  • Patent number: 7807024
    Abstract: A system and method for transferring a continuously advancing paper web from a dryer to a reel section is provided. The system includes a first fabric defining a first moving conveyor. The first fabric may be a permeable fabric, which is positioned downstream from the dryer. A second fabric, which may also be permeable and defines a second moving conveyor, is also included. The first moving conveyor overlaps the second moving conveyor for a predetermined distance, and the first and second moving conveyors are configured to receive the paper web between the conveyors. A vacuum device is rotatably disposed against the first moving conveyor, and the dryer and the vacuum device are disposed relative to each other to form an open draw. The vacuum device is configured to produce a vacuum to attract the web to the first fabric for transferring the advancing web into the predetermined distance where the first and second conveyors overlap.

  • Patent number: 6372091
    Abstract: A method and apparatus for beginning the formation of a paper web on a traveling forming wire, or between a pair of converging forming wires, includes a headbox on a papermaking machine for projecting a stock stream onto the forming wire, or between the forming wires over the porous face surface of a forming shoe. The forming wire or wires are looped to travel in a continuous path, and within at least one of the looped forming wires is the forming shoe, which is porous by way of grooves or openings over at least a portion of its face surface. The grooves are in the surface of the forming shoe which engages the inner surface of the looped forming wire to define a portion of the path of travel of the forming wire adjacent the headbox from which the stock stream is projected onto, or between, the forming wire(s). The grooves extend in the surface facing the forming wire from a point downstream of the leading edge in the nose portion of the face surface of forming shoe in the direction of forming wire travel.

  • Patent number: 6306258
    Abstract: A pressurized box is positioned opposite a vacuum box. The pressurized box has a leading cross machine direction baffle with a ceramic shoe which engages a forming fabric, and a trailing cross machine direction baffle of similar construction. Two end deckles complete the pressurized box. The leading cross machine direction baffle presses against a resilient seal which causes a web contained between upper and lower forming fabrics to wrap about the baffle shoe a few degrees forming an effective end seal which does not allow air to bypass the baffle. The trailing cross machine direction baffle is positioned over a vacuum box which prevents air from leaking around the trailing baffle. A vacuum box draws air through the forming fabrics and the web, from the pressurized box increasing the total pressure gradient across the web to 20 to 30 psi or more. The pressure box and opposed vacuum box form an air press. The pressure box is positioned and held against the forming fabrics by opposing air tubes.

  • Patent number: 6143135
    Abstract: An air press for noncompressively dewatering a wet web to consistency levels not previously thought possible at industrially useful speeds without thermal dewatering. The air press has an air plenum and a vacuum collection device, each on opposite sides of two support fabrics that sandwich the paper web. There are cross machine sealing blade(s) that impinge upon the support fabrics and is opposed on the other side of the support fabrics by a sealing member formed of deformable material. The air plenum and vacuum collection device are movable relative to one another so that the sealing blade and deformable sealing member form a seal in the operating position of the air press.

  • Patent number: 6099691
    Abstract: A method and apparatus for cleaning the forming fabric used on a papermaking machine includes a chamber surrounding a span of the forming fabric on either side thereof. A source of sub-atmospheric air pressure is connected to the chamber for removing water mist surrounding the fabric. Mounted within the chamber is a pair of high pressure-low volume water impingement showers in substantially opposed array for directing jets of relatively high pressure water against the forming fabric as the forming fabric passes through the chamber via slots on either end thereof. In a preferred embodiment, downstream of the pair of high pressure needle showers is a second shower apparatus comprising a relatively low pressure-high volume flooding water shower to direct a water spray against the inner side of the looped forming fabric to flood the interstices of the forming fabric with water to wash out pulp fibers therefrom.

  • Patent number: 5861090
    Abstract: Disclosed are methods for electrochemically remediating soil, clay or other media contaminated with organic pollutants using Fenton's Reagent. In the methods, anodes and cathodes are provided in wells formed in the contaminated medium. Anolyte and catholyte solutions are circulated to deliver iron ions to anodes and to deliver peroxide ions to cathodes in the medium. A potential difference is applied across the medium to cause the peroxide ions and iron ions to migrate toward each other and through the medium. The organic contaminants are destroyed in the medium in reactions with the peroxide ions and iron ions. The physicochemical condition of the electrolyte(s) is monitored and adjusted as necessary to control pH and to permit recycling of the electrolyte to the electrodes. Alternatively, peroxide ion can be generated in situ using an air depolarized cathode.

  • Patent number: 5846393
    Abstract: An integrated electrochemical soil remediation method and apparatus for treating contaminated soils, especially those contaminated with mixtures of nonvolatile organic contaminants, ionic contaminants and volatile organic compounds are disclosed. Remediation may be achieved by electrochemically enhancing biodigestion of organic contaminants (using microorganisms present in or added to soil), electrochemically removing ionic contaminants and electrochemically removing volatilized organic contaminants by applying a vacuum over the soil being treated, as dictated by the nature of contamination. Physicochemical conditions of the electrolyte and the soil are managed by monitoring and adjusting the electrolyte. Nutritional needs of microorganisms for biodigestion are adjusted as necessary through the electrolyte.

  • Patent number: 5681445
    Abstract: A bipolar electrode useful in bipolar cell stack electrochemical cells where one of the electrode surfaces is patterned with active and relatively inactive areas where the surface area ratio of the active areas of the electrode surface to the total electrode surface is between 1:2 and 1:50. The use of a grid-like pattern of electrocatalytic material over a conductive substrate is preferred. The electrodes can be used for certain redox reactions to favor particular reaction products.
