  • Apparatus and process for the production of micro-pore free high ductility metal foil
    Patent number: 4956053
    Abstract: A process and apparatus for producing metal foil comprises supplying an isotopically polished continuous cathode, a high volume turbulent flow of electrolyte and rigorous filtration to exclude chlorides, sulfides, organics and other impurities from the electrolyte.

  • Extrusion of strip material
    Patent number: 4953382
    Abstract: A metal extrusion process and apparatus therefor in which a strip material of a rectangular shape may be produced by maintaining frictional engagement of the metal by passageway-defining surfaces of a member which is moved toward a die such that the frictional drag of the passageway-defining surfaces urges the metal through the die. The process utilizes strip material as the starting material which enables the extrusion of metal strip by the frictional drag process to be accomplished.

  • Polycaprolactone-deterred nitrocellulose propellant compositions and method
    Patent number: 4950342
    Abstract: Method for producing novel deterred granular nitrocellulose propellant powder compositions having a stable burn rate gradient. The invention comprises coating nitrocellulose propellant granules with a minor amount by weight of a polycaprolactone polymer which is soluble in nitrocellulose under conditions which cause the polymer to be gradually dissolved into the granules to produce maximum burn deterrence at the surface of the granules which gradually decreases inwardly therefrom to produce a desired burn rate gradient in the granules.

  • Method and apparatus for forming ultra-small optical fiber cable assemblies
    Patent number: 4949894
    Abstract: A process and apparatus for fabricating an optical fiber cable core assembly having at least one optical fiber encapsulated with an ultra-small diameter metallic tube are described. The optical fiber cable core assembly is formed by passing a metal or metal alloy strip through at least one die to form the ultra-small diameter tube, inserting at least one optical fiber or fibers into the tube during the tube formation operation and passing the assembly through a sealing station to seal the tube and provide a hermetic core assembly. To reduce the likelihood of breaking the tube and damaging the optical fiber or fibers therein, the deformation energy for forming the strip into the tube is provided by wrapping the assembly about a tensioning device positioned between the tube forming station and the tube sealing station.

  • Thermal conductivity of substrate material correlated with atomizing gas-produced steady state temperature
    Patent number: 4945973
    Abstract: A molten metal gas-atomizing spray-depositing apparatus has an atomizer which employs a pressurized gas flow for atomizing a stream of molten metal into a spray pattern of semi-solid metal particles and producing a flow of the particles along with the gas flow in a generally downward direction. The apparatus also has a substrate disposed below the atomizer for impingement on the substrate of the gas flow at a steady state temperature resulting from heat transfer by the metal particles to the gas flow and for receiving a deposit of the particles in the spray pattern to form a product thereon.
