A spin coater that can be used to apply multiple coating compositions over an optical substrate, is described. The spin coater includes, a coater bowl configured to collect excess coating material expelled from an optical substrate being coated, a rotatable chuck configured to receive and rotate the optical substrate in the bowl during coating, a plurality of coating reservoirs, each containing a coating material, and an indexable coating reservoir platform containing the plurality of reservoirs and configured to index a selected reservoir into a dispensing position above the coater bowl. The spin coater can include or have associated therewith at least one curing station, in which each curing station is independently configured to cure at least partially at least one applied coating material. Each curing station can include at least one of, a thermal curing station, a UV curing station, and/or an IR curing station.

Abstract:
A liquid dispenser gun (14) for mixing first and second liquid components of a two-component mixture (1 1 ) and dispensing the two- component mixture (1 1 ) includes a gun body (78), a mixing manifold (82), and a nozzle plate (84). The gun body (78) includes a gun body fluid passage (94) in fluid communication with gun body inlets (38, 50, 56) and the mixing manifold (82). The gun body fluid passage (94) is a groove in a bottom surface (79) of the gun body (78) having a generally non-linear shape such that the second component has a generally laminar flow through the gun body fluid passage (94) while a flushing component may be introduced in the gun body fluid passage (94) in a manner to produce turbulence in the flushing component.

The laminated nozzle includes a first end plate (112) having a first fluid inlet (126) and a second fluid inlet (130), a second end plate (114), a plurality of nozzle plates (116, 118, 120, 122, 124) positioned and clamped between the first end plate and the second end plate, a first fluid conduit (128) in fluid communication with the first fluid inlet formed in one or more of the nozzle plates, a second fluid conduit (132) in fluid communication with the second fluid inlet formed in one or more of the nozzle plates, a first orifice (134) in fluid communication with the first fluid conduit formed in one of the nozzle plates, and a second orifice (136) in fluid communication with the second fluid conduit formed in the same nozzle plate as the first orifice. The laminated nozzle assembly minimizes the number of nozzle plates and includes no more than eight, and preferably no more than five nozzle plates.
Abstract:
A system of pointillist painting comprises an automated 3-D positioning system disposed proximate a painting surface, a colorant dispenser coupled to the gantry structure and having a dispensing tip in fluid communication with a colorant chamber, the gantry structure operable to move the colorant dispensing tip to a specified position of the painting surface, where the colorant dispenser is operable to apply a specified amount of a colorant to the painting surface and creating a dot having a two-dimensional coverage and three-dimensional profile at the specified position. The colorant dispenser further comprises a piston disposed in the colorant chamber, and a push rod coupled to the piston operable to advance the piston toward the dispensing tip to exude the specified amount of colorant onto the painting surface.
Abstract:
L'invention se rapporte à une installation pour le dépôt d'un film de particules ordonnées (4) sur un substrat en défilement (38), l'installation étant conçue pour permettre le dépôt, sur le substrat, d'un film de particules ordonnées s'échappant par la sortie de particules d'une zone de transfert présentant une première largeur (L1). Selon l'invention, l'installation comporte en outre un dispositif accessoire (100) en forme de tête de dépôt, prévu pour obturer ladite sortie de particules et conçu pour permettre le dépôt, sur le substrat (38), d'un film de particules ordonnées s'échappant par une extrémité (62) d'un canal de transfert de particules (56) de cette tête de dépôt, cette extrémité présentant une seconde largeur (L2) strictement inférieure à la première largeur (L1).
Abstract:
A dispensing system for dispensing a slurry or glaze for making or printing products of the ceramic industry comprises a plurality of reservoirs (2) suitable for containing a respective fluid mixture or glaze (S) and at least one dispenser (3) associated with the reservoirs (2) and equipped with at least one outlet (3a) for dispensing the fluid mixture (S). The system further comprises at least one mixer (6) operatively interposed between the reservoirs (2) and the dispenser (3), and configured to receive the fluid mixture (S) from each reservoir (2) and to send a mixed fluid (F) to the dispenser (3), adjusting means (9) operatively interposed between each reservoir (2) and the mixer (6), and a control unit (15) associated with the adjusting means (9) and configured to drive them so as to adjust the mixing ratio (R) between the flow rates of fluid mixtures (S) into the mixer (6) depending on a reference signal related to a predetermined hue of the mixed fluid.
