Abstract:
A fluidized bed apparatus for applying a coating liquid onto the surface of particles includes a vertically disposed cylindrical product container having a peripheral wall, at least one cylindrical partition defining a centrally located up bed region and a peripherally located down bed region. The product container further includes an upper end connected to an expansion chamber and a lower end including an orifice plate having a plurality of openings for passage of fluidized air or gas. A nozzle is centrally located through the orifice plate and is adapted to generate a spray of coating liquid upwardly into the up bed. Particles located within the product container circulate upwardly through the partition and the coating liquid spray, between the up bed and the down bed. A plurality of inwardly directed discharge jets are positioned along the periphery of the product container and generally adjacent to the orifice plate. A source of pressurized air or gas is connected to the plurality of discharge jets and provide a radially inwardly directed flow of air or gas through the particles of the down bed so that the particles located adjacent to the peripheral wall of the product container are displaced radially inwardly along the orifice plate towards the nozzle and the up bed. A partition having an outer wall surface and an outwardly directed flared lower end defining a lower rim. The partition further includes an inwardly and upwardly directed ramp surface extending between the lower rim and the up bed. The improved partition encourages particles located within the down bed adjacent to the outer wall surface to move outwardly away from the up bed until reaching the lower rim, at which point the particles are atraumatically and gradually directed inwardly and upwardly along the inwardly and upwardly directed ramp surface into the up bed to continue the coating process. A nozzle ramp is provided around the nozzle. The nozzle ramp is generally cusp shaped and includes nozzle-ramp surface. The nozzle ramp is centrally positioned around the nozzle and is directed upwardly towards the partition so that the nozzle-ramp surface directs particles moving generally horizontally across the orifice plate from the down bed upwardly into the partition and the up bed. The nozzle ramp may further include air passages for passing fluidized air upwardly to the nozzle-ramp surface. A central discharge assembly is provided at the lower end of the product containers for emptying particles from the machine. Air is preferably discharged from the manifold during the emptying process to help direct particles towards the discharge assembly.
Abstract:
An apparatus is provided for coating a continuously advancing article. The apparatus includes a housing defining a spray chamber having an inlet end and an outlet end. Walls in the spray chamber form an inlet buffer zone adjacent the inlet end, an outlet buffer zone adjacent the outlet end and a spraying zone between the inlet and outlet buffer zones. A conveyor transports articles to be coated through the spray chamber. A plurality of spray guns are mounted on the housing to substantially surround an article on the conveyor transported through the spraying zone. The spray guns are adapted for spraying an ultraviolet curable coating composition. The spray guns are mounted substantially entirely outside the spraying zone, with only nozzle portions of the spray guns located inside the spraying zone.

Abstract:
A coating device for coating a coating solution on a web has a roller and a weir which partially constructs a solution store space. In the solution store space the coating solution is stored. When the web sequentially moves in a direction, the roller rotates and the solution in the solution store space is supplied on the web. Thereby a part of the solution overflows the weir such that another part of the solution may remain on the web to have a constant width in a widthwise direction of the web. A drying device has plural drying zones in which the web is fed after the coating of the coating solution. One of the drying zones is neighbored to the coating device. A top of the plural drying zones is constructed of a blow regulation member so as to confront to the solution on the web. The blow regulation member has holes through which is exhausted a gas evaporated from the layer of the solution on the web.

A disclosure is directed to a coating method of a liquid on the surface of a member during a coating head and the member are moved relatively, thereby forming a coating film. An improvement resides in that a process of mixing plural kinds of coating liquid with one another, and a process of supplying the resultant mixed liquid to the coating head are substantially, simultaneously carried out. The method is used, for example, in producing a color filter of a liquid crystal display device.
Abstract:
A system for distributing liquid coatings such as epoxys and urethanes onto a substrate base. The system includes a hose for transporting the liquid coating material from a storage container to a spray gun. A heating element within the hose heats the liquid coating material to facilitate transport and distribution of the liquid coating material. The heating element contacts the liquid coating material and can be activated by electrical resistance heating or by other techniques. By placing the heating element directly in contact with the liquid coating material, long line cooling losses are avoided, and heating energy is efficiently transferred to the liquid coating material immediately before distribution. Sensors along the hose length can monitor the liquid coating material temperature at different positions, and heating control over different hose sections can be controlled to efficiently accomplish optimum liquid coating material temperature before the liquid coating material is sprayed. Two part liquid coating materials can be separately transported through distinct, internally heated hoses and combined with a mixer at a position near the spray equipment.
Abstract:
A deposition system is used for depositing particles onto a substrate, such as a wafer in a deposition chamber. The particles are carried in an aerosol that is generated an atomizer that includes an impaction plate for removing large particles before the aerosol is discharged, and which has an output that is provided through a particle classifier to the deposition chamber. Various branches of flow lines are used such that the aerosol that has classified particles in it, is mixed with a clean dry gas prior to discharge into the deposition chamber, and selectively the aerosol can be directed to the deposition chamber without having the particles classified. The lines carrying the aerosol can be initially connected to a vacuum source that will quickly draw the aerosol closely adjacent to the deposition chamber to avoid delays between deposition cycles.
