  • Mammary implant
    Patent number: 4592755
    Abstract: A prosthesis for subcutaneous implantation such as a mammary implant used in reconstructive surgery is made from a polyphosphazene elastomer (e.g. polyfluoroalkoxy phosphazene) sac containing a silicone gel. The sac is essentially impermeable to the silicone gel fill and overcomes a gel migration problem encountered with implants made using polysiloxane sacs.

  • Process for producing glass fiber reinforced injection molding compounds
    Patent number: 3932573
    Abstract: A process for preparing improved glass fiber reinforced thermoplastic compositions, the products produced thereby, and articles injection molded from the thermoplastic compositions. The process includes mixing and plastifying a powdered thermoplastic resin containing glass fibers in a screw extruder, milling the plastified resin-glass blend into a sheet on a hot roll mill, and dicing the sheet into pellets. The pellets are particularly suitable for use in forming articles by injection molding.
