Abstract: Multiple pass method of applying printing paste upon a substrate wherein the method includes the application upon a substrate of a printing paste composition containing an inorganic particulate material, a pyrolyzable organic binder and a solvent system for the organic binder which comprises a low boiling temperature solvent and a high boiling temperature solvent. The method includes the steps of applying a first layer of the printing paste composition and the thermal removal of substantially all of the low boiling temperature solvent, but not the high boiling temperature solvent or binder, prior to superimposing the next pass or layer of printing paste having the same characteristics as the first layer thereover. Following the application of the desired number of layers and removal of low boiling temperature solvent in this manner, the high boiling temperature solvent and the binder are thermally removed and the inorganic particulate material is fused to the substrate.

Abstract: An automatically operable article transfer apparatus for successively picking up and transporting articles, such as the funnel components of cathode-ray tube assemblies, from a loading station to an article unloading station, and which during the course of transport of such articles is operable to effect a precise transpositional reorientation of each of the articles including pivoting or tilting the article, rotating the article and raising or lowering the article during such transport in such manner that all of such transpositional and reorientational movements are adjustably and cooperatively coordinateable to present the article in an adjustably preselectable and precisely predictable reoriented position at the work unloading station and which is further characterized by being designed to permit such orientational adjustability to be carried out to selectively vary the positional and orientational characteristics of the transfer apparatus at the work unloading station without disturbing the positional or

Abstract: Internal arcing in a cathode ray tube is substantially prevented by coating a portion of the interior of the funnel and neck of the tube with an electrically conductive composition, and coating a portion of the interior of the funnel and neck of the tube with an electrically resistive composition. The electrically conductive composition comprises about 10-30 weight percent iron and about 90-70 weight percent of a glass frit. The electrically resistive composition comprises about 8-24 weight percent iron, about 2-8 weight percent TiO.sub.2 and about 90-68 weight percent glass frit. The use of conventional "dag" coatings is eliminated. The cathode ray tube is especially useful as a picture tube in a color television receiver in which high operating voltages are employed.

Abstract: The present invention concerns sodium silicate and sodium aluminosilicate glass compositions which contain specified proportions of tantalum oxide and glass electrodes made therefrom, which are particularly sensitive to sodium ions in aqueous solutions containing sodium ions and other monovalent cations. These glasses represent an improvement over sodium aluminosilicate glass elctrodes of the type disclosed in U.S. Pat. No. 2,829,090.

Abstract: The drying characeteristics of a printing paste comprising a vehicle containing a binder and a low boiling point solvent are improved by substituting a high boiling point solvent for a portion of the low boiling point solvent without substantially adversely affecting the viscosity and flow properties of the paste. The printing paste is advantageously employed in silk screen printing in multiple passes where printed layers must have a uniform degree of wetness. The printing paste and vehicle are especially useful in the manufacture of microelectronic packages.

Abstract: A sealing glass and a sealing glass paste for sealing the face plate and funnel portion of a color television tube wherein PbO-containing sealing glass frit contains an effective amount of a powder, such as Pb.sub.3 O.sub.4 powder, which powder prevents the reduction of PbO to Pb metal during the sealing process, which reduction would otherwise result in a dielectric breakdown in the seal. Among other powders similarly found to be effective for the purpose of prevention of reduction of PbO in a PbO-containing sealing glass frit are certain other higher oxides of a cation which are selected from a group including, in addition to Pb.sub.3 O.sub.4, such higher oxides of a cation as BaO.sub.2, CrO.sub.3, MnO.sub.2, Mn.sub.2 O.sub.3, Fe.sub.2 O.sub.3, Fe.sub.3 O.sub.4, CuO, Cu.sub.2 O, Tl.sub.2 O.sub.3, Sb.sub.2 O.sub.5, TeO.sub.2, Ta.sub.2 O.sub.5, Nb.sub.2 O.sub.5, V.sub.2 O.sub.5, CeO.sub.2, Bi.sub.2 O.sub.3 and As.sub.2 O.sub.5. A sealing glass paste consisting essentially of a PbO-- B.sub.2 O.sub.
