  • Patent number: 6684527
    Abstract: A wheel includes a peripheral outer wall onto which are sequentially loaded veneer panels. The panels are held in place by cable runs against a heated outer surface of the wheel outer wall. Drying of the veneer panels occurs during wheel rotation. A heated fluid medium such as hot oil flows through an annular chamber of the wheel. A series of inlet conduits supply the annular chamber with the heated medium while return conduits return same to a heat source. Multiple tensioned runs of cable confine each panel in place during wheel rotation. A modified form utilizes a continuous screen for panel retention. A drive system imparts rotation to the wheel by powered components in contact with the wheel periphery. A panel pre-heater and jet dryers are supplemental heat sources.

  • Publication number: 20040010930
    Abstract: A centrifugal processor includes an elongated inlet and outlet in fluid communication with a rotor housing having an eccentric bowl. A rotor having fan blades and adapted to hold flat media is rotatably disposed within the rotor housing. An intake gate is pivotably mounted to the rotor housing to swing about the rotor into a closed position during a rinse mode and into an open position during a drying mode. The gate has a wedge that is designed to almost contact the rotor when the gate is in the open position for drying. The geometry of the elongated inlet, outlet, and eccentric bowl, in combination with the design of the rotor and that of the intake gate, work together to create a cross flow fan having a flow path across the flat media and one that exposes the flat media to large volumes of incoming air only once.

  • Publication number: 20030177659
    Abstract: Liquid for prevention of substrate drying is supplied into a processing chamber so that a pool of the liquid is created as an anti-drying atmosphere in advance inside a processing chamber, and substrates, as they are dipped in the pool, are kept on stand-by in a substrate board. In this manner, air drying of the substrates which are kept on stand-by is prevented. When the number of the substrates in the substrate board reaches a certain number, the anti-drying atmosphere is removed from the processing chamber, which is followed by introduction of an SCF into the processing chamber and supercritical drying (high pressure drying) of all of the plurality of substrates inside the processing chamber, namely, batch supercritical drying.

  • Patent number: 6270584
    Abstract: Method and apparatus for cleaning and/or drying objects that may have been wetted or contaminated in a manufacturing process. The objects are submerged in a rinse liquid in an enclosed chamber, and aerosol particles from a selected liquid are introduced into the chamber above the rinse liquid surface, forming a thin film on this surface. As the rinse liquid is slowly drained, some aerosol particles settle onto the exposed surfaces of the objects, and displace and remove rinse liquid residues from the exposed surfaces by a “chemical squeegeeing” effect. Surface contaminants are also removed by this process. Chamber pressure is maintained at or near the external environment pressure as the rinse liquid is drained from the chamber. Inert gas flow is employed to provide aerosol particles of smaller size and/or with greater dispersion within the chamber. Continuous filtering and shunt filtering are employed to remove most contaminants from the selected liquid.

The isopropyl alcohol is then evaporated, whereby the wafers are dried.

  • Patent number: 6195911
    Abstract: A process and apparatus for the gelatin coating of medicaments which includes a continuous conveyer system to advance a plurality of pallets through a loading station, at least one dipping station, at least one dryer station, a reorientation station and an unloading station. Medicaments to be coated are loaded into pallets at the loading station and advanced to the first dipping station where a vacuum is applied to secure the medicament to the pallet. The pallet is inverted and a first portion of each of the medicaments is dipped into a coating mixture. The pallet is then returned to its upright position, the vacuum is removed and the coating is dried. The medicaments are then transferred from the first pallet to a second pallet by a reorientation mechanism. The second pallet is then advanced to a second dipping station which operates in the same manner as the first dipping station.

  • Patent number: 6192604
    Abstract: A paint drying system for drying painted motor cars, particularly those cars painted with water-born paints. The system includes a spray booth (2) which is supplied with heated air which flows in a downdraft from an upper inlet (32) to a lower outlet (44) and also from wall-mounted air jets. The air from the air jets disrupts the downdraft causing air turbulence within the spraybooth (2) which accelerates drying of the painted cars. In a preferred embodiment, the spraybooth has corner mounted air jets.

  • Patent number: 6189238
    Abstract: A portable purge system for transporting materials, such as semiconductor wafers used in the manufacture of ICs, comprises a carrier having compartments for releasably receiving and enclosing the materials therein. The carrier is flooded with an inert gas such as nitrogen so as to adsorb the nitrogen on the surface of the materials, dilute contaminants, and purge the contaminants from the carrier. The carrier and the flooding means are mounted in a transport case. A humidifier is connected to the flooding means so that the materials will adsorb water and thereby further resist adsorption of hydrocarbon contaminants.

  • Patent number: 6151794
    Abstract: An apparatus for heat treating an object and specifically a substantially flat object described. The apparatus may be a hot plate post-baking apparatus for heat treating a substantially flat object such as a photomask used in a semiconductor photolithographic process. The apparatus is provided with an upper heat reflector plate that is equipped with upwardly curved edge portions such that the amount of heat reflected by the reflector can be controlled and the center region on the substantially flat object can be temperature compensated for achieving more uniform temperature profile across the entire surface of the mask. By utilizing the heat reflector plate in a post-baking apparatus, the normally observed 5.degree. C. temperature difference across a mask surface is substantially eliminated.
