Patent number: 12000033Abstract: In a method of manufacturing a one-dimensionally varying optical filter, a substrate is coated to form a stack of layers of two or more different types. The coating may, for example, employ sputtering, electron-beam evaporation, or thermal evaporation.

In some approaches, the shadow mask is periodic with a mask period defined along the direction of reciprocation, and the generated reciprocation has a stroke equal to or greater than the mask period along the direction of reciprocation. The substrate and the shadow mask may also be rotated together as a unit during the coating.

Patent number: 8563097Abstract: Certain example embodiments relate to a burner for use in combustion deposition depositing a coating on a substrate. An infrared (IR) burner generates radiant energy in an area between the burner and the substrate. A delivery device (1) provides a stream comprising a substantially vaporized precursor and a carrier gas from a location remote from the radiant energy generated by the IR burner, and (2) causes the stream to flow between the substrate and the IR burner. The stream is substantially laminar when exiting the delivery device. The radiant energy is sufficient to cause the precursor in the stream to be combusted and to heat the substrate to allow at least a portion of the combusted precursor to form the coating, directly or indirectly, on the substrate. The burners of certain example embodiments may be used, for example, to combustion deposition deposit metal oxide coatings onto glass substrates.Type: GrantFiled: November 10, 2009Date of Patent: October 22, 2013Assignee: Guardian Industries Corp.Inventor: David D.

Patent number: 8518475Abstract: In certain example embodiments, a coated article includes respective layers including hydrogenated diamond-like carbon (DLC) and zirconium nitride before heat treatment (HT). During HT, the hydrogenated DLC acts as a fuel which upon combustion with oxygen produces carbon dioxide and/or water. The high temperature developed during this combustion heats the zirconium nitride to a temperature(s) well above the heat treating temperature, thereby causing the zirconium nitride to be transformed into a new post-HT layer including zirconium oxide that is very scratch resistant and durable.Type: GrantFiled: September 20, 2012Date of Patent: August 27, 2013Assignee: Guardian Industries Corp.Inventor: Vijayen S.

Patent number: 8440256Abstract: Certain example embodiments of this invention relate to a method of forming a coating on a glass substrate using combustion deposition. A glass substrate having at least one surface to be coated is provided. A reagent is selected. A precursor to be combusted with the reagent is introduced. Using at least one infrared burner, at least a portion of the reagent and the precursor are combusted to form a combusted material, with the combusted material including non-vaporized material. The glass substrate is provided in an area so that the glass substrate is heated sufficiently to allow the combusted material to form the coating, directly or indirectly, on the glass substrate. The coating may be substantially uniform. In certain example embodiments, a silicon oxide coating may be deposited, which increases visible transmission of the glass substrate by at least about 1.7%.Type: GrantFiled: December 17, 2007Date of Patent: May 14, 2013Assignee: Guardian Industries Corp.Inventors: Mark A.

Patent number: 8435725Abstract: A method for interlaminating a transparent embossed hologram, the transparent embossed hologram comprising a support having two sides, at least one of the two sides either itself being embossed or having a layer thereon which is embossed and a layer of a HRI-material contiguous with the embossed side or embossed layer, comprising the steps of: a) conditioning the outermost surface of the layer of inorganic HRI-material with at least one organic liquid; b) drying the outermost surface of the layer of the inorganic HRI-material thereby providing a conditioned outermost surface of the layer of inorganic HRI-material; c) applying an adhesive layer to the conditioned outermost surface; and d) laminating the outermost surface of inorganic HRI-material to an optionally transparent film, wherein the at least one organic liquid is selected from the group consisting of ketones, ethers, heterocyclic ethers, lactams, amides, halo-aliphatic compounds, nitriles and esters; wherein at least one of the support and the film iType: GrantFiled: September 19, 2008Date of Patent: May 7, 2013Assignee: Agfa-Gevaert NVInventor: Ingrid Geuens

Patent number: 8414970Abstract: Certain example embodiments relate to a method of forming a coating on a glass substrate using combustion deposition. A glass substrate having at least one surface to be coated is provided. An organosiloxane inclusive precursor having a ring- or cage-like structure to be combusted is introduced. Using at least one flame, at least a portion of the precursor is combusted to form a combusted material, the combusted material including non-vaporized material. The glass substrate is provided in an area so that the glass substrate is heated sufficiently to allow the combusted material to form the coating, directly or indirectly, on the glass substrate. In certain example embodiments, the precursor is a cyclic siloxane based and/or polyhedral silsesquioxane (POSS) based precursor, which advantageously may affect the coating's transmission and/or reflection properties compared to conventionally used silicon precursors.Type: GrantFiled: February 15, 2008Date of Patent: April 9, 2013Assignee: Guardian Industries Corp.Inventor: Michael P.

Patent number: 8376839Abstract: A gaming machine includes a cabinet frame, a display, and an emotive lighting area. The cabinet frame has a cabinet surface visible to and facing a player position in front of the gaming machine. The display is mounted to the cabinet frame and is configured to display a randomly selected outcome from a wagering game. The emotive lighting area is integrated with the cabinet frame on the cabinet surface, proximate the display, and is separate from the display. The emotive lighting area includes a light source and a reflective surface, each of the light source and the reflective surface being concealed within the cabinet frame such that they are not viewable from the player position, the reflective surface configured to receive light directly from the light source and to reflect the light to a viewable area.Type: GrantFiled: October 19, 2009Date of Patent: February 19, 2013Assignee: WMS Gaming Inc.Inventors: Paul M.
