Abstract: A degrading agent composition for use in manufacturing a tissue product generally includes a degrading agent, a degradation inhibiting carrier, and a non-ionic surfactant. The non-ionic surfactant stabilizes the viscosity of the composition as a function of time. The degrading agent composition can be used in combination with a temporary wet strength agent to produce a tissue product exhibiting high initial wet tensile strength and desirable decay properties. Processes for forming the tissue product and pumpable fluids containing the degrading agent composition are also disclosed.

Abstract: Systems and methods are disclosed for improving digital feed-forward data recovery of high speed data from a received data stream in a data transceiver or receiver where the receiver clock is asynchronous to the transmitter clock used to transmit the received data stream. In one example, the received data stream is oversampled using N evenly-spaced multi-phase clocks. The oversampled data are packed into a data block. Data transition edges of the oversampled data in the data blocks with respect to multi-phase clocks are tracked. The tracked data transition edges are used to determine the length of a decision window and to further divide the oversampled data into groups of bits that are hypothesized to be samples of the same received data symbol. Bit mapping is performed on the decision window to recover the received data symbol. By tracking the movement of data transition edges, the technique enhances data recovery capability.

Abstract: Compositions comprising a blend of two or more paper strengthening agents have improved stability compared with previously known paper strengthening agents. One component is a polymeric paper strengthening agent, preferably a wet strengthening agent. The other component is a stabilized polyacrylamide prepared by (1) reacting a first portion of glyoxal with a polyacrylamide having pendant amide groups to form a first reaction mixture comprising polyacrylamide; (2) adding an acid to the first reaction mixture to form a second reaction mixture having a reduced pH and comprising the polyacrylamide; and (3) adding a second portion of glyoxal to the second reaction mixture to form the stabilized polyacrylamide. If desired, an aldehyde scavenger can be included in one or more of step (1), step (2), step (3), or the stabilized polyacrylamide. Such compositions can be used to enhance the strength of paper, particularly the wet strength of paper.
