Publication number: 20170332524Abstract: Methods and devices for shielding electronic equipment within an enclosure are disclosed. One method includes positioning electronic equipment within an interior volume of a shielding enclosure having an opening providing access to the interior volume, the opening surrounded by an enclosure frame. The method further includes closing a door to the shielding enclosure, thereby closing off the opening, and engaging one or more latches to affix the door in a closed position, the door including a shielding curtain positioned across the opening. The method also includes inflating an inflatable member positioned along a perimeter of the door frame, thereby applying a uniform pressure to the shielding curtain toward the enclosure frame to form a seal therebetween.Type: ApplicationFiled: May 1, 2017Publication date: November 16, 2017Inventors: GEORGE ANDERSON, WILLIAM M.

Patent number: 9670373Abstract: The invention relates to a polymer (P) comprising at least one photoinitiator moiety (PI) and at least one dye moiety (DYE), wherein said at least one photoinitiator moiety (PI) and at least one dye moiety (DYE) are covalently linked to said polymer (P). Additionally, the invention relates to said polymer (P) being end-functionalized with optionally substituted acryloyi groups. The fact that both of these moieties are tightly bonded within the polymer, and the cross-linked polymer, means that the opportunities for leaching/migration of these components is reduced or even eliminated. Inks comprising at least one of said polymers are also provided. Methods for the manufacture of the polymers, and for printing are provided.Type: GrantFiled: August 24, 2012Date of Patent: June 6, 2017Assignee: Lambson LimitedInventors: Niels Joergen Madsen, Christian B.
