20150259854 | WHITEWATER RECOVERY PROCESS - Whitewater recovery processes, and associated systems and components, are generally described. Certain embodiments relate to whitewater recovery processes in which ion exchange is used to remove dissolved ions from the whitewater, which can reduce the degree to which chemical additives are used in the process. In certain embodiments, flocculation and/or filter components can be employed to aid in the removal of suspended solids from the whitewater. | 09-17-2015 |
20150075928 | SYSTEMS AND METHODS FOR PROVIDING DOCTOR BLADE HOLDERS WITH VIBRATION MITIGATION - A self-compensating tube assembly is disclosed for use in a doctor blade holder. The self-compensating tube assembly includes a tube including a membrane that encloses a liquid with a substantially invariable bulk modulus of elasticity, density and viscosity; and chatter responsive for providing any of monitoring means of blade chatter through pressure, damping of blade chatter, and minimizing blade chatter. | 03-19-2015 |
20150075742 | SYSTEMS AND METHODS FOR DOCTOR BLADE LOAD AND VIBRATION MEASUREMENT AS WELL AS BLADE VIBRATION MITIGATION - A doctor blade cartridge for use in a doctor blade holder is disclosed. The doctor blade cartridge is for receiving a doctor blade, and includes at least one blade supporting member, wherein the blade supporting member is sufficiently stiff to support the doctor blade and includes load indication means for providing a signal indicative of at least one of blade supporting member strain and blade supporting member deflection. | 03-19-2015 |

20120260452 | Systems and Methods for Cleaning and Conditioning a Moving Surface Using Cleaning Apparatus with Plate Elements for Mounting to Doctor Blade Holders - A cleaning apparatus is disclosed for processing a moving surface. The cleaning apparatus includes at least one pad that is coupled to a support shoe. The support shoe is attached to a first end of a plate element, and the plate element includes a second end that is adapted to be received by a doctor blade holder. | 10-18-2012 |
20120167330 | DOCTOR BLADE HOLDER - A doctor blade holder system is disclosed that includes a doctor blade holder that includes a doctor blade receiving region for receiving a doctor blade, and an actuation system for causing the doctor blade receiving region to be selectively moved toward or away from a roll surface by rotating the doctor blade holder about a first axis, wherein the doctor blade holder system is generally circular shaped in cross-sectional area and wherein the first axis is generally centrally locate with the generally circular cross-sectional area. | 07-05-2012 |
20110026993 | POSITIONABLE DOCTOR BLADE HOLDERS INCLUDING AT LEAST ONE INTERNAL PLENUM - A doctor blade holder is disclosed that includes a first member, a second member position adjustment elements, and fluid assisted cleaning elements. The first member includes an elongated edge that is adapted for receiving a doctor blade, and the second member is movably coupled to the first member. The second member is secured to a doctor back. The position adjustment elements are for adjusting the relative position of the first member and the second member. The fluid assisted cleaning elements are for providing pressurized fluid to an area near an elongated edge of the doctor blade. The fluid assisted cleaning elements include at least one plenum within the first member. | 02-03-2011 |
20100218909 | Systems and Methods for Cleaning and Conditioning a Moving Surface Using Cleaning Apparatus with Plate Elements for Mounting to Doctor Blade Holders - A cleaning apparatus is disclosed for processing a moving surface. The cleaning apparatus includes at least one pad that is coupled to a support shoe. The support shoe is attached to a first end of a plate element, and the plate element includes a second end that is adapted to be received by a doctor blade holder. | 09-02-2010 |
