  • Expansion compensated precision extrusion apparatus
    Patent number: 5449407
    Abstract: Extrusion apparatus and method includes a chamber of alterable volume having an outlet and a vent in a movable wall of the chamber to facilitate sealing the chamber upon application of force to the movable wall to displace viscous, fluid composition from within the chamber through the outlet and along a desired path. After displacement of a volume of the composition from the chamber, the vent is relieved to promote expansion of the composition within the chamber through the vent rather than through the outlet. The composition may be cured to substantially non-fluid condition along the desired path in response to applied thermal and/or ultraviolet radiant energy to provide traces of selected electrical properties on a work surface.
    Type: Grant
    Filed: February 1, 1994
    Date of Patent: September 12, 1995
    Assignee: Sophia Systems Co., Ltd.
    Inventors: Philip J. Breeden, Adam J. Bell, Joram Diamant, Edmund S. Lewandowski
