  • Patent number: 8833295
    Abstract: An adhesive masking article for shielding a protected work surface from a coating applied to a surface adjacent the protected work surface includes a backing layer having first and second opposed major surfaces, and at least one edge, an adhesive on at least a portion of at least one of the first and second backing layer opposed major surfaces, and a barrier inducing treatment on at least an edge surface of the masking article to contact the coating when the coating contacts the edge of the backing layer, thereby causing a barrier to form along the edge of the masking article that impedes the migration of the coating past the edge of the masking article beneath the masking article.

  • Patent number: 6827459
    Abstract: In one embodiment, the invention is directed toward an apparatus that includes a first layer and a second layer attached with one another via sets of fastening elements formed on the layers. The fastening elements may comprise hook-like elements that engage one another in an interlocking arrangement to attach the layers, or alternatively, the fastening elements may take any form envisioned by a designer. In any case, the apparatus may also form a light guide that can be illuminated with a light source to transmit light by total internal reflection (TIR).

  • Patent number: 6763556
    Abstract: The invention is a mating film. The mating film comprises a base sheet having a first major surface. A plurality of generally parallel ridges project from the first major surface. The ridges comprise a stem portion attached to the base sheet and generally upright from the base sheet. A head portion of each ridge is spaced from the first major surface and extends generally laterally from the stem portion so as to define a lateral distance. The center of each stem portion of each ridge is spaced from the center of each adjacent ridge stem portion by a distance greater than about 2 times lateral distance defined by the head portion.

  • Patent number: 6740832
    Abstract: A switch apparatus includes a first layer and a second layer attached to one another via sets of fastening elements formed on the layers. The fastening elements may comprise hook-like elements that engage one another in an interlocking arrangement to attach the layers, or alternatively, the fastening elements may take other forms. The fastening elements may include flexible portions that flex when the first layer and second layer are forced together. The apparatus may be used within switch arrays, and can eliminate the need for dome spring elements.

  • Patent number: 6589317
    Abstract: An electrostaticly charged filtration media is provided including a plurality of polymeric structured polymeric film layers having a structured surface defined on at least one face of each structured film layer forming at least in part flow channels. The plurality of structured film layers are configured as a stack with the structured surfaces defining a plurality of ordered inlets open through a face of the stack that are in fluid communication with ordered fluid pathways. Each fluid pathway is defined at least in part by at least one discrete flow channel such that fluid can flow substantially unimpeded from one of the inlets to an outlet opening at another face of the stack. A layer of fluid pathways is defined by two opposing charged film layers at least one of which is a structured film layer. The flow channels have an average height of from 0.1 mm to 5 mm and an average width of from 0.05 mm to 50 mm and an average aspect ratio of from 0.5 to 10.
