Retarding Or Shielding Of Treatment Patents (Class 34/307)
  • Patent number: 8601715
    Abstract: Machines and methods for curing ultraviolet (UV)-curable coating materials. In one embodiment, the machine includes a UV radiation source having one or more lamps partially enclosed within a shroud of a curing head. The machine may further include a supplemental energy source located outside of the shroud. The supplemental energy source may illuminate an uncured area of the floor coating material that is beyond the curing head. In some embodiments, the supplemental energy source may reduce or prevent the partial curing of the coating material outside of the curing head resulting from stray UV energy.

  • 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.

  • 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.

  • Patent number: 6647640
    Abstract: A drying station for drying printed sheets transported by a transport belt includes an irradiation device for irradiating the printed sheets, a deflection section located in vicinity of the irradiation device for guiding the transport belt away from the irradiation device, and a shielding device disposed between the transport belt and the irradiation device for shielding the transport belt against radiation from the irradiation device while the sheets are exposed to the radiation. A printing machine including the drying station and a method for drying printed sheets are also provided.

  • Patent number: 6493960
    Abstract: An apparatus for drying the air inside of hermetically sealed electronic devices. The apparatus includes a desiccant part and an activation piece that is attached to the desiccant part. The desiccant part and activation piece are attached together and then covered, except for the portions where the two pieces are attached, with a polymer that has a low moisture vapor transmission rate, such as parylene. The apparatus may be added into an electronic device during assembly. The desiccant, or drying agent, is not activated, by removal of the activation piece, until prior to closure of the hermetically sealed electronic device.

  • Patent number: 6470594
    Abstract: A highly moisture-sensitive element and method of making such element includes an encapsulation enclosure encapsulating all of the highly moisture-sensitive electronic devices on a substrate and a sealing material positioned between the substrate and the encapsulation enclosure to form a complete seal between the substrate and the encapsulation enclosure around each highly moisture-sensitive electronic device or around groups of highly moisture-sensitive electronic devices, wherein the substrate or encapsulation enclosure, or both, contain vent holes and vent hole seal material or wherein the seal material contains gaps prior to spacing the substrate and the encapsulation enclosure within a predetermined range and the gaps are filled in by spreading the sealing material.

  • Patent number: 5689899
    Abstract: In order to produce an optimally smooth paint surface in automobiles, the heating phase of the drying process is interrupted when an object temperature of about C. is reached. This object temperature is then held for at least two and at most three and a half minutes. Then the heating phase is continued until the holding temperature is reached.

  • Patent number: 5667641
    Abstract: The invention overcomes the problem of paper edge overdrying during the paper drying process on paper machine drying cylinders. It comprises applying a thin ceramic coating onto the circumferential exterior surface of the cylinder near the cylinder edges, thereby forming a thermal barrier coating which decreases paper drying rate at said edges and reduces or eliminates paper edge overdrying.

  • Patent number: 5488785
    Abstract: The kiln system for drying lumber to a predetermined moisture content according to the present invention includes a kiln chamber for enclosing a charge of green lumber consisting of at least one rectangular solid stack of lumber, a fan for circulating air through the kiln chamber and through the lumber in the kiln chamber to dry the lumber and a relatively lightweight covering overlying and substantially blanketing an upper row of the rectangular solid stacks of lumber. The relatively lightweight covering limits direct contact of the circulating air with the upper row of lumber and prevents excessive drying, warping or cracking of the upper row of lumber. Further, the covering is relatively thin such that the volume of lumber enclosed in the kiln chamber is maximized. The covering is preferably comprised of a substantially rigid material, such as a wooden or a metal sheet.
