    Abstract: Thick film resistive elements are prepared from an intimate admixture comprising silica, lead oxide and ruthenium dioxide or iridium dioxide which is heated to a temperature sufficient to provide a lead-containing glass having dispersed therein lead ruthenate or lead iridate. The lead-containing glass is comminuted and a resistor paste is formed which can be subsequently coated and fired on to a desired substrate to form the thick film resistive component. The method of this invention may facilitate the production of thick film resistors exhibiting a low temperature coefficient of resistivity, relative freedom from noise and drift, and high moisture resistance.

    Abstract: A novel Faraday-effect element having a refractive index highest along the axis and decreasing toward the surface is produced by immersing a thin elongated glass body containing an oxide selected from the group consisting of paramagnetic- and diamagnetic-type oxides composed of at least first cations, in a bath of salt including second cations having a smaller ration of the electronic polarizability to the third power of the ion radius than said first cations. The bath is maintained at a temperature to permit said second cations to diffuse into said glass body so that said first cations may be substituted by said second cations.
