  • Publication number: 20020124429
    Abstract: In the dryer section of a paper machine, the paper web is pressed against the dryer cylinders by means of an air-permeable endless dryer fabric. A ventilator apparatus extends transversely across the paper machine located outside the pocket above and below the fabric turning rolls. Air from the ventilator is forced into the pocket through the fabric in the nips formed by the fabric and the fabric turning roll. This air dilutes the moisture driven from the sheet by the dryer can. The ventilator apparatus also creates a negative pressure region to exhaust air from the pocket. This exhaust air is used to scour the boundary layer of moisture laden air from the incoming fabric. The two-pass ventilator apparatus has two individual chambers separated by an induction chamber. The primary chamber contains multiple air jet nozzles. The blowing directions of the two longitudinal nozzles may be at different angles with respect to the running direction of the dryer fabric.

  • Patent number: 5081503
    Abstract: Carrier bead pick-off device including a magnet assembly and an enclosure in which the magnet assembly is reciprocated between a first position where carrier beads are picked off the photoreceptor and a second position where the carrier beads are caused to be returned to a developer housing structure. The enclosure in one embodiment of the invention forms part of the developer housing structure. The magnet is retracted such that it follows the contour of the enclosure so that the carrier beads are swept into the developer housing structure.

  • Patent number: 5061969
    Abstract: A hybrid development system for developing composite tri-level xerographic latent images in which conductive magnetic brush (CMB) development system is employed at the first development station and insulative magnetic brush (IMB) development system is used at the second station. In order to preclude spurious fringe field development by the IMB development system at the second development station the conductivity of the IMB developer is in the order of 10.sup.-13 to 10.sup.-15 ohm-cm. Additionally, a scorotron corona charging device located between the two development housings may be used to charge the image developed at the first station to the same potential as the background (white level) thereby eliminating spurious fringe field development by the IMB developer with a conductivity less than 10.sup.-13 ohm-cm at the second development station.

  • Patent number: 5056259
    Abstract: A solar greenhouse includes a peripheral wall structure defining a partially enclosed area having an open side through which plants can be placed inside for admitting light into the greenhouse, and a roof over the wall structure. The roof is removable from over the peripheral wall structure to provide for the easy installation, removal, or rearranging the plants. The inside surfaces of the wall structure and roof are light reflecting to reflect light entering the greenhouse through the open side toward the plants inside the greenhouse. The greenhouse also includes a floor which is a separate component from the peripheral wall structure. The exposed surface of the floor can also be light reflecting. The inclination of the roof relative to the horizontal can be changed to adjust the angle of light reflection of the roof.

  • Patent number: 5038177
    Abstract: Balanced, efficient corona transfer for both the charged area image and the discharged area image of a developed tri-level image is obtained by the provision of a selective pre-transfer charge corona device in combination with a pre-transfer discharge lamp. While improved transfer over prior art devices is obtained using a pre-transfer lamp prior to pre-transfer charging the preferred embodiment of the invention utilizes a pre-transfer lamp before and in coincidence with pre-transfer charging.

  • Patent number: 4868608
    Abstract: Tri-Level Highlight color imaging apparatus and cleaner apparatus therefor. Improved cleaning of a charge retentive surface is accomplished through matching the triboelectric properties of the positive and negative toners and their associated carriers as well as the carrier used in the magnetic brush cleaner apparatus. The carrier in the cleaner upon interaction with the two toners causes them to charge to the same polarity. The carrier used in the cleaner is identical to the one use in the positive developer. The carrier of the negative developer was chosen so that the toner mixed therewith charged negatively in the developer housing.Thus, the combination of toners and carriers is such that one of the toners charges positively against both carriers and the other of the toners charges negatively against one of the carriers and positively against the other.
