  • Patent number: 9715990
    Abstract: Window tiles for electron beam systems are provided. The window tiles can comprise a first surface and a second surface, and one or more features extending from the first surface to the second surface. The one or more features can have a non-uniform or tapered cross-section between the first surface and the second surface. The first surface can be configured to be exposed to vacuum conditions and can be configured to receive electrons accelerated from an electron beam generator. The second surface can be configured to allow electrons to pass through to a foil. The window tiles can improve electron beam processing systems for example by increasing electron throughput, lowering power consumption, reducing heat absorption to the foil, improving and increasing foil life, and potentially allowing for use of smaller and cheaper machines in electron beam processing.

  • Patent number: 4642244
    Abstract: A method and apparatus for coating non-woven and other porous webs and the like with controlled or negligible penetration into the pores by subjecting a coating carried by a surface to electron beam radiation before laminating the web to the surface carrying the coating and with a radiation dose that only partially cures the coating into a soft or tacky state such that the laminating will effect surface spreading adhesion to the web with controlled or substantially no penetration into the pores, and thereafter subjecting the laminated web and partially cured coating to greater electron beam radiation fully to cure the coating.
