  • Method and system for color film separation preprocess using electronic object-based choking and spreading procedures including object combining operations
    Patent number: 5438653
    Abstract: A computer system for production of ink separations from an object-based print pre-process apparatus using a page description language. The print pre-process system facilitates creation of object spreads for any combination or configuration of objects on the rendered page. For each object on a rendered page, the computer system 100 makes use of a spread table to determine spread incidences. For each spread incidence, the computer system generates set union, intersection, difference, and edge extraction for spreading, receiving, and obstructing objects to create a simplified graph of contour histories providing a visible portion of the spread object. The visible boundary between the visible spread object and the receiving object is then extracted. The visible boundary is strokeable within a clipped window set to the receiving object. The stroke color and width, set by the spread table, can be knockout print or overprint.

  • Coal-aqueous mixtures
    Patent number: 4358293
    Abstract: Coal-aqueous mixture characterized by having high coal solids concentrations are provided. Selected polyalkyleneoxide nonionic surfactants are employed at low concentrations to disperse coal in an aqueous carrier medium to coal solids levels of 70% by weight, or higher. The selected polyalkyleneoxide nonionic surfactants are characterized by having a high molecular weight and a hydrophilic portion comprised of at least about 100 repeating units of ethylene oxide.
