An electrically heatable windshield with a hidden bus bar configuration. A border of opaque ceramic material, preferably a lead borosilicate enamel, is bonded to an interior surface of the transparency about its periphery. Opposing electroconductive bus bars, preferably a low frit content silver-containing ceramic material, are bonded to the ceramic material so that the entire inner edge of the bus bar overlays a portion of the ceramic material and is spaced from the inner edge of the border, providing an intermediate portion of the border between the bus bars and transparency surface that is not covered by the bus bars. An electro-conductive coating is applied to the transparency to interconnect the bus bars and covers to the inner surface of the transparency, the bus bars and the intermediate portion of the ceramic material border so that electric current flowing between the bus bars must flow through the portion of the coating that covers the intermediate portion of the border.

Electrically heatable transparency

A novel metal oxide sputtered film comprising bismuth and tin is disclosed on a high transmittance, low emissivity coated glass substrate.

Composite with sputtered films of bismuth/tin oxide

A transparent article for reflecting solar energy comprising a zinc/tin oxide film which exhibits color by interference effects and a reflective metal film preferably comprising chromium is disclosed along with a sputtering method for its production.

Low reflectance, highly saturated colored coating for monolithic glazing

A transparent article for reflecting solar energy comprising a tin/antimony oxide film which exhibits color by interference effects and a reflective metal film preferably comprising chromium is disclosed along with a sputtering method for its production.

A heated transparency is provided with greater reliability by providing dual electrical connections to the bus bar that is at the edge portion remote from the edge at which attachment to the power source are made. Unique features disclosed herein include the provision of leads connected to the remote bus bar that extend along the same side edge of the transparency, and/or the provision of connections to the remote bus bar at locations spaced from the ends of the remote bus bar.

Dual bus bar arrangement for an electrically heatable transparency

A multiple-layer architectural coating comprising titanium oxynitride and a metal film is disclosed, as well as a method for its production.

Method for making colored metal alloy/oxynitride coatings

Colored metal alloy/oxynitride coatings

A transparent article for reflecting solar energy comprising a titanium oxynitride film, a highly infrared reflective metal film and, optionally, a neutral metal alloy film is disclosed along with a sputtering method for its production.

High performance multilayer coatings

A sputtered titanium oxynitride film is disclosed, as well as a low emissivity coated article comprising a titanium oxynitride film in combination with a highly infrared reflective metal film, such as silver.

Sputtered titanium oxynitride films

A transparent article for reflecting solar energy comprising a metal alloy oxide film which exhibits color and a low reflectance metal alloy film is disclosed along with a sputtering method for its production.

Low reflectance bronze coating

A novel metal oxide sputtered film comprising bismuth and tin is disclosed, as well as a method for sputtering such a film and a low emissivity coated article comprising such a film.

Sputtered films of bismuth/tin oxide

A method for making an optically clear, colorless, transparent, electrically conductive coating by vacuum deposition is disclosed. The method involves depositing a first layer of titanium suboxide, a second layer of silver or gold, and a third layer of titanium suboxide, and treating the coating with an oil, wax, or other organic material before exposure to an ordinary atmosphere of air in order to control the rate of subsequent oxidation of the titanium suboxide. The coating deposited on a rigid transparent substrate such as glass or plastic, or on a flexible transparent plastic substrate subsequently laminated to a rigid transparent substrate, is useful for electrically heating windows.

Transparent, colorless, electrically conductive coating

Transparent, electroconductive articles produced by cathode sputtering on refractory substrates, a metal from the group of elements having an atomic number from 48 to 51 and mixtures thereof, and preferably a controlled proportion of tin to indium, in a low pressure atmosphere containing a controlled amount of oxygen at a controlled substrate temperature within a temperature range of 400.degree. F. to a temperature at which the substrate becomes distorted or detrimentally affected, usually at or above 600.degree. F.

Sputter coating of glass with an oxide of a metal having an atomic

An optically clear, electrically conductive, transparent coating on a substrate and a method of coating are disclosed. The coating comprises a first transparent layer deposited as TiO.sub.x on the substrate, where x preferably has a value within the range of 1.3 to 1.7, a layer of silver or gold deposited on the first layer, and a third transparent layer deposited as TiO.sub.x on the second layer, where x preferably has a value within the range of 1.3 to 1.7. The coating is deposited under vacuum in a partial pressure of oxygen on a rigid transparent substrate such as glass or a flexible plastic substrate and the resultant coated substrate used in electrically heated windows.
