Patent number: 6322862Abstract: An object containing pressed flowers sealed therein which is composed of a base layer, an intermediate layer of molten resin in which is sealed a pressed flower, and a surface layer of transparent film, with these three layers integrally laminated on top of the other, characterized in that the intermediate layer is formed by pressing with heating under reduced pressure from a meltable porous plastic film such that the molten plastic adheres closely to the pressed flower to seal it and also fixes the pressed flower to both the base layer and the surface layer of transparent film. It retains the natural color of the pressed flower for a long period of time without deterioration by air and moisture.Type: GrantFiled: April 17, 2000Date of Patent: November 27, 2001Assignee: Doppel Co., Ltd.Inventor: Tsuyoshi Sakai

Publication number: 20010031353Abstract: This invention relates to an adhesive article which provides air egress. Air egress is provided by supplying a route, such as areas of no initial adhesion for the air to flow out from under the construction. The invention relates to an adhesive article comprising a facestock having a front surface and a back surface, a continuous layer of adhesive having an upper surface and a lower surface wherein the upper surface of the adhesive layer is adhered to the back surface of the facestock, and a plurality of spaced-apart non-adhesive material which is in contact with the lower surface of the adhesive layer wherein the lower surface of the adhesive layer has a Sheffield roughness of at least about 10 and the adhesive article provides air egress. The invention also relates to methods of preparing the adhesive articles. These articles have usefulness as industrial graphics images, as well as decorative coverings, etc. The articles provide air egress and optionally repositionability and slideability.Type: ApplicationFiled: December 21, 2000Publication date: October 18, 2001Inventor: Michael Hannington

Patent number: 6294233Abstract: Transparent edge sealed window films substantially minimize (if not eliminate entirely) degradative effects on the window film, particularly solar-reflecting metals and/or oxides associated with multilayer window films, caused by ambient conditions (e.g., commercial window cleaners, salt and the like). The edges of window films are preferably sealed by a liquid solvated polymeric material which, upon curing, provides a solid transparent seal which significantly minimizes the degradative effects of the ambient environment. Most preferably, the window film whose edges are sealed will include a transparent thermoplastic (e.g., a polyester) film layer and a solar-reflecting metal and/or oxide applied onto a surface of the film layer. The sealant for such a preferred window film will be a polyester-type sealant which has silane end-group functionality and substantially no free isocyanate groups.Type: GrantFiled: March 23, 1999Date of Patent: September 25, 2001Assignee: C P Films, Inc.Inventors: Steven A. Barth, Steven L. Debusk

Patent number: 6251516Abstract: A method of microdissection which involves forming an image field of cells of the tissue sample utilizing a microscope, identifying at least one zone of cells of interest from the image field of cells which at least one zone of cells of interest includes different types of cells than adjacent zones of cells, and extracting the at least one zone of cells of interest from the tissue sample. The extraction is achieved by contacting the tissue sample with a transfer surface that can be selectively activated so that regions thereof adhere to the zone of cells of interest to be extracted. The transfer surface includes a selectively activatable adhesive layer which provides, for example, chemical or electrostatic adherence to the selected regions of the tissue sample. After the transfer surface is activated, the transfer surface and tissue sample are separated.Type: GrantFiled: February 4, 1998Date of Patent: June 26, 2001Assignee: The United States of America as represented by the Department of Health and Human ServicesInventors: Robert F.
