With Gas Or Vapor Circulation For Contact With Treated Material Patents (Class 34/629)
  • Patent number: 9746235
    Abstract: Infrared air float bar for use in floating and drying a continuous planar web of a material in a dryer. Direct radiated or reflected infrared electromagnetic energy from an infrared light source in a removable channel assembly accelerates drying, or evaporation of solvents, or curing of web material passing in proximity to the bar, either by infrared electromagnetic energy, or in combination with convention airflow. The infrared source is cooled by pressurized air passing through an interior portion of the removable air bar channel assembly, and the air is further conducted into fluid contact with the web in an air gap between the emitter and web to promote convective heat transfer and to contribute to the air pressure field supporting web flotation. The removable channel assembly is configured for replacement of the infrared emitter and to allow the setting of the pressurized cooling air flow to the optimum level.

  • Patent number: 8656605
    Abstract: Described herein are devices and methods for reducing thermal stresses in a rotating, foraminous thin-shelled roll for drying permeable and semi-permeable webs by blocking axial flow of heated air through an axial channel formed between two corrugated layers in the shell. The axial channels extend between spaced-apart, parallel end members each having an inner face, and a plurality of alternating straight thin divider strips and bent thin strips extending axially between and evenly-spaced around the circumference of the inner faces of the end members to form an annular cylinder with radial channels therethrough. Affixing at least one impermeable insert into a radial channel so that it extends through the radial channel and across at least a portion of the faces of the two tiers of bent strips blocks the axial channel therebetween and prevents the passage of air therethrough to the end member.

  • Patent number: 7861437
    Abstract: The present invention relates to novel dryer systems that incorporate two-stage processes for heating air for drying a traveling web. The present invention is operable within a drying system having a drying hood containing a dryer. The drying hood receives heated air through an intake and expels system air through an exhaust. The portion of system air that is maintained in the system is divided into two portions and directed into separate parallel conduits for two-stage heating that results in greater temperature uniformity and efficiency within the system. One loop includes a mixing chamber for the initial mixing of system air with the combustion products of a burner. A second loop includes an injection chamber that receives the initially mixed air and injects it into the other portion of the system air, resulting in greater temperature uniformity within the drying hood and increased operating efficiency for the entire system.

    Abstract: A microcavity-forming system for making microcavities in a wire (especially a tungsten filament wire). The system has a coating station receiving the wire and applying a polymer coating to the wire. A mask-forming station receives the polymer-coated wire and blows moist air over it to form air bubbles which result in holes in the polymer coating, thereby creating a mask. An etching station receives the wire, as coated with the polymer mask, from the mask-forming station and etches the wire through the holes in the polymer mask to form microcavities in the wire. A stripping station receives the wire from the etching station and removes the polymer mask from the wire, leaving the wire with microcavities. Processes of forming microcavities in a wire and, more generally, of making an etching mask having arrays of holes and conforming to substantially any surface, including an arbitrary curved surface, are provided.

  • Patent number: 6591518
    Abstract: A method and apparatus for is provided for supporting and connecting drier cassettes of an air knife type of drier. The drier cassettes exhaust air on traveling printed matter and are joined and supported by expander units that also exhaust air on the printed matter to increase drying efficiency. Gas or air is supplied to either the drier cassettes or the expander units or both and window apertures may be provided to allow the gas to communicate between the drier cassettes and the expander units. The relative exhaust pressures of the expander units and the drier cassettes may be regulated to create a pressure gradient on the printed matter as it travels through the exhaust so that the path of the paper suffers from less disruption.

  • Publication number: 20030061730
    Abstract: A substrate feed chamber that is equipped in a substrate processing apparatus is provided. The substrate feed chamber has a storage tray capable of storing simultaneously three or more substrate holding trays that hold substrates in a vertical or substantially vertical condition and a horizontal movement mechanism that moves horizontally the storage tray with respect to the substrate feed position in order to effect feeding-in or feeding-out movement of the substrate holding tray between any of the chambers of a group consisting of processing chambers and load lock chambers and, in addition, if required, has a rotary movement device that rotates the storage tray. Improvement in throughput in a substrate processing apparatus can thereby be achieved and increase in the ground-contacting area of the device as a whole can be prevented.
