  • Patent number: 7048832
    Abstract: A method and system for extracting hydrocarbon fuel products from plastic material provides extraction of usable fuel components from waste plastic materials. The materials (or hydrocarbon portion thereof) are liquified and introduced to a chamber where the liquid material is agitated and a negative relative pressure (vacuum) is applied. The liquid is maintained at a substantially constant temperature and the vacuum draws the off-gas hydrocarbon products out for condensation and further processing, while unconverted char is removed to an ash dump. An auger feed unit with agitator buckets is used to propel the char through a feed while agitating the liquid to enhance the rate of gas removal.

  • Patent number: 5562659
    Abstract: A method for producing an exceptionally durable electrical insulation coating for electro-surgical instrumentation with excellent insulative properties in the 500 KHZ to 1 MHZ frequency range which can drastically reduce, if not totally eliminate, many problems of current electrical insulation materials in use. A process of ceramic plasma deposition is used. A thin ceramic coating can be readily applied to new or existing mono/bipolar surgical instrumentation.
