Abstract: The present application discloses a sizing method for making paper. An alkenyl succinic anhydride (ASA) is added to a papermaking process. An aluminum salt is added in one or more process steps during the papermaking process. Preferably, the aluminum salt is an aluminum salt which can generate free aluminum ion in aqueous solution. The sizing method of the present application enhances the usage efficiency of a sizing agent and the aluminum salt, as well as provides paper having a high moisture content.

Abstract: The present invention provides an automatic control system, method and paper manufacturing machine using such control system for automatically controlling the amount of press section dewatering via the metered application of chemical dewatering agents applied to a paper web in a paper manufacturing process. The control system includes a feedback controller for controlling the amount of chemical dewatering agent applied to a paper web, and a monitoring device for obtaining a measurement of the moisture of the paper web exiting the press section.

Abstract: The present invention includes a system and method for coherent imaging. The system of the present invention includes a light source adapted to provide coherent light to illuminate a sample resulting in optically mixed coherent signals and a detector adapted to receive the optically mixed coherent signals and produce an output signal in response thereto. The optically mixed coherent signals will be a set of sum and difference frequency combinations of the frequencies in the coherent light. A processor is connected to the detector and adapted to ratio a selected two of the optically mixed coherent signals in response to the output signal received by the detector and to generate an image in response to the ratioed optically mixed coherent signals, which can be displayed for a user.

Abstract: A method for improving sizing efficacy, paper machine performance and sheet properties formed during a papermaking process is disclosed. The methodology includes the following steps: (a) applying one or more sizing chemicals to the papermaking process to a point between after the headbox and on or before the first drainage element of a papermaking process.

Abstract: A method of operating a papermaking process containing a press section with at least one press nip is disclosed.
