  • Patent number: 5149193
    Abstract: An extruder temperature controller for an extruder barrel and a method for controlling the temperature of an extruder barrel, includes a device for determining an actual screw speed and for storing a plurality of screw speeds. Each member of the plurality of stored screw speeds has a corresponding stored temperature reset value. The extruder temperature controller has a device for comparing and selecting that compares the actual screw speed to each of the plurality of stored screw speeds and selects a default screw speed. The default screw speed has a smaller deviation from the actual screw speed than any other member of the compared, stored screw speeds. The controller further includes a device for generating a control output driver signal to a heat exchanger. The control output driver signal is the corresponding stored temperature reset value for the default screw speed.

  • Patent number: 4877538
    Abstract: This invention relates to a new process and group of products that are useful in preventing nylon and wool fibers, including carpeting and upholstery, from being permanently stained. Fibers can be permanently stained by food colors contained in food spilled on the fiber. This new group of sulfomethylated phenol-formaldehyde or naphthol-formaldehyde and anionic surfactant compounds not only block the stain from the fiber but also minimize any yellowing or discoloration of the treated fibers during the application and during the subsequent exposure to sunlight or commonly used lightfastness testing equipment.
