  • Polymer emulsions with bimodal molecular-weight distribution
    Patent number: 5773505
    Abstract: The invention relates to polymer emulsions of poly(meth)acrylic acid esters and olefin copolymers suitable for improvement of the viscosity index, for use as oil additives.The polymer emulsion is formed of a continuous phase of poly(meth)acrylic acid esters and d-oligomers where the esters and oligomers have a bimodal molecular-weight distribution, a stabilizing agent (a graft or block polymerizate of an olefin copolymerizate and methacrylic acid esters), and a disperse phase of olefin copolymerizates distributed in the continuous phase.

  • Solution polymerization for the preparation of gel-free ethylene/vinyl acetate copolymers
    Patent number: 4937303
    Abstract: High molecular weight, gel-free ethylene/vinyl acetate copolymers may be prepared by the process of solution polymerization if a particular relationship of temperature/pressure is observed.
    Type: Grant

  • Fault-tolerant system employing multi-microcomputers using two-out-of-three majority decision
    Patent number: 4392199
    Abstract: A Fault-tolerant computer architecture employs a plurality of microcomputers connected in a partially meshed ring. Three device controllers are connected to any of the microcomputers by means of a passive switch, and a fault in data transmission relative to one microcomputer is resolved by a two-out-of-three decision. A failure of one microcomputer is manifested by an adjacent microcomputer, so that the down microcomputer is omitted from furthwr task assignments.
