  • Patent number: 10241452
    Abstract: An image forming apparatus includes an image forming unit, a fixing device, output tray, a toner container, a cooling fan, an outer wall, and a downstream branch duct. The toner container is located under the tray and beside the fixing device, and accommodates a toner. The cooling fan is located between the toner container and the fixing device. The outer wall is provided under the output tray so as to cover an upper portion of the toner container, to form an upstream duct that allows air to flow therethrough over the toner container toward the cooling fan. The downstream branch duct conducts the air discharged from the cooling fan to the fixing device, and to a transport route of the recording sheet from the fixing device to the output tray. The outer wall includes a plurality of intake holes for sucking air into the upstream duct.

  • Patent number: 7140828
    Abstract: Objects such as pieces of mail are stacked without significant contact therewith by producing laminar air flow over a surface which defines or parallels a desired movement path for the objects. The objects are placed and form a barrier between the laminar air flow and ambient air and movement such as turning an edge of the object to prevent impact on other objects and regulation of direction velocity an kinetic energy of the motion of the objects is regulated by the Coanda effect of the laminar flow. The object thus provides an acoustic barrier to reduce generation and propagation of noise by the high pressure air used to create the laminar flow. An air amplifier reduces the volume of high pressure air required to provide control of object motion.

  • Patent number: 6846151
    Abstract: Objects such as pieces of mail are stacked without making significant mechanical contact with the objects by an apparatus producing a laminar flow of air over a surface which defines or parallels the desired path of movement for the objects. The objects are placed to form a barrier between the laminar air flow and ambient air so that movement, such as turning an edge of the object to prevent impact on other objects and regulation of direction velocity and kinetic energy of the motion of the objects, may be guided by the Coanda effect of the laminar flow of air. The placement of the objects thus provides an acoustic barrier to reduce the generation and propagation of noise by the high pressure air used to create the laminar flow of air. An air amplifier reduces the volume of high pressure air required to control the movement of the objects.

    Abstract: A sheet offset printing method and a sheet offset printing press includes altering flow relationships in an interior of a housing of a sheet delivery of a sheet-fed printing machine to prevent uncontrolled spread of powder in the housing by extracting powder-laden air from the housing and/or feeding air into the housing from outside at a point along a return belt of a sheet conveying device. Air currents are channeled inside the housing by feeding air not laden with powder into the housing and/or leading the air into an air flow path along the return belt downstream of the point with respect to a return belt motion direction to transport the unladen air toward a printing unit by a drag effect of the return belt and/or impeding/blocking a supply of powder-charged air from around a conveyor belt of the sheet-conveyor or a powder-scattering device into a flow path along the return belt.
