Abstract: Screen printable, air fireable compositions comprising (1) vanadium glass or a product of silica and vanadium glass, (2) boron silicide and (3), as optional components, boron, noble metal and/or a low melting inorganic binder, wherein the glass contains 5-55 percent vanadium metal content. Electronic devices are made from these compositions. A unique feature of the devices is their sensitivity to voltage as well as temperature. Consequently, the fired compositions are particularly useful wherever switching devices are needed, e.g., as transient suppressors in electronic equipment. A process for making electrical devices by firing subject compositions on substrates in a belt furnace.

Abstract: A current transfer brush is composed of refractory fibres, preferably high strength carbon fibres, with a metallic coating on the fibres which is composed of an under layer of a first metal and an over layer of a second metal. The over layer is of a highly conductive material such as silver and the under layer which improves coherence and adhesion of the over layer and thereby produces a very low brush voltage drop, is of a material such as nickel.

Abstract: A laminated glass windshield having incorporated with it an antenna of tarnished silver that is produced by applying a silver-frit paste to a surface of one glass sheet in a pattern of thin lines extending horizontally across the upper portion of the sheet toward the middle and then downwardly into a crescent shaped figure, firing the applied pattern to the glass, and treating the lines of the pattern with sulfur. The lower edges of the plastic interlayer and the other glass sheet in the windshield are cut out to facilitate connection with a lead wire.

Abstract: A METHOD OF ATTACHING AN ELECTRODE TO A SEMICONDUCTOR ELEMENT COMPRISING THE STEPS OF APPLYING A CONTACT MIXTURE TO THE SEMICONDUCTOR ELEMENT AND FUSING THE MIXTURE TO THE ELEMENT. THE CONTACT MATERIAL COMPRISES SILVER, TITANIUM HYDRIDE AND A READILY OXIDIZABLE METAL SELECTED FROM THE GROUP CONSISTING OF ZINC, ALUMINUM, LEAD, TIN AND INDIUM. THE FUSION TEMPERATURE IS ABOVE THE TEMPERATURE AT WHICH THE HYDRIDE REDUCES THE OXIDE OF THE OXIDIZABLE METAL.
