Shielding By Selective Application Of Gas Or Vapor Flow Patents (Class 34/309)
  • Coating film drying method, coating film forming method, and coating film forming apparatus
    Patent number: 6960372
    Abstract: The present invention uniformly dries, in a clean room in which down flow is constituted, a coated film formed on a surface of a substrate held in a state that the coated surface faces down. In a coating apparatus including an absorption board holding a substrate in a state that its surface to be coated looks down, and a coating mechanism that coats with coating liquid the surface to be coated of the substrate held by this absorption board, there is provided an air current generating apparatus which supplies clean gas toward the surface to be coated.

  • Bag for home dry cleaning process
    Patent number: 6658760
    Abstract: A flexible container in the form of a bag is described for use in a non-immersion dry cleaning process. Bag walls that are appropriately stiff and slick are preferred (preferred Kawabata Evaluation System stiffness and surface friction values are given), as are bag designs that are inherently three-dimensional and self-supporting. A preferred embodiment is a tetrahedral bag having a slick polymeric coating on the interior surface.

  • Cryogenic/phase change cooling for rapid thermal process systems
    Patent number: 6105274
    Abstract: A process for treating a workpiece. The workpiece is cooled by directing toward the workpiece a material that includes a gas and particles of a material that undergoes a phase change when applied to the workpiece. The gas and the particle material are non-reactive with the workpiece during the cooling.

  • Method and apparatus for renewing a roof system
    Patent number: 5950326
    Abstract: An apparatus for renewing a roof system of a building includes a blower having an intake port and an exhaust port in gaseous communication with the interior of the roof system to reduce the moisture content of the roof system. A method of renewing the roof system includes the steps of blowing air into the roof system until the roof system is dried to a predetermined level and applying a coating or second covering to the dried roof system.
