  • Patent number: 5289967
    Abstract: A method is provided for fabricating metal matrix composites. Optical or reinforcing fibers, which may be in the form of monofilaments, mats, or tow, are consolidated into a metal matrix alloy. Grooves may be provided in the metal matrix material for holding and positioning the fibers. A transient liquid diffusion bonding agent in the form of a powder may be blended with powdered filler material, such as powdered matrix material, to provide a vehicle for consolidating the fibers into the metal matrix. The fibers and the blended powder are placed between layers of the metal matrix material and the whole structure is heated under minimal pressure to liquefy the bonding agent. The liquid bonding agent wets each fiber and interdiffuses with the matrix material, resulting in rapid isothermal solidification of the alloy and consolidation of the fibers in the matrix.

  • Patent number: 5288585
    Abstract: A process for the preparation of a toner composition which comprises (1) mixing a water soluble monomer or monomers, and an oil soluble monomer or monomers with polymerization initiators, a crosslinking component and a chain transfer component; (2) effecting bulk polymerization until from about 10 to about 40 weight percent of the water soluble and oil soluble monomer or monomers have been polymerized; (3) cooling the product obtained; (4) mixing with the aforesaid partially polymerized product components comprised of charge control agents, pigments, dyes, initiators, chain transfer agents and crosslinking agents to formulate a uniform organic phase; (5) dispersing the organic phase into from between about 2 to about 5 times its volume of water containing from between about 1 to about 5 weight percent of a stabilizing component to form a suspension with an average particle size of from between about 5 to about 25 microns and a particle size distribution of from about 1.

  • Patent number: 5264314
    Abstract: A process for the preparation of toner compositions which comprises mixing at least one resin monomer with a polymerization initiator, a crosslinking component and a chain transfer component; effecting bulk polymerization until partial polymerization to near the onset of the gel-effect has been accomplished thereby forming an organic phase containing a partially polymerized component; mixing the aforementioned partially polymerized component organic phase with pigment or dye particles; dispersing the resulting organic phase in water containing a stabilizing component whereby there is obtained a suspension of toner particles in water; and polymerizing the toner suspension by heating.

  • Patent number: 5045132
    Abstract: High-energetic explosive and propellant compositions having decreased detonation sensitivity are provided. To enhance the specific impulse of these formulations and ensure detonation desensitization, the highly-energetic oxidizer 1,9-dinitrato-2,4,6,8-tetranitrazanonane is utilized.

  • Patent number: 4706037
    Abstract: A solenoid contactor arrangement facilitates soft contact between the movable and stationary contacts and provides for overtravel of an armature in a manner which ensures that good and consistent electrical contact is maintained between the movable and the stationary contacts. The movable contacts are carried on an axially reciprocable armature assembly and are afforded limited axial displacement relative thereto. The movable contacts are biased by a coil spring to a first position on the armature assembly in preparation for engagement with the stationary contacts. When that engagement occurs, the movable contacts stop, the spring yields, and further displacement of the armature assembly occurs until a stop on it firmly contacts and is stopped by a corresponding stop on the movable contacts. The spring is formed and positioned such that it does not dimensionally interfere with the firm contact between the movable contacts and the armature assembly.
