Abstract: The feed of a sheet of biscuit dough via gauge rollers to cutting apparatus is automatically adjusted to compensate for variations in the thickness of the sheet emerging from the gauge rollers, by measuring the power consumed by or the torque applied to an electrical drive unit driving the gauge rollers, producing an electrical signal proportional to the measured power or torque, and utilizing the signal to adjust the feed of the sheet and correct over- or under-feed to the gauge rollers.

Abstract: Degradation-resistant polyolefin articles, such as fibers, films, sheets and the like, are prepared from polymeric compositions containing a stabilizing system comprising a hindered amine and a nickel phosphonate which have been overcoated with a finish comprising an ethoxylated lubricant and a phosphate ester. In a preferred embodiment, polypropylene textile materials having improved thermal stability are provided compositions containing a stabilizing system comprising a hindered amine and a nickel phosphonate which have been overcoated with a finish composition comprising an ethoxylated lubricant and a phosphate ester in an amount sufficient to impart antistatic properties to said composition and increase the thermal stability of said polypropylene textile materials.
