US4349610: Method for Waterproofing Paper
ABSTRACT
A method for improving the water repellency of a naturally porous, moisture-containing
paper web by treating the web with a coating composition containing, as its active coating
ingredient, an alkyl alkoxysiloxane, which reacts with the moisture contained in the paper
web to produce a polymer and an alcohol as a by-product. The polymer substantially
improves the water repellency of the paper web, while the web substantially retains the
porosity and the strength characteristics it had in the untreated state.
US4856895: Method and Apparatus for Headbox Jet Velocity Measurement
ABSTRACT
The velocity of a liquid jet, such as the headbox jet of a paper making machine, is
measured by cross-correlation of a.c. signal components produced by a pair of light beams
received by a pair of photodiodes. The light is supplied by a single source, an
incandescent lamp, and is guided by a pair of bifurcated fiber optics mounted above the
jet and spaced apart in the flow direction. The a.c. components are filtered to remove
flow frequencies, amplified and then analyzed in a spectrum analyzer.
