Patent number: 7781024Abstract: The invention relates to a method for producing ceramic layers by spraying. A cold gas spraying method is used to produce polymer ceramics from pre-ceramic polymers. According to said method, a cold gas stream, to which particles of the pre-ceramic polymers are added via a conduit, is generated by a spray gun. The energy for creating a layer on a substrate is produced by injecting a powerful kinetic energy into the cold gas stream, thus preventing or significantly restricting the thermal heating of the cold gas stream. This permits the heat-sensitive pre-ceramic polymers to be spray-applied as a coating on a substrate using a cold gas spraying method. Polymer ceramics can thus be used in an economic method for the rapid production of layers with a relatively large thickness. The invention allows for example armoured layers, thermal protection layers and other functional layers to be produced.Type: GrantFiled: June 23, 2006Date of Patent: August 24, 2010Assignee: Siemens AktiengesellschaftInventors: Ursus Krüger, Raymond Ullrich

Publication number: 20090104367Abstract: A method is disclosed of pretreatment and/or precoating of nonabsorbent substrates and/or nonabsorbent support materials, in particular of plastics, metals or glass, for ink printing or inkjet printing with water-based ink with a pretreatment solution and/or coating. The method includes applying at least one initiator which physically or chemically induces a sufficiently rapid reduction of the flowability of the ink to the substrate and/or support material, giving a defined ink distribution.Type: ApplicationFiled: August 16, 2007Publication date: April 23, 2009Applicant: TRITRON GMBH & CO.KGInventor: Jens Simon

Publication number: 20090104370Abstract: A micro-structural film manufacturing process operating on a principle of static absorption by having multiple optical particles adhered to an adhesive layer containing adhesion on a surface of a base material, followed with solidification and static removing processes for the optical particles to form a film of micro-lens diffusion layer to deliver scattering results when light is permeated for achieving the purpose of having uniform luminance while reducing production cost and allowing control the surface of the base material to develop a micro-structural film under different diffusion conditions.Type: ApplicationFiled: October 17, 2007Publication date: April 23, 2009Applicant: NATIONAL APPLIED RESEARCH LABORATORIES, NATIONAL CENTER FOR HIGH-PERFORMANCEInventors: CHI-FENG LIN, PO-HUA YANG

Patent number: 7517556Abstract: The present invention relates to a method of manufacturing a consumer scrubbing wipe article. The method comprises providing a nonwoven substrate having a dry basis weight of less than about 300 g/m2 where the nonwoven substrate defining first and second opposing surfaces, providing an abrasive resin-based matrix, printing the matrix onto the first surface of the nonwoven substrate, and coalescing the matrix to create a texture layer that provides a scrubbyness attribute. The printed matrix covers less than an entirety of the first surface, and the texture layer is created without crosslinking of the matrix resin. The texture layer extends at least 50 microns outwardly beyond the first surface upon coalescing.Type: GrantFiled: August 11, 2005Date of Patent: April 14, 2009Assignee: 3M Innovative Properties CompanyInventors: Mitchell T. Johnson, Timothy J. Lindquist

Patent number: 7510743Abstract: A process for manufacturing a device adapted for exposure to high temperatures. A support structure for retaining a ceramic insulating material on a substrate is formed by the deposition of a support structure material through a patterned masking material. The support structure can define cells into which the ceramic insulating material is deposited following removal of the masking material. The support structure may be a composite metal-ceramic material having either discreet layers or a graded composition deposited by an electro-deposition process followed by a heat treatment to form a solid state diffusion bond with the substrate. The ceramic filler material may be deposited by the electrophoretic deposition of ceramic particles coated with a bonding material that is subsequently heated to oxidize and to bond the particles together. The support structure may be formed with inclined walls in order to improve its resistance to foreign object impact damage.Type: GrantFiled: December 8, 2004Date of Patent: March 31, 2009Assignee: Siemens Energy, Inc.Inventor: Ramesh Subramanian
