Abstract
This disclosure depicts a feeder or bushing where the heat transfer members or fin shields have outwardly disposed surfaces with a ceramic coating bonded to those surfaces. The heat transfer surfaces also are in direct contact with and adjacent to the discharge wall of the feeder where they act as support members to support the discharge wall. This combination is especially useful in designing feeders or bushings with a greater number of orifices.

Apparatus for producing continuous filaments for streams of molten inorganic material comprising:
- feeder means having a discharge wall having orifices adapted to define the streams;
- attenuation means for mechanically drawing the molten streams into continuous filaments, the filaments advancing along a path;
- heat transfer means extending between the orifices adapted to remove heat from the molten streams, the heat transfer members being in direct contact with and adjacent to the discharge wall to act as a support member to support the discharge wall, the heat transfer members including outwardly disposed surfaces having bonded thereto a coating of crystallographically stabilized zirconia.
Apparatus for producing continuous filaments from streams of molten inorganic material comprising:
- feeder means having a discharge wall having orifices adapted to define the streams;
- attenuation means for mechanically drawing the molten streams into continuous filaments, the filaments advancing along a path;
- heat transfer members extending between the orifices to remove heat from the molten streams, the heat transfer members being in direct contact with and adjacent to the discharge wall to act as a support member to support the discharge wall, the heat transfer members including outwardly disposed surfaces having bonded thereto a coating of zirconia crystallographically stabilized with an effective amount of yttria, the heat transfer members each having a length and two ends;
- and
- manifolds connected to each end of the heat transfer members extending substantially perpendicularly to the lengths of the heat transfer members.
