  • Publication number: 20040135280
    Abstract: An improved apparatus and process for the production of isocyanate derived fiber reinforced materials by reactive processing. The improved apparatus comprises a mixing apparatus containing a mixing chamber, means for the metered introduction of at least two liquid reactive chemical streams into the chamber, means for introduction of reinforcing fibers into the chamber, an outlet duct for conducting a liquid reaction mixture comprising reinforcing fibers from the mixing chamber, and at least five gas jets suitably arranged to promote the fluidization and improved mixing of the liquid reaction mixture with the reinforcing fibers as the liquid reaction mixture comprising reinforcing fibers emerges from the outlet tube. Also disclosed is an improved process for producing fiber reinforced composites by employing the apparatus, and composites prepared according to the improved process.

  • Patent number: 4869648
    Abstract: A fuel pumping apparatus includes a high pressure pump and a low pressure pump contained in a housing and driven by a drive shaft which is coupled to a rotary part of an internal combustion engine. The low pressure pump is a vane pump having a rotor in which is formed a plurality of outwardly extending slots which accommodate outwardly spring loaded vanes. The edges of the vanes engage an eccentrically disposed surface formed on a stator. The pump has end plates and inlet and outlet ports communicating with the space defined between said surface and the outer surface of the rotor. The outer edges of each vane are formed with grooves which extend along the edges and the grooves communicate by way of passages with the inner ends of the respective slots.
