  • Polymerization process
    Patent number: 5712352
    Abstract: The present invention relates to a continuous process for the polymerization of olefin(s) utilizing a metallocene catalyst or catalyst system in a continuous slurry or gas phase polymerization process. The invention is more particularly drawn to a gas phase polymerization process for polymerizing one or more olefin(s) in the presence of a metallocene catalyst system in a fluidized bed reactor in the absence of or with a low mount of a scavenger.

  • Custom denture fabrication technic
    Patent number: 4517043
    Abstract: A method of fabricating a custom denture using a preformed tooth arch and a custom formed denture base, attaching these units with a self polymerizing plastic, using a plasterless keying articulator in conjuction with an occlusal translator thereby completing the entire fabrication of a custom denture on the articulator without the conventional waxup, flasking, processing which is the present state of the art.

  • Plasterless articulator
    Patent number: 4337039
    Abstract: A dental articulator for mounting stone models without the need of plaster, by the use of a flexible model former with a rim around its edge and a square raised nipple, a ferromagnetic disc, magnets and a square keying device on the articulator. This method permits rapid articulation. The models may also be removed and replaced at will while maintaining the previously established centric.
