    Abstract: Electrically conductive adhesive compositions and methods for the preparation and use thereof, in which a solder powder, a chemically protected cross-linking agent with fluxing properties and a reactive monomer or polymer are the principal components. Depending upon the intended end use, the compositions comprise three or more of the following: a relatively high melting metal powder; solder powder; the active cross-linking agent which also serves as a fluxing agent; a resin; and a reactive monomer or polymer. The compositions are useful as improved conductive adhesives, such as for attaching electrical components to electrical circuits; the compositions comprising metal powder are ideally suited for creating the conductive paths on printed circuits. The compositions for forming conductive paths may first be applied to a substrate in the desired pattern of an electrical circuit, and then heated to cure it. During heating, the action of the cross-linking agent and optional reactive monomer or polymer within the mixture fluxes the metals, enabling sintering to occur between the metal powder and the solder powder.

    Abstract: Processes for coating three dimensional inorganic substrates, with shielded surfaces, with transition metal oxide-containing coatings are disclosed. Such processes comprise contacting a substrate with a transition metal oxide precursor, preferably maintaining the precursor coated substrate at conditions to equilibrate the coating, and then oxidizing the precursor to form a substrate containing transition metal oxide on at least a portion of the three dimensions and shielded surfaces of the substrate. Also disclosed are substrates coated with transition metal oxide-containing coatings for use in various applications including catalysis, shielding, heating and electro rheological applications using elements such as inorganic, fluid, porous and polymer matrix elements.

    Abstract: Transparent glass windows (88) comprising thereon titanium silicide (TiSi2) (82) as the principal solar screening layer for reducing transmission of near infrared and visible radiation. In some embodiments, a protective layer (84) of silicon or metal oxide, about 300 angstroms thick, is placed thereover. The protective layer serves to protect the silicide from oxidation during high-temperature processing procedures and increases the abrasion-resistance of the window product. The particular importance of titanium silicide film (82) is that it allows production of a window that is neutral in color when viewed in transmission as well as in reflection. Thus, one is able to provide a durable, pyrolytic, high-performance, color-neutral, solar-shielding window product.

    Abstract: Multilayer printed circuit boards are fabricated by preparing a first layer in conventional manner by forming a resist image on a copper clad substrate, etching away unwanted copper, removing the resist from the circuit pattern and optionally applying a dielectric mask such as conventional solder mask to selected portions of the circuit pattern. A second layer, and optionally one or more subsequent layers, are fabricated by providing an image of a second circuit pattern in a predetermined location on said first layer, the image being formed using a suspension of cuprous oxide in a curable resin material. The image is cured at least partially and subjected to chemical reduction to convert at least a portion of the cuprous oxide to metallic copper. The image is then electrolessly plated with copper to build up the circuit pattern and the latter is selectively coated with a dielectric mask before repeating the cycle to build up one or more additional layers. Solder can be applied to selected areas of any of said printed circuit layers at any appropriate time during fabrication. The above method of fabrication has advantages of economy of time, materials and labor as compared with methods hitherto employed to prepare multilayer boards in which a plurality of single boards are fabricated individually and then assembled as a sandwich or laminate by application of heat and pressure.
