  • Publication number: 20190127619
    Abstract: A polymer composition for use in the removal and recovery of oil slicks or spills floating on the surfaces of bodies or water or present on land, such as beaches comprising a foam of a blend of polyethylene and an ethylene-alkyl acrylate copolymer and a process for using such foams in the selective removal of oil from fresh water or salt water and the recovery of the absorbed oils from the foams is disclosed. The polymer composition is also for use in other applications in which absorption of liquids is desired.

  • Patent number: 7706015
    Abstract: Methods and apparatus are provided for processing a print job including a plurality of raster image processed pages. A tab page is created that includes a tab image located at a predetermined position in the tab page, the predetermined position associated with a tab position on tab stock. The tab page is raster image processed, and the rasterized tab page is inserted at a selected position in the print job. The tab image is detected on the rasterized tab page at the predetermined location, and then the rasterized tab image is positioned at the associated tab position.

  • Patent number: 7097369
    Abstract: Method and apparatus for inserting tabs in a print job. A method for inserting tab sheets in a print job is disclosed. First, a position is selected within a document to insert a tab sheet, which document includes a plurality of sheets each with a document defined image space associated therewith. A tab sheet is then created as a rasterized tab sheet image that has a rasterized tab specific image disposed in a predetermined location on the rasterized image. The created tab image is then inserted in the document after rasterizing thereof in the selected position.

  • Patent number: 6449092
    Abstract: Reflective polarizers, which transmit one polarization and reflect the other polarization, have an extended red band edge in the off-axis transmission spectrum to control off axis color (OAC) hue. To control the OAC hue, the red band edge of the off-axis transmission spectrum, or OAC spectrum, is shifted beyond the boundary for red light, or to at least 600 nm. Even more preferably, the OAC spectrum is extended further into the red than any red emission peak of an associated lamp providing light into a system in which the reflective polarizer is used. The concept applies equally well to any type of reflective polarizer, such as multilayer reflective polarizers, cholesteric reflective polarizers, and the like. The resulting reflective polarizers are very useful for many different applications, such as liquid crystal displays.
