Abstract: This application is directed to a process of forming a laminate. The steps include providing a glass and a metal foil of either deoxidized copper alloy or oxygen-free copper alloy. The glass is heated at a temperature of between about 600.degree. to about 1025.degree. C. with a viscosity between about 10.sup.3 to about 10.sup.8 poise. Then it is pressed against the foil and cooled to chemically bond it to the foil and form a laminate of a metal foil and a substantially pore-free glass.

Abstract: The present invention is directed to the process of forming a multi-layer or hybrid circuit assembly. The assembly includes at least one ceramic substrate having a deoxidized or oxygen free copper alloy foil bonded thereto by a bonding glass. The copper alloy foil may be a circuit to which a resistive metal alloy tape can be bonded so as to provide a path of precise resistance. Also, layers of foil may be glass bonded to a substrate and stacked to form multi-layer circuits.

Abstract: This invention relates to a laminated glass capacitor and method of making the capacitor. The capacitor is constructed of a plurality of internal electrodes stacked and having glass layers therebetween to give electrostatic capacity. External electrodes are connected to associated internal electrodes for taking out the electrostatic capacity. The glass layers are selected from a substantially pore free glass and the internal electrodes are formed of a metal foil selected from the group consisting of deoxidized copper alloy and oxygen free copper alloy.

Abstract: An improved monolithic hydrogenation catalyst and processes for using same to hydrogenate animal and vegetable oils, said catalyst being comprised of a Raney metal alloy surface layer integral with and derived from a selected nickel alloy monolithic substrate mesh structure wherein said surface layer is predominantly derived from an adherent Beta structured crystalline precursor outer portion thereon. The catalyst is adaptable to both continuous and batch hydrogenation and shows enhanced activity, improved triene to diene selectivity and a low isomerization index. Hydrogenated oils show lower linolenic and stearic contents, lower trans-isomer percentages and lower melting points as compared to commercial products of equivalent iodine number.

Abstract: Hydrogenation processes utilizing improved Raney nickel alloy catalysts are disclosed. The catalyst comprises a monolithic mesh type structure of a nickel alloy having an integral Beta phase Raney Ni.sub.x M.sub.1-x coating on its outer surfaces, where M is a catalytic activator selected from the group consisting of molybdenum, ruthenium, tantalum and titanium and where x, the weight fraction of nickel in the combined alloy, is between about 0.80 and about 0.95. The catalyst is effective in processes for hydrogenation of aromatic compounds of the type ##STR1## wherein K is either benzene or naphthalene, R.sub.1 is a hydrogen atom or an aliphatic chain containing from about 1 to about 9 carbon atoms or a phenyl radical, R.sub.2 is a hydrogen atom or an aliphatic chain containing from about 1 to about 3 carbon atoms, and R.sub.3 and R.sub.4 are hydrogen atoms, hydroxy, or nitro groups.

Abstract: A unique sintering method of developing a controlled porosity, controlled thickness, metal layer on a metal substrate is disclosed. The region to be coated is cleaned, a suitable adhesive applied and appropriate metal powder poured on. Additional layers of adhesive and powder can be applied to give desired thickness. Pore size is determined by the size and shape of the powder particles and by the degree of sintering selected. Controlled sintering of the particles is carried out at a temperature near the melting point of the metal in a hydrogen atmosphere to permanently attach the particles to the substrate. The sintering is only sufficient to bond the particles while avoiding over-sintering which would close the porosity.No foreign material is left, the adhesive being burned off during sintering. The porous surface thus produced provides secure anchorage for the ingrowth of body tissue in a prosthetic device such as a heart valve or bone implant.
