  • Recycle process for polycondensation resins
    Patent number: 6797803
    Abstract: A method of recycling fusible polycondensation resin waste in a fusion polymerization apparatus is disclosed. The method of recycling polycondensation resins comprises adding polycondensation resin waste directly to a fusion polymerization apparatus to carry out the polycondensation reaction. The polycondensation resin waste may be supplied from any point of the polycondensation apparatus to carry out the exchange reaction and/or the polycondensation reaction between the resin being prepared in the apparatus and the resin waste supplied. The method may be carried out in a continuous fusion polycondensation system with more than one polymerization reactor connected in series.
    Type: Grant
    Filed: February 24, 2003
    Date of Patent: September 28, 2004
    Assignee: General Electric Company
    Inventors: Kazushige Inoue, Akio Ikeda, Takato Kimura, Tomoaki Shimoda, Masahiko Tatsumi

  • Photosynthetic culture apparatus and group of photosynthesis culture apparatuses
    Patent number: 6287852
    Abstract: A photosynthetic culture system has a culture bath holding an fluid containing plant microorganisms, carbon dioxide supplying means for supplying carbon dioxide to the fluid in the culture bath, light-conducting plate in the form of a flat plate placed oppositely to a light-receiving culture surface existing on the side of said culture bath, and light-receiving panel mounted on the upper end surface of the light-conducting plate. Further said light-conducting plate has the function of turning incident light from said light-receiving panel by right angles to conduct the light uniformly to said light-receiving culture surface of said culture bath.
