Abstract: A drying system and a drying method for a cleaning solution on a mask are disclosed. The drying system includes: a drying chamber having a first side wall and a second side wall arranged opposite to the first side wall; a plurality of first air knives on the first side wall and the second side wall for air-drying a cleaned mask; and a separation device for allowing a mask strip and a supporting and shielding strip to move away from each other at a spatial intersection region to increase a spacing between the mask strip and the supporting and shielding strip at the spatial intersection region, when the plurality of first air knives are air-drying the cleaned mask.
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.
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.

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.
