Patent number: 5429850Abstract: An adhesive tape is provided which is obtained starting from a roll of composite material consisting of a first continuous strip or tape of film material and a second continuous strip in a material having low adherence to adhesives, such as a siliconized continuous backing strip, the film material being a high-strength polymeric material film having adhered to one face thereof at least one extremely thin continuous run of adhesive obtained by applying said continuous backing strip onto said tape whereby said adhesive remains on said tape after removal of said continuous backing strip by virtue of the greater adhesion of said adhesive to said tape than to said continuous backing strip, said adhesive tape being useful for splicing continuous webs of thin films.Type: GrantFiled: February 1, 1994Date of Patent: July 4, 1995Assignee: E. I. Du Pont de Nemours and CompanyInventor: Alfons N. Held

Patent number: 5407697Abstract: A method of continuously painting one side of a moving substrate metal strip (1) utilizing a thermosetting polymer based paint composition comprises pre-heating the strip in a pre-heat furnace (2) to a pre-heat temperature above the glass transition temperature of the paint composition, driving a solid block (8) of the paint composition into collision with the strip at a predetermined block speed to cause liquid paint to be melted from the block and applied to the strip at a precisely controlled deposition rate. The deposit, which for thin paint coats is discontinuous, is then spread over the surface of the strip by a pressure roll (14) and emerges therefrom as a smooth coat of wet paint. A bead of liquid paint (17) builds up on the strip on the up stream side of the pressure roll and the block speed may be adjusted in response to the bead size. The emergent strip then travels through a paint curing furnace (5) and a bath (6) to complete the process.Type: GrantFiled: July 7, 1993Date of Patent: April 18, 1995Assignees: John Lysaght Limited, Taubmans Proprietary LimitedInventors: Udo W. Buecher, Trevor J. Horton

Patent number: 5372666Abstract: A method of manufacturing a multilayered circuit board, comprises the steps of: (a) laminating an insulating sheet on a lower layer (2) which reflects a laser light applied through the insulating sheet (4 and 6), said insulating sheet comprising a carrier film (4) and an insulating layer (6) formed on the carrier film; (b) forming via holes (8) in predetermined parts of said insulating sheet by applying a laser light thereto; (c) filling a conductive material (10) in the via holes formed in said insulating sheet; (d) forming a circuit-pattern layer (12) on said insulating layer with the via holes filled with the conductive material; (e) repeating steps (a) to (c) on an uppermost insulating sheet, and repeating steps (a) to (d) until a desired number of circuit-pattern layers are formed below said insulating sheet, in the case where the board has at least two circuit-pattern layers; and (f) firing the layers of the multilayered structure formed in the step (e) at the same time.Type: GrantFiled: April 4, 1994Date of Patent: December 13, 1994Assignee: E. I. Du Pont de Nemours and CompanyInventor: Sadanobu Kawasaki

Patent number: 5356497Abstract: A method for forming a sheet material permeable to gas and not permeable to water includes forming the sheet material by hot pressing two materials together, and discharging static electricity to the sheet material in order to form a number of apertures in the sheet material. The apertures have a size smaller than that of water particles and larger than that of gas particles such that the sheet material is permeable to gas and not permeable to water.Type: GrantFiled: May 5, 1993Date of Patent: October 18, 1994Inventor: Chi S. Lee

Patent number: 5336348Abstract: The present invention provides a method for forming a coherent vermiculite film which can be performed on a continuous basis. An exemplary method comprises the steps of providing a non-flocculated dispersion of delaminated vermiculite platelets, providing a flexible release carrier having a surface operative for retaining thereupon a wet film of said dispersion and further operative for releasing the vermiculite film when dried, applying a wet vermiculite film to the moving carrier, and drying the vermiculite film, whereby the dried film is releasable from the carrier. The flexible release carrier preferably comprises paper having a release agent coating thereon. The invention also provides a flexible carrier-supported releasable vermiculite film, a film made from an vermiculite-aziridine composition, a composition of vermiculite and an aziridine, and a composition of vermiculite and amine resulting from an aziridine.Type: GrantFiled: December 16, 1992Date of Patent: August 9, 1994Assignee: W. R. Grace & Co.-Conn.Inventor: Richard E. Mindler

Patent number: 5328534Abstract: A method of forming a transferable pattern or image of an inorganic film by coating an embossed substrate with an inorganic layer, that may comprise one or more films, over both recessed and raised surface portions, adhesively laminating a transfer substrate to the inorganic layer coating the raised surface portions of the embossed substrate and separating the embossed substrate and the transfer substrate. The adhesive is selected such that the bond between the transfer substrate and the inorganic film on the raised surface portions is greater than the bond between the inorganic layer on the raised surface portions and the embossed substrate.The embossed substrate resulting after removal of the inorganic layer coating the raised surface portions may be modified to include additional inorganic layers over the recessed surface portions by tinning or electroplating methods such that this thickened inorganic layer may also be transferred from the embossed substrate to a transfer substrate as set forth above.Type: GrantFiled: February 22, 1993Date of Patent: July 12, 1994Assignee: Minnesota Mining and Manufacturing CompanyInventors: Clyde D. Calhoun, David C. Koskenmaki
