  • Patent number: 10403422
    Abstract: The present invention provides a magneto rheological fluid composition for use in a vehicle mount having a flexible body and a diaphragm. The magneto rheological fluid composition consists of a carrier fluid, a plurality of magnetic responsive particles dispersed in the carrier fluid and an anti-settling agent of fumed silica dispersed in the carrier fluid forming a thixotropic network with the carrier fluid suspending the magnetic responsive particles in the thixotropic network for preventing the magnetic responsive particles from settling. The magneto rheological fluid composition of the present invention contains no additional additives providing stability to the thixotropic network and to the magneto rheological fluid and preventing the flexible body and the diaphragm from reacting with the composition to prolong the life of the composition.
    Type: Grant

  • Patent number: 5753018
    Abstract: An improved friction material composite is disclosed that contains a fibrous reinforcing constituent, various friction imparting and controlling additives, and a thermosetting resin mixture in which mixture is contained pitch, a polyimide resin, and optionally a phenolic resin. Pitch-polyimide mixtures can be formulated to provide unusually high temperature resistance and strength and the pitch-polyimide-phenolic resin mixtures formulated to provide like properties at moderate cost.
