  • Patent number: 6168687
    Abstract: Significant improvements in papermaking control can be achieved by employing an array of sensors that are positioned underneath the wire of the machine to measure the conductivity of the aqueous wet stock. The conductivity of the wet stock is directly proportional to the total water weight within the wet stock; consequently, the sensor provides information which can be used to monitor and control the quality of the paper sheet produced. Because CD water weight profile is obtained practically instantaneously, the MD and CD variations are essentially decoupled. Quality improvements to the sheet fabricated will be achieved by providing fast control of the actuators on the machine and by tuning components on the machine to eliminate the sources of variations.

  • Patent number: 6158441
    Abstract: A shower of tobacco particles is admitted into the inlet at the top of and descends by gravity and/or under the action of a driven cell wheel in a generally upright duct. The particles are moisturized prior to admission into the duct or due to contact with droplets of water in the inlet, and are thereupon caused to traverse an orbiting shower of steam, water and/or another conditioning medium in an intermediate portion of their path in the duct. Such treatment entails a swelling and thus increases the volume of the particles. The conditioning medium is discharged via orifices radially outwardly from at least one substantially horizontal conduit which is rotated about its axis and can be provided with external pins or analogous mechanical impellers serving to cause the particles of tobacco to orbit about the conduit prior to descending into the range of a dryer at a level below the intermediate portion of the path, e.g., at the outlet of the duct.

  • Patent number: 6120648
    Abstract: Methods and apparatus for recycling office waste paper and the like of the type having ink and laser print particles coated thereon. The waste paper is simultaneously pulped and ink particles dispersed by kneading the waste paper in the form of a high solids content aqueous mixture or sludge. After the simultaneous pulping and dispersing, no additional dispersion step is needed to form deinked paper stock. The high solids content aqueous mixture or sludge is diluted and forwarded to wet deinking separation devices such as a froth flotation unit or the like. The thus treated pulp is washed and results in the formation of a high quality pulp stock ready for bleaching and/or paper making procedures.
