  • Patent number: 11980922
    Abstract: Methods for producing a coiled strip of metal matrix composite (MMC) material are disclosed. The methods include a combination of hot rolling and warm rolling processes that reduce the thickness of the input material and increase its ductility. The resulting MMC strip can be coiled, which is useful for high volume coil-to-coil applications.

  • Patent number: 9855200
    Abstract: An oral care composition and method are described in which the composition includes a film or a plurality of film fragments entrained in a carrier. The film or plurality of film fragments comprises a zinc compound and the carrier comprises a polysaccharide and a maleic anhydride copolymer. The composition and methods provide benefits including one or more of increased consumer acceptability, improved solubility of zinc thus permitting the use of lower amounts of zinc compounds and reducing the adverse astringency associated with zinc, decreased adverse reactions brought about by the presence of zinc ions, enhanced aesthetics, improved stability for active or other functional materials, and controlled delivery of active materials such as zinc.

  • Patent number: 5598770
    Abstract: An automated process is provided for controlling process parameters, such as moisture content and grain feed rate, in a grain processing system. Control of process parameters may be provided by an automatic control system which receives signals from input devices, such as moisture sensors, and generates signals to control the parameters. The automatic control system may provide control signals that are feedback, feedforward, or a combination of feedback and feedforward control. Grain processing system components may include a grain conveyor, a wetting system, a steam chest, a flaking mill, a livestock pelletizer, and/or a cooler assembly.

  • Patent number: 4431124
    Abstract: Belt-like traveling guide apparatus has been provided for guiding side edges of metal strip material that is being positively advanced from, for example, an uncoiling station to a second or processing station. Side pairs of idler guide rolls are employed for maintaining the material in a planar relation during its movement, and idler head and tail and upper and lower guide rollers are employed for maintaining one side face of each of a pair of continuous belts in synchronized movement engagement with opposite side edges of the material to thereby protect them and, at the same time, positively and accurately align the material during its forwardly advancing movement between the stations.
