  • Process for fabricating an IR transmitting optical fiber
    Patent number: 5186870
    Abstract: The present invention is directed to a process for manufacturing a cladded optical fiber. The cladding and core are halide materials. An interface for inhibiting radiation scatter is provided at the boundary between the halide cladding and the halide core. The process steps include extruding a first halide or halide core from a first chamber, and extruding a second halide or halide cladding from a second chamber into contact with the halide core. The halide cladding is joined to the halide core at the boundary.
    Type: Grant
    Filed: December 17, 1987
    Date of Patent: February 16, 1993
    Assignee: Fuller Research Corporation
    Inventors: Terry A. Fuller, Vijay J. Nadkarni, John R. Peschke

  • Method for forming a plurality of objects from a plurality of superimposed sheets
    Patent number: 4411849
    Abstract: A process is provided for forming a plurality of objects simultaneously from a plurality of superimposed sheets of deformable and fusible material comprising the steps of heating said plurality of superimposed sheets until said material in said sheets reaches a temperature sufficient to allow plastic deformation while maintaining time, temperature and pressure conditions at the contiguous faces thereof below those causing fusion of said material and forming said plurality of superimposed sheets simultaneously.

  • Method of extruding bark and of forming a solid synthetic fuel
    Patent number: 3947255
    Abstract: A method of extruding bark and of forming a solid article, solid synthetic fuel or fireplace log comprising from about 60 to 95 percent by weight bark, which comprises physically blending pieces of combustible thermoplastic of an extrudable size with pieces of bark also of an extrudable size and having less than 7 percent preferably less than 2 percent moisture, to form a bark thermoplastic mixture of from about 60 to 95 percent by weight bark and about 2.
