1. An apparatus for the continual heat treatment of a filling contained within a crucible, said apparatus comprising:
- a. an oven having a ceiling with heating means transversely extending therethrough so as to locally heat a portion of said oven;
b. said portion comprising substantially the upper portion of said oven whereby a horizontally extending heating zone is formed;
c. at least one endless conveyor disposed within said oven, said conveyor having at least one portion thereof inclined relative to the horizontal axis of the upper portion of said oven;
said conveyor having crucible holders equally spaced along said conveyor and attached thereto;
said conveyor being moved by a driving means;
d. means for placing crucibles in said crucible holders;
e. means for preventing heat in said upper portion from extending throughout said oven;
said means for preventing having a portion of said conveyor disposed therein;
f. means for removing said crucibles from said crucible holders and said oven.

10. An apparatus for the manufacture of unidirectionally solidified articles by a continual zonewise heat treatment of a material contained within a crucible, said apparatus comprising:
-
a. an oven having heating means positioned therein which produce a vertical temperature distribution which encompasses the melting point of said material in said oven, said heating means being arranged so as to induce horizontally extending zones of equal temperature; b. at least one endless conveyor transferring a series of said crucibles through said oven along an inclined path relative to said horizontal heating zones, whereby said material within said crucible is subjected to varying temperatures, said conveyor further having crucible holders which receive said crucibles and is moved by a driving means; c. means for placing said crucibles in said holders and means for removing said crucibles from said holders.

11. An apparatus for the continual heat treatment of a filling contained within a crucible, said apparatus comprising:
-
a. an oven having a heating means disposed therein, said heating means extending parallel to the horizontal axis of said oven whereby a horizontal heating zone is formed; b. at least one endless conveyor disposed within said oven, said conveyor having at least a portion thereof inclined relative to the horizontal axis of said heating means, said conveyor having crucible holders affixed thereto and is positioned substantially above said heating means, said conveyor further having a driving means; c. means for placing crucibles in said crucible holders; d. means for removing said crucibles from said conveyor disposed above said heating means. - View Dependent Claims (12, 13, 14, 15, 16, 17)

18. A process for the continual heat treatment of crucibles having a filling disposed therein within an oven, said oven having a heating means disposed therein which creates a horizontal heating zone in said oven;
- at least one endless transport web having crucible holders attached thereto, said crucibles being positioned within said holders;
said conveyor having at least one portion thereof inclined relative to the horizontal axis of the oven, said process comprising;a. placing said crucibles onto said transport web; and
driving said transport web so as to move said crucibles;b. passing said crucibles through said heating zone wherein the filling within the crucible is melted; c. moving said crucibles along the inclined portion of said transport web and maintaining said crucible in substantial vertical relationship relative to the horizontal axis of said heating zone; d. subsequently moving said crucibles into a cooling zone wherein said filling can cool to a desired temperature; e. removing said cooled crucibles from said oven. - View Dependent Claims (19, 20, 21, 22, 23, 24)
- at least one endless transport web having crucible holders attached thereto, said crucibles being positioned within said holders;
