumferential surface includes a portion to be coated with paint and a portion to be uncoated therewith includes the following processes: (1) a process of providing a convergent nozzle-shaped covering jig which covers an outer circumferential surface of the columnar or cylindrical part at an axial end thereof and covers the portion to be uncoated with the paint, with a gap formed between the covering jig and the outer circumferential surface of the part; (2) a process of discharging a gas from the gap toward an end of a nozzle of the covering jig with the columnar or cylindrical part being rotated; (3) a process of sticking a film-forming substance to the columnar or cylindrical part from an axial side surface thereof.
